Answer:
Step-by-step explanation:
Given that x = no of movies high school students watched is N(6.8, 1.8)
Sample size = 36 and hence std error = 1.8/6 = 0.3
(two tailed test)
Mean difference = 6.2-6.8 = -0.6
Test statistic z = -0.6/0.3= -2
p value = 0.02275
Since p <0.05 we reject H0.
There is evidence to show that college students watch fewer movies a month than high school students
Answer:
x = 5.4
Step-by-step explanation:
4/3 = 0.75
7.2*0.75 = 5.4
Answer:
No solution
Step-by-step explanation:
There is no option good for the two graphs.
I think simple vertical stretch or simple vertical compression will occur at the same side of axis, but |x| located at quadrant I and II while -1/2|x| located at quadrant III and IV.
The answer should be "reflect over the x axis and then vertical stretch"
Area of square base = 324 m²
Length of the square side = √324 = 18
The side of the square is the base of the triangle.
Area of triangle = (1/2)*base* height
135 = (1/2)*18* h
135 = 9h
135/9 = h
15 = h
height = 15 m
To get the height of the Pyramid, the height of the Triangle and half the length of the side of the square form a right angled triangle.
Hypotenus = 15
Half length of square = 18/2 = 9
Height of Pyramid = H
By Pythagoras' Theorem:
15² = H² + 9²
225 =H² + 81
H² + 81 = 225
H² = 225 - 81
H² = 144 Take square root of both sides
H = √144
H = 12
Height = 12 meters.
Option C.

Step-by-step explanation:
<u>Recursive sequence
</u>
In a recursive sequence formula, each term 
is computed as a function of one or more previous terms. In the formula
n is the number of the term we want to calculate. If n=8, then the formula becomes
We can see 
is the previous term. It means we need 
to be able to compute 
. But we also need 
to compute and so on until some known data is reached. The question provides five terms,
