Probability and Statistics Normal Distribution Test For questions, 1-5 assume that a normal distribution has a mean of 85 and
a standard deviation of 5. Label the graph to accurately reflect this, and
then find the percentages of the data that falls within the specified area
asked by the questions.
1. Between the values of 80 and 90.
2. Between the values of 85 and 95
3. Above 90
4. Below 85
5. Below 95 and above 85
For the following problems, find the area under the standard normal curve.
6. To the left of z = -1.08
7. To the right of z = 1.35
8. Between z= -2.25 and 2 = 2.25
9. To the left of z = -1.45 and to the right of z = 1.96

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
