here are five number cards
2,5,7,8,9

one of the cards is removed and the mean average of the remaining four number cards is 6

which card was removed
show your working

Answers

Answer 1

Answer:

7

Step-by-step explanation:

Since one card was removed:

6 = x/4

x = 6 X 4

x = 24

Then you sum the numbers on the five cards and subtract 24 from it

(2 + 5 + 7 + 8 + 9) - 24

= 31 - 24

= 7

Therefore card with number 7 was removed.

Answers

A graph of the image of the figure after a reflection across the x-axis is shown below.

What is a reflection over the x-axis?

In Mathematics and Geometry, a reflection over or across the x-axis is represented by this transformation rule (x, y) → (x, -y).

This ultimately implies that, a reflection over or across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate changes from positive to negative or negative to positive.

By applying a reflection over or across the x-axis to triangle GLQ, we have;

(x, y)                →      (x, -y)

G (3, 4)             →      (3, -(4)) = G' (3, -4)

L (1, 2)                →     (1, -(2)) = L' (1, -2).

Interquartile range 4, 6, 6 11 12, 13, 13, 13, 14

Answers

The required interquartile range of the given data set is 7.

To find the interquartile range (IQR), we first need to order the data set from least to greatest:

4, 6, 6, 11, 12, 13, 13, 13, 14

Next, we calculate the first quartile (Q1) and the third quartile (Q3).

Q1 is the median of the lower half of the data set. Since there are 9 numbers, the lower half consists of the first four numbers: 4, 6, 6, 11. The median of these numbers is the average of the middle two, which is (6 + 6) / 2 = 6.

Q3 is the median of the upper half of the data set. The upper half consists of the last four numbers: 12, 13, 13, 14. The median of these numbers is the average of the middle two, which is (13 + 13) / 2 = 13.

Now that we have Q1 = 6 and Q3 = 13, we can calculate the interquartile range (IQR) as the difference between Q3 and Q1:

IQR = Q3 - Q1 = 13 - 6 = 7

Therefore, the interquartile range of the given data set is 7.

A woodworker wants to build a jewelry box in the shape of a rectangular prism with a total volume of 61.3 cubic inches. The woodworker is going to use a very expensive exotic wood to build the box. He wants to choose the dimensions of the box so that the bases of the prism are squares and the box's surface area is minimized. What dimensions should he choose for the box? Round answers to 4 decimal places

Answers

Answer: the woodworker should choose the dimensions of the box to be approximately 3.825 inches by 3.825 inches by 1.603 inches, with a total surface area of approximately 33.512 square inches.

Step-by-step explanation:

Let the side length of the square base be x, and the height of the prism be h. Then the volume of the prism is:

V = x^2h

We're given that V = 61.3 cubic inches, so:

x^2h = 61.3

We want to minimize the surface area of the box, which consists of the area of the two square bases (2x^2) plus the area of the four rectangular faces (4xh). So the total surface area is:

A = 2x^2 + 4xh

We can solve the first equation for h:

h = 61.3/x^2

Substituting this into the equation for A, we get:

A = 2x^2 + 4x(61.3/x^2)

A = 2x^2 + 245.2/x

To minimize A, we take the derivative and set it equal to zero:

dA/dx = 4x - 245.2/x^2 = 0

4x = 245.2/x^2

x^3 = 61.3

x = (61.3)^(1/3)

x ≈ 3.825

So the length of each side of the square base should be approximately 3.825 inches. We can use the equation for h to find the height:

h = 61.3/x^2

h ≈ 1.603

So the height of the prism should be approximately 1.603 inches.

Therefore, the woodworker should choose the dimensions of the box to be approximately 3.825 inches by 3.825 inches by 1.603 inches, with a total surface area of approximately 33.512 square inches.

A square piece of sheet metal (24 in x 24 in)
is used to make an open box (no lid). Equal
squares are cut out of each corner, and the
edges are folded up to make the box.
What is the maximum volume, V, of the box?

Answers

The maximum volume of the box is 864 cubic inches.

Let side length of the square cut from each corner is x inches.

After cutting the squares from each corner, the remaining dimensions of the sheet metal will be:

Length: 24 - 2x inches

Width: 24 - 2x inches

Height: x inches

So, the volume of the box

V = (24 - 2x) (24 - 2x)  x

V = x(24 - 2x)²

To find the maximum volume, we can take the derivative of V with respect to x, set it to zero, and solve for x:

dV/dx = (24 - 2x)² - 2x(24 - 2x) = 0

4x² - 96x + 576 = 0

Solving the quadratic equation,

x = 6 and x = 12.

We can substitute x = 6 into the volume equation to find the maximum volume:

V = 6(24 - 2(6))²

V = 6(12)²

V = 6 x 144

V = 864 cubic inches

Therefore, the maximum volume of the box is 864 cubic inches.

the pot?
A. 1 liter
B.

Answers

Answer:The correct answer is C. 3 liters.

Step-by-step explanation:

To determine the total amount of liquid in the pot, we need to add the volume of the broth and the volume of the water.

The broth has a volume of 500 milliliters, and the water has a volume of 1,500 milliliters. Adding these together, we get:

500 mL + 1,500 mL = 2,000 mL

Since there are 1,000 milliliters in a liter, we can convert the volume to liters:

2,000 mL ÷ 1,000 = 2 liters

Therefore, the total amount of liquid in the pot is 2 liters.

In this case, the test statistic is calculated as follows:

z = (106/150 - 0.59) / sqrt(0.59(1-0.59)/150)

= 1.55

The p-value is calculated as the area under the standard normal curve to the right of the test statistic. In this case, the p-value is calculated as follows:

p-value = p(Z > 1.55)

= 0.123

Since the p-value is greater than the significance level of 0.01, we fail to reject the null hypothesis. Therefore, we cannot conclude that the population proportion is significantly greater than 0.59 at the significant level of 0.01.

We can conclude that x is equal to 3/4.

To find the value of x in the given scenario, where triangles AABC and ADEF are similar, we can use the concept of corresponding sides in similar triangles.

From the given information, we know that the lengths of sides AB and DE are in proportion with each other, as the triangles are similar. Let's denote the length of AB as a and the length of DE as b. Similarly, let's denote the length of BC as c and the length of EF as d.

Since the corresponding sides are in proportion, we can set up the following equation:

AB/DE = BC/EF

Substituting the given values, we have:

a/b = 6/8

To find the value of x, we need to determine the ratio of the corresponding side lengths. Dividing both sides of the equation by 6, we get:

a/6 = b/8

Cross-multiplying, we have:

8a = 6b

Now, we can solve for x by equating the two ratios:

a/b = 6/8 = 3/4

How to determine the measure of an exterior angle?

In Mathematics and Geometry, the measure of the sum of the angles of a convex quadrilateral, pentagon, and a nonagon is equal to 360 degrees. This ultimately implies that, the sum of all the exterior angles of a regular polygon must add up to 360 degrees.

Mathematically, the exterior angle of a regular polygon can be calculated by using this mathematical equation:

Exterior angle = 360/number of sides

40 = 360/number of sides

Number of sides = 360/40

Number of sides = 9 sides.

Additionally, the measure of each interior angle of a regular polygon can be calculated by using this mathematical equation:

Interior angles = [180 × (n - 2)]/n

Consider the function f(x)=x^3+16x^2+60x+40. If there is a remainder of −5 when the function is divided by (x−a), what is the value of a?

Answers

The value of "a" is approximately -3.784 when the function f(x) is divided by (x - a) and leaves a remainder of -5.

To find the value of "a" when the function f(x) = x^3 + 16x^2 + 60x + 40 is divided by (x - a) and leaves a remainder of -5, we can use the Remainder Theorem.

According to the Remainder Theorem, if a polynomial f(x) is divided by (x - a), the remainder is equal to f(a).

In this case, the remainder is -5, so we have f(a) = -5.

Substituting a into the function, we get:

f(a) = a^3 + 16a^2 + 60a + 40 = -5

Now, we need to solve this equation to find the value of "a."

a^3 + 16a^2 + 60a + 40 = -5

Rearranging the equation:

a^3 + 16a^2 + 60a + 45 = 0

To find the exact value of "a," we can use numerical methods such as factoring, synthetic division, or using a graphing calculator. Unfortunately, the solution to this equation is not straightforward and requires numerical approximations.

Using numerical methods or a graphing calculator, we find that the value of "a" is approximately -3.784.

Therefore, the value of "a" is approximately -3.784 when the function f(x) is divided by (x - a) and leaves a remainder of -5.

Evaluate and simplify the expression g(a+5) - g(5) completely when g(t)=2t^2.

Answers

Answer:

The simplified expression for g(a+5) - g(5) is 2a^2 + 20a.

Step-by-step explanation:

To evaluate and simplify the expression g(a+5) - g(5), we need to substitute the function g(t) = 2t^2 into the given expression.

Let's start by evaluating g(a+5):

g(a+5) = 2(a+5)^2

Expanding the expression:

g(a+5) = 2(a^2 + 10a + 25)

g(a+5) = 2a^2 + 20a + 50

Next, let's evaluate g(5):

g(5) = 2(5)^2

g(5) = 2(25)

g(5) = 50

Now we can substitute these values back into the expression g(a+5) - g(5):

g(a+5) - g(5) = (2a^2 + 20a + 50) - 50

Simplifying:

g(a+5) - g(5) = 2a^2 + 20a

Therefore, the simplified expression for g(a+5) - g(5) is 2a^2 + 20a.

b) What is the probability that at least 88% of the sample of 1600 young Americans will have earned their high school diploma?

Answers

(a) The distribution of the proportion of people in t high school diploma = 0.0158.

(b)  the probability that at least 88% of the sample of 1600 young Americans will have earned their high school diploma is extremely small.

Given that,

(a) Based on the central limit theorem, the normal distribution may be used to approximate the fraction of persons in the sample who have a high school diploma.

The mean proportion of individuals in the population who have earned their high school diploma can be estimated as

⇒ 879/1600 = 0.5494.

The standard deviation can be estimated as the square root of (0.5494*(1-0.5494)/1600)

=0.0158

b) To find the probability that at least 88% of the sample of 1600 young Americans will have earned their high school diploma,

We need to use the normal distribution with a mean of 0.5494 and a standard deviation of 0.0158.

We can standardize the value of 88% to the corresponding z-score:

z = (0.88 - 0.5494) / 0.0158

  = 20.99

Using a standard normal distribution table or calculator, we find that the probability of a z-score this large or larger is essentially zero,

So the probability that at least 88% of the sample will have earned their high school diploma is extremely small.

you and a friend have created a carnival game for your classmates. you plan to charge $1 for each time a student plays, and the payout for a win is $5. according to your calculations, the probability of a win is .05 what is your expected value for this game?​

Answers

Answer:

The expected value for this game is -$0.75, indicating that, on average, players would expect to lose $0.75 per game.

Step-by-step explanation:

Expected Value = (Probability of Winning * Payout for Win) - Cost of Playing

In this case:

Probability of Winning = 0.05

Payout for Win = $5

Cost of Playing = $1

Expected Value = (0.05 * $5) - $1

Expected Value = $0.25 - $1

Expected Value = -$0.75

Circle A is transformed into Circle B using a sequence of two transformations. The first transformation is a dilation centered at (6,0).

Answers

Circle B is dilation of 6 unit left and 4 unit down to the center of circle A.

We have to given that;

Circle A is transformed into Circle B using a sequence of two transformations.

And, The first transformation is a dilation centered at (6,0).

Here, Center of circle A is,

⇒ A = (6, 0)

And, Center for circle B is,

⇒ B = (0, - 4)

Hence, We get;

⇒ B = (6 - 6, 0 - 4)

⇒ B = (0, - 4)

Hence, Circle B is dilation of 6 unit left and 4 unit down to the center of circle A.

The measure of the indicated angles using available arc angles which subtends angles at the circumference are:

(5). ? = 103, (6). ? = 80°, (7). ? = 32°, and (8). ? = 110°

What is angle subtended by an arc at the center

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

So;

(5). m∠JBL + 92° = 180° {sum of opposite interior angles of a cyclic quadrilateral}

m∠JBL = 88°

arc angle (JK + LK) = 2(88)

arc angle JK = 176 - 70 = 106°

arc angle (JK + JB) = 2(?)

? = (106 + 100)/2

? = 103

(6). arc angle QR = 360° - are. QSR

arc angle QR = 360 - (80 + 120) = 160°

arc angle QR = 2(?)

? = 160/2

? = 80°

(7). arc angle GH = 2(m∠GFH)

m∠GFH = 116/2

m∠GFH = 58

m∠FGH = 90° {angle in a semi circle is a right angle}

? = 180 - (58 + 90)

? = 32°

(8). arc angle DCF = 360 - arc angle DEF

arc DCF = 360 - (68 + 72)

arc DCF = 220

arc DCF = 2(?)

? = 220/2

? = 110°

Therefore, the measure of the indicated angles using available arc angles which subtends angles at the circumference are: (5). ? = 103, (6). ? = 80°, (7). ? = 32°, and (8). ? = 110°

Find k so the product of the roots is -4 if 3x² + 5x + 3k = 0

Answers

Answer:

k = - 4

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ) , then the product of the roots is [tex]\frac{c}{a}[/tex]

3x² + 5x + 3k = 0 ← is in standard form

with a = 3 and c = 3k , then

[tex]\frac{c}{a}[/tex] = - 4 , that is

[tex]\frac{3k}{3}[/tex] = - 4 ( multiply both sides by 3 to clear the fraction )

3k = - 12 ( divide both sides by 3 )

k = - 4

If Margo walks 1/4 mile in 1/12 of an hour, what is her unit rate

Answers

To find the unit rate, we need to determine how much distance Margo covers in one unit of time. We can do this by dividing the distance by the time.

Distance = 1/4 mile

Time = 1/12 hour

Unit rate = Distance ÷ Time

Unit rate = (1/4 mile) ÷ (1/12 hour)

We can simplify this division by multiplying both the numerator and denominator by the least common multiple of 4 and 12, which is 12.

Unit rate = (1/4 mile) ÷ (1/12 hour) x (12/12)

Unit rate = (3/4 mile) ÷ 1 hour

Unit rate = 3/4 mile per hour

Therefore, Margo's unit rate is 3/4 mile per hour. This means that she can cover a distance of 3/4 mile in one hour of walking.

Answer:

3mph

Step-by-step explanation:

1/12 of an hour will be 5 min. In 5 min she can walk 1/4 mile then in one hour she can walk 1/4 x 12. This means her rate will be 3 miles per hour.

60/12 = 5

12 x 1/4 = 12/4 = 3
