P(Head, Diamond AND Head, Heart) = ?
Answers
Using it's concept, it is found that the desired probability is given by:
P(Head, Diamond AND Head, Heart) = 1/64.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, each outcome is equally as likely, having a 1/8 probability, and they are independent.
Then:
P(Head, Diamond AND Head, Heart) = 1/8 x 1/8 = 1/64.

.To help him start a business, Cameron took out a $10,000 loan from a bank. The loan has an annual interest rate of 5%. What expectation should Cameron have?
Answers
Answer:
[tex]A = 10,000(1.05t)[/tex] where t is in years
Step-by-step explanation:
I'm going to assume that the expectation that Cameron has is the amount of money after t years.
We can use the simple interest formula [tex]A = P(1+rt)[/tex] where A is the final amount, P is the principal, r is the rate, and t is time.
We can plug in 10,000 for P and 0.05 for r, giving us
[tex]A = 10,000(1.05t)[/tex]
Using half angle identities, find an EXACT expression for sin(7π/12).

Step-by-step explanation:
We can rewrite [tex]sin(\frac{7\pi }{12} )[/tex] as [tex]sin(\frac{7\pi }{6} (\frac{1}{2} ))[/tex]. The half-angle identity for sin tells us that [tex]sin(\frac{x}{2} ) = \sqrt{\frac{1 - cos(x)}{2} }[/tex] (plus or minus). Now, we can plug in [tex]\frac{7\pi }{6}[/tex] for x.

The experimental probability of the computer generating a 2 or a 4 is 30% option fourth is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
A computer generates 50 integers from 1 to 8 at random.
Total number of outcomes = 5+8+9+7+4+6+5+6 = 50
Computer generating a 2 = 8
Computer generating a 4 = 7
P(computer generating a 2) = 8/50
P(computer generating a 4) = 7/50
P(computer generating a 2 or a 4) = 8/50 + 7/50 = 15/50 or
= 0.3×100
= 30%
Thus, the experimental probability of the computer generating a 2 or a 4 is 30% option fourth is correct.

The values of length are 100, 60, and 40 feet respectively, area of the rectangle 1000 square feet, 1800 square feet, and 1600 square feet respectively.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We know the perimeter of the rectangle = 2(w+l)
The sum of w+w+l = 120 (given)
2w + l = 120
From the above equation, we can calculate the l of the rectangle:
We have w = 10 feet
l = 100 feet
Area = 10×100 = 1000 square feet
When w = 30
l = 60 feet
Area = 60×30 = 1800 square feet
When w = 40
l = 40 feet
Area = 40×40 = 1600 square feet
Thus, the values of length are 100, 60, and 40 feet respectively, area of the rectangle 1000 square feet, 1800 square feet, and 1600 square feet respectively.
