If x=3+bi, then
You know that 
then
Two possible complex numbers satisfy these conditions:
As you can see the possible value of b is 2.
Answer: correct choice is A.
One temperature colder that -7.2 F would be -9 F.
-9 < -7.2
The -9 would be 1.8 units to the left of -7.2 on the number line.
Answer: B. t = 9.6tan(29°)
Step-by-step explanation:
<u>Based on the fact:</u>
<u>Set x = 29 and solve:</u>
A quarter is either:
A. 1/4
B. 25 cents
if it is 1/4 then
9 quartrers is 9 times 1/4=9/4=2 and 1/4
if it is 25 cents then
0.25 dollars times 9=$2.25
Answer:
-$500
Step-by-step explanation:
The expected value of a payment from the policy is ...
$500,000 × 0.002 = $1000
Since the business pays $1500 for the policy, the expected value to the business is ...
$1000 - 1500 = -$500 . . . per year
_____
Of course, the expected value to the insurance company is $500 per year.
_____
We have computed on the basis of 1 claim per year. If we consider the possibility of multiple independent claims, then the expected payment from the insurance goes up by a factor of 1/(1 -0.002) ≈ 1.002004008016.... This has the effect of increasing the expected value by $2.00 per year to -$498.
