A set of average city temperatures in July are normally distributed
Archy [21]

Answer:

a) 59.87%

Step-by-step explanation:

Given that the mean temperature (μ) = 23.5°C and the standard deviation (σ) is 2 °C.

The z score is used in statistics to measure number of standard deviation by which the raw score is above or below the mean value, It is calculated using the equation:

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

The average temperature of the City of Van Nuys is 23 degrees. The z score is

z=\frac{x-\mu}{\sigma}=\frac{23-23,5}{2} =-0.25

P(x > 23) = P(z > -0.25) = 1 - P(z < -0.25) = 1 - 0.4013 = 0.5987 = 59.87%

Which expression is not equivalent to the other three?
AVprozaik [17]

Answer:

<em>4 + 7x – 2</em>

Step-by-step explanation:

<u>Equivalent Expressions</u>

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

2x + 2+ 2x + 3x -8=7x-6

Now for the second expression

4 + 7x -2=7x+2

The third expression simplifies to

-2 + 5x + 2x - 4=7x-6

Finally, this is the simplification for the expression

8x - x - 6=7x-6

As seen, the only expression not equivalent to the other three is 4 + 7x – 2

If the cost is a function depending in the number of sections, how much will 200 sections cost?
julsineya [31]
I would say the answer is D. 7837. Since the common ratio between the x’s and y’s were are 39.5 so multiplying that times 200 gives something around 7900 so, (rounding down) the answer would be D. I really hope that helped! Also please correct me if I am wrong... thanks!
