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.
If you do 27-12 (which is 15) you add 15 to 13 and 20
Answers:
1. P=3
Step by step:
P-5=-2 -move the constant to the right hand side and change its sign
P=-2+5 - calculate the sum
P=3
2. W=-2.8
Step by step:
W+13.2=10.4 - move the constant tot he right hand side and change its sign
W=10.4-13.3 - calculate the difference
W=-2.8
3. X=2/3
Step by step:
X-5/6=-1/6 - move the constant to the rig hand side and change its sign
X=-1/6+5/6 - calculate the sum
X=2/3
Answer:
x=24
Step-by-step explanation:
We can set up an equation:
2/3 * x = 16
Multiplying both sides by the reciprocal of 2/3 to isolate the variable, we get
3/2 * 2/3 * x = 16* 3/2
1*x=24
x=24
