Answer:
The integer which represents the change in temperature from morning to afternoon is -11°
Step-by-step explanation:
Since the morning temperature in Erin's apartment was 79°, and the temperature in Erin's apartment that afternoon was 68°. If Erin turned up the temperature and the temperature in the afternoon was 68°. So, the temperature change from 79° down to 68° is thus 68° - 79° = -11°.
So, the integer which represents the change in temperature from morning to afternoon is -11°

[tex] {3x}^{2} - x + 4 = 0[/tex]
Answer:
[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex] or [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]
Step-by-step explanation:
Use the quadratic formula.
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-1) \pm \sqrt{(-1)^2 - 4(3)(4)}}{2(3)} [/tex]
[tex] x = \dfrac{1 \pm \sqrt{1 - 48}}{6} [/tex]
[tex] x = \dfrac{1 \pm \sqrt{-47}}{6} [/tex]
[tex] x = \dfrac{1}{6} \pm \dfrac{i\sqrt{47}}{6} [/tex]
[tex] x = \dfrac{1}{6} + \dfrac{i\sqrt{47}}{6} [/tex] or [tex] x = \dfrac{1}{6} - \dfrac{i\sqrt{47}}{6} [/tex]
State whether the data described below are discrete or? continuous, and explain why. The volumes left parenthesis in cubic feet right parenthesis of different rooms Choose the correct answer below. A. The data are discrete because the data can take on any value in an interval. B. The data are discrete because the data can only take on specific values. C. The data are continuous because the data can take on any value in an interval. D. The data are continuous because the data can only take on specific values.
Answer:
The correct answer is:
The data are continuous because the data can take on any value in an interval. (C)
Step-by-step explanation:
Discrete data are data that can take on certain limited values. There is a limit to what values can be assigned to such data. For example, the number of children in a school will just be whole numbers, either 20 or 50 or 55 or 108, etc, you cannot have 100.5 children. This makes it limited to the values it can take on, hence it is discrete
Continuous data, on the other hand, are data that can take on any value within a scale. The possibility of assigning a value is unlimited. for example height. The height can be 3m, 3.8m, 4.57m, etc, there's no limit to the possibility that a height can take. Other examples are; temperature, weight, acceleration, volume etc. In this example the volume of a room in cubic feet can be 30ft³, 50.6ft³, etc. The possibilities are endless, hence it is a continuous data.
Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P,P, in terms of x,x, representing Cooper's total pay on a day on which he sells xx dollars worth of computers.
Answer:
P= 0.015x+60
Step-by-step explanation:
thats the right answer
If Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Then P = 0.015x + 60 is total pay.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Cooper's base pay is $60 per day
He gets $60 even for not selling computers,
meaning P= 60 when x=0, which is the y-intercept.
Now if Cooper makes a commission of 1.5% for all sales,
His earning will be increased by 1.5%.
The percentage value should be changed to decimal value. By Dividing 1.5 by 100
1.5/100=0.015
The amount of money earned in a given day increases $0.015 for each $1 of sales made.
Here x, representing Cooper's total pay on a day on which he sells x dollars of worth computers.
P = 0.015x + 60
Hence P = 0.015x + 60 is the total pay of cooper .

(60)x = 1, what are the possible values of x? Explain your answer.
Answer:
[tex]\frac{1}{60}[/tex]
Step-by-step explanation:
Problem:
The possible values of x in the equation (60)x = 1;
Solution:
Such a problem like this in which the highest power of the unknown is 1 will have just one solution.
60x = 1
To solve this, we take the multiplicative inverse of 60;
the multiplicative inverse of 60 = [tex]\frac{1}{60}[/tex]
Use this inverse to multiply both sides of the expression;
[tex]\frac{1}{60}[/tex] [tex]x[/tex] 60x = 1 x [tex]\frac{1}{60}[/tex]
x = [tex]\frac{1}{60}[/tex]
what is the difference between the mean and the median of the set ( 3 ,8 ,10 ,15)
Answer:
You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example, you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.
Step-by-step explanation:
Mean) 3+8+10+15=36, 36/4=9 ANSWER=9
Median) 8+10=18, 18/2=9 ANSWER=9
In the case, the mean and median are the same and depending on context you could choose either method. It also helps that there is no outlyer. If there were on I would recomend finding the median.

△DEF and △FGH similar right triangles. The coordinates of all the vertices are integers. The relationship between the slope of DF¯¯¯¯¯ and the slope of FH¯¯¯¯¯¯ cannot be determined, because the triangles are congruent. The slope of DF¯¯¯¯¯ is less than the slope of FH¯¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for DF¯¯¯¯¯ than for FH¯¯¯¯¯¯ . The slope of DF¯¯¯¯¯ is equal to the slope of FH¯¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for DF¯¯¯¯¯ as for FH¯¯¯¯¯¯ The slope of DF¯¯¯¯¯ is greater than the slope of FH¯¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for DF¯¯¯¯¯ than for FH¯¯¯¯¯¯ .
Answer:
Congruent triangles are triangles with the same sides and the same measure of angles. You are given triangle DEF which is similar to triangle FGH. From the figure, side FH is larger than side DF. So the statement of them being congruent cancels out. Triangle DEF is smaller in size than triangle FGH. So they are not congruent. The slope is defined as the rise overrun. Side DF has the same slope as side FH. Sides DE and FE are proportional to sides FG and HG. Only C and D are correct.

Johanna can type 120 words in 3 minutes. Using the same unit rate, how many words can
she type in 10 minutes?
Answer:
600 words.
Step-by-step explanation:
If Johanna can type 120 words in 3 minutes, and the problem is asking us to find how many words she can type in 10 minutes at the same unit rate, we'll have to start by solving how many words she can type in 1 minute:
[tex]\frac{120}{3}[/tex]
Dividing 120 words into 3:
[tex]=60[/tex] words per minute.
Now that we know how many words Johanna types in one minute (per minute), we can multiply the words per minute by 10 (minutes):
[tex]60[/tex] × [tex]10=600[/tex] words in 10 minutes.
_
We can check our work by dividing 600 words into 10 minutes to see if we achieve the same unit rate of 60 words per minute:
[tex]\frac{600}{10}[/tex]
[tex]=60[/tex] words per minute.
Since we have the same unit rate, our answer is correct!
