Answer:

2/5

Step-by-step explanation:

2 divided by 5 is 0.4 which is greater than .35

Answer:

0.35  <  2 /5

Step-by-step explanation:

Simplifying then comparing both terms  0.35  and  2/ 5 .

0.35  is less than  0.4  which means that the first term is less than the second term.

Answer:

The answer would be x=7.5

Step-by-step explanation:

Answer:

x=7.5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2.45+5.5x−4.3x=1.3+0.7x

−2.45+5.5x+−4.3x=1.3+0.7x

Step 2: Combine Like Terms

(5.5x+−4.3x)+(−2.45)=0.7x+1.3

1.2x+−2.45=0.7x+1.3

1.2x−2.45=0.7x+1.3

Step 3: Subtract 0.7x from both sides.

1.2x−2.45−0.7x=0.7x+1.3−0.7x

0.5x−2.45=1.3

Step 4: Add 2.45 to both sides.

0.5x−2.45+2.45=1.3+2.45

0.5x=3.75

Step 5: Divide both sides by 0.5.

0.5x/0.5=3.75/0.5

so

x = 7.5

Answer:

parallel

Step-by-step explanation:

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:

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.

Answer:

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.

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:

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

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
