Answers

Answer 1
Answer: The correct answer for the question that is being presented above is this one: "A. positive nonlinear association." The association best describes the data in the table is that it is A. positive nonlinear association given the table
Variable x 1 9 3 5 5 8 2.5 4 6 
Variable y 1 0 66 80 38 89 100 108 24 
Answer 2
Answer:

Answer:

Option: C is correct (No Association)

Step-by-step explanation:

We are given a table of values as:

Variable x 1 9 3 5 5 8 2.5    4     6  

Variable y 1 0 66 80 38 89 100   108    24

The linear association is such that the scatter plot is linear i.e. the points seems to be in line.

and it is positive or negative depending whether the points are increasing or decreasing.

From the scatter plot we could clearly see that there is no association as:

  • There are two values corresponding to 5.
  • The points are neither increasing continuously nor decreasing.

Hence, option: C is correct.

0.14m= how many cm. get it right please

Answers

Here, I'll show you an EASY conversion acronym:
Kangaroos, Hopping Down Mountains Drinking Chocolate Milk:
That is KHDMDCM.
Now, here's what they ACTUALLY stand for:
Kilo, (kilometers, kilograms, etc.), Hecto, (hectograms, hectometers, etc.), Deca, (decameters, decagrams, etc.), M stands for THREE things, Meters, liters, and grams, Deci, (decimeters, decigrams, etc.), Centi, (centimeters, centigrams, etc.), and Milli, (millimeters, milligrams, etc.).
Now, you look at the diagram I have provided below:
You put 0.14 under Meters, liters, and grams, because it's 0.14 meters.
Now, whenever you move RIGHT, you move the decimal RIGHT every time you move. If there is a WHOLE number, (like 14), you add a ZERO to the number, so when you would move 14 to the RIGHT, it would become 140. Now when you go LEFT, you move the decimal to the LEFT, and if there are ANY ZEROS, you would take them out.
Now you might get a little confused when moving left;
Look, EVERY NUMBER has a decimal, like the number 14 itself.
14 has an imaginary decimal, which is 14.0. EVERY NUMBER HAS THAT. So, if you are moving LEFT, and you DON'T have any zeros, you would simply have 14 into 1.4.
So, with that out of the way, let's start figuring out how many centimeters 0.14 is equivalent to.
So we move to the RIGHT, because the centimeters is on the RIGHT, and now we move the decimal to the right.
Now it would be 01.4, but it's the same as 1.4, so we'll just put 1.4 under deci.
Now we have 1.4 DECIMETERS, but not quite yet centimeters.
We must keep moving to the right.
Once we move that decimal AGAIN, it is now 14. 
WOO HOO! WE FIGURED IT OUT!
So 0.14m = 14 cm.
You saw how we figured that out? You could use this technique on ANY conversion problem like this in the future!
I hope I helped! =D
In a simpler way than the other answer, the answer is 14 cm. This is because there are 100 cm in a meter. So to work this out just multiply 0.14 by 100 to work out the answer. The answer is now 14.

the diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm multiply answer a 134.8 b 185.6 c 218.4 d 269.6

Answers

Answer:

Surface Area of the juice box = 269.6 cm²

Step-by-step explanation:

The dimensions of the box in shape of rectangular prism is given by :

6.4 cm × 4 cm × 10.5 cm

⇒ Length = 6.4 cm

Width = 4 cm

Height = 10.5 cm

Surface Area of rectangular prism is given by the formula = 2(wl + hl + hw) ,where w = width, h = height and l = length

⇒ Area of rectangular prism shaped box = 2(4×6.4 + 10.5×6.4 + 10.5×4)

                                                                    = 2(25.6 + 67.2 + 42)

                                                                    = 2 × 134.8

                                                                    = 269.6 square cm

Hence, Surface Area of the juice box = 269.6 cm²

Therefore, The correct option is D. 269.6

Answer

Surface Area of the juice box = 269.6 cm²

The dimensions of the box in shape of rectangular prism is given by :

6.4 cm × 4 cm × 10.5 cm

⇒ Length = 6.4 cm

Width = 4 cm

Height = 10.5 cm

Surface Area of rectangular prism is given by the formula = 2(wl + hl + hw) ,where w = width, h = height and l = length

⇒ Area of rectangular prism shaped box = 2(4×6.4 + 10.5×6.4 + 10.5×4)

                                                                   = 2(25.6 + 67.2 + 42)

                                                                   = 2 × 134.8

                                                                   = 269.6 square cm

Hence, Surface Area of the juice box = 269.6 cm²

Therefore, The correct option is D. 269.6

Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50. Write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit, b, Harper can buy.

Answers

Answer:

4.75x + 3.75y ≤ 15 inequality models the given situation.

Harper can buy at maximum 3  bags of fruits.

Step-by-step explanation:

 Given : Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50.  

We have to write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit that  Harper can buy.

Let Harper buys 'x'  bags of fruit

and 'y'  box of crackers

Given : cost of one bags of fruits is $ 4.75

so the cost of x bags of fruits is 4.75x

Given : cost of one box of cracker is $ 3.50

so the cost of y box of crackers is 3.75y

also, Harper has $15.00 to spend at the grocery store

So the maximum amount he can spend is $15

So inequality become,

4.75x + 3.75y ≤ 15

So the maximum number of bags of fruit Harper can buy.

is when he buys no box of cracker.

Put y = 0 in above inequality , we have,

4.75x + 3.75(0) ≤ 15

4.75x  ≤ 15

Divide both side by 4.75

We have , x = 3.158 ≈ 3

So , Harper can buy at maximum 3  bags of fruits.
since harper has only %15 that is the most she can spend, therefore we would have 15> or = 4.75b+3.5c.  the best way to solve this would be to divide 15 by 4.75, then round down to the nearest whole number. if you do this, you get 3 bags of fruit.

Can someone simplify this please!! (3.1)⋅(10.75−3.55)

Answers

Answer:

Simplification of the expression (3.1)⋅(10.75−3.55) is:

22.32

               

Step-by-step explanation:

We have to simplify:

(3.1)⋅(10.75−3.55)

(3.1)⋅(10.75−3.55)=(3.1)·(7.2)

                          =22.32

Hence, on simplifying the expression (3.1)⋅(10.75−3.55) , we get:

22.32

                     

(3.1)*(10.75-3.55)=
(3.1)*(7.20)
=22.32 :)
