Answer:
Step-by-step explanation:
Let <em>P(A) </em>be the probability that goggle of type A is manufactured
<em>P(B) </em>be the probability that goggle of type B is manufactured
<em>P(E)</em> be the probability that a goggle is returned within 10 days of its purchase.
According to the question,
<em>P(A)</em> = 30%
<em>P(B)</em> = 70%
<em>P(E/A)</em> is the probability that a goggle is returned within 10 days of its purchase given that it was of type A.
P(E/B) is the probability that a goggle is returned within 10 days of its purchase given that it was of type B.
will be the probability that a goggle is of type A and is returned within 10 days of its purchase.
will be the probability that a goggle is of type B and is returned within 10 days of its purchase.
If a goggle is returned within 10 days of its purchase, probability that it was of type B:
So, the required probability is

C) 5 3√2
Step-by-step explanation:
Put in order from smallest to largest
–9, –4, –1, 2, 3, 5, 7
Minimum = –9<span>
Maximum = 7
</span>Range = 7 - (-9) = 7 + 9 = 16
Range = the difference between the maximum and minimum data values

Answer:
Cost of the coat = $54
Step-by-step explanation:
Given:
She saved = $ 9
To Find:
Cost of the coat = ?
Solution:
Let the price of coat be x
She saved $9
and according to given condition it is 1/6 of the total money she needs for buying coat
by this we have
Multiplying both sides by 6
it becomes
x = 9*6
x = $54
As x is the amount she needs
so
Cost of the coat = $54
