The mean of four numbers is 7. Three of the numbers are 5, 7, and 7. What is the fourth number? Explain your reasoning.
Answer:
9
Step-by-step explanation:
The mean is equal to the sum of all numbers divided by the amount of numbers there are. If we represent the mean as m, sum as s, and number of numbers as n, we can write our equation as
m = s/n
Therefore, as we know the mean (7) and number of numbers (4), we can plug those in to find the sum.
7 = s / 4
Multiply both sides by 4
28 = s
We then have our sum. Because we know 3 numbers, and there are 4 total, there is one number left to figure out. Our current sum is 5+7+7 = 19, and we need a sum of 28. The difference between the sums, equivalent to the fourth number, is 28-19=9.

What is the first step in solving quadratic equations by finding square roots? a. give the positive and negative answer c. square root both sides to isolate x b. isolate the x squared by using inverse operations d. none of these Please select the best answer from the choices provided A B C D
Answer:
C: isolate the x squared by using inverse operations
Step-by-step explanation:
This method of solving quadratic equation is used when there is only x² term and no x term. Thus;
For example, we have a quadratic equation;
x² - 1 = 80
To solve this by square root method, the first step we have to take is to isolate the x² term by inverse operation which is by addition of 1 to both sides to get rid of the -1 on the left side so that x² can be isolated.

Answer:
The amount of wood left is 36 9/16 in
Step-by-step explanation:
Here, we want to get the amount of wood left
To calculate this, we have to subtract what is cut and what is wasted from the original total length
So we have what is left as follows;
45 1/2 - 8 7/8 - 1/16
45 1/2 = 91/2
8 7/8 = 71/8
91/2 - 71/8 - 1/16
(728 - 142 - 1)/16
585/16 = 36 9/16 in

(20 points) thanks so much!!
Step-by-step explanation:
Let us say x=2 and y=1
Using the formula,
=>((2^2)-(1^2))^2+(2(2)(1))^2=((2^2)+(1^2))^2
=>(4-1)^2+(4)^2=(4+1)^2
=>(3)^2+(4)^2=(5)^2

PLEASE HELPPPPPP Meeeeeee hurrry
Answer: Choice C
1, 3, 6, 8, 10, 12, 13, 13, 16, 18, 19
===========================================================
Explanation:
For each answer choice, there are n = 11 numbers mentioned.
The median will be at slot n/2 = 11/2 = 5.5 = 6, so there are 5 values below the median and 5 values above it. In total, we have 5+1+5 = 11 items overall.
The vertical bar in the box plot represents the median's location. It's at 12, so "12" must be in slot 6 in the answer.
Based on this alone, the answer is between choice A or choice C. These two answers are nearly identical except for one thing: the max for choice A is 20 while the max for choice C is 19.
The answer is choice C because the boxplot shown has the tip of the right whisker at 19, and not 20.
Side note: the data values must be sorted before you can find the median. Luckily, for each answer choice, the values are already sorted for us.
Answer:
It would be Choice C

Which polynomial represents the difference below?
(8x2 +9) - (3x2 + 2x + 5)
Step-by-step explanation:
= (8x² + 9) - (3x² + 2x + 5)
= 8x² + 9 - 3x² - 2x - 5
= 5x² - 2x + 4
What transformation has taken place on the coordinate grid pleaseee help my final! I'll give rate and heart etc
Answer:
Translation across the coordinate plane
Step-by-step explanation:
Here, we want to get the kind of transformation that has occurred to the shape
from the given coordinate diagram, we can see that A shifted from (2,3) to (-3,6)
B shifted from (2,-2) to (-3,1)
and C shifted from (-1,-4) to (-6,-1)
If we look at these, we can observe that there is a change in the x-axis coordinate in each by (-1-(-6) or 2-(-3) = 5 units
and there is a change in the y-axis value by (3-6) = -3 units
so the transformation here can be represented generally as;
(x -5, y+ 3)
With this, we can see that what we have represented is simply a translation across the coordinate plane

Question from Venn diagram solving... plz solve. Worth 15 points
Answer:
For this type of problem, it is best to use Venn diagrams as shown in the picture. The areas where the circles intersect are the mutual events that occur together. The area where all circles intersect is denoted as x. These are the students who play all sports. Assuming all of the students play sports in the school, all of the numbers in the circles should add up to 405. The remaining area would be the difference. The solution is as follows:
Students who play tennis and hockey: 45 - x
Students who play hockey and softball: 60 - x
Students who play only tennis and softball: 39 - x
Students who only play tennis:
251 - 45 + x - 39 +x -x = x + 167
Students who only play hockey:
157 - x - 45 + x - 60 + x = x + 52
Students who only play softball:
111 - x - 60 + x - 39 + x = x + 12
The sum of all of these should be 405:
45-x+60-x+39-x+x+167+x+52+x+12 = 405
Solving for x,
x = 30
Therefore, there are 30 pupils who play all sports; 15 pupils who play tennis and hockey; 30 pupils who play hockey and softball; 9 pupils who play tennis and softball; 197 pupil who only play tennis; 82 pupils who only play hockey; and 42 pupils who only play softball.
Step-by-step explanation:
Hope this is correct, if it is wrong then please feel free to critique me and I wil correct my mistake(s). I'm sorry in advance if it is incorrect.
What is the area? Bit confused on this one.
Answer:
x² + 8x + 12
Step-by-step explanation:
see
the length of the entire rectangle = x + 6
breadth of the entire rectangle = x + 2
area of a rectangle = length × breadth
= (x + 6)(x + 2)
= x² + 8x + 12
which is the required polynomial in standard form
Answer:
x^2 + 8x + 12
Step-by-step explanation:
length = x+6
breadth = x+2
ara of rectangle = l*b
=(x+6)(x+2)
=x(x+2) +6(x+2)
=x^2 + 2x + 6x +12
=x^2 + 8x +12

Given 1x) = 10-2x, find f(7).
Step-by-step explanation:
Given that,
f(x) = 10 - 2xWe are asked to calculate the value of f(7).
Substitute the value of x as 7 in the polynomial to find the value of f(7).
→ f(7) = 10 - 2(7)
→ f(7) = 10 - 14
→ f(7) = -4
Therefore, –4 is the required answer.
