Answer:
One-sample Z-test
Step-by-step explanation:
As the sample size is greater than 30, assuming the data is a simple random sample, and that the data has a normal distribution, the sociologist should conduct a one-sample z-test to calculate the p-value.
Answer:
12x³ meters
Step-by-step explanation:
Area/Width = Length
Length = 144x⁴/12x
= 12x³
Answer:
64°
Step-by-step explanation:
Set the measure of the original angle as x.
The measure of its supplement would be 180-x.
Thus,
x = 0.5 * (180-x) + 6
x = 90 - 0.5x + 6
1.5x = 96
x = 64°
Answer:
easy peasy lemon squeazy
Step-by-step explanation:
in this circle, BC is the diameter,
hence, BCA is a semicircle,
and we know that, angle subtended by a semicircle at any point inside the semicircle is 90°,
therefore by angle sum property of triangles, we have
in ΔABC
∠A + ∠B + ∠C = 180°
=> 90° + 50° + ∠C = 180°
=> ∠C = 180° - 140°
=> ∠C = 40°
