On March 20, 2011, a $1,000 bond had a selling price of $987.50. What was the quoted price for the bond?

Leviafan [203]

Answer:

98.75%.

Step-by-step explanation:

On March 20, 2011, a $1000 bond had a selling price of $987.50.

We are asked what will be the quoted price for the bond.

Now, the quoted price of a bond is the price at which the bond was last traded and it is expressed as the percentage of the original bond value.

So, in our case the quoted price will be $\frac{987.50}{1000} \times 100 = 98.75$ %. (Answer)

Can u help me solve for x in this equation please?

Usimov [2.4K]

To solve for x means to put x on one side, and everything else on the other side.

Let's do that:

$-ax+4b\ \textgreater \ 9$

$-ax \ \textgreater \ 9-4b$
And now we have to divide with -a.
Be careful: When dividing with anything that's negative, you have to reverse the inequality.
$x \ \textless \ \frac{9-4b}{-a}$

Final solution:
$x \ \textless \ \frac{4b-9}{a}$

6c + 14 = -5c + 4 + 9c c=

agasfer [191]

First combine like terms
6c + 14 = 4c + 4, then subtract 4c from both sides
2c + 14 = 4, then subtract 14 from both sides
2c = -10, then divide both sides by 2

C = -5

Roll a number cube. If the number cube comes up odd, you win the same number of points as the number on the cube. If the number

laila [671]

Answer:

–0.5

Step-by-step explanation:

Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.

The odd rolls are 1, 3 and 5. The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.

The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.

The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.

Rolling any even number gives us the same value. The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.

Together we have

1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5

At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 fr

podryga [215]

Answer:

An equation in the slope-intercept form will be:

y = 15x+210

Step-by-step explanation:

We know The slope-intercept form of the line equation

$y = mx+b$

where

m is the rate of change or slope

b is the y-intercept

Let x represent the time in months

Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

Thus, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

So, we take the point (3, 255)

substituting m = 15, x = 3 and y = 255 in the slope-intercept form to determine the y-intercept

y = mx+b

255 = 15(3) + b

switch sides

15(3) + b = 255

45 + b = 255

b = 255 - 45

b = 210

Now, substituting m = 15 and b = 210 in the slope-intercept form of the line equation

y = mx+b

y = 15x+210

Therefore, an equation in the slope-intercept form will be:

y = 15x+210
