Answer and explanation:

The two events of choosing jolly ranchers from each bag, first and second are independent events so the probability of first event AND second event will be multiplied

First bag has 4 red 2 green and one blue

Second bag has 4 red and 2 orange

what is the probability that he would choose a purple jolly rancher from the first bag and a red jolly rancher from the second

Probability = number of favourable outcomes /total number of favourable outcomes

The first bag does not have a purple jolly rancher and so probability is zero

the second bag's probability of choosing a red jolly rancher =4/6

probability of choosing a purple jolly rancher from first bag and red jolly rancher from second bag

=0*4/6=0

Answer=0

Answer:

1/3

Step-by-step explanation:

5/6 - 1/2

note that you could also write 1/2 as 3/6 since when divided you get half once again .

5/6- 3/6 = (5-3)/6= 2/6 = 1/3

Dividing 6x^2 + 26x^2 + 23x + 5 by 3x + 1 using the long division involves the use of groups or parts

The result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder

The dividend is given as:

6x^2 + 26x^2 + 23x + 5

And the divisor is 3x + 1

Divide 6x^3 by 3x:

Result = 2x^2

Multiply 2x^2 by 3x + 1

=> 6x^3 + 2x^2

Subtract 6x^3 + 2x^2 from 6x^3 + 26x^2 + 23x + 5

=>  24x^2 + 23x + 5

Divide 24x^2 by 3x:

Result = 8x

Multiply 8x by 3x + 1

=> 24x^2 + 8x

Subtract 24x^2 + 8x from 24x^2 + 23x + 5

=> 15x + 5

Divide 15x by 3x:

Result = 5

Multiply 5 by 3x + 1

=> 15x + 5

Subtract 15x + 5 from 15x + 5

=> 0

Write out the sum of the results

Result = 2x^2 + 8x + 5

Hence, the result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder

Step-by-step explanation:

Factor is something that is being multiplied together.

Answer:

y = 7.2

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = 25, then

10 = 25k ( divide both sides by 25 )

[tex]\frac{10}{25}[/tex] = 0.4 = k

y = 0.4x ← equation of variation

When x = 18, then

y = 0.4 × 18 = 7.2

Standard deviation is a measurement of a collection of values' variance or dispersion. The standard deviation of the data set is 2.474.

Step 1: Find the mean

Step 2: Find each score’s deviation from the mean

Step 3: Square each deviation from the mean

Step 4: Find the sum of squares

Step 5: Apply the formula

[tex]SD = \sqrt{\dfrac{\sum(x_i-\bar{x})^2}{n}}[/tex]

The data set that is given to us is {1, 4, 2, 2, 8, 7, 3}, now use the steps to calculate the standard deviation.

Step 1: Find the mean

The mean of the given data set can be written as,

[tex]Mean, \mu=\dfrac{1+4+2+2+8+7+3}{7} = 3.857[/tex]

Step 2: Find each score’s deviation from the mean

1 - 3.857 = -2.857

4 - 3.857 = 0.143

2 - 3.857= -1.857

2 - 3.857= -1.857

8 - 3.857 = 4.143

7 - 3.857 = 3.143

3 - 3.857 = -0.857

Step 3: Square each deviation from the mean

-2.857² = 8.162

0.143² = 0.02

-1.857² = 3.447

-1.857² = 3.447

4.143² = 17.165

3.143² = 9.877

-0.857²= 0.735

Step 4: Find the sum of squares

8.162+0.20+3.447+3.447+17.165+9.877+0.735 = 42.857

Step 5: Apply the formula

[tex]SD = \sqrt{\dfrac{\sum(x_i-\bar{x})^2}{n}}\\\\SD = \sqrt{\dfrac{42.857}{7}} \\\\SD= 2.474[/tex]

Hence, the standard deviation of the data set is 2.474.

explanation

Total amount saved in 1st case :

[tex]S_1=400+20t_1[/tex]

Total amount saved in 2nd case :

[tex]S_2=100+40t_2[/tex]

( Here [tex]t_1 \ and\ t_2[/tex] are number of months )

Let, after x months the amount saved in both cases is same.

So,

[tex]S_2=S_1\\\\100+40x=400+20x\\\\20x = 300\\\\x = 15\ months[/tex]

Amount saved :

[tex]S_1=400+20(15) =\$ 700[/tex]

[tex]S_2=100+40( 15)= \$700[/tex]

Hence, this is the required solution.

Four squares with size of 6 centimeters should be cut to produce the container of greatest capacity.

a) The volume of the box ([tex]V[/tex]), in cubic centimeters, is equal to the area of the base ([tex]A[/tex]), in square centimeters, multiplied by the height of the box ([tex]h[/tex]), in centimeters. The area of the surface is the product of the width ([tex]w[/tex]) and length (l), both in centimeters:

[tex]V = w\cdot l\cdot h[/tex]  

[tex]V = (36-2\cdot x)^{2}\cdot x[/tex]   (1)

The volume of the container is [tex]V = (36-2\cdot x)\cdot x[/tex] cubic centimeters. [tex]\blacksquare[/tex]

b) We need to apply first derivative analysis and second derivative analysis to determine the dimensions of the maximum squares to be cut:

[tex]-4\cdot (36-2\cdot x)\cdot x+(36-2\cdot x)^{2} = 0[/tex]

[tex]-4\cdot x + 36-2\cdot x = 0[/tex]

[tex]6\cdot x = 36[/tex]

[tex]x = 6[/tex]

[tex]V'' (x) = -4\cdot [(-2)\cdot x+(36-2\cdot x)]-4\cdot (36-2\cdot x)\cdot x + (36-2\cdot x)^{2}[/tex]

[tex]V''(x) = 8\cdot x-4\cdot (36-2\cdot x)-4\cdot (36\cdot x-2\cdot x^{2})+(36-2\cdot x)^{2}[/tex]

[tex]V'' (6) = -48[/tex]

Since [tex]V''(6) < 0[/tex], the critical value of [tex]x[/tex] leads to a maximum.

Answer:

Hope this helps any!

Step-by-step explanation:

Answer:

a) (-3, 0) and (7, 0)

b) If x = 7 then (7 - 7) = 0

   If x = -3 then (-3 + 3) = 0

c)  f(x) = x² - 4x - 21

   y-intercept  (0, -21)

Step-by-step explanation:

a)

x-intercepts are when f(x) = 0

Therefore, if f(x) = (x - 7)(x + 3)  then (x - 7)(x + 3) = 0

⇒ x - 7 = 0

⇒ x = 7

and

⇒ x + 3 = 0

⇒ x = -3

So x-intercepts are (-3, 0) and (7, 0)

b) If x = 7 then (7 - 7) = 0

  If x = -3 then (-3 + 3) = 0

c) Expand f(x) = (x - 7)(x + 3)

⇒ f(x) = x² + 3x - 7x - 21

⇒ f(x) = x² - 4x - 21

The y-intercept is when x = 0 ⇒  (0, -21)

Answer:

x = 15°

Step-by-step explanation:

Linear pair = 180°

⇒ (6x - 5) + (6x + 5) = 180°

⇒ 12x = 180°

⇒ x = 15°

Since line m is parallel to line n, (6x - 5) and (6x + 5) are a linear pair.

Linear pair means that the sum of two angles equaling 180°.

[tex](6x - 5) + (6x + 5) = 180[/tex]

Step-by step calculations:

Opening the parenthesis:

[tex](6x - 5) + (6x + 5) = 180 \\\\6x - 5 + 6x + 5 = 180[/tex]

Combining like terms:

[tex]6x - 5 + 6x + 5 = 180 \\\\ (6x + 6x) + (-5 + 5) = 180[/tex]

Simplify the LHS:

[tex](6x + 6x) + (-5 + 5) = 180\\\\(12x) = 180[/tex]

Divide 12 both sides and simplify:

[tex]\frac{12x}{12} = \frac{180}{12} \\\\ x = 15[/tex]

Thus, the value of x is 15.

Answer:

  (c)  $31.75

Step-by-step explanation:

First of all, you need to use some number sense to estimate an answer.

If the $900 loan had no interest, 1/3 of it would be paid off in each of the 3 years, or about $300 each year. You will be making 12 monthly payments each year, so the amount of principal being paid with each payment is $300/12 = $25. Any answer much above this amount will not make sense, so you can immediately reject all choices except $31.75.

__

The simple interest on the loan is ...

  I = Prt = $900×0.09×3 = $243

That, too, is divided among the 36 payments, so adds ...

  $243/36 = $6.75 to each of the $25 payments we calculated above.

The monthly payment is ...

  $25 +6.75 = $31.75

Answer:

Step-by-step explanation:

Vertices of the quadrilateral are (-4, 1), (-3, 2), (-1, 2) and (-2, 1).

If the given quadrilateral is dilated by ta scale factor of 1.5 about the origin.

Rule for the dilation,

(x, y) → (kx, ky) [k = scale factor]

New vertices of the quadrilateral after the transformation will be,

(-4, 1) → (1.5×4, 1.5×1)

        → (-6, 1.5)

(-3, 2) → (-4.5, 3)

(-1, 2) → (-1.5, 3)

(-2, 1) → (-3, 1.5)

Now the new points are rotated by 90° clockwise about the origin,

Rule for the rotation of the points,

(x, y) → (y, -x)

So the new vertices will be,

(-6, 1.5) → (1.5, 6)

(-4.5, 3) → (3, 4.5)

(-1.5, 3) → (3, 1.5)

(-3, 1.5) → (1.5, 3)

We can plot these points on the graph to form a new (image) quadrilateral.

Answer:

B

Step-by-step explanation:

3/8 is equal to 0.375, also known as 37.5%.

The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.

The experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.

In the question, we are given that Sarah hit the ball 3 times out of the 8 times.

We are asked to find the experimental probability (as a percent) that she will hit the ball next.

As we know, the experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.

∴ The experimental probability = The number of times Sarah hit the ball/The number of times she experimented = 3/8

or, The experimental probability = (3/8)*100 % = (3*25)/2 % = 75/2 % = 37.5%.

∴ The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.

Answer:

18[tex]\pi[/tex] yd.³ or 56.54867 yd.³

Step-by-step explanation:

The volume of a cylinder can be written as: height × base, where the base of the cylinder is [tex]\pi[/tex]r².

Since the radius (r) is half the diameter, it should be 1.5 or 3/2 yd.

r = 1.5

So, the area of the base of the cylinder is 1.5²([tex]\pi[/tex]), which is equal to 2.25[tex]\pi[/tex].

Now multiply that by the height, 8 yd.

2.25[tex]\pi[/tex] × 8 = 18[tex]\pi[/tex]

The area of the cylinder is 18[tex]\pi[/tex] or 56.54867

Answer:

56.55 yd.³ OR 56.52 yd.³

Step-by-step explanation:

The formula for the volume of a cylinder is; V=πr^2h

To find the volume let's put in the values they gave us.

Now: V=π times 1.5^2 times 8

(If you don't know what pi or π is its the area of a unit circle. So the area of a circle with diameter 2 or radius 1)

Continuing the volume would be 3.141592.. * 2.25 * 8 ( '*' indicates multiplication) Now the answer after you multiply would be approx. 56.54867 which rounded would be 56.55

V=πr^2h so 3.14*2.25*8 which would be 56.52 yd.³ (if this is the way you need it ignore ANY other answers)
