A professional athlete deposited an amount of money into a high-yield mutual fund that earns 14% annual simple interest. A secon

Kaylis [27]

Answer:

$1,200

Step-by-step explanation:

Let x be the amount of money deposited in the mutual fund. The interest earned by that investment can be determined as the amount deposited times the interest rate:

$I_{1} = x*0.14$

The value the second deposited can be determined as x+$2,400 and its interest earned is defined in the same manner as the first deposit's:

$I_{2} = (x+2400)*0.08$

The total interest on both investment equals the sum of both interests:

$456=I_{1}+I_{2}\\456=(x+2,400)*0.08 +x*0.14\\x=\frac{456-192}{0.22}\\ x=1,200$

$1,200 were invested in the mutual fund.

it costs $36.75 for 3 tickets to visit the science center. it costs $51 for 4 tickets to visit the zoo. which attraction will co

lord [1]

Find the cost for one ticket for the science center.

36.75 ÷ 3 = 12.25

Multiply the product with 12 to get the cost of 12 tickets.

12.25 × 12 = 147

Find the cost of 1 zoo ticket.

51 ÷ 4 = 12.75

Find the cost of 12 tickets by multiplying the product and 12

12.75 × 12 = $153

12 Science Center Tickets cost $147

12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.

153 - 147 = 6

The zoo only costs $6 more for 12 students.

So, you're answers are Zoo and $6

A researcher wishes to estimate, with 9999% confidence, the population proportion of adults who think Congress is doing a goo

jok3333 [9.3K]

Answer:

a: 1037 is the minimum sample size needed

b: 712 is the minimum sample size needed

Step-by-step explanation:

We need to use the formula for minimum sample size of a proportion when a sample proportion is known.

The level of confidence is 99%, which has a corresponding z-value of 2.575.

We know the desired error is 4%, or 0.04.

Part a: We have no prior estimate. See attached photo for calculation

Part b:

We know p-hat = 0.22. Therefore q-hat = 1 - 0.22 = 0.78

See the attached photo for the calculation of the minimum sample size
