Harriet used the work below to determine the percent equivalent to One-eighth.

Step 1: One-eighth = StartFraction question mark Over 100 EndFraction
Step 2: 8 divided by 100 = 0.08
Step 3: 0.08 times 1 = 0.08
Step 4: 0.08 percent

What was Harriet’s error?
In Step 1, she set up the proportions incorrectly.
In Step 2, she divided 8 by 100 instead of 100 by 8, so she cannot multiply the numerator by the factor.
In Step 3, she multiplied the numerator instead of the denominator by the factor.
In Step 4, she forgot to move the decimal.

Step-by-step explanation:

ΔJKL ≅ ΔXYZ

The order of letters in triangle's "names" is important, it indicates the corresponding angles and sides.

∠J ≅ ∠X, ∠K ≅ ∠Y, ∠L ≅ ∠Z

segment JK ≅ segment XY,

segment KL ≅ segment YZ,

segment JL ≅ segment XZ

m∠Z = m∠L = 180° - (60° + 55°) = 65°

(4a + 9)° = 65°

4a = 65 - 9 ⇒ a = 14

XY = JK = 24 units

3b - 6 = 24 ⇒ b = 10

Answer:0.0499

Step-by-step explanation:

Let x be a random variable that represents the salary for a data scientist.

Given: Average salary for a data scientist [tex]\mu=\$83105[/tex]

standard deviation [tex]\sigma=\$10503[/tex]

Sample size : n= 31

The probability that the mean salary of 31 randomly selected data scientists is less than $80,000.

[tex]P(\overline{X}<80000)=P(\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}<\dfrac{80000-83105}{\dfrac{10503}{\sqrt{31}}})\\\\=P(z<-1.646)\ \ \ [z=(\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(z<1.646)\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=1-0.9501= 0.0499[/tex]

Hence, the required probability = 0.0499.

Answer:

donald trump can su*k my d*ck

Step-by-step explanation:

Answer:

1. You account for every dollar you make to where your budget shows you have $0

2. She will have $125 leftover to budget out as she sees fit

3. If she does not account for it she may over spend or think she has extra money

4. I would put it in savings

5. No this is not what it means. This means that your paycheck will be able to cover your expenses.

6. You should put extra money in savings. You never know what will occur and savings can always help.

Step-by-step explanation:

Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.

It is defined as the budgeting method that allows you to fix an amount for everything such as utility expenses, savings, and miscellaneous expenses In other words income minus all expenses plus savings should be equal to zero.

1) The core characteristic of the zero-based budget as follows:

2) Blanca has take-home pay every month = $800

Total expenses = $675

Savings = Income - Total expenses

= $800 - $675 ⇒ $125

We can assume Blanca has savings of $125 at the end of the month.

3) The extra amount = $800 - $675 ⇒ $125

According to a zero-based budget income minus all expenses plus savings should be equal to zero.

Therefore Blanca needs to allocate this amount($125) to some budget category.

4) Blanca has a total of $675 expenses she will have $125 as saving at the end of the month.

She should allocate this amount to savings because it will increase her wealth.

5) Zero-based budget does not mean that at the end of every month Blanca has zero dollars in her bank account because as per the definition zero-based budgeting means income minus expenses should be equal to zero. Blanca has savings and other emergencies funds in her bank account.

Thus, Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.

Answer:

it is A and C

Step-by-step explanation:

If you do the math and equations of all of these, you will find that:

10 is 2.5x bigger than 4 (Side lengths DE and BA)

and if we do the equation:

x · 2.5

(the x variable stands for the different side lengths of triangle ABC)

it will equal the side lengths of the bigger triangle.

and when I finished doing that, I multiplied all of the answers to find the area:

12.5 x 7.5 x 10 which altogether is 937.5

none of the other answers for the total of the triangle add up to be that, but side length EF is 7.5, which I used to get my total answer of 937.5.

So the answer is A and C

Slope = 5

Interpretation = Andre is saving 5 dollars per week

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

Work Shown:

The two points (0,40) and (4,60) are on the line

Use the slope formula

m = (y2-y1)/(x2-x1)

m = (60-40)/(4-0)

m = 20/4

m = 5

The slope is 5.

In this context, it means each time the number of weeks goes up by 1, the amount of his savings goes up by 5. In short, he's saving $5 per week.

note: the y intercept tells us that Andre started off with $40 in his account.

The slope is 5 in  slope-intercept form.

What is in slope-intercept form?

the y intercept tells us that Andre started off with $40 in his account.

Slope = 5

The two points (0,40) and (8,80) are on the line

Use the slope formula

Take any two points

m = (y2-y1)/(x2-x1)

= 80-40/8-0

= 40/8

=5

The slope is 5.

Answer:

65 and 115

Step-by-step explanation:

The two angles are same side interior angles which means they add to 180

3x-5 + 2x-15 = 180

Combine like terms

5x -20 = 180

Add 20 to each side

5x-20+20 = 180+20

5x= 200

Divide by 5

5x/5 = 200/5

x=40

The top angle is

3x-5 = 3*40 -5 = 120-5 = 115

The bottom angle is

2x-15 = 2*40 -15 = 80 -15 = 65
