Answer:
Probability the first is a communications major and the second is a business major = 0.03
Step-by-step explanation:
let the total number of students be 100
Event A= Business Majors = 15%
Event B = Communication Majors = 20%
P(A) = ⇒ P(A) = 0.15
P(B) = ⇒ P(B) = 0.2
P( A and B) = P(A) × P(B)
= 0.15 × 0.2
= 0.03
Answer:
20 times
Step-by-step explanation:
2000 x 10% = 200
200x = 4000
x= 20
20 times
When dividing fractions you keep the first fraction, change the division sign to multiplication, and flip the second fraction. (Keep Change Flip) For mixed numbers, make it a fraction by multiplying the whole number times the denominator, adding that to the numerator, and put that sum over the same denominator. Then do Keep Change Flip

The statement, "Because the two distributions displayed below have similar shapes, they have the same standard deviation." is false. This is false because distributions having the same mean and standard deviation can have very different shape of distribution. </span>
(-4)+10=6 if you add (-4) to 10
it is like subtracting 4 from 10
witch equals six
