Answer:
sampling error is not known
Step-by-step explanation:
Probability sampling may be defined as the sampling technique where the researcher or the experimenter chooses the samples from the larger population group using such method that is based on probability theory.
While non probability sampling is the kind of sampling method which is not feasible or possible for random sampling. It is the opposite of the probability sampling method. Here, the odds of any individual to be selected for any sample cannot be calculated.
The difference between the two is that the sampling error is not known.
Answer: i think its c.
Step-by-step explanation: if one group had a $51,000 salary, then so so would the other group. to me it seems it depends how hard the teacher worked, but i believe it is c.
hope this helped you!
Answer:
Step-by-step explanation:
Let h be the cylinders height and r the radius.
-The volume of a cylinder is calculated as:
-Since the cone is within the cylinder, it has the same radius as the cylinder.
-Let be the height of the cone.
-The area of a cone is calculated as;
The volume of the solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:
Hence, the approximate area of the solid portion is
<span>The measure of angle dcb is 120</span>°.<span>
Because in a parallelogram, Consecutive angles are supplementary that means (D + C = 180°).
given that angle adc is equal to 60</span>°
So, ∠adc + ∠dcb = 180°
60 ° + ∠dcb = 180°
∠dcb = 180 - 60 = 120°
Thus, the measure of angle dcb is 120°.
Answer:
C (as marked)

The purpose of each of the equations is to express the total cost of the described purchase. If x is the cost of a hamburger, then the cost of two hamburgers is 2x. Likewise if y is the cost of a drink, then the cost of 5 drinks is 5y. The total cost of 2 hamburgers and 5 drinks will be ...
2x +5y
This value is said to be $23, so the appropriate equation for this relation is ...
2x +5y = 23 . . . . . part of answer choice C only
