Find sin 2x if cos x=-2/3 and x is in quadrant 2
Answer:
-4√5/9.
Step-by-step explanation:
if cos x = -2/3 then sin x = √(1 - (-2/3)^2)
= √(5/9)
= √5/3.
(As x is in quadrant 2 sin x is positive).
So:
sin2x = 2 sin x cos x
= 2 * √5/3 * -2/3
= -4/3 * √5/3
= -4√5/9.

Next we will draw in each deviation from the mean.
Now, think about the average size (length) of all of those deviations, and use this as an estimate for the size of the
Standard Deviation. Don't worry about whether the deviation is to the left or right of the mean. Just consider all of
the lengths. Draw the length of the standard deviation below.
The standard deviation is a measure of a collection of values' variance or dispersion. The standard deviation of the below graph can be drawn as shown below.
What is a standard deviation?The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

Answer:
The biggest - the smallest
612-120=492
Answer:
612 - 120=492

Answer:
D) 471, 473, 475, 477, 479
Step-by-step explanation:
Lets say the three-digit number is ABC.
4 in the hundreds place, thus A = 4
7 in the tens place, thus B = 7.
The number is odd, therefore C = {1, 3, 5, 7, 9}
There are five possible solutions for three-digit number ABC = {471, 473, 475, 477, 479}

Jeff Krause purchased 1,000 shares of a speculative stock in January for $1.89 per share. Six months later, he sold them for $9.26 per share. He uses an online broker that charges him $10.00 per trade. What was Jeff's annualized HPR on this investment?
Thanks!
Based on the price he purchased the stock and the amount he sold them for, Jeff's annualized HPR on the investment is 2,395%.
How much is Jeff's annualized HPR?First find the net profit:
= (1,000 x 9.26) - (1,000 x 1.89) - 10
= $7,360
The HPR is:
= 7,360 / (1,000 x 1.89)
= 389.4%
The annualized HPR is:
= (1 + 389.4%)² - 1
= 2,395%
Note: Taken to the power of 2 because there are two six-month periods in a year.
