Answer:
C. p > -3
Step-by-step explanation:
We observe the characteristics of the shaded ray on the number line.
It goes to the right, so the inequality must be either greater than or greater than or equal to.
The circle where it starts on is open, so the inequality must not be less than or equal to or greater than or equal to.
Now, without even looking at the numbers themselves, we can find our answer.
There are four different types of inequalities, and we eliminated three of them (<, <=, >=). This leaves only one left (>). The only answer choice that uses the greater than symbol is C, so it must be our answer.
Answer:
the answer to 9 is c, and to 10 is c
Step-by-step explanation:
36 ans 48 can both be divided by 12 to find their ratio
24 and 120 can both be divided by 24 to find their simplest form
Y=5(1.5)^x
I divided 16.875 by 7.5, which is 2.25 Since the multiplier was used twice, I found out the square root of 2.25, which is 1.5. So now we know that the multiplier is 5.
Then I divided 7.5 by 1.5 to get the initial value, since 7.5 is the value in the first spot. 7.5 divided by 1.5 is 5.
Multiplier = 1.5
Initial Value = 5
y=5(1.5)^x
Answer:
The probability that the plane is oveloaded is P=0.9983.
The pilot should take out the baggage and send it in another plain or have less passengers in the plain to not overload.
Step-by-step explanation:
The aircraft will be overloaded if the mean weight of the passengers is greater than 163 lb.
If the plane is full, we have 41 men in the plane. This is our sample size.
The weights of men are normally distributed with a mean of 180.5 lb and a standard deviation of 38.2.
So the mean of the sample is 180.5 lb (equal to the population mean).
The standard deviation is:
Then, we can calculate the z value for x=163 lb.
The probability that the mean weight of the men in the airplane is below 163 lb is P=0.0017
Then the probability that the plane is oveloaded is P=0.9983:
The pilot should take out the baggage or have less passengers in the plain to not overload.
Answer:
A. 3x - 1 + [3x - 1]⁻¹
Step-by-step explanation:
Use Polynomial Long Division to arrive at this answer.
**[3x - 1]⁻¹ = 1\[3x - 1]
