Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.
Answer: The measure of angle P = 29°
Step-by-step explanation:
We can find the interior supplementary angle at Q by subtracting
180- 56 = 124
The sum of the interior angles must be 180, so we can add ∠Q + ∠R
124 + 27 = 151
Then subtract that from 180:
P = 180 - 151
P = 29°
Answer:
Neither the normal distribution nor the t distribution applies.
Step-by-step explanation:
Hello!
The histogram attached shows the salary (in dollars) of 63 football players.
As you can see most of the values of this distribution are around 0 and the distribution is extremely asymmetrical (right skewed).
To apply a t-test to study the population average the population has to have a normal distribution.
The same goes for the standard normal distribution, but in this case, considering that the sample is large enough (n≥30) you can apply the Central Limit Theorem and approximate the distribution of the sample mean to normal X[bar]≈N(μ;δ²/n), but since the population variance is unknown, this is also not applicable.
The correct choice is the last one, since the conditions to apply the t test and the standard normal are not met.
I hope this helps!
9 square units.
the area of a triangle is 1/2 base x height.
the base of this triangle is the line RS which is 6 units long, and the height is the dashed line, which is 3 units long. 1/2 x 6 x 3 = 9
It may be B . Or it may even be wrong
