Answer:

6.25%

Step-by-step explanation:

To know the final probability that this has happened, we must multiply the probability of each event, they tell us that the probability that it is a girl is 1/2 and this happened 4 times, therefore:

(1/2) ^ 4 = 0.0625

that is, the probability that 4 girls are born is 6.25%

an unusual probability is considered when it is less than 5%, therefore, although it approaches this figure, it is not unusual

PLEASE HELP ASAP DUE IN 3 MINUTES

Inga [223]

Answer:

1728 in²

Step-by-step explanation:

For the area of B, you need to find the length and width (height and base, whatever you want to call it).

For the height, you would need to do: 144 - 36 - 24 - 36 = 48 inches

For the base, you would need to do: 60 - 24 = 36 inches

Now you multiply the base and height to get the area: 48 x 36 = 1728 in²

Work out the value of 2. 4510 ×10to the power of 9 1.15 × 10 to the power of 3

Simora [160]

Answer:

The result in standard form is: $2.3 \times 10^{6}$

Step-by-step explanation:

Dividing the values:

To find the real part, we divide 2.645 by 1.15. So

2.645/1.15 = 2.3

Finding the power:

Its a division, so we keep the base, and subtract the exponents. So

$\frac{10^9}{10^3} = 10^{9-3} = 10^{6}$

Result in standard form:

The result in standard form is: $2.3 \times 10^{6}$

If the present value of an item is P

Mumz [18]

Answer:

$50,000

Step-by-step explanation:

Formula to find interest :

I = Prt

Solving :

I = (20,000)(0.06)(25)
I = (1.5)(20,000)
I = (30,000)

Future value :

P + I
20,000 + 30,000
$50,000
