Answer:

87/100

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are

2

numbers to the right of the decimal point, place the decimal number over

10

2

(

100

)

. Next, add the whole number to the left of the decimal.

Step-by-step explanation:

The marginal totals are the sum of each row and column.

For example, the total number of sophomores is 120 + 302 = 422.

See picture of table with marginal totals filled in.

Answer:

x - 9

Step-by-step explanation:

First, distribute:

-3x - 9 + 4x

Then, simplify (add up x):

x - 9

And we're done ^^

Answer:

-3x -9 +4x

-3x + 4x - 9

x - 9

The answer is x - 9

you multiply -3 by x - 3

And there you go .

Answer:

420.7

Step-by-step explanation:

8p + 5r = q

We have to isolate the variable  p. Let's begin by subtracting 5r from both sides.

8p = q - 5r

Divide both sides by 8

p = [tex]\frac{q - 5r}{8}[/tex]

[tex]8p + 5r = q[/tex]

Subtract 5r on both sides of the equation.

[tex]8p = - 5r + q[/tex]

Divide both sides of the equation by 8.

[tex]p = \frac{ - 5r + q}{8} [/tex]

Answer: If they start running at the same time, then it will take 30 minutes until they complete a lap together.

Step-by-step explanation:

Given:  Stephanie can run one lap around a track in 5 minutes. Lisa can run one  lap in 6 minutes.

If they start running at the same time, then the time they will take to complete a lap together = LCM (5,6)

prime factorization: 5=5   , 6 =2 x 3

So, LCM(5,6) = 5 x 2  x 3 = 30

Hence, it will take 30 minutes until they complete a lap together.

Given:

Nancy decides to roll a dice three times.

To find:

The probability that she will roll all even numbers.

Solution:

If a dice is rolled, then the possible numbers are

Total number = {1,2,3,4,5,6} = 6

Even numbers = {2,4,6} = 3

Odd numbers = {1,3,5} = 3

Probability of getting an even number [tex]=\dfrac{\text{Even number}}{\text{Total numbers}}[/tex]

[tex]P(\text{Even})=\dfrac{3}{6}[/tex]

[tex]P(\text{Even})=\dfrac{1}{2}[/tex]

So, probability of getting all even numbers is

[tex]P(\text{All even})=P(\text{Even})\times P(\text{Even})\times P(\text{Even})[/tex]

[tex]P(\text{All even})=\dfrac{1}{2}\times \dfrac{1}{2}\times \dfrac{1}{2}[/tex]

[tex]P(\text{All even})=\dfrac{1}{8}[/tex]

Therefore, the required probability is [tex]P(\text{All even})=\dfrac{1}{8}[/tex].

The probability that Nancy will roll all even numbers will be:

"[tex]\frac{1}{8}[/tex]".

According to the question,

Number of times dice rolled = 3

Total numbers = {1, 2, 3, 4, 5, 6}

                        = 3

Even numbers = {2, 4, 6}

                        = 3

Odd numbers = {1, 3, 5}

                       = 3  

Now,

The probability of getting even numbers will be:

= [tex]\frac{Even \ numbers}{Total \ numbers}[/tex]

= [tex]\frac{3}{6}[/tex]

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

hence,

The required probability be:

= P(Even) × P(Even) × P(Even)

= [tex]\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}[/tex]

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

Thus the above answer is correct.

Answer:

See below.

Step-by-step explanation:

1. Look at the marks on the angles of both triangles.

Angles C and F have a single mark (that looks like an arc). They are congruent.

Angles A and D have a double mark (that look like arcs). They are congruent.

Angles B and E have a triple mark (that look like arcs). They are congruent.

Each pair of congruent angles is a pair of corresponding angles.

Corresponding angles:

<C and <F

<A and <D

<B and <E

For corresponding sides, we do this.

First, we write a statement of similarity.

Triangle ABC is similar to triangle DEF.

The statement of similarity must have the corresponding angles in the same order.

The order ABC and the order DEF matches corresponding angles.

The corresponding sides have the vertices of corresponding angles as their endpoints.

Corresponding sides:

AB and DE

BC and EF

AC and DF

2. For similar triangles, the ratios of the lengths of corresponding sides are equal.

The ratios of  the lengths of corresponding sides are equal:

AB/DE = BC/EF = AC/DF

3.

<A is congruent to <D

<B is congruent to <E

<C is congruent to <F

Answer:

[tex]\frac{11}{12}[/tex],[tex]1\frac{1}{4}[/tex],[tex]1\frac{2}{3}[/tex]

Step-by-step explanation:

It wants you to take these 3 fractions and arrange them from least to greatest.

The first thing I did was look for the fraction with no number in front of it.

[tex]\frac{11}{12}[/tex] is the only fraction that has no numbers in front of it. So

The second thing I did was look for the fraction that had the biggest number in front of it. I see that the remaining fractions have the same number in front.

So, I drew 2 circles. 1 of the circles I shaded in and the other I split into 4 equal halves. I shaded in one of the halves. These 2 circles represent [tex]1\frac{1}{4}[/tex].

The next thing I did was draw 2 more circles. I shaded in one of them and slit the other one into 3 equal halves. I shaded in 2 of the halves. These 2 circles represent [tex]1\frac{2}{3}[/tex].

Last, look at the 4 circles and ask yourself which one is the most shaded in. If you said [tex]1\frac{2}{3}[/tex] you are correct. This fraction is the biggest. Meaning that [tex]1\frac{1}{4}[/tex] is in the middle.

Answer:

0.01

Step-by-step explanation:

Water is non viscous liquid and it has less density. The measure volume of water is 10.03 ml at 25 degree Celsius which is used to identify the standard deviation of the water.

Average volume of water 10.03ml.

Standard deviation is 0.0001 + 0.0001

Standard deviation is [tex]\sqrt{0.0002}[/tex]  = 0.01.

Answer: dollars

Step-by-step explanation:

Mean means average and it's calculated by adding the numbers given and then dividing the sum by the amount of numbers that were given.

The standard deviation shows the amount of dispersion or amount of variation of a given set of values. From the question, the only unit of measurement we can see is the dollar sign($).

Answer:

First part 7 units left and 5 units up

The 2nd part is v ≥-7 and the third part is Y≥5

Step-by-step explanation:

Done it in Edge and got it right :)

The transformation of parent function [tex]y = \sqrt{x }[/tex] to [tex]y = \sqrt{x + 7} + 5[/tex] is first translated 7 units left and then it translated 5 units up.

"It is nothing but mean transforming the function from one form to another."

For given question,

We have been given a function [tex]y=\sqrt{x}[/tex]

We need to describe the transformation of the graph for the function [tex]y = \sqrt{x + 7} + 5[/tex]

We know, if f(x) is transformed to f(x + a) then it means function f(x) is translated 'a' units left.

So, [tex]y=\sqrt{x+7}[/tex] means the function [tex]y = \sqrt{x}[/tex] is translated 7 units left.

We know, if f(x) is transformed to f(x ) + a then it means function f(x) is translated 'a' units up.

So, [tex]y = \sqrt{x + 7} + 5[/tex] means the function [tex]y = \sqrt{x + 7}[/tex] is translated 5 units up.

Therefore, the parent function [tex]y = \sqrt{x }[/tex] is first translated 7 units left and then it translated 5 units up.

Answer:If the last number is 1¼ then the answer is ¾

Step-by-step explanation:

From one fraction to the other there is a difference of ¼

¼+¼=½

½+½=¾

¾+¼=1

1+¼=1¼

To identify the difference between the fractions you should get the LCM of the denominator which is 4 then you change all the fractions and make them have the same denominator

½ ,²/4 ,_ ,⁴/4 ,⁵/4

Then work with the numerator

1 , 2, _ ,4 , 5,

The dash is to be filled with 3

So your answer is ¾

Answer:

Let B(a,b) be x1, y1

A(-6,1) be x2,y2

midpoint M(-3,2) be (x,y)

using midpoint formula

(x,y)= [(x1+x2)/2, (y1+y2)/2)

(-3,2) = [(a-6)/2, (b+1)/2}

comparing corresponding value

-3 = (a-6)/2                           (b+1)/2 = 2

-6= a-6                                  b+1=4

a=0                                         b=3

coordinates of B = (0,3)
