What is Temperature?
The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined various reference points and thermometric substances.
The following information is provided for hot chocolate sales and outside temperatures:
(Y) Sales Temperature (X)

422 68
235 89
199 91
(A)
Attached below is the scatter plot.
(B)
A cluster is a group of points or values gathered in one location.
A cluster of three values between the temperatures of 80°F and 100°F may be seen on the scatter plot.
A value that differs significantly from the other values in a data set is referred to as an outlier. Either it's too little or it's too big.
In the given data collection, there is an outlier.
The anomalous value is (189, 16°F).
(C)
The scatter plot's points have a decreasing slope.
This suggests that the variables temperature and sales have a bad relationship.
There is a bad association as a result.
(D)
Dependent variables are variables that are being studied, or being kept an eye on for any changes while the other variables in the model are altered.
The variables that are changed to cause the dependent variable to vary proportionately are known as independent variables.
According to the outside temperature, the data in this case shows the sales of hot chocolate.
Sales are therefore the dependent variable, and temperature is the independent variable.
This is due to an increase in hot chocolate sales as the temperature drops.

The probability of a promotion, given that a salesperson missed the quota: B is
The probability of no promotion, given that a salesperson missed the quota: C is
The probability that a salesperson hit the quota and got promoted: D is
V
Done
The probability that a salesperson hit the quota, given that the salesperson was promoted, using the tree diagram,: is option c 0.86
What is a probability?
The probability of an event in an experiment is calculated by the division of the number of desired outcomes by the number of total outcomes in the experiment.
From the tree diagram, there are two ways to obtain the promotion:
0.41 of 0.68 (hit the quota).
0.14 of 0.32 (did not hit the quota).
Hence the probability of getting a promotion is:
P(A) = 0.41 x 0.68 + 0.14 x 0.32 = 0.3236.
The probability of both getting a promotion and hitting the quota is:
P(A and B) = 0.41 x 0.68 = 0.2788.
Hence the conditional probability is:
P(B|A) = P(A and B)/P(A) = 0.2788/0.3236 = 0.86. (approximately).
The probability that a salesperson hit the quota, given that the salesperson was promoted, using the tree diagram,: is option c 0.86

NASA launches a rocket at t = 0 seconds. Its position (height), in meters above sea-level, as a function
time, t, is given by s(t): - 4.9t2 + 187t + 192. Use this position function to answer the following
questions. Round solutions to three decimal places, if necessary.
The rocket splashes down after 39.164 seconds. The rocket reach its peak height 19.081 seconds after launch. The rocket peaks at 1976.13 meters above sea level.
The function of height is given by,
h(t) = -4.9t² + 187t + 192
Once the rocket will be splashed down in sea, means the height of the rocket will be zero. Means
x h(t) = 0
-4.9t² + 187t + 192 = 0
Solving the quadratic equation with quadratic formula, we have two values of t
t = 39.164 and t = -1.001
We will consider the positive value of the time
So the answer is 39.164 seconds.
For getting the maximum value, we should differentiate the function of height and make it equal to zero.
[tex]\frac{dh(t)}{dt} = \frac{d}{dt} (-4.9t^2 + 187 t + 192)[/tex]
For maximum value of h, [tex]\frac{dh (t)}{dt} = 0[/tex]
0 = -4.9 × (2t) + 187
t = 19.081 seconds
At this time, the height of rocket will be maximum.
So putting the vaiue in the given function.
h = -4.9 × (19.081)² + 187 (19.081) + 192
h = 1976.13 meters

A toaster oven usually sells for $60. If the toaster oven is 20% off, and sales tax is 7%, what is the total price of the toaster oven, including tax?
The total price of the toaster oven, including tax is $51.36.
How to calculate the value?Given that the toaster oven usually sells for $60 and the toaster oven is 20% off, the new price will be;
= Normal price - Discount
= $60 - (20% × $60)
= $60 - $12
= $48
Also, sales tax is 7%, therefore the new price will be:
= $48 + (7% × $48)
= $48 + $3.36
= $51.36
The price is $51.36.

The end behavior of the given graph is as x → -∞, f(x) → ∞ and as x → ∞ f(x) = ∞.
End behavior of graph
End behavior of the graph refers the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. And the degree and the leading coefficient of a polynomial function will determine the end behavior of the graph.
Given,
Here we have the graph with some function as y = f(x).
Here we have to find the end behavior of the graph.
Here we can see that the value of x goes to the positive side (the right side of the graph), the graph increases upwards, and this is shown with the arrow pointing up.
So, which means that the value of x goes to ∞, then the value of y will also go to ∞.
Similarly, we can see the exact same behavior for the negative side of x (the left side of the graph), then as x goes to -∞, y will go to ∞.
Therefore, the correct option will be the second option, counting from the top.

1. Find the measure of <6.
2. Find the measure of <4.
Answer:
1=180 2=90
Step-by-step explanation:
1=∠1 and ∠2 are supplementary, so m∠2 = 180° - x°. ∠2 and ∠6 are corresponding angles. So, m∠6 = 180° - x°.
2=Their measures are equal, so m∠4 = 90 . When two lines intersect to form one right angle, they form four right angles.
Answer:
∠4 = 55°
∠6 = 35°
Step-by-step explanation:
Finding the unknown angles:In ΔABC,
35 + 90 + ∠4 = 180° {Sum of all angles of triangle}
125 +∠4 = 180
∠4 = 180 - 125
∠4 = 55°
Linear pair: If in two adjacent angles, the non-common arms form a straight line, then the two angles are called linear pair and they add up to 180.
∠7 + ∠8 = 180° {linear pair}
90 + ∠7 = 180°
∠7 = 180 - 90
∠7 = 90°
In ΔACD,
∠6 + ∠4+ ∠7 = 180 {Sum of all angles of triangle}
∠6 + 55 + 90 = 180
∠6 + 145 = 180
∠6 = 180 - 145
∠6 = 35°

B) angle A+ angle B+ angle C+ angle D=180^
C) angle A+ angle B+ angle C+ angle D=360^
D) AR = CD
Answer: B
Step-by-step explanation:
What is an isosceles trapezoid?
An isosceles trapezoid is a type of quadrilateral in which the non-parallel sides have equal length and angle measure.
Let's address each answer to see which are true:
A) True: By definition of an isosceles trapezoid, the non-parallel sides have equal length and angle measure. 2x+10 and 4x-30 are written as equations to represent the unknown measurement of the angles A and D. Because this is an isosceles trapezoid, these angles would have the same measurement, meaning they are equal to each other.
B) False: A trapezoid is a quadrilateral. Quadrilaterals are four-sided figures which angles add up to 360°. Some other shapes that are quadrilaterals are squares, rectangles rhombuses and trapezoids. Because a trapezoid is a quadrilateral, the angles do not and can not add up to 180°
C) True: A trapezoid is a quadrilateral, which is a shape which angles add up to 360°. This means that Angles A, B, C, D of this shape should also add up to 360°.
D) True: An isosceles trapezoid is a type of trapezoid whose non-parallel sides have equal side lengths and angles measurements. Due to this definition, AB and CD would have the same length.

The legend on a map states that
1 inch is 500 miles. If you measure
8 inches on the map, how many
miles would the actual distance be?
The actual distance will be 4000 miles.
According to the question,
We have the following information:
The legend on a map states that 1 inch is 500 miles.
So, this statement can be rewritten in the form of following expression:
1 inch = 500 miles
Now, in order to find the actual distance for 8 inches, we will multiply the distance in 1 inch with 8.
(More to know: measurements like this are used in daily life to find the actual distance between two places.)
So, we have the following expression:
8 inches = 500*8 miles
8 inches = 4000 miles
Hence, the actual distance will be 4000 miles if it measures 8 inches on the map.

can somebody please help me
Answer: D
Step-by-step explanation: I believe this the correct answer. If you start by looking at the "right 3 units", going right on a coordinate plane is - and left is +, so right 3 units is -3. Then, down 4 units is -4 (on coordinate plane, up is + and down is -).
So then, plug it into the equation: h(x)= {x-3}-4
I hope this helps and you get it right :)

Answer:
-35
Step-by-step explanation:
If 2 is added to a number and the sum is tripled, the result is 16 more than the number. Find the number.
Using simplification, the number is −1.
Given that, If 2 is added to a number and this sum is tripled, the result is 4 more than the number.
Let the number is x.
Therefore from given information we get
2 is added to a number.
Then it is x+2.
Sum is tripled.
So 3(x+2)
4 more than number means x+4.
So according to the given statement equation should be
3(x+2)=x+4
Simplifying the expression
3x+6=x+4
Subtract 6 on both side
3x+6−6=x+4−6
3x=x−2
Subtract x on both sie
3x−x=x−2−x
2x=−2
Divide by 2 on both side we get
x=−1
Hence, the number is −1.

Newton earns $39 for working 3 hours as a radio host.
What is meant by time and work?In terms of time and work, it refers to how long it takes a person or group of individuals to perform a task and how well each of them does it. A crucial concept that time and labour have in common with other arithmetic topics is the concept of proportionality. Efficiency is inversely proportional to time required while the amount of work is constant.
Efficiency serves as the proportionality constant, and work and time are directly proportional.
Given,
As a radio host, Newton puts in 15 hours and makes $195..
For a one hour the employee earns $13
