Answer:
Step-by-step explanation:
Like terms have same variable with same power. Combine the like terms. Add / subtract the coeffiecient of the like terms.
9x² and 9x² are like terms
-8 and 3 are like terms.
9x² - 8 + 9x² + 9x + 3 = 9x² + 9x² +9x - 8 + 3
= 18x² + 9x - 5

According to the College Board, the probability that a student forgets to bring their ID with them when they take their SAT is 3%. A random sample of
500 students was selected. Let p-hat be the proportion of the sample which forgot their ID.
1. What is the mean of the sampling proportion?
2. What is the standard deviation of the sampling proportion?
(Round to the nearest thousandth. )
The mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have:
p = 0.03
n = 500 students
[tex]\rm {\hat p} - Normal[/tex]
So the mean:
[tex]\rm \mu _\hat p \ = \ p \ = \ 0.03[/tex]
For standard deviation:
[tex]\rm \sigma_p = \sqrt{\frac{pq}{m} }[/tex]
q = 1 - p = 1 - 0.03 = 0.97
[tex]\rm \sigma_p = \sqrt{\frac{0.03\times 0.97}{500} }[/tex]
[tex]\rm \sigma_p = 0.008[/tex]
Thus, the mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

Can anyone help please? i need this now look at the picture below and write down Explaining how rays AB and AC form both a line and an angle.
Answer:
The points A,B, and C are collinear, so both segments AB and AC form one straight line.
Since segments AB and AC have a common point A so they form an angle BAC

NU = 13
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
As we can see in the given figure, The two triangles are congruent to each other by many criterias, so we can infer that Their corresponding sides are of equal length.
That is :
[tex]\qquad \tt \dashrightarrow \:2x + 5 = 13[/tex]
[tex]\qquad \tt \dashrightarrow \:2x = 13 - 5[/tex]
[tex]\qquad \tt \dashrightarrow \:2x = 8[/tex]
[tex]\qquad \tt \dashrightarrow \:x = 8 \div 2[/tex]
[tex]\qquad \tt \dashrightarrow \:x = 4[/tex]
Therefore, value of x is 4
Answer:
x = 4
Step-by-step explanation:
the point here is congruent triangles.
according to the image,
2x + 5 = 13 <---- subtract constants
2x = 13 - 5 = 8 <--- finalize
2x = 8 <----------- divide both sides by 2
2x / 2 = 8 / 2 <-- finalize
x = 4 <--- answer
8. The Computer Shop sells computers. The shop has a fixed the shop has a fixed cost of $1500 per
week. Its average cost per computer is $649 each, and the average selling price is
$899 each.
a. Write the linear cost function
b. Write the linear revenue function
I
c. Find the cost of selling 37 computers per week
d. Find the revenue from selling 37 computers
e. Find the break-even point.
The linear cost function of the computer shop in this scenario will be C(x) = 649x + 1500.
How to calculate the functions?From the information, the linear cost function is C(x) = 649x + 1500 and the linear revenue function will be R(x) = 899x.
The cost of selling 37 computers will be:
C(x) = 649x + 1500
C(x) = 649(37) + 1500
C = 25513
The revenue from selling 37 computers will be:
R(x) = 899x.
R = 899(37)
R = 33263
The breakeven point will be:
649x + 1500 = 899x
899x - 649x = 1500.
250x = 1500
x = 1500/250
x = 6

Answer:
150-179 minutes
Step-by-step explanation:
The most common interval (the tallest graph) of minutes students spent watching watching TV?
The correct answer should be 150-179 minutes because it's the most common, meaning that a lot of students spent 150-179 minutes watching TV.
Hope this helps!
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
As per the given graph we can observe the number of students which watched TV for certain intervals.
According to question, we have to find the common interval of minutes students spent watching TV~
That means : we have to find the time interval in which most of the students prefer to watch TV ~
Hence, the most common interval is :

8(p-6) > 4(p-4)
How do I solve?
Answer:
p > 8
Step-by-step explanation:
8p - 48 > 4p - 16
plus 48 on both sides
8p > 4p + 32
minus 4p on both sides
4p > 32
divide 4 on both sides, 32 ÷ 4 = 8, so,
p>8
Answer:
P > 8 ??? I don't know if this is right and if its not then sorry lol
Step-by-step explanation:
Multiply 8(p-6) and 4(p-4)
You will get 8p - 48 > 4p - 16
Then add 48 to -16
Then you will get 8p > 4p + 32
Then subtract 4p from 8p
Then you will get 4p > 32
Then divide 4 from 4p and 32
Then you will get p > 8

$172.80
* i will award brainlist
Answer:
$172.80
Step-by-step explanation:
The phone cost $800
Decreases by 2/5 every year. So the cost would be 3/5 (instead of doing 800 - 800 *2/5 its easier to just do 800*3/5)
Here is a equation for this question:
[tex]800* (\frac{3}{5})^{t}[/tex]

153 apples, 255 oranges, 357 pears are to be distributed to a group of children. Suppose each child in the group receives an equal number for each type of fruit.
a) Find the least possible number of children in the group
b) the maximum possible number of children in the group
c) the least possible number of apples, oranges and pears each child can receive
d) the maximum possible number of apples, oranges and pears each child can receive.
Answer:
Below in bold.
Step-by-step explanation:
a) we need the grestest common factor of theses values
153 = 3 * 3 * 17
255 = 3 * 5*17
357 = 3 * 7 * 17
The GCF = 3 * 17 = 51.
a) the least possible number of children is 3.
b) The maximum number is 51 ( as 51 is the GCF of the given values).
c) the least possible number of fruits is when b) occurs, that is:
153/51, 255/51 and 357/51
= 3 apples , 5 oranges and 7 pears.
d) the maximum number of fruits is :
153/3, 255/3 and 357/3
= 51 apples , 85 oranges and 119 pears.
Answer:
a) 3 children
b) 51 children
c) 3 apples, 5 oranges and 7 pears
d) 51 apples, 85 oranges and 119 pears
Step-by-step explanation:
lnc - Least possible number of children in group
mnc - maximum possible number of children in group
a - Apples
o - Oranges
p - Pears
a = 153
o = 255
p = 357
a)
To solve this, find the highest divisor for the apples, oranges and pears.
[tex]a = \frac{153}{51} [/tex]
[tex]a = 3[/tex]
[tex]o = \frac{255}{85} [/tex]
[tex]o = 3[/tex]
[tex]p = \frac{357}{119} [/tex]
[tex]p = 3[/tex]
In order for each child to get 51 apples, 85 oranges and 119 pears, there would need to be a minimum of 3 children in the group.
[tex]lnc \: = 3[/tex]
b)
To solve this, find the lowest divisor for the apples, oranges and pears.
[tex]a = \frac{153}{3} [/tex]
[tex]a = 51[/tex]
[tex]o = \frac{255}{5} [/tex]
[tex]o = 51[/tex]
[tex]p = \frac{357}{7} [/tex]
[tex]p = 51[/tex]
In order for each child to get 3 apples, 5 oranges and 7 pears, there would need to be a maximum of 51 children in the group.
[tex]mnc = 51[/tex]
c)
In a group of 51, each child will get:
- 3 apples
- 5 oranges
- 7 pears
d)
In a group of 3, each child will get
- 51 apples
- 85 oranges
- 119 pears

The length of one leg of a right triangle is 9 ft. The length of the hypotenuse is 3 feet longer than the other leg. Find the length of the hypotenuse and the other leg.
The length of the hypotenuse is ___ ft.

We'll solve this using the Pythagorean theorem, we know that,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}}[/tex]
So, As it is given in the question that, the length of one leg of a right triangle is 9 ft and the length of the hypotenuse is 3 feet longer than the other leg and we are to find the length of the hypotenuse and the other leg.
[tex] \: [/tex]
Let us assume the other leg as x ft and therefore the hypotenuse will be (x + 3) ft.
