The ratio of cm to mi is 1/30, and we are looking for x/110. Since 1/30 = x/110, 30x=110.
x = 110/30 = 11/3 = 3.7 cm
Answer:
11/15
Step-by-step explanation:
There are 8 marbles total. If they are being selected from twice with one missing, we could add 8 and 8 - 1 together to get the denominator for the probability.
8 + (8 - 1) = 15
We have to assume the first marble taken was red, so we will have 6 plus 6 - 1 red marbles to choose from for our numerator.
6 + (6 - 1) = 11
The probability of consecutively selecting two red marbles is 11/15.
Answer:
C. obtaining an even number when rolling a die
Step-by-step explanation:
Two events are independent when neither depends on the other. That is, the probability that one occurs is not affected by the occurrence, or lack of occurrence, of the other event. Their joint probability is the product of their individual probabilities.
__
Among the answer choices, all describe two independent events except C. Choice C describes one (1) event, so does NOT illustrate independent events.

4/15
Step-by-step explanation:
4/5 ÷ 3 =
4/5 x 1/3 = 4/15
Answer:
29.5 square inches
Step-by-step explanation:
Let's divide the shape into 3 parts to make it easy for us to find the area.
- a wide triangle
- a triangle
- a shorter rectangle
For the wider rectangle, the area is;
A1 = 8 × 2 = 16 in²
For the triangle, the area is;
A2 = ½(7 - 2) × 3
A2 = 7.5 in²
For the shorter rectangle, the area is;
A3 = 3 × 2
A3 = 6 in²
Total area = A1 + A2 + A3 = 16 + 7.5 + 6 = 29.5 square inches
