Answer:
Step-by-step explanation:
x = the mom...y = joe
x = 3y - 2
x = 31
31 = 3y - 2
31 + 2 = 3y
33 = 3y
33/3 = y
11 = y <=== joe is 11

Answer: 42°
Step-by-step explanation:
Complimentary angles are angles sum up to make 90°
From the ratio given 7:8,
Add the ratios together and find the smaller angle as follows
7 + 8 = 15
Therefore,
⁷/₁₅ x 90 = 42°
The smaller angle is 42°
Answer:
5/6
Step-by-step explanation:
2+6+4=12
6+4=10
10/12=5/6
Answer:
The probability that no more than 70% would prefer to start their own business is 0.1423.
Step-by-step explanation:
We are given that a Gallup survey indicated that 72% of 18- to 29-year-olds, if given choice, would prefer to start their own business rather than work for someone else.
Let
= <u><em>sample proportion of people who prefer to start their own business</em></u>
The z-score probability distribution for the sample proportion is given by;
Z =
~ N(0,1)
where, p = population proportion who would prefer to start their own business = 72%
n = sample of 18-29 year-olds = 600
Now, the probability that no more than 70% would prefer to start their own business is given by = P(
70%)
P(
70%) = P(
) = P(Z
-1.07) = 1 - P(Z < 1.07)
= 1 - 0.8577 = <u>0.1423</u>
The above probability is calculated by looking at the value of x = 1.07 in the z table which has an area of 0.8577.
