63 40 51 70 36 21 51 28 19 find the mean of data
Answer:
42.11
Step-by-step explanation:
Add all of the numbers, and then divide the total of the numbers by 9. With 9 being how many numbers are added.
The mean of the given data set is approximately 42.11.
To find the mean of a set of data, you need to sum up all the values and then divide the sum by the total number of values.
Given the data: 63, 40, 51, 70, 36, 21, 51, 28, 19
Here, there are 9 values.
Add up all the values:
63 + 40 + 51 + 70 + 36 + 21 + 51 + 28 + 19 = 379
Divide the sum by the total number of values:
379 / 9 = 42.11
Therefore, the mean of the given data set is approximately 42.11.

Troy plans to paint a solid cube that has an edge of 10 feet long. What is the total area of the surface Troy will paint?
Answer:
Surface Area=600ft
Step-by-step explanation:
If 10ft is the edge each side has an area of 100ft. Since its a cube it has 6 sides so you time 6 and 100 which gets you 600.
Let g(x)= - 3x and h(x) = x^2 – 5. Find (g o h)(0).
Answer:
15
Step-by-step explanation:
(g o h)(0) = g of h of 0 = g (h(0))
1. Find h(0)
h(0) = 0^2 - 5 which equals -5
2. Find g(-5)
g(-5) = -3 • -5 which equals 15

VIEW ATTACHED PHOTO!! Is the pictured graph growth, decay, or linear or none?
a.) Growth
b.) Decay
c.) Linear
d.) None
domain and range of 10x - 2y = 4
Answer:
domain: (-∞,∞)
range: (-∞,∞)
Step-by-step explanation:
You need to convert this into a linear equation (y=mx+b)
So we add 2y and divide by 2 to get y by itself
that gives us 5x-2=y
If you pictures this graph in your head you'll see that the domain and range are all real numbers
need help with this.

4. 13x + 5y = -11
13x + 11y = 7
Solution:
Answer:
y=2/3
Step-by-step explanation:
Answer:
(-2,3) x= -2 y=3
Step-by-step explanation:
The first thing you should do is convert both into standard y=mx+b form
For the first equation you subtract 5y and add 11 to both sides to get
13x+11= -5y
you divide by negative 5 to get
-13x/5-11/5=y
For the second equation we subtract 11y and 7 from both sides to get
13x-7= -11y
divide both sides by -11 to get
-13x/11 + 7/11
We then set both equations equal to each other and solve for x
-13x/5-11/5= -13x/11 + 7/11
Add 11/5 to both sides to get
-13x/5 = -13x/11 + 156/55
Add 13x/11 to both sides to get
-78/55x=156/55
Divide and solve for x to get -2
Then plug x = -2 into the original equations to find y
13*-2 + 5y = -11
-26 + 5y = -11
Add 26 to both sides
5y= 15
y =3

a zoo has a total of 8 lions and tigers. the number of tigers are one less than twice the number of lions. write a system of equations that represents the number of lions and tigers
A. L + T = 2
T=L-8
B. L-T=8
T=2L-1
C. L+T =8
T=2L-1
D. L+T =8
T= 2L +1
Step-by-step explanation:
Let the number of lions be represented by L
Let the number of tigers be represented by T
A zoo has a total of 8 lions and tigers :
[tex]L + T= 8[/tex]
The number of tigers are one less than twice the number of lions. :

Hannah completed 1/5 of a worksheet in 1/4 of an hour,
how long will it take her to finish one worksheet
Answer:
75 minutes or 1 hour and 15 minutes.
Step-by-step explanation:
First, we need to figure out what 1/4 of an hour is. If an hour is 60 minutes, 60/4 is 15. So we know it will take 15 minutes to complete 1/5 of the worksheet. All we have to do now is multiply 15 by 5 and get 75 OR 1 hour and 15 minutes.

Pete's dad usually deposits $25 into his account every week, and he wants the extra amount deposited to be the same each week. Which inequality and solution show how much more he can deposit each week and keep the total of his deposits above $500 for those 8 weeks?
Answer : 8(25+x) >500 ; x>37.5
Step-by-step explanation:
Given,
Usual deposit per week= $25
Let x be the extra amount.
New amount will be= 25+x ( per week)
Amount need to be deposited 8 weeks = 8(25+x)
As per given,
[tex]8(25+x)>500[/tex] [Required inequality]
[tex]\Rightarrow\ (25+x)>\dfrac{500}{8}\\\\\Rightarrow\ x>\dfrac{500}{8}-25[/tex]

Guys plz help me solve this question I’ve been trying for the past 40 minutes.
Answer:
x= -1.8
Step-by-step explanation:
4x-22=9x+2(1-4x)
2(1 - 4x)
so you have to distribute
new equation
4x-22=9x+2-8x
you combine like terms on the right
9x + 2 -8
+8. +8
17x+2
new equation
4x-22=17x+2
-4x. -4x
-22=13x + 2
-2. -2
-24=13x
-24÷13= - 1.8
X= -1.8
Answer:
[tex]4x - 22 = 9x + 2 - 4x \\ - x = 24 \\ x = - 24[/tex]
A right angle intersects a line at point M. A right angle intersects a vertical line at point M and forms 3 angles. From top to bottom going clockwise, the angles are 1, 90 degrees, 2. Which statement is true about angles 1 and 2? They are congruent. They are right angles. They are complementary. They are supplementary.
I've attached an image showing the intersection and the angle.
Answer:
C: They are complementary
Step-by-step explanation:
We can see from the image that angle 1, angle 2 and 90° are on a straight line. We know that sum of angles on a straight line is 180°. Thus;
∠1 + ∠2 + 90° = 180°
Rearranging, we have;
∠1 + ∠2 = 180° - 90°
Thus;
∠1 + ∠2 = 90°
Now, from angle proofs in trigonometry, it states that If the non-common sides of two adjacent angles add up to 90°, then it means that the angles are complementary.
In our problem here, sum of ∠1 and ∠2 equals 90°. Also, they are the non-common sides of 2 adjacent angles. Thus, we can say that they are complementary.
