If a 42.9 ft tall flagpole casts a 253.1 ft long shadow then how long is the shadow that a 6.2 ft tall woman casts?

blsea [12.9K]

We will have to use proportions:
$\frac{42.9}{253.1} = \frac{6.2}{x}$
Cross multiplying we get
$42.9x = 6.2 \times 253.1$
Now divide:
$x = \frac{6.2 \times 253.1}{42.9}$
Solve to tenths place we get
$x = 36.6$
The woman casts a 36.6 ft long shadow.

Aloiza [94]

Answer: B. 0.036

Step-by-step explanation:

Formula for standard error :

$SE=\sqrt{\dfrac{p(1-p)}{n}}$

, where p = Population proportion and n= sample size.

Let p be the population proportion of the people who favor new taxes.

As per given , we have

n= 170

$p=\dfrac{55}{170}\approx0.324$

Substitute these values in the formula, we get

$SE=\sqrt{\dfrac{0.324(1-0.324)}{170}}\\\\=\sqrt{0.00129}\\\\=0.0359165699921\approx0.036$

Hence, the standard error of the estimate is 0.036.

∴ The correct answer is OPTION B. 0.036

Answer:

2. Line RT = 11x - 17, Line PT= 5x + 13

11x - 17 = 5x + 13

-5x. -5x

6x - 17 = 13

+17. +17

6x= 30

÷6. ÷ 6

x = 5

(B). According to the rules of a parallelogram, if angle S is 50°, the angle on the same side will be supplementary to it. So, angle R equals 130° and angle Q is also 50°.
