lianna [129]

I've attached the complete question.

Answer:

Only participant 1 is not cheating while the rest are cheating.

Because only participant 1 has a z-score that falls within the 95% confidence interval.

Step-by-step explanation:

We are given;

Mean; μ = 3.3

Standard deviation; s = 1

Participant 1: X = 4

Participant 2: X = 6

Participant 3: X = 7

Participant 4: X = 0

Z - score for participant 1:

z = (x - μ)/s

z = (4 - 3.3)/1

z = 0.7

Z-score for participant 2;

z = (6 - 3.3)/1

z = 2.7

Z-score for participant 3;

z = (7 - 3.3)/1

z = 3.7

Z-score for participant 4;

z = (0 - 3.3)/1

z = -3.3

Now from tables, the z-score value for confidence interval of 95% is between -1.96 and 1.96

Now, from all the participants z-score only participant 1 has a z-score that falls within the 95% confidence interval.

Thus, only participant 1 is not cheating while the rest are cheating.

The inverse of the linear function y=1/2x+3
GarryVolchara [31]
The inverse would be y=-1/2x+3 because the inverse is the negative of the function.  to make the function negative make the slope negative and keep the y-intercept.

I hope I've helped!

Find the area of the blue sector(s). The diameter of the wheel is 12
Ber [7]

We know that to find the area of the entire circle, we are going to use the equation:


A=\pi r^{2}


And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.


Now we can use this radius in the equation:


A=\pi (6)^{2}


A=36\pi


Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide 36 \pi by 5 to find the area of each section:


\frac{36 \pi}{5} =7.2 \pi


Each section has an area of 7.2\pi units^{2} or, using 3.14 for pi, 7.2*3.14=22.61units^{2}.


Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:


22.61*2=45.22units^{2}


Therefore, the answer is C) 45.2 units^{2}.
