<h3>Answer: Choice J (lower right corner)</h3>

-20 and -7 are in circle A, but outside circle B

0, 9, 81 are in circle B

=====================================================

Explanation:

The set of whole numbers is

{0, 1, 2, 3, 4, ...}

While the set of integers is

{ ..., -3, -2, -1, 0, 1, 2, 3, ... }

The difference is that integers involves negative numbers.

-----------------

The upper left corner is incorrect because the "0" should be in set B since 0 is also a whole number. The lower left corner is also ruled out because of this reason.

The upper right corner (choice H) is incorrect as well because 10 and 46 are whole numbers also, so they belong in set B which is a better description/place for them.

So basically the numbers 0,1,2,3,... go in circle B. The negatives of those values will go in circle A, but outside circle B. Only choice J describes this kind of situation.

Suppose that 20% of the residents in a certain state support an increase in the property tax. An opinion poll will randomly samp
zepelin [54]

Answer:

C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.

Step-by-step explanation:

Given that 20% of the residents in a certain state support an increase in the property tax.

Sample size = 400

We want the sample proportion to be within 0.04 of the true proportion (i.e., between 0.16 and 0.24)

i.e. margin of error <0.04

Std error of sample = \sqrt{\frac{pq}{n} } =\sqrt{\frac{0.2(0.8)}{400} } \\=0.02

Critical value = margin of error/ std error = \frac{0.04}{0.02} \\=2

We know z value for 95% two tailed roughly equals 2.

Hence 95% confidence is right.

C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.

Find the value of x​
vodka [1.7K]

Answer:

x = 70

y = 110

z = 30

Step-by-step explanation:

all triangles add up to 180

30 + 80 = 110

180 - 110 = 70

x = 70

30 + 40 = 70

70 + 80 = 150

180 - 150 = 30

z = 30

40 + 30 = 70

180 - 70 = 110

y = 110

enot [183]
To answer this item, we let x and y be the amounts (in mL) of the red and the brown dyes, respectively. The equations that would allow us to answer the question are,
                               x + y < 200
                                  
                                    x ≤ 2y
The values of x and y in the inequalities are therefore 133.33 mL and 66.67 mL.
