7. The graph of part of linear function g is shown on the grid. Which inequality best represents the domain of the part shown?​

Answers

Answer:

a

Step-by-step explanation:

Domain means the change in x.

so the domain will be which values of x the fn goes through.

you can see the black line goes from -9 to 2 in x values.

the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.

so x is between -9 and 2, 2 is with equals -9 is without,

so the first one.

The inequality best represents the domain of the part shown should be -9<x ≤2.

What is domain?

Here domain means the change in the x. Here the domain should be the values of with respect to fn. Also, here we have to watch the blank line that goes from  -9 to 2 in x values.

Since 9 should not be filled however 2 should be.

hence, The inequality best represents the domain of the part shown should be -9<x ≤2.

if k-9=5(k-3)find k​

Answers

Answer:

K = 3/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

k−9=5(k−3)

k+−9=(5)(k)+(5)(−3)(Distribute)

k+−9=5k+−15

k−9=5k−15

Step 2: Subtract 5k from both sides.

k−9−5k=5k−15−5k

−4k−9=−15

Step 3: Add 9 to both sides.

−4k−9+9=−15+9

−4k=−6

Step 4: Divide both sides by -4.

-4k/-4 = -6/-4

K = 3/2

Find the midpoint between the pair of points using the Midpoint
Formula. *
(7,-2) and (-4, 2)

Answers

Given parameters:

Coordinates = (7,-2) and (-4, 2)

The formula for the coordinate of the mid point is;

                  [tex]x_{m}, y_{m}[/tex]   =  ( [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2}[/tex] )

where;

[tex]x_{m}, y_{m}[/tex] are the coordinates of the mid points

  x₁  = 7                y₁ = -2

  x₂ = -4               y₂ = 2

   Input the parameters and solve;

     [tex]x_{m}, y_{m} = \frac{7 + (-4)}{2} , \frac{-2 + 2}{2}[/tex]

    [tex]x_{m}, y_{m}[/tex]   = [tex]\frac{3}{2} , 0[/tex]

So the mid point is at [tex]\frac{3}{2} , 0[/tex]

Step-by-step explanation:

Matched pairs t test is used for paired data.  Data sets are "paired" when the two sets have the same number of data points and each data point in a set is related to only one data point in the other set.

A good example is before/after data.  Each set has the same number of data points, and each data point in the after set is related to one in the before set.

B is not an option because, although the samples are the same size, there is not a paired relationship between the sets.

C is not an option because the samples are not the same size.

Answers

Answer:

b/a=c/d Two lines are parallel to each other if they have the same slope. So let's look at the options and see which one matches that statement. b/aâ‹…c/d=â’1 * This is checking to see if the two lines are perpendicular to each other. Almost the exact opposite of parallel. So this is the wrong answer. b/a=c/d * b/a is a legitimate slope. c/d is also a good slope. And they're being checked to see if they're equal to each other. So this is the correct answer. But let's see if the next two options will give us a chuckle or two. b/a=d/c * b/a is OK. d/c almost looks ok, check the figure. And d/c is NOT a slope. The slope is delta Y over delta X. And d/c is delta X over delta Y. The inverse of the slope. So comparing those two values is meaningless. So it's a wrong answer. b/aâ‹…d/c=â’1 * And they're trying the inverse of the slope trick again. WRONG. And they're checking if it's perpendicular. Also wrong. So definitely not a good choice.

Broomhilda manufactures broomsticks for her fellow witch (and wizard) friends. Broomhilda uses a job order cost system and applies overhead to production on the basis of direct labor cost. On September 1, Job 50 (a super deluxe broom complete with a separate sleep space and shower area as well as an espresso machine) was the only job in process. The costs incurred prior to September on this job were as follows: direct materials $20,000, direct labor $12,000, and manufacturing overhead $16,000. As of September 1, Job 49 (a broom shaped like a cat with some extra cargo space for all the cats) had been completed at a cost of $90,000 and was part of finished goods inventory. There was a $15,000 balance in the Raw Materials Inventory account. During the month of September, Broomhilda began production on Jobs 51 and 52, and completed Jobs 50 and 51. Jobs 49 and 50 were also sold on account during the month for $122,000 and $158,000, respectively. The following additional events occurred during the month.1. Purchased additional raw materials of $90,000 on account. 2.
