Please help me with this system of equations problem. No virus links of any kind.
Answer:
The company's expenses and sales will both total $2944 once they have sold 736 oz of links
Step-by-step explanation:
cost: y = 736 + 3x
revenue: y = 4x
y = y, so using substitution
4x = 3x + 736
x = 736
They will therefore need to sell 736 oz of links, and when plugging in 736 as x into both the equations:
y = 736 + 3(736) = 2944
y = 4(736) = 2944

A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month. There were 500 who paid in full each month. For this sample of 500 students, the sample mean credit card balance was reported to be $825. The sample standard deviation of the credit card balances for these 500 students was not reported, but for purposes of this exercise, suppose that it was $195. Is there convincing evidence that college students who pay their credit card balance in full each month have a mean balance that is lower than $907, the value reported for all college students with credit cards?
Required:
a. Carry out a hypothesis test using& significance level of 0.01.
b. State the appropriate null and alternative hypotheses.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
Test statistic:
[tex]t=\frac{(825-905)}{\frac{205}{\sqrt{(500)}}}[/tex]
[tex]=\frac{(-80)}{\frac{205}{22.36}}\\\\=\frac{(-80)}{9.16}\\\\=-8.73[/tex]
Let the p-value=0
We reject H0 because of the p-value <0.01. We have evidence that college kids who pay their credit card bills in full per month have a mean balance of less than $905.

Of the 650 student at westmoreland junior high, 80% will attend the field trip. How many student will attend the field trip?
Answer:
520 students will attend
Step-by-step explanation: sorry forgot to explain. An easy way to do it is to multiply the number your using (650) x the percentage (80%) here's an example: 60% of 1,005 multiply 60 x 1005 = 603
603 is 60% of 1005. ;D
Answer: 520
Step-by-step explanation: A way to find even percentages (10%, 20%, etc) is to take 10% of the original number, in this case, it would be 65, and then multiply it by the first number in the percentage. In this case, it would be;
65 x 8 = 520

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains.
If he has 9 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
9514 1404 393
Answer:
90
Step-by-step explanation:
1 dekameter is 10 meters, so each of Glenn's 9 pieces of ribbon can be cut to make 10 1-meter pieces.
9 × 10 m = 90 m . . . . length of available ribbon
(90 m)/(1 m/piece) = 90 pieces
Glenn can cut 90 1-meter pieces from the ribbon he has.

9514 1404 393
Answer:
-3 leftStep-by-step explanation:
Part 1:
A ÷ E = (-3/2) ÷ (1/2) = -3/1 = -3 . . . value of A÷E
__
Part 2:
Point A is located at -1 1/2 on the number line. The point A÷E is located at -3 on the number line. Larger magnitude negative numbers are to the left, so ...
A÷E is left of A

1,2,3,4,5,6,7
Answer:
3/7
Step-by-step explanation:
1,2,3,4,5,6,7
The word problem is asking the PROBABILITY OF NOT SELECTING A PRIME NUMBER.
PROBABILITY: THE LIKELIHOOD OF AN EVENT.
There are 7 numbers in this data set. Of the seven numbers, four are prime numbers, three of them are not.
Therefore, the probability of not selecting a prime number is 3 in 7, or 3 out of 7 (3/7).

What multiplies to -26 and adds to -25
Answer:
1 and -26
Step-by-step explanation:
Consider the factors of 26 (because the two numbers have to multiply to -26). These are: 1 and 26, 2 and 13.
2 and 13 cannot be added or subtracted from one another to get -25, but 1 and 26 can, or rather 1 and -26.
Plz help me quickly it’s due very soon!!!!
Answer:
Step-by-step explanation:
Both angles together equal 180. Set up your formula as
-4x+5+-13x+39 = 180
Now move your terms to have all x values on one side
-4x-13x = 180-5-39
-17x = 136
x=136 / -17
Use this answer in place of your x in each equation to get the angle.
You got this!

Amy deposits S500 into an account that pays simple interest at a rate of 5% per year. How much Interest will she be paid in the first 4 years?
Answer:
She will be paid $100 in interest in the first 4 years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
Amy deposits $500 into an account that pays simple interest at a rate of 5% per year.
This means that [tex]P = 500, I = 0.05[/tex]
How much Interest will she be paid in the first 4 years?
This is E when [tex]t = 4[/tex]. So
[tex]E = P*I*t = 500*0.05*4 = 100[/tex]
She will be paid $100 in interest in the first 4 years.
Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your dog now?
Answer:
Dog is 2 years old
Step-by-step explanation:
Let dog's age = d
Let friend's age = f
Your dog is 8 years younger than your friend:
d +8 = f
In 2 years, your friend will be three times as old as your dog:
3(d+2) = (f+2)
3d+6 = f+2
3d = f - 4
(sub in f=d+8 from above)
3d = f - 4
3d = d+8 - 4
2d = 4
d = 2
