Four equivalent expressions for 90+21
Answers
So it could be 91 + 20, 68 + 43, 45 + 66, 75 + 36, etc.
Final answer:
The four equivalent expressions for 90 + 21 can be represented as separate sums, number line jumps, or real world problems, all of which equal 111.
Explanation:
The student has asked for four equivalent expressions for 90 + 21. Here are four possible representations:
- Adding the subsequent numbers in a sequence where the numbers are 90 and 21, which simplifies to 111.
- Calculating the total value of two separate groups, one of 90 and another of 21, which when combined gives 111.
- A number line representation where one starts at position zero and makes two jumps, one of 90 units and a second jump of 21 units, which lands at 111.
- A real-world problem where one has 90 of something and is given 21 more, resulting in a total of 111.

Answer:
Step-by-step explanation:
it is continuous in [0,3]
f'(x)=2x which exists in (0,3)
f(0)=0²+5=5
f(3)=3²+5=14
f(0)≠f(3)
so Rolle's theorem can't be applied.

P ( P + W ) = 7/9 * 2/8 = 7/36
2. The probability of selecting two white marbles:
P( W + W ) = 2/9 * 1/8 = 1/36
3. P ( P +P ) = 7/9 * 6/8 = 21/36 = 7/12
The probability of selecting 2 purple marbles in a row is much greater than selecting two white marbles.
The probability of selecting a purple marble and then a white marble is 0.19.
The probability of selecting two white marbles is 0.03.
The probability of picking two purple marbles is greater.
What are the probabilities?
Probability is used to determine the likelihood that an event would occur.
The probability of selecting a purple marble and then a white marble = (number of purple marbles / total number of marbles) x (number of white marbles / total number of marbles- 1)
7/9 x 2/8 = 0.19
The probability of selecting two white marbles = (number of white marbles / total number of marbles) X (number of white marbles / total number of marbles- 1)
2/9 X 1/8 = 0.03
The probability of selecting two purple marbles = 7/9 x 6/8 = 0.58
