Answer:
0.5 is part of the confidence interval, and thus, it is reasonable to believe more than half of food delivery drivers eat some of the food they are delivering.
Step-by-step explanation:
95% confidence interval for the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
This means that we are 95% sure that the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
Is it reasonable to believe more than half of food delivery drivers eat some of the food they are delivering?
0.5 is part of the confidence interval, and thus, it is reasonable to believe more than half of food delivery drivers eat some of the food they are delivering.
Answer: Add all the absolute deviations and divide by number of swimmers.
Step-by-step explanation:
To find the mean absolute deviation of any data we need to follow the following steps:
- Start by finding the mean of the data set.
- Find the absolute value of the difference between each data value and the mean.
- Find the sum of the absolute values of the differences.
- Divide the sum of the absolute values of the differences by the number of data values.
We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."
check the picture below.
so the area of the rectangle is x*y.
the area of the triangle is (1/2)(w)(z).
if we subtract the area of the triangle, from the containing rectangle, we're in effect making a whole in the rectangle, as you see there in lower-right corner.
Answer:
(0, -3) and (4, 5)
Step-by-step explanation:
y = x² − 2x − 3
y = 2x − 3
2x − 3 = x² − 2x − 3
0 = x² − 4x
0 = x (x − 4)
x = 0 or 4
Answer:
A
Step-by-step explanation:
Given
x² + 3x - 18
Consider the factors of the constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3, since
6 × - 3 = - 18 and 6 - 3 = + 3, thus
x² + 3x - 18 = (x + 6)(x - 3) → A
