Of the 84 parents who attended a meeting at a school, 35 volunteered to supervise children during the school picnic and 11 volun
Tatiana [17]

Answer:

The number of parents who volunteered to bring refreshments is 16.

Step-by-step explanation:

The information provided is:

N = 84

n (S) = 35

n (S ∩ R) = 11

n (R) = 1.5 × n (S' ∪ R')

Compute the value of n (S ∪ R) as follows:

n(S\cup R)=n(S)+n(R)-n (S\cap R)\\\\n(S\cup R)=n(S)+[1.5(N-n(S\cup R)]-n (S\cap R)\\\\n(S\cup R)=n(S)+1.5N-1.5n(S\cup R)-n (S\cap R)\\\\2.5n(S\cup R)=n(S)+1.5N-n (S\cap R)\\\\2.5n(S\cup R)=35+(1.5\times84)-11\\\\2.5n(S\cup R)=150\\\\n(S\cup R)=\frac{150}{2.5}\\\\n(S\cup R)=60

Now compute the value of n (R) as follows:

n (R) = 1.5 \times  n (S' \cup R') \\\\n (R) = 1.5 \times  [N-n (S \cup R)]\\\\n (R) = 1.5 \times  [84-60]\\\\n(R)=16

Thus, the number of parents who volunteered to bring refreshments is 16.

Can somebody help me with this math problem?
Lelechka [254]

Answer:

B

Step-by-step explanation:

Solve each inequality separately

2x + 3 ≥ 7 ( subtract 3 from both sides )

2x ≥ 4 ( divide both sides by 2 )

x ≥ 2

or

2x + 9 > 11 ( subtract 9 from both sides )

2x > 2 ( divide both sides by 2 )

x > 1

x ≥ 2 satisfies the condition for both inequalities

Thus x ≥ 2 is the solution

Her average rate of the entire trip would be 2 hours since 12mph for 10 miles and 12 miles going 10mph would crossed each other out and have 10 miles go 10mph (1 hour) and 12 miles going 12mph(1 hour)
