\huge \mathscr{\blue {\underline {\red{\underline{Answer :-}}}}}

\bf \frac{5}{2} x - 7 =  \frac{3}{4} x + 14

\bf \implies \:  \frac{5}{2} x -  \frac{3}{4} x = 14 + 7

\bf \implies \:  \frac{10x - 3x}{4}  = 14 + 7

\bf \implies \:  \frac{7}{4} x = 21

\bf \implies \: 7x = 21 \times 4

\bf \implies \: x =  \frac{21 \times 4}{7}

\bf \implies \: x = 3 \times 4

\bf \implies \: x = 12

25% of 400 is equal to 20% of What?
Bess [88]

Here is your answer:

First find 25% of 400:

  • 400/x=100/25
  • (400/x)*x=
  • (100/25)*x
  • x 400=4*
  • 400/4=x  
  • 100=x  
  • x=100

The answer is "500."

  • 100 ÷ 20%
  • 100 ÷ (20 ÷ 100) =
  • (100 × 100) ÷ 20 =
  • 10,000 ÷ 20 =
  • = 500

Hope this helps!

Suppose a baseball team has 14 players on the roster who are not members of the pitching staff. Of those 14 players, assume that
Nadusha1986 [10]

Answer: Our required probability would be 0.70.

Step-by-step explanation:

Since we have given that

Number of players = 14

Number of players have recently taken a performance enhancing drug = 3

Number of players have not recently taken a performance enhancing drug = 14-3=11

Number of members chosen randomly = 5

We need to find the probability that at least one of the tested players is found to have taken a performance enhancing drug.

P(Atleast 1) = 1 - P(none is found to have taken a performance enhancing drug)

So, P(X≥1)=1-P(X=0)

P(X\geq 1)=1-^5C_0(\dfrac{11}{14})^5\\\\P(X\geq 1)=1-(0.786)^5\\\\P(X\geq 1)=0.70

Hence, our required probability would be 0.70.

What is the answer please im so anyyoned its inquatiltys and greater than less than please help
Basile [38]
Equation: 50 is greater than or equal to 45 + .5(x)

x = amount of pictures you can send without going over your budget

subtract 45 from both sides. you are left with: 5 is greater than or equal to .5(x)

multiply both sides by 2. you are left with: 10 is greater than or equal to x

Answer: 10 is greater than or equal to x

The high school graduating class of 2010 was 260 people. Five years later the high school graduating class was 320 people. By ap
jeka94

Answer:

The high school graduating class changed by approximately 23%

Step-by-step explanation:

we have

The high school graduating class of 2010 was 260 people

Five years later the high school graduating class was 320 people.

we know that

260 people represent the 100%

so

The difference is (320-260)=60 people

using proportion

Find out what percentage represent 60 people

Let

x ----> the percentage that represent 60 people

\frac{260}{100\%}=\frac{60}{x}\\\\x= 100\%(60)/260\\\\x=23.1\%

therefore

The high school graduating class changed by approximately 23%
