Answer:
2
Step-by-step explanation:
Because 4x2= 8 than you add it with 8 an the answer is 16
Just multiply 20 x 6 = 140 so your answer is 140. Hope this helps! :)
When we have a right triangle with sides and angles, we use basic trigononemetry. Since we know the vertical leg (height of ramp) and horizontal leg (base length of ramp), we use the inverse tangent function to find the angle.
θ = tan-1(height of ramp / base of ramp) θ = tan-1(2.5 / 6) θ = tan-1(5 / 12)
I believe it is by .28. you take the original number, multiply if by .28 and subtract that answer from the original answer to decrease the amount by 28%.
The z-scores that are the cutoffs are given as follows:
a. z = 1.645.
b. z = -1.96.
c. z = -0.51.
d. z = 0.
e. z = 0.
<h3>What is the z-score formula and what does it represent?</h3>
The z-score of a measure X of a variable that has mean given by and standard deviation represented by is given as follows:
- The z-score measures how many standard deviations the measure X is above(in case the score is positive) or below(in case the score is negative) the mean.
- From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.
For this problem, we have that:
- In item a, the cutoff is the 95th percentile, hence z = 1.645, which has a p-value of 0.95.
- In item b, the cutoff is the 2.5th percentile, hence z = -1.96, which has a p-value of 0.025.
- In item c, the cutoff is the 30.5th percentile, hence z = -0.51, which has a p-value of 0.305.
- In item d, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.
- In item e, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.
