Answer: x=5, choice D
Step-by-step explanation:
you have two vertical angles
11x=55
55/11=5
x=5
Answer:
Correct statement: (a) and (b).
Step-by-step explanation:
R-squared is a statistical quantity that measures, just how near the values are to the fitted regression line. It is also known as the coefficient of determination.
The coefficient of determination is the squared value of the correlation coefficient.
That is,
The correlation coefficient between two variables is the measure of the strength and direction of the relationship between two variables.
Its values ranges from -1.00 to +1.00.
Although <em>r</em> can be negative but R² is always positive, since square of a negative number is also positive.
So the correct statements are:
a. cannot be negative
b. is the square root of the coefficient of correlation
Answer: D. multiplication

In order to find the slope, we may use the formula:
Slope = (y2−y1)/(x2-x1)
Now, let's identify the values. Say, point <em>a</em><em> </em>is the first point and <em>b</em><em> </em>is the second. This means that:
x1 = 3
y1 = 2
x2 = 7
y2 = 10
Let's plug in the values:
=(10-2)/(7-3)
=8/4
=2
Now, to determine if the slope is downward or upward, <u>p</u><u>o</u><u>s</u><u>i</u><u>t</u><u>i</u><u>v</u><u>e</u><u> </u><u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>m</u><u>e</u><u>a</u><u>n</u><u>s</u><u> </u><u>u</u><u>p</u><u>w</u><u>a</u><u>r</u><u>d</u><u> </u><u>f</u><u>r</u><u>o</u><u>m</u><u> </u><u>l</u><u>e</u><u>f</u><u>t</u><u> </u><u>t</u><u>o</u><u> </u><u>r</u><u>i</u><u>g</u><u>h</u><u>t</u> while <u>n</u><u>e</u><u>g</u><u>a</u><u>t</u><u>i</u><u>v</u><u>e</u><u> </u><u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>m</u><u>e</u><u>a</u><u>n</u><u>s</u><u> </u><u>d</u><u>o</u><u>w</u><u>n</u><u>w</u><u>a</u><u>r</u><u>d</u><u> </u><u>f</u><u>r</u><u>o</u><u>m</u><u> </u><u>l</u><u>e</u><u>f</u><u>t</u><u> </u><u>t</u><u>o</u><u> </u><u>r</u><u>i</u><u>g</u><u>h</u><u>t</u>.
So since our slope is positive 2, it is upward.
FINAL ANSWER:
Slope = 2
It slopes upward from left to right.
