Hello,
Meredith has k toys and Gazali too
Meridith gives 20/100 * k
Gazali gives 85/100*k
So they gives 105/100 * k toys which is 126
105/100 *k=126
k=126*100 /105
They have left alltogether 80/100 * k + 15/100 *k= 95/100 *k
95/100*k=95/100* 126*100/105=114 (toys left).
Answer:
A. Positive
Step-by-step explanation:
They ask us about the relationship between reading and grades.
First you have to go to the first part of the statement that says:
"Dr. Yancy conducted a correlation study in which she found that the more time children in her study read at home the better they performed in school"
In this case they tell us that there is a positive correlation, that the more you read the better your performance in school is.
Performance is your grades, and home study can be reading, so the score is positive in the second half, too.
I think you mean 48. 4 * x = 48. x = 48/4 = 12
