0.84(because 20% of the observations are about 0.84)
You've found the 80th percentile! The 80th percentile of the standard normal distribution is 0.84. That's because 80% of the observations fall below 0.84. (Note: The 80th percentile of every normal distribution is 0.84 times the standard deviation above the mean.)
Answer:
perimeter is sum of all four sides; two of which are '4j' and other two are 60 inches each
Step-by-step explanation:
P= 2(4j) + 2(60)
We know perimeter is 400 inches
400 = 8j + 120
8j = 280
j = 35
Answer: Surface area= 54
Step-by-step explanation:
To find the surface area of a cube you do 6 times s^2
S is the side length. In this case that is 3 cm. S^2 is 9
So now you do 6 times 9, and that is 54.
So, the surface area is 54.
Answer:
$31.5
Step-by-step explanation:
X * 5% = $1.50
X = $1.50 / 5%
Or by using simple rule of three:
If 5% is $1.50
Then 100% is X
So you obtain = $30
Now you just need to sum The net prices and the taxes
Net + tax = Total Charge
$30 + $1.5 = $31.5
Answer: 30
We will 5x+3x=48 simplified it’s 8x=48 divide 8 from both sides and get x=6 plug it in
RS= 5(6)= 30
