Answer:
#19: x=3
#20: would be n=4 i think
Step-by-step explanation:
#19- there are 4 x's and 12 +1's so 4 into 12 is 3.
#20- well the answer that i got was 5 but 4 was closer to 5 so yea.
i sure hope this helps!
A deck of 52 hours has 4 nines.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 ) =
= 0.0412 + 0.588 = 0.1
Answer:
The probability is 0.1 ( or 10%).
The change in the price of the stock is $46.67.
<h3>How to calculate the change in price?</h3>
From the information given, the current price will be:
= Annual dividend / Required rate
= 7/0.1
= $70
The market value of the shares will be:
= 7/6%
= 7/0.06
= $116.67
Therefore, the change in the price of the stock will be:
= $116.67 - $70
= $46.67

The resulting composite function (f∘f)(x) is x⁴+2x²+2
When a function is written inside another function, it is known as a composite function
Given the function f(x)=x²+1,
(f∘f)(x) = f(f(x))
f(f(x)) = f(x²+1)
This means we will need to replace x with x²+1 in f(x) as shown:
f(x²+1) = (x²+1)²+1
Expand
f(x²+1) = x⁴+2x²+1+1
f(x²+1) = x⁴+2x²+2
Hence the resulting composite function (f∘f)(x) is x⁴+2x²+2
