To determine the probability that both people chosen are females, we will use the rule of multiplication.
Let event A = the event that the first person chosen is female; and let B = the event that the second person is female.
To start, it is given that there are 10 students, 5 of them are females. Therefore, P(A) = 5/10
After the first selection, there are 9 students, 4 of them are females. Therefore, P(A|B) = 4/9
Based on the rule of multiplication:
P(A∩B) = P(A) * P(A|B)
P(A∩B) = (5/10) (4/9)
P(A∩B) = 20/90
P(A∩B) = 2/9
The probability that both people chosen are females is 2/9.
Answer:
Step-by-step explanation:
We know the property of derivative: 
Given function : 
Differentiate both sides with respect to x , we get

[By Chain rule]

[Since
, where a is scalar and
]

Hence, the derivative of the given function is
.
Answer:
Explanation:
15 goes into 60, 4 times (1 fourth is equal to 25%).
15 goes into 75, 5 times (1 fifth is equal to 20%)
So 75 is one fifth more because it has a value of 15 more, and 60 is 1 fourth less than 75 because its value is more minuscule and less is more.
If you don't understand this was quite the challenge to explain.
Let, the price of jacket before tax = x
it would be: x*105/100 = 118.65
x = 11865/105
x = $113
To find the slope, we must put the equation in y = mx + b form, and m represents ur slope.
7x - 2y = 4....subtract 7x from both sides
-2y = -7x + 4 ...now divide both sides by -2
y = (-7/-2)x + (4/-2)
y = 7/2x - 2....now we have it in y = mx + b form, and since m is ur slope, ur slope in this equation is 7/2.
