Answer:
The probability of picking two consecutive purple marbles without replacement is 14.72%.
Step-by-step explanation:
Initially, there are 4+6+2+8 = 20 total marbles.
The probability of picking a purble marble is
P_{1} = \frac{number of purple marbles}{number of total marbles}
P_{1}= \frac{8}{20} = 0.4
Since there are no replacements, there are now 19 total marbles, 7 of which are purple. So, the probability of picking another purple marble is
P_{2} = \frac{7}{19} = 0.368
The probability P of picking a purble marble(P_{1}), not replacing it, and then picking another purple marble(P_{2}) is:
P = P_{1}*P_{2} = 0.4*0.368 = 0.1472 = 14.72%
Answer:
A box plot would make it easier to see that the third quartile is 14 degrees C.
Step-by-step explanation:
On a box plot, the right end of the box gives the exact value of the third quartile. On a dot plot, you would have to identify the value based on the number of dots shown.
A)it increased by 283
b)it stays the same
A prime factor has no multiples and cant be broken down any further
Answer:
(-7, 0) are the coordinates of the function.
Step-by-step explanation:
The given function is f(x) = (x²+3x-28)/(x+7).
We have to find the coordinates of hole of the given function.
To find the coordinates of the hole we will find the factors of the numerator first.
x² + 3x - 28 = x²+ 7x - 4x -28
= x(x + 7) - 4(x + 7)
= (x + 7)(x - 4)
Now we know that factor (x + 7) is common as denominator therefore these factors will get cancelled.
Therefore x + 7 = 0
Or x = -7
and for x = -7 the value of y = (x²+3x-28)/(x+7) = 0
Therefore the coordinates of the hole of the given function is (-7, 0).
