Answer:
0.6604
Step-by-step explanation:
Given that a market research firm knows from historical data that telephone surveys have a 36% response rate.
Sample size of random sample = 280
We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error
= 
Substitute p = 0.36 and q = 1-0.36= 0.64
p follows N with mean = 0.36 and std dev = 
Using normal distribution values we can find\
Answer:
D
Step-by-step explanation:
the square root of 24 is 4.8 so it has to be D
Answer:
No
Step-by-step explanation:
When you plug in the numbers, you get:
9>6+3
9 is equal to 9, not greater than.
THe problem is basically telling us: 
where P is the power disappated and V^2 is our voltage squared.
So, for the second example to find the power we simply have to plug k and our voltage back in, so:
Answer:
so i wrote the steps but not the answers, if you want i can write the answers too
Step-by-step explanation:
hello! so here all you have to do is substitute the given points of x to the equation. then you put two points on the graph. (two points on each graph) i can write the answers if you want, but please try first! if you cant ill help some more and show how to do it.
