Answer:
The slope is -8/3 or -2 2/3
Step-by-step explanation:
Two points are given, and they are (0, 4) and (3, -4).
The formula for slope is change in y over change in x.
In this case, the change in y is -8, since -4 - 4 = -8.
The change in x is 3, since |0 - 3| = 3.
Thus, the slope is -8/3, which is equal to -2 2/3.

The distance between the elementary school and the middle school is 4 miles. On the map, the two locations are One-half inch apart. What is the scale of the map?
1 inch = 8 miles
1 inch = StartFraction 1 over 8 EndFraction mile
One-half inch = 1 mile
4 inches = 1 mile

Need help solving triangle in picture
Answers
Answer:
see explanation
Step-by-step explanation:
Using the sine ration on the left, right triangle
sin35° = \(\frac{opposite}{hypotenuse}\) = \(\frac{a}{8.6}\) ( multiply both sides by 8.6 )
8.6 × sin35° = a , thus
a ≈ 4.93 cm
a + b = 15.7, so
4.93 + b = 15.7 ( subtract 4.93 from both sides )
b = 10.77
-------------------------------------------------------------
Using the cosine ratio on the left, right triangle
cos35° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{y}{8.6}\) ( multiply both sides by 8.6 )
8.6 × cos35° = y , so
y ≈ 7.04 cm
Using Pythagoras' identity on the right, right triangle
c² = b² + y² = (10.77)² + (7.04)² = 115.99 + 49.56 = 165.55
Take the square root of both sides )
c = \(\sqrt{165.55}\) ≈ 12.87 cm

Step-by-step explanation:
Which equation is the inverse of y = 7x2 – 10?
y = StartFraction plus-or-minus StartRoot x + 10 EndRoot Over 7 EndFraction
y = plus-or-minus StartRoot StartFraction x + 10 Over 7 EndFraction EndRoot
x = plus-or-minus StartRoot StartFraction x Over 7 EndFraction + 10 EndRoot
y = StartFraction plus-or-minus StartRoot x EndRoot Over 7 EndFraction plus-or-minus StartFraction StartRoot 10 EndRoot Over 7 EndFraction
A clearer question:
Which equation is the inverse of y = 7x² – 10
The required inverse of the given function is expressed as \(y=\sqrt{\frac{x+10}{7}}\)
Step 1: Replace y with x
x = 7y² – 10
Step 2: Make y the subject of the formula:
7y² = x+ 10
Step 3: Divide both sides by 7
7y²/7 = (x+10)/ 7
y² = (x+10)/ 7
Step 4; Take the square root of both sides
\(\sqrt{y^2} =\sqrt{\frac{x+10}{7} } \\y = \sqrt{\frac{x+10}{7} } \\\)
Hence the required inverse of the given function is expressed as \(y=\sqrt{\frac{x+10}{7}}\)

\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)
Answer:
The answer is 25 degrees
Step-by-step explanation:
If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

8. The difference in length between the many-lined skunk and the prairie skunk is 1.201 centimeters (20.6 - 19.399 = 1.201).
9. The combined length of the racerunner and the New Mexican whiptail is 56.899 centimeters (26.7 + 30.199 = 56.899).

y - y1 = m(x - x1)

Distribute the 5/9

That is the final answer for C. To find F, do this:
C = 5/9F - 17.78
Add 17.78 to both sides
C + 17.78 = 5/9F
Multiply both sides by 9/5 to cancel out the fraction on the left side
9/5C + (9/5)(17.78) = F
F= 9/5C + 32

Answers
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300
