Answer:

Step-by-step explanation:

<h3>Mean, Median,mode</h3>

   \boxed{Mean = \dfrac{Sum \ of  \  all \ data}{number \ of data}}

              \sf = \dfrac{234 + 247 + 236+212+248+243+176+195}{8}\\\\= \dfrac{1791}{8}\\\\= 223.875

<h3>Median:</h3>

Arrange the numbers in ascending order.

  176 , 195 , 212 , 234 , 236 , 243 , 247, 248  

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

            \sf = \dfrac{234+236}{2}\\\\ =\dfrac{470}{2}\\\\= 235

Mode is the data which is occurring more number of times.

Range = maximum - minimum

           = 248 - 176

            = 72

Licemer1 [7]

Answer:

  Mildred is correct because she distributed 5 correctly

Step-by-step explanation:

We cannot tell exactly which solution goes with which student, but we believe you are saying ...

Mildred’s Solution:

  5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth)

  = negative 10 minus StartFraction 5 over 4 EndFraction

  = negative 11 and one-fourth

This solution describes the correct distribution of 5. Whoever it belongs to gave the correct solution.

Joshua invested $750 in an account paying an interest rate of
Maslowich
Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.
Step-by-step explanation:
Giving the following information:
Joshua:
Initial investment (PV)= $750
Interest rate (i)= 0.0341/4= 0.008525
Number of periods (n)= 18*4= 72 quarters
Josiah:
Initial investment (PV)= $750
Interest rate (i)= 0.0285
Number of periods (n)= 18 years
To calculate the future value of each one, we need to use the following formula:
FV= PV*(1 + i)^n
Joshua:
FV= 750*(1.008525^72)
FV= $1,381.98
Josiah:
FV= 750*(1.0285^18)
FV= $1,169.74
Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

What initial investment must be made to accumulate $60000 in 17 years if the money is invested in a mutual fund that pays 12% an
mars1129 [50]

$7881.18

Step-by-step explanation:

   Let the initial Investment be P_{0}. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.

   As the annual interest rate is 12%, the monthly interest rate is 1%.

Since this is a compound interest problem, the total amount can be modeled as follows: P(t)=P_{0}(1+\frac{i}{100})^{t}

Here i is the interest rate, i.e 1, and t is the number of time periods, i.e 17\textrm{ years x }12\frac{\textrm{months}}{\textrm{year}}= 204\textrm{ months}

60,000=P_{0}\textrm{ x }(\frac{101}{100})^{204}

P_{0}=7881.18

∴ Initial Investment = $7881.18

Karolina [17]

Complete question :

At camp in Green Bay, Wisconsin, 7/9 of the participants were from Wisconsin. Of that group 3/5 were 12 years old. What fraction of the group was from Wisconsin and 12 years old?

Answer:

7/ 15

Step-by-step explanation:

Fraction from Wisconsin = 7/9

Fraction who are 12 years old = 3/5

Fraction who are from Wisconsin and 12 years old

(Fraction from Wisconsin * Fraction who are 12 years old)

(7 / 9 * 3/ 5)

= (7 * 3) / (9 * 5)

= 21 / 45

= 7 / 15
