Answer:
Here is a similar question attached with.
Option (b) that is 2005 is the right choice.
Step-by-step explanation:
Given:
An equation in slope intercept form.
Where 
= number of years
Comparing from the standard slope intercept form.
y-intercept value 
According to the question the predicted winning speed 
mph
Plugging the value of 
in slope intercept form, we will calculate the (number of years) and then we will add this with 
.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Finally the year would be 
So in year 2005 the winning speed is predicted to be 7.16 mph.
Answer:
Length of side of square
Step-by-step explanation:
Sides of rectangle
let be diagonal of rectangle
<u><em>Pythagorean theorem : The square of hypotenuse is equal to sum of square of sides.</em></u>
Here hypotenuse 
Diagonal of square 
let side of square
again use pythagorean theorem
X=-29/3y+14
hope this helps
Using the Pythagorean Theorem:
Missing side = √4^2 +8^2
Missing side = √16+64
Missing side = √80 = 8.9 (rounded to the nearest tenth)
Answer:
a. 0.80
b. $80
Step-by-step explanation:
a. The expected value, E(Y) is the sum of: [(each of the possible outcomes) × (the probability of the outcome occurring)]. In more concrete terms, the expectation is what you would expect the outcome of an experiment to be on average:
Hence the expected value E(Y) is 0.80
b. From a above we have the expectation as E(Y)=0.80.
-The expected amount is calculated by multiplying expectation by the surcharge:
Hence, the expected amount of surcharge is $80
