Answer:
q=2.61
Step-by-step explanation:
I think it's 2.61 because r+s=1.61. that plus 1 is 2.61
Here are 3= 7:1 28:4 56:8
The Answer from when you are doing the equation: Negative 8 :The answer to the question:E
Step-by-step explanation: When you add negative numbers, you are basically adding normal numbers, or atleast they look that way, you are actually subtracting but lest just pretend we are adding except they are not normal, all you have to do is add the numbers, but put a negative sign before you put in a number.
Answer:
3.60 was the tip; 27.60 was what Sam paid total
Step-by-step explanation:
24 x 0.15 = 3.6
Answer:
0.02275
Step-by-step explanation:
We use the z score formula to solve for this
z-score is given as: z = (x-μ)/σ
where x is the raw score,
μ is the population mean
σ is the population standard deviation
In the above question:
mean of μ=500
a standard deviation of SD=100
raw score x = 700
Hence, z score = (700 - 500)/ 100
= 200/100
= 2
z score = 2
Using the z score table of normal distribution to find the Probability of z = 2
P( x = z)
= P(x = 700)
= P( z = 2)
= 0.97725
P(x>700) = 1 - P(x = 700)
= 1 - 0.97725
= 0.02275
Therefore, the probability of randomly selecting an individual from this population who has an SAT score greater than 700 is 0.02275
