Answer:

d. The point value of a test item is more than 1.25 points and less than 1.5 points.

Step-by-step explanation:

Write the inequality for each scenarios, as follows:

a. defining x: container of milk cost. Data: x is at least $1.25 but less than $1.50. These mean that x >= $1.25 and x < $1.5, because $1.25 is included but $1.5 is not.

b. defining x: minutes spent on homework by the student. Data: x is at least 1.25 hours ( 1 hour 15 minutes) but no more than 1.5 hours (1 hour 30 minutes). These mean that x >= 1.25 h and x < 1.5 h, because 1.25 h is included but 1.5 h is not.

c. defining x: tip added to a restaurant bill. Data: x  is less than or equal to 1.25 (addition of 25% to the bill) or less than or equal to 1.5 (addition of 50% to the bill). In the first case x <= 1.25 and in the second one x <= 1.5

d. defining x: the point value of a test item. Data: x  is more than 1.25 points and less than 1.5 points. These mean that x > 1.25 and x < 1.5

In consequence, only the last scenario can be represented by the inequality 1.25 < x < 1.5.

steve has quiz scores of 60,64,75,71. If all the quizzes count the same, what is the lowest grade he can make on the next quiz t
NeX [460]

Answer:

The last quiz score must be at least an 80 to get the average to be a 70.

Step-by-step explanation:

In order to find this, you need to take the average of the 4 test scores along with the unknown test score (x). So, to find an average, we add all the numbers together and divide by the amount of tests taken. We can then set this equal to 70 since that is the minimum average.

(60 + 64 + 75 + 71 + x)/5 = 70 ------> Multiply both sides by 5

(60 + 64 + 75 + 71 + x) = 350 -----> Combine like terms

270 + x = 350 -----> Subtract 270 from both sides

x = 80

Suppose we went to choose 2 letters without replacement from 3 letters a b and c
vagabundo [1.1K]

Answer:

6 ways -  ab,ac, ba,bc and ca,cb

Step-by-step explanation:

We are given 3 letters a,b,c.

We can choose the first letter in 1 out of 3 ways.

Once the first letter has been chosen without replacement, we have two letters remaining. Another letter can be chosen from the 2 remaining letters in  2 ways. So the total number of ways of choosing the two letters is 3*2 = 6.

Listing out the possible set of choices:

Options include: ab,ac, ba,bc and ca, cb
