Luis's math teacher plots student grades on their weekly quizzes against the number
of hours they say they study on the pair of coordinate axes and then draws the line of
best fit. What is the meaning of the x-value on the line when y = 75?
Answer:
In the graph, we have a linear fit of the student's grades as a function of the number of hours they say that they study.
Then the y-axis represents the grade, and the x-axis represents the number of hours of study, and because this is a linear fit, we will have something like:
y = a*x +b
If we input a value of x here (number of hours studied) we would get the expected grade for the weekly quiz y.
In this situation, the meaning of the x-value on the line when y = 75 would be the (adjusted) number of hours studied to get a grade of 75.
So this x-value is the average number of hours that a student needs to study to get a grade of 75 points.
3/12 anyone. Answer pls and the other questions are 12/28 27/45 10/15 36/48 6/16
Step-by-step explanation:
Pretty much got to find the highest common factor (HCF) then divide it.
3/12=1/4. (3×4=12)
12/28=3/7 (HCF=7)
27/45= 3/5 (HCF=9)
10/15=2/3 (HCF=5)
36/48=6/8=3/4 (HCF=6 then 2)
6/16=3/8 (HCF=2)
A football field is a rectangle measuring 300 ft by 160 ft. each unit on a coordinate grid represents 1 foot. (0,0) and (0,160) are two of the coordinates of a football field drawn on the grid.What are the coordinates of the other two weeks?
Answer: (300,0), (300,160)
Step-by-step explanation:
Given
Dimension of the football field is [tex]300\ ft\times 160\ ft[/tex]
The length between (0,0) and (0,160) coordinates is 160 ft
Similarly, (0,0) and (300,0) represents the 300 ft of length
and (0,160) and (300,160) represents the 300 ft of length
Thus, the other two coordinates are (300,0) and (300,160)

The ratio of the number of Baskin Robbins :Cold stone ice cream cones sold in a day is 11:9.If the number of Baskin Robbins cone sold is 44 .(a)How many cold stone cones are sold ? (b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?
pls answer fast plsssssssssss
Answer: A. 36
B. 5:11
Step-by-step explanation:
(a)How many cold stone cones are sold?
Let the number of stone colds sold be represented by x.
Therefore, we can form an equation as:
11/9 = 44/x
Cross multiply
11 × x = 44 × 9
x = (44 × 9)/11
x = 36
The number of stone cold sold are 36.
(b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?
The new ratio will be gotten as:
= 20/44
= 5/11
= 5:11
The ratio is 5:11

Given that x = 9.2 m and θ = 15°, work out AC rounded to 3 SF
Answer:
AC ≈ 9.52 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos15° = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{9.2}{AC}[/tex] ( multiply both sides by AC )
AC × cos15° = 9.2 ( divide both sides by cos15° )
AC = [tex]\frac{9.2}{cos15}[/tex] ≈ 9.52 m ( to 3 sf )
Find all the missing elements.
Round to the nearest tenth.
a = 5
b = 2
C = 6
A= [?]°
B = [ ]
C = [ ]
Answer: A= 51.3 B= 18.2 C=110.5
Step-by-step explanation:
The missing elements in the triangle are A ≈ 3.992°, B ≈ 170.008°, and c ≈ 5.4 units
To find the missing angle 'A', we can use the law of cosines, which states that for any triangle with sides 'a', 'b', and 'c' and opposite angles 'A', 'B', and 'C', the following relationship holds:
c² = a² + b² - 2ab * cos(C)
Plugging in the known values, we get:
c² = 5² + 2² - 2 * 5 * 2 * cos(6)
Now, we can solve for 'c':
c² = 29 - 20 * cos(6)
c² ≈ 28.8178
c ≈ √28.8178
c ≈ 5.4 (rounded to the nearest tenth)
Now that we have the value of side 'c', we can find angle 'A' using the law of sines, which states that for any triangle:
sin(A) / a = sin(C) / c
Plugging in the known values:
sin(A) / 5 = sin(6) / 5.4
Now, solve for 'sin(A)':
sin(A) = 5 * sin(6) / 5.4 sin(A) ≈ 0.0698
Now, find the value of angle 'A' using the inverse sine (sin⁻¹) function:
A ≈ sin⁻¹(0.0698)
A ≈ 3.992° (rounded to the nearest tenth)
Finally, to find angle 'B', we can use the fact that the sum of angles in any triangle is 180 degrees:
B = 180 - A - C
B = 180 - 3.992 - 6
B ≈ 170.008° (rounded to the nearest tenth)

Answer:
It would be option 2.
Step-by-step explanation:
This is because option 1 does not have a irrational number that goes on indefinitely, option three has the square root of 25, which equals 5 meaning it is rational, and the last option also gives us rational choices. Therefore, the only possibility is that it would be option 2.

how to do compound and simple interest
Answer:
We can compute simple interest by finding the interest rate percentage of the amount borrowed, then multiply by the number of years interest is earned. Another type of interest calculates interest on both the money initialy deposited as well as the interest money earned, and is called compound interest.
