Nataly [62]

Answer:

a. Fred's margin of error is larger than Ted's.

Step-by-step explanation:

Margin of error of a confidence interval:

M = z\frac{\sigma}{\sqrt{n}}

In which z is related to the confidence level(the higher the confidence level the larger the value of z) \sigma is the standard deviation of the population and n is the size of the sample.

From this, we have that:

A higher confidence level leads to a larger margin of error.

A larger sample size leads to a smaller margin of error.

In this question:

Same confidence level.

Fred's sample is smaller, so his margin of error will be larger.

The correct answer is given by option a.

Could someone please help me with this
arsen [322]

Hey!

-------------------------------------------------

Point Slope Form: y - 7 = -5/2(x + 4)

Slope-intercept Form: y = mx + b

m = slope

b = y-intercept

We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.

We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.

-------------------------------------------------

Answer:

y = -5/2x - 3

Confused! Need help please!! Will mark brainliest!
ziro4ka [17]

Yo sup??

This question can be solved by applying the properties of similar triangles

the triangle with sides 5x and 20 is similar to the triangle with sides 45 and 35

The similarity property used here is called AAA ie angle angle angle property as all the three angles of the 2 triangles are equal.

therefore we can say

5x/45=20/36

x=5 units

Hope this helps

Graph each absolute value function. State the domain, range, and y-intercept.
SVEN [57.7K]

Answer:

The domain is  (-\infty,\infty) and its range is [3,\infty).

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function y=|x|. Its domain is x\in (-\infty,\infty) and its range is y\in [0,\infty).

The graph of the function y=|x|+3 is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is  (-\infty,\infty) and its range is [3,\infty).

To find th y-intercept you have to find y at x=0:

y=|0|+3=3.

Hence, the y-intercept is (0,3).
