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)
like
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
Let
x-------> the time in minutes
y-------> the temperature in Fahrenheit degrees

we know that
<u>the change in the y-values between two points is equal to</u>

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


<u>the change in the x-values between two points is equal to</u>

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


therefore
<u>the answer is</u>
The change in the y-value is
and the change in the x-value is

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:

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

The test statistic is:
In which X is the sample mean,
is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
0.4 is tested at the null hypothesis:
This means that 
A random sample of 200 people was taken. 90 of the people in the sample favored Candidate A.
This means that:

Value of the test statistic:



Thus the correct answer is given by option a.
