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:

The first graph

Step-by-step explanation:

Slope intercept form is

y = mx + b

m is the slope

b is the y-intercept

3x + y = -2

subtract 3x from both sides

y = -3x - 2

Only the first graph has a negative slope and a y-intercept of -2

Answer:

a. 2

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Standard deviation is known to be 14.

This means that [tex]\sigma = 14[/tex]

Sample of 49

This means that [tex]n = 49[/tex]

The standard error of the mean is

[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{14}{\sqrt{49}} = \frac{14}{7} = 2[/tex]

So the correct answer is given by option a.

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)

- Use the distributive property to get 4c-12=8

-Divide both sides by 4 to get c-3 = 2

Step-by-step explanation:

- Use the distributive property to get 4c-12=8

[tex]4(c - 3) = 8 \\ 4 \times c - 4 \times 3 = 8 \\ 4c - 12 = 8[/tex]

Answer:4c-12=8

Step-by-step explanation:

4(c-3)=8

4xc-4x3=8

4c-12=8

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:

x - a

Step-by-step explanation:

The mean is calculated as

mean= [tex]\frac{sum}{count}[/tex]

         = [tex]\frac{x-3a+x-2a+x-a+x+x+a}{5}[/tex]

         = [tex]\frac{5x-5a}{5}[/tex]

         = [tex]\frac{5(x-a)}{5}[/tex]

         = x - a

Answer:

A) 4

Step-by-step explanation:

Area of a triangle formula:

A = 0.5bh

Given:

b = 4

h = 2

Work:

A = 0.5bh

A = 0.5(4)(2)

A = 2(2)

A = 4

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.

"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.

The formula which is utilized to find these values is provided below:

Answer:

C

Step-by-step explanation:

(x, y) 0 is x and 1 is y so that is exactly on the y axis

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:

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]
