Answer:
Mean - 79
Median- 81
Range- 11
Step-by-step explanation:
Mean aka average = add all the numbers together and divide it by the number of numbers there were to find the mean of something.
in this case : 81 + 82 + 84+ 75+73+75 + 83 = 553 divided by 7 = 79
Median - Rearrange the set of numbers from least to greatest or greatest to least and find the middle number to find the median
In this case : 73, 75, 75, 81, 82, 83, 84 = The median is 81
Range - Substract the highest and the lowest number from the set of numbers to find the range.
In this case : 84 - 73 = 11

Answer:
y = 1/3*2^xStep-by-step explanation:
Given function
y = c*a^xThe points (-1, 1/6) and (1, 2/3) lie on the graph
Substitute the values of x and y to get the system of equations:
1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c2/3 = c*a^1 ⇒ 2/3 = acSubstitute a and solve for c:
2/3 = 6c*c1/9 = c²c = √1/9c = 1/3Find a:
a = 6c = 6*1/3 = 2The equation of the function:

Answer:
Answer vary:
The better buy is 5 cans of green beans at the Village Market.
Step-by-step explanation:
honestly in my opinion that‘s my answer.
if 10 cans cost $5.10 and 5 cans cost $2.30, think about if you add another $2.30 for another 5 cans the cost is $4.60 and you get 10 cans. and that’s obviously cheaper than the other buy.
10 cans = $5.10
5 cans = $2.30.
(the 5 can offer)
2.30+2.30= $4.60

Simplify the rational Expression
Answers
Answer:
[tex]\frac{x^2+2x}{x-3}[/tex]
Step-by-step explanation:
We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.
Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)
Denominator (factoring by grouping):
x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)
Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:
x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

Answer:
(c)512 because64 times 1.5 equal 512.
Step-by-step explanation:
(c) 512
(b) 8 to the third power
(E) √64 to the third power
all of these equal 512
The equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³.
What is exponent and power?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
The number of times a number is multiplied by itself is defined by the exponent. A mathematical term called the power illustrates the repeated multiplication of the same integer or factor.
Given:
[tex]64^{3/2[/tex]
Now, we know that 64 is square of 8.
so, [tex]64^{3/2[/tex]= [tex](8^2)^{3/2[/tex]
= 8³
= 512
So, the equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³

Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27

A farmer packs eggs into cartons of 12. The farmer has 109
eggs. She wants to keep 13 of those eggs for her family.
How many cartons will the farmer be able to sell?
Answers
Answer:
109 divided by 12 is about 9.3 carton thingys so she would most likley sell 8
so she can keep some
Step-by-step explanation:
The farmer sells 6 cartoons.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Eggs= 109
A carton contain= 12 eggs
If the farmer takes away 13 eggs, the eggs left
= 109 - 13
= 96 eggs.
So, the number of cartoons will famer sell
= 96 / 12
= 6 cartoons.
Hence, the farmer sells 6 cartoons.
