Answer:
a. True
Question 13 of the attached image;
Step-by-step explanation:
Confidence interval, in statistics can be defined as the probability that a population parameter will fall between two set values( upper and lower bound) for a certain proportion of times. Therefore, there's 99% chance that the true difference in RDI levels between men and women is contained within the 99% Confidence interval shown in the previous questions.
It’s b what u need to do is 13x9 which is 117 then divide it by 2 which is 58.5
Answer:
f(x) = 11 - x
Step-by-step explanation:
We have to find a function that has a graph as x + y = 11.
Now, the equation given is
x + y = 11
⇒ y = 11 - x
So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x
So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
