Answer:

lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²

curved surface area=2[area oftraingle]=2×1/2×4×3

=12cm²

now

total surface area=72cm²+12cm²=84cm²

volume of traingular prism=area of traingle ×length

=1/2×12×3.4×4=81.6cm³

Answer:

a) $2^{3}$

b) $2^{5}$

c) $2^{8}$

d) $\frac{5}{2^{3} }$

e) $2^{4} + 2^{3}$

Step-by-step explanation:

a) 8 = 2 x 2 x 2

b) 32 = 2 x 2 x 2 x 2 x 2

c) 256 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

d) 5 x 2^3 / 64 = 5 x 8 / 64

= 40/64

= 5/8

= $\frac{5}{2^{3} }$

e) 16 - (-2)^3 = 16 - (-8)

= 16 + 8

= $2^{4} + 2^{3}$

A study showed that 14 of 180 publicly traded business services companies failed a test for compliance with Sarbanes-Oxley requi

Vika [28.1K]

Answer:

The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 180, \pi = \frac{14}{180} = 0.0778$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0778 - 1.96\sqrt{\frac{0.0778*0.9222}{180}} = 0.0387$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0778 + 1.96\sqrt{\frac{0.0778*0.9222}{180}} = 0.1169$

The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).

Find QR. <br> A).12<br> B).-8<br> C).9<br> D).6

mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

$\sf 3 + 2x + 22 = x + 17$

$\sf 2x + 25 = x + 17$
$\sf 2x - x = 17 - 25$
$\sf x = - 8$

Now that we found x, let's find QR :-

QR = 2x + 22

$\sf QR = 2( - 8) + 22$
$\sf - 16 + 22$
$\sf 6$

Therefore, QR = 6 !!!
