Remember your PEMDAS! Do your parenthesis first (4-2) and (6-2), then multiply (6-2) by 2, finish off your big parenthesis with addition and subtraction, and finally, multiply by three.
It should go something like this:
3[26 + (2) - (4)2]
3[26 + (2) - 8]
3[28 - 8]

Find the exact value of the following limit: lim x approaches 0 e^6x... check photo above.

Answers

Substituting x = 0 directly gives the indeterminate form 0/0, so you can use l'Hopital's rule (and you'll have to do that twice):

[tex]\displaystyle\lim_{x\to0}\frac{e^{6x}-6x-1}{x^2}=\lim_{x\to0}\frac{6e^{6x}-6}{2x}=\lim_{x\to0}\frac{36e^{6x}}2[/tex]

The limand is continuous everywhere, so you can plug in x = 0 to get 36•1/2 = 18.

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?

Answers

Answer:

Step-by-step explanation:

There are 500 respondents will you be able receive for the money paid.

What is mean by expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.

And, They charge $1,800 + $6 per respondent.

Now,

Let Number of respondents will you be able receive for the money paid is, x

Hence, We can formulate;

⇒ $1800 + $6x = $4800

⇒ 1800 + 6x = 4800

⇒ 6x = 4800 - 1800

⇒ 6x = 3000

⇒ x = 500

Thus, There are 500 respondents will you be able receive for the money paid.

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used

Answers

Question:

For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.

Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answer:

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

Step-by-step explanation:

Given

[tex]Water = 1L[/tex]

[tex]Sucrose = 150mL[/tex]

[tex]Saline= 600mL[/tex]

Required

Express as a ratio to the simplest form

First convert the volume of water to mL

[tex]Water = 1L[/tex]

[tex]Water = 1 * 1000mL[/tex]

[tex]Water = 1000mL[/tex]

Express as ratio:

[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]

[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]

Divide through by 10

[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]

Divide through by 5

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

The ratio can not be further simplified

Select ALL of the values that are solution to the inequality below.

f. x=2

g. x=3

Step-by-step explanation:

[tex] \frac{7x + 6}{2} \leqslant 3x + 2 \\ 7x + 6 \leqslant 2(3x + 2) \\ 7x + 6 \leqslant 6x + 4 \\7x - 6x \leqslant 4 - 6 \\ \boxed {x \leqslant - 2}[/tex]

#1 Line

Slope = 4.000/2.000 = 2.000

x-intercept = 1/-2 = -0.50000

y-intercept = 1/1 = 1.00000

#2 Slope = 2.000/2.000 = 1.000

x-intercept = 2/-1 = -2.00000

y-intercept = 2/1 = 2.00000

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(2*x+1)=0

Equation of a Straight Line

1.1 Solve y-2x-1 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-2x-1 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000

y-intercept = 1/1 = 1.00000

Calculate the X-Intercept :

When y = 0 the value of x is 1/-2 Our line therefore "cuts" the x axis at x=-0.50000

x-intercept = 1/-2 = -0.50000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.000 - 1.000 = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 4.000/2.000 = 2.000

Geometric figure: Straight Line

Slope = 4.000/2.000 = 2.000

x-intercept = 1/-2 = -0.50000

y-intercept = 1/1 = 1.00000

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(x+2)=0

So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 4.000 - 2.000 = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 2.000/2.000 = 1.000

introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (a) Identify the population of interest and the sample in this study. (b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.

Answers

Answer:

The solution to this question can be defined as follows:

Step-by-step explanation:

In choice a:

Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.

In choice b:

These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg
