(3b)^2c when b=3 and c=7

(3 * 3)^2 * 7
= (3^2)^2 * 7
= 3^4 * 7
= 81 * 7
= 567

k0ka [10]

Answer:

$273.38 per month

Step-by-step explanation:

Monthly Payment Formula

$\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}$

where:

PMT = monthly payment
P = loan amount
i = interest rate per month (in decimal form)
n = term of the loan (in months)

Given:

P = $19,500 - $4,000 = $15,500
i = 2.25% / 12 = 0.0225 / 12
n = 5 years = 60 months

$\implies \sf PMT=\dfrac{15500 (\frac{0.0225}{12})(1+\frac{0.0225}{12})^{60}}{(1+\frac{0.0225}{12})^{60}-1}$

$\implies \sf PMT=273.3788438$

$\implies \sf PMT=\$273.38$

The General Social Survey asked a large number of people how much time they spent watching TV each day. The mean number of hours

DerKrebs [107]

Answer:

Yes, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66

Step-by-step explanation:

H0 : σ² = 2.66²

H1 : σ² < 2.66²

X²c = (n - 1)*s² ÷ σ²

sample size, n = 40

Sample standard deviation, s = 1.9

X²c = ((40 - 1) * 1.9²) ÷ 2.66²

X²c = 140.79 ÷ 7.0756

X²c = 19.897

Using a confidence level of 95%

Degree of freedom, df = n - 1 ; df = 40 - 1 = 39

The critical value using the chi distribution table is 25.6954

Comparing the test statistic with the critical value :

19.897 < 25.6954

Test statistic < Critical value ; Reject the Null

Hence, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66
