Roddy Richards invested​ $12014.88 in Wolverine Meat Distributors​ (W.M.D.) five years ago. The investment had yearly arithmetic
arlik [135]

Answer:

The arithmetic average return would be 3.96%

Step-by-step explanation:

Given,

The returns in 5 years are,

-​9.7%, -​8.1%, ​15%, 7.2%, and​ 15.4%

We know that,

\text{Arithmetic average}=\frac{\text{Sum of all observations}}{\text{Number of observations}}

Hence,

The arithmetic average return of the investment = \frac{-9.7-8.1+15+7.2+15.4}{5}

=\frac{19.8}{5}

= 3.96%

Is it possible to draw a triangle with sides 150cm, 10 cm, and 10cm
Oliga [24]
<span>It is absolutely impossible to draw a triangle of sides 150 , 10 and 10 cm. With one side so large, it is impossible, which will make the two angles two small to intersect and the angle will be < 0, which is not possible in a triangle.

If K is the midpoint of JL, JK = 8x + 11 and KL = 14x – 1, find JL.​
masha68 [24]

Answer:

JL=54

Step-by-step explanation:

We are given that K is the midpoint of JL. Using this information, we want to find JL.

By the definition of midpoint, this means that:

JK=KL

Substitute them for their equations:

8x+11=14x-1

Solve for <em>x.</em> Subtract 8<em>x</em> from both sides:

11=6x-1

Add 1 to both sides:

6x=12

And divide both sides by 6. Hence:

x=2

JL is the sum of JK and KL. Hence:

JK+KL=JL

Since JK = KL, substitute either one for the other:

JK+(JK)=2JK=JL

Substitute JK for its equation:

2(8x+11)=JL

Since we know that <em>x</em> = 2:

2(8(2)+11)=2(16+11)=2(27)=54=JL

Thus:

JL=54

Luke Skywalker mixes bantha milk that is 16% protein with tauntaun milk that is 9% protein. How many pounds of each should he mi
umka2103 [35]

<em>b</em> = amount of bantha milk

<em>t</em> = amount of tauntaun milk

<em>b</em> + <em>t</em> = 350

0.16 <em>b</em> + 0.09 <em>t</em> = 0.12(<em>b</em> + <em>t</em>) = 42

<em>t</em> = 350 - <em>b</em>

0.16 <em>b</em> + 0.09 (350 - <em>b</em>) = 42

0.16 <em>b</em> + 31.5 - 0.09 <em>b</em> = 42

0.07 <em>b</em> = 10.5

<em>b</em> = 150

<em>t</em> = 200

show that the relation R in R define as R = {(a, b): a&lt;_ b}, is reflexi when transistor but not symmetry​
kati45 [8]

Answer:

R is reflexive and transitive but not symmetric.

Step-by-step explanation:

R = {(a, b); a ≤ b}

Clearly (a, a) ∈ R as a = a.

R is reflexive.

Now,

(2, 4) ∈ R (as 2 < 4)

But, (4, 2) ∉ R as 4 is greater than 2.

R is not symmetric.

Now, let (a, b), (b, c) ∈ R.

Then,

a ≤ b and b ≤ c

→ a ≤ c

→ (a, c) ∈ R

R is transitive.

Thus, R is reflexive and transitive but not symmetric.
