Answer:

0.194


Step-by-step explanation:

Probability that BOTH are democrats means probability of <u>"one being democrat"</u> AND <u>"another also being democrat"</u>.

The AND means we need to MULTIPLY the individual probability of a person being democrat.

Probability that a voter is democrat is 44% (0.44) -- stated in the problem


Now, Probability BOTH being Democrats is simply MULTIPLYING 0.44 with 0.44

0.44*0.44=0.1936

Rounded to nearest thousandth, 0.194

Last answer choice is correct.

The measures of the angles of △ABC are given by the expressions in the table. Angle Measure A ​ (4x−13)° ​ B 15° C (x+18)∘ What
mr_godi [17]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles given and equate to 180

4x - 13 + 15 + x + 18 = 180 ( simplify left side )

5x + 20 = 180 ( subtract 20 from both sides )

5x = 160 ( divide both sides by 5 )

x = 32

∠A = 4x - 13 = (4 × 32) - 13 = 128 - 13 = 115°

∠C = x + 18 = 32 + 18 = 50°

As a check : 115° + 15° + 50° = 180° ← correct

Based on the random sample of n=800 observations, we have obtained a sample proportion p(bar =0.44. the goal is to test: h(0: p?
uysha [10]
<span>The standard error of a distribution of sample proprtions is defined as the standard deviation of the distribution and is symbolized by
SE(\hat{p})
and is calculated by the formula
SE(\hat{p})= \sqrt{ \frac{p(1-p)}{n} }</span>.

Given a <span>random sample of n = 800 observations and a sample proportion p = 0.44.

To test:
H_0:\hat{p}\ \textgreater \ 0.48 \\ H_a:\hat{p}\ \textless \ 0.48

The standard error rounded to four decimal places is given by:
SE(\hat{p})= \sqrt{ \frac{0.44(1-0.44)}{800} } \\  \\ = \sqrt{ \frac{0.44(0.56)}{800} } = \sqrt{ \frac{0.2464}{800} }  \\  \\ = \sqrt{0.000308} =\bold{0.0175}</span>
