75% = 0.75
1/6 = 0.166
3/8 = 0.385
0.625

ANS = 1/6, 3/8, 0.625, 75%

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

Answer:

(y+1)

Step-by-step explanation:

use quadratic formula.

you will get two values of y

y= 7/5 and y= -1

u can create factors using these values of y (making 0 subject)

for 7/5

7/5=y

7=5y

5y-7=0

zero becomes subject in such cases bcz there are no numbers left on that side

now for -1

-1=y

y+1=0

so your factors are 5y-7 and y+1

The graph shows the increase of the temperature over time in an oven what is the change in the y value and x value on the graph

Hatshy [7]

Let

x-------> the time in minutes

y-------> the temperature in Fahrenheit degrees

$A(2,150)\\B(3,190)$

we know that

the change in the y-values between two points is equal to

$(y2-y1)$

Substitute the y-values of the point A and B in the formula

$y2=190\\y1=150$

$(190-150)=40$

the change in the x-values between two points is equal to

$(x2-x1)$

Substitute the x-values of the point A and B in the formula

$x2=3\\x1=2$

$(3-2)=1$

therefore

the answer is

The change in the y-value is $40$ and the change in the x-value is $1$

A random sample of 200 people was taken. 90 of the people in the sample favored Candidate A. We are interested in determining wh

mafiozo [28]

Answer:

a. 1.44

Step-by-step explanation:

We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 40%.

At the null hypothesis, it is tested if the proportion is of at most 40%, that is:

$H_0: p \leq 0.4$

At the alternative hypothesis, it is tested if the proportion is of more than 40%, that is:

$H_1: p > 0.4$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

0.4 is tested at the null hypothesis:

This means that $p = 0.4, \sigma = \sqrt{0.4*0.6}$

A random sample of 200 people was taken. 90 of the people in the sample favored Candidate A.

This means that:

$n = 200, X = \frac{90}{200} = 0.45$

Value of the test statistic:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{0.45 - 0.4}{\frac{\sqrt{0.4*0.6}}{\sqrt{200}}}$

$z = 1.44$

Thus the correct answer is given by option a.
