Mrs. lofton created a histogram of her first two test grades for her class. if she combines the two tests, what percentage of the
grades were below 70

14.29%

Step-by-step explanation:

Let's do the count for Test #1:

2 + 5 + 6 + 1 = 14 total students

Out of which, below 70 is  2 people [only the leftmost bar]

Let's do the count for Test #2:

2 + 3 + 5 + 4 = 14 total students

Out of which, below 70 is again 2 people [only the leftmost bar]

So, to find percentage of people below 70, we divide the below 70 number of people with total number of people.

(2+2)/(14+14) = 4/28 = 14.29%

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
