Angle 2 = 22 degrees (that line is dividing that angle into 1 & 2 equivalently)

Angle 3 = 90 degrees.

An SRS of 25 recent birth records at the local hospital was selected. In the sample, the average birth weight was = 119.6 ounces

deff fn [24]

Answer:

B. N(μ, 1.30).

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .

In this problem, we have that:

An SRS of 25 recent birth records at the local hospital was selected. In the sample, the average birth weight was = 119.6 ounces. Suppose the standard deviation is known to be σ = 6.5 ounces.

Assume that in the population of all babies born in this hospital, the birth weights follow a Normal distribution, with mean μ.

This means that for the sampling distribution, the mean is the mean of the weight of all babies born, so $\mu$ and $s = \frac{6.5}{\sqrt{25}} = 1.30$ .

So the correct answer is

B. N(μ, 1.30).

A flock of Canadian geese migrated 1623 miles in 28 days. What was the average rate at which these geese traveled in miles per d

Nostrana [21]

It's asking for miles/day (miles per day) meaning you would divide the number of miles by the number of days. So divide 1623 by 28.
1623/28=57.964

Which of the following ordered pairs is a solution of the given system of

Artist 52 [7]

Answer:

x=-14 and y = 9

Step-by-step explanation:

hello

4x + 8y = 8 <=> divide by 4 both parts

(1) x + 2y = 4

(2) x + 3y = 13

(2) - (1) gives

x + 3y -x - 2y = 13 - 4 = 9

<=> y = 9

we replace in (1) x + 2*9 = 4

<=> x = 4 - 18 = -14

so x = -14

hope this helps
