If the mean of the data set is 32.6. Then the number of pages he read in 5 days is 163.
<h3>What is Mean?</h3>
Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.
Han recorded the number of pages that he read each day for five days.
If the mean of the data set is 32.6 pages. Then the total number of the pages he read till now, will be
Let the total number of the pages be x. Then we have

Answer:
x-int:(-2,0)(-4,0) . y-int:(0,8)
Step-by-step explanation:
y = x2+6x+8 and y = (x+2)(x+4)
x-int:
x+2=0
x= -2
(-2,0)
x-int:
x+4=0
x=-4
(-4,0)
y-int: plug 0 for x
y=(0+2)(0+4)
y=8
(0,8)
3/4 = 0.75
10.5 / 0.75 = 14 samples can be made.
Answer:
y = 1
x = -2
Step-by-step explanation:
During the substitution method, you are substituting one function into another. Because both functions are set equal to "x", you can make the functions equal each other. This allows you to 'get rid' of the "x" variable and simplify to find the value of "y".
5A) x = -2y
5B) x = 2 - 4y
-2y = 2 - 4y <----- Set both equations equal
2y = 2 <----- Add 4y to both sides
y = 1 <----- Divide both sides by 2
Now that you know what "y" equals, you can plug that value into the "y" variable into one of the equations. This will allow you to then simplify and find the answer for "x".
x = -2y <----- Equation 5A
x = -2(1) <----- Plug 1 into "y"
x = -2 <----- Multiply -2 and 1
It's w + 15. As it is increasing by 15, 15 is added onto it.
