Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.
Step-by-step explanation:
Answer:
0.0125
Step-by-step explanation:
The P-value can be calculated by using excel function T.DIST.RT(2.968,6).
Right tail is used in the function because our alternative hypothesis has greater than sign (>) whereas 2.968 represent test statistic value and 6 represents degree of freedom. The resultant p-value from excel function is 0.0125.
Or if we use t- distribution right tail area table, we see that 6 for degree of freedom the value in table is there are two value 2.44691 and 3.14627 which corresponds to p=0.025 and p=0.01. As 2.44691 is smaller than 2.968 so we take p=0.01 against 3.14627. Thus, in this scenario p-value would be 0.01.
Answer: -31.72
Step-by-step explanation:
Domain:
-4 ≤ x ≤ 3
or in different form:
x ∈ [-4; 3]
<u>Answer:</u>
- Option A (-26x² + 56x - 15) is correct.
<u>Step-by-step explanation:</u>
- [3x(-2x + 7)] - [5(x - 1)(4x - 3)]
- => [-6x² + 21x] - [(5)(x - 1)(4x - 3)]
- => [-6x² + 21x] - [(5x - 5)(4x - 3)]
- => [-6x² + 21x] - [20x² - 15x - 20x + 15]
- => -6x² + 21x - 20x² + 15x + 20x - 15
- => -26x² + 56x - 15
Hence, <u>Option A (-26x² + 56x - 15) is correct.</u>
