The Probability distribution table shows the proportion of people living in five different regions of a city. What is the probability that a person chosen at random, who lives in the city, lives in the central or north region.

Answer:

The critical value tα/2 that corresponds to a​ 98% confidence level with 1000 degrees of freedom is 2.33.

Step-by-step explanation:

From the question we are told that

   The critical value is  [tex]t_{\frac{\alpha }{2} } = 2.33[/tex]

From the student's t distribution table the probability of     [tex]( t > 2.33)[/tex] at a degree of freedom of  1000 is  

        [tex]\frac{\alpha }{2} = (t > 2.33 ) = 0.01[/tex]

Hence the level of significance is mathematically evaluated as

        [tex]\alpha = 2 * 0.01[/tex]

=>    [tex]\alpha = 0.02[/tex]

Generally the confidence level  is mathematically represented as

      [tex]C = 1- \alpha[/tex]

=>  [tex]C = 1- 0.02[/tex]

=>  [tex]C = 0.98[/tex]

Converting to  percentage

=>  [tex]C = 0.98 * 100[/tex]  

=>  [tex]C = 98\%[/tex]  

Answer:

a. 0.45. , 0.54. , 5.04 is the answer

Answer:

a

Step-by-step explanation:

It's a because it starts with 0.45 (the least because if its just 45 than thats less than 54) and the greatest is 5.04 (you can think of them as 45, 54, and 504 but DON'T AVTUALLY DO THAT IN MATH).

Answer:

x = -6

Step-by-step explanation:

2x + 4 = -8

Subtract 4 from both sides, -8 - 4 is -12

2x = -12

Divide 2 from both sides

x = -6

Answer:

1) 1500 litres

2)Remainder = 3

3)7 apples

4)50 glasses

Step-by-step explanation:

1) We are told that a leaking faucet wastes about 3 liters of water per day.

Now, if 500 faucets are repaired, it means total number of litres saved per day = 500 × 3 = 1500 litres

2) We are told that the quotient is 25 and the divisor is 14. the dividend is 353.

Now, the quotient multiplied by the divisor should give us the dividend. Otherwise, we subtract the value we get from the dividend to get the remainder.

Thus:

Quotient × divisor = 25 × 14 = 350

This is not equal to the dividend.

Thus the remainder is;

353 - 350 = 3

Remainder = 3

3) We are told Isaiah had 63 apples.

If he divided the 63 apples among his 9 friends evenly, it means the number of apples received by each of his friends is gotten by Dividing the total number of apples by the number of friends. This gives; 63/9 = 7 apples

4) We are told Nancy needs 5 oranges to make a glass of orange juice.

Now, Nancy has 250 oranges. This means that the number of glasses of orange juice she can make is; 250/5 = 50 glasses

Answer:

Yes, because BC is perpendicular to AB, and ABCD is a parallelgram.

Yes the parallelogram is a rectangle.

The distance between coordinate P(x1 , y1) and coordinate Q(x2 , y2) is calculated using the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]

Given:

ABCD is parallelogram, so its opposite sides are equal in length.

i.e., AB= CD and AD= BC

Now,

d=√(8−0)²+(4−8)

d=√(8)²+(−4)²

d=√64+16

d=√80

d=√(−6−2)²+(−4−(−8))²

d=√(−8)²+(4)²

d=√64+16

d=√80

so, AB = CD

Similarly, AD= BC = √180

Hence, a quadrilateral whose opposite side are equal called as rectangle.

Answer:

The answer is 5.

62 is half of 124

124 is one less than 125

The cube root of 125 is 5.

That is... 5 times 5 times 5 equals 125, since, 5 times 5 equals 25; and, 25 times 5 equals 125.

Answer: 26.7

First, you must remove the percentage sign, then you will get a equivalent decimal.

When we remove the % sign, we get 26.7.

The answer is 26.7. Hope this helps!

It is found that 26.7% as an equivalent decimal is 0.267.

LEt the value of which a thing is expressed in percentage is "a' so the percent that considered thing is of "a" is b%

However percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

To convert 26.7% to an equivalent decimal, we simply divide it by 100:

26.7% ÷ 100

26.7/ 100 x 100 = 0.267

Therefore, WE can conclude that 26.7% as an equivalent decimal is 0.267.

Answer:

Step-by-step explanation:

Answer:

Gross income = $38500

Adjusted gross income = $35800

Taxable income = $13000

Step-by-step explanation:

1. Gross income = wages + interest received

Gross income = $36,300 + $2200

Gross income = $38500

2. Adjusted gross income = Gross income - adjustments

Adjusted gross income = $38500 - $2700

Adjusted gross income = $35800

3. Taxable income = adjusted income - (exemption + deductions)

Taxable income = $35800 - ($4050 + $6300 + $7800 + $2900 + $1750)

Taxable income = $35800 - $22800

Taxable income = $13000

Answer:

The distance from John's house to Bill's house is 5 units

Step-by-step explanation:

John's house is located at the point (-5,7) and Bill's house is located at (-2,3) in a map of the town of Springville.

We need to find the distance from John's house to Bill's house. We use the formula of the distance between two points:

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]

Applying the formula:

[tex]d=\sqrt{(-2+5)^2+(3-7)^2}[/tex]

[tex]d=\sqrt{3^2+4^2}[/tex]

[tex]d=\sqrt{9+16}=\sqrt{25}[/tex]

d=5

The distance from John's house to Bill's house is 5 units
