Answer:

0.1714

Step-by-step explanation:

just substract 9.6 from 66/7 which will give u the other rational number.

then add both the rational numbers to check ur answer.

66/7 + 0.1714 = 9.6

Step-by-step explanation:

an equation is a function, if it delivers for every possible input value x exactly one result value y.

b(x) = y = x² + 3

y - 3 = x²

x = sqrt(y -3)

our formally correct

y = sqrt(x - 3)

that is actually NOT a function, as a square root delivers for most x values 2 y values : a positive and a negative value.

d(x) = -9

that means for every possible value of x the result is -9.

reversing this means that the input value of -9 has infinitely many possible results

that is NOT a function.

m(x) = y = -7x

x = -y/7

or formally correct

y = -x/7

that is a normal function. every possible value of x leads to exactly one value of y.

p(x) = y = 1x¹ = x

y = x is its own inverse function.

and this is, of course, a function. every possible value of x leads to exactly one value of y.

Step-by-step explanation:

[tex]1) \: \: - x + 2y + 2z = - 4 \\ 2z = - 4 + x - 2y \\ z = \frac{ - 4 + x - 2y}{2} \\ \\ 2) \: \: 4x + y - 3z = 13 \\ - 3z = 13 - 4x - y \\ z = \frac{13 - 4x - y}{ - 3} \\ \\ 3) \: \: x - 5y + z = - 23 \\ z = - 23 - x + 5y \\ [/tex]

Answer:

y = - [tex]\frac{1}{3}[/tex]x + 4

Step-by-step explanation:

To find the slope of a perpendicular line, find the negative reciprocal of the slope.

The slope is 3 so the slope of the perpendicular line would be - [tex]\frac{1}{3}[/tex]

________________

Then use point slope form to find the equation of the perpendicular line:

y - [tex]y_{1}[/tex] = m (x -  [tex]x_{1}[/tex] )

point = (6, 2)

slope = - [tex]\frac{1}{3}[/tex]

y - 2 = - [tex]\frac{1}{3}[/tex] (x - 6)

________________

If you want it in slope intercept form, you can just rearrange the equation:

y = 2 - [tex]\frac{1}{3}[/tex]x +2

y = - [tex]\frac{1}{3}[/tex]x + 4

Answer:

B. 0.210

Step-by-step explanation:

Range is the minimum value subtracted from the maximum value. In this case 0.004 is the smallest value and 0.214 is the largest.

Range = 0.214 - 0.004 = 0.210 = B

The range set of the given data is 0.21.

The given data sets are,

0.004

0.007

0.011

0.011

0.012

0.020

0.200

0.214

We know that,

In statistics, the range is the difference between the highest and lowest values for a given data collection.

For instance,

if the given data set is 2,5,8,10,3, the range is 10 - 2 = 8.

As a result, the range can also be defined as the difference between the highest and lowest observations.

The range of observation is the name given to the outcome. In statistics, the range indicates the dispersion of observations.

Now to find the range set pf the given data,

Subtract minimum value to maximum value

Since maximum value = 0.214

And minimum value     = 0.004

Then range set = 0.214 - 0.004

                          =  0.21

Thus, range of set  ⇒ 0.21

Answer:

144 students

Step-by-step explanation:

12/28=3/7

3/7*336=144

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If out of 28 students, 12 students packed their lunch.

The number of students who packed their lunch out of 336 students is 144 students.

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 3 hours.

1 mile in one hour.

We have,

In a class of 28 students, 12 students packed their lunch.

We can write this as:

28 students = 12 students packed lunch ______(1)

We have to make 28 students into 336 students.

This can be done by multiplying 12 on both sides of the equation (1)

Multiply 12 on both sides.

12 x 28 students = 12 x 12 students packed lunch

336 students = 144 students packed lunch

Thus,

The number of students who packed their lunch out of 336 students is 144 students.
