Given that the area of a 15° secant has an area of 11.9 m2, then the area of the circle will be given by:
(Total measure in degrees of the circle)/(measure in degrees of the secant)*(area of secant)
=360/15*11.9
=24*11.9
=285.6 m^2
Answer: 285.6 m^2
Answer:
- <u>There are six pairs in the sample space.</u>
Explanation:
The only question shown is <em>a) Determine the number of sample points in the sample space.</em>
The box contains three cards. They are each marked. The representations of the marks are the letters Q, P and M. Thus, the cards are marked:
- one with a Q,
- other with a P, and
- other with an M.
Two cards are to be selected at random with replacement. Thus, the possibilities are:
First card, second card
Q P
Q M
P Q
P M
M Q
M P
Therefore, the sample space contains 6 pairs (points): QP, QM, PQ, PM, MQ, MP.
First you reduce the fraction
3 6/20 = 3 3/10
Now you do the fractional division 3/10 = 3 ÷ 10 = .3

Answer:
139 ( D )
Step-by-step explanation:
Interest rate on loan = 4% = 0.04
Number of payments = 15
First 10 payments = 100 each
last 5 payments = 200 each
Calculating the value of K
K = [ ( 100 / 0.04 * ( 1-1 / 1.04^10 ) + 200/0.04 * ( 1-1 / (1 +0.04)^5)* 1 /1.04^10)
* 1.1 - 100 / 0.04 * ( 1-1 / (1+0.04)^5 ) - 200/0.04 * (1-1 /1.04^5) * 1/1.04^10)*0.04 / ( 1-1 / 1.04^5) * (1 + 0.04)^5
= 138.6051 ≈ 139
3.4+2(9.7-4.8x)=61.2
3.4+19.4-9.6x=61.2
22.8-9.6x=61.2
-9.6x=61.2+22.8
-9.6x=84
9.6x=-84
x=-84÷9.6
x=-8.75
