Answer:

There is a positive correlation between the number of hours spent on homework and the test scores. So, the more homework you do, the better your test score.

Step-by-step explanation:

The data given is representative of a scatter plot, which shows a relationship with two sets of data that, when using a line of best fit, will show either a positive correlation (increasing), a negative correlation (decreasing) or no correlation (the data shows no overall pattern). In this case, you can see that the overall pattern of data is increasing, or a positive correlation. Which means that, in general, the more hours of homework you do, the more likely you are to receive a better test score.

If 10% of x is 30, what is 23% of x <br> A. 33<br> B. 46<br> C. 200<br> D. 230

Answer:

Step-by-step explanation:

I'm mathematics, the word 'of' transfers into becoming 'times or Multiply'

Therefore, the expression can be rewritten as:

10/100 of x = 30

10x / 100 = 30

Cross Multiply the equation to solve for x

10x = 100 * 30

10x = 3000

x = 3000 / 10

x = 300

(Since we gotten the value of x as 300) let's find 23% of it.

Therefore,

23% of x, ( when x is 300)

= 23/100 * 300

= 23 * 3

= 69

(Well, although that's the workable solution, the option doesn't seen to tally)

Maybe you check the source, but am certain about the Solution.

What did sin theta/theta whisper worksheet answer key worksheet?

djyliett [7]

To evaluate
$\lim_{\theta \to 0} \frac{\sin\theta}{\theta}$

First, we input 0, for theta in the function to obtain:
$\frac{\sin0}{0} = \frac{0}{0}$

This is an indeterminate form.

So, we apply L'Hopital's rule by differentiating the numerator and the denominator as follows:

$\lim_{\theta \to 0} \frac{\sin\theta}{\theta}=\lim_{\theta \to 0} \frac{ \frac{d}{d\theta} (\sin\theta)}{\frac{d}{d\theta}\theta} \\ \\ =\lim_{\theta \to 0} \frac{\cos\theta}{1}=\cos0=1$

Answer:

82.96

Step-by-step explanation:

area of box:

A = L^2 = (14 in.)^2 = 196 in.^2

area of pizza:

A = (pi)r^2 = 3.14 * (6 in.)^2 = 113.04 in.^2

Empty area:

196 in.^2 - 113.04 in.^2 = 82.96 in.^2

Find the slope of the line that passes through the points E(-1, 3) and F(-2, -3)

Nesterboy [21]

Answer=6

Formula for slope:

$slope= \frac{y _{2}-y _{1} }{x _{2}-x _{1} }= \frac{-3-3}{-2-(-1)} = \frac{-6}{-1}=6$
