The probability of a person being a supporter of the new community center is 56% or 0.56.

<h2 /><h2>Given to us</h2>
  • 56% of voters support funding a new community center
  • A surveyor randomly selects 75 voters and asks each voter if he or she is in favor of the center.

<h2>To find</h2>

the probability of a success for this binomial experiment.

We want to know the probability of a single success for this experiment. therefore,

x=1

As given to us that 56% of the voters support funding the new community center, there, the probability of a person being a supporter is 0.56.

p=0.56

Thus, the probability of a person being a supporter of the new community center is 56% or 0.56.

horsena [70]

Answer:

87.92 ft

Step-by-step explanation:

The circumference of a circle can be found using the formula: c = 2pi(r) OR c = pi(d).

r stands for the radius, d stands for the diameter. Because you're given the diameter of the circle, you can simply multiply 28 by pi (3.14), and you'll get the circumference!

How many years will it take each situation to double its money? Situation A: Matthew invests $5,000 in an account with a compoun
algol [13]

Answer:

Matthew's money will double fastest in 6 years.

Step-by-step explanation:

<u><em>The complete question is</em></u>

Answer the question for each scenario<u><em> by applying the rule of 72</em></u>. How many years will it take each situation to double its money? Situation A: Matthew invests $5,000 in an account with a compound interest rate of 12%. Situation B: Morgan invests $2,500 in an account with a compound interest rate of 8%. Situation C: Maysen invests $10,000 in an account with a compound interest rate of 4.5%. Whose money will double fastest?

we know that

The <u><em>Rule of 72</em></u> is a simple way to determine how long an investment will take to double given a fixed annual rate of interest. By dividing 72 by the annual rate of return.

so

Situation A: Matthew invests $5,000 in an account with a compound interest rate of 12%

\frac{72}{12}=6\ years

Situation B: Morgan invests $2,500 in an account with a compound interest rate of 8%.

\frac{72}{8}=9\ years

Situation C: Maysen invests $10,000 in an account with a compound interest rate of 4.5%

\frac{72}{4.5}=16\ years

therefore

Matthew's money will double fastest in 6 years.

-x -7y = 14<br> -4x -14y =28
koban [17]

Given:

\to \bold{-x -7y = 14}\\\\\to \bold{-4x -14y =28}\\\\

To find:

\bold{x \ and \ y}=?

Solution:

\to \bold{-x -7y = 14}..................... (i) \\\\\to \bold{-4x -14y =28} .................(ii)\\\\

Solving the equation (i):

\to \bold{-x -7y = 14} \\\\  \to \bold{-x=  14+7y} \\\\    \to \bold{x= - (14+7y)} \\\\

Putting the value of x into the equation (ii):

\to \bold{-4(-(14+7y)) -14y =28} \\\\\to \bold{4(14+7y) -14y =28} \\\\\to \bold{56+28y -14y =28} \\\\\to \bold{56+14y =28} \\\\\to \bold{28+14y =0} \\\\\to \bold{14y =-28} \\\\\to \bold{y =\frac{-28}{14}} \\\\\to \bold{y =-2} \\\\

Putting the value of y into the equation (i):

\to \bold{-x -7(-2) = 14}\\\\\to \bold{-x +14 = 14}\\\\\to \bold{-x  = 14-14}\\\\\to \bold{x  = 0}\\\\

So, the value of \bold{x=0 \ and\  y= -2}\\\\
