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.
Answer:
9.5 inches
Step-by-step explanation:
The radius is 1/2 of the diameter
19/2 = 9.5 inches
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!
Answer:
1/2
Step-by-step explanation:
4 fruit and 2 of them are banana so 2/4
banana go on top and total number of fruit go on bottom
to simplify divide numerator and denominator by 2
2/2 1
------ = ---------
4/2 2
We know that to find the area of the entire circle, we are going to use the equation:

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:


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
by 5 to find the area of each section:

Each section has an area of
or, using 3.14 for pi,
.
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:

Therefore, the answer is C) 45.2
