Answer:
m = - 2/3 or
m = - 0.66667.
I don't know which form is simpler.
Step-by-step explanation:
All you want is the slope.
The slope formula is
m = (y2 - y1) / (x2 - x1)
y2 = 7
y1 = 3
x2 = - 2
x1 = 4
My choice of which one is 1 and which one is 2 is totally arbitrary. You could have made y2 = 3 and y1 = 7 and x2 = 4 and x1 = -2
m = (7 - 3) / (-2 - 4)
m = 4 / - 6
m = -2/3 or
m = - 0.6667
Kendall is starting a new small business and working everyday to make it a success. She earned $952 in 7 days. Assume she will continue to earn money as the same rate and write this rate as a fraction with 30 in the denominator.
Answer:
$4080 / 30days
Step-by-step explanation:
In 7 days, Kendall earns $952
In 1 day, she will earn $952 ÷ 7 = $136
Therefore, the rate (r) at which she earns is $136/day. i.e
r = $136/day ---------------(i)
To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;
r = $(136x30) / 30 day
r = $4080/30days
A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of bolts. The sample mean bolt length was centimeters. The population standard deviation is known to be centimeters.
What is the test statistic z?What is the p-value?Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?
Answer:
There is sufficient evidence. A further explanation is provided below.
Step-by-step explanation:
According to the question,
The alternative as well as null hypothesis will be:
[tex]H_0:\mu = 16[/tex]
[tex]H_a:\mu>16[/tex]
The test statistics will be:
⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]
By putting the values, we get
⇒ [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=2.45[/tex]
Or,
The p-value will be:
= 0.0071
i.e.,
⇒ [tex]p-value< \alpha[/tex]
Thus the above is the correct answer.

Step-by-step explanation:
the sum of two numbers is 37 and the greater number is 5 less than twice the Lesser number find the positive intergers
Answer:
x = 14
y = 23
Step-by-step explanation:
x = first number
y = second and greater number
x + y = 37 ⇒ y = 37 - x
y + 5 = 2x
Substitution:
(37 - x) + 5 = 2x
42 - x = 2x
3x = 42
x = 14
y = 37 - (14)
y = 23

A survey of 200 families showed that
75 had a dog;
58 had a cat;
25 had a dog and a cat;
77 had neither a cat nor a dog nor a parakeet;
5 had a cat and dog and a parakeet.
How many had a parakeet only?
Answer:
15 is the answer , the total people who has dogs , cats , parakeets and none is equals to 185 then from 200 you minus 185 which is 15 so 15 people had parakeets only

Answer:
6 1/4
Step-by-step explanation:
When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.
If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.
For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.

If a cube measures 13 cm each and the volume is 2197 what is the surface area of the cube
Answer:
1014 cm^2
Step-by-step explanation:
A cube has 6 congruent square faces. To find the total surface area, find the surface area of one face,a nd multiply it by 6.
SA = 6s^2
SA = 6(13 cm)^2
SA = 6(169 cm^2)
SA = 1014 cm^2

Angel signed up for a streaming music service
that costs $11 per month. The service allows
Angel to listen to unlimited music, but if he
wants to download songs for offline listening, the
service charges $0.50 per song. How much total
money would Angel have to pay in a month in
which he downloaded 25 songs? How much
would he have to pay if he downloaded s songs?
Answer:
Cost for 25 songs: $23.50
Cost for s songs: .50(s) + 11
Step-by-step explanation:
To solve this problem, we can make an equation in slope-intercept form:
y = mx + b
y represents the total amount of $.
m represents the cost of each song downloaded, or $.50
x represents the number of songs, or 's'
b represents the $11, or the constant.
We have the equation:
y = .50(x) + 11
If Angel downloaded 25 songs, we have the equation:
y = .50(25) + 11
We get y = $23.50

Line p passes through points (5,-4) and (2,7). What is the slope of a line that is perpendicular to line p
Answer:
3/11
Step-by-step explanation:
First find the slope of the line
m = (y2-y1)/(x2-x1)
= ( 7 - -4)/(2 - 5)
= (7+4)/(2-5)
=11/ -3
We want a line that is perpendicular, so it is the negative reciprocal
-1 / ( -11/3)
+3/11
A line that is perpendicular will have a slope that is 3/11

What does it mean to have a skewed distribution? What causes a skew in statistical terms? And how does one deal with skewed data when conducting research? Are there specific types of
research questions and types of data where one would expect the data to be skewed?
Answer:
Explained below
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.

Answer:
w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6
Step-by-step explanation:
The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.
