A regression equation for this line is y = -0.42x + 19.26 a. What do the slope and y-intercept indicate? The slope indicates that the percent in 1985 should have been about 19%. The y-intercept indicates that the percent is falling at about 0.4% each year. b. The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%. The slope indicates tha the percent has remained the same for each year. The y-intercept indicates the percent in 1985 should have been 22%. d. There is not enough information to determine what the slope and y-intercept indicate.
Answer:
B.The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%.
Step-by-step explanation:
A regression equation is it this form:
Y' = b0 + b1X
I am going to identify the slope and intercept in this equation to help us go further in our solution.
b1X is the slope. The slope usually has an x value multiplied to it
b0 is the intercept.
Back to our question, the equation in this question is
Y = -0.42X + 19.26
The slope is -0.42X.
The y intercept is 19.26
The slope has a negative sign, this shows us that the percentage is falling by about 0.4% every year while an intercept of 19.26 tells us that percentage in 1985 should have been about 19%.

What is an equation in point-slope form of the line that passes through (-7, 1) and (-3, 9)?
writing the linear equation can be used by any any of those coordinates that are given
y - y1 = m(x - x1)
m = Gradient
Making m the subject of the formulam = y - y1 / x - x1
Where:
(-7, 1) = (x, y)
(-3, 9) = (x1, y1)
Solving for mm = (1 - 9) /( -7 + 3)
m = -8/- 4
m = 2
Inputing this into our point slope form equation : y - y1 = m(x - x1)
We have:
y - 9 = 2(x + 3)
Therefore, Option D is the correct option

Starting with x=0.811, express x as a fraction in the simplest form
Show steps plz
Answer:
811/1000
Step-by-step explanation:
x =0.811
Step 1
Multiply both numerator and denominator by 1000
x = 0.811/1 × 1000/1000
= 811/1000
Therefore, x as a fraction in the simplest form is 811/1000

The profit function, P(x) , revenue function, R(x), and cost function, C(x), are related by the equation P(x)=R(x)-C(x) . Manuel has determined that the revenue and cost functions for a new product line at his business are given by these functions. R(x)=3x C(x)=600+2x. What is the profit function in standard form for Manuel's new product line
Answer:
P(x) = 5x - 600
Step-by-step explanation:
Given
Cost function C(x) = 600+2x
revenue function R(x) = 3x
If the profit function is related by the equation
P(x)=R(x)-C(x)
P(x)= 3x - (600-2x)
open the parenthesis
P(x) = 3x - 600 + 2x
P(x) = 3x+2x - 600
P(x) = 5x-600
Hence the profit function in standard form for Manuel's new product line is P(x) = 5x - 600

30 point question! WILL AWARD BRAINLIEST!
A ball is thrown across a playing field from a height of h = 5 ft above the ground at an angle of 45° to the horizontal at the speed of 20 ft/s. It can be deduced from physical principles that the path of the ball is modeled by the function
y = − (32/(20^2))x2 + x + 5
Find the horizontal distance the ball has traveled when it hits the ground. (Round your answer to one decimal place.)
Answer:
Answers are down below ;)
Step-by-step explanation:
y = − (32/(20^2))x2 + x + 5
Plug into the calculator: -32/20^2 = -.08x^2
Find the maximum height attained by the ball:
Rewrite the equation:
y= -.08x^2 + x +5
This parabola is a negative meaning that it will be maximum
to find the maximum we use the formula -b/2a
-(1)/ 2 (-.08) = -1/ -.16= 6.25
we plug 6.25 back into the equation y= -.08(6.25)^2+ (6.25) +5 = 8.125
The maximum height attained by the ball: 8.125 feet
Find the horizontal distance the ball has traveled when it hits the ground.
This can be found with the quadratic equation, x = [-b ± √(b2-4ac)]/2a
a= -.08 , -b= -1, c= 5 (When you are plugging in the numbers, make sure to break them down).
-(-1)± √(-1)^2-4(-.08)(5)] 2(-.08) -->
[-1 ± √(1 + 1.28)]/-.16 = [-1 ± √(2.6)]/-.16 = [-1 ± 1.61]/-.16 =
The horizontal distance of the ball is x = 16.31 feet

The probabilities that stock A will rise in price is 0.42 and that stock B will rise in price is 0.58. Further, if stock B rises in price, the probability that stock A will also rise in price is 0.14. a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)
Answer:
0.92
Step-by-step explanation:
a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)
P(A) = 0.42
P(B) = 0.58
P(A|B) = 0.14
Step 1
P(A|B) × P(B) = 0.14 × 0.58
= 0.0812
The probability that at least one of the stocks will rise in price
P(A) + P(B) - 0.0812
0.42 + 0.58 - 0.0812
= 1 - 0.0812
= 0.9188
Approximately to 2 decimal place = 0.92

Answer:
To the nearest hundredth, this has a value of 0.01
Step-by-step explanation:
To find the proportion of the population change accounted for by Florida population, we just need to divide the population change for Florida by the population change in the entire country;
Mathematically, that will be ;
218929/27323632 = 0.008012441391393
