Answer:
b-4.2<-7.5
Step-by-step explanation:
b-4.2<-7.5
this is because the number given as "b" minus 4.2 (as shown on the left) is less than (<) -7.5, so this inequality makes sense.
Answer:
The y-intercept for this equation makes no sense for this model.
Step-by-step explanation:
In this case, the explanatory variable x is the year when the observations were taken. So, the values are the integer numbers between (and including) 1975 and 1986.
The<em> y-intercept for the equation of the linear regression makes no sense for this prediction</em>, for it would correspond to the value x=0 (the year 0) is not consider in the range of the explanatory data.
Answer:
8.1
Step-by-step explanation:
Area of a triangle = ½ × base × height = Area
Rearranged =
area/1/2xheight
The base is the length.
8.91/1/2x2.2
=8.1 inches
3x10^5
+3x10^4
+7x10^3
+0x10^2
+6x10^1
+0x10^0
The first step to solving this problem is to write an equation to express the parameters of the problem. The equation is expressed as this:

You can arrive at this equation by taking the ratio of 2 bike rentals and 1 skate rental and adding up the sum of all the purchases.

This makes x equal to making 2 bike rentals and 1 skate rental. If we solve the original equation for x, the result is 5.838. Since we need to be above 362 dollars, we can round up to x = 6. This translates to 12 bike rentals and 6 skate rentals. Finally, we arrive at the answer of 6 skate rentals.
