Answer:
Percent of change in population is 
%
Step-by-step explanation:
Given population of Boston is 
measured in year 
.
And population of Boston in year 
is 
.
We need to find percent of change in population.
So, percent change 
%
Here old population is and new population is
Plugging these value in formula we get,
Percent change 
Rounding to nearest tenth 2.6%
Answer:
(1) Coeficcient (2) Constant (3) 4 terms (4) In descending order, 2, 1, 3, 4 (5) -2 (6) 1 (7) 5 (8) 2 (9) -15, 5x, -7x^2, 2x^3 (10) -4x^2y, 2xy, 5x, 7
Step-by-step explanation:
Sorry if I got one wrong
The answer is D. It can't be considered a funtion unless each X value only has 1 Y value corresponding to it. In this problem, you see the X value 3 paired with -1 and 1.
75% is 3/4
So if 12 = 3/4, then 1/4 = 4
Therefore, they attempted 16 free throws ✌
Answer: P < 300 = 0.102
Step-by-step explanation:
Suppose the round-trip airfare between Boston and Orlando follows the normal probability distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the round-trip airfare between Boston and Orlando.
µ = mean
σ = standard deviation
From the information given,
µ = $387.20
σ = $68.50
The probability that a randomly selected airfare between Boston and San Francisco will be less than $300 is expressed as
P < 300
For x = 300,
z = (300 - 387.20)/68.5 = - 1.27
Looking at the normal distribution table, the probability corresponding to the z score is 0.102
