At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
Answer:
y = (1/2)x + 25 or y = 0.5x + 25

I used a online calculator that is reliable.
A construction company is building the house show below. They need to use a scale of 1 in: 8f. They measured the drawing to find that that the height of the building is 2.5 in. Explain to the construction workers how they would use this information for calculate the height of the final building.
I need help asap and no links please
Answer:
They would have to multiply 2.5in and 8 ft because the ratio is 1in:8ft and the inches go up and you have to keep the ratio at the same value so you multiply 2.5 and 8

Answer:
Angle A = 48
Step-by-step explanation:
The steps are in this order
1. (3y+22) + (4y) = 106
2. 7y +22 = 106
3. 7y = 84
4. y = 12
Then check the answer
5. 4(12) =
6. 48
7. 3(12) + 22
8. 36 + 22
9. 58

Explain why you divide by 2 for triangles and why you divide by 3 for pyramids
Answer:
triangles are half a rectangle/square. So thats why you divide by 2. diving by 2 is also multiply by 1/2.
pyramids are in 3 dimensions, so since they are like half, but in three dimensions, you divide by 3, in other words multiply by 1/3.

Which of the following questions is a statistical question?
What is the top-selling board game?
In what aisle are the board games located in the local store?
How many board games require a deck of cards to play?

Answer:
The question that is a statistical question would be:
"How many board games have you played in the past month?"
Step-by-step explanation:
A statistical question is defined as a question that can be answered by collecting data that vary. Basically, it is a question that can be surveyed. The question, "How many board games have you played in the past month?", is the only one that is statistical because multiple different answers can be given to this question.

Match the questions with the correct answers about the given box plot below
Answer:
1. D
2. E
3. B
4. C
5. A
5. F
Step-by-step explanation:
The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.
Hope this helps you!
Answer:
Florida: The weight range = 10
Tennessee: The interquartile range = 4
Tennesse: Median Weight = 76
Florida: Median Weight = 80
Florida: Weight of the heaviest child = 84
Tennesse: Weight of the smallest child = 71
Step-by-step explanation:
Florida: How to find the weight range
The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.
R = xn − x1
Therefore, the weight range in Florida is 10
Tennessee: How to find the interquartile range
To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
Q1 = 74
Q2 = 78
78 - 74 = 4
Therefore, the interquartile range in Tennesse is 4
Tennesse: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 75.5
Therefore, the median weight of Tennesse is 76
Florida: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 79
Therefore, the median weight of Florida is 80
Florida: Weight of the heaviest child
Since the smallest number in Florida is 84,
Therefore, the weight of the heaviest child in Florida is 84
Tennesse: Weight of the smallest child
Since the smallest number in Tennesse is 71,
Therefore, the weight of the smallest child in Tennesse is 71

Can someone please help me find the measure of the exterior angle.
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180° because they are supplementary angles
k = 140°
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180°
k = 140°
