Answer: 1/2 or 0.5

Steps:

First, find the quotient.

• Remember when dividing the same bases with different exponents, you subtract the exponents and keep the base.

They both have a base of 2 so subtract the exponents.

2-3= -1

= 2^-1

Next, use properties of exponents to eliminate the negative exponent.

2^-1 = 1/2^1

= 1/2

The children in my subdivision were bored one summer and decided to hold a competition to see who could run to the end of the st
Ainat [17]

Answer:

6.7% of children who finished the race in under 45 seconds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 75 seconds

Standard Deviation, σ =  20 seconds

We are given that the distribution of time of completion is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(finished the race in under 45 seconds.)

P(x < 45)

P( x < 45) = P( z < \displaystyle\frac{45 - 75}{20}) = P(z < -1.5)

Calculation the value from standard normal z table, we have,  

P(x < 45) = 0.067 = 6.7\%

6.7% of children who finished the race in under 45 seconds.

I don't understand this :( pls help
svp [43]
Hello!

So, the slope is 2, which means "up 2 over 1" because of rise over run and 2 is 2/1.  

You have to find the graph that as a line passing through (-2, -3), so the answer is going to be Graph D. 

Hope this helps :))
