Answer:
30-3=27
Step-by-step explanation:
Finding the deviation of this is pretty simple
1) Find the mean
By finding the mean, you add the numbers together, and divide the sum by the number of numbers, in this case there are 10 numbers, so divide by 10
2) Subtract the data value, basically adding all of the numbers up, and subtracting it by 3, the mean.
the number sets:
3,1,5,5,2,3,2,3,4,2
mean=
30/10
by finding this, i added the numbers and divided it by the amount of numbers.
This would equal to 3.
Now, all you have to do is subtract 3 from the data value
The data value is 30, subtracted by 3 would be 27
Sorry if I am wrong, I am just 4th grade :(
I am sure I am right, but in case it IS wrong, use the formula in the explanation :)
I might've gotten it wrong because the numbers were unclear, but I think it is correct:)
Answer: 1
Step-by-step explanation:
3+1+5+5+2+3+2+3+4+2= 30
30/10 =3
3 - 3 =0
3 - 1 = 2
3 - 5 =2
3 - 5 =2
3 - 2 = 1
3 - 3 =0
3 - 2 = 1
3 - 3 = 0
3 - 4 = 1
3 - 2 = 1
0+2+2+2+1+0+1+0+1+1
10/10 is 1
Each table in a library can seat up to 5 people. There are enough tables for 75 people. How many tables are there in the library?
Answer:
15 tables
Step-by-step explanation:
75/5 = 15
Answer:
There are 15 tables in the library.
Step-by-step explanation:
You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

Use distribute property to simplify the expression 5(x+4)
Answer:
[tex]\huge\fbox{5x+20}[/tex]
Step-by-step explanation:
Hi there!
The Distributive Property states that
[tex]\bold{a(b+c)=ab+ac}[/tex]
So, we multiplied a by everything inside the parentheses.
Now, let's use this property to solve our problem:
[tex]\bold{5(x+4)}\\\bold{5x+20}[/tex]

Answer:
[tex]684\:\mathrm{cm^2}[/tex]
Step-by-step explanation:
The area of any triangle is equal to [tex]A=\frac{1}{2}\cdot a\cdot b\cdot \sin C[/tex], where [tex]a[/tex] and [tex]b[/tex] are two sides of a triangle and [tex]C[/tex] is the angle between them.
Plugging in given values, we have:
[tex]A=\frac{1}{2}\cdot 27\cdot 82\cdot \sin 162^{\circ}=\boxed{684\:\mathrm{cm^2}}[/tex]

A data set is made up of these values.
1, 2, 4, 5, 8, 10, 11
Find the interquartile range.
A. 2 - 1 = 1
B. 11 - 1 = 10
C. 10 - 2 = 8
D. 11 - 5 = 6
Answer:
C. 10 - 2 = 8
Step-by-step explanation:
[tex] = (Q _{3} - Q _{1}) \\ = ( \frac{3}{4} \times 7) - ( \frac{1}{4} \times 7) \\ = (6 {}^{th} - {2}^{nd} ) \\ = (10 - 2) \\ = 6[/tex]

Complete Question
Carmen is putting together a business plan for her sandwich restaurant, Subs Away, so she can expand to another location. She wants to include some information about recent sales but only has certain information about last month's sales. She currently offers ham, turkey and vegetarian sandwiches. She sells the ham sandwiches for $10 each and the turkey sandwiches for $11.25.
Last Month's Vegetarian Sales
Total Sandwiches Sold 75
Total Income $712.50
How much does Carmen charge for the vegetarian sandwich?
Answer:
[tex]X=9.5[/tex]
Step-by-step explanation:
From the question we are told that:
Total Vegetarian Sandwiches Sold [tex]T_{vs}=75[/tex]
Total Vegetarian Sandwiches Income [tex]T_{vi}=$712.50[/tex]
Generally the equation for Cost of vegetarian sandwich is mathematically given by
[tex]X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}[/tex]
[tex]X=\frac{T_{vi}}{T_{vs}}[/tex]
[tex]X=\frac{712.50}{75}[/tex]
[tex]X=\$9.5[/tex]

Answer:
I cannot give you a full answer because it's missing crucial information- the points on the graph. However, I can give you insight!
Suppose one point is (2,3), if you want to scale it by a factor of 3, you would simply multiply both variables by 3. So the new point would be (6,9).
If you want to scale (4,7) by factor of 2, you would multiply the 4 and the 7 with 2. The new point would be (8,14).
What is the area of the figure?
Answer:
20m
Step-by-step explanation:
the 4m and 2m on the right can make a rectangle for 8m, then you can make another rectangle on the left side with the remaining 4m (from the 8m side) to make 8m so now were at 16, the triangle remainse, the length is 4m and the height is 2m making 8/2 or 4
16+4 = 20m

They need to make 70 baggies of cookies that each have 4 cookies in them. The recipe they are using says that one batch will make 2 dozen cookies.
Answer:
They need to make at least 12 batches.
Step-by-step explanation:
First, we need to find how many cookies in total, so we multiply 70 by 4.
70*4 = 280.
Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.
Time to check:
12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.
Hope this helps.

What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 = -8 - 16 Step Two: -6 • -6t = -24 • -6 Solution: t = 144
Answer:
t = 4
Step-by-step explanation:
In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.
-6t = -24
÷-6 ÷-6
t = 4
When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?
Answer:
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
Step-by-step explanation:
Given
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
[tex]h(x) = -2(2x^2 - 8)[/tex]
[tex]h(x) = -4(x^2 - 4)[/tex]
[tex]h(x) = -4x^2 + 16[/tex]
Required
Which shows the zeros of h(x)
To determine the zeros of a function, the function must be written as:
[tex]h(x) = n(x \± a)(x \± b)[/tex]
Where
[tex]n \ne 0[/tex]
[tex]\± a,\± b[/tex] are the zeros
Of options (a) to (d), only (a) is written in the form:
[tex]h(x) = n(x \± a)(x \± b)[/tex]
i.e.
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
Other options do not show the zeros
