Answer:

y=3

Step-by-step explanation:

12+3y=21

-12       -21    subtract 12 from both sides

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

3y=9  

divide 3 from y and 9, so you can get y by itself

3y/3= y   9/3= 3

so y is equal to 3

Answer:

width:   9 inches

length:  14 inches

Step-by-step explanation:

width:   x

length:  x + 5

perimeter = 2L + 2W

46 = 2(x + 5) + 2x

46 = 2x + 10 + 2x

46 = 4x + 10

36 = 4x

x =  9

width:   9

length:  9 + 5 = 14

Answer:

slope intercept form: y=-5/2x+5

the slope of a parallel line would have m=-5/2

Step-by-step explanation:

to get in slope intercept form, you solve for y and get it alone. first you subtract 5x from both sides to get y alone. then you simplify by dividing by 2.

Parallel lines have the same slope

7/9

Step-by-step explanation:

Answer:

It equals 7/9

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(1/3×3/3)+(4/9×1/1)=?

Complete the multiplication and the equation becomes

3/9+4/9=?

The two fractions now have like denominators so you can add the numerators.

Then:

3+4

------- =7/9

9

This fraction cannot be reduced.

Therefore:

1/3+4/9=7/9

here ur answer 4/9

Answer: σ² = 2.90

Step-by-step explanation: For a frequency table, population variance is calculated by:

[tex]\sigma^{2}=\frac{\Sigma f(x-\mu)^{2}}{\Sigma f}[/tex]

where

f is frequency

μ is expected value or mean of the distribution

In this case, mean of the distribution for a grouped frequency table is calculated by:

[tex]\mu=\Sigma x.f(x)[/tex]

where

x is (as the data is grouped) the mid value of the response time

So, the table is

x          |      f

6.45    |    18

7.45    |    21

8.45    |    34

9.45    |    46

10.45   |    46

11.45    |    25

12.45   |    21

And mean will be:

[tex]\mu=6.45(18)+7.45(21)+8.45(34)+9.45(46)+10.45(46)+11.45(25)+12.45(21)[/tex]

μ = 9.5874

To calculate the variance, the formula above is transformed into

[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]

So, to facilitate the calculations, divide each term in a table:

    f      |      x     |      f.x       |        f.x²    

   18    |    6.45  |    116.1     |   748.845

   21    |   7.45   |  156.45   |  1165.5525

   34   |  8.45    |  287.3     | 2427.685

   46   |  9.45    | 434.7      |  4107.915

   46   | 10.45   | 480.7      |  5023.315

   25   |  11.45   | 286.25    |  3277.5625

   21    | 12.45   | 261.45     | 3255.0525

∑ 211   |             |  2022.95 |  20005.9275

Population variance will be:

[tex]\frac{(\Sigma f.x)^{2}}{\Sigma f} =[/tex] [tex]\frac{(2022.95)^{2}}{211}[/tex] = 19394.9133

[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]

[tex]\sigma^{2}=\frac{20005.9275-19394.9133}{211}[/tex]

σ² = 2.90

The population variance for the response time for EMTs is 2.90.

Answer:

79 degrees i think

Step-by-step explanation:

Lines that are horizontal and straight are always 180 degrees so i just subtracted 180 degrees from 101 and i got 79 degrees

Answer:

x = 79

Step-by-step explanation:

A straghit line is equal to 180 degrees.

If 101 of it is taken, you have to find out what the other side is equal to.

The equation would look like: 101 + x = 180 or 180 - 101 = x

I hope you understand now! :D

Step-by-step explanation:

Answer:

40 minutes

Step-by-step explanation:

It takes 30 mins to shape 10 pots, and heating all 10 pots takes 10 mins. Add 30 and 10 minutes to get: 40 minutes.

Answer:

3p + 10; 40 minutes

Step-by-step explanation:

It takes 3 minutes to shape one pot.

It takes 3p minutes to shape p pots.

A batch of pots has p pots and takes 10 minutes in the kiln.

The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.

The expression is

3p + 10

For a batch of 10 pots, p = 10.

3p + 10 = 3(10) + 10 = 30 + 10 = 40

Answer: 3p + 10; 40 minutes

In the die the total no. of students are 25

We know that,

∴ P(E) = Number of favourable outcome / Number of all possible outcome

Here we have to find the probability of the event of finding the no. of males.

⇛ P(E) = 14 / 25 (Answer)

And we are done !!

Probability helps us to know the chances of an event occurring. The probability that no males are selected is 0.3033.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment.

Now, since we need to compute the probability that no males are selected, which can also be taken as the probability of both the students selected are girls. Therefore, the probability can be written as,

Probability = (14/25) × (13/24)

                  = 182/600

                  = 0.3033

Hence, the probability that no males are selected is 0.3033.
