A=h(b+c)
A/h=b+c
b=(A/h)-c
Answer: b=(A/h)-c
Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
Answer:

Step-by-step explanation:
the upper quartile = 8
What do you need help with? it helps us to know the question!
The expirmental probability us 28/50
Theoreticaly the probability is 25/50 because that would be half :)
