Answer:

Option a is correct.  

The rotation for the transformation ​​ to ​ △A'B'C' is , rotation of 90 degree.

Explanation:

In  △ABC

The coordinate of point A = (1,1) , B = (3,1) and C = (1,4).

Rotate triangle ABC 90 degree's around the origin;

The rule for this transformation is:-  (x,y) to (-y ,x)

A(1,1) to A' (-1,1) ,

B(3,1)  to B'(-1 , 3) and

C(1,4)  to C' (-4,1)

therefore, rotation of 90 degree counter clockwise rotation around the origin results in the transformation of ​ △ABC ​​ to ​ △A'B'C'

G a frequency distribution has a mean of 200 and a standard deviation of 20. the class limits for one class are 220 up to 240. b
cestrela7 [59]

A suitable probability calculator will show that probability to be .135905122.


_____

Your class extends from 1 standard deviation above the mean to 2 standard deviations above the mean. The empirical rule puts that probability at ...

... (1/2)(95% - 68%) ≈ 13.5%


The empirical rule tells you 68% of observations lie within 1 standard deviation of the mean, and 95% lie within 2 standard deviations. Then the number that lie between 1 and 2 standard deviations from the mean will be the difference of these values. You want the values in the region above the mean only, so you only want half the difference just described.

Given a normal distribution with mu equals 100μ=100 and sigma equals 10 commaσ=10, complete parts​ (a) through​ (d). loading...
m_a_m_a [10]

I believe the parts are:

A. What is the probability that Upper X greater than 95X>95​?

B. What is the probability that Upper X less than 75X<75?

C.What is the probability that Upper X less than 85X<85 and Upper X greater than 125X>125?

D. 95​% of the values are between what two​ X-values (symmetrically distributed around the​ mean)?

 

<u>Solution:</u>

We use the equation for z score:

z = (X – μ) / σ

Then use the standard normal probability tables to locate for the value of P at indicated z score value.

 

A. Z = (95 – 100) / 10 = - 0.5

Using the tables, the probability at z = -0.5 using right tailed test is:

P = 0.6915

 

 

B. Z = (75 – 100) / 10 = - 2.5

Using the tables, the probability at z = -2.5 using left tailed test is:

P = 0.0062

 

 

C. Z = (85 – 100) / 10 = - 1.5

Using the tables, the probability at z = -2.5 using left tailed test is:

P = 0.0668

 

Z = (125 – 100) / 10 = 2.5

Using the tables, the probability at z = 2.5 using right tailed test is:

P = 0.0062

 

So the probability that 85<X and X>125 is:

P(total) = 0.0668 + 0.0062

P(total) = 0.073

 

 

D. P(left) = 0.025, Z = -1.96

P(right) = 0.975, Z = 1.96

 

The X’s are calculated using the formula:

X = σz + μ

 

At Z = -1.96

X = 10 (-1.96) + 100 = 80.4

 

At Z = 1.96

X = 10 (1.96) + 100 = 119.6

 

<span>So 95% of the values are between 80.4 and 119.6 (80.4< X <119.6).</span>
