Answer: 52.5cm²

Step-by-step explanation:

Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.

To work out the area of the rectangle you would have to do 8x5=40.

To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.

Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5

To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²

Hope this helps :)

You randomly select an integer from 0 to 9 (inclusively) and then randomly select and integer from 0 to 7 what is the probabilit
mezya [45]
<h3>Answer:  1/80</h3>

Reason:

Set A = {0,1,2,3,4,5,6,7,8,9}

Set B = {0,1,2,3,4,5,6,7}

The probability of getting a "2" from set A is 1/10 since there is one copy of "2" that we want out of ten values total.

The probability of getting a "2" from set B is 1/8 for similar reasoning. This time there are eight numbers in this set.

Multiply those fractions mentioned (1/10)*(1/8) = 1/80

This fraction converts to the exact decimal value of 0.0125, meaning there's exactly a 1.25% chance of getting "2" twice in a row.
