OLga [1]

Answer = 48 blue counters

———————————————

There are originally 18 red and 48 blue.

The ratio of 3:8 is multiplied by six

3 x 6 = 18
8 x 6 = 48

Take out two red

18 - 2 = 16

The ratio 16:48 (divide by 3) simplifies to 1:3
so it fits.

HACTEHA [7]

Answer: $56.20

Step-by-step explanation:

Both the tax and the tips will be based on the total cost:

Tip = 43.57 * 20%

= $8.71

Tax = 43.57 * 9%

= $3.92

Total = Cost + Tip + Tax

= 43.57 + 8.71 + 3.92

= $56.20

Area And Volume PLS HELP

Ivahew [28]

Answer:

Area of Top Bottom- L x W = Area so 8 x 5= 40 sq ft

Area of Front Back- L x W = Area so 3 x 8 = 24 sq ft

Area of Left side/ Right side L x W = Area so 3 x 5 = 15

Total Surface Area- X + Y + Z = Total SA so 40 + 24 + 15 = 79

Volume- L x W x H = Volume so 8 x 5 x 3 = 120 cubic feet

Step-by-step explanation:

L being length

W being width

H being Height

If P(A)=.55, P(B)=.32 And P(AuB)=.70,

son4ous [18]

Answer:

A. 0.5313

B. 0.15

Step-by-step explanation:

Given:

$P(A)=0.55\\ \\P(B)=0.32\\ \\P(A\cup B)=0.70$

First , use formula

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

to find $P(A\cap B):$

$0.70=0.55+0.32-P(A\cap B)\\ \\P(A\cap B)=0.55+0.32-0.70=0.87-0.70=0.17$

A. Use formula

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}\\ \\P(A|B)=\dfrac{0.17}{0.32}=\dfrac{17}{32}=0.53125\approx 0.5313$

B. Use formula

$P(A'|B)=P(B)-P(A\cap B)=0.32-0.17=0.15$
