Answer:
A and B
Step-by-step explanation:
The measures of 2 vertical angles are always equal, so we have:
7x+182=9x+192.
Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.
Thus, x=-6.
This means that the angles are:
i) 7x+182=7(-6)+182=182-42= 140(degrees).
ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)
Answer: x=-6</span>
Answer:
d
Step-by-step explanation:
The correct answer is (D). If X is the number of tickets thrown away, then this is a binomial setting with n = 15 and p = 0.01.
Then P(X = 1) = 15C1 (0.01)1(0.99)14 = 15(0.01)1(0.99)14.
Answer:
amount = 407 per month
Step-by-step explanation:
given data
future value = $5000
interest rate = 6% = = 0.015
time = 12 months = 4 compound per year
solution
we use here formula that is
amount = future value × .......................1
put here value and we get
amount = 5000 ×
amount = 1222 per quarter
or amount = 407 per month
