Given:
The table and the relative frequency histogram show the distribution of the number of tails and three coins are tossed.
To find:
The probability .
Solution:
In the given table T represents the number of tails.
From the given table it is clear that the value of probability is and . So,
Therefore, the probability is equal to .
Answer:
FFFFFFFFFFFFFFFFFFFFF
Step-by-step explanation:
Well first off those numbers add up to 163.
A way to check this is to add 52 with 23 which is 75 then add 78 by 10 which is 88 now add 75 with 88 which is 163
Answer:
C. 79%
Step-by-step explanation:
The probability of the pebble inside the circle will depend on the area of the circle. I assume that the circle is inside the square surface and has the diameter(d) the same as the square side(s). If the radius equal to half diameter, the area for the circle will be:
circle area = pi * r * r
circle area= 3.14 * (0.5d) * (0.5d)
circle area=0.785 d^2= 0.785 s^2
The total area where the stone can land is equal to the square area. The area of the square is:
square area= side * side= s^2
Then the chance for the pebble land on the circle is:
circle area/ square area= 0.785 s^2 / s^2= 0.785= 79%
Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
