Answer:

3/12 = 4/12

or

3/12 = 1/3

being are last boxes to autofill.

Step-by-step explanation:

1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3

When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.

12 / 4 = 3

we get 3/12

Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12

The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.

As 4/12 = 1/3

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

a) We need a sample size of at least 2401.

b) We need a sample size of at least 1936.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

In which

z is the zscore that has a pvalue of .

The margin of error is:

95% confidence level

So , z is the value of Z that has a pvalue of , so .

(a) you are unwilling to predict the proportion value at your school and​

We use , which is when we are going to need the largest sample size.

So we need to find We need a sample size of at least 2401.

(b) you use the results from the surveyed school as a guideline.

Now the same calculation, just with . So

We need a sample size of at least 1936.

Answer:

The true mean volume of p

aint in each can is greater than or equals to 400ml

Step-by-step explanation:

The symbol of μ represents the mean of a data.

Mean can be defined as the average value of a set of data

Let consider the question.

We know that

μ ≥ 400ml

Where the sign ≥ means "greater than or equals to"

Which means that μ is greater than or equals to 400ml

So the solution is:

1st blank = greater than

2nd blank = equals to

Answer:

A

Step-by-step explanation:

The options b and d are suitable equations. The equations are \(\frac{1}{2} m+4=20 and 4=20-\frac{1}{2}m\). The number of students in Bryan's homeroom in this equation is m.

The following information is given in the question: The number of students who possess tickets = 20. And, m is the number of students in Bryan's homeroom. let us solve the sum using this particular equation \(\frac{1}{2} m+4=20\) to figure out how many students are in Bryan's homeroom.

On solving the given equation,

\(\frac{1}{2} m+4=20 \\4+\frac{2}{m} = 20\\8+m=40\\m= 40-8 = 32. \\\)

As a result, there are 32 students in Bryan's homeroom(m). The options that are used to find the number of students, m, in Bryan’s homeroom are  \(\frac{1}{2} m+4=20\) and \(4=20-\frac{1}{2}m\). All other options do not satisfy the conditions given in the question.

Step-by-step explanation:

255 - 99 = ?

255 can become 250

99 can become 100

250 - 100 = 150

To check, 255-99 = 156 so our answer seems to be correct and a close estimate! ✔

Answer: 200/7

Step-by-step explanation:

This creates 3 similar right triangle

you would put similar parts  on top and the similar parts on bottom of proportions.

ex.

\(\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}\)

in your problem they gave the short legs and long legs of right triangel

The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.

\(\frac{long leg}{short leg} =\frac{long leg}{short leg}\)

\(\frac{x}{20} = \frac{20}{14}\)

x=(400)/14 = 200/7

You could also make your proportion where

parts of 1 triangle = equivalent parts of the other

ex.

\(\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}\)

The mathematical expression can be written as 6t, 2.6t, and 4.2t.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the sum of 6.2 times the number t, 2.6 times the number t, and 4.2 times the number t.

The expression will be written as:-

6t, 2.6t, and 4.2t.

Hence, It is possible to write a mathematical expression as 6t, 2.6t, and 4.2t.

Answer:

Answer:

29)  m∠A = 83°

       m∠B = 7°

32)  m∠A = 103°

       m∠B = 77°

33)  m∠A = 24°

       m∠B = 156°

Step-by-step explanation:

Complementary angles:  Two angles whose measures sum to 90°.

\(\implies m \angle A + m \angle B=90^{\circ}\)

\(\implies (16x - 13)^{\circ} + (2x - 5)^{\circ}=90^{\circ}\)

\(\implies 16x - 13 + 2x - 5=90\)

\(\implies 18x -18=90\)

\(\implies 18x =108\)

\(\implies x=6\)

Substitute the found value of x into the expression for angle A:

\(\implies m \angle A = \left(16 \cdot 6 - 13 \right)^{\circ}\)

\(\implies m \angle A = \left(96 - 13 \right)^{\circ}\)

\(\implies m \angle A = 83^{\circ}\)

As the sum of angles A and B is 90°:

\(\implies m \angle B = 90^{\circ}-m \angle A\)

\(\implies m \angle B = 90^{\circ}-83^{\circ}\)

\(\implies m \angle B = 7^{\circ}\)

-------------------------------------------------------------------------------------------------

Supplementary angles:  Two angles whose measures sum to 180°.

\(\implies m \angle A + m \angle B=180^{\circ}\)

\(\implies (x+11)^{\circ} + (x-15)^{\circ}=180^{\circ}\)

\(\implies x+11+ x-15=180\)

\(\implies 2x-4=180\)

\(\implies 2x=184\)

\(\implies x=92\)

Substitute the found value of x into the expression for angle A:

\(\implies m \angle A = \left(92+11 \right)^{\circ}\)

\(\implies m \angle A =103^{\circ}\)

As the sum of angles A and B is 180°:

\(\implies m \angle B = 180^{\circ}-m \angle A\)

\(\implies m \angle B = 180^{\circ}-103^{\circ}\)

\(\implies m \angle B = 77^{\circ}\)

-------------------------------------------------------------------------------------------------

Supplementary angles:  Two angles whose measures sum to 180°.

\(\implies m \angle A + m \angle B=180^{\circ}\)

\(\implies (9x-12)^{\circ} + (24x+60)^{\circ}=180^{\circ}\)

\(\implies 9x-12+24x+60=180\)

\(\implies 33x+48=180\)

\(\implies 33x=132\)

\(\implies x=4\)

Substitute the found value of x into the expression for angle A:

\(\implies m \angle A = \left(9 \cdot 4-12 \right)^{\circ}\)

\(\implies m \angle A = \left(36-12 \right)^{\circ}\)

\(\implies m \angle A =24^{\circ}\)

As the sum of angles A and B is 180°:

\(\implies m \angle B = 180^{\circ}-m \angle A\)

\(\implies m \angle B = 180^{\circ}-24^{\circ}\)

\(\implies m \angle B = 156^{\circ}\)
