The answer would need to involve the reduction of 10 gallons of water from the pool so options A, B and E. Although, using practicality, B would not be feasible as the it would take a Long time for 10 gallons of water to evaporate and it would be more practical to remove the water physically.

3. Two mathematicians are neighbors. Each owns a separate rectangular plot of land that shares a boundary and has the
Dvinal [7]

Answer:

  • shared short side: 10x +6
  • shared long side: 8x +6

Step-by-step explanation:

The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...

  4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common

If the long side (2x+1) was common, then the perimeter of the combined lot is ...

  4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common

Which value must be added to the expression x^2+12x to make it a perfect-square trinomial?
Studentka2010 [4]

Answer:

Add 36. The factored form is (x+6)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value to add to it divide 20 by 2 and square it.

12/2 = 6

6*6 = 36

This means c=36. The factored form is (x+6)^2.

When testing a claim that the majority of adult Americans are against the death penalty for a person convicted of murder, a rand
Black_prince [1.1K]

Using the z-distribution, it is found that the p-value is of 1.

At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:

H_0: p \neq 0.5

At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:

H_1: p > 0.5

The test statistic is given by:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

In which:

  • \overline{p} is the sample proportion.
  • p is the proportion tested at the null hypothesis.
  • n is the sample size.

In this problem, the parameters are: \overline{p} = 0.27, p = 0.5, n = 491.

Then, the value of the <em>test statistic</em> is:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

z = \frac{0.27 - 0.5}{\sqrt{\frac{0.5(0.5)}{491}}}

z = -10.19

Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.
