Write an equation of the line shown. Then use the equation to find the value of x when y = 26

stich3 [128]

Answer:

y = 4x - 2

When y = 26, x = 7.

Step-by-step explanation:

Use the two points on the line to calculate the slope of the line, then use this slope and the y-intercept to write an equation for the line.

Slope formula:

(y2 - y1)/(x2 - x1)

We have these two points on the graph: (1, 2), (-1, -6).

Substitute these points into the slope formula and find the slope of the line.

(-6-2)/(-1-1)
(-8)/(-2)
4

The slope of the line is 4. Now, use the point-slope formula to write an equation for the line.

Point-slope formula:

y - y1 = m(x - x1)
y - 2 = 4(x - 1)
y -2 = 4x - 4
y = 4x - 2

To find the value of x when y = 26, substitute y = 26 into the equation and solve for x.

26 = 4x - 2
28 = 4x
x = 7

What is the fraction of 1.38

deff fn [24]

Solve:-

1.38 = 1.38/1
1.38 × 100 = 138
1 × 100 = 100
138/100
69/50
1 19/50

1.38 = 138/50 = 69/50 = 1 19/50

Exhibit 18-2 Students in statistics classes were asked whether they preferred a 10-minute break or to get out of class 10 minute

tankabanditka [31]

Answer:

The mean and the standard deviation of the sampling distribution of the number of students who preferred to get out early are 0.533 and 0.82

Step-by-step explanation:

According to the given data we have the following:

Total sample of students= 150

80 students preferred to get out 10 minutes early

Therefore, the mean of the sampling distribution of the number of students who preferred to get out early is = 80/150 = 0.533

Therefore, standard deviation of the sampling distribution of the number of students who preferred to get out early= phat - p0/sqrt(p0(1-p)/)

= 0.533-0.5/sqrt(0.5*0.5/15))

= 0.816 = 0.82

Cuidadosamente, Severina, a empregada dos “Silva” arruma uma bela cesta de maçãs. O patriarca ao ver as maçãs toma para si 1/6 d

sveticcg [70]

There was a total of 18 apples

<u>Step-by-step explanation:</u>

Let us consider the total no. of apples be 'a'.

Patriarca took 1/6 of the apples. So the remaining apples is,

a - (1/6) a= (5/6) a

Step 1:

His wife takes (1/5) of the rest of the apples. So after she takes the apples the remaining apples will be,

(5/6) a - (1/5) (5/6) a

(5/6) a - (1/6) a = (4/6) a

Step 2 :

Her elder son takes (1/4) of the remaining apples. So,

(4/6) a - (1/4) (4/6) a

(4/6) a - (1/6) a = (3/6) a

Step 3:

Middle son takes (1/3) of the remaining apples. So,

(3/6) a - (1/3) (3/6) a

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

Step 4:

Younger son takes (1/2) of the remaining apples. So,

(2/6) a - (1/2) (2/6) a

(2/6) a - (1/6) a = (1/6) a

After work she takes the remaining 3 apples. So the remaining apples were 3

So,

(1/6) a = 3

a = 3 x 6

a = 18 apples

There were a total of 18 apples.
