(88r+33)-2(-9+6r)
(88r+33) + (18-12r)
88r+33+ 18- 12r
76r + 51
This is the concept of probability and statistics, the z-score associated by the probability of 25% will be obtained using the z-tables, and hence we shall have:
P(x)=25=0.25
thus checking the z-score that gives us the probability of 0.25 we get:
-0.67
the answer is z=-0.67
Answer:
The Cardboard dimensions are 13cm in length and 12cm in breadth
Step-by-step explanation:
We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)
Answer:
0.0333
Step-by-step explanation:
(image is missing)
Let's assume that the entire are in the distribution curve is 1
Given
Time taken from 0s to 30s = 30s - 0s = 30s
To find height of the distribution?
Let H = the height of the distribution
Based on the above assumption;.
H * 30 = 1 --- make H the subject of formula
H = 1/30
H = 0.0333
Hence, the calculated height of the distribution is 0.0333
Your answer is 98
This is because. u (18) + xy (10 × 8 = 80) so
18 + 80 = 98
Hope this helped
