Answer:
f(-3)=56
Step-by-step explanation:
When evaluating a specific input for a function, you just plug that input in for x.
So in this case, f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(9)+6+5
f(-3)=45+6+5
f(-3)=56
(72/80)x90=81
Divide seventy-two by eight and multiply it Ninety.
<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>

Answer:
The answer for A is .
The answer for B is <em>4 cans. </em>
The answer of C is <em>$98.</em>
Step-by-step explanation:
A-
Multiply 2.5 by 3.5 and you'll get 8.75 Multiply 3.5 by 1.2 and you'll get 4.2; divide and your answer will be 2.1 Add to 8.75 Get 10.85 Subtract from area of door ( 3m because 1.5 times 2 is 3) and you'll get 7.85
B-
Divide 7.85 by 2.5 and you'll get 3.104; round that and you'll get 4 cans.
C-
Multiply the amount of cans (4) by 24.5. Do this and you'll get $98.
