Answer:
x = number of bicycles = 35
y = number of cars = 55
Step-by-step explanation:
Let
x = number of bicycles
y = number of cars
x + y = 80 (1)
2x + 4y = 270 (2)
From (1)
x = 80 - y
Substitute x = 80 - y into (2)
2x + 4y = 270 (2)
2(80 - y) + 4y = 270
160 - 2y + 4y = 270
- 2y + 4y = 270 - 160
2y = 110
y = 110/2
y = 55
Substitute y = 55 into (1)
x + y = 80 (1)
x + 55 = 80
x = 80 - 55
x = 35
x = number of bicycles = 35
y = number of cars = 55
Take LCD of 6 and 3 = 6 is the lcm
5/6 -2/6n
(5-2n)/6.
Now, what number can be multiplied to the right side of the equal sign to get the value of P
The answer is 1/6 as the left side is divided by 6, so multiply the right side by 1/6 to make it equivalent.
Answer:
0.60 > 0.50
Step-by-step explanation:
Given
Required
Represent using decimal number and compare
From the question, we understand that there are 100th grids;
So:
Comparing both decimals;
Since 0.60 is greater than 0.50, we have:
0.60 > 0.50

Answer:
-1.53 , 1.53
Step-by-step explanation:
It is basically asking you to find the percentiles. so for the bottom 6.3% you would type into your calculator 2nd, VARS, invNorm, area: .063, mean: 0, and Standard Deviation: 1 which gives you -1.53.
for the upper 6.3% you have to take 1-.063=.937 to get the upper percentile. now type into your calculator 2nd, VARS, invNorm, area: .937, mean: 0, and Standard Deviation: 1 which gives you 1.53.
I hope I helped :D
