The answer would be -25.
Before we get to the solution, we need to remind ourselves that integers are whole numbers, but they include even negative numbers.
First we need to look at least two factors of 24.
Positive:
24 x 1 = 24
12 x 2 = 24
8 x 3 = 24
6 x 4 = 24
Negative:
-24 x -1 = 24
- 12 x -2 = 24
-8 x - 3 = 24
-6 x -4 = 24
Now lets add these factors and see the sum of each of these factors:
24 + 1 =25
12 + 2 = 14
8 + 3 = 11
6 + 4 = 10
-24 + -1 = -25
- 12 + -2 = -14
-8 + - 3 = -11
-6 + -4 = -10
Its 14 (20 chars limit thing)
Answer:
The P-value is 0.0234.
Step-by-step explanation:
We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.
Let = population mean.
So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}
Alternate Hypothesis, : > 100 {means that the population mean is more than 100}
The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;
T.S. = ~
where, = sample mean = 98
s = sample standard deviation = 20
n = sample size = 400
So, the test statistics = ~
= -2
The value of t-test statistics is -2.
Now, the P-value of the test statistics is given by;
P( < -2) = 0.0234 {using the t-table}

9. D
10.C
for 7 & 8 you use the equation
your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
