Q: The table shows the weights of apples at a grocery store. If this represents a proportional relationship, what is the weight of 12 apples? Remember to explain your answer :)

Answer:

6.9x

Step-by-step explanation:

2.7x + 3.2x + x     =     So you combine like terms. Since they all have x after them, they are all like terms so you can add them all together. x = 1

Therefore, your answer is 6.9x

Answer: it went up 25%

Step-by-step explanation: if it would have went up 50%, that would be $20, meaning it would be $60. It is 25% and it is half of 50% and half of $20 is $10 equaling $50

Answer:

1st question: y=7x-51

Step-by-step explanation:

So for the first question: *aHem*

You rewrite the equation to be 5=7*8+b. The reason why is because since it will be parellel it will have the same slope, and those coordinates that you gave me I just plugged into equation.

Solve equation: 7*8=56 so now it's 5=56+b. Subtract 56 from both sides. -51=b

Rewrite again into y=7x-51. The reason why is because b means y intercept and you are looking for where to start (y-intercept) and keeping the same slope. Parallel means never touching.

Answer:

  58.7 °F

Step-by-step explanation:

At 5000 feet, the airplane is 5 times 1000 feet above the ground, so the temperature will have dropped 5 times 1.2 °F.

  64.7 - 5×1.2 = 64.7 -6.0 = 58.7

At 5000 feet, the temperature is 58.7 °F.

Answer:

the college should hire a new statistician

Step-by-step explanation:

In statistics correlation is a measure of the linear relationship between two variables.

How closely related the two variables are gives the strength of the relationship.

Positive correlation occurs when an increase in the value of one variable results in an increase in the value of the other.

Negative correlation is when there is an inverse relationship. That is an increase in one variable results in a decrease in the other.

In the given scenario where there is a statistical analysis between exam grades and scholastic achievement, the relationship between them should be a positive one.

The higher the exam grades a student gets the higher his scholastic achievement.

However it is stated that correlation is -1.08. This implies an inverse relationship, which is not correct.

So the college should hire a new statistician who can give more accurate analysis

Answer:

The distance on a number line between -9 and -5 would be 4. This is kinda easy.

Step-by-step explanation:

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. The distance between -9 and -5 on a number line is 4 units.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

On a number line, the distance between any two points can be found by subtracting one number from another, then taking its absolute values of it.

Therefore, the distance between -9 and -5 on a number line can be written as,

Distance = |-9 - (-5)|

             = |-9 + 5|

             = |-4|

             = 4

Hence, the distance between -9 and -5 on a number line is 4 units.

A fact family is made up of three numbers. Just as in any family the members, or numbers, are related and there are always at least four math facts to be made with them. Take, for example, these members of a fact family: 6, 4, and 10.

In the family 6, 4, and 10 they are related because you can add two of the numbers to get the last number.

6 + 4 = 10

You can also switch the first two numbers, using the commutative property of addition, and still get the same answer.

4 + 6 = 10

Just find how they can relate! Hope it helps!

Answer:

3 times 6 = 18             2 times 5 = 10

6 times 8 = 18             5 times 2 = 10

18 divided by 6 = 3    10 divided by 2 = 5

18 divided by 3 = 6    10 divided by 5 = 2

Answer:

10,440

Step-by-step explanation:

12/100=x/87,000

you are trying to solve for x because you want to know what is 12% of 87,000 so you need to cross multiply to get

12 times 87,000 = 100x

1,044,000=100x

then divide by 100 to get

=10,440

Answer:

g= 1/3 hr + 1/3 x

Step-by-step explanation:

Solving for G

Step 1: Add x to both sides.

3g − x + x =hr+x

3g = hr+x

Step 2: Divide both sides by 3.

3g/3 = hr+x/3

g= 1/3hr + 1/3x

Answer:

[tex] \rm g = \dfrac{1}{3}(rh + x) [/tex]

Step-by-step explanation:

Solve for g:

[tex] \longrightarrow [/tex] 3g - x = rh

Add x to both sides:

[tex] \longrightarrow [/tex] 3g + (x - x) = rh + x

x - x = 0

[tex] \longrightarrow [/tex] 3g = rh + x

Divide both sides by 3:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3} g = \dfrac{1}{3}(rh + x) [/tex]

[tex] \rm \dfrac{3}{3} = 1: [/tex]

[tex] \longrightarrow [/tex] [tex] \sf g = \dfrac{1}{3}(rh + x) [/tex]

The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance

Null hypothesis is accepted at 0.05 level of significance

A company has developed a training procedure is significantly improve scores

Step-by-step explanation:

Step(i):-

Given  sample mean (x⁻ )  = 517

sample standard deviation (s) =90

Mean of the Population (μ) =500

Null Hypothesis :- H₀ :   (μ) =500

Alternative Hypothesis : H₁ :  μ ≠ 500

Step(ii):-

Test statistic

                         [tex]t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }[/tex]

                        [tex]t = \frac{517 -500}{\frac{90}{\sqrt{100} } }[/tex]

                        t  =   1.717

Level of significance

                      ∝ = 0.05

                    t₀.₀₅ = 1.6604

The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance

Conclusion:-

Null hypothesis is accepted at 0.05 level of significance

A company has developed a training procedure is significantly improve scores
