Caleb is putting tile down in his bathroom and needs to know the perimeter of the floor. Two sides rectangular floor are 5 1/3 f

ladessa [460]

Answer:

20 1/6 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

= 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

= 10 8/12 ft + 9 6/12 ft = 19 14/12 ft . . . . . use common denominator of 1/12 ft

= 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

= 20 1/6 ft . . . . perimeter of Caleb's bathroom

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 105 and a standard deviation sigma equa

kondor19780726 [428]

Answer: 0.6827

Step-by-step explanation:

Given : Mean IQ score : $\mu=105$

Standard deviation : $\sigma=15$

We assume that adults have IQ scores that are normally distributed .

Let x be the random variable that represents the IQ score of adults .

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x= 90

$z=\dfrac{90-105}{15}\approx-1$

For x= 120

$z=\dfrac{120-105}{15}\approx1$

By using the standard normal distribution table , we have

The p-value : $P(90$

$P(z$

Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
