4 lines are shown. 3 lines intersect and extend from one point forming 2 angles. The top angle is labeled 1 and the bottom angle

is labeled 2. A fourth line intersects all 3 lines. When it intersects the middle line, it forms 4 angles. Clockwise, from the top, the angles are 3, 6, 5, 4. When it intersects the third line, it forms 4 angles. Clockwise, from the top left, the angles are 7, 8, blank, blank.
Which angle pairs are supplementary? Check all that apply.

∠1 and ∠2

∠4 and ∠3

∠4 and ∠5

∠7 and ∠5

Suppose babies born in a large hospital have a mean weight of 4095 grams, and a standard deviation of 569 grams. If 130 babies a
Butoxors [25]

Answer:

P =0.3998

Step-by-step explanation:

Let {\displaystyle {\overline{x}}} be the average of the sample, and the population mean will be \mu

We know that:

\mu = 4095 gr

Let \sigma be the standard deviation and n the sample size, then we know that the standard error of the sample is:

E=\frac{\sigma}{\sqrt{n}}

Where

\sigma=569

n=130

In this case we are looking for:

P(|{\displaystyle{\overline{x}}}- \mu|>42)

This is:

{\displaystyle{\overline{x}}}- \mu>42 or {\displaystyle{\overline{x}}}- \mu

P=P({\displaystyle{\overline{x}}}- \mu>42)+ P({\displaystyle{\overline{x}}}- \mu

Now we get the z score

Z=\frac{{\displaystyle{\overline{x}}}-\mu}{\frac{\sigma}{\sqrt{n}}}

P=P(z>\frac{42}{\frac{569}{\sqrt{130}}}) + P(z

P=P(z>0.8416) + P(z

Looking at the tables for the standard nominal distribution we get

P =0.1999+0.1999

P =0.3998

Chelsea is graphing the function f(x) = 20()x. She begins by plotting the initial value. Which graph represents her first step?
Soloha48 [4]

we have the function

f(x)=20(\frac{1}{4})^{x}

we know that

In the equation of the exponential function of the form

f(x)=a(b)^{x}

a is the initial value

b is the base

x is the exponent

The initial value is the value of the function when the value of x is equal to zero

in this problem

for x=0

f(0)=20(\frac{1}{4})^{0}

f(0)=20(1)=20

the initial value is the point (0,20)

therefore

the answer in the attached figure

Select the sequence of transformations that will carry rectangle A onto rectangle A'. A) reflect over y-axis, rotate 90° clockwi
Darina [25.2K]

Answer:

Any of the 4 sequences gives another rectangle

Explanation:

Any rotation or traslation you make over a rectangle wont change the fact that you have still a rectangle.

The same will happen if you make a reflection of any on the axis. Therefore any of the 4 sequences given will give you a rectangle.
