Explain how to divide an amount by number 3
Greeley [361]

Answer:

Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.

For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.

4*3=12

Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.

Hope this helps!

Simplify the expression by using a double-angle formula. 2 sin 31°cos 31°
qwelly [4]

The double angle formula for the sine is

\sin(2x) = 2\sin(x)\cos(x)

The right hand side is exactly your expression, where x = 31^\circ

So, rewriting the expression from right to left, we have

2\sin(31^\circ)\cos(31^\circ) = \sin(2\cdot 31^\circ) = \sin(61^\circ)

svp [43]

Answer:

0.2839 = 28.93%

Step-by-step explanation:

In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z

Le x be tons of coal in a car

Z = (x – mean)/standard deviation

Z = (x – μ)/ σ

P (x<68.5) = P(z < (68.5-69)/0.9)

P (x<68.5) = P(z < -0.5555)

Then we use the z table to find the area under the curve.

P (x<68.5) = 0.2893
