Answer:
Question 1:
Here total number of students GPA is given = 50
Number of people who have GPA more than 3.69 = 5
Therefore,
Pr(That a student has GPA more than 3.69) = 5/50 = 0.1
Here X ~ NORMAL (3.12, 0.4)
so Pr(X > 3.69) = Pr(X > 3.69 ; 3.12 ; 0.4)
Z = (3.69 - 3.12)/ 0.4 = 1.425
Pr(X > 3.69) = Pr(X > 3.69 ; 3.12 ; 0.4) = 1 - Pr(Z < 1.425) = 1 - 0.9229 = 0.0771
Question 2
Here GPA would be above 95.54th percentile
so as per Z table relative to that percentile is = 1.70
so Z = (X - 3.12)/ 0.4 = 1.70
X = 3.12 + 0.4 * 1.70 = 3.80
so any person with GPA above or equal to 3.80 is eligible for that.
Answer:
Step-by-step explanation:
We have, 120% × x = 36
or,
120
100
× x = 36
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 36 ×
100
120
x = 30
The answer for 1113 divided by 14 is 79.5
To find this question's answer, we need to know that sum of the exterior angles of any given polygon is 360°. This is default and non-changeable.
Now we know that the sum of all exterior angles is 360°, the question says that one angle is equal to 36°.
When we divide them we get:

So, we found that there are 10 exterior angles.
Answer:240 m
Step-by-step explanation:
Given Balloon is going towards positive x direction with a speed of 10 m/s
and balloonist throw the ball with -2 m/s with respect to himself
thus absolute ball velocity is 12 m/s
As there is no horizontal force in x direction thus distance covered by ball in 20 sec is
R=
=240 m
