Answer:
<u>Statement | Reason</u>
1. AB = CB | Definition of isosceles triangle
2. AD = CD | Definition of median
3. BD = BD | Reflexive property
4. ΔADB ≅ ΔCDB | SSS (Side-side-side)
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
1/2a - 1/2 = 1/2(a - 1)
You can factor out the 1/2.
Answer:
x < 9
Step-by-step explanation:
Given inequality:
6x + 9 < 63
Subtract 9 from both sides:
⇒ 6x + 9 - 9 < 63 - 9
⇒ 6x < 54
Divide both sides by 6:
⇒ 6x ÷ 6 < 54 ÷ 6
⇒ x < 9
Answer:
12
Step-by-step explanation:
Here we use SOHCAHTOA
Seeing as we have the hypotenuse and we are working to find out the opposite, we use SOH
Sin(x)= Opposite/Hypotenuse
Sin(45) = x/
×12 root 2
sin(45) times 12 root 2= 12
x=12
