if you plot this on a scatterplot, would the correlation be strong or weak?? EXPLAIN! ( temperature is x and sales is y)

Answers

Answer:

Strong Correlation

Step-by-step explanation:

If the numbers of the sales are matched in order with the temp., this is a strong correlation. I'm assuming the question is asking you to prove the correlation between the change in temperature, and the change in hot chocolate sales.

If you match the numbers, you'll see that when its colder outside, hot chocolate sales go up. When it's hot out side, sales go down. This is a strong, inverse correlation.

Then again, if these numbers are out of order in any way, my entire answer goes down the drain. Make sure all information is included in your question, including pictures :)

BIDMAS so do the 7+3 first = 10
[10 x 5 - 4] (divided by) (2+3)
then work out both brackets by doing the multiplication first
[10 x 5 - 4] = [50 - 4] = 46
(2 + 3) = 5

Answers

Answer:

A regular pentagon

Step-by-step explanation:

A pentagon has 5 sides. There are 5 tick marks.

The answer polygon is a Hexagon.

What is a hexagon?

A hexagon is a six-sided polygon. Hexagon has some special properties when we are talking about inscribed polygons.

Two vertices of the hexagon lie on the corners of the diameter of the circumscribing circle.

Given that, Stella is using her compass and straightedge to complete the construction of a polygon inscribed in a circle.

We are asked which polygon is she in the process of constructing.

Since, there are 6 marks on the circle, which is one of the step for constructing a hexagon.

So, We can say that she is constructing a regular hexagon inside the circle.

Lesson 5 Practice Problems
1. A restaurant offers delivery for their pizzas. The total cost is a delivery fee added to
the price of the pizzas. One customer pays $25 to have 2 pizzas delivered. Another
customer pays $58 for 5 pizzas. How many pizzas are delivered to a customer who
pays $80?
Be sure to completely explain your answer.
When explaining, make it sound like you are talking to a grandma.

Answers

Let the price of a pizza be x
Delivery charge be y
Cost of two pizzas = 2*x
2x+y=25. ————-(1)
Y=25-2x
Cost of 5 pizza = 5*x
5x+y=58. —————-(2)
Substitute y=25-2x in equation 2
5x +25-2x=58
3x+25=58
Subtract 25 from both sides
3x =58-25
3x=33
Divide both sides by 3
X=33/3
X=11
Plug-in x= 11 in equation 1
2*11+y=25
22+y=25
Y=25-22
Y=3
Cost of a pizza =$11
Delivery charge=$3

80-3=77
Number of pizzas delivered=77/11=7


7 pizzas are delivered

Answer:

[tex]\frac{\sqrt6 + 2}{2}[/tex]

Step-by-step explanation:

Hello!

To rationalize the denominator, we want the denominator to be rid of any square root operations.

To do that we have to multiply the whole fraction by the value of the denominator, or multiply it by a Giant 1.

Rationalize:

[tex]\frac{3 + \sqrt6}{\sqrt6}[/tex][tex]\frac{3 + \sqrt 6}{\sqrt6} * \frac{\sqrt6}{\sqrt6}[/tex][tex]\frac{\sqrt6(3 + \sqrt6)}{\sqrt6 * \sqrt 6}[/tex][tex]\frac{3\sqrt6 + 6}{6}[/tex]

Simplify:

[tex]\frac{3(\sqrt6 + 2)}{3(2)}[/tex][tex]\frac{\sqrt6 + 2}{2}[/tex]

Final expression: [tex]\frac{\sqrt6 + 2}{2}[/tex]

Giant 1

A giant one is another term for a fraction that simplifies to 1. To simplify to

one, the fraction's numerator and denominator have to be the same. We

multiplied our expression by √6/√6, which doesn't change the value of the

original expression because we are technically multiplying by 1.

Julio bought 4 tickets to the circus for $12.50 each. He also bought a souvenir for his
son for $4.75. If Julio pays for the tickets and the souvenir with a $100 bill, how
much change will he receive?

Answers

Find the total he spent and subtract that from 100:

12.50 x 4 = 50

50 + 4.75 = $54.75 total spent

100-54.75 = $45.25 change

He would receive $45.25
Example:
12.50 * 4 = $50 + $4.75 = $54.75
100 - $54.75 = $45.25

mixed numbers multiple 4 1/2 x 1 2/3

Answers

Answer:

7 1/2

Step-by-step explanation:

So, we have the problem 4 1/2 x 1 2/3.

Lets convert both of these mixed fractions into improper fraction, because it would be much easier to multiply.

4 1/2= 9/2 as an improper fraction

1 2/3= 5/3 as an improper fraction

Now, lets multiply!

9/2 x 5/3

Lets multiply the numerators first.

9 x 5 is 45

Now, the denominators.

2 x 3 is 6

So, 9/2 and 5/3 is 45/6

Lets convert 45/6 into its mixed fraction form

45/6 as a mixed fraction would be 7 1/2
