The mean and the median are the same.<br> 2,3,4,5

Ber [7]

Step-by-step explanation:

$mean \: ( \bar x) = \frac{2 + 3 + 4 + 5}{4} = \frac{14}{4} = 3.5 \\ \\ median \: = \frac{3 + 4 }{2} = \frac{7}{4} = 3.5 \\ \\$

Thus, mean and median are same.

How many times greater was the temperature in Miami (45) than the lowest in San Diego (25)

Greeley [361]

Answer:

<em>The temperature in Miami is 9/5 times the temperature in San Diego.</em>

Step-by-step explanation:

<u>Ratios</u>

To compare the temperature in Miami (45) with the temperature in San Diego (25), we use the division or ratio between both numbers:

$\displaystyle \frac{45}{25}$

Simplify the fraction dividing by 5:

$\displaystyle \frac{9}{5}$

Since the relation between them is 9/5, it means the temperature in Miami is 9/5 times the temperature in San Diego.

tyrone opens an account at the local bank by depositing $50 of his birthday money. He continues to deposit $50 each month for 5

Pavel [41]

<u>Answer-</u>

<em>The amount will be </em><em>$8944.62</em><em> after 5 years.</em>

<u>Solution-</u>

We know that,

$\text{FV of annuity}=P[\dfrac{(1+r)^n-1}{r}]$

Where,

P = Payment = $50 monthly

r = rate of interest compounded monthly= $3\frac{1}{4}=3.25\%=0.0325$

n = number of period = 5 years = 5×12 = 60 months

Putting the values in the formula,

$\text{FV of annuity}=50[\dfrac{(1+0.0325)^{60}-1}{0.0325}]$

$=50[\dfrac{(1.0325)^{60}-1}{0.0325}]$

$=50[\dfrac{6.8140-1}{0.0325}]$

$=50[\dfrac{5.8140}{0.0325}]$

$=50\times 178.8923$

$=8944.62$

Therefore, the amount will be $8944.62 after 5 years.
