Answer: 5
Step-by-step explanation:
If x = 2, the numbers in the brackets should now be 2 and 3.
2+3 = 5.
Because having numbers in brackets like these | | means absolute value, the number you get is always a positive number.

an amusment park sold 9.728$ worth of admission tickets for a seciak roller coaster at night expirement each ticket cost 38$ how many tickets were sold for the special event show your work
Answer:
256
Step-by-step explanation:
The revenue from the sale of n tickets at $38 each is given as ...
38n = 9728 . . . . total sales from special event tickets
Dividing by the coefficient of n gives the number of tickets:
n = 9728/38 = 256

Raymond caught the football 28 out of 35 times at practice. Predict the number of times he will catch the football during the game if it is thrown to him 20 times.
Answer:
16 times
Step-by-step explanation:
This problem is solved by ratio. Since the ratio of 28 out of 25 times is 4:5, he has to catch the ball 4:5 or 4 of 5 times. You multiply both 5 and 4 by 4, because that's how many times he's gonna catch it. 4 x 4 = 16, so the answer is 16 times.
Answer:
(4/5)^20
Step-by-step explanation:
1) First, write the numbers of times Raymond caught the football out of 35 attempts. This is a necessary step in order to obtain an appropriate operand.
28
35
2) Reduce the fraction to lowest terms. This is an optional step but it simplifies the problem.
28 / 4
35 4
= 4
5
3) Raise the fraction to the 20th power. If the ball is thrown at him 20 times, the probability of him successfully catching the ball must be (4/5)^20.
= (4)^2

Often written as x1,2=4±2√2
The solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].
What is completing the square method?Completing the square method is factorizing a quadratic equation, and henceforth finding the roots or zeros of a quadratic polynomial or a quadratic equation.
According to the given question.
We have a quadratic equation
[tex]3x^{2} + 24x - 24 = 0[/tex]
The above quadratic equation can be written as
[tex]3(x^{2} + 8x - 8) = 0[/tex]
[tex]\implies x^{2} + 8x -8= 0[/tex]
Now, we will solve the above equation by completing the square method.
[tex]x^{2} +8x - 8= 0[/tex]
[tex]\implies x^{2} + 2(4x) +(4)^{2} -(4)^{2} -8 = 0[/tex]
[tex]\implies x^{2} + 2(4x) + 16 - 16 -8 = 0[/tex]
[tex]\implies (x+4)^{2} - 24=0[/tex]
[tex]\implies (x+4)^{2} = 24[/tex]
[tex]\implies (x+4)^{2} = 24[/tex]
[tex]\implies (x+4) = \sqrt{24}[/tex]
[tex]\implies x+ 4 = \pm 2\sqrt{6}[/tex]
[tex]\implies x = 2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex]
Hence, the solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.
Find the base and the height of the triangle.
Step-by-step explanation:
h=b-4
A=30ft^2
A=1/2bh
30=1/2b(b-h)
Cross Multiply
60=b(b-4)
60=b^2-4b
b^2-4b-60=0
Factorise the equation
(b^2+6) (-10b-60)
b(b+6)-10(b+6)
(b-10) (b+6)
b-10=0 or b+6=0
b=10 or b=-6
base =10 (since measurement can not be negative)
h=b-4
Sub the value of b
h = 10-4
h=6
So the height is 6ft and base is 10ft

does (-1, 2), (1, 1),( 1 -1), (2,1), (4,2) represent y as a function
No. A function maps one input to exactly one output. The given relation maps 1 to both 1 and -1, as indicated by the pairs (1, 1) and (1, -1).
Two lines are perpendicular. If one line has a slope of 1/2, what is the slope the other line?
The slope of the perpendicular line would be the negative reciprocal of the other line.
negative reciprocal of 1/2 = -2
answer: -2

A researcher wants to compare the mean score on the Achenbach Youth Self Report form for a sample of youth displaced by a
hurricane to the population mean of 50 and a population standard deviation of 10. The researchers report a sample mean of 48 for their
sample of 36 youth. What is the standard error (aka standard error of the mean) for this sample? Round each step to two decimal
places.
Using the Central Limit Theorem, it is found that the standard error for this sample is of 1.67.
What does the Central Limit Theorem state?It states that for a population of standard deviation [tex]\sigma[/tex], the sampling distribution of sample means of size n has standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this problem, we have that [tex]\sigma = 10, n = 36[/tex], hence the standard error is given by:
[tex]s = \frac{10}{\sqrt{36}} = 1.67[/tex]

Jella rode on the bike trail one afternoon. She biked 12 miles in 1 hour and 24 miles in 2 hours
INn FOUR hours Jennifer will travel 12 m/h x4 = 48 miles
it will take Thomas 48 miles / 4 m/hr = 12 hours to reach the bike in the meantime Jennifer has EIGHT hours of walking 3 m/hr x 8 = 24 miles form the bike Thomas now sets out at 10 m/h this is 10 - 3 = 7 m/h faster than Jennifer is walking he will close the 24 miles and catch Jennifer in 7 m/hr *x = 24 m
24/7hours
So Thomas walks for 12 hours then bikes for 24/7 hr = 15 3/7 hrs = ~ 15 hr 26 min
