Answer:
48.8°
Step-by-step explanation:
We solve using sine rule
The formula is given as
p/sin P = r/sin R
In APQR, P = 83°, p = 285 m, r = 216 m.
Calculate R.
Hence, solving for R
285/sin 83 = 216/sin R
Cross Multiply
285 × sin R = sin 83 × 216
sin R = sin 83 × 216/285
R = arc sin (sin 83 × 216/285)
R = 48.78527°
Approximately = 48.8°
Therefore, R = 48.8°
I don't know what your choices are, but I did the questions for you.
R=D/2, R=12, R=radius,
SA= 4 times 3.14 12 times 12, so,
SA=1809.557368, if you round it to two decimal places, it'll be,
1809.56, so the answer is 1809.56in. squared.
The modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
<h3>Define the term adjusted r squared?</h3>
R-squared (R2) would be a statistical measure that quantifies the proportion of the variation explained from an independent variable other variables within a regression model for a dependent variable.
- R-squared describes how much the variance with one variable describes the variance of the other.
- So, if a model's R2 is 0.50, the model's inputs can explain roughly half of a observed variation.
- A score of 70 to 100 shows that a specific portfolio closely reflects the underlying stock index, whereas a score of 0 to 40 indicates a relatively poor correlation the with index.
- Higher R-squared scores also suggest that beta measurements are more reliable. The volatility of either a security or portfolio is measured by beta.
Thus, the modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
