Answer:

10 1/2

Step-by-step explanation:

3.5 can be converted to 35/10

1.5 can be converted to 15/10

2 can be converted to, well, 20/10

35/10 * 15/10 * 20/10 can be simplified into 35 * 15 * 20 / 10 * 10 * 10= 10500/1000= 105/10= 10 5/10= 10 1/2

Answer:

$\frac{ {7}^{4} ( - 2) {}^{4} {11}^{3} 6}{7 {}^{3} {2}^{2} {6}^{2} 11 {}^{2} } = \frac{7 \times {2}^{2} \times 11}{6} = \frac{308}{6} = \frac{154}{3} \\ \\ \frac{ {7}^{0} {12}^{0} {17}^{0} }{ {57}^{0} + ( {42}^{0} \times ( {13}^{0} ))} = \frac{1}{1 + 1} = \frac{ 1}{2}$

Answer:

$-0.061 < P_1 -P_2< 0.025$

Step-by-step explanation:

Give data:

$n_1 = 350$

$n_2 =250$

$x_1 = 23$

$x_2 = 21$

$\hat{P} 1 = \frac{x_1}{n_1} = \frac{23}{350} = 0.066$

$\hat{P} 2 = \frac{x_2}{n_2} = \frac{21}{250} = 0.084$

for 95% confidence interval

$\alpha = 1 - 0.95 = 0.05 and \alpha/2 = 0.025$

$z_{\alpha/2} = 1.96$ from standard z- table

confidence interval for P_1 and P_2 is

$\hat{P} 1 - \hat{P} 2 \pm z_{\alpja/2} \sqrt{\frac{\hat{P} 1(1-\hat{P} 1)}{n_1} +\frac{\hat{P} 2(1-\hat{P} 2)}{n_2}}$

$(0.066 - 0.084) \pm 1.96 \sqrt{\frac{0.066(1-0.066)}{350} +\frac{0.084(1-0.084)}{250}}$

$-0.018 \pm 0.043$

confidence interval is

$-0.018 - 0.043 < P_1 -P_2$

$-0.061 < P_1 -P_2< 0.025$

What is the area of this triangle in square inches?

adelina 88 [10]

The area of a triangle is found by multiplying the base by the height, then dividing that by 2:

Area = 10 * 7 = 70

70 / 2 = 35 square yards.

Which of the following statements are false?

VikaD [51]

well, a and d are true, and b is somewhat false...

angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90

c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one

so b and c may be true, im not sure

i know that a and d are true, therefore they are not the right answer
