Answer:

The expected number of children to attend the concert  is 143.

Step-by-step explanation:

The total guest expected to attend the concert = 200

Here, Ratio of Adults: Children = 2: 5

Let us assume the common factor in the given ratio  = m

So, the expected number of adults to attend the concert  = 2 m

Also, the expected number of children to attend the concert  = 5 m

Number of (Adults + Children) attending concert  = 200

⇒ 2 m +  5 m = 200

or, 7 m = 200

or,  m = 200 /7 = 28.57

or, m  = 28.57

Now, the expected number of children to attend  = 5 m

= 5 x 28.57 = 142.85 ≈ 143

Hence, the expected number of children to attend the concert  is 143.

Given (x – 7)2 = 36, select the values of x.
aksik [14]

Answer:

x=1,13

Step-by-step explanation:

(x – 7)^2 = 36

Take the square root of each side

sqrt((x – 7)^2) = sqrt(36)

x-7 = ±6

x-7 = 6         x-7 =-6

Add 7 to all sides

x-7+7 = 6+7         x-7+7 = -6+7

x = 13                    x=1
