Answer:
x <= -6.33333
(>= is greater than or equal to)
(<= is less than or equal to)
Step-by-step explanation:
7 - 3(x+5) >= 11
7 - 15 - 3x >= 11
-8 - 3x >= 11
-3x >= 19
x <= 19/-3
x <= -6.33333

Step-by-step explanation:
given:
5 steps------> equivalent to 12 feet
1 step -------> equiv. to 12/5 feet
500 steps ----> equiv to (12/5) x 500 = 1200 feet
A researcher used simple random sampling in collecting grade-point averages of statistics students. From there, he calculated the mean of the sample.
The question: “Under what conditions can the sample mean he got be treated as a value from a population having a normal distribution?” can be answered by the central limit theorem which states that: Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean N approaches a normal distribution. if sample size, increases. The researcher needs to increase the number of statistics students so the variance of the sampling distribution of the mean will become smaller.
Answer:
it's been good thanks, how was yours?
Step-by-step explanation:
Answer:
math has:30
game has:26
Step-by-step explanation:
math⇒x
game⇒y
x+y=56
x=y+4
so y+4+y=56 ⇒2y+4=56
⇒56-4 ⇒2y=52⇒y=52/2⇒26
and if y = 26 then x=30
