Answer:

AB/EF= 1/2, AC/EG= 1/2, CD/GH= 1/2, BD/FH= 1/2. The angles, being in a rectangle, will remain at 90°

Step-by-step explanation:

Since the shapes are rectangular, we already know that AB will be similar to CD and AC similar to BD.

In the first rectangle, AB is 10 units and in the second rectangle, GH is 20 units.

In the first rectangle, AC is 7 units and in the second rectangle, EG is 14 units.

This means the second rectangle is the first rectangle, but with all sides multiplied by 2.

Suppose that a sample of size 100 is to be drawn from a population with standard deviation L0. a. What is the probability that t

NARA [144]

Answer:

The probability that the sample mean will lie within 2 values of μ is 0.9544.

Step-by-step explanation:

Here

the sample size is given as 100
the standard deviation is 10

The probability that the sample mean lies with 2 of the value of μ is given as

$P(| \bar{X}-\mu|$

Here converting the values in z form gives

$P(-2$

Substituting values

$P(-2$

From z table

$P(z\leq 2)=0.9772\\P(z\leq -2)=0.0228\\P(-2\leq z\leq 2)=P(z\leq 2)-P(z\leq -2)\\P(-2\leq z\leq 2)=0.9772-0.0228\\P(-2\leq z\leq 2)=0.9544\\$

So the probability that the sample mean will lie within 2 values of μ is 0.9544.

In a young woman's study group, 7 percent of the students are from the town where the young woman's school is located, 80 percen

Umnica [9.8K]

Answer: the percent of study group students from outside the state is 13%

Step-by-step explanation:

The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%

The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.

Since the rest are from outside the state, the percent of study group students from outside the state would be

100 - (80 + 7) = 100 - 87 = 13%
