Answer:11
Step-by-step explanation:
Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
Answer:
67 degrees
Step-by-step explanation:
the shape is a tryangle so it will have the same angle measurements, just make sure you look if it has the slash next to the letter or not in the future
Hope this helps girly!!
Answer:
The slope (m) = 1/3 and the y-intercept (b) = -4
Answer:
A. Use the two-sample t-methods when a sample was taken from each of two populations (i.e. two groups being compared) and the population standard deviations are not known.
Step-by-step explanation:
T-distribution:
When the population standard deviation is not known, the t-distribution is used.
If a sample was taken from one population, we use the one-sample method, while if there is a comparison of two populations, the two-sample method is used, and thus, the correct answer is given by option A.
