On a lunch counter, there are 3 oranges, 5 apples, and 2 bananas. If 3 pieces of fruit are selected, find the probability that 1

Answer:

$Probability = \frac{1}{24}$

Step-by-step explanation:

Given

$Oranges = 3$

$Apples = 5$

$Banana = 2$

$Total = 10$

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

$Probability = P(Orange) * P(Apple) * P(Banana)$

$Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}$

<em>The difference in the numerator is as a result of picking the fruit without replacement</em>

$Probability = \frac{30}{720}$

$Probability = \frac{1}{24}$

Logan and his friend went out to dinner and spent $18.50.They left a tip of $2.59.

maria [59]

To find this out, use a percent proportion, use cross products, and solve the equation.

$\frac{2.59}{18.50}= \frac{p}{100} \\ 18.50p=259 \\ \frac{18.50p}{18.50}= \frac{259}{18.50} \\ p=14$

So, the percent tip is 14%.

Find the area of the figure.

Studentka2010 [4]

Answer:

SOLVE FOR RECTANGLE

Area: lw (length times width)

rectangle: lw (6x6)

AREA=36in

SOLVE FOR TRIANGLE B

Area: A=hbxb/2

A=hb/b2=6·6/2=18

TRIANGLE B=18in

SOLVE FOR TRIANGLE A

Area: A=hbxb/2

The height looks half the height as the other triangle

A=hb/b2=3·4/2=6

TRIANGLE A=6in

{ADD}

36+18+6

TOTAL: 60in
