Answer:
H0: μc ≤ μs Ha :μc > μs
Step-by-step explanation:
The null and alternate hypotheses can be stated as
H0: μc ≤ μs Ha :μc > μs one tailed test
Where
μc = Mean of college students watching movies in a month
μs = Mean of school students watching movies in a month
For one tailed test of α =0.05 the value of Z= ± 1.645
The critical region will be Z > ± 1.645
It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1
Vertical angles equal eachother
set angle 4 and angle 8 equal to eachother
3x=x+40
-x both sides
2x=40
÷2 both sides
x=20
solve for angle 4
3 (20)
60 B
X= 30
That’s the answer I think
Answer:
2 (13a -5)
Step-by-step explanation:
Work Shown:
The GCF of 26 and 10 is 2. This is the largest factor that goes into both.
26a = 2*13a
10 = 2*5
So,
26a - 10 = 2*13a - 2*5 = 2(13a-5)
I'm using the distributive property to factor the 2 out.
Answer:
x = 5.4
Step-by-step explanation:
4/3 = 0.75
7.2*0.75 = 5.4
