Answer:
0.04
Step-by-step explanation:
Answer: a) 15:26, and b) 15:11.
Step-by-step explanation:
Since we have given that
Number of graded tests = 15
Number of total tests = 26
Number of ungraded tests is given by

a) Proportion of all exams has Dr. Fitxgerald graded is given by
15:26.
b) Ratio of graded to ungraded tests is given by 15:11
Hence, a) 15:26, and b) 15:11.
Answer:
UNLIKELY
Step-by-step explanation:
Given that:
Probability of rolling a six with a six sided nuner cube = 1/6
Required outcome / Total possible outcomes
Number of 6 / total sides of number cube = 1/6
The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.
Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'
Answer:
3 + 5i.
Step-by-step explanation:
(2−√−4)+(1+√−49)
√−4 = 2i and
√−49 = 7i.
So (2−√−4 + (1+√−49
= ( 2 - 2i) + (1 + 7i)
= 3 + -2i + 7i
= 3 + 5i.
