Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)
Answer:
y = 2x + 10
Step-by-step explanation:
Find the slope:
12 - 2 / 1 - (-4)
10 / 5 = 2
Write in point-slope form:
y - 12 = 2(x - 1)
rearrange:
y - 12 = 2x - 2
y = 2x + 10
The answer is this: $3.60
4 x 10 = 40 - 0.4 = 3.6
It is asking you to move the right formula with its match.
Formula for a cylinder: π*R^2*HSo the first option goes to the first shape.Example:
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer.
Formula for a square: l*w*hSo the 4th option goes with the 2nd shape. Example: l=5 w=5 h=5
(Length * Width * Hieght)
5*5*5=125 for the answer.
Formula for a cone is: 1/3π*r^2*hSo the second option goes to the 3rd shape.
Example: r=3 h=11
π≈3.14
![\frac{1}{3} *3 ^{2} *11=33](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%2A3%20%5E%7B2%7D%20%2A11%3D33)
33 is your answer.
Formula for the pyramid would be: 1/3*b*hSo the 3rd option would go to the 4th shape.Example:
b=2 h=10
![\frac{1}{3} *2*10=6.666667](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%2A2%2A10%3D6.666667)
Rounded: 6.6
