Replace y with 15

The equation is now:

1x - 15 = 30

Add 15 to both sides:

1x = 45

Divide both sides by 1

X = 45

Answer: X = 45

Step-by-step explanation:

1x - 15 = 30

add 15 to both sides

1x = 30 + 15

1x = 45

then you have to seperate the 1 from the x, so divide 1 from both sides

45 divided by 1 = 45

so the answer is x = 45

A stock has a beta of 1.30, the expected return on the market is 10 percent, and the risk-free rate is 4.6 percent. What must th
Ronch [10]

Answer:

11.62%

Step-by-step explanation:

Calculation for What must the expected return on this stock be

Using this formula

Expected return=Risk-free rate+(Expected market return -Risk-free rate)*Beta

Let plug in the formula

Expected return=4.6%+(10%-4.6%)*1.30

Expected return=4.6%+(5.4%*1.30)

Expected return=0.046+0.0702

Expected return=0.1162*100

Expected return=11.62%

Therefore What must the expected return on this stock is 11.62%

Determine if the conjecture is true or false. If true, explain your reasoning briefly. If false provide a counterexample.
Arisa [49]

9514 1404 393

Answer:

  false

Step-by-step explanation:

The conjecture shown in this problem statement does not follow from the examples offered. They support the notion that ...

  1/x ≤ x . . . . for x ≥ 0 (<u>not x ≤ 0</u>)

There are several possible counterexamples showing the conjecture is FALSE.

  1. 1/0 is undefined
  2. 1/(-5) > -5 . . . . . . . . a case for x < 0

If the intended domain is x ≥ 0, then the conjecture can also be demonstrated to be false for 0 < x < 1:

  1. 1/(1/5) > 1/5

Find the total surface area of this square based<br> pyramid.<br> 10ft<br> 10 ft<br> [? ]ft?
faltersainse [42]

Answer:

300 ft^{2}

Step-by-step explanation:

area of triangle= \frac{b*h}{2}

\frac{10*10}{2} = 50

4 sides of the triangle

4*50=200

area of square= l*w

10*10=100

area of square+area of triangles

200+100=300

_ft^{2}=300ft^{2}
