Answer:
Because dividing is basically multiply by the inverse.
Step-by-step explanation:
Much like negating a number from a number is adding the later one to the flipped sign of the earlier number, dividing a fraction by a fraction means you multiply the later by the inverse of the earlier. To find the inverse of a fraction, you flip it upside down.
Answer:
-185.75297
Step-by-step explanation:
Solution:-
- We are testing whether the population mean u is equal to 100 as per claim.
Null hypothesis: u = 100
- Where a alternate hypothesis suggest that the population mean ( u ) may be lower:
Alternate hypothesis: u < 100
- We are given sample data parameters which are assumed to be normally distributed:
sample mean, x_bar = 9
sample standard deviation, s = 2.4
- A sample of n = 24 observation was taken from a population of ( N ) with unknown population standard deviation ( σ ).
- The conditions of standard normal distribution are no longer applicable i.e:
n = 24 < 30
unknown population standard deviation ( σ )
- We will model the sample using t-distribution with ( n - 1 ) = 23 degrees of freedom.
- The t-statistics of the sample mean x_bar can be determined from standard t-distribution:

- The t-test value for mean ( u ) is -185.75297
I think that the answer to this is 40 girls
24/3=8
8*5=40
hope this helps
If we already know that one side= 39 and the other is 56, a triangle must measure up to 180 so 39+56= 95.180-95= 85 m<c= 85.
to find the scale factor we need to compare the two sides the scale factor is 1/2
The squared term and the function are symmetrical about the value of x that makes (x+5)^2 = 0. That value is ...
D. x = -5
