Answer:
22 dollars
Step-by-step explanation:
38 - 16 = 22
if they cost 38 subtract the amount you borrowed(16) and you get what you started with(22)
Answer:
10x - 15
Step-by-step explanation:
let Emily's be x hrs
Abbey = 3x-5 hrs
Nathan = 2 * Abbey's time= 2(3x-5)
= 6x-10 hrs
Expression= x + 3x-5 + 6x-10 = 10x - 15 hrs
Therefore, 10x - 15 is the EXPRESSION THAT DENOTES THE TOTAL NUMBER OF HOURS SPENT FOR DOING HOMEWORK COLLECTIVELY.
<span>So...
We distribute so that...
7 * 2 = 14
7 * i = 7i
then
-3i * 2 = -6i
-3i * -i = 3i?
</span><span>then combine like terms...
7i - 6i + 3i = 4i
so 14 + 4i?</span>
Answer:
$53.83
Step-by-step explanation:
The question is <em>"What is the expected value for the insurance company?"</em>
<em />
The expected value is the sum of the product of each possibility and its probability.
Thus, we have:
The probability of living is 0.9989 and its value is 153
THe probability of dying is (1-0.9989=0.0011) and its value is -90,000
Now, the expected value is:
E(x) = (0.9989)(153) + (0.0011)(-90,000) = $53.83
Answer: The correct option is (D) 
Step-by-step explanation: We are given to find the domain of the following function:
The domain of a function y = f(x) is the set of all possible x-values which will make the function defined or will output real y-values.
That is, for the function (i), the domain will be given by all those values of x for which 
is real.
Now, the values of y will be real only if the expression under square root is greater than or equal to 0.
Therefore, the domain of function (i) is
Thus, the domain of the given function is
Option (D) is CORRECT.
