Answer:
38°
Step-by-step explanation:
EFGH is an isosceles trapezoid (a trapezoid with two congruent legs is isosceles)
∠HGF=70° (base angles of an isosceles trapezoid are congruent)
∠EGH=32° (angles in a triangle add to 180°)
∠FGE=38° (angle subtraction postulate)
Answer:
0.353
Step-by-step explanation:
We have been given that a history class is comprised of 7 female and 10 male students.
We will use combinations to solve our problem.
We can choose 6 female students out of 7 female students in ways.
We can choose 7 male students out of 10 male students in ways.
So the number of ways that 6 female and 7 males can be chose is: 7*120 = 840.
Now let us find ways in which 13 students can be chosen from 17 students as:
Now let us substitute our values in probability formula.
Therefore, the probability of selecting 6 female students and 7 male students is 0.353.
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)
Answer:
2.576
Step-by-step explanation:
Given :
Confidence level (α) = 99%
Z(1 - α)/2 = Z(1 - 99%)/2
Z1%/2 = Z1%/ 2
Z0.5% = Z0.005
Z(0.99 + 0.005) = Z0.995
Using the Z distribution table ; locate the z value for the proportion 0.995 ; this corresponds to approximately 2.57
Similarly, using the Invnorm calculator function :
Invnorm(0.995) gives a Zscore of :
2.576
