Please Help this is Due in 1 hour and I really dont understand any of this. (Question in Image)
1 answer:
Answer:
5.14
Step-by-step explanation:
The way i solved this was i found the length of the line by taking the 2 (Width and also "A") and the 7 (The height and also "B"), squared both of them and added them together. Then found the square root. Sense i suck at explaining things this is what the equation should have looked like. ÷ 2. (Side wait for someone else to answer because i'm 70% sure this is right.

Determine the number of bags sold
First, we need to determine the number of bags for 27 pears;
Since they are packed in 3s
Hence:
9 bags were used for 27 pears;
After 5 bags were sold, we have:
Recall that the pears are packed in 3s
So:
The equation of a line can be written as:
Where (xo, yo)=(3, 1)
The equation of the line is:
Where (xo, yo)=(3, 1)
The equation of the line is:
Answer:
a. 385
b. 342
Step-by-step explanation:
To solve the problem we do the following:
The equation to calculate the sample size is:
a)
We have the following data:
Since no estimate of proportion is given, we will assume: p = q = 0.5
We know that For 95% confidence, z = 1.96
Width = 0.10
Hence, the margin of error would be:
0.10 / 2 = 0.05
E = 0.05
And so we can calculate sample size:
n = 385
b)
We have the following data for this point:
p = 2/3
q = 1 - p
q = 1 - 2/3
q = 1/3
And so we can calculate sample size:
n = 342
