Step-by-step explanation:

Answer:

Sweater: $26

Shirt: $5

Step-by-step explanation:

We can set up two linear equations to form a systems of equations which will allow us to solve for the price of a shirt and sweater.

The first step we want to take is assigning the shirt and sweater to an unknown, so I'll just refer to the price of a shirt as: [tex]S_h[/tex] with the little subscript "h" and I'll refer to the price of a sweater as: [tex]S_w[/tex] with the little subscript "w".

Now the next main thing to understand is we can calculate the total price of something by multiplying the price of an individual item by the quantity. So if I buy an apple for $10, but I buy 10 of them, then the total price would be 10 * 10 or $100. So when Andrea buys 6 shirts, the price of that can be represented as: [tex]6S_h[/tex] and when Anrea buys 7 sweaters the price of that can be represented as: [tex]7S_w[/tex], adding these together should equal 212, since it gives us that buying 6 shirts and 7 sweaters costs a total of $212.

Using this logic with the other case where she buys 10 shirts and 8 sweaters for $258, we can set up the two equations:

[tex]6S_h + 7S_w=212\\10S_h+8S_w=258[/tex]

From here we can use substitution to solve this equation. So let's solve for the [tex]S_h[/tex] on the top equation.

[tex]6S_h+7S_w=212[/tex]

Froom here subtract [tex]7S_w[/tex] from both sides and then divide by 6

[tex]S_h=\frac{212-7S_w}{6}[/tex]

Now we can plug this into the second equation:

[tex]10(\frac{212-7S_w}{6})+8S_2=258[/tex]

Simplifying the division and multiplication on the left side we get:

[tex]\frac{1060}{3}-\frac{70}{6}S_w+8S_w=258[/tex]

From here we can combine the like terms

[tex]\frac{1060}{3}-\frac{22}{6}S_w=258[/tex]

we can simplify the fraction a bit more

[tex]\frac{1060}{3}-\frac{11}{3}S_w=258[/tex]

Now subtract 1060/3 from both sides

[tex]\frac{-11}{3}S_w=\frac{-286}{3}[/tex]

Now divide both sides by -11/3

[tex]S_w=26[/tex]

Now from here we can substitute this back into any equation to solve for the shirt price. Let's use the equation where we solved for the price of the shirt but we just needed to know the price of the sweater.

[tex]S_h=\frac{212-7S_w}{6}[/tex]

Now let's plug in 26 for the sweater price.

[tex]S_h=\frac{212-7(26)}{6}[/tex]

Simplify this and we get:

[tex]S_h=5[/tex]

and now we know the shirt and sweater price!

The cost of car in the year 1983 is 2845

An equation is an expression that shows the relationship between two or more numbers and variables.

The CPI (consumer price index) is a measure of the overall change in prices of goods and services over a certain period of time. It is given by:

CPI = (cost of market basket in a given year / cost of market basket in base year) * 100

Given that:

CPI = 56.9 in 1976, cost of market basket in a given year = x, cost of market basket in base year = $5000

Hence:

56.9 = (x/ 5000) * 100

x = 2845

Answer:

14ft

Step-by-step explanation:

Perimeter of a square = 4s where s = side length

Here, we are given the perimeter, and we want to find the side length. To do so we plug in the perimeter and solve for s

Perimeter = 56

So 56 = 4s

==> divide both sides by 4

14 = s

A square with a perimeter of 56 feet has a side length of 14 feet

The equation cos (60°) = a/12 can be used to find one of the missing side lengths in the triangle.

Trigonometric identities are equations that are true for all values of the angles in a right triangle. They express the relationships between the angles and sides of a triangle and are used to simplify trigonometric expressions or to prove that two expressions are equal.

One of the trigonometric identities is the SOH CAH TOA.

SOH: sin θ = opposite/hypotenuse

CAH: cos θ = adjacent/hypotenuse

TOA: tan θ = opposite/adjacent

Since angle CBA is 60°, the adjacent side is a, the opposite side is b, and the hypotenuse is 12 units, then:

cos θ = adjacent/hypotenuse

cos (60°) = a/12

Rearranging the equation, we can solve one of the missing side lengths, which is a.

a = 12cos(60°)

Hence, we can use the equation cos (60°) = a/12 to find the length of side a.

The claim that the average of a random sample is the same as the average of the population from which it was taken is False.

The sample mean will, of course, differ from the population means. The sample mean, however, is a fair estimation of the population mean if the sample is a simple random sample.

Thus, neither the sample mean nor the population mean is statistically greater or lower. The sample mean will always have a mean that is identical to the mean of the original non-normal distribution. In other words, the population mean is the same as the sample mean.

Step-by-step explanation:

we need to calculate the distances between the points as the side lengths of the triangle.

these side lengths must satisfy the Pythagoras principle :

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle) and the longest of the 3 sides, a and b being the legs.

the distance between 2 points is again calculated via Pythagoras, as the coordinate differences (= the legs) with the distance as Hypotenuse create right-angled triangles.

this is then caked the distance formula, but it is all Pythagoras again.

AB² = (xB - xA)² + (yB - yA)² = (6 - -2)² + (2 - 2)² =

= 8² + 0² = 8²

AB = 8

AC² = (0 - -2)² + (6 - 2)² = 2² + 4² = 4 + 16 = 20

AC = sqrt(20)

BC² = (0 - 6)² + (6 - 2)² = (-6)² + 4² = 36 + 16 = 52

BC = sqrt(52)

as sqrt(20) is a little bit more than 4, and sqrt(52) is a little bit more than 7, 8 is the longest side and Hypotenuse.

if this is a right-angled triangle, then

8² = sqrt(20)² + sqrt(52)²

must be true.

but

64 = 20 + 52 = 72

is wrong.

so, the segments do not form a right-angled triangle.

By applying supply and demand concept, it can be concluded that:

a. Point of equilibrium for this market will be reached when p = 20 and q = 50

b. Consumers' surplus for this market when -150 < q < 50

c. Producers' surplus for this market when 50 < q < 130

Demand is the number of goods purchased or requested in the market at a certain price and time, while supply is the number of goods sold or offered in the market at a certain price and time.

Point of equilibrium will be reached when supply and demand are in balance.

We have the following supply and demand functions:

Supply: p = 15 + 0.1q

Demand: p= √(650- 5q)

A. The point of equilibrium occurs when supply and demand are in balance:

                                 15 + 0.1q = √(650- 5q)

                              (15 + 0.1q)² = 650 - 5q

                  225 + 3q + 0.01q² = 650 - 5q

0.01q² + 3q + 5q + 225 - 650 = 0

                    0.01q² + 8q - 425 = 0

                  q² + 800q - 42500 = 0

q² + 800q + 160000 - 202500 = 0

                 (q + 400)² - 202500 = 0

                                  (q + 400)² = 202500

                                     q + 400 = 450

                                                q = 50

As we know q, we can calculate the p:

p = 15 + 0.1q

  = 15 + 0.1 * 50

  = 20

B. The Consumers' surplus when demand > supply:

√(650- 5q) > 15 + 0.1q    ⇔    q < 50

which implies:

√(650- 5q) > 0                ⇔    q < 130

15 + 0.1q > 0                    ⇔    q > -150

So, the Consumers' surplus for this market when -150 < q < 50

C. The Producers' surplus when supply > demand:

15 + 0.1q > √(650- 5q)    ⇔    q > 50

which implies:

√(650- 5q) > 0                ⇔    q < 130

15 + 0.1q > 0                    ⇔    q > -150

So, the Producers' surplus for this market when 50 < q < 130

The probability of 35 people being selected before the first person with a phobia being chosen does not provide sufficient evidence to suggest that the ADAA claim is false. To determine if the ADAA claim is false, we would need to perform a statistical hypothesis test to compare the sample proportion of adults with phobias to the ADAA estimate of 8.7%. This would involve collecting data on a random sample of adults, calculating the sample proportion of adults with phobias, and comparing it to the ADAA estimate of 8.7%.

If the sample proportion is significantly different from 8.7%, we can conclude that there is evidence to suggest that the ADAA claim is false. However, without performing a statistical hypothesis test, we cannot make a conclusion about the validity of the ADAA claim based solely on the probability of 35 people being selected before the first person with a phobia is chosen.

Answer:

To find the value of (a - 1/a)^2 and (a - 1/a), we can start by squaring the given equation:

a^2 + 1/a^2 = 18

(a^2 + 1/a^2)^2 = 18^2

a^4 + 2 + 1/a^4 = 324

a^4 + 1/a^4 = 322

Now, to find (a - 1/a)^2, we can square the difference of a and 1/a:

(a - 1/a)^2 = a^2 - 2 + 1/a^2

We can substitute the value of a^4 + 1/a^4 = 322 into this equation:

(a - 1/a)^2 = 322 - 2

(a - 1/a)^2 = 320

To find (a - 1/a), we can take the square root of (a - 1/a)^2:

(a - 1/a) = √320

And, a^2 + 1/a^2 = 18, we can solve for a,

a^4 - 18a^2 + 1 = 0

(a^2 - 1)(a^2 - 18) = 0

a^2 = 1 or a^2 = 18

a = 1 or a = ±√18

So, in this case, the value of (a - 1/a)^2 is 320 and (a - 1/a) is √320.

Step-by-step explanation:

The closest value of x that would produce the box with the minimum surface area would be 117 ft.

The volume of a lidless box with height h and a square base with sides of length x is given by V = x^2 * h.

To have a volume of 117 ft^3, we have:

x^2 * h = 117

The surface area of a lidless box is given by:

A = 2x^2 + 4xh

We want to minimize this surface area while still keeping the volume of the box at 117 ft^3. To do this, we need to find an expression for h in terms of x, and then minimize A in terms of x.

From the volume equation, we can solve for h:

h = 117 / x^2

Substituting this expression into the surface area equation, we get:

A = 2x^2 + 4x * (117 / x^2)

= 2x^2 + 466 / x

Now, we can use calculus to find the minimum of A in terms of x.

The derivative of A with respect to x is:

dA/dx = 4x - 466 / x^2

Setting dA/dx equal to zero, we find the critical points:

4x - 466 / x^2 = 0

4x = 466

x = 116.5

We now need to check if x = 116.5 is a local minimum or maximum.

To do this, we need to examine the second derivative of A with respect to x:

d^2A/dx^2 = -932 / x^3

Since the second derivative is negative, this means that A has a local minimum at x = 116.5.

Hence, the value of x that produces the box with a minimum surface area is approximately 116.5 ft.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The function to model the rate at which the number of wolves in a forest is changing is E(t) = 31 cos (0.11t)

Here t is the time measured in weeks.

The time value is given as t = 7

Substitute the value of t in the equation -

E(t) = 31 cos (0.11t)

Apply the arithmetic operation of multiplication -

E(7) = 31 cos (0.11 × 7)

E(7) = 31 cos (0.77)

E(7) = 31 × 0.7179

E(7) = 22.2549
