a random sample of high school seniors were asked whether they were applying for college. the resulting confidence interval for

Artist 52 [7]

Using the confidence interval, the margin of error is 0.02.

In the given equation we have to find the margin of error.

The resulting confidence interval for the proportion of students applying for college is (0.65,0.69).

Let p = population proportion of students applying for college

P = Sample proportion of students applying for college

ME = margin of error

So the confidence interval

CI = (P-ME, P+ME)

From the given question;

(P-ME, P+ME) = (0.65,0.69)

So lower bound= P-ME = 0.65............................(1)

Upper Bound = P+ME = 0.69............................(2)

Simplifying the Equation 1 and 2

Add equation 1 and 2 we get

2P = 1.34

Divide by 2 on both side we get

P = 0.67

Putting the value of P in the equation 2

P+ME = 0.69

0.67+ME=0.69

Subtract 0.67 on both side we get

ME = 0.02

Hence, the margin of error is 0.02.

fran found this expression in her cookbook. 1/3 divided by 2.write a scenario that explains the expression and solve

This may help:

There are $\frac{1}{3}$ gallons of lemonade.

Two friends share the lemonade.

What fraction of the lemonade does each friend receive?

To solve you do kcf or keep change flip.

You keep $\frac{1}{3}$ and change division to multiplication.

Then $\frac{2}{1}$ is changed to $\frac{1}{2}$

The answer would be $\frac{1}{6}$

Hope That Helps!

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (–1, 5).

Anni [7]

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (–1, 5).

y = 4x – 2 has slope = 4
parallel lines have same slope so slope = 4

passes through the point (–1, 5).
y = mx+b
5 = 4(-1) + b
b =9

equation
y = 4x + 9

answer

The slope of y = 4x – 2 is 4
The slope of a line parallel to y = 4x – 2 is 4
The equation of the line parallel to y = 4x – 2 that passes through the point (–1, 5) is y = 4x + 9

Write the coefficient of a in 7 a

Arturiano [62]

Given:

The term is 7a.

To find:

The coefficient of "a" in the given term "7a".

Solution:

In the product of a number and a variable, the number is called the coefficient of that variable.

In the expression "7a", the number is "7" and the variable is "a". It means the number 7 is the coefficient of "a".

Therefore, the coefficient of "a" in the given term "7a" is 7.
