Answer:
Standard score z=0.07
Step-by-step explanation:
The z-score, or standard score, represents an equivalent value for X but in the standard normal distribution, where μ=0 and σ=1.
For X=28.3 in a normal distribution with μ=26.3 and σ=28.1, the standard score can be calculated as:
This value is 0.07 standard deviations right to the mean.
In the picture attached, we have located the z-score.
Answer:
The likelihood that a point chosen inside the square will also be inside the circle: 78.54%
Step-by-step explanation:
=> the area of the square is:
=> the area of the circle : π
However, d=x because of the square property
<=> the area of the circle : π
The likelihood that a point chosen inside the square will also be inside the circle:
the area of the circle / the area of the square
= π /
= π *100%
= 0.7854 * 100%
= 78.54%
Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.
Also the cosine ratio is adjacent over hypotenuse.
The tangent ratio does not come close because it doesn't involve the Hypotenuse.
