Step-by-step explanation:
If (from the image attached) DE is a line segment that divides the sides AB and AC proportionally in ΔABC then we can prove that line segment DE is parallel to BC using the parallel transversal theorem. Based the parallel transversal theorem, the triangles ABC and ADE are similar therefore angles are congruent and line DE must be parallel to line BC
simplify this algebraic expression completely 5y - 3(y+2)
Answer: 2y - 6
Step-by-step explanation:
This problem utilizes the Distributive Property of Multiplication. It states that: a(x + y) = ax + ay.
Thus, utilizing this property (distributing -3), change the equation into:
5y - 3y - 6
Then, simply combine like terms to get:
2y - 6

Write an equation in slope-intercept form for the line perpendicular to y=2x−3 that passes
through the point (−3,−3).
Answer:
y = -1/2x - 9/2
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 2x - 3. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.
Plug this value (-1/2) into your standard point-slope equation of y = mx + b.
y = -1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, -3). Plug in the x and y values into the x and y of the standard equation.
-3 = -1/2(-3) + b
To find b, multiply the slope and the input of x (-3)
-3 = 3/2 + b
Now, subtract 3/2 from both sides to isolate b.
-3 - 3/2 = b
-6/2 - 3/2 = b
-9/2 = b
Plug this into your standard equation.
y = -1/2x - 9/2
This equation is perpendicular to your given equation (y = 2x - 3) and contains point (-3, -3)
Hope this helps!

A man earns N 5,000.00 for 10
days work. How should he earn in
14 days, if working at the same
rate
Answer:
N 7,000.00
Step-by-step explanation:
He earns N 5,000.00 for 10 days of work so divide the 5,000.00 by 10
5,000.00/10= 500.00 ; this is the amount of money he makes in 1 day
Then multiply this amount make in 1 day by 14 to find how much the man makes in 14 days.
500.00*14=7,000.00
Therefore, the man makes N 7,000.00 in 14 days.

Answer:
A. y = 3x
Step-by-step explanation:
A proportional relationship is described by an equation of the form ...
y = kx
The equation of answer choice A is in that form with k=3. It describes the relationship as proportional.
__
Answer choice B gives a single point on the position versus time graph. There is nothing to indicate it is part of a proportional relation.
Answer choice C tells you the relationship between time and distance (speed) is not constant. That assures you the relationship is NOT proportional.
Answer choice D does not tell you that the time starts counting when the turtle starts at the rock. It tells you the relation is linear, but does not tell you the relation is proportional.

In a certain town, 40% of adults have a college degree. If four adults from the town are
selected at random, the probabilities that 0, 1, 2, 3, or 4 of them will have college degrees are
provided in the accompanying table. Find the standard deviation for the probability
distribution
Х P(x)
0 0.1296
1 0.3456
2 0.3456
3 0.1536
4 0.0256
According to the discrete distribution given, the standard deviation is of: 0.98.
The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability, hence:
[tex]E(X) = 0.1296(0) + 0.3456(1) + 0.3456(2) + 0.1536(3) + 0.0256(4) = 1.6[/tex]
The standard deviation is the square root of the sum of the multiplication of each probability and the difference squared between the observation and the mean, hence:
[tex]\sqrt{V(X)} = \sqrt{0.1296(0-1.6)^2 + \cdots + 0.1536(3-1.6)^2 + 0.0256(4-1.6)^2} = 0.98[/tex]
The standard deviation is of 0.98.

Answer:
$5,336
Step-by-step explanation:
The formula for an ordinary annuity is ...
A = P((1 +r)^t -1)/r
We want to find P when A=70000, r=0.059, t=10
P = Ar/((1 +r)^t -1) = 70000(0.059)/(1.059^10 -1) ≈ 5336
Owen must contribute $5,336 each year for 10 years to have $70,000.
_____
Additional comment
If this is an annuity due, with contributions made at the beginning of the year, the above contribution amount can be divided by 1.059. That will give $5038 as the contribution amount.

A committee including 2 boys and 2 girls is to be formed from a group of 6 boys and 5 girls. How many different committee can be formed from the group
Step-by-step explanation:
well, we need to multiply the possibilities of forming a group of 2 boys out of 6 with the possibilities to firm a group of 2 girls out of 5.
the first is 6 over 2
6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15
the second one is 5 over 2
5! / (2! × (5-2)!) = 5×4/2 = 5×2 = 10
so, these 15 possibilities combined with the 10 possibilities makes
15×10 = 150
possibilities to form this committee.
