Step-by-step explanation:

✍️MAD for Juniors:

✔️Write out the individual scores represented in the dot plot:

505, 505, 510, 515, 525, 530, 530, 540, 550, 550

✔️Find the mean of the data set = [tex] \frac{505 + 505 + 510 + 515 + 525 + 530 + 530 + 540 + 550 + 550}{10} = \frac{5,260}{10} = 526 [/tex]

✔️Find |data value - mean|:

|505 - 526| = 21

|505 - 526| = 21

|510 - 526| = 16

|515 - 526| = 11

|525 - 526| = 1

|530 - 526| = 4

|530 - 526| = 4

|540 - 526| = 14

|550 - 526| = 24

|550 - 526| = 24

✔️Find the sum of |data value - mean| and divide by 10:

[tex] \frac{21 + 21 + 16 + 11 + 1 + 4 + 4 + 14 + 24 + 24}{10} = \frac{140}{10} = 14 [/tex]

✅M.A.D = 14

✔️Write out the individual scores represented in the dot plot:

535, 535, 535, 550, 550, 550, 560, 575, 575, 580

✔️Find the mean of the data set = sum of all values in the data set ÷ 10 = 554.5

✔️Find the M.A.D by dividing the sum of |data value - mean| by 10:

[tex] \frac{144}{10} = 14.4 [/tex]

✅M.A.D = 14.4

Answer:

[tex]\Large\boxed{\text{The amount of money changes by \$50 per week.}}[/tex]

[tex]\Large\boxed{s(t) = 70+50t}[/tex]

Step-by-step explanation:

We can create a function based on this scenario.

We know that you start with $70. This would be a constant. So, we already know that our function will contain +70.

If we earn $50 a week, we know that we can create an expression here to find how much we make based on how many weeks we spend, assuming t represents the amount of weeks we spent.

[tex]50t[/tex]

We can add this to our original constant of 70.

[tex]70+50t[/tex]

Since the output will be a function based on how many weeks we spend, we can make it equal to s(t).

[tex]s(t) = 70+50t[/tex]

The slope here is 50, meaning that every week we earn 50 dollars more.

This means the amount of money changes by 50$ per week.

Hope this helped!

Answer:

Step-by-step explanation:

Let the total question on Shelley's math test be x

If 22 questions is equivalent to 88% of the total score, then

88% of x = 22

88/100 x= 22

88x/100 = 22

cross multiply

88x = 22*100

88x = 2200

x = 2200/88

x = 25

Hence 25 questions were on her math test.

Answer:

both people actually did the same work

Step-by-step explanation:

Work = Force × Distance

The person that climbed the steep spiral staircase used more force but covered a shorter distance. On the other hand, the person that walked up a gentle ramp used less force but covered a longer distance. Since both people reached the same height, the force against gravity was the same.  

Based on the information given, the person that will do more work is the young person.

From the information given, it was stated that two people climbed to the roof of a building. The old person walked up a gentle ramp while the young person climbed up a steep spiral staircase.

In this case, since the young person climbed up a steep spiral staircase, the young person will do more work.

Answer:

i. 4∈C => False

ii. 5∈C => True

iii. A = B => False

iv. B=C => True

Step-by-step explanation:

Given sets are:

[tex]A = \{2,3,4\}\\B = \{2,5,6\}\\C = \{5,6,2\}\\D = \{6\}[/tex]

Lets look at the statements one by one.

i. 4∈C

This statement means that 4 is a member of set C. Looking at the members of set C, it can be concluded that the statement is wrong as C doesn't contain 4.

ii. 5∈C

This statement is true as 5 is a member of C.

iii. A=B

This statement states that set A is equal to set B. Two sets are said to be equal if there number of elements and members are same. Set A and Set B have different members so this statement is false.

iv. B=C

Set B and Set C have equal number of members and the members (5,6,2) are also same so the statement is true.

Hence,

i. 4∈C => False

ii. 5∈C => True

iii. A = B => False

iv. B=C => True

Answer:

2x + 5y = -4

Step-by-step explanation:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

========================================================

Explanation:

Let's use point slope form to get

y - y1 = m(x - x1)

y - y1 = -4(x - x1) .... plug in the given slope m = -4

y - 5 = -4(x - 2) .... plug in the given point (x1,y1) = (2,5)

Now we isolate y

y - 5 = -4(x - 2)

y - 5 = -4x + 8

y = -4x + 8 + 5

y = -4x + 13

This equation is in slope intercept form y = mx+b

m = -4 is the slope

b = 13 is the y intercept

To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side

y = -4x+13

y+4x = 13

4x + y = 13 is the final answer

This is in standard form Ax+By = C where

A = 4

B = 1

C = 13

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

Let's check the answer. Plug in (x,y) = (2,5) to find that...

4x+y = 13

4*2 + 5 = 13

8 + 5 = 13

13 = 13

We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.
