Answer:
x = 2
y = 8
Step-by-step explanation:
-x - y = 6
5x - 7y = 66
-x - y = 6
x = -y - 6
5x - 7y = 66
5 ( -y - 6 ) - 7y = 66
-12y - 30 = 66
-12y = 96
y = -8
x = -y - 6
x = 8 - 6
x = 2

If a cantaloupe that weighs 3.0 pounds costs $3.87, approximately how much will a 2.22 pound cantaloupe cost?
Answer:[tex]1.29 * 2.22 = 2.86[/tex]
$2.86
Step-by-step explanation:
First we need to find the price per pound for the cantaloupe
[tex]3.87/3.0=1.29[/tex]
So one pound of cantaloupe costs $1.29
Now multiply the price per pound by the weight of the second cantaloupe
[tex]1.29*2.22=2.86[/tex]
So the price for a cantaloupe that weighs 2.22 lbs would be $2.86
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

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.

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.

a school class went on a field trip to see a magician perform. there were 17 females and 20 males in the class. the magician randomly selected a volunteer from the audience, which had 52 females and 68 males. given that the randomly selected audience member is a student from the class, which equation can be used to find the probability, p, that the person is also a female?
An equation that can be used to find the probability, p, that the person is also a female given that the randomly selected audience member is a student from the class is: P = (17/120) ÷ (37/120)
For given question,
The audience of the magic show is conformed by a total of 120 people, 52 of which are female and 68 are men.
Within the audience there is a school class of 37, of these students, 17 are female and 20 are male.
First we find the probability of selecting a student from the class in all audiences.
P(A) = 37/120
Now, the probability that the selected student is female student:
P(B) = 17/120
We need to write an equation for combined probability which is given by,
P = (17/120) ÷ (37/120)
Therefore, an equation that can be used to find the probability, p, that the person is also a female given that the randomly selected audience member is a student from the class is: P = (17/120) ÷ (37/120)

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
