The depth of the snow at Yellowstone National Park in April at the lower geyser basin was normally distributed with a mean of 3.

Leona [35]

Answer:

$X =4.94\ in$

Step-by-step explanation:

For a standard normal distribution of mean $\mu_z = 0$ and $\sigma_z = 1$

the statistic $Z = \frac{X - \mu}{\sigma}$

In this problem we look for the value of X that is 2 standard deviations above the mean.

If there are two standard deviations above the mean, then, in the standard normal distribution, the statistic $Z = 2$ .

Then, we clear X.

$2 = \frac{X -\mu}{\sigma}\\\\2\sigma = X - \mu\\\\\2\sigma + \mu = X\\\\$

Where:

$\sigma=0.52\\\\\mu=3.9\\\\X = 2(0.52) + 3.9\\\\X =4.94$

Due: Today Raven told Micah the perimeter of the swimming pool was 35 feet, the dimension of the pool were 5 ft by 7 ft. Micah s

pychu [463]

Answer: Micah

Step-by-step explanation:

Given

Raven told Perimeter of the swimming pool is $35\ ft$

Micah said Perimeter is $24\ ft$

The actual dimension of the swimming pool is $5\ ft\times 7\ ft$

Perimeter is given by $2(l+w)$

Using this, the perimeter is

$\Rightarrow P=2(5+7)\\\Rightarrow P=2\times 12=24\ ft$

$\therefore$ Micah statement is correct.

Explanation:

You can check your answer by making sure that each of the primes you found is actually a prime. (Compare to a list of known primes, for example.) After you have determined your factors are primes, multiply them together to see if the result is 73. If so, you have found the correct prime factorization.

<em>Additional comment</em>

73 is prime, so its prime factor is 73.

73 = 73
