14(6x - 3) = 99(22)

<u>Distribute 14 and 99:</u>

84x - 42 = 2178

<u>Add 42 to both side:</u>

84x = 2220

<u>Divide both sides by 84:</u>

x = 26 3/7

Answer: x = 26 3/7

First you'd need to multiply 99 by 22.

14 ( 6x - 3 ) = 99 × 22

14 ( 6x - 3 ) = 2,178

Next, you'd divide both sides by 14.

14 ( 6x - 3 ) = 2,178

\displaystyle\frac{14(6x-3)}{14} = \frac{2,178}{14}

\displaystyle\ 6x - 3 = \frac{2,178}{14}

Now simplify 2,178 over 14.

\displaystyle\ 6x - 3 = \frac{2,178}{14}

\displaystyle\ 6x - 3 = \frac{1,089}{7}

Now add 3 to both sides to get rid of -3.

\displaystyle\ 6x - 3 = \frac{1,089}{7}

\displaystyle\ 6x - 3 + 3= \frac{1,089}{7} + 3

\displaystyle\ 6x = \frac{1,110}{7}

Now divide both sides by 6 to get x alone.

\displaystyle\ 6x = \frac{1,110}{7}

\displaystyle\frac{6x}{6} = \frac{\frac{1,110}{7}}{6}

\displaystyle\ x  = \frac{185}{7}

Now we simplify.

\displaystyle\ x  = \frac{185}{7}

\displaystyle\ x = 26\frac{3}{7}

in one region, the September energy consumption levels for single-family homes are found to be normally distributed with a mean
VARVARA [1.3K]

Answer:

a=1050 -0.126*218=1022.53

So the value of height that separates the bottom 45% of data from the top 55% is 1022.53.  

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the energy consumption of a population, and for this case we know the distribution for X is given by:

X \sim N(1050,218)  

Where \mu=1050 and \sigma=218

For this part we want to find a value a, such that we satisfy this condition:

P(X>a)=0.55   (a)

P(X   (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.45 of the area on the left and 0.55 of the area on the right it's z=-0.126. On this case P(Z<-0.126)=0.45 and P(z>-0.126)=0.55

If we use condition (b) from previous we have this:

P(X  

P(z

But we know which value of z satisfy the previous equation so then we can do this:

z=-0.126

And if we solve for a we got

a=1050 -0.126*218=1022.53

So the value of height that separates the bottom 45% of data from the top 55% is 1022.53.

$ 570 2% 4years simple interest
denis-greek [22]
For simple interest, just multiply all of them together

note that 2% = 0.02

570(0.02)(4) = 45.6

simple interest is 45.6

oh and if you need the equation, it is p(r)t, or principle x rate x time

hope this helps
