Answer:
You will find it.
Explanation:
Replace the X value in each answer's formula with the table's value, then find the answer.
Ex: A. y = 4x + 4
if x = -1
=> y = 4.(-1) + 4 = 0 (not match y value in the table) => the answer is not A
-12n/35-13n/35
= (-12n-13n)/35
= -25n/35
= - 5n/7
Answer:
x = 19.
Step-by-step explanation:
By the tangent - secant theorem:
BD^2 = AB * EB
so:
8^2 = (x - 7 + 4) * 4
4(x - 3) = 64
4x - 12 = 64
4x = 64 + 12 = 76
x = 76/4
= 19.
X=2 is the answer hope it helps
Answer:
Step-by-step explanation:
a) H0: 
Ha: 
(Two tailed test at 5% significance level)
b) n=30
Mean difference = 
Std error of mean = 
b) Test statistic t = mean diff/std error = -1.552
df = 30-1 =29
p value=0.0657
c) Since p > 0.05 our signi. level, we accept null hypothesis.
There is no significant difference between the means.
d) Using critical value we find that test statistic is > critical value left
So accept H0
