Answer:

Perimeter = 30 cm

Step-by-step explanation:

10 cm x 3 = 30 cm

the required perimeter of the given rectangle is 30 cm.

Perimeter is the measure of the figure on its circumference.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Here,
The length of a rectangle is 10 cm, which is 1/3 of it's perimeter.
Length = 1/3 of perimeter
10 = 1/3 perimeter
perimeter = 3 × 10
perimeter = 30 cm

Thus, the required perimeter of the given rectangle is 30 cm.

Answer:

standard deviation=4.472

variance=8.94437

The variance and standard deviation of the sample with data values of 7, 19, 8, 15, and 11 are 25 and 5 respectively.

A variable's value change could be accompanied by changes in other, related variables in a variety of ways. Variation refers to the relationship between the change in a variable's value when the values of the linked variables change.

Given:

The sample data = 7, 19, 8, 15, 11,

Calculate the Variance by the following formula,

Variance = Σ(xⁿ -m)² / t -1

Here x is the value of observation, m is the mean, and t is the total no of data.

For mean = (7+19+8+15+11) / 5

m = 12

Now substitute the values in the variation formula,

Variance = (12-7)²+(12-19)² + (12-8)² + (12-15)² +(12-11)² / 5-1

Variance = (25 + 49 + 16 + 9 + 1) /4

Variance = 25

And for deviation = [tex]\sqrt{variance}[/tex]

Deviation = [tex]\sqrt{25}[/tex]

Deviation = 5

Therefore, the variance and standard deviation of the sample with data values of 7, 19, 8, 15, and 11 are 25 and 5 respectively.

Answer:

3 dollars and 9 cents.

Step-by-step explanation:

From the question given above, the following data were obtained:

Total amount = 20 dollars

Amount for gift A = 9 7/10 dollars

Amount for gift B = 6 2/5 dollars

Amount for gift C =?

The amount of money she has left for gift C can be obtained as follow:

A + B + C = 20

9 7/10 + 6 2/5 + C = 20

Change to improper fraction

97/10 + 32/5 + C = 20

(97 + 64)/10 + C = 20

161/10 + C = 20

Collect like terms

C = 20 – 161/10

C = (200 – 161)/10

C = 39/10

Change to mixed fraction

C = 3 9/10 dollars

C = 3.9

C = 3 dollars and 9 cents

Therefore, Kathy had 3 dollars and 9 cent for gift C

B. Independent-samples t test

Step-by-step explanation:

The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.

Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.

Thus, the best test to use in this case will be the Independent-samples t test

Answer:

57

Step-by-step explanation:

Hello There!

complementary angles add up to equal 90

So to find the measure of angle 2 we subtract the given angle (33) from 90

90-33=57 so the measure of angle 2 = 57

Answer: 57°

Complementary Angles add up to 90°

Since we already have 33°, we need to find the other half.

90 - 33 = 57

It'll be 57°

Answer:

The third response

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

It cannot be Option A because the values are halve and there is nothing to distribute to them to make the values equal.

It's not option C because if you distribute 2y to each term in the parenthesis

you get -4[tex]y^{5}[/tex]  + 6y³  + 4y².   But where is the 8y² and -2y?

While Option B is equivalent, you can factor it out more and find the common factor of -2 to distribute among them as shown in option D

It is option D because distributing the -2y to each term solves to

-4[tex]y^{5}[/tex]  + 6y³   +  8y²  -2y.

Answer:

The equation is: [tex]800.5 + 45.25p \leq 1479.25[/tex]

The team can bring at most 15 players to the tournament.

Step-by-step explanation:

They rented a bus for $800.50 and budgeted $45.25 per player for meals.

This means that the cost for bringing p players is given by:

[tex]C(p) = 800.5 + 45.25p[/tex]

Members of a baseball team raised $1479.25 to go to a tournament.

This means that:

[tex]C(p) \leq 1479.25[/tex]

So

[tex]800.5 + 45.25p \leq 1479.25[/tex]

[tex]45.25p \leq 1479.25 - 800.5[/tex]

[tex]p \leq \frac{1479.25 - 800.5}{45.25}[/tex]

[tex]p \leq 15[/tex]

The team can bring at most 15 players to the tournament.

Answer:

25 cm^2/sec

Step-by-step explanation:

I my understanding of the question.  It doesn't matter what the area of the square is currently is, for example if the area is 25 cm^2, 36 cm^2 or 49cm^2, the rate will ALWAYS increase by rate squared.

      rate(a)  x  rate(b)  =  rate(area)           in this case rate(a) = rate(b)

        (5 cm^2/s) (5 cm^2/s)  = 25 cm^2/s

Answer:

the pipe is 39.1 yards long.

Step-by-step explanation:

you would use pythagorean theorem (a²+b²=c²). plug the 25 in to the a² and plug the 30 in to the b² and figure out c² (it would look something like this 25²+30²=c²). to do that you need to square the 25² and the 30². the 25² would turn out to be 625 and the 30² would be 900 you would add them and get 1525. then you would squareroot 1525(

[tex] \sqrt{1525} [/tex]

) and get 39.05 and round it up and get 39.1 yards. dont forget to put the mesurements down
