Answer 1
Answer:

Answer:

Gemma gets 3 biscuits

Zak gets 18 biscuits

Step-by-step explanation:

1:6 = 1+6

= 7

1/7 * 21 = 3

6/7 * 21 = 18
Answer 2

A cocktail nut mix should have the following minimum requirements in a can of 1 pound being sold at $3.99 a can at retail stores. The following information is given: Nut Type Minimum Amt Maximum Amt Cost per pound Almond 10% 100% $2.75 Peanut 0% 50% $0.55 Walnut 20% 100% $1.70 Cashew 0% 40% $1.20 The can costs $0.10. Find the proportion of these nuts by weight to maximize the profit of the nut manufacturer. Use those proportions to select the answer closest to the profit that can be made per can if it is sold to the retail store at $3.00 a can. Group of answer choices $1.65 $1.35 $2.76 $1.77
An insurance company writes policies for a large number of newly-licensed drivers each year. Suppose 40% of these are low-risk drivers, 40% are moderate risk, and 20% are high risk. The company has no way to know which group any individual driver falls in when it writes the policies. None of the low-risk drivers will have an at-fault accident in the next year, but 10% of the moderate-risk and 20% of the high-risk drivers will have such an accident. If a driver has an at-fault accident in the next year, what is the probability that he or she is high-risk

Maria found the least common multiple of 6 and 15. Her work is shown below.Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . .

Multiples of 15: 15, 30, 45, 60, . . .


The least common multiple is 60.


What is Maria’s error?

the answer is IDK

Answers

Answer:

The Least Common Multiple is 3

Step-by-step explanation:

Maria's error was that she tried finding the largest multiple rather than the least.

Answer:

Step-by-step explanation:

Maria's error on this is the LCM is 30 not 60

the least is 30 not 60

You go to school in a college town. You know that there are 2000 students enrolled in the school, but you don’t know the population of the town (without students). You walk up and down the main streets of the town, stop people, and ask them if they are students or not. You ask 100 people, and 60 of them say they are students. Estimate the nonstudent population of the town.

Answers

2,000/100=20
40*6=240
I hope got it correct
240 non students

Right or leftMost people are right-handed, and even the right eye is dominant for most people. Molecular biologists have suggested that late-stage human embryos tend to turn their heads to the right. In a study reported in Nature (2003), German bio-psychologist OnurGüntürkün conjectured that this tendency to turn to the right manifests itself in other ways as well, so he studied kissing couples to see which side they tended to lean their heads while kissing. He and his researchers observed kissing couples in public places such as airports, train stations, beaches, and parks. They were careful not to include couples who were holding objects such as luggage that might have affected which direction they turned. For each kissing couple observed, the researchers noted whether the couple leaned their heads to the right or to the left. They observed 124 couples, ages 13–70 years. Suppose that we want to use the data from this study to investigate whether kissing couples tend to lean their heads right more often than would happen by random chance.​The symbol π represents the long-run proportion of all the couples that lean their headsleftrightwhile kissing.Which of the following best describes the null hypothesis and the alternative hypothesis using π?null: π ≠ 0.5, alternative: π > 0.5null: π = 0.5, alternative: π < 0.5null: π = 0.5, alternative: π > 0.5null: π ≠ 0.5, alternative: π < 0.5Of the 124 kissing couples, 80 were observed to lean their heads right. What is the observed proportion of kissing couples who leaned their heads to the right? What symbol should you use to represent this value? (Round answer to 3 decimal places, e.g. 5.275)p^=the absolute tolerance is +/-0.001Determine the standardized statistic from the data. ​(Hint: You will need to get the standard deviation of the simulated statistics from the null distribution.) (Round answer to 2 decimal places, e.g. 52.75)z = the absolute tolerance is +/-0.02Interpret the meaning of the standardized statistic.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations above the null hypothesized value of 0.50.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations away from the null hypothesized value of 0.50.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations below the null hypothesized value of 0.50.Select the best conclusion that you would draw about the null and alternate hypotheses.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is more than 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is less than 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is near to 50%.
