Answer: 200
Step-by-step explanation:
first, you set up your proportion. (23% at the top right, 100 at the bottom right, 46 at the top left, and x and the bottom left.) next, you multiply x * 23% = 23x then 46*100 = 4600. 4600 divided by 23 = 200. therefore, x = 200. please let me know if you have further questions!
Good luck !
Answer:
Least value of the smaller number is -8.
Step-by-step explanation:
Let the smaller number be x and the higher one y.
So y = x + 12 and
xy = -32
Substitute for y in the second equation:
x(x + 12) = -32
x^2 + 12x + 32 = 0
(x + 8)(x + 4) = 0
x = -4, -8.
So the least value of the smaller number x is -8.
((p^2)-pq) - ((q^2)-pq)
(p^2) - (q^2) - 2pq
The figure is really just 3 triangles and 1 rectangle, as you see in the picture below.
notice the blue triangle has a base of 3 and a height of 2,
the green triangle has a base of 6 and a height of 1,
the yellow triangle has a base of 2 and a height of 6,
and the rectangle is a 7x6 rectangle.
we can simply get the area of each and sum them up, that's the area of the figure.
Answer:
Option B) data from the sample is used to estimate the population parameter
Step-by-step explanation:
Point estimation:
- Its is the process of getting a point estimate from a sample that describes a population parameter in the best way.
- We calculate the unknown population parameter with the help of a sample drawn from the population.
- It is similar to interval estimation.
- In interval estimation we obtain an interval in which the population parameter may lie but in point estimation we obtain a single value which is the best approximation of population parameter.
Thus, the correct answer is
Option B) data from the sample is used to estimate the population parameter
