Answer:
12a²-14a-48
Step-by-step explanation:
4a(3a-8) + 6(3a-8)
= 12a²-32a+18a-48
=12a²-14a-48
We can combine x + x and get 2x. So we have:
8x - 2y + 2x. Therefore 10x - 2y is equivalent.
Answer:
(b) The distribution of the last digits of ID numbers in a sample of 100 college students
Step-by-step explanation:
<u>Uniform Distribution Explanation</u>
In statistics, uniform distribution refers to a type of probability distribution in which all outcomes are equally likely.
The only possibility here is the distribution of the last digits since the last digit can be 0 thru 9 and each is equally likely to appear in a random sample of 100 students
The others can be eliminated
Heights can vary depending on gender, ethnic background etc. In fact heights will follow a normal distribution
Scores can vary, most students will be scoring around the mean follows a normal distribution
GPAs like scores can vary, most students will have GPAs close to the mean GPA so follows a normal distribution
Answer:
C is the only choice that forms a proportion
Step-by-step explanation:
a. 24/31, 20/27
(31 is prime)
b. 8/9, 24/36
(this one doesn't work since it would have to be 3/4) which isn't a proportion
c. 16/5, 64/20
(both 16/5 *4 = 64/20) so it works
d. 6/4 , 15/10
(similar situation to choice b the ratio wont work since 6 doesn't go into 15)
Answer:
-
- The cost of surfing the web at the café for one hour:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Take two points and substitute them into the formula for calculate the slope (The formula is 
).
Having these points:
and 
You can identify that:
Then, the slope is:
Substitute the slope and the coordinates of any point on the line into the equation and then solve for "b":
Therefore, equation in Slope-Intercept form that represents the function is:
Since 1 hour hour has 60 minutes, you need to substitute 
into the equation and then evaluate, in order to find the cost of surfing the web at the café for one hour. Then:
