The first step to solving the expression:
[tex]3.7x\text{ - 15.9 = 2.79}[/tex]We need to transfer that term that doesn't have "x" from the left side to the right side. To do this we need to invert its signal as shown below:
[tex]3.7x=2.79+15.9[/tex]The second step is to sum the terms with similar letters or no letters at all.
[tex]3.7x\text{ = }18.69[/tex]The third step is to isolate the "x" variable by switching the constant that is multiplying it from the left side to the right side. To do that the constant needs to divide on the right.
[tex]\begin{gathered} x\text{ = }\frac{18.69}{3.7} \\ x\text{ = }5\text{.}05 \end{gathered}[/tex]At a park, the jogging trail is a circle with a radius of 200 meters. How far is it around the trail? Use 3.14 for π
Given
At a park, the jogging trail is a circle with a radius of 200 meters.
To find: How far is it around the trail? (Use 3.14 for π).
Explanation:
It is given that,
The radius of the circular trial is 200meters.
Then, the length path around the trial is,
[tex]\begin{gathered} Circumference\text{ }of\text{ }circle=2\pi r \\ =2\times3.14\times200 \\ =4\times314 \\ =1256m \end{gathered}[/tex]Hence, the length of the path around the trial is 1256m.

O {(14, 15). (5. 15). (3. 15). (11, 15). (5, 15)}
Answer: the last one
Step-by-step explanation:
the easiest way to do this is the vertical line test. Graph the relation separately and then roll a pencil over each one. If the pencil touches two points at the same time, then it is not a function. Or you can look at the x inputs and if any are the same, it’s not a function.
Convert 1.6 x 10-2 to standard notation.

The first one is 10 pages long, while the second one is 20 pages long. The second one has 40 pages, which is twice as much as the first. The eighth book has 1280 many pages.
Given that,
On his desk, Brandon has a stack of books.
The first one is 10 pages long, while the second one is 20 pages long. The second one has 40 pages, which is twice as much as the first.
For eight novels, this pattern is maintained.
We have to find the eighth book has how many pages.
We have to multiply 2
40 times 2=80
80 times 2 =160
160 times 2=320
320 times 2=640

A sequence could be a list of numbers that have been arranged sequentially whereas series can be exceedingly generalized as the sum of all the terms in a sequence be that as it may, there must be a clear relationship between all the terms of the sequence. An infinite arrangement is given by all the terms of an unbounded grouping, included together and the sum of the series is just adding the n number of terms

Sabreena is playing a card game, and the odds of her winning after drawing the next card are 5:7.
What is the probability of her not winning?
Enter your answer as a decimal rounded to the nearest thousandth, like this: 0.423
Giving that her probability of winning is 5:7, Her Probability of not winning is; 0.286
What is the Probability of not winning?
According to binomial probability distribution, the probability is usually given by the formula;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
where;
p is probability of success
n = number of trials, or the sample size
x = the number of "successes" in the probability
Now, we are told that the probability of winning in the next card is 5:7. Writing this in fraction form is 5/7.
Now, we know that percentage of winning + percentage of losing equals to 1. Thus;
Percentage of not winning + 5/7 = 1
Percentage of not winning = 1 - 5/7
Percentage of not winning = 2/7
In percentage form, this gives us;
2/7 * 100% = 28.57% = 0.286

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between and . Assume that a confidence interval estimate of the population mean annual starting salary is desired. a. What is the planning value for the population standard deviation? b. How large a sample should be taken if the desired margin of error is ? Round your answers to next whole number. ? ? c. Would you recommend trying to obtain the margin of error? Explain.
Because of the very huge sample size, we do not advise attempting to acquire the $100 margin of error.
The annual starting salaries for college graduates with degrees are between $30,000 and $45,000.
The confidence interval is 95%.
The planning value of the population standard deviation is expressed as:
= ( 45000 - 30000 ) / 4
= 15000/4
= 3750
And, 95% confidence interval a is 0.05.
Using the standard normal table,
Z(0.025) = 1.96
(a) For error E = $500,
n = ( Z × S/E )²
n = ( 1.96 × 3750/500)²
n = 216.09 = 217
(b) For error E = $200,
n = ( Z × S/E )²
n = ( 1.96 × 3750/200)²
n = 1351
(c) For error E = $100
n = ( Z × S/E )²
n = ( 1.96 × 3750/100)²
n = 5403
Therefore, Due to the sample size being too huge, we do not advise attempting to achieve the $100 margin of error.

I am having trouble with this equation & how to correctly use the [ & ) when it comes to writing in interval notation.
We need to solve the inequality:
[tex]4\left(2-x\right)>\left(5x-7\right)-\left(x-10\right)[/tex]In order to do so, we can expand the expressions on each side, then apply the same operations on both sides of the inequality until we isolate the variable x and find the solution.
By expanding the expression, we obtain:
[tex]\begin{gathered} 4(2)+4(-x)>5x-7-x-(-10) \\ \\ 8-4x>5x-x-7+10 \\ \\ 8-4x\gt4x+3 \end{gathered}[/tex]Now, adding 4x to both sides, we obtain:
[tex]\begin{gathered} 8-4x+4x>4x+3+4x \\ \\ 8>8x+3 \end{gathered}[/tex]Subtracting 3 from both sides, we obtain:
[tex]\begin{gathered} 8-3>8x+3-3 \\ \\ 5>8x \end{gathered}[/tex]Then, dividing both sides by 8, we obtain:
[tex]\begin{gathered} \frac{5}{8}>\frac{8x}{8} \\ \\ \frac{5}{8}>x \\ \\ x<\frac{5}{8} \end{gathered}[/tex]Notice that x must be less than 5/8. Thus, 5/8 does not belong to the solution set.

A tablet and a digital camcorder are both on sale for 30% off. The regular price of the tablet is $185. The regular price of the camcorder is $140. Part A Find the sale price of the tablet. Explain. Part B What is the sale price of the camcorder?
Part A
We need to find the sale price of the tablet, i.e., after a discount of 30% was applied.
When we apply a discount rate d to a price P, the sale price S is given by:
[tex]S=(1-d)\cdot P[/tex]In this problem, the original price of the tablet, in dollars, is:
[tex]P=185[/tex]And the discount rate is:
[tex]d=30\%=\frac{30}{100}=0.3[/tex]Then, the sale price is given by:
[tex]S=(1-0.3)\cdot185=0.7\cdot185=129.5[/tex]Therefore, the sale price of the tablet is $129.50.
Part B
Now, we can use the same formula to find the sale price of the camcorder, using:
[tex]\begin{gathered} P=140 \\ d=0.3 \end{gathered}[/tex]We obtain:
[tex]S=(1-0.3)\cdot140=0.7\cdot140=98[/tex]Therefore, the sale price of the camcorder is $98.

Is Susan correct? If so, write yes. If she is wrong, rewrite the statement to make it true.
You could change more to less, change the planets-do whatever you need to do to
make a TRUE statement for Susan.
A TRUE statement for Susan is: "Venus is less than twice as far from the Sun as Mercury is."
Given:
The distance of each planet from the Sun,
Mercury - 51,000,000
Venus - 10000000
Earth - 150000000
Susan said, "Venus is more than twice as far from the sun as Mercury is."
51,000,000 × 2 = 102,000,000
When we calculate twice the distance of Mercury from the Sun it is much greater than the actual distance of Venus from the Sun.
(102,000,000 > 10000000)
Hence, the statement is incorrect and so is Susan.
The correct statement should be:
"Venus is less than twice as far from the sun as Mercury is."
