2 is a factor of 10
a is a factor of a and a2
only 10ab has b, so b is not a factor
hence the answer is 2a

In a sample of 138 tables, the average height was found to be 32.6in. with a variance of 2.8. Give a point estimate for the popu

vesna_86 [32]

Answer:

$\hat{\sigma}^2 = 2.8$

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 138

Average = 32.6 inch

Population variance,

$\sigma^2 = 2.8$

We have to find a point estimate for the population variance of the height.

The point estimate for the population variance is the population variance itself.

$\hat{\sigma}^2 = \sigma^2 = 2.8$

Thus, the point estimate of population variance is the population variance that is 2.8.

I feel like u have to use sine, cosine, or tangent to solve this one. so since there isn’t hypotenuse, you would solve it by using tangent!!!

In an endurance race, Rachel ran

Reil [10]

Answer:

$31\frac{1}{5}\ miles$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

The distance is equal to multiply the speed by the time

we have

$speed=9\frac{3}{5}\ \frac{miles}{hour}$

$time=3\frac{1}{4}\ hours$

$distance=(9\frac{3}{5})(3\frac{1}{4})$

Convert mixed number to an improper fraction

$9\frac{3}{5}=9+\frac{3}{5}=\frac{9*5+3}{5}=\frac{48}{5}$

$3\frac{1}{4}=3+\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}$

substitute

$distance=(\frac{48}{5})(\frac{13}{4})=\frac{624}{20}=31,2\ miles$

Convert to mixed number

$31.2\ mi=31+0.2=31+\frac{1}{5}=31\frac{1}{5}\ miles$
