Homer and Bart plan to buy one computer for $499.00 strictly for gaming
kati45 [8]

Answer:

Part A: T(x) = $49.99x + $499.00

Part B: $748.95

Part C: T(x) = $49.99x + $24.99y + $499.00

Part D: $773.93

Step-by-step explanation:

Part A:

Let x represent the amount of games bought. Let T(x) represent total cost.

T(x) = $49.99x + $499.00

Part B:

T(x) = $49.99(5) + $499.00

T(x) = $249.95 + $499.00

T(x) = $748.95

Part C:

Let y represent the amount of controllers bought.

T(x) = $49.99x + $24.99y + $499.00

Part D:

T(x) = $49.99(4) + $24.99(3) + $499.00

T(x) = $199.96‬ + $74.97 + $499.00

T(x) = $773.93

20 is 1/10 (one tenth) of what number?
NARA [144]

Answer:

20 is 1/10 of 200.

Step-by-step explanation:

100*(1/10) = 10

200*(1/10) = 20

Since 100 times 1/10 is 10, all you have to do is double it. So now, 200 times 1/10 is 20.

:) Hope this helps!

Construct a 95​% confidence interval to estimate the population mean using the data below. x overbarequals37 sigmaequals10 nequa
kap26 [50]

Answer:

With 95% confidence when n equals 44, the population mean is between a lower limit of 33.96 and an upper limit of 40.04

Step-by-step explanation:

Confidence Interval = mean + or - Error margin (E)

mean = 37

sd = 10

n = 44

degree of freedom = n - 1 = 44 - 1 = 43

t-value corresponding to 43 degrees of freedom and 95% confidence level is 2.0165

E = t × sd/√n = 2.0165×10/√44 = 3.04

Lower limit = mean - E = 37 - 3.04 = 33.96

Upper limit = mean + E = 37 + 3.04 = 40.04

95% confidence interval is between 33.96 and 40.04
