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

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

sara making punch for her party her punch bowl holds 600 ounces for 80 servings of punch write and solve an equation to find how

nlexa [21]

There are 7.5 ounces in each serving

Solution:

Given that, Sara making punch for her party her punch bowl holds 600 ounces for 80 servings of punch

To find: Ounces of punch in each serving

From given,

Number of servings = 80

Ounces in bowl = 600 ounces

Then, Ounces of punch in each serving is found by dividing the ounces in bowl by number of servings

The formula used is:

$\text{ Ounces of punch in each serving } = \frac{\text{Ounces in bowl}}{\text{Number of servings}}$

Substituting the values we get,

$\text{ Ounces of punch in each serving } = \frac{600}{80}\\\\\text{ Ounces of punch in each serving } = 7.5$

Thus there are 7.5 ounces in each serving

Answer:

x = 8 and y = - 1

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (8, - 1 ) with x- coordinate 8, then

x = 8 ← equation of vertical line

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (8, - 1 ) with y- coordinate - 1, then

y = - 1 ← equation of horizontal line
