The probability of a defect units is 0.3174 by calculating the z-score of the greater than and less than value.
When the distribution is normal, we use the z-score formula.
Z = (X - μ)/σ
We have σ = 0.15 and units with weights less than 9.85 or greater than 10.15 ounces will be classified as defects.
μ = 10.15 - 0.15 = 9.85 + 0.15 = 10
Now, the probability that a unit is defective.
P(X ≥ 10.15)
1 subtracted by the pvalue of Z when X = 10.15
[tex]Z = \frac{10.15-10}{0.15}[/tex]
Z = 1 has a pvalue of 0.8413
1 - 0.8413 = 0.1587
P(X ≤ 9.85)
[tex]Z = \frac{9.85-10}{0.15}[/tex]
Z = -1 has a pvalue of 0.1587
P = P(X ≥ 10.15) + P(X ≤ 9.85)
P = 0.1587 + 0.1587
P = 0.3174

The solution for x is x ≤ -3/4.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
To solve for x in the inequalities:
5x - 4 ≥ 12 and 12x + 5 ≤ -4
We'll solve each inequality separately:
5x - 4 ≥ 12
Adding 4 to both sides, we get:
5x ≥ 16
x ≥ 16/5
So the first inequality is solved for x as x ≥ 16/5.
Now, 12x + 5 ≤ -4
Subtracting 5 from both sides, we get:
12x ≤ -9
x≤ -9/12
x≤ -3/4
The only values of x that satisfy both inequalities are those that are less than or equal to -3/4.
Therefore, the solution for x is x ≤ -3/4.

2.25 inches
4.5 inches
6.75 inches
12.75 inches
The height of the cylindrical tub of ice cream is 6.75 inches.
What is the surface area of a cylinder?A cylinder is a 3 dimensional shape which has a curved side and two circular surfaces. The total surface area can be determined by the expression;
total surface area of a cylinder = 2πr^2 + 2πrh
where r is the radius of it circular surface, and h is its height.
Considering the given question, we have;
total surface area of a cylinder = 2πr^2 + 2πrh
But total surface area = 183.69 square inches
r = D/2
= 6/ 2
r = 3 inches
Thus,
183.69 = 2*3.14*3^2 + 2*3.14*3*h
= 56.52 + 18.84h
183.69 - 56.52 = 18.84h
127.17 = 18.84h

Answer: The answer is (C) 6.75
Step-by-step explanation:
The formula for Surface Area is: SA = 2πr^2 + 2πrh
Let's do the first part: 2πr^2
So you need to find the radius, which is half the diameter. 6 is the diameter so half that, and you get 3.
Now, times 3 by itself
3 * 3 = 9
And then times 9 by 2
9 * 2 = 18
And times 18 by pi, 3.14
18 * 3.14 = 56.52
Now that we have our first value, lets move on to the second part of the formula: 2πrh
So we need the diameter, and the question gives us the value of the diameter.
6 is the diameter
so times 6 by pi, 3.14
6 * 3.14 = 18.84h (leave h there because we don't know the height)
Now do this:
183.69 = 56.52 + 18.84h
You cannot add 56.52 and 18.84h because they are not like terms
So take away 56.52 from both sides
56.52 - 56.52 = 0
183.69 - 56.52 = 127.17
Now divide 127.17 by 18.84h
127.17/18.84 = 6.75 inches

B. how much will it cost Laura to send 4 text and talk for 13 minutes
C. if Laura wants to send 18 texts and only has eight dollars how many minutes can she talk? Will this use all her money? if not how much money will she have left?
D. Solve equation for T.
A. The equation is given as C = 0.1T + 0.05M
B. It will cost Laura $1.05 to send 4 texts and talk for 13 minutes.
C. Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.
D. The equation for T is T = (C - 0.05M) / 0.1.
Step by step explanationA. The equation for the cost, C, of sending both texts and talking for M minutes is:
C = 0.1T + 0.05M
where T is the number of texts sent.
This equation assumes that each text costs 10 cents and each minute of talk time costs 5 cents.
B. To calculate the cost of sending 4 texts and talking for 13 minutes, we can use the equation from part A:
C = 0.1T + 0.05M
C = 0.1(4) + 0.05(13)
C = 0.4 + 0.65
C = 1.05
Therefore, it will cost Laura $1.05 to send 4 texts and talk for 13 minutes.
C. To determine how many minutes Laura can talk if she wants to send 18 texts and only has eight dollars, we need to use the equation from part A and solve for M:
C = 0.1T + 0.05M
8 = 0.1(18) + 0.05M
8 = 1.8 + 0.05M
6.2 = 0.05M
M = 124
Therefore, Laura can talk for 124 minutes if she wants to send 18 texts and has eight dollars.
This will cost her $6.20, which is less than the amount of money she has, so she will have some money left over.
subtract the cost of talking and texting from the amount of money she has:
Money left = 8 - 6.20
Money left = 1.80
Therefore, Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.
D. To solve the equation from part A for T, we can rearrange the terms:
C = 0.1T + 0.05M
0.1T = C - 0.05M
T = (C - 0.05M) / 0.1
Therefore, the equation for T is T = (C - 0.05M) / 0.1.

What is circumference ?Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.
The formula for the circumference of a circle is given by:

To calculate the circumference of the circular garden, we can use the formula:
C = 2πr
where C is the circumference, π is the mathematical constant pi (approximated as 3 in this case), and r is the radius. Plugging in the given values, we have:
C = 2 x 3 x 70
= 420 feet
Now, since the flowers are spaced every 4 feet, we can divide the circumference by 4 to find the number of flowers needed:
number of flowers = C / 4

Step-by-step explanation:
We can find the other point using the axis of symmetry.
The axis of symmetry for a parabola passes through the x coordinate of the vertex.
So our axis of symmetry is x=4, which is a vertical line.
For any point on a parabola curve except the vertex, there will two points that share the same y value. The two x coordinates of those points midpoints should be the axis of symmetry.
So,
If we know (0,-6) and the vertex is 4, let's find the other point
[tex]( \frac{0 + b}{2} = 4[/tex]
[tex]b = 8[/tex]
So our other point is
(8,-6).
So the answer to #1 is we found point (8,-6) by using the axis of symmetry. By reflecting the point (0,-6) about the vertical line x=4, we end up getting the point (8,-6)
To find q, q(x) has the same vertex, so it is (4,10).
We know the axis of symmetry is x=4, we also know the y intercept is 18 so we have point (0,18)
Using the axis of symmetry we will get (8,18).
So the graphs above are the graphs of p and q
The graph facing upwards is q
The graph facing downwards is p.
For #2, you can say we know the vertex is (4,10) and using the y intercept and axis of symmetry we found the other point on the curve.
I don't fully see the table but if the other coordinates have a higher y value, the vertex is a minimum.
Else, of the other coordinates have a lower y value, the vertex is a maximum.

X
40% of 75 = 40% x 75 = 3000
The error in the solution is that the answer is written as 3000 instead of 30.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100 and it is denoted by the symbol '%'.
Percentage of a number is calculated as dividing the number with it's whole and then multiplying with 100.
We have to find the percentage of 40% of 75.
That is, the number which corresponds to the 40 parts per 100 of the number 75.
40% of 75 = 40% × 75
= (40 / 100) × 75

The graph shows the number of game systems sold
since 2015. Based on this information, which function
best models the number of game systems sold in
millions x years since 2015?
Step-by-step explanation:
so, for x = 0, y = 30.5
that means the first answer is out.
for x = 1, y = 21.35
so, only
y = 30.5(0.7)^x
can be right.
all other functions have an y-value of way over 30.5 (because the factor of 30.5 is larger than 1).
and to verify :
30.5 × 0.7¹ = 30.5 × 0.7 = 21.35
correct.

The quadratic-like polynomial x⁶ + 8 has no real roots, that is, it has two complex roots. (Correct choice: B)
What polynomial cannot be factored using real numbers?
In this problem we must determine what polynomial has no real roots. From real algebra we remember that any polynomial of the form x²ⁿ + a², where a is a positive real number, has no real numbers. That is, the factor form of the polynomial is shown below:
(xⁿ + i a) · (xⁿ - i a)
In other words, any polynomial of the form x²ⁿ + a², a > 0, has two complex roots. Now, by direct comparison, we conclude that polynomial x⁶ + 8 has no real roots.

18/100 = .18
58 x .18 = 10.44
⇒ 58 + 10.44 = 68.44
Hence, Arun’s restaurant bill is $58, and he wants to leave the waiter an 18 percent tip. The correct answer is $68.44.
