Write an equation that models the bee population (b), (w) weeks after it is first measured. You'll use the variable b for the bee population and the variable w for the weeks after it is first measured.

The required equation that models the bee population (b) is y = 2000x + 500

Equation of a line

The equation of a line in slope-intercept form is expressed as y = mx + b

where;

m is the slope of the line graphb is the y-intercept

Using the coordinate points on the graph (2, 2000) and (3, 4000)

Get the slope of the line

[tex]m=\frac{4000-2000}{3-2}\\m=\frac{2000}{1}\\m=2000[/tex]

Since one of the coordinate points lies on the y-axis at (0, 500), hence the y-intercept is 500.

Elena's distances and times for a training run are given by the equation , where represents distance in miles and represents time in minutes. Who ran faster during the training run?

Answers

Answer:

Elena's run for 1.17 miles in ten minutes

Step-by-step explanation:

From the question

y = 8.5 x ; where x is Distance in miles, and y is time in minutes

and y= 10 minutes

thus on substituting the respected values we get

10 = 8.5 x

⇒ x  = [tex]\frac{10}{8.5}[/tex]  = 1.17 miles

Therefore Elena's run for 1.17 miles in ten minutes

It is a strong positive correlation, and it is likely causal.

Answers

Answer: It is a strong positive correlation,and it is not likely causal.

Step-by-step explanation: Correlation Coefficient value is used to determine the strength of linear relationship between two variables. The value ranges from - 1 to +1.with negative values depicting a negative relationship and positive values showing positive relationship. Value of 0 implies that, no relationship exists. The closer the correlation Coefficient value is to +1 or - 1, the greater the strength of the relationship between them. Also correlation does not mean causation. Hence, a correlation coefficient of 0.74 depicts a strong positive relationship. However it doesn't imply causation.

The given correlation is strong positive correlation,and it is not likely causal.

We have given that,

The correlation coefficient relating the two variables is 0.74.

Answers

Answer: Yes

Step-by-step explanation:

From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.

Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.

question 1 and 2 please :) (exact form)

Answers

Answer:

1. x = 6 cm

2. The coordinates of the x-intercept are (-15.798879, 0) and (8.177004, 0)

b) The maximum value of is y is approximately 459.874

The value of 'x' for which the maximum occurs is x is -3.8109375

c) 'k' is approximately -15.63748 or 'k' is approximately 8.0156

Step-by-step explanation:

1. The area of rectangle ABCD - Area of triangle ABP = 114 cm²

Therefore, we have;

The area of rectangle ABCD = (2·x - 3)·(3·x + 1)

∴ The area of rectangle ABCD = 6·x² + 2·x - 9·x - 3 = 6·x² - 7·x - 3

The area of triangle ABP = 1/2 × (3·x + 1)·x = 3·x²/2 + x/2

The area of rectangle ABCD - Area of triangle ABP = 6·x² - 7·x - 3 - 3·x²/2 - x/2

6·x² - 7·x - 3 - 3·x²/2 + x/2 = 9·x²/2 - 13·x/2 - 3 = 114

9·x²/2 - 15·x/2 - 3 = 114

9·x² - 15·x - 6 - 228 = 0

9·x² - 15·x - 234 = 0

x = (15 ± √((-15)² - 4 × 9 × (-234)))/(2 × 9) = (15 ± 93)/18

∴ x = 6 or x = -13/3

Given that x is a natural number, we have that x = 6 cm

2. The given equation is 'y = -3.2·x² - 24.39·x + 413.4'

Therefore, we have;

The x-intercept are the values of 'x', where the value of 'y' is 0

Therefore, we have, at the x-intercept;

y = 0 = -3.2·x² - 24.39·x + 413.4

By the quadratic formula, we have;

x = (24.39 ± (√((-24.39)² - 4×(-3.2)×413.4)))/(2 × (-3.2))

x ≈ -15.798879 or x ≈ 8.177004

The coordinates of the x-intercept are;

(-15.798879, 0) and (8.177004, 0)

b) The maximum is given at dy/dx = 0

Therefore, at the maximum point, we have;

dy/dx = d(-3.2·x² - 24.39·x + 413.4)/dx = -6.4·x - 24.39 = 0

dy/dx = -6.4·x - 24.39 = 0

∴ x = 24.39/(-6.4) = -3.8109375

x = -3.8109375 at the maximum point

At the maximum point, we have;

y = -3.2·x² - 24.39·x + 413.4 = -3.2·(-3.8109375)² - 24.39·(-3.8109375) + 413.4 ≈ 459.874

y ≈ 459.874

Therefore, the maximum value of 'y' is given as follows

[tex]y_{max}[/tex]  ≈ 459.874

The value of 'x' for which the maximum occurs is x = -3.8109375

c) The coordinate of the point is (12.3, k), therefore, we have;

y = -3.2·x² - 24.39·x + 413.4

When y = 12.3, therefore, -3.2·x² - 24.39·x + 413.4 = 12.3

-3.2·x² - 24.39·x + 413.4 = 12.3

-3.2·x² - 24.39·x + 413.4 - 12.3 = -3.2·x² - 24.39·x + 401.1 = 0

By the quadratic formula, we have;

x = (24.39 ± √((-24.39)² - 4×(-3.2)×401.1))/(2 × (-3.2))

x ≈ -15.63748 or x ≈ 8.015600

Therefore, k ≈ -15.63748 or k ≈ 8.015600

find the measure of the indicated angle ? no l

Answers

The interior angle of any triangle sum to 180° in measure, so that angle ACB has measure

m∠ACB = 180° - 67° - 35° = 78°

Angles ACB and BCD are supplementary because they occur on the same ray AD, which means they also sum to 180° in measure. Then angle BCD has measure

m∠BCD = 180° - 78° = 102°

Answer:

102 degrees

Step-by-step explanation:

for this problem, add the angles given to 180 degrees to find the remaining angle ACB in the triangle. Once you have that angle, you can subtract it from 180 degrees to find BCD, because side ACD is straight. By adding Angle CAB (67 degrees) and Angle ABC (35 degrees), you end up with the missing 98 degrees to reach 180 degrees. thus, when subtracting to find BCD on the straight of ACD, a value of 102 degrees remains for Angle BCD

This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 95 degrees Fahrenheit.C=59(F)1=59(F)(F)=95Since 95 = 1.8, statement II is true.The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 59 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:C=59(F)C=59(59)C=2581(whichis1)An increase of 59 degree Fahrenheit leads to an increase of 2581, not 1 degree, Celsius, and so Statement III is not true.
