|x −4| if x >4
Please answer quick will award brainliest!
Answer:
x = −4
Step-by-step explanation:
Add x to both sides of the equation. x + 4 + x = − 4 Add x and x . 2 x + 4 = −4
Subtract 4 from both sides of the equation. 2 x = −4 − 4 Subtract 4 from - 4. 2x = −8
Divide each term in 2x = −8 by 2. 2x/2 = −8/2
Cancel the common factor. 2x/ 2 = −8/2 Divide x by 1. x = −8/2
Divide −8 by 2. x = −4

Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Suppose x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiplying both sides by 100, we get
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Dividing both sides by 50, we get
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
So, the amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.
Suppose that 70% of all faculty members at large public universities in the US use iClickers in their classrooms. We would like to assess if the proportion of faculty members at UM who use iClickers in the classroom is less than the stated rate.

The parameter p calculates the portion of faculty members utilizing the iClikers throughout the classrooms.
An employee's gross pay for a period is $820. The employee takes one withholding for a state allowance of $19. There is also a standard state deduction of $81. The state tax table says that if the amount of wages after subtracting withholding allowances and deductions is over $592 but not over $821, the amount of state income tax to withhold is 6.6% of the excess over $592 plus $16.06. What is the employee's state income tax withholding for the period?
A.$8.45
B.$63.58
C.$24.51
D.$47.52
The employee's state income tax withholding for the period is $24.51, which corresponds to option C.
Step 1: Calculate the wages after subtracting the state allowance and deduction:
Gross pay = $820
State allowance = $19
Standard state deduction = $81
Wages after deductions = Gross pay - State allowance - Standard state deduction
Wages after deductions = $820 - $19 - $81 = $720
Step 2: Check if the wages after deductions are over $592 but not over $821. In this case, the wages are over $592 and under $821.
Step 3: Calculate the excess over $592:
Excess over $592 = Wages after deductions - $592
Excess over $592 = $720 - $592 = $128
Step 4: Calculate the state income tax to withhold:
State income tax = (6.6% of the excess over $592) + $16.06
State income tax = (6.6% of $128) + $16.06
First, calculate 6.6% of $128:
6.6% = 6.6/100 = 0.066
State income tax = 0.066 * $128 = $8.45
Now, add $8.45 to the $16.06:
State income tax = $8.45 + $16.06 = $24.51
So, the employee's state income tax withholding for the period is $24.51, which corresponds to option C.

You put $500 in a savings account. The account earns $20 simple interest in 6 months. What is the annual interest rate? Write your answer as a percent
Answer:
8%
Step-by-step explanation:
For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.
For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.
20 = (500)(r)(0.5)
20 = 250r
r = 0.08 = 8%

A triangle has a perimeter of 40cm. If the three sides of the triangle are n, 3n−5, and 3n−4, what is the length of each side?
9514 1404 393
Answer:
7, 16, 17
Step-by-step explanation:
The sum of the lengths of the three sides is the perimeter:
(n) +(3n -5) +(3n -4) = 40
7n -9 = 40 . . . . . . . . . . . . . . collect terms
7n = 49 . . . . . . . . . . . add 9
n = 7 . . . . . . . . . divide by 7
Then the side lengths are ...
n = 7
3n -5 = 16
3n -4 = 17
Can someone tell me what x and y would be
Step-by-step explanation:
20°+120°+I°=180°
I=40°
using sine rule,
I/sin I=x/sinX
12/sin40=x/sin20
x=12sin20/sin40
x=6.4
using similarly and enlargement,
we have, cw/cp=y/120
8/12=y/120
y=80°
5x + 2y = 15
y = -3x + 4
Answer:
5x+2y=15
y=-3x+4
Substituting the value of y in the first equation..
5x+2(-3x+4)=15
5x-6x+8=15
x = -7
So, y = -3(-7)+4
y = 25
A number is divided by 3 and decreased by 5 is 6. What is the number???
Answer:

answer = 23
Step-by-step explanation:
x-5=6*3
x-5=18
x=18+5
x=23
Answer:
33
Step-by-step explanation:
let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5
[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )
[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )

In a standard deck of cards, what is the probability of drawing a black card followed by drawing a heart?
Answer:
13/102
Step-by-step explanation:
In a standard deck of 52 cards, there are 13 black spades, 13 black clubs, 13 red diamonds and 13 red hearts. There are 26 black cards in the deck of 52 cards.
Probability of drawing a black card = 26/52 = 1/2
Suppose we drew the black card. There are now only 51 cards left in the deck. ALL of the hearts are still there - 13 of them.
Probability of drawing a heart from this deck of 51 = 13/51
In general, for the probability of event A and then event B, we multiply.
1/2 x 13/51 = 13/102
