Your answer is D. This cannot be determined from the scatter plots.
So she has 400 and 500 so far.
now if she were to have an average of 2300 for the next 5 years, that means some years she made more, some she made less, but in the 5 years run, she made 2300 * 5 or 11500 total.
Neverminding the lows and highs, if we bundle up the 11500 bucks and divide by 5, that'd 2300, which is what's called the average, the average amount doesn't take into account that some numbers are higher than others, it kinda just flattens them out.
so in total she would have made 11500 in each account.
so in the account with 400, she needs 11100 more, how much will it be 1100 for the next three years on average? 11100/3 or 3700.
so if she earns 3700 each year, for the next 3 years in the account with 400 already, she'd have 11500 bucks in 5 years with an average of 2300.
now let's look at the 500 account, she needs 11000 more, how much will it be for 11000 for the next three years on average? 11000/3 or about 3666.67.
so if she earns 3666.67 each year, for the next 3 years, she'd have 11500 bucks in 5 yeas with an average of 2300.
The trigonometry angle range -π ≤ α ≤ π in radians means angle α is
- between -π radians and π radians or
- -180° and 180°.
To answer the question, we need to know what a trigonometric angle range is
<h3>What is a trigonometric angle range?</h3>
A trigonometric angle range is the range of values which the trigonometric angle can have
Since we need to find the meaning of the trigonometry angle range -π ≤ α ≤π.
We know that
- -π radians = -π × 180°/π = -180° and
- π radians = π × 180°/π = 180°.
Since α is in the range -π ≤ α ≤ π = -180° ≤ α ≤ 180°, this implies that the angle α is
- between -π radians and π radians or
- between -180° and 180°.
So, the trigonometry angle range -π ≤ α ≤ π in radians means that angle α is
- between -π radians and π radians or
- between -180° and 180°.
