Please help me if you can. Please also write how you got the answer thank you.

Answers

First state your variables:

a = Andile

Everything is related to Andile and therefore we do not need to make this equation more difficult by adding in more variables.

a + (a - 40) + 2(a - 40) = 380

Expand brackets and simplify:

2a - 40 + 2a - 80 = 380

4a - 120 = 380

4a = 500

Then solve for 'a' by dividing by both sides:

a = $125

Now we know Andile's pay we can find Taylor's quite easily:

t = a - 40

t = 125 - 40

t = $85

Taylor earned $85.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.

1/4x = -10
x = -40

Answers

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

What is a BODMAS rule?

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

$\dfrac{x}{4} + \dfrac{12}{4} = 2$

On simplifying, we have

$\dfrac{x}{4 } + 3 = 2$

Subtract 3 from both sides, we have

$\dfrac{x}{4} = -1$

Multiply the equation by 4, we have

$x = -4$

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.

I need to find an equation, a table, and a graph

Answers

…………..Y=125+ 50x…………

Answer:

earnings = $125 + ($50/vacuum)x

Step-by-step explanation:

This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:

The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.

Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).

Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.

Table:

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

0 $125

1 $125 + $50 = $175

2 $125 + $100 = $225

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

What is the perimeter of the triangle below

Answers

Answer:

P = 36 inches

Step-by-step explanation:

To find the perimeter of the triangle, add up all the sides.

P = s1 + s2+ s3

P = 13+13+10

P = 36 inches

Answer: The perimeter of the triangle is 36 inches. The correct option is d

Step-by-step explanation:

The perimeter of a triangle is calculated by adding the length of all sides of the triangle. This is an isosceles triangle. This means that the length of two sides out of three of the shape have the same length.

In such a triangle, the two equal sides are called the arms. The other side, represented usually as the lowermost, is called the base. The formula to find the perimeter of any isosceles triangle is-

Perimeter=(arm length)*2+base length

Therefore-

Perimeter=(13 inches)*2+10inches=36

Step-by-step explanation:

Answer:

-13.11

Step-by-step explanation:

Remember: Please Excuse My Dear Aunt Sally (PEMDAS)

You use the parentheses first, so it is 18.03-3*(20.76)÷2

So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14

Then, you subtract from left to right, which gives you: -13.11

scientific notation is hard

Answers

the first answer is 8.4x10^5 & the second answer is 9.16x10^-6

Answer:

8.4x10^5 is the first answer. 9.16 x 10^-6 is the second one.

Step-by-step explanation:

Let me explain. To find scientific notation of a number, you have to make the number greater than 1 and less than 10. So for the first number, you would have to move a decimal place 5 times to the right to make 840,000 less than 10 and greater than 1. But, you still have to add the exponent. So the amount of numbers you move the decimal point to the left, that will be your exponent.

2nd. BUT, for the 2nd number, this number is not 1 or greater than 1 or less than 10. So you would have to move it to the right. If your moving a number to the right, remember the exponent will always be negative. So you would move it 6 times to the right.

I hope this made sense. If it didn't, don't worry! You'll get the hang of it.
