The equation 3+7+2=+2 is actually not true, but false.

The equation 3+7+2=+2 is actually not true, but false. This is because the sum of 3, 7, and 2 is 12, not 2.

In general, an equation is considered true if the expressions on both sides of the equal sign are equivalent in value. In this case, the expressions on the left-hand side (3+7+2) and the right-hand side (+2) are not equivalent, and therefore the equation is false.

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

a. The coupon rate is 6%.

b. The current yield is 7.23%.

c. The approximate yield to maturity is 6.0372%.

d. The exact yield to maturity is 7.14%.

a. The coupon rate is the annual interest payment divided by the par value of the bond, expressed as a percentage.

Thus, the coupon rate is:

Coupon rate = (Annual interest payment / Par value) x 100%

Coupon rate = ($60 / $1,000) x 100%

Coupon rate = 6%

Therefore, the coupon rate is 6%.

b. The current yield is the annual interest payment divided by the market price of the bond, expressed as a percentage.

Thus, the current yield is:

Current yield = (Annual interest payment / Market price) x 100%

Current yield = ($60 / $830) x 100%

Current yield = 7.23%

Therefore, the current yield is 7.23%.

c-1. To find the approximate yield to maturity, we can use the approximation formula:

Approximate yield to maturity = Coupon rate + ((Par value - Market price) / ((Par value + Market price) / 2)) / (Years to maturity).

Using the given values, we have:

Approximate yield to maturity = 6% + ((($1,000 - $830) / (($1,000 + $830) / 2)) / 5)

Approximate yield to maturity = 6% + (170 / $915) / 5

Approximate yield to maturity = 6% + 0.0372

Approximate yield to maturity = 6.0372%

Therefore, the approximate yield to maturity is 6.0372%.

c-2. To find the exact yield to maturity, we need to solve for the yield rate in the following bond pricing equation:

Market price = (Coupon payment / Yield rate) x (1 - (1 + Yield rate)^(-n)) + (Par value / \((1 + Yield rate)^n)\)

where n is the number of years to maturity.

We can use trial and error or a financial calculator to find the yield rate that satisfies this equation.

Using a financial calculator, we enter the following values:

N = 5

I/Y = ?

PMT = $60

FV = $1,000

PV = -$830.

Then, we solve for the yield rate (I/Y) and find that it is 7.14%.

Therefore, the exact yield to maturity is 7.14%.

To find the kernel of the linear transformation T, we need to solve the equation T(x, y, z) = (0, 0, 0).

From the definition of T, we have:

T(x, y, z) = (0, 0, 0) if and only if

(0, 0, 0) = (0x + 0y + 0z, 0x + 0y + 0z, 0x + 0y + 0z)

This means that any vector (x, y, z) in R3 that satisfies 0x + 0y + 0z = 0 is in the kernel of T.

In other words, the kernel of T consists of all vectors of the form (x, y, z) where x, y, and z are any real numbers, since any such vector satisfies the equation 0x + 0y + 0z = 0.

Therefore, the kernel of T is the set of all vectors of the form (x, y, z) where x, y, and z are real numbers, which can be written as:

ker(T) = {(x, y, z) | x, y, z ∈ ℝ} = ℝ3.

So, the kernel of T is all real numbers (REALS).

The length of CD in the circle is 16 / 9 π units.

In the circle m∠CBD = 160 degrees. The area of the shaded sector is 16 / 9 π. The length of CD can be found as follows:

Therefore, let's find the radius,

area of sector = ∅ / 360 × πr²

where

Therefore,

area of sector = 160 / 360 × r²π

16 / 9 π = 160πr² / 360

cross multiply

5760π = 1440πr²

divide both sides by 1440π

r² = 4

r = √4

r = 2 units

Therefore,

length of CD = ∅ / 360 × 2 π × 2

length of CD = 160 / 360 × 4π

length of CD = 640 / 360 π = 160π / 90 = 16 / 9π

The amount of money Morgan will have after 3 years in the savings account is $315.60.

The formula to calculate the amount of money in a savings account after a certain number of years with compound interest is

A = P(1 + r/n)^(nt)

Where:

A = the amount of money in the account after the specified time period

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, Morgan invests $275 at an interest rate of 4% per year, compounded once a year, and keeps the money in the account for 3 years.

So, we can plug in the values into the formula

A = 275(1 + 0.04/1)³

A = 275(1 + 0.04)³

A = 275(1.04)³

A = $315.60

Let the first number be x and the second number be y. Then we have:

xy/4 = 10 + 9 + 10

Simplifying the right side:

xy/4 = 29

Multiplying both sides by 4:

xy = 116

Now we need to find two numbers whose product is 116. We can start by listing the factors of 116:

1, 2, 4, 29, 58, 116

Since we are looking for two numbers whose product is 116, we can try pairs of factors until we find a pair that works:

1 x 116 = 116 (not a sum of two numbers)

2 x 58 = 116 (sum is 60, not 19)

4 x 29 = 116 (sum is 33, not 19)

So the only pair that works is:

x = 29 and y = 4

Let's check if these values satisfy the original equation:

xy/4 = 29 x 4 / 4 = 29 = 10 + 9 + 10

So the solution is x = 29 and y = 4.

The best sample frame when studying the nature of product defects generated by two types of stamping machines is a D) list of all stamping machines in the factory, divided into two groups by type of machine.

When studying the nature of product defects generated by two types of stamping machines, the best sample frame is the list of all stamping machines in the factory divided into two groups by the type of machine. A sample frame refers to a list of items or individuals from which a sample is drawn.

The sample frame is an important element of a research study as it forms the basis for choosing the sample. It should be inclusive, accurate, and up-to-date. It is also critical to define the sampling unit and the population so that the correct sample frame can be selected.

The list of all machines in your factory would not be an appropriate sample frame because not all machines would be involved in the production of the stamped products.

A list of all serial numbers of stamping machine output during one month would not be suitable as the sample frame as it would be biased towards a specific time period and may not represent the entire population of the stamping machines in the factory.

None of the options listed above provide the best sample frame.

The length of radius AO, given that chord AB has a length of 32 cm and the distance from the center of the circle to chord AB is 9 cm, is approximately 15.6 cm.

In a circle, the radius perpendicular to a chord bisects the chord. Therefore, we can divide chord AB into two equal parts by drawing a line segment from the center of the circle, O, to the midpoint of AB.

Given that the length of chord AB is 32 cm, and the distance from the center of the circle to chord AB is 9 cm, we can use the Pythagorean theorem to find the length of radius AO.

Let's denote the midpoint of AB as point M. We have:

OM = 9 cm (distance from the center to the chord)

AB = 32 cm (length of the chord)

Using the Pythagorean theorem, we can calculate the length of radius AO:

AM^2 + OM^2 = AO^2

(16 cm)^2 + (9 cm)^2 = AO^2

256 cm^2 + 81 cm^2 = AO^2

337 cm^2 = AO^2

AO ≈ √337 ≈ 18.36 cm

It takes 6.75 years for the population to reach 50,400 organisms and value of a is 12000 and b=1.146.

We know that the initial population is 12,000, so we can substitute this into the equation:

12,000 = ab⁰

12,000 = a

Therefore, a = 12,000.

Next, we need to find the growth rate (b) per year.

The population grows by 14.6% each year, which can be expressed as 1 + 0.146 (decimal form). So, b = 1.146.

Now we have the values of a and b:

a = 12,000

b = 1.146

To determine the number of years until the population reaches 50,400 organisms.

we can substitute P = 50,400 into the exponential model and solve for t:

50,400 = 12,000 × 1.146^t

Taking the logarithm of both sides can help us solve for t:

log(50,400) = log(12,000 × 1.146^t)

Using logarithmic properties, we can simplify the equation:

log(50,400) = log(12,000) + log(1.146^t)

t = (log(50,400) - log(12,000)) / log(1.146)
