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

Answer:
y = -2x² + 12x - 14
Step-by-step explanation:
Isolate the "-2" in (x - 3)² by using brackets:
⇒ y = -2(x - 3)² + 4⇒ y = -2[(x - 3)²] + 4Using the formula (a - b)² = a² - 2ab + b²:
⇒ y = -2[(x - 3)²] + 4⇒ y = -2[x² - 2(x)(3) + 3²] + 4Open the brackets on the R.H.S
⇒ y = -2[x² - 6(x) + 9] + 4⇒ y = -2x² + 12(x) - 18 + 4Simplify the expression on the R.H.S
⇒ y = -2x² + 12(x) - 18 + 4⇒ y = -2x² + 12x - 14Which of the following correlation coefficients represents the weakest correlation?

The correlation coefficient that represents the weakest correlation amongst the given options is -0.1.
What is correlation?Correlation is a statistical measure used to measure the relationship that exists between two variables. A value of one represents a perfect correlation. A value of zero signfies that the variables have no relationship.
So, the correlation coeffieicent with a value closest to zero would have the weakest correlation.

According to information from a college admissions office, 62% of the students there attended public high schools, 26% attended private high schools, 2% were home schooled, and the remaining students attended schools in other countries. Among this college's Honors Graduates last year there were 47 who came from public schools, 29 from private schools, 4 who had been home schooled, and 4 students from abroad. Is there any evidence that one type of high school might better equip students to attain high academic honors at this college
The p-value shows that onea type of high school might not be better equip students to attain high academic honors at this college.
What is a p-value?A p-value simply means a statistical measurement that is used to validate a hypothesis against the observed data.
Here, from the table, the p-value is 0.0393. Since the p-value is less than the level of significance which is 0.05, we are going to reject the null hypothesis.

What is the range of the function f(x) = 3x2 6x – 8?
The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).
What are domain and range?The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.

$798.80
$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:

the diameter of fishing line varies. Fishing lines can have a diameter as small as 2 x 102 and as large
Answer:
We know that:
small diameter = 2 * 10^-2 in
large diameter = 6 * 10^-2 in
We want to know how many times larger is the thin diameter compared to the large one.
We will do this as follows:
large diameter = k * small diameter
where k is the number of times that we want to find
6 * 10^-2 = k * 2 * 10^-2
k = (6 * 10^-2) / (2 * 10^-2)
k = 3
This means that the large diameter is 3 times the small one.

Alice is making a necklace. She has a chain that is 400 mm long. She puts forty 1.7 mm beads, twenty-seven 6.5 mm beads, and eight 3.4 mm beads on the chain. How much of the 400 mm chain is left without bead?
Answer:
129.3mm chain left without beads
Step-by-step explanation:
Equation:
400mm long chain - [(40 x 1.7mm) + (27 x 6.5mm) + (8 x 3.4mm)]
= chain left without beads
Calculation:
40 beads x 1.7mm = 68mm
27 beads x 6.5mm = 175.5mm
8 beads x 3.4mm = 27.2mm
(68mm + 175.5 mm + 27.2mm) = 270.7mm chain with beads
400mm chain - 270.7mm chain with beads
= 129.3mm chain left without beads
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

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

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.

Now, substituting the values in the formula :
