Answer:
m = 21, b = 28
Step-by-step explanation:
1. The equation is written in slope-intercept form, meaning it follows this equation: y = mx + b.
2. As you can see, 21 is the value plugged in where m is, and 28 is the value plugged in where b is.
Therefore, m = 21, and b = 28.
Answer:
√1762
Step-by-step explanation:
Square root of 1762
How?
Well 41^2+9^2=c^2
1681+81=c^2
1762=c^2
c=√1762
Answer:
The probability that the sample proportion is between 0.35 and 0.5 is 0.7895
Step-by-step explanation:
To calculate the probability that the sample proportion is between 0.35 and 0.5 we need to know the z-scores of the sample proportions 0.35 and 0.5.
z-score of the sample proportion is calculated as
z=
where
- p(s) is the sample proportion of first time customers
- p is the proportion of first time customers based on historical data
For the sample proportion 0.35:
z(0.35)=
≈ -1.035
For the sample proportion 0.5:
z(0.5)=
≈ 1.553
The probabilities for z of being smaller than these z-scores are:
P(z<z(0.35))= 0.1503
P(z<z(0.5))= 0.9398
Then the probability that the sample proportion is between 0.35 and 0.5 is
P(z(0.35)<z<z(0.5))= 0.9398 - 0.1503 =0.7895
Answer: The line starts at 1 positive, then from there go -4 (so go to the left) then 1 down from that point.
Step-by-step explanation: the problem is supposed to have been Y= -4/1 +1
