Answer:
y + 4 = ⅕(x + 7)
Step-by-step explanation:
The "point-slope" form of the equation of a straight line is:
y − y₁ = m(x − x₁)
where m is the slope and (x₁, y₁) is a point on the line.
If m = ⅕ and (x₁, y₁) = (-7, - 4), the point-slope equation is
y + 4 = ⅕(x + 7)
The Figure below shows the graph of your line and a point at (-7, -4).
Perpendicular sides or lines meet at right angles. The conclusion that can be reached is that:
<em>1. all of the rings are perpendicular to that side.</em>
The statements in the question can be listed as:
- <em>Rings in the ladder are parallel</em>
- <em>Top ring is perpendicular to the side of the ladder</em>
<em />
From statements 1 and 2 above, we understand that;
<em>All other rings in the ladder are parallel to the side ring</em>
This means that the relationship between the top ring and the side of the ladder is the same as the relationship between other rings and the side of the ladder
i.e. the side rings are also perpendicular to the side of the ladder
Hence, the conclusion that can be reached is:
<em>1. all of the rings are perpendicular to that side.</em>

Answer:
Step-by-step explanation:
Answer:
A, C are true . B is not true.
Step-by-step explanation:
Mean of a discrete random variable can be interpreted as the average outcome if the experiment is repeated many times. Expected value or average of the distribution is analogous to mean of the distribution.
The mean can be found using summation from nothing to nothing x times Upper P (x) , i.e ∑x•P(x).
Example : If two outcomes 100 & 50 occur with probabilities 0.5 each. Expected value (Average) (Mean) : ∑x•P(x) = (0.5)(100) + (0.5)(50) = 50 + 25 = 75
The mean may not be a possible value of the random variable.
Example : Mean of possible no.s on a die = ( 1 + 2 + 3 + 4 + 5 + 6 ) / 6 = 21/6 = 3.5, which is not a possible value of the random variable 'no. on a die'
