.95
7/8= .875 so obviously .95 is bigger
Answer: (0.504, 0.556)
Step-by-step explanation:
Given : Sample size : n= 1005
Number of adults stated that they were worried about having enough money to live comfortably in retirement = 531
Then the proportion of adults stated that they were worried about having enough money to live comfortably in retirement :
Significance level :
Critical value :
The confidence interval for population proportion is given by :-
Hence, the 90% confidence interval for the proportion of adults who are worried about having enough money to live comfortably in retirement = (0.504, 0.556)
Answer:
$786
Step-by-step explanation:
50, 60, 72
find the difference between the first and second hour earnings to get 10.
get the difference of the second and third to get 12.
we realize that they are in increasing with even numbers from 10 going further, ie, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28....etc
to get the total earnings for the 24 hrs, you have to keep on adding the next even number till you reach the 24th hour
you will get $786.
Answer:
A. y=x-3
B.y=x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=x-3
Length(l)= 2w+6
Width(w)= w
Area(A)= 140 m²
Area= l*w
140 = l*w
140= (2w+6)w
140= 2w²+6w( divide each side by 2)
70= w²+3w
w²+3w -70= 0
(^^^^^^Factor out expression)
(w-7)(w+10)= 0 (set each expression equal to zero and use the positive answer as the value for "w"(because a negative width is impossible))
w-7=0
w=7m
w+10=0
w= -10m (Impossible for a physical measurement to negative: therefore This "w" value is incorrect)
Use w=7 to find "l"
l= 2w+6
l=2(7)+6
l=14+6
l=20 m
Answer:
The dimensions of a rectangle are length and by width. For this rectangle the dimensions are 20 meters by 7 meters.
(width= 7 meters)
(length= 20 meters)
