20 bottles for 28
Step-by-step explanation:
15 ÷ 10 = 1.5
28 ÷ 20 = 1.4
Answer:
13 units
Step-by-step explanation:
Put the numbers in the distance formula and do the arithmetic.
d = √((x2 -x1)² +(y2 -y1)²)
= √((3 -(-2))² +(-9-3)²) = √(5² +(-12)²) = √(25 +144)
d = √169 = 13
The distance between the points is 13 units.
Answer:
.........................
Step-by-step explanation:
Answer:The answer are the red card(The second), A dependent event is an event that relies on another event to happen first.
Since he keep his first took red card,his probability to get another red card became lower,therefore it effects on what card he will take next.
the third one doesn't called a dependent event because it's a Dice,so the probability still the same
The fourth one doesn't count to,since he return back the marble.
Answer:
Step-by-step explanation:
Information given
represent the sample mean for the sample
population mean (variable of interest)
s=4.9 represent the sample standard deviation
n=8 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
the degrees of freedom are given by:
Since the Confidence is 0.95 or 95%, the value of 
and 
, and the critical value for this cae would be 
Now we have everything in order to replace into formula (1):
