The Sine Function

According to the National Weather Service, the average monthly high temperature in the Dallas/Fort Worth, Texas area from the years of 2006-2008 is given by the following table:

Plot the data on a scatter plot. Produce a sine regression model for the data. Round the values for a a, b, c, and d to the nearest 0.0001. Using the sine regression model predict what the temperature would be given y(30). Analyze your prediction and explain why your prediction may or may not be accurate. If it might not be accurate, explain what might make the information more accurate.

a. Accurate, nothing would help it be more accurate.
b. May not be accurate, weather is charging all the time; Information from various states would help make the information more accurate.
c. Accurate, it is easily predictable.
d. May not be accurate, information was taken over 2 year period; More information
from previous years would help the prediction be more accurate.

A to E goes from 0 to 1 so I assume 0 means zero possibility (impossible) then to continue unlikely. now even chance at C (in the middle which makes sense) then likely and then 1 is certain

Choose the correct order when finding the space between the cylinder and cone. I find the difference of the volumes Il find the volume of the cone III. find the volume of the cylinder​

Answers

Answer:

D. III, II, then I

Step-by-step explanation:

To find the space between the cylinder and the cone, the first thing to do is: find the volume of the cylinder => next is to find the volume of the cone => then look for the difference in volume between the cylinder and the cone which will give us the space between the cylinder and the cone.

The correct order would be:

(2/3)(9)=6

Lyle wrote 6 pages on Friday.

9-6=3

this makes sense, because since he wrote 2/3 of the report on Friday, there will be 1/3 of the report to do on Saturday. (1/3)(9)=3

Answers

Answer:

its 28

Step-by-step explanation:

C is the longest side which is 35 ye and b is 21 yd. Then you would subtract 21^2 from 35^2 and you would get 784. Then find the square root of 784 and you would get 28 as the answer! Good luck and have a great day or night!

Answer:

28 yards

Step-by-step explanation:

We can use pythagorean theorem to solve this problem; pythagorean theorem is denoted by the formula a^2 + b^2 = c^2. We already have b, as 21 yd and c, as the hypotenuse is 35 yd. We can plug these values into the formula:

a^2 + 21^2 = 35^2

a^2 + 441 = 1225

a^2 = 784

a = 28 yards

Bet u can’t solve this

Answers

Answer:

Step-by-step explanation:

Assuming you're solving for p:

[tex]m=2^{-1} *2^p(2^p-1)[/tex]

Let [tex]y=2^p[/tex]

Now we can re-write the equation with [tex]y[/tex] instead of [tex]2^p[/tex].

[tex]m=\frac{1}{2} y(y-1)[/tex]

[tex]2m=y^2-y[/tex]

[tex]y^2-y-2m=0[/tex]

Use the quadratic formula to get:

[tex]y = \frac{1+\sqrt{1+8m} }{2}[/tex]

or

[tex]y = \frac{1-\sqrt{1+8m} }{2}[/tex]

Therefore, using natural log and log rules:

[tex]2^p = \frac{1+\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2})[/tex],[tex]pln(2) = ln(\frac{1+\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}[/tex]

or

[tex]2^p = \frac{1-\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]pln(2) = ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}[/tex]

If I haven't made any mistakes this should be correct!

Test to see whether the mean tree-planting time differs from two hours.
State the null and alternative hypothesis

Answers

Answer:

H0 : μ = 2

H1 : μ > 2

We fail to reject the null and conclude that no significant evidence exists to support that mean tree-planting time differs from two hours.

Step-by-step explanation:

Given :

X = 23.71,17.79,29.87,18.78,28.76

Sample mean, xbar = Σx / n = 22/10 = 2.2

Standard deviation, s = 0.516 (calculator)

H0 : μ = 2

H1 : μ > 2

Test statistic :

(xbar - μ) ÷ (s/sqrt(n))

n = 10

Test statistic :

(2.2 - 2) ÷ (0.516/sqrt(10))

0.2 / 0.1631735

Test statistic = 1.23

Using the Pvalue from Tscore calculator, df = n - 1 = 10 - 1 = 9

Pvalue(1.23, 9) = 0.1249

Since, Pvalue > α ; We fail to reject the null and conclude that no significant evidence exists to support that mean tree-planting time differs from two hours.
