Answer:
ME = z*s /√n
Step-by-step explanation:
The margin of error is obtained as the product of the critical value of the distribution at a certain α-level and the standard error :
The critical value = Z*
The standard error = standard deviation / √sample size
Standard deviation = s
Sample size = n
Margin of Error = z * s/√n
Answer:
i. 10 units (Carol's house is 10 units on the right from Ann's house)
ii. -10 units (Carol's house is 10 units on the left to Ann's house)
Step-by-step explanation:
A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).
In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.
Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.
Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.
So that,
The possible locations of Carol's house depends on its position with respect to Ann's house.
i. Carol's house = 8 + 2
= 10 units
This implies that Carol's house is 10 units on the right from Ann's house.
ii. Carol's house = - 8 - 2
= -10 units
This implies that Carol's house is 10 units on the left to Ann's house.
Answer:
look below
Step-by-step explanation:
The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:
P of picking card with star:
25/50=0.5
Card with square:
15/50=3/10=0.3
Card with circle: 10/50=1/5=0.2
We can then put these values into parts a,b,c, and d:
a) 3/10 chance or 30%
b) 1/5 chance or 20%
c) 1/2+1/5=7/10 chance or 70%
d) 1-0.3-0.2=1/2 chance or 50%
Answer:
