Answer:
554
Step-by-step explanation:
554 trust meh dude
The answer would be B 21/4
1. It is important to go through each of the words given in the question to get through to the actual answer. The function will be:
y= (4 * x) - 5
= 4x - 5
2. The function of this statement will be
(h/3) + 2.5 = w
1. Let us assume the price of a pizza = p
From the first part we can write
p = $6.95
On adding the price of each topping "t" we get
p = $6.95 + ($0.95) * t
= <span>$6.95 + $0.95t</span>
I hope it helps you.
I'm not sure what you mean, but if you mean 15 and 1/20th, you just multiply 15 by 20 and add one which is 301 and keep the denominator
Answer:
And rounded up we have that n=656
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 80% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
Solution to the problem
The margin of error for the proportion interval is given by this formula:
(a)
Since we don't have prior info for the proportion of interest we can use 
as estimator. And on this case we have that 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=656
