The statement of the question tells us that 45% of the customers getting an oil change will have their car tires rotated. Therefore:
probability of both = 0.7 x 0.45
= 0.315
= 31.5%

Answer:

64.3%

Step-by-step explanation:

You are finding a conditional probability. You divide the second percent by the first percent.

P(B | A) = [P(A and B)] / P(A)

P(A) = 0.7

P(A and B) = 0.45

= 0.45 / 0.7

= 0.643

= 64.3%

Suppose the polynomial function below represents the power generated by a wind turbine, where x represents the wind speed in met

Elis [28]

Answer:

<em>f(10) or the power generated by the wind turbine at the wind speed of 10 m/s is </em><em>190.26 kW</em>

Step-by-step explanation:

The given polynomial function is,

$f(x) = 0.08x^3 + x^2 + x + 0.26$

where,

x represents the wind speed in meters per second,

y represents the kilowatts generated.

Putting x=10, we can get the value of f(10).

So,

$=f(10)$

$= 0.08(10)^3 + (10)^2 + (10) + 0.26$

$= 0.08(1000) + (100) + (10) + 0.26$

$= 80 + 100 + 10 + 0.26$

$=190.26$

Therefore,at x=10 or when the wind speed is 10 m/s, then y or the power generated by the wind turbine will be 190.26 kW

Solve –3 + c = –8.<br> A. -5 B. 11 C. 5 D.-11

sergey [27]

Answer:

The answer is A. -5

Step-by-step explanation:

Write out the equation:

-3 + c = -8 Add 3 on both sides to isolate the varible on one side

c = -5 -8 plus 3 is -5

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.

Eleven members of the Middle School Math Club each paid the same amount for a guest speaker to talk about problem solving at the

tiny-mole [99]

The missing digit is number 3. The total amount should be $132

I multiplied 11 by the numbers 10 and above to get the possible three digit answer who has 1 as the first digit and 2 as the last digit.

11 x 10 = 110
11 x 11 = 121
11 x 12 = 132

The 11 members of the Middle School Math club each paid $12 for a guest speaker.
