Answer:
Step-by-step explanation:
The ratio of the linear dimensions (perimeter) is the square root of the ratio of area dimensions, so the larger : smaller ratio is ...
√(72/50) = √1.44 = 1.2
The sum of ratio units is 1.2 + 1 = 2.2, so each ratio unit stands for ...
(226 dm)/2.2 = 102 8/11 dm . . . . . the perimeter of the smaller triangle
Then the perimeter of the larger triangle is ...
1.2 × 102 8/11 dm = 123 3/11 dm . . . . the perimeter of the larger triangle
Answer:
In Fraction = 10/100 simplified = 1/10
Decimal = 0.1
Percentage = 10%
Step-by-step explanation:
We add all marbles = 5+ 3+ 2 = 10
Event 1 = Red = 5/10
Event 2 = Green = 2/10
We follow this path and multiply = 2 x 5 / 10 x 10 = 10/100 = 1/10
Using the probability concept, it is found that:
- a) P(star) = 3/8 = 0.375 = 37.5%.
- b) P(not diamond) = 7/8 = 0.875 = 87.5%.
- c) P(flower) = 1/4 = 0.25 = 25%.
- d) You would expect to spin a heart 25 times.
------------------------------------------------
- A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
- Of the 8 sections, 3 are stars.

Then:
P(star) = 3/8 = 0.375 = 37.5%.
Item b:
- Of the 8 sections, 7 are not diamonds.

Then:
P(not diamond) = 7/8 = 0.875 = 87.5%.
Item c:
- Of the 8 sections, 2 are flowers.

Then:
P(flower) = 1/4 = 0.25 = 25%.
Item d:
- 2 out of the 8 sections are hearts, then:

Out of 100:

You would expect to spin a heart 25 times.

If we remove the 2. The others will stay the same (roughly might move by 1) EXCEPT the range. Which will drop from 12 to 4
