Answer:
c. 3680
Step-by-step explanation:
In 2010, the population was 8000.
In 2014, it increased by 15%.
Population in 2014 :
= 8000 + 15/100×8000
= 8000 + 1200
= 9200.
Now, 2/5 of the population was age 12 or under.
= 2/5 × 9200
= 2×1840
= 3680
Answer - c) 3680

A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?
Answer:
3 doors needed
Step-by-step explanation:
The computation of the no of trucks doors that are needed is shown below:
= serve daily ÷ no of store orders ÷ no of store orders
= 50 ÷ 4 ÷ 4
= 3 doors needed
First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come

Answer: b is the answer
Step-by-step explanation:
solve and graph: 7x-6>22
(pls explain your answer, im confused on this)
Answer:
x>4
Step-by-step explanation:
Solving an inequality is very similar to solving an equation:
Given: 7x-6>22
Add 6 to both sides: 7x>28
Divide both side by 7: x>4
x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

Help please !!! Need help
Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234

It should be random (i think I don't know)
Step-by-step explanation:
Answer:
Yes it is biased
Step-by-step explanation:
Because instead of selecting a random variety of people they chose ones that are using their service...meaning they probably like the service. (I mean why else would they have it then)

How many onto functions are there from a set with three elements to a set with eight elements?
Answer:
0 onto functions
Step-by-step explanation:
Let the sets be [tex]A\ and\ B[/tex] such that:
[tex]n(A) = 3[/tex]
[tex]n(B) = 8[/tex]
Required
The number of onto functions
The condition for onto functions is:
For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A
Since n(B) > n(A) i.e. 8 > 3
Then, there can't be onto functions from A to B
Which set of ordered pairs is a function? {(1,1),(2, 2), (3, 3), (4,4), (5,5)} {(0,0),(1,1),(1, -1),(4,2),(4, -2)} {(2,1),(2,2).(2,3),(2,4),(2,5)} {(1,5).(2.4),(3,3).(2, 2), (1,1)
[tex] \underline{ \underline{ \large{ \red{ \tt{✧ E\: X \: P \: L \: A \: N \: A \: T\: I \:O\: N}}}}} : [/tex]
❀ Here, We are given relation from A to B [ Suppose ] & We have to identify whether they are function or not from the relation A to B.
{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 )}⇢ This is a function from A to B because every element of Set A has unique image in set B.
{( 0,0 ) , ( 1 , 1 ) , ( 1 , -1 ) , ( 4 , 2 ) , ( 4 , -2 ) }⇢ This is not a function because two of the elements of Set A ( 1 & 4 ) are associated to elements -1 , 1 & 2 , -2 respectively of Set B
{ ( 2 , 1 ) , (2 , 2 ) , (2 , 3 ) , (2 , 4 ) , (2 , 5 )⇢ This is not a function because the element of Set A ( 2 ) is associated to all the elements of Set B.
{ ( 1 , 5 ) , ( 2 , 4 ) , ( 3 , 3 ) , (2 , 2 ) , ( 1 , 1 )⇢ This is not a function because the elements of Set A ( 1 & 2 ) are associated to elements ( 5 , 1 & 4 , 2 ) of Set B respectively.
[tex] \boxed{ \boxed{ \large{ \purple{ \tt{A \: N \: S \: W \: E \: R: \{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 ) \} }}}}}[/tex]
♨ Q. What is function ? How can we identify whether the given relation is a function ?
⟶Function is a special type of relation. Function is the refinement of relation. In a relation from A to B , every element of Set A has only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.

Enter the opposite of 4/5 and negitive 7/15
Answer:
-4/5 and 7/15
Step-by-step explanation:
the opposite of a number is a number that is equal length from 0 on a number line. So the opposite of 4/5 is -4/5 and the opposite of -7/15 is 7/15

A Sociology student investigated the association between a country's Literacy Rate and Life Expectancy, and then drew the conclusions listed below. Explain why each statement is incorrect. (Assume that all the calculations were done properly.)
a) The $$R^2$$ of 64% means that the Literacy Rate determines 64% of the Life Expectancy for a country.
b) The slope of the line shows that an increase of 5% in Literacy Rate will produce a 2-year improvement in Life Expectancy.
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). [tex]$R^2$[/tex] does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.

Given:
[tex]sinh(f(x))=1+x^2[/tex]
To find:
The value of f'(x).
Solution:
Formulae used:
[tex]\dfrac{d}{dx}sinh(x)=cosh(x)[/tex]
[tex]\dfrac{d}{dx}x^n=nx^{n-1}[/tex]
[tex]\dfrac{d}{dx}C=0[/tex]
Chain rule:
[tex]\dfrac{d}{dx}[f(g(x))]=f'(g(x))g'(x)[/tex]
Where C is an arbitrary constant.
We have,
[tex]sinh(f(x))=1+x^2[/tex]
Differentiate with respect to x.
[tex]cosh(f(x))f'(x)=0+2x[/tex]
[tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex]
Therefore, the required values is [tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex].
