Answer:

The population standard deviation is 1.92.

Step-by-step explanation:

Population mean:

Sum of all values divided by the number of values. Thus:

[tex]M = \frac{2 + 3 + 5 + 7}{4} = 4.25[/tex]

Population standard deviation:

Square root of the division between the sum of the difference squared of each value and the mean, and the number of values. Thus.

[tex]S = \sqrt{\frac{(2-4.25)^2 + (3-4.25)^2 + (5-4.25)^2 + (7-4.25)^2}{4}} = 1.92[/tex]

The population standard deviation is 1.92.

The slope should be -1/2, because the line goes down 1 unit and then right 2 units.

Also it would be y = -1/2x+1 in y=mx+b.

Answer:

x ≥0

Step-by-step explanation:

Given the product:

√(5x)*√(x+3)

The function has to be defined if x ≥0

Hence;

√(5x)*√(x+3)≥0

Find the product

√(5x)(x+3)≥0

Square both sides

(5x)(x+3)≥0

5x≥0 and x+3≥0

x≥0/5 and x ≥0 - 3

x ≥0 and x ≥-3

Hence the required inequality is x ≥0

Answer:

A) 4

Step-by-step explanation:

Area of a triangle formula:

Step-by-step explanation:

Answer:

x = 11.5

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

x^2 + 8^2 = 14^2

x^2 + 64 = 196

x^2 = 196 - 64

x^2 = 132

x = [tex]\sqrt{132}[/tex]

x = [tex]2\sqrt{33}[/tex]

x = 11.5

Answer:

11.5

Step-by-step explanation:

Use the pythagorean theorem.

a^2 + b^2 = c^2

8^2 + b^2 = 14^2

64 + b^2 = 196

-64             -64

(radical) b^2 = (radical) 132

b = 11.5

Answer:

"Interval estimation" is the correct answer.

Step-by-step explanation:

Throughout the comparison to highlight estimates, the interval estimate would be the use of statistical analysis for calculating a range of potential measured values, which would be a continuous random variable.

Answer and explanation:

A. profit P as a function of x, the number of tickets sold

P(x)= total revenue - total cost

For 40000 tickets at $4

=40000×4-0.10×40000+$95000

=$160000-$99000

=$61000

For 35000 tickets at $5

= 35000×$5-0.10×35000+$95000

= $175000-$98500

= $76500

B. P has a downward slope like a demand curve. Increase in price equal to decrease in profit.

C. P(40000)= $4-$0.10+$95000/40000

= $4-$2.475

= $1.525

Price for 20000 tickets was not stated in question but feel free to use an arbitrary price(price should be higher than that for 35000 tickets and 40000 tickets)

0.20x + x = 18600

Answer:

28% off 160.00 is 115.20

The difference is 44.80

Step-by-step explanation:

One way is to multiply 160 by 28 percent, and then divide the answer by one hundred, then deduct that result from the original price.

Purchase Price:

$160

Discount:

(160 x 28)/100 = $44.80

Final Price:

160 - 44.80 = $115.20

Thus, a product that normally costs $160 with a 28 percent discount will cost you $115.20, and you saved $44.80.

You can also calculate how much you save by simply moving the period in 28.00 percent two spaces to the left, and then multiply the result by $160 as follows: $160 x .28 = $44.80 savings.

Furthermore, you can get the final price by simply deducting .28 from 1 and multiplying it by $160 as follows: (1 - .28) x $160 = $115.20 final price.

Answer:

160-44.8=115.2

Step-by-step explanation:

160 would be 100%

28%=x

[tex]\frac{160}{x} = \frac{100}{28}[/tex]

[tex]\frac{x}{160} =\frac{28}{100}[/tex]      x=44.8

28% of 160 would be 44.8

160-44.8=115.2

Answer:

54 cm^2

Step-by-step explanation:

side ( a ) = 3 cm

Formula : -

Surface area ( cube ) = 6a^2

Surface area ( cube )

= 6 x ( 3 )^2

= 6 x 9

= 54 cm^2

Answer:

54cm^2

Step-by-step explanation:

There are 6 sides in a cube. One of the sides should have the area of 9, because it's a cube and 3 * 3 is 9.

Considering that one side is [tex]9cm^{2}[/tex], the surface area should be 9 * 6, which is 54.

The surface area is 54cm^2.

Answer:

Distance between school and home = 105 miles.

Step-by-step explanation:

Let distance = D miles

Time to take walking/jogging, t1 = D/6 hours

Time by car, t2 = D/35 hours

Average time, t

= (t1+t2)/2

= D(1/6+1/35)

= (D/210)(35+6)

=41D/210 hours

Given t = t1-3 hours

41D/210 - D/6 = 3

Solve for D

41D/210 - 35D/210 = 3

(41-35)D/210 = 3

6D/210 = 3

D = 3*210/6 = 105 miles.

(Appreciate very much Diana's efforts to walk/job 105 miles to school, and we understand how lucky we are in most of Europe and North America)

Answer:

51/8

Step-by-step explanation:

LCM of 8, 4 and 2 = 8

7/4*2=14/8

Answer:

[tex]5\frac{1}{8}[/tex] hours

Step-by-step explanation:

First find the common denominator for all numbers.

The common denominator for all of those numbers will be 8.

[tex]1\frac{3}{4}=1\frac{6}{8}[/tex]

[tex]\frac{3}{2}[/tex]         The fraction is improper so we must simplify it!

[tex]1\frac{1}{2}[/tex]       Then convert it to a mixed number having a common denominator of 8!

[tex]1\frac{1}{2} =1\frac{4}{8}[/tex]  

Final Results: [tex]1\frac{6}{8} + 1\frac{4}{8} +1\frac{7}{8} =5\frac{1}{8}[/tex]

Final Answer: [tex]5\frac{1}{8}[/tex]
