Answer:

−35.713332 ; 0.313332

Step-by-step explanation:

Given that:

Sample size, n1 = 11

Sample mean, x1 = 79

Standard deviation, s1 = 18.25

Sample size, n2 = 18

Sample mean, x2 = 96.70

Standard deviation, s2 = 20.25

df = n1 + n2 - 2 ; 11 + 18 - 2 = 27

Tcritical = T0.01, 27 = 2.473

S = sqrt[(s1²/n1) + (s2²/n2)]

S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]

S = 7.284

(μ1 - μ2) = (x1 - x2) ± Tcritical * S

(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284

(μ1 - μ2) = - 17.7 ± 18.013332

-17.7 - 18.013332 ; - 17.7 + 18.013332

−35.713332 ; 0.313332

A car is advertised as $288/month for 72 months. What is the cost of the car?

viktelen [127]

Answer:

$20,736

Step-by-step explanation:

When these kind of advertisements are displayed,, it means the EMI cost per month shall be $288.

Since it provides the time period, that is 72 months,

Total cost of car in this case shall be $288 $\times$ 72 months = $20,736

Also, these include an interest factor, but overall it is = $20,736 only,

If one down payment for full price of the car is made the cost shall reduce by the interest amount, but since no interest rate is provided it shall be ignored.

Evaluate the piece-defined function for the given of x by matching the domain values with the range values

Elenna [48]

Answer:

The correct answer is:

(1) d

(2) b

(3) a

(4) c

(5) e

Step-by-step explanation:

The given problem is incomplete. Find the attachment of the full question.

According to the question,

(1)

By putting x = -2, we get

$f(x)=(-2)^3-5$

$=-8-5$

$=-13$

(2)

By putting x = 0, we get

$f(x)=(0)^3-5$

$=0-5$

$=-5$

(3)

By putting x = 3, we get

$f(x)=8$

(4)

By putting x = 9, we get

$f(x)=(2)^{9-7}$

$=(2)^2$

$=4$

(5)

By putting x = 11, we get

$f(x)=(2)^{11-7}$

$=(2)^4$

$=16$

Ask an expert 2+3/10X>=13/20 Solve for inequality Thanks!

dolphi86 [110]

Answer:

The answer is in the picture.

Step-by-step explanation:

$2+\frac{3}{10x}\geq\frac{13}{20} \\\\\frac{3}{10x}\geq\frac{13}{20} -2 \\\\\frac{3}{10x}\geq\frac{13}{20} -\frac{40}{20} \\\\\frac{3}{10x}\geq-\frac{27}{20} \\\\3\geq-\frac{27}{20}*10 x \\\\3\geq-\frac{270}{20} x\\\\3\geq-\frac{27}{2} x \\\\3*-\frac{2}{27} \leq x\\\\-\frac{6}{27} \leq x\\\\-\frac{2}{9} \leq x$

Also x cannot equal to 0 if you plug in into the original equation the answer is indefinite/not solution.
