What is the mean of the values in the dot plot?
Enter your answer in the box.
Answers
Answer:
The mean is 46.
Step-by-step explanation:
To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.
40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50
Multiply what's in the parentheses.
40 + 82 + 45 + 96 + 147 + 50
Add, going from left to right
122 + 45 + 96 + 147 + 50
167 + 96 + 147 + 50
263 + 147 + 50
410 + 50
460
Now, divide that by how many dots there were (10).
460/10
The mean of the values in this dot plot is 46.

What is the slope of y = -4?
Answers
Answer:
0
Step-by-step explanation:
The line is horizontal.
Explanation:
Think of y = -4 as y = 0x+(-4)
We see that the equation matches the form y = mx+b
m = 0 = slope
b = -4 = y intercept
Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.

96 is 3/4 of what number?
Answers
Answer:
72.00
Step-by-step explanation:
3/4 x 96 = 72.00
96 is 3/4 of the number 128 , this we get by forming an equation 3/4 × x = 96 and solving for x.
To find the number that 96 is 3/4 of, you can set up a simple equation. Let's denote the unknown number as "x."
According to the given information, we have the equation:
3/4 × x = 96
To solve for x, we need to isolate it on one side of the equation.
Multiplying both sides of the equation by the reciprocal of 3/4, which is 4/3:
(4/3) × (3/4) × x = (4/3) × 96
On the left side, the 3/4 and 4/3 cancel each other out, leaving just x:
x = (4/3) × 96
Evaluating the right side of the equation:
x = 128
Therefore, 96 is 3/4 of the number 128.

Answer: D: 17.3
Step-by-step explanation:
I believe its D because the house and the ground is a 90 degree angle, and at 60 degree angle is a 20 foot ladder. alright then 90 plus 60 = 150 degrees.
then add the twenty foot ladder with each choice for the answer:
A: 20 + 6.1 = 26.1
B: 20 + 10.0 = 30
C: 20 + 14.1 = 34.1
D: 20 + 17.3 = 37.3
The answer would be D because it is the closer number to 150. Because it says " which is the closest height up the house the ladder reaches?" The answer is D the closest number. I HOPE THIS HELPS YOU! =D
