Answer:

Step-by-step explanation:

If you don't consider how the wood might be cut, or how the tray might be assembled, you can look only at the area requirements.

A tray that is 10.5 inches square will have an area of ...

  (10.5 in)^2 = 110.25 in^2

That base will have a perimeter that is 4×10.5 in = 42 in. If the perimeter piece(s) are 2 inches high, the area of the sides of the tray will be ...

  (42 in)(2 in) = 84 in^2

Then the total area of wood required for the proposed tray is ...

  110.25 in^2 +84 in^2 = 194.25 in^2

__

The area of the wood Stephan has is ...

  A = LW = (18 in)(12 in) = 216 in^2 . . . . . . more than required

__

Stephan does have enough wood to make the tray, because he has 216 square inches, which is more than he needs to make the tray, 194.25 square inches.

Answer:

Step-by-step explanation:

To prove that [tex]w_1,\dots w_n[/tex] form a basis for W, we must check that this set is a set of linearly independent vector and it generates the whole space W. We are given that T is an isomorphism. That is, T is injective and surjective. A linear transformation is injective if and only if it maps the zero of the domain vector space to the codomain's zero and that is the only vector that is mapped to 0. Also, a linear transformation is surjective if for every vector w in W there exists v in V such that T(v) =w

Recall that the set [tex]w_1,\dots w_n[/tex] is linearly independent if and only if  the equation

[tex]\lambda_1w_1+\dots \lambda_n w_n=0[/tex] implies that

[tex]\lambda_1 = \cdots = \lambda_n[/tex].

Recall that [tex]w_i = T(v_i)[/tex] for i=1,...,n. Consider [tex]T^{-1}[/tex] to be the inverse transformation of T. Consider the equation

[tex]\lambda_1w_1+\dots \lambda_n w_n=0[/tex]

If we apply [tex]T^{-1}[/tex] to this equation, then, we get

[tex] T^{-1}(\lambda_1w_1+\dots \lambda_n w_n) =T^{-1}(0) = 0[/tex]

Since T is linear, its inverse is also linear, hence

[tex]T^{-1}(\lambda_1w_1+\dots \lambda_n w_n) = \lambda_1T^{-1}(w_1)+\dots +  \lambda_nT^{-1}(w_n)=0[/tex]

which is equivalent to the equation

[tex]\lambda_1v_1+\dots +  \lambda_nv_n =0[/tex]

Since [tex]v_1,\dots,v_n[/tex] are linearly independt, this implies that [tex]\lambda_1=\dots \lambda_n =0[/tex], so the set [tex]\{w_1, \dots, w_n\}[/tex] is linearly independent.

Now, we will prove that this set generates W. To do so, let w be a vector in W. We must prove that there exist [tex]a_1, \dots a_n[/tex] such that

[tex] w = a_1w_1+\dots+a_nw_n[/tex]

Since T is surjective, there exists a vector v in V such that T(v) = w. Since [tex]v_1,\dots, v_n[/tex] is a basis of v, there exist [tex]a_1,\dots a_n[/tex], such that

[tex]a_1v_1+\dots a_nv_n=v[/tex]

Then, applying T on both sides, we have that

[tex]T(a_1v_1+\dots a_nv_n)=a_1T(v_1)+\dots a_n T(v_n) = a_1w_1+\dots a_n w_n= T(v) =w[/tex]

which proves that [tex]w_1,\dots w_n[/tex] generate the whole space W. Hence, the set [tex]\{w_1, \dots, w_n\}[/tex] is a basis of W.

Consider the linear transformation [tex]T:\mathbb{R}^2\to \mathbb{R}^2[/tex], given by T(x,y) = T(x,0). This transformations fails to be injective, since T(1,2) = T(1,3) = (1,0). Consider the base of [tex]\mathbb{R}^2[/tex] given by (1,0), (0,1). We have that T(1,0) = (1,0), T(0,1) = (0,0). This set is not linearly independent, and hence cannot be a base of [tex]\mathbb{R}^2[/tex]

Step-by-step explanation:

From trigonometry;

Tan87.4 =height of monument / 25

Height of monument = 25 * Tan 87.4

= 25 * 1.525

=38.125 ft

There is an extra substention of 5ft we add that

38.125 + 5 = 43.125 ft

I did the test, good luck! :)

Phil would need to save for at least 6 weeks to have enough money to buy the bike.

Phil saves one-quarter of his pay each week, which is:

1/4 x £240 = £60

Let's assume it takes him n weeks to save enough to buy the bike. Then, the amount he saves in n weeks is:

n x £60 = £349

We can solve for n by dividing both sides by £60:

n = £349 / £60

n ≈ 5.82

Since we can't have a fraction of a week, Phil would need to save for 6 weeks to have enough money to buy the bike.

Answer:

0.04

Step-by-step explanation:

Standard deviations== square root of variance define as spread.

Standard deviations square = variance

[0.2]^2= 0.04

Answer:

[tex] Range =1.41-0.66 = 0.75[/tex]

[tex] \bar X = 1.171 W/Kg[/tex]

[tex] s^2 = 0.0607[/tex]

And taking the square root we got the sample deviation:

[tex] s = \sqrt{0.0607}= 0.246 W/kg[/tex]

Step-by-step explanation:

For this case we have the following datset given:

0.83 1.39 1.39 1.03 0.66 1.26 1.39 1.18 1.41 1.19 1.15

We need to find the range, and the range is defined by:

[tex] Range = Max -Min[/tex]

And replacinng we got:

[tex] Range =1.41-0.66 = 0.75[/tex]

Then we can find the sample variance, but firt we need to find the sample mean with this formula:

[tex]\bar X = \frac{\sum_{i=1}^n X_i}{n}[/tex]

And replacing we got:

[tex] \bar X = 1.171 W/Kg[/tex]

Now we can find the sample variance with this formula:

[tex] s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}[/tex]

And replacing we got:

[tex] s^2 = 0.0607[/tex]

And taking the square root we got the sample deviation:

[tex] s = \sqrt{0.0607}= 0.246 W/kg[/tex]

Answer:

Mean, Median

Step-by-step explanation:

Outliers affect the mean because it is not resistant to outliers. They will affect the sum and therefore the mean.

The solution is, Mean, Median.

i.e. The outlier of a data set causes the Mean (mean/median) to be greater than the Median (mean/median) when the outlier is in the upper part of the data set.

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

we know that,

Outliers affect the mean because it is not resistant to outliers.

They will affect the sum and therefore the mean.

so, we get,

The outlier of a data set causes the Mean (mean/median) to be greater than the Median (mean/median) when the outlier is in the upper part of the data set.

hence, The solution is, Mean, and, Median.

Let v = 315π,

Let h = 21,

[tex]315\pi = \pi {r}^{2} \times 21[/tex]

Answer:

y = x/60

Step-by-step explanation:

y = kx

k = y / x = 10/600 = 1/60

y = x/60

[tex]y[/tex] is directly proportional to [tex]x[/tex] when [tex]x=600[/tex] and [tex]y=10[/tex] then the formula for [tex]y[/tex] in terms of [tex]x[/tex] is given  as  [tex]y=\frac{1}{60} x[/tex] .

We say that, [tex]y[/tex] and [tex]x[/tex] are directly proportional, if  [tex]\frac{y}{x} =k[/tex]  or [tex]y=kx[/tex].

So,

According to the question;

[tex]x=600[/tex]

[tex]y=10[/tex]

From the above statement;

[tex]\frac{10}{600} =k[/tex]

[tex]k = \frac{1}{60}[/tex] ,

So,

[tex]y[/tex] in terms of [tex]x[/tex] is given by,

[tex]y=\frac{1}{60} x[/tex]

Hence, we can say that [tex]y[/tex] is directly proportional to [tex]x[/tex] when [tex]x=600[/tex] and [tex]y=10[/tex] then the formula for [tex]y[/tex] in terms of [tex]x[/tex] is given  as  [tex]y=\frac{1}{60} x[/tex] .
