Solve 12x-5>-2 please

Stells [14]

Answer:

$x > \frac{1}{4}$

Step-by-step explanation:

$12x - 5 > - 2$

Lets add +5 in both the sides.

$= > 12x - 5 + 5 > - 2 + 5$

$= > 12x > 3$

Now lets divide 12 on both the sides.

$= > \frac{12x}{12} > \frac{3}{12}$

$= > x > \frac{1}{4}$

$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!

A major department store chain is interested in estimating the mean amount its credit card customers spent on their first visit

sergiy2304 [10]

Answer:

95% Confidence interval: (39.43, 61.58)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = $50.50

Sample size, n = 15

Alpha, α = 0.05

Sample standard deviation = 20

95% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 14 and}~\alpha_{0.05} = \pm 2.1447$

$=50.50 \pm 2.1447(\dfrac{20}{\sqrt{15}} ) \\\\= 50.50 \pm 11.0751 \\= (39.4249,61.5751)\\\approx (39.43, 61.58)$

95% Confidence interval: (39.43, 61.58)
