In one day, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda. Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk. Marian consumes 510 calories by drinking 3 servings of milk and 1 soda. Using matrices to solve, how many calories are in 1 serving of milk?A. 90
B. 110
C. 130
D. 180​

Answers

Answer 1
Answer:

Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories

How to solve Linear Programming problems?

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

Thus, for Joe, equation to show amount of calories is;;

2x + y + z = 530    -----(1)

For Darius, equation to show amount of calories is; ;

x + 2y = 370     ------(2)

For Marian, equation to show amount of calories is;

3x + z = 510    ------(3)

Using matrix calculator online to calculate this 3 equations, we have;

x = 110 calories.

Answer 2
Answer:

Answer:

the answer is B on ed2020

Step-by-step explanation:

for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.

so you have soda = 180 cal and juice = 130 cal

if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct

Wayne Inc., a health insurance company, pays clerks an incentive based on the average amount of work completed per hour. Wayne pays $10 for processing 20 invoices per hour. An employee who processes 30 invoices would earn $15 per hour. Hence, Wayne pays the same rate per invoice no matter how many invoices an employee processes per hour. Which type of incentive pay does this scenario illustrate?

A 12-gallon tub has a faucet that lets water in at a rate of 3 gallons per minute, and a drain that lets water out at a rate of 1.5 gallons per minute. If you start with 3 gallons of water in the tub, how long will it take to fill the tub completely?

Answers

Vol of water required to fill up the tub = 12-3 = 9
Rate of water per min  =    3 -1.5  = 1.5/min
Using the formula           vol   =   rt
                                            t = v/r
                                            t =    9/1.5    =   6
  time taken  =    6 mins



Legalization of marijuana, Part 1. The 2010 General Social Survey asked 1,259 US res- idents: "Do you think the use of marijuana should be made legal, or not?" 48% of the respondents said it should be made legal. (a) Is 48% a sample statistic or a population parameter? Explain. (b) Construct a 95% confidence interval for the proportion of US residents who think marijuana should be made legal, and interpret it in the context of the data. (c) A critic points out that this 95% confidence interval is only accurate if the statistic follows a normal distribution, or if the normal model is a good approximation. Is this true for these data? Explain. (a) A news piece on this survey's findings states, "Majority of Americans think marijuana should be legalized. Based on your confidence interval, is this news piece's statement justified?

Answers

Answer:

see below

Step-by-step explanation:

(a) 48% is a sample statistic because it's based on the responses of 1,259 US residents. It's used to estimate a population parameter.

(b) We can calculate a 95% confidence interval for the proportion of US residents who support marijuana legalization. This interval provides a range, and we can be 95% confident that the true proportion falls within this range.

(c) The confidence interval calculation assumes the data follows a normal distribution. To use this method, we need a sufficiently large sample size, which is met in this case.

(d) To justify the news piece's statement that a majority of Americans support marijuana legalization, we need to check if the confidence interval includes values above 50%. If it does, then it supports the statement.

In Art class, Mr. Joselyn gave everyone a 1-foot stick to measure and cut. Vivian measured and cut her stick into 5 equal pieces. Scott measured and cut his into 7 equal pieces. Scott said to Vivian, "The total length of my stick is longer than yours because I have7 pieces, and you only have 5." Is Scott correct? Use words, pictures, or a number lone to help you explain.

Answers

Scott is incorrect, because Mr. Joselyn gave everyone a 1-foot stick, meaning everyone's stick has a total length of 1-foot.  The amount of pieces the stick was cut into does not factor into the length of the stick.
