Answer:
This is binomial.
Here n = 5
p = 2/7
mean = np = 5*2/7 = 10/7 = 1.42857
standard deviation = sqrt(npq) = sqrt(5*2/7*5/7) = 1.01015
Step-by-step explanation:
Work Shown.
You're right but just to simplify your life, make the formula this...
A=2(wl+hl+hw)
w=width
h=height
l=length
Easy, just fill in the "variables."
Example,
l=2
w=2
h=2
Plug it in..
2(2*2+2*2+2*2)
2(4+4+4)
2(12)
24
Thus, your surface area example...
Easy.
Answer:
a ≤ 2
Step-by-step explanation:
Simplify both sides of the inequality
42a + 48 ≤ 132
Subtract 48 from both sides
42a + 48 − 48 ≤ 132 − 48
42a ≤ 84
Divide both sides by 42
42a/42 ≤ 84/42
a ≤ 2
Answer:
$5.61
Step-by-step explanation:
we know that
At a dinner, the meal cost $22 and a sales tax of $1.87 was added to the bill.
so
using a proportion
Find out how much would the sales tax be on a $66 meal
Let
x ----> the amount of sales tax on a $66 meal
