Answer:

i) number of transactions for the month of January = 4

number of transactions for the month of February = 4

number of transactions for the month of March = 4

number of transactions for the month of April = 4

ii) Mean of four months = -495.7 /4 = -123.93

Step-by-step explanation:

i) number of transactions for the month of January = 4

number of transactions for the month of February = 4

number of transactions for the month of March = 4

number of transactions for the month of April = 4

ii) January February March April

-38.50 250.00 -14.00 -86.80

126.30 -135.20 99.00 -570.00

429.40 35.50 -82.70 100.00

-265.00 -62.30 -1.50 -280.10

Total 252.20 88.20 0.80 -836.9

Total of four months = 252.2 + 88.20 + 0.80 - 836.9 = -495.7

Mean of four months = -495.7 /4 = -123.93

A small radio transmitter broadcasts in a 63 mile radius. If you drive along a straight line from a city 38 miles north of the t

olchik [2.2K]

Answer:

A signal from the transmitter will be picked up through out the 57.38 mile drive

Step-by-step explanation:

The radius of the transmitter = 63 miles

Therefore, since both the location 38 miles north and the location 43 miles east of the transmitter are within the the radius, the transmission of the transmitter will be received through out the straight line journey

The length of the travel path is given by;

Distance from 38 miles north of the transmitter to distance of 43 miles east of transmitter = $\sqrt{38^2+43^2} = 57.38 \, miles$ .

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint. How many pints of yellow paint will be needed i

katrin2010 [14]

Answer:

$1\frac{7}{8}$

Step-by-step explanation:

Given:

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint.

Question asked:

How many pints of yellow paint will be needed if the mixture contains one pint of blue paint ?

Solution:

We will easily find quantity of yellow paint, will be needed in the mixture, contains one pint of blue paint by using unitary method:

By using $\frac{2}{5} \ pint$ blue paint, yellow paint requires = $\frac{3}{4} \ pint$

By using 1 pint blue paint, yellow paint requires = $\frac{3}{4} \div\frac{2}{5} \\$

$=\frac{3}{4} \times\frac{5}{2} \\\\ =\frac{15}{8} \\\\ =1\frac{7}{8} \ pint$

Thus, $1\frac{7}{8}$ pint yellow paint requires in the mixture with one pint of blue paint.

A person invests $100,000 dollars at 8% for 10 years. How much money does the person have in their account if it is compounded..

krek1111 [17]

Answer:

a) $215,892.50

c) $220,803.97

e) $222,534.58

f) $222.554.09

Step-by-step explanation:

The compound interest formula is ...

FV = P(1 +r/n)^(nt)

where principal P is invested at annual rate r for t years, compounded n times per year. In this problem, you have P=100,000, r=0.08, t=10, and the only variable of interest is n.

When calculations are repeated, it is often convenient to let a calculator or spreadsheet do them. You only need to program the formula once, then use it for the different values of the variable of interest. Most spreadsheets have this formula built in, so you don't even need to program it.

For continuous compounding, the formula is ...

FV = Pe^(rt)

FV = 100,000e^(0.08·10) = 222,554.09

Answer:

y = 8x+0

Step-by-step explanation:

The slope is

m = (y2-y1)/(x2-x1)

= (-8-0)/(-1-0)

-8/-1

The y intercept is 0 since it goes through (0,)

The slope intercept form of the equation is

y = mx+b

y = 8x+0
