Hi there!
To write 3 x 3/8 as a unit fraction it is 9/8.
To write 3 x 3/8 as a whole number it is 1 1/8.
Explanation:
When you multiply 3 x 3/8 you get 9/8.
But when you make it to a proper fraction you get 1 1/8.
Hope this helps ;)
The probability of failure per time interval can we admit for a single switch is 25%.
The probability formula is described as the opportunity of an occasion to show up is equal to the ratio of the number of beneficial results and the total variety of consequences. probability of occasion to manifest P(E) = quantity of beneficial consequences/overall quantity of effects.
The chance of an event can be calculated by means of chance formulation by means of without a doubt dividing the favorable range of consequences through the whole range of possible effects.
Probability offers facts approximately the chance that something will appear. Meteorologists, as an example, use climate styles to predict the probability of rain. In epidemiology, the chance principle is used to recognize the relationship between exposures and the danger of health results.

The square root of 49 is 7. The square root of 121 is 11. 7-11 is -4, which is your answer.
Answer:
20 units²
Step-by-step explanation:
The x-intercepts are symmetrically located around the x-coordinate of the vertex, so are at
1.5 ± 5/2 = {-1, 4}
Using one of these we can find the unknown parameter "a" in the parabola's equation (in vertex form) ...
0 = a(4 -1.5)² +12.5
0 = 6.25a +12.5 . . . . . simplify
0 = a +2 . . . . . . . . . . . divide by 6.25
-2 = a
Then the standard-form equation of the parabola is ...
y = -2(x -1.5)² +12.5 = -2(x² -3x +2.25) +12.5
y = -2x² +6x +8
This tells us the y-intercept is 8. Then the relevant triangle has a base of 5 units and a height of 8. Its area is given by the formula ...
A = (1/2)bh = (1/2)(5)(8) = 20 . . . . units²
