-2.105 as a fraction?

Bezzdna [24]

The easiest way is if it doesn't need to be simplified. Multiply -2.105 by $\frac{1000}{1000}$ . You get the fraction $-\frac{2105}{1000}$ . While this is technically the answer, you can simplify this down to $\frac{421}{200}$ . Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is $\frac{421}{200}$ .

$\frac{421}{200}$ .

Procedure

b = Number of balls

r = Number of rows

T = Total number of balls

b = r

$\begin{gathered} T=b\cdot r \\ Given\text{ b=r} \\ T=b^2 \\ b=\sqrt[]{T} \\ b=\sqrt[]{81} \\ b=9 \end{gathered}$

The answer is:

Suppose that the probability a seed will germinate is 85%. What is the probability that 7 of these seeds will germinate when 10

Viktor [21]

Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819

Required probability = 120 * 0.0010819 = 0.1298

2^8-10-15÷3<br><br> can you help me plzzzz

GenaCL600 [577]

Answer:

241

Step-by-step explanation:

Simplify the following:

2^8 - 10 - 15/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

2^8 - 10 + -5

2^8 = (2^4)^2 = ((2^2)^2)^2:

((2^2)^2)^2 - 10 - 5

2^2 = 4:

(4^2)^2 - 10 - 5

4^2 = 16:

16^2 - 10 - 5

× | 1 | 6

2 | 5 | 6:

256 - 10 - 5

256 - 10 - 5 = 256 - (10 + 5):

256 - (10 + 5)

10 + 5 = 15:

256 - 15
