Roger wishes to determine the average high

1 answer:

8 0

Roger's method would not provide relevant results for what he was trying to accomplish because he was calculating average over a 3 month period instead of for a single day.

<h3>How to find the mean temperature?</h3>

Mean/Average of any given data simply means the sum of the given data divided by the sample size of the given data.

Now, when talking about average temperature, it simply means adding the temperatures for the duration you intend to analyze and then dividing the sum by the number of temperatures you added.

However, in this question Roger wants to find the average temperature for any given data and we know the temperatures in a 24-hour day may differ from time to time and as such the mean/average for a particular day would simply be found by adding up temperatures for the day and then dividing by the number of temperatures added.

Thus, Roger's method would not provide relevant results for what he was trying to accomplish because he was calculating average over a 3 month period instead of for a single day.

What is the solution of log z + 12 = 9?<br> 1,000<br> -0.001<br> 0.001<br> -1.000<br> Done

zvonat [6]

Answer:

z =0.001

Step-by-step explanation:

log z + 12 = 9

Subtract 12 from each side

log z + 12-12 = 9-12

log z = -3

Raise each side to the base of 10

10^ log z = 10 ^-3

z = 10 ^-3

z =0.001

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. x2+3/2x

denis23 [38]

Answer:

The added term needed for that expression to be a square is 9/16.

Step-by-step explanation:

We're provided with two terms, and asked to add an additional term to make this a perfect square. For this to work, the term needs to be a scalar value that is the square of half the coefficient of the second term.

That coefficient is 3/2, so half of that is 3/4, and its square is 9/16.

If we tack that on the end then, we get:

$x^2 + \frac{3x}{2} + \frac{9}{16}\\=(x + \frac{3}{4})^2$

To confirm the answer, let's expand it and see if we get the original expression:

$(x + \frac{3}{4})^2\\= (x + \frac{3}{4})(x + \frac{3}{4})\\= x^1 + \frac{3x}{4} + \frac{3x}{4} + \frac{9}{16}\\= x^2 + \frac{6x}{4} + \frac{9}{16}\\=x^2 + \frac{3x}{2} + \frac{9}{16}$

So 9/16ths is the scalar that needs to be added on the end.

Combine like terms.

coldgirl [10]

Answer:

To solve the question the answer is 35y2 - 5 (i think)

Step-by-step explanation:

Yes and it's actually very simple.

To start off:

Simplify the equation: multiply 7 by the numbers in the parentheses getting: 28y2 - 35 .......full equation: 7y2 + (28y2 - 35)

New equation: 7y2 + (28y2 - 35) now combine like terms this means adding each common variable together. in this case, 7y2 and 28y2 would be added together to simplify the equation. Add them together, the new equation is: 35y2 - 5

Lmk if you have any questions i hope this helps
