a factory makes car batteries. The probability that a battery is defective is 1/13. If 200 batteries are tested about how many are expected t be defective.
A. 20
B. 15
C. 187
D. 13

Answers

Answer 1

Answer:

defective battery=200×1/13=15.3=15 is your answer

Answer 2

Number of expected defective batteries are option(B) 15

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

Probability that a battery is defective = [tex]\frac{1}{13}[/tex]

Total number of batteries = 200 batteries

Number of expected defective batteries = [tex]200(\frac{1}{13})[/tex] ≅15 batteries

Hence, the number of expected defective batteries are option (B) 15 batteries

Answers

Answer:

Step-by-step explanation:

The volume of the cylinder is 84 pi inches squared What can be concluded about the volume of the cone? Check all that apply.
The volume of the cone is One-third the volume of the cylinder.
The volume of the cylinder is 2 times the volume of the cone.
The volume of the cone is less than the volume of the cylinder.
The expression 84 pi over 3 finds the volume of the cone.
The expression 84 pi over 2 finds the volume of the cone.

Answers

The correct statements about the volume of the cone are:

- The volume of the cone is One-third the volume of the cylinder.

- The expression 84 pi over 3 finds the volume of the cone.

- The volume of the cone is less than the volume of the cylinder.

What is the volume of cylinder?

[tex]V=\pi\times r^2\times h[/tex]

where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder

What is the volume of the cone?[tex]V=\pi\times r^2\times \frac{h}{3}[/tex]

where 'r' is the radius of the base of the cone and 'h' is height of the cone

For given example,

The volume of the cylinder is 84 pi inches cubed.

Let [tex]V_1[/tex] represents the volume of the cylinder.

[tex]V_1=84~~cu.in.[/tex]

Using the formula of the volume of the cylinder,

[tex]V_1=\pi\times r^2\times h[/tex]

where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder

Let [tex]V_2[/tex] be the volume of the cone.

Assume that the base radius 'r' and height 'h' of the cone and the cylinder are equal.

Using the formula of the volume of the cone,

[tex]\Rightarrow V_2=\pi\times r^2\times \frac{h}{3}\\\\\Rightarrow V_2=\frac{1}{3}\times( \pi\times r^2\times h) \\\\\Rightarrow V_2=\frac{1}{3}\times V_1[/tex]

This means, the volume of the cone is One-third the volume of the cylinder.

[tex]\Rightarrow V2=\frac{1}{3}\times 84[/tex]

This means, the expression 84 pi over 3 finds the volume of the cone.

[tex]\Rightarrow V_2=28~~cu.in.\pi \\\\\Rightarrow V_2 < V_1[/tex]

This means, the volume of the cone is less than the volume of the cylinder.

Therefore, the correct statements about the volume of the cone are:

- The volume of the cone is One-third the volume of the cylinder.

- The expression 84 pi over 3 finds the volume of the cone.

- The volume of the cone is less than the volume of the cylinder.

Solve the equation 18+a= -50

Answers

18+a=-50
a+18=-50
Subtract 18 from both sides
a=-68

Answer:

-68

Step-by-step explanation:

Subtract 18 from each side of the equation.

a + 18 = -50

    -18    -18

Turn -50 - 18 into -50 + (-18) because you need to add the opposite.

a = -50 + (-18)

a = 68

Answers

Answer:

PEMDAS

Step-by-step explanation:

Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.

Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3

Then, go to your exponents. Since we don't have any, we skip this step.

Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.

Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.

The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.

Sansa shifted the parabola y = x^2 by 3 units to the right. Which of the following equations corresponds to the resulting graph?
А) y = x2 + 3
B) y = x2 + 9
C) y = x2 + 6x + 9
D)y = x2 - 6x + 9

Answers

Answer:

y = (x - 3)^2

Step-by-step explanation:

The original function is y = x^2.  Its vertex is at (0, 0).  Translating the graph h units to the right results in g(x) = (x - h)^2; h units to the left results in h(x) = (x + h)^2.

In this particular case we have y = x^2 and are translating the graph 3 units to the right.  Thus, the original function y = x^2 becomes y = (x - 3)^2.

The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.

The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.

What is a translation?

A translation happens when either a figure or a function are moved horizontally or vertically.

The four translation rules for functions are given as follows:

Left a units: f(x + a).

Right a units: f(x - a).

Up a units: f(x) + a.

Down a units: f(x) - a.

The parent function for this problem is given as follows:

f(x) = x².

For this problem, the parent function was moved:

2 units left, hence g(x) = f(x + 2).

4 units up, hence g(x) = f(x + 2) + 4.

Hence the function g(x) is defined as follows:

g(x) = (x + 2)² + 4.

I. 1 cup is $4.50

2 cups is $9.00

3 cups is $13.50

ll. 6 cups is $27.00

Step-by-step explanation:

Now since the number of cups is proportional to the total cost of frozen yoghurt,and the cost of 4 yoghurts cups where given .ie. $18.00

then 1 cup is $18/4 which is $4.50 per one cup, thus the other cost of cups are given.

therefore 6 cups is 6•18/4 which is $27.00.

hence 5 cups is 5•18/4 which is $22.50.
