11,000 or 10,000 or 11,200 or 11,230
Answer:
22 + x ≤ 40
x ≤ 18 pounds
Step-by-step explanation:
Maximum weight = 40 pounds
Initial weight = 22 pounds
Let Maximum weight that can be added = x
Mathematically, this means :
Initial weight + additional weight ≤ 40
That is ;
22 + x ≤ 40
Additional weight, x :
x ≤ 40 - 22
x ≤ 18 pounds
The survey was intended for Bill's middle school during the summer. The
survey was administered to students of other schools on a Saturday.
- The type of error is the <u>selection bias error</u>.
Reasons:
The type of error made is a non sampling error, given that the target of the
study is the number of times in a week students at his middle school
attend the beach during the summer.
The errors are; Selection bias error.
- The given that the students survey are not from his middle school.
- The survey was carried out once on a Saturday, where the target was during the summer.
The selection bias error is a type error that is due to the researcher
chooses what to study, such that the participant have common
characteristics rather than being random.

A square, rectangle, rhombus (I think)
Answer:
3
Step-by-step explanation:
A dog buried 18 bones
On Monday he dug up 1/2 of the bones
On Tuesday he dug up 1/3 of the bones
= 1/2 × 18
= 9
= 1/3×18
= 6
Therefore the remaining bones still buried in the ground can be calculated as follows
= 9+6
= 15
= 18-15
= 3
Hence 3 bones are still buried in the ground
