Answer:

$m=\frac{-7}{5}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>:

$m=\frac{2-9}{11-6}$

$m=\frac{-7}{5}$

marin [14]

Answer:

The percent error in his estimate is<u> 16.67%</u>.

Step-by-step explanation:

Given:

Christopher estimates it will take him half an hour to complete his math homework.

He is able to complete it in 25 minutes.

Now, to find the percent error in his estimate.

Time estimates of completing homework = 30 minutes.

Time actual taken to complete homework = 25 minutes.

Error in estimate = Time estimates of completing homework - Time actual taken to complete homework.

Error in estimate = 30 minutes - 25 minutes.

Error in estimate = 5 minutes.

Now, to get the percent error:

$Percent\ error =\frac{Error\ in\ estimate}{Time\ estimates\ of\ completing\ homework} \times 100.$

$Percent\ error=\frac{5}{30} \times 100$

$Percent\ error=\frac{500}{30}$

$Percent\ error=16.67\%.$

Therefore, the percent error in his estimate is 16.67%.

If a = -4, b = 2, C = 3, and d = -5, then what is the value of (a - b)2 + (c- d)2

leva [86]

Answer:

100

Step-by-step explanation:

Put the values where the corresponding variables are, then do the arithmetic.

(-4 -2)^2 +(3 -(-5))^2

= (-6)^2 +(8)^2

= 36 +64 = 100

John wants to nail a thumbtack on his circular board, pictured below. If the thumbtack is equally likely to be placed anywhere o

Nikitich [7]

Answer: A. 51%

Step-by-step explanation:

Area of circle = $\pi r^2$ , where r = radius of the circle.

In the figure below, we have the complete question.

According to that,

Radius of outer circle = 7ft

Radius of inner circle = 5ft

The probability that the thumbtack will be placed on the inner circle

$=\dfrac{\text{Area of inner circle}}{\text{Area of outer circle}}\\\\=\dfrac{\pi (5)^2}{\pi (7)^2}\\\\=\dfrac{25}{49}$ [π is canceled from numerator and denominator

in percent, $\dfrac{25}{49}\times100=51.0204081633\%\approx51\%$

So, the probability that the thumbtack will be placed on the inner circle = 51%

Hence, the correct option is A. 51%.
