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

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

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.

The function which has zeros at x = 10 and x = 2 is [tex]\rm f(x)=x^2-12x+20[/tex].
What are the zeros of the function?The zero of a function is any replacement for the variable that will produce an answer of zero.
Graphically, the real zero of a function is where the function's graph crosses the x-axis; that is, the real zero of a function is the x-intercept (s) of the function's graph.
The function which has zeros at x = 10 and x = 2 is;
[tex]\rm f(x)=(x-10)(x-2)\\\\f(x)=x(x-2)-10(x-2)\\\\f(x)= x^2-2x-10x+20\\\\f(x)=x^2-12x+20[/tex]

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

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.
