4 times a number is 12 less than the square of that number. Find the positive solution.
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Given
Let the number be x.
So, we have:
[tex]4 * x[/tex] ----- 4 times a number
[tex]= x^2 - 12[/tex] --- 12 less than its square
The equation becomes
[tex]4x = x^2 - 12[/tex]
Equate to o
[tex]x^2 - 4x - 12 = 0[/tex]
Split
[tex]x^2 - 6x +2x - 12 = 0[/tex]
Factorize
[tex]x(x - 6) +2(x - 6) = 0[/tex]
Factor out x - 6
[tex](x + 2)(x - 6) = 0[/tex]
Split
[tex]x + 2 = 0\ or\ x - 6 = 0[/tex]
Solve for x
[tex]x = -2\ or\ x = 6[/tex]
The positive value is 6

Any number greater than or equal to 18,500 will be rounded to a higher thousand. The maximum integer that will round to 18,000 is 18,499.
There could have been up to 18,499 people at the festival.
The cost of 5 gallons of ice cream has a variance of 49 with a mean of 37 dollars during the summer. What is the probability that the sample mean would be less than 35.2 dollars if a sample of 77 5-gallon pails is randomly selected
Answer:
P ( Z < 35,2 ) = 0,0122 or 1,22 %
Step-by-step explanation:
Assuming a normal distribution:
μ = 37
σ² = 49 σ = 7
Z(s) = ( x - μ ) / σ /√n
Z(s) = ( 35.2 - 37 ) / 7 / √77
Z(s) = - 1.8 * 8.77 / 7
Z(s) = - 2.25
From z- table we find the area under the bell shape curve and it is:
0,0122
Then P ( Z < 35,2 ) = 0,0122 or 1,22 %

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

CALCULATE THE DUSCOUNT AMOUNTcalculate the discount amount answer
[tex]m.p = rs 200 discount percent = 10\%[/tex]
Answer:
The discount amount is 20 rupees.
Step-by-step explanation:
Since there is an initial amount of 200 rupees, to which a discount of 10% is made, to determine the amount of said discount the following calculation must be made:
200 x 10/100 = X
2000/100 = X
20 = X
Therefore, the discount amount is 20 rupees.

A cross-section of an irrigation canal is a parabola. If the surface of the water is 34 ft wide and the canal is deep at the center, how deep is it 9 ft from the edge?
Answer:
6.41 ft
Step-by-step explanation:
Equation is y=ax^2
y=15
x=16.5
15=a(16.5)^2
a=0.055
So, to get depth at 4 ft from edge, I assume my new x value is 12.5.
Derived from 16.5 - 4 = 12.5
So:
y= 0.055 * (12.5)^2
y = 8.59
To get depth, I assume subtract from center depth of 15ft.
15ft - 8.59ft = 6.41ft
Answer is 6.41ft.
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.

What is a system of equation?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, Bridgette plans to attend 4 cardio classes and 5 weightlifting classes, which will last a total of 339 minutes. Next week, she hopes to attend 3 cardio classes and 1 weightlifting class, which will last a total of 158 minutes.
Let number of minutes spend in cardio be c and that of in weightlifting be w,
Establishing the equations, we get,
4c+5w = 339....(i)
3c+w = 158...(ii)
Multiplying eq(ii) by 5 and then subtracting eq(i) from eq(ii)
(15c+5w = 790) - (4c+5w = 339)
11c = 451
c = 41
Put c = 41 in eq(ii)
123+w = 158
w = 35
Hence, Every cardio class lasts for 41 minutes and every weightlifting class lasts for 35 minutes.

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.

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.
