Step-by-step explanation:

a=1/2 bh

1) 4*3=12/2=6

2) 8*5=40/2=20

3)15*6=90/2=45

Answer:

1) 6

2) 20

3) 45

Step-by-step explanation:

To find the area of a triangle, use the formula [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the base, and [tex]h[/tex] represents the height. In the first triangle, the base length is 4 and the height is 3, so the area is 6. In the second triangle, the base length is 5 and the height is 8, so the area is 20. In the third triangle, the base length is 15 and the height is 6, so the area is 45.

Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare.

Which equation will represent Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.

12.20h + 7.15 = E

12.20h - 7.15 = E

7.15h + 12.20 = E

7.15h - 12.20 = E

Answers

Answer:

Step-by-step explanation:

Answer:

E = 12.20(h) - 7.15

h = 6.82 hours

Given:

Pay hour = $12.20 per hour

Bus fare = $7.15

1.Equation:

Assume

She has work for "h" hours

Total earning = E

So,

E = 12.20(h) - 7.15

If,

Total earning = E = $90.45

So,

E = 12.20(h) - 7.15

90.45 = 12.20(h) - 7.15

h = 6.82 hours

1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answers

Answer:

Total cost of footpath = 528 m²

Step-by-step explanation:

Width of footpath is 2m.

Thus,

For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²

For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²

Total area = 112 + 64 = 176 m²

cost to tile foot path is $3 per square metres.

Total cost of footpath = 176 × 3

Total cost of footpath = 528 m²

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.

Answers

Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1

The expected value of the winnings from a game will be [tex]2.96[/tex] .

What is Probability ?

Probability is the ratio of the number of possible outcomes to the total number of outcomes.

we have,

Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]

Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]

So,

To find the expected value,

Now,

Multiply payout values with its probability and sum these values,

i.e.

Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]

[tex]=0+0.2+0.76+1+1[/tex]

Expected value [tex]=2.96[/tex]

Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .
