Answer:
Step-by-step explanation:
Given:
Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).
So, the 'x' value is 3 and 'y' value id -4.
Using Pythagoras Theorem, we find the hypotenuse.
Hypotenuse = 
Now, using the sine ratio for the angle, we have
Therefore, the value of 
is 
.
The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
I think it’s 15.84
because the formula is v = 1/3bh
Answer:
0.013
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
and p is the probability of success.
Given n = 6, p = 0.69, and r = 0 or 1:
P = ₆C₀ (0.69)⁰ (1−0.69)⁶⁻⁰ + ₆C₁ (0.69)¹ (1−0.69)⁶⁻¹
P = (1) (1) (0.31)⁶ + (6) (0.69) (0.31)⁵
P = 0.013
Answer:
The answer is D
Step-by-step explanation:
The solution would be like this for this specific problem:
Cost of the computer:
i = 0.117 / 12
i = 0.00975
= monthly payment
= (i * P * (1 + i)^n) / ((1 + i)^n - 1)
= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1)
= $55.32
Electricity cost:
= $0.79 * 365.25 * 7
= $2019.83
Electricity Percentage:
= $2019.83 / ($2019.83 + $1659.60)
= 54.89%
Electricity:
= ($0.79 * 365 * 5) + ($0.79 * 366 * 2)
= $2020.03
Electricity Percentage:
= $2020.03 / ($2020.03 + $1659.60)
= 54.898%
In total, the electricity made up 54.898% of the lifetime cost of the computer.
The next 3 equivalent ratios are
4:2
6:3
8:4
10:5
Hope this helps!
