Answer:
7
Step-by-step explanation:
It is 7:
31 - 7 = 24
15 - 7 = 8
8/24 = 1/3 = 33%
It is not 12:
31 - 12 = 19
15 - 12 = 3
3/19 = 15%
It is not 6:
31 - 6 = 25
15 - 6 = 9
9/25 = 36%
It is not 9:
31 - 9 = 22
15 - 9 = 7
7/22 = 31%
It is not 11:
31 - 11 = 20
15 - 11 = 4
4/20 = 20%
<u>I subtracted the option from 31 (the new total of marbles) and from 15 (the new total of blue marbles). Then, I divided the new total by the new total of the blue marbles. I converted the decimal into a percentage. If the percentage was not 33%, then it was not the answer.</u>
If angle TSV=6x+17 then arc it intercept (SV)would be double it
6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7
Arc SV=15(7)+13
=118
And angle TSV=6(7)+17
=59
There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360
Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242
Answer: -37
Step-by-step explanation:
6 more than a number would make an equation of 6+x=-31. Subtract 6 on both sides to get x=-37
Answer:
0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
N(489,6)
This means that
What is the probability that the box will contain less than the advertised weight of 466 g?
This is the p-value of Z when X = 466. So
has a p-value of 0.000064
0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.
