The mode of given data set is 74. Option D is correct option.

Step-by-step explanation:

We need to find mode of the data set

The data according to key is: 5|0 = 50 years old

So, data will be:

50,54,56,60,62,63,64,68,68,69,70,72,73,74,74,74,78,79,84,85,86,88

Mode is the most repetitive value in the data set.

So, the most repetitive value is 74.

The mode of given data set is 74. Option D is correct option.

Ahmed solved x/2 - 3 = 6. His result was x = 15

adelina 88 [10]

Part (a)

Let's replace x with 15 and evaluate to see if he is correct or not.

x/2 - 3 = 6

15/2 - 3 = 6

7.5 - 3 = 6

4.5 = 6

We get a false statement after simplifying everything. We need to get the same number on both sides to get a true statement. Therefore, Ahmed is not correct.

<h3>Answer: No, he is not correct</h3>

===============================================

Part (b)

Let's solve for x. We do so by first adding 3 to both sides, and then multiplying both sides by 2. This follows PEMDAS in reverse, undoing everything to isolate the variable.

x/2 - 3 = 6

x/2 = 6+3 .... add 3 to both sides

x/2 = 9

x = 9*2 .... multiply both sides by 2

x = 18 is the answer

As a check, we'll use the same idea as part (a)

x/2 - 3 = 6

18/2 - 3 = 6

9 - 3 = 6

6 = 6

We get a true statement this time. This confirms x = 18

<h3>Answer: x = 18</h3>

jamie volunteers at the pet shelter every 3 days and at the food pantry every 6 days. this month he volunteers at the pet shelte

denpristay [2]

Answer: No. Jamies reasoning doesn't make any sense.

Counter example :- Isha decides to go on walk on every 4th day and go for gym on every 2nd day in a month.

Then Isha will do both the things on same day = LCM (4,2)

Now, LCM of 4 and 2 = 4

Therefore, Isha will do both the things on 4th day of the month .

Step-by-step explanation:

Jamies reasoning doesn't make any sense.

Because the LCM of 3 and 6 = 6 not 18[since 6=3×2]

LCM is the least common multiple number of two or more numbers.

Find the widest range of scores that you can get on a final exam in order to receive a grade of B for the class. Using interval

Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

$\dfrac{96+77+74+x}{4}.$

Since you must have an average between 80% and 89%, then

$80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.$

X is measured in percent, then the greatest value of x can be 100%. You get that

$73\%\le x\le 100%.$
