Which of the following is not a rational number?


Help please

Answer:

Quadrant IV

Step-by-step explanation:

Given

[tex]\theta = -405^\circ[/tex]

Required

The quadrant of the terminal side

To do this, we simply rotate the given angle in a clockwise direction.

A complete rotation is [tex]-360^\circ[/tex]

So, we have:

[tex]\theta = -405^\circ[/tex]

[tex]\theta = -360^\circ -45^\circ[/tex]

Remove the complete rotation

[tex]\theta = -45^\circ[/tex]

When [tex]45^\circ[/tex] is rotated in the clockwise direction, it stops at the 4th quadrant.

Hence, the terminal side falls in the quadrant IV

756=22/7×6^2h

756=22/7×36h

756=113.142h

h=6.7cm

Using translation concepts, the graph that shows the function g(x) = 3|x| is graph B.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Function g(x) = 3|x| is a vertical stretch of 3 units of function f(x) = |x|, that is, they keep the same vertex at (0,0), just graph g is stretched, passing at (1,3) instead of (1,1) for example, hence graph B is correct.

Answer:

1). The correct answer is  letter A)  

6). The correct answer is letetr D)

Step-by-step explanation:

Let be the equation of a sin function:

[tex]sin(x)=Asin(B(x+C))+D[/tex]

Where:

We can see from the image of the problem (6):

The amplitude is: A = 3 units

The vertical shift is: D = 6 units    

The phase shift is:  C = π

The period is : P = 4π = 2π/B then B = 1/2

Therefore the correct answer is letetr D)

[tex]sin(x)=3sin(0.5(x+\pi))+6[/tex]

In the problem (1) we have:

The amplitude is: A = -2 units

The vertical shift is: D = 6 units    

The phase shift is:  C = π/4

The value of B = 1

Then the correct answer is  letter A)

Answer:

(x - 3)² + (y + 2)² = 16

Step-by-step explanation:

Complete question is;

About 130,000 high school students took the AP Statistics exam in 2010. The free-response section of the exam consisted of five open-ended problems and an investigative task. Each free-response question is scored on a 0 to 4 scale (with 4 being the best). For one of the problems, a random sample of 30 student papers yielded the scores that are graphed in the dot plot attached. The mean score for this sample is x¯ = 1.267 and the standard deviation is s = 1.230.

(a) Find and interpret the standard error of the mean.

(b) Construct and interpret a 99% confidence interval to estimate the mean score on this question. Use the four-step process.

Answer:

A) SOE = 0.225

The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225

B) CI = (0.648, 1.886)

The interpretation of this is that;

We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010

Step-by-step explanation:

A) We are given;

sample mean; x¯ = 1.267

Sample standard deviation; s = 1.230

Sample size; n = 30

Formula for standard error of the mean is;

SOE = s/√n

SOE = 1.23/√30

SOE = 0.225

The interpretation of this is that: if a sample size of 30 was taken, the difference between a sample mean score and a population mean score will be an average of 0.225.

B) we have a sample size of n = 30.

Thus;

DF = 30 - 1 = 29

We want to do a 99% Confidence interval.

From the attached t-table, we can see that critical t-value for DF = 29 and CL of 99%, we have t = 2.756

Formula for CI is;

CI = x¯ ± t(s/√n)

CI = 1.267 ± 2.756(1.23/√30)

CI = 1.267 ± 0.619

CI = (0.648,1.886)

The interpretation of this is that;

We are 99% confident that that interval (0.648, 1.886) captures the true mean score of the AP Statistics exam in 2010.

Answer:

The new average is 134/10, or 13.4 years.

Step-by-step explanation:

a + b + c + d + e + f + g + h + i + j

------------------------------------------------ = 13.5    (the original average)

                          10

15 years is 1.5 year older than the 13.5 average and 11 years is 2.5 younger than that.  The net change is 1.5 - 2.5, or -1.  The number of players remains the same:  10.  We subtract 1 from the sum of the player ages and divide the result by 10:

a + b + c + d + e + f + g + h + i + j - 1

---------------------------------------------------    = 13.4    (the new average)

                          10

Note that the sum of the original 10 ages is (10)(13.5), or 135, which becomes 134 after the 15-year-old joined the team and the 11 year old quit.  The new

average is 134/10, or 13.4 years.

Answer:

I dont know sorry :(:(:(:(:(:(:(:(:(

mean is the average and can be calculated by adding the scores and then dividing by the total number of scores.

for this take the total number of childrena and divide by the number of families which should give 3.5.

median is the middle number when the scores are put in order.

an easy way to find it from this data set is to just add the number of families from top down and bottom up and seeing where they meet which should be 3.

mode is the number that occurs the most in a data set.

for this data set it would be where the greatest number for number of families is which is 3 as there is 82 families.
