Answer:

Step-by-step explanation:

if you move the preimage on the image you can see that the two figures are equals

The inverse function is given by f⁻¹(x) = 1.06x.  2 euros is equivalent to 2.12 U.S. dollars. 4 euros is equivalent to 4.24 U.S. dollars

Given that: the two different currencies is modeled by a linear function f(x) = x/1.06

where, x = an amount in U.S. dollars and f(x) = the equivalent amount in euros

To find the inverse function f⁻¹(x). Let y = f(x):

y = x/1.06

x = 1.06y

Since x = f⁻¹(y) = 1.06y

Thus, f⁻¹(x) = 1.06x

Note: f⁻¹(x) will help you convert from euros to dollar

2 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(2) = 1.06(2) = 2.12

Thus, 2 euros is equivalent to 2.12 U.S. dollars

4 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(4) = 1.06(4) = 4.24

Thus, 4 euros is equivalent to 4.24U.S. dollars

Step-by-step explanation:

2 +3 = 5    

The maximum and minimum values of the given function will be equal to -1.47 and -6.52.

The 2nd equation in x is known as a quadratic function. ax² + bx + c = 0 is the quadratic equation in standard form, wherein there a and b are the coefficient, x is the constant, and c is the constant.

As per the equation given in the question,

f(x) = x² + 8x + 9.6

D = b² - 4ac

= 8² - 4(1)(9.6)

D = 25.6

The Area of the Shaded Region is 184.61 sq. mm

What is Area?

The quantity area indicates the extent of a region on a planar or curved surface. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina.

Solution:

Area of the Shaded Region = Area of Rectangle - 2 * Area of Circles

Area of Recatangle = Length * Breadth = 21 * 13 = 273 sq. mm

2 * Area of Circle = 2* πr² = 2 * 22/7 * 7.5/2 * 7.5/2

Using percentages, we can determine that the Luce family pays $16.34 in state tax because there are no federal withholding exemptions.

A percentage is a relative figure that has the ability to represent 1/100th of any quantity.

Since 1% denotes one percent, 100 percent and 200 percent indicate the full amount and double the quantity, respectively.

By multiplying by 100 and inserting the "percentage sign"%, a ratio and fraction can be transformed into a percentage.

So, Luce is single and makes $763 twice weekly.

She does not request any compensation from federal withholding.

The value of this amount ranges from $760 to $780.

If we look at the table in the issue, the federal tax for this slab is $86.

Federal taxes now make up 19% of all state taxes.

Hence, the $86 in federal tax at a rate of 19% is:

Tax = 86 * 19/100

Tax = 16.34

Therefore, using percentages, we can determine that the Luce family pays $16.34 in state tax because there are no federal withholding exemptions.

Using the binomial distribution, it is found that there is a 0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

For each chicken, there are only two possible outcomes, either they are contaminated, or they are not. The chickens are independently selected, hence, the binomial distribution is used.

What is the binomial probability distribution formula?

The formula is:

P(X=x) = Cₙ,ₓ.pˣ.(1-p)ⁿ⁻ˣ

Cₙ,ₓ = n!/x!(n-x)!

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

About 30% of frozen chickens are contaminated, hence p=0.3.

Chickens are delivered to grocery stores in crates of 24, hence n=24

The probability that a certain crate has more than 4 contaminated chickens is:

P(X>4)=1-P(X≤4)

In which:

P(X≤4) = (P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)

Then

P(X=x) =  Cₙ,ₓ.pˣ.(1-p)ⁿ⁻ˣ

P(X=0) = C₂₄,₀.(0.3)⁰.(0.7)²⁴ = 0.0002

P(X=1) = C₂₄,₁.(0.3)¹.(0.7)²³ = 0.0020

P(X=2) = C₂₄,₂.(0.3)².(0.7)²² = 0.0097

P(X=3) = C₂₄,₃.(0.3)³.(0.7)²¹ = 0.0305

P(X=4) = C₂₄,₄.(0.3)⁴.(0.7)²° = 0.0687

Hence

P(X≤4) = (P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)

= 0.0002+0.0020+0.0097+0.0305+0.0687

= 0.1111

0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

The chances that the revenue on the first show will exceed $800 when mean revenue is $336.25 and standard deviation is $38.16 is essentially zero. i.e. 0

A normal distribution is a type of continuous probability distribution in which the majority of data points cluster in the middle of the range, while the remainder taper off symmetrically toward either extreme. The mean of the distribution is also known as the middle of the range.

The normal distribution is primarily used to calculate the likelihood of an observation in a distribution falling above or below a given value.

Given,

Mean, [tex]\mu[/tex] = 336.25

variance, [tex]\sigma^2[/tex]= 1456

standard deviation, [tex]\sigma = \sqrt{1456}[/tex] = 38.16

Answer: 68600

hope it helps!

Answer:  This is a valid probability distribution.

The P(x) values add to 1; each P(x) is between 0 and 1 inclusive.

============================================================

Further Explanation:

A valid probability distribution is when,

The given data table is:

[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{P(x)}\\\cline{1-2}1 & 0.49\\\cline{1-2}2 & 0.05\\\cline{1-2}3 & 0.32\\\cline{1-2}4 & 0.07\\\cline{1-2}5 & 0.07\\\cline{1-2}\end{array}[/tex]

It's fairly clear that rule 2 has been satisfied. Something like [tex]0 \le 0.49 \le 1[/tex] is indeed a true statement. It's like saying 49% is between 0% and 100%. The other P(x) values are similar in nature.

---------

Let's see what the P(x) probability values add to:

0.49+0.05+0.32+0.07+0.07 = 1

We see that rule 1 has been met as well.

Since both rules have been satisfied, this means we have a valid probability distribution.

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

2. Calculate the odds of exposure for controls: 108/436 = 0.25

3. Divide the odds of exposure for cases by the odds of exposure for controls: 2.2/0.25 = 8.8

4. Finally, the odds ratio for the association between exposure to EMF's and breast cancer is 2.2.

The odds ratio for the association between exposure to EMF's and breast cancer can be calculated by dividing the odds of exposure for cases by the odds of exposure for controls. To calculate this, first take the number of cases exposed (11) and divide it by the number of cases not exposed (5). This will give the odds of exposure for cases (2.2). Second, take the number of controls exposed (108) and divide it by the number of controls not exposed (436). This will give the odds of exposure for controls (0.25). Finally, divide the odds of exposure for cases (2.2) by the odds of exposure for controls (0.25). This will give the odds ratio for the association between exposure to EMF's and breast cancer (2.2).

Let's represent the length of the side opposite angle A "BC" and the length of the side adjacent to angle A "AC". We can then use the sine function to find BC:

sin(A) = BC / AC

Substituting the given values, we get:

sin(24°) = BC / 14

We can use a calculator or look up the value of sin(24°) to get:

sin(24°) ≈ 0.406

Solving for BC, we get:

BC = 14 * sin(24°) ≈ 5.72

To find AC, we can use the cosine function:

cos(A) = AC / AC

Substituting the given values, we get:

cos(24°) = AC / 14

We can use a calculator or look up the value of cos(24°) to get:

cos(24°) ≈ 0.913

Solving for AC, we get:

What is a linear equation?

Equation shows the comparison between two algebraic expressions by connecting the two algebraic expressions by an equal to sign

A one degree equation is called linear equation

Let the number of cupcakes ordered by each club be c

The band would like to order cupcakes from Walmart at a cost of $3.35 per cupcake and a $13.00 order fee

Total amount spent = $(13 + 3.35c)

The orchestra would like to order cupcakes from Publix at $2.90 each

and a $22.50 order fee

Total amount spent = $(22.5 + 2.90c)

By the problem,

The linear equation is

13 + 3.35c = 22.5 + 2.90c

3.35c - 2.90c = 22.5 - 13

0.45c = 9.5
