A $1,000.00 bond at 85 1/4 % pays 6.8 % annual interest. Calculate cost of bond.

stepladder [879]

Based on the par value of the bond and the percentage it was issued at, the cost of the bond is $852.50.

The current cost of the bond is the present value of the bond's cashflows and its par value.

This is taken into account when the bond is issued at a certain percentage which in this case is 85 ¹/₄%.

The cost of the bond is:

= 1,000 x 85 ¹/₄%

= $852.50

The number of defective units in a production run of 850 circuit boards are normally distributed with 21 defective units and 3 d

Katen [24]

Answer:

82%

Step-by-step explanation:

We let the random variable X denote the number of defective units in the production run. Therefore, X is normally distributed with a mean of 21 defective units and a standard deviation of 3 defective units.

We are required to find the probability, P(17 < X < 25), that the number of defective units in the production run is between 17 and 25.

This can be carried out easily in stat-crunch;

In stat crunch, click Stat then Calculators and select Normal

In the pop-up window that appears click Between

Input the value of the mean as 21 and that of the standard deviation as 3

Then input the values 17 and 25

click compute

Stat-Crunch returns a probability of approximately 82%

What is the area of the trapezoid?

MA_775_DIABLO [31]

Area of Trapezoid

$A = \dfrac{(B + b)h}{2}$

where B = larger base, b = smaller base, and h = height.

For this trapezoid, you have
B = 10 + 7 + 7 = 24
b = 10
h = 9

$A = \dfrac{(24 + 10) \times 9}{2}$

$A = 153$

Let A = {n ℤ | n = 5r for some integer r} and B = {m ℤ | m = 20s for some integer s}. Determine which of the following statement

Assoli18 [71]

Answer:

Incomplete question

This is the complete aspect of the question

a. Is this true or false

A⊆B?

b. Is this true or false

B⊆A?

Step-by-step explanation:

Given that

A = {n ℤ | n = 5r for some integer r}

Integer are positive and negative whole numbers

A={...-20,-15,-10,-5,0,5,10,15,20...}

Also,

B ={mℤ |m = 20s for some integer s}.

Then,

B={....-80,-40,-20,0,20,40,80....}

a. In mathematics, a set A is contained in B if every element in A is found in B

Then,

A⊆B

Then looking at A and B, not all element in A can be found in B e.g, 10, 15,25,-10,-25 and so, the law doesn't hold

Then, A⊆B is false

b. B⊆A, now every element in B can be found in A, then this is true and then B is contain in A
