earthworms he can have if his square of compost has a side length that is 3 times longer .
<u>Step-by-step explanation:</u>
Here we have , Hiram raises earthworms. in a square of compost 4ft by 4ft he can have 1000 earthworms. We need to find how many earthworms can he have if his square of compost has a side length that is 3 times longer .
Area of square compost =
⇒
⇒
⇒
In this , square compost with can have 1000 earthworms ! if side is 3 times longer i.e. New side = , So , new area will be :
⇒
⇒
⇒
⇒
Now , can have 1000 earthworms ,So will have :
⇒
⇒
Therefore, earthworms he can have if his square of compost has a side length that is 3 times longer .
Though the vectors are going in opposite directions, their terminal and starting points are the same, just switched, check the picture below.
recall the component for (a,b), (c,d) is just (c-a , d-b),
the component form for "v" is then
(5, -4), (15, 22) => (15 - 5, 22-(-4)) => (15 - 5, 22+4) => (10 , 26).
and since "v" is twice as long as "u", then its form is 2v, or
2(10 , 26) => (20, 52)
Answer:
B, D, and E
Step-by-step explanation:
The original price was $48
If 75% was 36, divide it by three to get 12 then multiply 12 by 4 to get 100% = 48
Answer:
apart from using the hoc to predict the college students gpa, some other variables can be used
1. the students intelligent quotient
2. ability to remember
3. study time
4. gym practice
Step-by-step explanation:
<u>1. the students intelligent quotient</u>
<u>gpa</u><u> </u>has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.
2. <u>ability to remember</u>
the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction
3. <u>study time</u>
gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.
4. <u>gym</u><u> </u><u>practice</u>
gpa and gym practice are not related so the slope would be in a downward direction.
when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.
