Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93
Answer:
Let b be the number of branches that the shrub will have after m months, since the shrub has an initial amount of 12 branches and the shrub grows 4 new branches every month, then we can set the following equation:
Evaluating the above equation at m=7 we get:
Simplifying the above result we get that the shrub will have
branches after 7 months.
Answer:
x =9 ,6
Step-by-step explanation:
With n tosses, there are a total of 2^n possible outcomes. We need 15 of theses to be heads.
Since the tosses are random, we want to count the ways to have exactly 15 of them being heads. That will be C(n,15) ways to pick which tosses are heads.
The probability will be given by:
C(n,15)/2^n=0.0148
At this point we use various values of n until we get the correct probability.
n=18⇒0.003112793
n=19⇒0.007392883
n=20⇒0.014785767
n=21⇒0.025875092
Answer:
n=20
In the mentioned plot line, Winners are of all ages from 29 Years old to 60 years. So, The answer would be: 29-60 Years.
The Information is useful for data collector, who holds the record of Statistics in order to find the progress or something in the numeral values.
Person under that age group, readers would benefit from it, 'cause former will get confidence and latter an useful information
