2(x + 4) − 1 = 2x + 7
Margarita [4]

Answer:

All real numbers are solutions to this problem.

Step-by-step explanation:

I) Simplify:

2(x + 4) - 1 = 2x + 7

x + 4 - 0.5 = x + 3.5 (Divide by 2)

x + 3.5 = x + 3.5 (Simplify <em>x + 4 - 0.5</em>)

x = x

II) Conclusion:

Any real number will work as a solution.

Mandy has an IQ of 115. We know that the mean () IQ is 100 with a standard deviation of 15. There are 100 people in Mandy’s Alc
Alex787 [66]

Answer: 16

Step-by-step explanation:

Given : Mean : \mu=100

Standard deviation : \sigma =15

The value of z-score is given by :-

z=\dfrac{x-\mu}{\sigma}

For x= 115

z=\dfrac{115-100}{15}=1

The p-value : P(z>1)=1-P(z

Now, the number of people smarter than Many is given by :_

100\times0.1586553=15.86553\approx16

Hence, there are 16 members smarter than Mandy.

Eight car dealerships reported the number of cars they sold last month.
Temka [501]

Answer:

Step-by-step explanation:

You'll need to share the set of data if you want a precise answer.

But here's how to find the IQR:

1.  Arrange the data in ascending (increasing) order

2.  Identify the median.   This divides the list of data into two parts.

3.  Find Q1 and Q3.  They are the medians of these two parts.

4   Subtract Q1 from Q3.  The result is the IQR that you wanted.
