Answer:

$4.32

Step-by-step explanation:

8% can be represented as 1.08

2 x 1.08 = 2.16

2 x 1.08 x 1.08 = 2.33

2 x 1.08 x 1.08 x 1.08 = 2.52

etc. all the way up to 10

Answer:

$1,065.71

Step-by-step explanation:

use the compound interest formula: A = P(1 + r/n)^nt where:

P = principal, $2

r = interest rate, 8% = .08

t = term, in years; 10

n = # of times per year compounding occurs; 1

A = 2(1 + .08/10)^10(1)

A = 2(1 + .008)^10

A = 2(1.008)^10

A = 2.008^10

A = 1065.71

Answer:

Step-by-step explanation:

coordinate of O(2,1),Y(3,-2),T(-3,-3)

let the reflected points are O',Y',T'

distance of O from y=2 is 1 unit.

∴ ordinate of O' =1+2(1)=3

or O' is (2,3)

distance of Y from y=2 is2+2=4

ordinate of Y'=-2+2(4)=6

so coordinate of Y' is (3,6)

distance of T from y=2 is (2+3)=5

so ordinate of T' =-3+2(5)=7

coordinate of T' is(-3,7)

An event is three times as likely as its complement. What is the probability of the event?

serg [7]

E = some event
C = complement of event E
Since the events are complementary, this means P(E)+P(C) = 1

We know that P(E) = 3*P(C) since "an event is three times as likely as its complement"

So we can replace P(E) with 3*P(C) and then isolate P(C)
P(E) + P(C) = 1
3*P(C) + P(C) = 1
4*P(C) = 1
P(C) = 1/4

The probability of the complementary event is 1/4
So the probability of the original event is 3/4 (three times 1/4)

Answer: 3/4

note: in decimal form, 3/4 = 0.75

2. In a recent survey conducted by the International Nanny Association, 4,176 nannies were placed in a job in a given year. Only

Natali [406]

Answer:

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

Desired outcomes:

The number of male nannies selected. 24 of the nannies placed were men. So the number of desired outcomes is 24.

Total outcomes:

The number of nannies selected. 4,176 nannies were placed in a job in a given year. So the number of total outcomes 4176.

Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

$P = \frac{24}{4176} = 0.0057$

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").
