Answer:
Step-by-step explanation:
Let's first find the exponential function that models the situation in year one. The exponential standard form is
where a is the initial value and b is the growth/decay rate in decimal form. If it is growth it is added to 100% of the initial value; if it is decay it is taken away from 100% of the initial value. We are told that the number of cars in year one was 80 million, so
a = 80 (in millions)
If b is increasing by 10%, then we are adding that amount to the initial 100% we started with to give us 100% + 10% = 110% or, in decimal form, 1.1
The model for our situation is
where y is the number of cars after x years goes by. We want to find the difference between years 3 and 2, so we will use our model twice, replacing x with both a 2 and then a 3 and subtracting.
When x = 2:
and
y = 80(1.21) so
y = 96.8 million cars
When x = 3:
and
y = 80(1.331) so
y = 106.48 million cars
The difference between years 3 and 2 is
106.48 - 96.8 = 9.68 million cars
Answer:
Step-by-step explanation:
Alright, lets get started.
When two secants intersects outside a circle then the measure of the angle formed is half of the positive difference of the measures of the intercepted arcs. (Please refer the diagram I have attached)
Hence the measure of ∠1 is :
∠1=
∠1=
hence the answer is 35°. : Answer

Answer: $65 lol
Step-by-step explanation:
Answer:
22/3
Step-by-step explanation:
Make the whole number turn into a fraction, (21/3) and add the numerator (1/3), which the answer would be 22/3
Answer:
b. MLR.3 - No perfect collinearity assumption
Step-by-step explanation:
There is an assumption that nothing in the error term should correlate with the explanatory variable (x) of interest and outcome variable of (y). It does not allow any linear relation between two or more variables. If there is a relation between the variable it the the violation of this assumption.
