Answer:

Yes

Step-by-step explanation:

So permiter is two*lengths plus 2*width of a shape.

Area is the length times the width.

For examplel if a square has a length of 2, and a width of 3 the permiteter is:

2*2+3*3=

4+9

On the other hand, area would be:

2*3

I hope this helps!

Goshia [24]

"The graph shows the distribution of time (in hours) that teenagers spend playing video games per week. ", The statement that best describes the distribution is "The distribution is approximately Normal, with a mean of 14 hours and a standard deviation of 4" Option B.

This is further explained below.

<h3>What is Normal distribution?</h3>

Generally, Data closer to the mean tends to occur more often than data further from the mean, as shown by the normal distribution, also known as the Gaussian distribution. The normal distribution may be represented graphically as a "bell curve."

In conclusion, "the graph illustrates the distribution of the amount of time, in hours, that teens spend playing video games over the course of a week," The statement "The distribution is nearly normal, with a mean of 14 hours and a standard deviation of 4" is the one that gives the most accurate account of how the data was distributed.

Suppose C and D represent two different school populations where C > D and C and D must be greater than 0. Whitch of the foll

In-s [12.5K]

Answer:

A. (C+D)^2 is the largest expression

Step-by-step explanation:

Squaring Properties

The square of a number N is shown as N^2 and is the product of N by itself, i.e.

$N^2=N*N$

If N is positive and less than one, its square is less than N, i.e.

$N^2$

If N is greater than one, its square is greater than N

$N^2>N, \ for\ N>1$

We have the following information: C and D represent two different school populations, C > D, and C and D must be positive. We can safely assume C and D are also greater or equal than 1. Let's evaluate the following expressions to find out which is the largest

A. (C+D)^2

Expanding

$(C+D)^2=C^2+2CD+D^2$

Is the sum of three positive quantities. This is the largest of all as we'll prove later

B. 2(C+D)

The extreme case is when C=2 and D=1 (recall C>D). It results:

2(C+D)=2(3)=6

The first expression will be

(3)^2=9

Any other combination of C and D will result smaller than the first option

C. $C^2 + D^2$

By comparing this with the first option, we see there are two equal terms, but A. has one additional term 2CD that makes it greater than C.

D. $C^2 - D^2$

The expression can be written as

(C+D)(C-D)

Comparing with A.

$(C+D)^2=(C+D)(C+D)$

The subtracting factor (C-D) makes this product smaller than A which has two adding factors.

Thus A. is the largest expression

What is the perimeter?

tamaranim1 [39]

Answer:

21.3 unit

Step-by-step explanation:

$side CB=\sqrt{(7^{2})+(2^{2})} =\sqrt{53}\\side CA=\sqrt{(5)^{2}+(2^{2})} =\sqrt{29} \\side AB=\sqrt{(5^{2} )+(7^{2} )} =\sqrt{74}$

$Perimeter=\sqrt{53} +\sqrt{29} + \sqrt{74} =21.2676$ unit

Solve the inequality. 2(4 + 2x) ≥ 5x + 5? x ≤

murzikaleks [220]

Treat as an equality, except flip the sign direction when yo multiply or divide both sides by a negative number

first distribute
2(4+2x)>5x+5
distribute
8+4x>5x+5
minus 4x fro both sides
8>x+5
minus 5 from both sides
3>x
x<3

x is less than or equal to 3
