Answer:
the answer is in the photo below
Answer:
The first piece is 12 feet long, the second is 9 feet long, and the third is 4 feet long.
Step-by-step explanation:
The original rope is 25 feet in length. Two pieces are dependant on the value of , so we must first find that. The equation for the length of rope is:
The terms with can be combined:
Now, take 4 from both sides:
And divide by 7:
Now we just use the value found for to find the lengths of the rope:
To check the answer, we can make sure the three lengths sum to 25 feet:
Which it does. So the three lengths are 12 feet, 9 feet and 4 feet.
Answer:
a) 0.923
b) 0.957
c) 0.88
d) 0.077
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40
Standard Deviation, σ = 14
We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.
Formula:
a) P(xis less than 60)
P(x < 60)
Calculation the value from standard normal z table, we have,
b) P(x is greater than 16)
Calculating the value from the standard normal table we have,
c)P(x is between 16 and 60)
d) P(x is more than 60)
P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
-19 is the answer cuz 1-10-10 is -19.
Answer:
In the middle because half of 50 inches is 25 inches.
