11 times the sum of a number and 15
11 * (x+15)
11(x+15)
the answer is D.
Answer: see image
<u>Step-by-step explanation:</u>
Draw the line y = 1. Count how many units away the point is from that line. Move that point the same number of units in the opposite direction to create the reflection.
J is 2 units above y = 1. The new point is 2 units below y = 1. → (3, -1)
K is 3 units above y = 1. The new point is 3 units below y = 1. → (6, -2)
L is 5 units above y = 1. The new point is 5 units below y = 1. → (3, -4)
M is 3 units above y = 1. The new point is 3 units below y = 1. → (0, -2)
Answer:
Step-by-step explanation:
Let the numbers be y, y+2, y+4
3(y+2)=153
3y+6=153
3y=153-6
3y=147
y=49
y+2=51
y+4=53
Answer:
C. The mean increases by 0.75.
Step-by-step explanation:
The mean of a data set is given by the sum of all its values, divided by the number of values.
Data set {10, 2, 8, 9, 5, 2, 6}
7 values
Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42
Mean: 42/7 = 6
Adding number 12 to the data set
Now we have 8 values
The sum is 42 + 12 = 54
The mean is 54/8 = 6.75
This means that the mean increases by 0.75.
Ok so I'll demonstrate in programming language python.
import math
def circle():
r = float(input("Enter r: "))
a = math.pi * r ** 2
print("Area of circle with r = {0} is {1
}cm2".format(str(r), str(a))
circle()
