Answer:

$103

Step-by-step explanation:

Your living room is carpeted but you have allergies, and need to cover the 9 points floor with hardwood panel flooring. The panel flooring at Lowes cost $3.19 per square foot. (scale: 1m = 3.28 ft) Hint: Each unit contains 32.29 square feet. How much will it cost to purchase the flooring panels? (round to the nearest cent)

From the above question:

1 square foot = $3.19

32.29 square feet = x

Cross Mulitiply

x = 32.29 × $3.19

x = $103.0051

Approximately to the nearest cent = $103

Therefore, it will cost $103 to purchase the flooring panels

Answer:

1.963%

Step-by-step explanation:

Use the equation for compound interest

\(A = P(1 + \frac{r}{n})^{nt}\)

\(5400 = 4800(1 + \frac{r}{365})^{(365)(6)}\\5400/4800 = 4800(1 + \frac{r}{365})^{(365)(6)}/4800\\1.125 = (1 + \frac{r}{365})^{2190}\\\sqrt[2190]{1.125} = \sqrt[2190]{ (1 + \frac{r}{365})^{2190}} \\1.0000537836544 = 1 + \frac{r}{365} \\1.0000537836544 -1 = 1 + \frac{r}{365} -1\\.0000537836544 = \frac{r}{365}\\(.0000537836544)(365) = ( \frac{r}{365})(365)\\.019631 = r\)

Let be the subset of consisting of all vectors such that and determine if is a subspace of and check the correct answer(s) below. a. is a subpace because it has a zero element. Option (A)

Let \($S$\) be the subset of \($\mathbb{R}^3$\) consisting of all vectors such that \(x_1 + x_2 + x_3 = 0$.\) To determine if $S$ is a subspace of \($\mathbb{R}^3$\), we need to check the following three conditions:

\($S$\) contains the zero vector\(: $(0,0,0) \in S$ since $0+0+0=0$.\)

$S$ is closed under addition: if\($\mathbf{u}, \mathbf{v} \in S$,\)then \($(u_1+v_1)+(u_2+v_2)+(u_3+v_3) = (u_1+u_2+u_3) + (v_1+v_2+v_3) = 0+0 = 0$, so $\mathbf{u}+\mathbf{v} \in S$.\)

$S$ is closed under scalar multiplication: if\($\mathbf{u} \in S$ and $c$ is\) a scalar, then \(c\mathbf{u} = c(u_1,u_2,u_3) = (cu_1,cu_2,cu_3)$ and $(cu_1+cu_2+cu_3) = c(u_1+u_2+u_3) = c\cdot0 = 0$, so $c\mathbf{u} \in S$.\)

Since all three conditions are satisfied, we conclude that \($S$\) is a subspace of\($\mathbb{R}^3$.\)Therefore, the correct answer is (a) is a subspace because it has a zero element.

A significance level of 5% (more commonly referred to as 95%) corresponds to a statement that (only) a probability of 5% or less is that a particular randomly generated observation is accepted as significant.

In this example, the p-level (the true probability that the observations are randomly generated) is less than 5% (0.0421 <0.05), so we can draw the conclusion that the observations are significant.

p = 0.0421 means that the probability is only 0421/1000. The choice of significance level to reject the null hypothesis is optional. Traditionally, 5%, 1%, and 0.1% levels have been used. In rare situations, a 10% significance level is also used.

Step-by-step explanation:

A midwife delivers 10 babies, with 50% chance of delivering a boy and 50% of delivering a girl. The probability that 6 out of 10 babies will be boys is 20.5%

The problem can be solved using binomial distribution, that is the probability of 2 possible outcomes in a number of trials.

The formula is given by:

P(x) = ⁿCx . P^x . (1 - P)^(n-x)

x = total number of event A

n = number of trials

P = probability of A in a single trial

Parameters given in the problem:

n = 10

x = 6

P = 50% = 0.5

Plug these parameters into the formula:

P(6 boys) = ¹⁰C₆ . (0.5)⁶ .  (0.5)⁴

                = 0.205 = 20.5%

Hence, the probability that 6 out of 10 babies will be boys is 20.5%

The SSS(Side-Side-Side) Triangle congruency is proven by following rule.

In SSS (Side-Side-Side) condition the two triangles are said to be congruent if the three sides of one triangle are equivalent to the corresponding three sides of the second triangle.

In mathematics, the term "congruent" refers to figures and shapes that can be flipped or rearranged to match up with other ones. These forms can be mirrored to produce related shapes. A triangle is a closed polygon with three line segments that intersect at each of its three angles.

Two shapes are congruent if their sizes and forms are comparable. Additionally, if two shapes are congruent, then their mirror images are likewise congruent.

Distance-Rate-Time and other Products

In this lesson, we will investigate the relationship between the distance traveled, the rate or speed or travel, and the time that it takes to travel that distance at that rate. We will also look at a few other related products.

Distance = (Rate)(Time)

The equation that relates distance, rate, and time is

d = rt

Where d is the distance traveled, r is the rate, and t is the time. On the CAHSEE exam, you will be given two of these and will be asked to use the above equation to find the third.

Example 1

It took Markus half an hour to drive home from work. He averaged 34 miles per hour. How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip. This is a time:

t = 1/2

We are given that he averages 34 miles per hour. This is a rate:

r = 34

We are asked how few he has traveled. This is a distance. We use the d=rt equation:

d = rt

= (34)(1/2)

= 17

Markus lives 17 miles from work.

Now try one by yourself. If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Exercise 1

The current along the beach is moving towards the south at 1.5 miles per hour. If a piece of debris is placed into the water, how far will the current take it in 6 hours?

9 miles

Example 2

Elena always rides her bicycle at a speed of 15 miles per hour. On Sunday, she goes on a 24 mile bike ride. How many hours does this ride take?

Solution

The speed of 15 miles per hour is a rate. The key words that tell us that this is a rate are "speed" and "miles per hour". We can write:

r = 15

Next, 24 miles is a distance. We have:

d = 24

Now use the d=rt equation to get

24 = 15t

To solve this, divide both sides by 15 to get

t = 24/15

Both are divisible by 3, so this fraction reduces to

t = 8/5 = 1.6

Elena's ride takes 1.6 hours.

Step-by-step explanation:

The Pythagorean Theorem is stated as follows: The square of the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides. a and b represent the legs of the right triangle.

What is the basic requirement to apply Pythagoras theorem?

Since both triangles' sides are the same lengths a, b and c, the triangles are congruent and must have the same angles. Therefore, the angle between the side of lengths a and b in the original triangle is a right angle. The above proof of the converse makes use of the Pythagorean theorem itself.

The total net pay for the week is $433.Answer: $433 .

Rheanna Boggs, an interior fabricator for a large design firm, pays $45 for medical insurance, $21 for union dues, and $10 for a stock option plan weekly. Her gross pay is $525 and she claims one allowance. So, we need to calculate the total net pay for the week. For this, we need to calculate the total amount of deductions that Rheanna Boggs has to make.

Deductions can be calculated as shown below:$45 + $21 + $10 = $76Total deductions made by Rheanna Boggs = $76Now, we can calculate the taxable income. For this, we need to use Table 2.3. As Rheanna Boggs is single and claims one allowance, we will use the row for "Single" and column for "1" to find the value of withholding allowance.

Taxable income = Gross pay − Deductions − Withholding allowance= $525 − $76 − $77 = $372Now, we can calculate the federal tax. For this, we need to use Table 2.4. As the taxable income is $372 and the number of allowances is 1, we can use the row for "$370 to $374" and column for "1".Federal tax = $16Now, we can calculate the total net pay for the week. This can be calculated as shown below:Total net pay = Gross pay − Deductions − Federal tax= $525 − $76 − $16 = $433Therefore, the total net pay for the week is $433.Answer: $433 .

The general solution of the given homogeneous differential equation is:y = ±x√(Cx² + 2)

The given differential equation is: 2xyy' + (x² - y²) = 0

We have to find the general solution of the given homogeneous differential equation. To solve the above differential equation, we will use the substitution method.

Put y = vx and y' = v + xv'

Differentiating both sides w.r.t x: y' = v + xv' ⇒ v' = (y' - v)/x

Differentiating again w.r.t x: y'' = v' + xv'' + v' ⇒ y'' = (y'' - 2y'v + v² + xv')/x

Substituting these values in the given differential equation:

2x(v)(v + xv') + (x² - v²x²) = 0

2v + 2x²v' + x - v² = 0

2x²v' + 2v/x - v³/x = -1/x

We can write the above differential equation as:

2x²dv/dx + 2v/x = v³/x - 1/x

Separating the variables and integrating both sides:

∫dx/x = ∫[v/(v² - 2)]dv/x

⇒ ln |x| + ln |v² - 2| + C

⇒ ln |x(v² - 2)| = ln |Cx|

⇒ v² - 2 = Cx² (where C is a constant)

⇒ v = ±√(Cx² + 2)

Putting the value of v in y = vx, we get:

y = x√(Cx² + 2) and y = -x√(Cx² + 2)
