Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
Then, use the squares in the equation:
Then, subtract 100 from both sides to isolate b:
Finally, square root both sides to get your answer:
Then round to the nearest tenth which gives you 17.3.
The answer is...95/3...or 31.67
The vertex is (-1,2) thats all i know
Answer:
32
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using the proportion test
Null hypothesis: p <= 0.22
Alternative hypothesis: p > 0.22
Using the formula
z score = p - P /√ (P(1-P)/n)
Where p is 74/200= 0.37, P = 0.22, n = 200.
0.37-0.22 / √(0.22(1-0.22)/200)
0.15 / √(0.22(0.78)/200)
0.15 / √(0.1716/200)
0.15/ √0.000858
0.15 / 0.02929
= 5.1212
To help arrive at a conclusion, we have to find the p value, using a p value calculator at the 0.05 level of significant, the p value is less than 0.00001... Thus we would reject the null as there is sufficient statistical evidence to prove that the proportion is higher than that reported by the polling organization.
