A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number greater than 2
Leona [35]
There is a 2/3 probability. Why? Well, the cube is numbered 1-6 so that is 6 numbers. Out of 6, there are 4 numbers greater than 2. Because of this, there is a 4/6 probability that a number greater than 2 will be rolled. 4/6 reduces to 2/3. As a percentage and decimal, the probability would be 66.66666666% or 0.66666666666 (repeating).

F(x) = -2x^5 + x^4 + x^2 -2; find f(-3) and f(4)
Alekssandra [29.7K]

Answer:

f(-3) = 574

f(4) = -1778

Step-by-step explanation:

f(x) = -2x^5 + x^4 + x^2 -2

f(-3) = -2(-3)^5 + (-3)^4 + (-3)^2 -2

\implies f(-3) = -2(-243) + 81 + 9 -2

\implies f(-3) = 486 + 81 + 9 -2

\implies f(-3) = 574

f(4) = -2(4)^5 + (4)^4 + (4)^2 -2

\implies f(4) = -2(1024) + 256 + 16 -2

\implies f(4) = -2048 + 256 + 16 -2

\implies f(4) =-1778

Lacey deposited $4,860 in a new credit union savings account on the first day of the quarter. The principal earns 4% interest co
Softa [21]

Answer:

$4956.23 approx

Step-by-step explanation:

Given data

P= $4860

R= 4%

T= 6 months = 0.5 years

Applying the compound interest formula we have

A=P(1+r)^t

Substitute

A=4860(1+0.04)^0.5

A= 4860(1.04)^0.5

A=4860*1.0198

A=4956.228

Hence the balance will be $4956.23 approx
