Answer:
3 * 8^(x/2)
Step-by-step explanation:
The third answer choice is the correct one.
Here's how:
3squareroot of 8^x = 3√(8^x) = 3*(8^x)^(1/2) = 3 * 8^(x/2)
Answer:
Probability of having at least 4 Girls
= 0.6875
Step-by-step explanation:
Probability of having at least 4 Girls is 1-probability of having exactly 3 girls
Total number of children= 5 = N
Probability of having a girl p = 0.5
Probability of not having a girl q= 0.5
X= 3
Probability of at least 4 girls is given by
Probability= NCX(p)^x(q)^(N-x)
Probability = 5C3(0.5)^3(0.5)^(5-3)
Probability = 5C3(0.5)^3(0.5)^2
Probability= 5!/3!2!(0.5)^3(0.5)^2
Probability= 10(0.125)(0.25)
Probability= 0.3125
Probability of having at least 4 Girls
= 1- 0.3125
= 0.6875
Answer:

Step-by-step explanation:
5+5+12+8
Answer:.1.77
Step-by-step explanation:
e^x = 5.9
Take the natural logarithm of both sides
x = ln (59/10)
x = 1.77
Answer:
Earnings = $1960
Step-by-step explanation:
The question is incomplete; however the missing part of the question asks his total earnings if he worked for 48 hours in a week
First, we need to determine the extra hour worked
Regular Hour = 40
Extra Hour = 48 - 40
Extra Hour = 8
Total Earnings is then calculated as follows:
Earnings = Regular Hours * Regular Charges + Extra Hours * Extra Charges
Earnings = 40 * 35 + 8 * Extra Charges
Since extra charges is twice regular charges, we have:
Earnings = 40 * 35 + 8 * 35 * 2
Earnings = 1400 + 560
Earnings = $1960
