Answer:
(-35,0)
Step-by-step explanation:
To find the x-intercept, you first have to find the slope. To do this you find change in y over change in x. So that would look like:
Which would result in:
That means that every time you rise 17, you go right 11.
If you then taks the highest point, (-57,-34) you can rise 17 twice to get to a y-coordinate of zero, so that means you have to go right 22, making the x-intercept
(-35,0)
Answer:
a. answer choice c
b. 20301
Step-by-step explanation:
You first need to understand a formula for finding the sum of consecutive integers starting from one: (m*(m+1))/2, m is the biggest number in the set.
a. The biggest number in your set is 100, so we plug in 100 for m and solve:
100*101/2=50*101=5050
b. Same thing. Use the formula t plug in 201 for m:
201*202/2=201*101=20301
The only reason you have the picture next to your question is to prove the formula (m*(m+1))/2.
Do you mean 5+7?
If so, that equals 12!
First, find the z-score:
z = (value - mean) / sdev
= (275 - 280) / 15
= - 0.33
In order to use a standard normal table, we need a positive z-score:
P(z < -0.33) = 1 - P(z < 0.33)
Looking at the table, we find P(z < 0.33) = 0.6293
Therefore:
P(z < -0.33) = 1 - 0.6293 = 0.3707
Hence, you have a probability of about 37% <span>that a randomly selected pregnancy lasts less than 275 days.</span>
Answer is 5 hours
660/275 = 12/x
660x = 275 (12)...>cross multiply
66x = 3300
x =3300/660
x = 5
