raketka [301]

Answer:

j = 21 and n = 14

Step-by-step explanation:

we have the equations:

6j + n/3 = 134

j/3 + n = 31

54j + 3n = 1206

j + 3n = 93

53j = 1113

j = 21

(21)/3 + n = 31

7 + n = 31

n = 14

SOMEONE HELP ASAP WHATS THE MISSING ANGLE
Lapatulllka [165]

Answer:

130

Step-by-step explanation:

? is an exterior angle of a triangle

An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )

That being said the missing angle = 95 + 35

95 + 35 = 130

Hence, the answer is 130

Tori took out A $350,000 loan in order to purchase a house. She has to pay an interest of 5.2% over 35 years. how much interest
Dmitrij [34]

Hello from MrBillDoesMath!


Answer:

Interest paid = $ 1,713,568.73

Monthly p[payment = $4913.25


Discussion:

From the "compound interest formula:

A = final amount

P = Initial amount (Principal)

r = yearly interest rate

n = number of years of accumulation.


In our case,

A = 350000( 1 + .052)^35 =

      350000 (5.90)  =                  (approx)

      $2,063,568.73

Interest =  $2,063,568.73 - 350000 =  $ 1,713,568.73


There are 35 *12 = 420 months in 35 years. So the monthly payment would be   ($2,063,568.73 / 420)  = $4913.25



Thank you,

MrB

Suppose the population of all public universities shows the annual parking fee per student is $110, with a standard deviation of
vampirchik [111]
The probability would be 0.9738.

We first find the z-score for each end of this interval:

z = (x-μ)/(σ/√n) = (100-110)/(18/√49) = -10/(18/7) = -3.89

z = (x-μ)/(σ/√n) = (115-110)/(18/√49) = 5/(18/7) = 1.94

Using a z-table (http://www.z-table.com) we see that the probability that a score is less than the first z-score is 0.  The probability under the curve to the left of, less than, the second z-score is 0.9738.  Subtracting these we find the area between them:
0.9738 - 0 = 0.9738.
