Answer:
aₙ = 4(5)ⁿ⁻¹
Explanation:
To identify a geometric series: second term = √(first term * third term)
Here given:
check ============
20 = √(100*4)
20 = √400
20 = 20 Hence its a geometric term.
Find common difference (r):
20/4 = <u>5</u> or 100/20 = <u>5</u>
Geometric term formula:
aₙ = a₁(r)ⁿ⁻¹ [where a1 is the 1st term, r is common difference]
<u>insert values found</u>
aₙ = 4(5)ⁿ⁻¹ ......this is the nth term.
Answer:
the current yield is 7.0%
Option a) 7.0% is the current answer
Step-by-step explanation:
Given that;
coupon payment = 7 1/4% = 7.25% = 0.0725
bond price = 103.375.
we know that
Current Yield = [ coupon payment / Bond prices ]
= [100 × 0.0725] / [ 103.375 ]
= 7.25 / 103.375
= 0.0701 or 7.0% {nearest tenth percent}
therefore the current yield is 7.0%
Option a) 7.0% is the current answer
Answer:
The probability of choosing bag 1 is 0,0412
Step-by-step explanation:
As the question emphasizes the probability of bag one, it is that we consider only this one. Bag 1 contains 10 blue marbles and 6 red marbles are added, in total 16 marbles. From this bag 1 extract 3 blue and 2 red marbles, without repetition. In probability it is expressed:
P (Bag₁) = 10/16 * * 9/15 * 8/14 * 6/13 * 5/12 = 0,0412
Answer:
$5.62 it could also possibly be $5.63 if you have to round up.
Step-by-step explanation:
Answer:
A) 1.5
B) x^2-23x+42 = (x-2)(x-21)
C) x=2, x=21
Step-by-step explanation:
a) 15 -2x / 3 = 4
15-2x = 12 (Times by three on both sides)
-2x = -3
x = -3/-2 = 3/2 = 1.5
b) x^2-23x+42
x^2-23x+42 = (x-2)(x-21)
c) x^2 -23x +42 = 0
x=2, x=21
(x-2) = 0 ⇒ x = 2
(x-21) = 0 ⇒ x = 21
