Which of the following expressions are equivalent to 6.53−(−4.11)+7.92

Answer:

mean 4.86

MAD = 1.91

Step-by-step explanation:

The required week that had greater variability in high temperature is week 2.

Given that,
The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius.
The second week had a mean high temperature of 4.86 degrees Celsius and a mean absolute deviation (MAD) of 1.91 degrees Celsius.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
The system of observation that has a higher mean absolute deviation, will have the chance of greater variability in high temperature. So,
mean absolute deviation of week 1 = 1
mean absolute deviation of week 2 = 1.91
MAD of week  2 > MAD of week 1

Thus, the required week that had greater variability in high temperature is week 2.

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

That's

Slope of the through points

(15, -6) and (-3, 13) is

Since the lines are parallel their slope are also the same

So slope of parallel line = - 19/18

Equation of the line using point (4,2) and slope -19/18 is

We have the final answer as

Hope this helps you

Answer:y=-1.583x-8.332

Step-by-step explanation:

First find slope from two points (-6-13)/(15+3)=-1.583

Now line is parallel so the slope would be same for the other line passing through (4,2) now as the general equation of line is

y=mx+c

2=-1.583(4)+c

Solving for c equals to -8.332

So final equation is

y=1.583x-8.332

Answer: Population parameter

Step-by-step explanation: The parameter can be defined as a numerical value used to describe an entire population. The population describes all the entire values or members belonging to a particular group. Hence, numerical values which are used to explain the characteristic of the population is called the population parameter. Sample statistics on the other hand are numerical values associated statistical properties of a sample which is a subset of a certain population.

In the instance given above, 43% represents the population parameter which describes the percentage number of Democratic voters out of the entire population of voters in the city.

Answer:

The solution to the given inequality is a > 8.

Step-by-step explanation:

For this problem, we have to solve for the inequality.

9a - 24 > 48

add 24 on both sides of the inequality.

9a > 72

Divide 9 on both sides of the inequality.

a > 8

So, your solution would be a > 8.

Answer:

a > 8

Step-by-step explanation:

To solve this inequality, we have to get the variable, a, by itself on one side of the equation

[tex]9a -24 > 48[/tex]

24 is being subtracted from 9a. The inverse of subtraction is addition. Add 24 to both sides of the equation.

[tex]9a-24+24 > 48+24[/tex]

[tex]9a > 48 +24[/tex]

[tex]9a > 72[/tex]

a is being multiplied by 9. The inverse of multiplication is division. Divide both sides of the equation by 9.

[tex]9a/9 > 72/9[/tex]

[tex]a > 72/9[/tex]

[tex]a > 8[/tex]

The solution to this inequality is a > 8

Step-by-step explanation:

1/7 × 100 = 14.28%

1/5 × 100 = 20%

Answer:

Approximately 45,455 total employees.

Step-by-step explanation:

So the company has 13,500 employees in one country. And this represents 29.7% of the company's employees.

In other words:

[tex]\frac{13,500}{\text{Total}}=0.297[/tex]

The left represents the number of employees in one country over the total number.

And the right is the decimal form of 29.7%. Simply move the decimal two places to the left and remove the percent symbol.

So, to solve for the total, multiply both sides by it first. The left side cancels:

[tex]\text{Total}(\frac{13500}{\text{Total}} )=\text{Total}(0.297)\\13500=\text{Total}(0.297)[/tex]

Now, divide both sides by 0.297. The right side cancels:

[tex]\text{Total}=\frac{13500}{0.297}[/tex]

Use a calculator.

[tex]\text{Total}\approx45454.5455[/tex]

So, there is approximately 45,455 total employees.

Answer:

[tex]\Large \boxed{\mathrm{45455 \ employees }}[/tex]

Step-by-step explanation:

29.7% of the company’s employees is 13,500.

Let the number of the company’s employees be x.

[tex]29.7\% \cdot x = 13500[/tex]

[tex]0.297x=13500[/tex]

Dividing both sides by 0.297.

[tex]x= 45454.5454545...[/tex]

There are 45455 employees in total (rounded to nearest whole number).

Answer:  The fraction [tex]\frac{7}{17}[/tex]

This can be written as 7/17 if you are using a computer keyboard.

====================================================

Explanation:

The two negatives next to each other basically cancel each other out to form a positive or a plus sign

We have

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right)[/tex]

turn into

[tex]-\frac{9}{85} +\frac{44}{85}[/tex]

From here, we add the fractions. To do this, we add the numerators and place the sum over the common denominator 85. This is only possible since both denominators are the same number.

[tex]-\frac{9}{85} +\frac{44}{85} = \frac{-9+44}{85} = \frac{35}{85}[/tex]

The last thing to do is to reduce this fraction as much as possible.

We see that 35 and 85 have 5 as a common factor. Divide each number by 5 to get...

Therefore, [tex]\frac{35}{85} = \frac{7}{17}[/tex]

So overall,

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right) = \frac{7}{17}[/tex]

Steps:

If you do the steps correctly, the answer should be 44 ice cream scoops.

(Short way to do this problem/question)

Information given:

1. He uses 1/16 of the bottle of syrup(Every scoop of icecream he eats)

2. The question wants us to find, if he had ate 2 3/4 bottle of chocolate syrup.. how many scoops did he eat.

The steps are::::

1/16 = 16 (scoops of icecream)

Now, if we do 16 times 2 3/4 we would get...

44.

Hence, the answer is 44 scoops of icecream.

[tex]x^3=\boxed{x}\cdot x^2[/tex], and

[tex]\boxed{x}(x^2+2x+1)=x^3+2x^2+x[/tex]

Subtract this from [tex]x^3[/tex] to get a remainder of

[tex]x^3-(x^3+2x^2+x)=-2x^2-x[/tex]

[tex]-2x^2=\boxed{-2}\cdot x^2[/tex], and

[tex]\boxed{-2}(x^2+2x+1)=-2x^2-4x-2[/tex]

Subtract this from the previous remainder to get a new remainder of

[tex](-2x^2-x)-(-2x^2-4x-2)=3x+2[/tex]

[tex]3x[/tex] does not divide [tex]x^2[/tex], so we stop here.

What we've done is to write

[tex]\dfrac{x^3}{x^2+2x+1}=x-\dfrac{2x^2+x}{x^2+2x+1}[/tex]

then

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac{3x+2}{x^2+2x+1}[/tex]

and we stop here because the remainder term [tex](3x+2)[/tex] has a degree less than the degree of the denominator.

Alternatively, we can be a bit tricky and notice that

[tex]x^2+2x+1=(x+1)^2[/tex]

Now,

[tex](x+1)^3=x^3+3x^2+3x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=\dfrac{(x+1)^3-(3x^2+3x+1)}{(x+1)^2}[/tex]

We can divide the first term by [tex](x+1)^2[/tex] easily to get

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3x^2+3x+1}{(x+1)^2}[/tex]

Next,

[tex](x+1)^2=x^2+2x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3((x+1)^2-(2x+1))}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x+1-3+\dfrac{6x+3}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x-2+\dfrac{3x+2}{(x+1)^2}[/tex]

which is the same result as before.

Answer:

Zeroes : 1, 4 and -5.

Potential roots: [tex]\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20[/tex].

Step-by-step explanation:

The given equation is

[tex]x^3-21x=-20[/tex]

It can be written as

[tex]x^3+0x^2-21x+20=0[/tex]

Splitting the middle terms, we get

[tex]x^3-x^2+x^2-x-20x+20=0[/tex]

[tex]x^2(x-1)+x(x-1)-20(x-1)=0[/tex]

[tex](x-1)(x^2+x-20)=0[/tex]

Splitting the middle terms, we get

[tex](x-1)(x^2+5x-4x-20)=0[/tex]

[tex](x-1)(x(x+5)-4(x+5))=0[/tex]

[tex](x-1)(x+5)(x-4)=0[/tex]

Using zero product property, we get

[tex]x-1=0\Rightarrow x=1[/tex]

[tex]x-4=0\Rightarrow x=4[/tex]

[tex]x+5=0\Rightarrow x=-5[/tex]

Therefore, the zeroes of the equation are 1, 4 and -5.

According to rational root theorem, the potential root of the polynomial are

[tex]x=\dfrac{\text{Factor of constant}}{\text{Factor of leading coefficient}}[/tex]

Constant = 20

Factors of constant ±1, ±2, ±4, ±5, ±10, ±20.

Leading coefficient= 1

Factors of leading coefficient ±1.

Therefore, the potential root of the polynomial are [tex]\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20[/tex].
