Answer:
9
Step-by-step explanation:
Given that the sample size is 45 blocks
Let number of red blocks in the bag to be x
Then the probability of chosing a red block will be x/45
Given that the probability of choosing a red block is 1/5 then you can form the expression;
x/45 = 1/5 ---------------find the value of x by performing cross multiplication
5x=45*1
5x/5=45/5
x=9
Answer
Julia put 9 red blocks in the bag.
Answer:
(-1,4)
Step-by-step explanation:
mp=xi+xii/2,yi+yii/2
7+-9/2=-1
0+8/2=4
=(-1,4)
The next four terms in the sequence are a + 6, a + 10, a + 14, a + 18. This is because you are adding 4 to what is being done to “a” each time. If you look at the pattern, you’ll see that 4 is being added and the “a” stays the same.
Area = b*h and in some cases * 2 so you need to do this, 64*52 + 40*28= 4448 yd2
