Step-by-step explanation:
3.6 ➗ 0.09 the other way is to put the numbers in fractions
36/10 ➗ 9/100
Answer:
b. 2/15
c. 7/15
Step-by-step explanation:
total frequency = 45
X 0 1 2 3 4 5 6 7
P(x) 1/45 7/45 2/45 1/15 4/45 1/9 2/15 7/45
b. P(≥4) = 18/45 = 2/5
c. P(<3) = 21/45 = 7/15
Answer:
y = 1.0535(4.9512)^x
It can be considered a viral video
Step-by-step explanation:
Using the exponential regression calculator, the regression model obtained is :
y = 1.0535(4.9512)^x
Using the model, we can determine if a video can be considered viral ;
Number of days, x = 10
y = 1.0535(4.9512)^10
y = 1.0535(8853290.1338)
y = 9,326,941.15
Hence, video will receive way over 3 million reviews, a review of about 9,326,941, hence, it can be considered a viral video.
To solve this, you already have the y value of the coordinate, which is 3, and the x value is represented by a. Plug the values into your graph equation so that it looks like this: 3=2a-5
Then, add 5 to both sides to isolate 2a:
8=2a
Finally, divide both sides by 2 to get that a=4
Hope this helps!
Keep in mind that whenever you have a variable inside an expression, you have to think of it as a placeholder, hiding a certain value which we haven't specified yet.
Expressions with variables are a mean to express the generic idea underneath the expression, rather than its particular value.
So, an expression like x-7 represents the idea of subtracting 7 from a particular number. Once you give a specific value to x, the expression will become an actual subtraction between numbers, and you will be able to compute its value.
So, we have several values for x, which are several ways to turn our "abstract" subtraction into an actual, computable subtraction.
