Answer:
The predicted GPA is then y = 0.149(15) + 0.89 = 3.125
Step-by-step explanation:
Although you don't specifically say so, the equation you provide here is probably a "best fit" equation based upon data: GPA versus number of hours of study per week.
Here, y = 0.149x + 0.89 and the number of study hours of interest is 15.
The predicted GPA is then y = 0.149(15) + 0.89 = 3.125
Answer:
76,800 subscribers :)
Step-by-step explanation:
Initially: 4,800
3 years: If the number of subscribers is doubling every 3 years, all you have to do is multiply it by 2.
4,800 · 2 = 9,600
So, after 3 years, they have 9,600 subscribers.
6 years: Now that the health blog has 9,600 subscribers, you need to multiply THAT number by 2.
9,600 · 2 = 19,200
Now the blog has 19,200 subscribers
9 years: Now, we just repeat what we've been doing for the other 6 years: multiply the blog's current subscriber count by 2.
19,200 · 2 = 38,400
12 years: Once more and we'll have our answer! Sub count is 38,400. Now double it.
38,400 · 2 = 76,800
Hope this helps! :)
5^9/5^5= 625
You can either change the exponents to their equivalent whole numbers or subtract exponents.
The answer could also be represented as 5^4
Correct histogram: top-right corner
Step-by-step explanation:
The picture is missing: find it in attachment.
A histogram is a type of plot representing data divided into classes. The classes can be represented using bars with same width: if so, the height of each bar is proportional to the number of data inside each class.
Here by looking at the table in the figure, we notice that:
- There are 3 data in the 800-899 class: 805, 805, 872
- There are 5 data in the 900-999 class: 910, 919, 923, 950, 989
- There are 8 data in the 1000-1099 class: 1004, 1010, 1020, 1051, 1056, 1085, 1094, 1098
- There are 6 data in the 1100-1199 class: 1108, 1128, 1133, 1150, 1150, 1187
- There 3 data in the 1200-1299 class: 1209, 1220, 1298
Therefore, the correct histogram representing the set of data is the histogram on the top-right corner, which has respectively columns of height 3, 5, 8, 6 and 3.
