Please help. I'm not really good at these kind of problems. Working alone, Dan can do a certain job in three hours and Stan can do the same job in two hours. At these rates, how long would it take Dan and Stan to do this job working together?

Answers

Answer 1

Answer: The answer is it would take Dan and Stan 1 hour if they work together, because 3-2=1, so make those hours and you have 1 hour.

The real-world scenario is given as: A yacht traveling 20 miles due east off a harbor is located 50 miles due north from the yacht

Recall:

Pythagorean Theorem applies to a right triangle where and c is the hypotenuse.

If we know the two of the three side lengths of a right triangle, we can find the other third length.

An example of a scenario where the Pythagorean Theorem can be applied to solve a real-world problem can be sketch in a diagram

Answers

Answer:

(2, -9)

Step-by-step explanation:

2 - (-9) > 8      First, substitute the values for x and y.

2 + 9 > 8        

11 > 8              The inequality is true, so (2, -9) is the correct pair.

Answer:

Answer is C

Step-by-step explanation:

basically you substitute (X,Y) in X-Y >0. so X-Y should be greater than 0. also, make sure you use the signs properly.

so in C. 3--10 > 0 so negative sigs cancel each other out so its 3+10 so 13> 0

The mean vitamin C level for 20 dogs was 7.6 milligrams per liter, with a standard deviation of 2.1 milligrams per liter.

One dog’s vitamin C level was not in the normal range. It was 0.9 milligrams per liter, which is a very low level of vitamin C.

If the value 0.9 is eliminated from the data set, does the mean increase or decrease?

Your answer:
I will give you 5.0 and a thanks and maybe brainliest

Answers

Answer:  The mean increases.

Step-by-step explanation:

The value of 0.9 mg/L is very low compared to a means of 7.6 mg/L with a standard deviation of 2.1 mg/L.  It seems as though it is an outlier that is suffiently different from the others, and probably should be dropped from the data set.  That would do 2 things:  1) the stabdard deviation will likely decrease, indicating a more confident data set, and 2) the mean vitamin C level will increase.

ln(5)
5ln(x)
ln(x)

Answers

Answer:

5x

Step-by-step explanation:

The natural log of 5x is the exponent to give e to get 5x as a result.  You are simply applying the definition of logarithm

The expression [tex]e^{ln(5x)[/tex] evaluates to 5x after simplification.

Option: A is correct.

Here, we have,

The expression [tex]e^{ln(5x)[/tex] involves two important mathematical properties:

[tex]e^{ln(x)} = x[/tex]:

This is a fundamental property of the natural logarithm and the base of the natural exponential function, e.

When the natural logarithm (ln) and the natural exponential function [tex](e^x)[/tex] are composed, they "cancel out," and the result is the argument inside the ln function (x).

[tex]e^0 = 1[/tex]:

The natural exponential function raised to the power of 0 is equal to 1.

Now, let's simplify the expression step by step:

[tex]e^{ln(5x)[/tex]

Using property 1,[tex]e^{ln(5x)[/tex] simplifies to:

5x

Therefore, the correct option is "5x."

The expression [tex]e^{ln(5x)[/tex] evaluates to 5x after simplification.

Option: A is correct.

Given the sequence 3, 1,-1, -3, ... use the arithmetic sequence formula to write an equation.

Answer:

a₃₂ = - 59

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = a₂ - a₁ = 1 - 3 = - 2 , then

[tex]a_{n}[/tex] = 3 - 2(n - 1) = 3 - 2n + 2 = - 2n + 5

Write an
equation for the circle with centre (0,0), if (12,5) lies on its circumference

Answers

Answer:

x² + y² = 169

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Given (12, 5 ) lies on the circumference , then the point will satisfy the equation.

Substitute (12, 5 ) into the equation

12² + 5² = r²

144 + 25 = r²

169 = r²

Then equation of circle is

x² + y² = 169

What's Test Statistic?

A test statistic is a figure attained from a statistical analysis. It explains how far your observed data is from the null thesis, which states that there's no correlation between the variables or distinction between the sample groups.

Test statistics are statistics that are produced from samples to determine whether or not to accept the null thesis.

A sample is data that represents a portion of the population. In other words, it's a gauged - down interpretation of a larger group.

The croaker conducted a thesis test in order to corroborate the information that has been handed in the question. And he calculated the test statistic, or arbitrary data from the sample taken from the population data, for the thesis test.

tax rate, and both families made $16,000 in taxable purchases last year. If the If

Answers

Answer:

Yes, the sales tax in their city is an example of regressive tax

Step-by-step explanation:

Firstly, we need to understand what is meant by the term regressive tax.

What is meant by a regressive tax system is a system of taxation in which there is a decrease in tax rate as there is an increase in amount subjected to tax.

Now, the key to knowing if what we have in the question is a regressive taxation is by calculating the percentage of the tax that was paid.

For the Roosevelt’s , the percentage of tax paid would be 16,000/91,000 * 100% = 17.6%

For the Jasper’s, the percentage of tax paid would be 16,000/37,000 * 100% = 43.24%

We can see that at a lower amount subjected to tax, the Jasper’s paid more and thus we can conclude irrevocably that sales tax in their city is an example of a regressive tax
