I think it might be 30 but I don’t know
I’m not sure if this is right but I tried...

The Equation you are going to use: P(event)=number of favorable outcomes/total number of possible outcomes

1. Equal to
The probability of rolling a 4 is 1/6. There is 1 favorable outcome and 6 possible outcomes. The frequency of rolling a 4 after 90 times is 15/90 which is equal to 1/6. Therefore equal to.

2. Greater than
The probability of rolling a number less than 4 is 3/6 or 1/2. After 90 times, the outcome was 46/90 which simplified is 23/45. Half of 45 is 22.5 and 23 > 22.5.

3. Less than
The probability of rolling a multiple of 3 is 2/6 or 1/3. After rolling the cube 90 times, the outcome was 24/90 which simplified is 4/15. 1/3 of 15 is 5. 4 < 5. Therefore, less than.

HELP PLEASE!!!
Which equation can be used to calculate the area of the shaded triangle in the figure below?


2(12 × 4) = 96 square feet
1 over 2.(12 × 4) = 24 square feet
2(12 + 4) = 32 square feet
1 over 2.(4 + 12) = 8 square feet

Answers

1 over 2.(4 + 12) = 8 square feet

1 over 2.(12 × 4) = 24 square feet

2(12 × 4) = 96 square feet

2(12 + 4) = 32 square feet

so the answer isn’t 32 it’s actually 24. because if you do the area of a rectangle with a width of 4 and a length of 12 you get 48 ft squared. the. divide that by 2 and you get 24 because half of a rectangle from one angle to the other makes a triangle meaning half of the rectangle. so half of 48 is 24

Answers

Answer:

C) 67.5 square feet

Step-by-step explanation:

the equation for finding the area of a triangle is height times the base divided by 2. so it would be 15/2 then multiplied by 9

Answer: 67.5 square feet

Area of triangle equation is :
(Base x height) /2

15 x 9 = 135

135/2= 67.5
