Answer:
They are not equivalent expressions
Step-by-step explanation:
y + 6 = 15
y = 9
3(y + 6) = 15
y + 6 = 5
y = -1
Answer:
a) Figure attached
b) For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Step-by-step explanation:
For this case we define the random variable X= depth (in centimeters) of the bioturbation layer in sediment for a certain region, and we know the distribution for X, given by:
Part a
For this case we can see the figure attached.
Part b
For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Slope is rise/ run, or change in y/ change in x. the error was that the person out run/rise, so the correct answer is 4/6.
Answer:
6 laps.
Step-by-step explanation:
On Monday she runs 2x + 8 miles, where x miles = the length of the trail.
On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so
2x + 8 = 4x + 4
4 = 2x
x = 2 miles which is the length of the trail.
So each day she runs 4(2) + 4 = 12 miles.
So on Saturday she runs 12/ 2 = 6 laps.
Answer:
70% of the meeting is left.
Step-by-step explanation:
Hi, to answer this question, first, we have to convert the hours to minutes.
Since 1 hour = 60 minutes
For 2 hours:
1 /60 = 2/x
x = 2 (60)
x = 120 minutes
So, a scout meeting last 120 minutes (2 hours)
36 minutes already spent.
120-36 = 84 minutes left
So, if 120 is the 100% of the meeting, for 84 minutes:
120/100 = 84/x
1.2 =84/x
x = 84/1.2
x = 70%
70% of the meeting is left.
