Because there are no red marbles on the bag, we will see that the probability is zero.
<h3>
How to find the probability?</h3>
We want to find the probability that the marble will be red. Viktoria knows that her bag has no red marbles, then it is impossible to get a red marble.
The probability of an impossible event is 0 (suppose that there are 10 marbles in the bag, we have a probability of 0 out of 10 of getting a red marble).
Then we can write the probability as P = 0.

Step-by-step explanation:
Answer:
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions
Step-by-step explanation:
Let
Number of multiple-choice questions = x
Number of open-ended questions = y
x + y = 38 (1)
4x + 20y = 200 (2)
From (1)
x = 38 - y
Substitute x = 38 - y into (2)
4x + 20y = 200
4(38 - y) + 20y = 200
152 - 4y + 20y = 200
- 4y + 20y = 200 - 152
16y = 48
y = 48/16
y = 3
Substitute y = 3 into (1)
x + y = 38
x + 3 = 38
x = 38 - 3
x = 35
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions
Answer:
56.5 cu.in
Step-by-step explanation:
Diameter is 6 inches,then radius(r)=3 inches
volume of hemisphere=2/3πr^3
=2/3×3.14×3×3×3
=2×3.14×3×3
=2×3.14×9
=56.52 cu.in
