Answer:
y = 50x+40
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
First find two points on the line
(0,40) and (2 ,140)
The slope is
m= (y2-y1)/(x2-x1)
= (140-40)/(2-0) = 100/2= 50
The y intercept is where it crosses the y axis which is 40
y = 50x+40

The _________ in the usage of words may be a serious barrier to effective communication

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9
She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference?
Answers
Answer:
Yes
Step-by-step explanation:
Because the mean is the total of all the words divided by the number of pages, so if the mean is higher, that means that there are more pages on average in the art book than the science book.
Answer:
no

Bartholemew will draw with replacement 160 tickets at random from a box with five tickets [0, 0, 0, 1, 2]. Estimate the chance that the ticket with the 1 on it turns up on exactly 32 draws. Show your work. Please round your answer to the nearest whole percent. (Do not write the % sign, just the whole number.)
Answers
Answer:
0.0786
Step-by-step explanation:
It is given that Bartholemew had drawn the replacement of 160 tickets.
There are five tickets = [0, 0, 0, 1, 2]
Now we need to find the estimate of the ticket that has 1 on it and it turns up on the 32 draws exactly.
Since the probability of the drawing 1 out of 5 tickets is given by, [tex]$\frac{1}{5} = 0.2$[/tex]
So the binomial with the parameter of n = 160 and p = 0.2, we get
P (it turns up on exactly 32 draws) = P(X = 32)
Therefore,
[tex]$C(160, 32)\times (0.2)^{32}\times (0.8)^{160-32}$[/tex]
= 0.0786
A 30 ft ladder is leaning against a wall making a 48 angle with the ground. Approximately how far from the wall is the base of the ladder?
Answers
Based on the type of triangle below we are going to use Trigonometry ratios.
We are going to use the Sine ratio, which is opposite over hypotenuse.
Let opposite be x, hypotenuse be 30 and theta (angle) be 48 deg.
Sine 48 = x/30
Make x the subject
x = 30 Sine 48
Just go ahead and lunch this in a calculator.
x = 22.3 ft
Therefore the distance of the wall from the base of the ladder is 22.3 ft
Which coordinate point represents the y -intercept of the equation 3x + 2y = 18
Answers
Answer:
(-6,18)
Step-by-step explanation:
3x + 2y = 18
2y= -3x + 18
y=-3/2 x + 18
give x=0
y=-3/2 *0+18
y=18#
y=18
3x+2(18)=18
3x+36=18
3x=18-36
3x=-18
x=-18/3
x=-6

There are so many types of angles, let's see what we've got here!
--(5x - 17) and 48 are alternate interior angles, which means that they are congruent.
--(5x - 17) and y are supplementary angles.
--48 and y are same-side interior angles, which means that they are also supplementary.
Let's solve for x first.
5x - 17 = 48
5x = 65
x = 13
Now, let's solve for y.
48 + y = 180
y = 132
