The formula for finding the volume of a nose cone of an aircraft is V = (pi * d ^ 2 * h)/6 where d is the diameter of the base o

adell [148]

Answer:

$h=\frac{6V}{\pi d^2}$

Step-by-step explanation:

we have

$V=\frac{\pi d^2h}{6}$

Solve for h

That means ----> isolate the variable h

step 1

Multiply by 6 both sides

$6V=\pi d^2h$

step 2

Divide by $\pi d^2$ both sides

$h=\frac{6V}{\pi d^2}$

If 20% of a school was made up of out-of-district students last year, but the number of out-of-district students increased by 50

Nadya [2.5K]

Answer:

<h2>30% is enrolled out-of-district.</h2>

Step-by-step explanation:

According to the word problem, the number is increased by 50%.

To increase a number by a percent, multiply the number and the percent.

We can do this by changing both percents to decimals.

To change a percent to a decimal, divide it by 100.

$20/100 = 0.2$

$50/100=0.5$

The number is INCREASED by 50% so 0.5 would become 1.5.

$0.2 * 1.5=0.3$

<h2>0.3 = 30%.</h2>

The average score of all pro golfers for a particular course has a mean of 70 and a standard deviation of 3.0 (Think of these as

bija089 [108]

Answer:

0.477 is the probability that the average score of the 36 golfers was between 70 and 71.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 70

Standard Deviation, σ = 3

Sample size, n = 36

Let the average score of all pro golfers follow a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(score of the 36 golfers was between 70 and 71)

$\text{Standard error of sampling} = \displaystyle\frac{\sigma}{\sqrt{n}} = \frac{3}{\sqrt{36}} = \frac{1}{2}$

$P(70 \leq x \leq 71) = P(\displaystyle\frac{70 - 70}{\frac{3}{\sqrt{36}}} \leq z \leq \displaystyle\frac{71-70}{\frac{3}{\sqrt{36}}}) = P(0 \leq z \leq 2)\\\\= P(z \leq 2) - P(z \leq 0)\\= 0.977 - 0.500 = 0.477= 47.7\%$

$P(70 \leq x \leq 71) = 47.7\%$

0.477 is the probability that the average score of the 36 golfers was between 70 and 71.
