Answer:
area = 84 m²
Step-by-step explanation:
area = (1/2)(4)(3)(2) + (5)(6) + (6)(3) + (4)(6) = 84 m²
Answer:
The PMF of B is given by
P(B=0) = 0.7
P(B=1) = 0.16
P(B=2) = 0.08
P(B=3) = 0.04
P(B=4) = 0.02
Step-by-step explanation:
Let x denote P(B=1), we know that
P(B=0) = 1-0.3 = 0.7
P(B=1) = x
P(B=2) = x/2
P(B=3) = x/4
P(B=4) = x/8
Also, the probabilities should sum 1, thus
0.7+x+x/2+x/4+x/8 = 1
15x/8 = 0.3
x = 0.16
As a result, the PMF of B is given by
P(B=0) = 0.7
P(B=1) = 0.16
P(B=2) = 0.08
P(B=3) = 0.04
P(B=4) = 0.02
If he bought 4 hats for $5 each and he spent a total of $44, he spent $44 - $20 in shirts.
44 - 20 = 24
2 shirts for $24 is 1 for 12
$12 for each shirt
Hope it helps :)
Answer: The sales price is $13.78
The original price is $57.41. It is selling at 76% off.
First, we need to find the discount. To find the discount, we need to find out what is 76% of $57.41
-------------------------------------------------
Find discount
-------------------------------------------------
76% x $57.41 ← change the percentage to decimal
= 0.76 x 57.41
= $43. 63 (nearest hundredth)
Now that we know the discount, we can find the sales price by subtracting the discount from the original price.
-------------------------------------------------
Find sales price
-------------------------------------------------
$57.41 - $43.63 = $13.78
-------------------------------------------------
The sales price is $13.78.
