Question 19

Mathematics
1 answer:

Answer: 10√17

Step-by-step explanation:

The movement of the boat takes the shape of a trapezium as shown in the attached photo.

The distance of the boat from its starting point is represented by x kilometers.

To determine the distance, x, we would apply Pythagoras theorem on the right angle triangle ABC formed. It is expressed as

Hypotenuse² = opposite side² + adjacent side². It becomes

x² = 40² + 10² = 1600 + 100

x² = 1700

x = √1700 = √100 × √17

x = 10√17

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ
katrin2010 [14]

Answer:

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will <u>increase</u>.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will:

We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.

When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.

When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.

Therefore, the correct word for our given statement is increase.

How do I find the horizontal asymptote of h(x)=x+6/x^2-64 ?
SashulF [63]

I assume the equation described is:

( x + 6 ) / ( x^2 - 64 )

You can compare the degree of the numerator and denominator in a function that takes the form of this type of rational equation.

Here are the three rules

#1 (Correct Answer): When the degree of the numerator is smaller then the denominator the horizontal asymptote is y = 0

#2 If the degree of the numerator and denominator is the same, then you take the leading coefficient of the numerator (n) and denominator (d) to create the answer y = n / d in this equations case it would be 1 / 1 since variables technically have an invisible 1 in front of them since anything multiplied by 1 is its self, 1x = x

#3 When the degree of the numerator is greater then the degree of the denominator then this means that it does not have a horizontal asymptote.

Again the final answer is that the horizontal asymptote is y = 0
