To convert 400 L to mL, you would move the decimal point _ places to the _.

1 answer:

4 0

Since there are 1000mL/L, and we have 400 L, there are clearly more millileters than liters (Think of the sentence King Henry Dances Many dances come monday or KHDMdcm). The L (aka M or the base value) is to the left of the m (standing for mL), so to get from M or L to m we move the decimal point 4 places to the right to get from 400.0000 to 4,000,000

Error Analysis A problem on a test says that 70% of people enjoy the beach. The students are

Otrada [13]

Answer:

Probability that exactly one person says he or she enjoys the beach = 80%

Check Explanation for how to get this and which error the studemt that made the 100% claim must have made.

Step-by-step explanation:

The simulation presented is that for a series of two people sample.

Numbers 0 to 6 represents that the beach-goer enjoys going to the beach and numbers 7 to 9 represents that the beach-goer doesn't enjoy going to the beach.

So, the simulation is then obtained to be

(5,8) (2,7) (0,9) (0,2) (9,0) (1,9) (4,7) (0,3) (6,7) (7,5)

Using the simulation, estimate the probability that exactly one person says he or she enjoys the beach

From the simulation, the ones with exactly one of the two numbers ranging from 0 to 6 to indicate enjoying going to the beach include

(5,8) (2,7) (0,9) (9,0) (1,9) (4,7) (6,7) (7,5)

The probability of an event is defined and expressed as the number of elements in that event divided by the total number of elements in the sample space.

Probabilty that exactly one person says he or she enjoys the beach = (8/10) = 0.80 = 80%

The student claims that this probability is 100%, but the other two simulations that did not satisfy the condition of exactly one person saying that he or she enjoys the beach include

(0,2) and (0,3), which show that in the two cases, the two participants both expressed enjoying going to the beach.

The student's error must have been in counting these two simulations as part of 'exactly one person saying he or she enjoys the beach' which is indeed an error.

Hope this Helps!!!

Farmer Gray has 30 flower pots. He plants 10 seeds in each pot. How many seeds does he plant?

Alex17521 [72]

Farmer Gray planted 300 seeds.

To find this, you simply multiply the number of flower pots (30) by the number of seeds in each pot (10). Thus making the answer 300.

I hope this helps!
