-3.5, -3, -2 1/2, -2, 2.5
Step-by-step explantion:
The more you have with a negative the less it is worth is kinda the easiest way to explain it.
Answer:
30
Step-by-step explanation:
Pythagorean theorem states that a^2 + b^2 = c^2
this theorem only works on triangles with an angle of 90 degrees or a right triangle.
18^2 + 24^2 = 900
the square root of 900 is 30
I did the square root of 900 because the square root is the 'opposite' of squaring which is what you need to do in order to find 'c' is the Pythagorean theorem. 'a' is 18, and 'b' is 24
Answer is 30
Answer:
The pooled estimate is given by the following formula:
![\hat p= \frac{x_1 +x_2 }{n_1 + n_2}](https://tex.z-dn.net/?f=%20%5Chat%20p%3D%20%5Cfrac%7Bx_1%20%2Bx_2%20%7D%7Bn_1%20%2B%20n_2%7D)
And replacing we got:
![\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435](https://tex.z-dn.net/?f=%20%5Chat%20p%3D%20%5Cfrac%7B42%2B45%7D%7B100%2B100%7D%3D%20%5Cfrac%7B87%7D%7B200%7D%3D%200.435)
Step-by-step explanation:
We have the following info given:
n1 = 100,
n2 = 100,
x1 = 42,
x2 = 45
The pooled estimate is given by the following formula:
![\hat p= \frac{x_1 +x_2 }{n_1 + n_2}](https://tex.z-dn.net/?f=%20%5Chat%20p%3D%20%5Cfrac%7Bx_1%20%2Bx_2%20%7D%7Bn_1%20%2B%20n_2%7D)
And replacing we got:

Answer:
x ≤ 17
Step-by-step explanation:
Pick up fee = 2.80
Cost per mile = 1.25
Total cost = $24.05
Number of miles ride, x
Pickup fee + mile per ride * number of ride ≤ total cost
2.80 + 1.25x ≤ 24.05
1.25x ≤ 24.05 - 2.80
1.25x ≤ 21.25
x ≤ 17
Number one of miles ride x ≤ 17
