Answer:
14 buses and 5 vansStep-by-step explanation:
Let the number of buses be x and vans be y.
Equations as per given:
x + y = 1925x + 7y = 385Substitute y and solve for x the second equation:
y = 19 - x25x + 7(19 - x) = 38525x - 7x + 133 = 38518x = 385 - 13318x = 252x = 252/18x = 14Then finding y:
y = 19 - 14 = 5The answer is 14 buses and 5 vans

The table representing the linear function is attached below.
A linear function is defined as the relation between two variables . A linear function represents a straight line on the number plane.
A linear function is of the form y = mx + c , where m is the slope of the function and c is the y-intercept of the function.The slope is defined as the tangent of the angle made by the line with the positive x-axis.The y-intercept is the point of intersection of the line and the y-axis.Given the slope of the function as 5 and the y-intercept as 20 .
So m = 5 and c = 20
Therefore the linear function is of the form : y=mx + c
Substituting the values we get: y = 5x + 20
Now
at x=0 , y = (5 ×0) + 20 = 20
at x=-4 , y = (5 × -4) + 20 = 0
at x= 4, y = (5 × 4) + 20 = 40
at x= 8, y = (5 × 8) + 20 = 60
Therefore the table for the linear equation is attached.

Find the circumference and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if
necessary.
The area and circumference of a circle is 40.8cm² and 22.6 cm respectively
Circumference of a circleThe formula for calculating the circumference of a circle is expressed as:
C = 2πr
where
r is the distance between A and B
AB = r = √(5-2)²+(3-1)²
r = √9 + 4
r = √13
r = 3.605
Determine the circumference
C = 2(3.14)(3.605)
C = 22.6394
Hence the circumference of the circle is 22.6 cm
Determine the area
Area = πr²
Area = 3.14 * 3.605 * 3.605
Area = 40.8cm²
Hence the area and circumference of a circle is 40.8cm² and 22.6 cm respectively

Rice yield prediction with Simple Linear Regression A simple linear regression is fitted to predict the yield of rice (kg per hectare) by using the annual rainfall (in mm) during the year. The intercept and slope of the regression equation are 473 and 5, respectively. What is the predicted rice yield if the annual rainfall is 582 mm? Choose an answer The predicted rice yield is: 2274 kg. Per hectare 1667 kg. Per hectare 3383 kg. Per hectare 2356 kg. Per hectare
Answer:
3383 Kg per hectare
Step-by-step explanation:
Given that:
Intercept and slope for a given regression equation is :
Intercept = 473 ; slope = 5
The dependent variable / predicted variable = rice yield (y)
The independent variable / predictor variable = annual Rainfall (x)
The regression model can be written has :
General form of a regression equation / model:
y = mx + c ; m = slope ; c = intercept
y = 5x + 473
predicted rice yield if the annual rainfall is 582 mm
y = 5(582) + 473
y = 2910 + 473
y = 3383 Kg per hectare

Your friend first multiplies each side of 1/2 (x-9)=3/4 (5x+1) by 4 when solving the equation. Why might your friend do this?
Answer:
x = (-39)/11
Step-by-step explanation:
Solve for x:
x - 9 = (3 (5 x + 1))/4
Multiply both sides by 4:
4 (x - 9) = (4×3 (5 x + 1))/4
(4×3 (5 x + 1))/4 = 4/4×3 (5 x + 1) = 3 (5 x + 1):
4 (x - 9) = (3 (5 x + 1))
Expand out terms of the left hand side:
(4 x - 36) = 3 (5 x + 1)
Expand out terms of the right hand side:
4 x - 36 = (15 x + 3)
Subtract 15 x from both sides:
(4 x - 15 x) - 36 = (15 x - 15 x) + 3
4 x - 15 x = -11 x:
-11 x - 36 = (15 x - 15 x) + 3
15 x - 15 x = 0:
-11 x - 36 = 3
Add 36 to both sides:
(36 - 36) - 11 x = 36 + 3
36 - 36 = 0:
-11 x = 3 + 36
3 + 36 = 39:
-11 x = 39
Divide both sides of -11 x = 39 by -11:
(-11 x)/(-11) = 39/(-11)
(-11)/(-11) = 1:
x = 39/(-11)
Multiply numerator and denominator of 39/(-11) by -1:
Answer: x = (-39)/11

There is a spinner with 12 equal areas, numbered 1 through 12. If the spinner is spun
one time, what is the probability that the result is a multiple of 5 and a multiple of 2?
Answer:
1/12
Step-by-step explanation:
There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.
