Answer:
Step-by-step explanation:
Mean = sum of variables/sample size
Sum of variables = 5+8+18+1+14+6+8+13+8+19
Sum of variables = 100
Sample size = 10
Mean = 100/10
Mean = 10
Median is the value at the centre after rearrangement.
On rearrangement
1,5,6,8),8,8,(13,14,18,19
Median = 8+8/2
Median = 16/2
Median = 8

What is the equation of the line that passes through the point (-1,4) and has a slope of -5?
Answer:
y = -5x + 4
Step-by-step explanation:
In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.
Answer:
y = -5x - 1
Step-by-step explanation:
Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.
Point slope formula = y - y = m(x - x)
m = -5 (-1, 4)
y - 4 = -5(x +1)
y - 4 = -5x - 5
y = -5x - 1
solve for w. need help pls

Let f(x)=x²-x-12 and g(x)= x -4.
What value can the expression (f/g)(x) never equal?
Answer:
7
Step-by-step explanation:
This function can never equal 0. Why? well here:
(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.
However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.

Answer:
x = -5
Step-by-step explanation:
Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.
This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).
So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.
On the right side we are given 9 for AD, and 18 for DC.
9/18 = 0.5
This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:
If AD/DC = 0.5, then BE/EC will also = 0.5
BE = x+23
EC = x+41
Therefore:
[tex]\frac{x+23}{x+41} = 0.5[/tex]
Now we can solve by multiplying both sides by x+41 to eliminate the fraction:
[tex]x+23=0.5(x+41)[/tex]
Now we multiply out the brackets and move the terms to different sides:
[tex]x+23=0.5x+20.5[/tex]
[tex]0.5x = -2.5[/tex]
[tex]x = -5[/tex]
And if we substitute the -5 into the equations:
-5+23 = 18
-5 + 41 = 36
We will see that -5 does indeed give us the same ratio between the lengths:
18/36 = 0.5
Hope this helped!
1) -6 < 3х – 4x
Can some one help me
combine like terms
-6<-1x
divide by negative 1 on both sides
flip the sign when dividing by a negative number
6>x is the answer.
Answer:
[tex]\boxed { x < 6}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]-6 < 3x - 4x[/tex]
-Combine like terms:
[tex]-6 < 3x - 4x[/tex]
[tex]-6 < -x[/tex]
-Switch sides:
[tex]-6 < -x[/tex]
[tex]-x > -6[/tex]
-When you are dividing an integer by a negative integer, then the inequality sign would change. So, to get the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} > \frac{-6}{-x}[/tex]
[tex]\boxed { x < 6}[/tex]

Answer: x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
4(2x + 1) + 2 = 5(x + 6)
8x + 4 +2 = 5x + 30
Collect like terms
8x - 5x = 30 - 4 - 2
3x = 24
Divide both side by 3
x = 8

Please please help asap!!!! Solve for the indicated variable. 3a + 6b = 4 for b
Answer:
b = (4/6) - a/2
Step-by-step explanation:
6b + 3a = 4
6b = 4 - 3a
b. = (4 - 3a)/6
b. = (4/6) - a/2
The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
In the provided expression, variable and constant are there
It is given that:
The equation in a and b, where a and b are the variables:
3a + 6b = 4
Here the indicated variable is b.
To find the value of b in terms of a make the subject as b:
Subtract 3a on both the sides in the equation 3a + 6b = 4:
The equation becomes:
3a + 6b -3a = 4 - 3a
6b = 4 - 3a
Divide by 6 on both sides:
The equation becomes:
6b/6 = (4 - 3a)/6
b = (4 - 3a)/6
Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Please help!! 13 points, will mark brainliest!! How to calculate [tex]cos (x)=\frac{6}{15}[/tex]?
I'm doing a trig question; trying to find angle XYZ, and I think the formula for the answer is C = [tex]\frac{A}{H}[/tex], which as stated in the title, I think in this situation is [tex]Cos(x)=\frac{6}{15}[/tex].
I don't know what I'm doing wrong, or if I've done the whole question wrong, but no scientific calculators will give me an answer because it says Cos is already defined. I know for sure the answer isn't 0.4, which was a guess I made. The entire question is attached below.
Answer:
66.4°
Step-by-step explanation:
Let ∠XYZ be x°.
Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.
[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]
To find the value of x°, take the inverse of cosine.
[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]
Thus, ∠XYZ= 66.4°

The ages of three brothers are consecutive even integers. Three times the age of the youngest brother exceeds the oldest brother's age by 48 years. What is the age of the youngest brother?
Answer:
28 years
Step-by-step explanation:
youngest brother's age = x
middle brother's age = x+2
oldest brother's age = x+4
3(x-2) = (x+2)+48
[simplify]
3x-6 = x+50
[add 6 to each side]
3x = x+56
[subtract x from each side]
2x = 56
[divide each side by 2]
x = 28
Write a fraction for which the sum of the numerator and denominator is 44, and the value of the fraction is 5/6.
Answer: [tex]\frac{20}{24}[/tex]
Multiply each sides of the fraction (numerator/denominator) by 4.
5 x 4 = 20, 6 x 4 = 24
Make a fraction out of 20 and 24.
20/24 = [tex]\frac{20}{24}[/tex]
Make sure the fraction is correct, by adding.
20 + 24 = 44
Answer = 44
AGIAN HELP!!!!Identify the point on the vertical axis (y-axis) and state the real-world meaning of that point.
Answer:
The point on the vertical axis (y-axis) represents the y-intercept.
It represents the height over the sea level at the starting point of hiking
Step-by-step explanation:
From the graph
The y-axis represents the height above the sea level in feetThe x-axis represents the hours hiking→ The point on the vertical axis (y-axis) represents
The initial height above the sea levelThis point is the starting point of hikingIt called the y-intercept (0, 2000)→ Which means it represents their height at 0 hour
→ The real-world meaning of that point is:
They are 2000 feet above the sea level when they decided to start hikingThe point on the vertical axis (y-axis) represents the y-intercept.
It represents the height over the sea level at the starting point of hiking
