Based on the hypothesis test using a significance level (α) of 0.05 and a p-value of 0.20, we fail to reject the null hypothesis, which suggests that we should not build a brick-and-mortar store.

In hypothesis testing, we compare the p-value to the significance level (α) to make a decision about the null hypothesis (H0). The null hypothesis states that there is no significant effect or relationship, while the alternative hypothesis (Ha) suggests otherwise.

In this case, the null hypothesis (H0) states that we should not build a brick-and-mortar store, and the alternative hypothesis (Ha) suggests that we should build one. When the p-value is higher than the significance level (α), it means that we do not have enough evidence to reject the null hypothesis.

Given that the p-value is 0.20 and the significance level (α) is 0.05, the p-value is greater than α. Therefore, we fail to reject the null hypothesis, indicating that there is not enough evidence to support building a brick-and-mortar store. This means that based on the statistical analysis, it would be recommended not to proceed with constructing a physical store.

Since triangles abc and xyz are similar, their corresponding sides are proportional.

Let's label the sides of triangle xyz as a, b, and c. We know that the smallest side of xyz (side a) is 52 cm. We need to find the length of the longest side of xyz (which we can label as side c).
We can set up a proportion to solve for c:  121/52 = 105/b = 98/c
Solving for b, we get:  121/52 = 105/b
b = (105*52)/121
b ≈ 45.6
Now we can set up a new proportion to solve for c:  121/52 = 98/c
Multiplying both sides by c, we get:  121c/52 = 98
Solving for c, we get:
c = (98*52)/121
c ≈ 42.3
Therefore, the length of the longest side of xyz is approximately 42.3 cm.

Answer:

A

Step-by-step explanation:

Recall that sin = opposite over hypotenuse

For ∠A we are already given its opposite side length ( 2 ) however the hypotenuse has not been identified.

The triangle shown is a right triangle ( indicated by the little square on the bottom left ) which means that we can find a missing side length, more specifically the hypotenuse, using the Pythagorean theorem

\(a^2+b^2=c^2\) where a and b = legs and c = hypotenuse

we are given that the legs = 2 and 4 and need to find the hypotenuse

That being said we plug in what we are given and solve for c

\(2^2+4^2=c^2\\2^2=4\\4^2=16\\16+4=20\\20=c^2\)

In order to get the exact value of c we must get rid of the exponent.

To do so we can take the square root of both sides

\(\sqrt{20} =\sqrt{20} \\\sqrt{c^2} =c\\c=\sqrt{20}\)

hence, the hypotenuse = √20

Now lets look back at the question

Find sin∠A to the nearest hundredth.

well remember sin = opposite over hypotenuse

The opposite of sin∠A is 2 and the hypotenuse is √20

Hence, sin∠A = \(\frac{2}{\sqrt{20} }\) which is equivalent to .447213595

Our last step is to round to the nearest hundredth

We get the sin∠A = .45

Answer:

x = 7

Step-by-step explanation:

A median bisects the opposite side length, therefore

14x = 6x+56

8x = 56,

x = 7

Answer:

x = 7

Step-by-step explanation:

given:

AM is the median

BM = 14x

MC = 6x + 5x

since the median is drawn fron vertex A to BC it bisects the BC into two equal halves. So,

14x = 6x + 54

14x - 6x = 54

8x = 54

x = 54/8

The probability distribution of the number of hours per day people are able to relax is constructed, and probabilities of relaxing more than 4 hours, between 2 to 6 hours, and not relaxing at all are 0.283, 0.767 and 0.068 respectively. The mean and standard deviation are 3.326 hours and 1.950 hours (approx.) respectively.

The probability distribution of X is:

8 60                    0.036

      1676                     1.000

The probability that a person relaxes more than 4 hours per day is:

P(X > 4) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)

= 0.138 + 0.089 + 0.020 + 0.036

= 0.283

The probability that a person relaxes from 2 to 6 hours per day is:

P(2 ≤ X ≤ 6) = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

= 0.201 + 0.150 + 0.189 + 0.138 + 0.089

= 0.767

The probability that a person does not relax at all is:

P(X = 0) = 0.068

The mean Mx is:

Mx = Σ(X * P(X))

= 00.068 + 10.093 + 20.201 + 30.150 + 40.189 + 50.138 + 60.089 + 70.020 + 8*0.036

= 3.326 hours

The standard deviation Ox is:

Ox = sqrt[Σ(X^2 * P(X)) - Mx^2]

= sqrt[(0^20.068)+(1^20.093)+(2^20.201)+(3^20.150)+(4^20.189)+(5^20.138)+(6^20.089)+(7^20.020)+(8^2*0.036) - 3.326^2]

Length of the shorter diagonal of the parallelogram will be 18.46 feet

Let the Parallelogram ABCD with BD and AC as it’s diagonal

According to the question,

AB = 17 feet

AD = 11 feet

As the opposite sides of a parallelogram are parallel and equal

Therefore, AB = CD = 17 feet

                AD = BC = 11 feet

Also the longer diagonal, BD = 22 feet

In triangle BCD, using cosine formula

\(BD^{2}\) = \(CD^{2}\) + \(BC^{2}\)- 2BC.CD.CosC

\(22^{2}\) = \(17^{2}\) + \(11^{2}\) - 2(11)(17)Cos C

484 = 289 + 121 - 374CosC

-0.197 = Cos C

C = arc Cos(-0.197)

Therefore, C = \(110^{0}\)

Now ∠C + ∠D = \(180^{0}\)

101+  ∠D = 180

∠D = \(79^{0}\)

Now, in triangle ADC

\(AC^{2}\) = \(AD^{2}\) + \(CD^{2}\) - 2AD.CD.CosD

 \(AC^{2}\) = \(11^{2}\) + \(17^{2}\) - 2(11)(17)Cos79

\(AC^{2}\) = 121 + 289 - 374Cos79

\(AC^{2}\) = 410 -364(.19)

\(AC^{2}\) = 340.84

AC = sqrt(340.84)

AC = 18.46

Answer:

On average, the number of breakdowns per day varies from the mean by about 0.28.

Step-by-step explanation:

the distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ.

What is Equivalence relation?

An equivalence relation is a relation between elements of a set that satisfies three properties: reflexivity, symmetry, and transitivity.

a) To prove that R is an equivalence relation, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any integer m, we need to show that m R m, i.e., 4 |\((m^2 - m^2).\) Since the difference of squares is 0, which is divisible by 4, the relation is reflexive.

Symmetry: For any integers m and n, if m R n, then we need to show that n R m. If 4 | \((m^2 - n^2)\), then \((m^2 - n^2)\) is divisible by 4. Taking the negative of both sides, we have\((-n^2 + m^2) = (m^2 - n^2)\), which is also divisible by 4. Therefore, n R m, and the relation is symmetric.

Transitivity: For any integers m, n, and p, if m R n and n R p, then we need to show that m R p. Suppose 4 |\((m^2 - n^2)\)and 4 \(| (n^2 - p^2)\). This means \((m^2 - n^2) and (n^2 - p^2)\)are both divisible by 4. Adding these two divisibility statements, we get (m^2 - p^2) is also divisible by 4, which implies m R p. Hence, the relation is transitive.

Since the relation R satisfies reflexivity, symmetry, and transitivity, it is an equivalence relation.

b) The distinct equivalence classes of the relation R can be described by the set of all integers that are congruent modulo 4. In other words, each equivalence class contains integers that have the same remainder when divided by 4.

The distinct equivalence classes can be denoted as follows:

[0] = {..., -8, -4, 0, 4, 8, ...}

[1] = {..., -7, -3, 1, 5, 9, ...}

[2] = {..., -6, -2, 2, 6, 10, ...}

[3] = {..., -5, -1, 3, 7, 11, ...}

Each equivalence class consists of integers that satisfy the condition 4 | (m^2 - n^2), and within each class, any two integers have their squares yielding the same remainder when divided by 4.

c) The distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ. A partition of a set is a collection of non-empty, pairwise disjoint subsets whose union is the entire set.

In this case, the equivalence classes [0], [1], [2], and [3] are non-empty and pairwise disjoint because no integer can simultaneously belong to two different equivalence classes. Also, the union of all the equivalence classes covers the entire set of integers, as each integer belongs to exactly one of the equivalence classes.

Therefore, the distinct equivalence classes [0], [1], [2], and [3] form a partition of ℤ.

Given:

Total amount spend on movie = $75

Each friend bought a ticket and a small popcorn that cost $8.25.

To find:

The price of each ticket.

Solution:

Let x be the price of each ticket.

Total cost of ticket and popcorn of each friend \(=x+8.25\)

Total cost of ticket and popcorn of three friend \(=3(x+8.25)\)

It is given that, the total amount spend on movie is $75. So,

\(3(x+8.25)=75\)

\(x+8.25=\dfrac{75}{3}\)

\(x+8.25=25\)

Subtract 8.25 from both sides.

\(x=25-8.25\)

\(x=16.75\)

Therefore, the cost of each movie ticket is $16.75.

The product of powers rule states that when you multiply two powers with the same base, you can add the exponents. For example, 23 · 25 = 28 because 2+3=5 and 5+3=8.
In the expression 34 · 28, the bases are different. 34 means 3 raised to the power of 4, and 28 means 2 raised to the power of 8. Since the bases are not the same, you cannot simplify the expression using the product of powers rule.

Step-by-step explanation:

The radius of the circle will be \(\sqrt{22}\).

In our question, we shall first extend QRS to the circle's point T.

According to the power of a point.

\(QP^{2}\)  =  QR*QT

\(6^{2}\)  =  3*QT

QT = 12

Since QR = 3, RT = 9.

Since RS = 3, ST = 6.

Draw OT and OR, creating a triangle(TSO) and triangle(RSO).

OT and OR are radii, Let the radius be r.

Use the Law of Cosines on these two triangles.

OT2  =  \(r^{2}\)  =  \(6^{2}\) + \(2^{2}\) - 2*6*2*cos(TSO)

OR2  =  r2  =  \(3^{2}\) + \(2^{2}\) - 2*3*2*cos(RSO)

Since these are equal:

\(6^{2}\) + \(2^{2}\) - 2*6*2*cos(TSO)  =  \(3^{2}\) + \(2^{2}\) - 2*3*2*cos(RSO)

40 - 24*cos(TSO)  =  13 - 12*cos(RSO)

Since angle(RSO) is supplementary to angle(TSO),  cos(RSO) = - cos(TSO)

40 - 24*cos(TSO)  =  13 + 12*cos(TSO)

27  =  36*cos(TSO)

0.75  =  cos(TSO)

Since  \(OT^{2}\)  =  \(r^{2}\)  =  \(6^{2}\) + \(2^{2}\) - 2*6*2*cos(TSO)

\(r^{2}\)  =  40 - 24*0.75  

\(r^{2}\)  =  22

r  =  \(\sqrt{22}\)
