Help me with this problem !!!!!!!!!!
Mamont248 [21]

Answer:

Hi, your answer is y=-\frac{1}{2} x-3

Step-by-step explanation:

We will use the slope-intercept formula which is

\frac{y2-y1}{x2-x1}

We will use two points in this case I'll use

(-2,-2) and (-8,1)

\frac{1-(-2)}{-8-(-2)}=-\frac{3}{6} which can be simplified as -\frac{1}{2}

Your Y will be -3

which your final answer will be y=-1/2x-3

Hope this helps :)

Suppose on a certain test, fifty students earn a perfect score and fifty students earn a zero. determine the mean grade and stan
kodGreya [7K]

Answer:

Mean=50.

standard deviation=50.

Step-by-step explanation:

Let the perfect score be 100.

The mean(average) of a data is given by: Mean=\frac{sum of data points}{number of data points}

Here the number of data points are 100. out of which 50 attains a value 100,and 50 attains value 0.

so, sum of data points=50×100+50×0=5000.

Mean=\frac{5000}{100}

Mean=50.

"Now the standard deviation of data points are calculated by firstly subtracting mean from every entry and then square the number and take it as new entry and calculate the mean of the new data entry and lastly taking the square root of this new mean".

Here if 50 is subtracted from each entry the new entry will have 50 entries as '50' and 50 entries as '-50'.

next on squaring we will have all the 100 entries as '2500'.

now the mean of these entries is: \frac{2500\times100}{100}

                                                         =2500

taking it's squareroot we have \sqrt{2500}=50

Hence, standard deviation=50.

malfutka [58]
∠ABC is an inscribed angle.
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc.  m∠ABC = 48°  ⇒
measure of arc AC = 2*m∠ABC = 2 * 48 = 96°.
