Remember you can do anything to an equation as long as you do it to boht sides


8-8m=8m+56
add 8m to both sides
8+8m-8m=8m+8m+56
8+0=16m+56
8=16m+56
minus 56 both sides
-48=16m
divide both sides by 16
-3=m

Additive property of equality states that:

if a=b, then a+c = b+c, 

that is, if 2 quantities of the same value are added the same quantity, they are again equal.


In our problem a=AD, b=DB,    and c= CD=DE

thus a+c=b+c means <span>AD + CD = DE + DE, 

by the </span><span>Addition Property


Answer: </span><span>Addition Property

Iq scores are normally distributed with a mean of 100 and a standard deviation of 15 if one person is randomly selected what is
beks73 [17]

probability that the persons IQ falls between 110 and 130 is 0.2286 .

<u>Step-by-step explanation:</u>

Step 1: Sketch the curve.

The probability that 110<X<130 is equal to the blue area under the curve.

Step 2:

Since μ=100 and σ=15 we have:

P ( 110 < X < 130 )=P ( 110−100 < X−μ < 130−100 )

⇒ P ( (110−100)/15< (X−μ)/σ<(130−100)/15)

Since Z = (x−μ)/σ , (110−100)/15 = 0.67 and (130−100)/15 = 2  we have:

P ( 110<X<130 ) = P ( 0.67<Z<2 )

Step 3: Use the standard normal table to conclude that:

P ( 0.67<Z<2 )=0.2286

Therefore, probability that the persons IQ falls between 110 and 130 is 0.2286 .

The volume of a sphere can be calculated by V = 4/3 * pi If the volume is 113.04 cm ^ 3 what is the radius?
lisov135 [29]

Answer:

2.99 cm

Step-by-step explanation:

V= \frac{4}{3}(pi)(r^3)=113.04cm^3

113.04/ \frac{4}{3}(pi) = r^3 = 26.99

r=\sqrt[3]{26.99} = 2.99cm
