The value of AB is,

⇒ AB = 5.9

(rounded to nearest tenth)

We have to given that,

A right triangle ABC is shown.

Now, By trigonometry formula,

we get;

⇒ cos 33° = Base / Hypotenuse

Substitute all the values, we get;

⇒ cos 33° = AB / 7

⇒ 0.84 = AB / 7

⇒ AB = 0.84 × 7

⇒ AB = 5.88

⇒ AB = 5.9

Answer:

47.1

Step-by-step explanation:

We know side LM corresponds with side OP with a factor of some number. The value of side LM is 8, and the value of side OP is 29. If we divide the two numbers, we will find the scale factor of which triangle NOP is larger than KLM. 29/8 simplifies to 3.625. Now, to find the value of side PN, we must find the side it corresponds to on triangle KLM. Because K corresponds with N, and M corresponds with P, we know the side that PN corresponds with on triangle KLM is side KM. Side KM has a value of 13, so side PN must be 3.625 times larger than 13.

13 times 3.625 = 47.125. The question says to round to the nearest tenth, so the answer would be 47.1

The 95 percent confidence interval for the mean time for all players is [8.273 – 10.727]

The term confidence interval is referred as mean of your estimate plus and minus the variation in that estimate.

Here we have given that the football coach randomly selected ten players and timed how long each player took to perform a certain drill.

And we need to find the  95 percent confidence interval for the mean time for all players.

While we looking into the given question, we know that the football coach randomly selected ten players and timed how long each player took to perform a certain drill.

Here the times (in minutes) were

=> 7.2 10.5 9.9 8.2 11.0 7.3 6.7 11.0 10.8 12.4

The frequency table of the given data is illustrated below.

And the mean and the standard deviation are obtained from the following table:

=> mean = 95/10 = 9.5

=> standard deviation = √35.42/9

=> √3.94 = 1.98

Now, the 95% confidence interval for the mean time for all players is is calculated as,

=> CI = x ± Z×σ/√n

=> CI = 9.5 ± 1.9600×1.98/√10

=> CI = 9.5 ± 1.227

Therefore, the Confidence Interval: 9.5 ±1.227 (±12.9%) [8.273 – 10.727].

The analysis is as attached below.

The data in the table can be modeled by this linear equation in slope-intercept form: y = 8x - 5.

The slope is 8, which means the wages earned increases at rate of 8 dollars per hour as the time increases.

The y-intercept is -5 and it represent the initial wages earned.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is represented by this mathematical expression;

y = mx + c

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (24.00 - 8.00)/(3 - 1)

Slope (m) = 16.00/2

Slope (m) = 8

At data point (1, 3), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 3 = 8(x - 1)

y = 8x - 8 + 3

y = 8x - 5

In hyperbolic geometry, the angle sum of a triangle is always less than 180 degrees.

A lune is a wedge of a sphere with angle θ, represented by L(θ) in the proof.

α, β, and γ are the three angles of the triangle.

4πr²+4area[αβγ]=2L(α)+2L(β)+2L(γ)

2(2πr²+2area[αβγ])=2(L(α)+L(β)+L(γ))

2πr²+2area[αβγ]=L(α)+L(β)+L(γ)

At this point, we need to use a theorem that states that a lune whose corner angle is θ radians has an area of 2θr².

2πr²+2area[αβγ]=2αr²+2βr²+2γr²

2πr²+2area[αβγ]=2r²(α+β+γ)

π+area[αβγ]r²=α+β+γ

At this point, it is clear that the sum of the angles is equal to π plus the area[αβγ]r² (which cannot be zero).

Step-by-step explanation            

Answer:

Around 2.9 gallons is equivalent to 11 liters.  

Step-by-step explanation:

Key skills needed: Conversion, Division, Equations

1) 1 gallon  = 3.79 liters

2) We want to find how many gallons 1 liter is equal to ---> Use the original equation and divide by 3.79 on both sides.

You will get --> 1 liter  = 1/3.79 gallons

3) To find how many gallons 11 liters is we multiply both sides by 11.

We will get 11 liters  = 11/3.79 gallons ---> 11/3.79 is 2.9 when rounded to the nearest tenth.

Therefore 2.9 gallons is the answer.

Answer:

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

Step-by-step explanation:

Black Diamond:  ChargeBD(h) = $50 + ($15/hr)h, where h is the number of hours spent skiing.

Bunny Hill:  ChargeBH(h) = $75 + ($10/hr)h

We equate these two formulas to determine when the cost of using the ski slopes is the same:

ChargeBD(h) = $50 + ($15/hr)h = ChargeBH(h) = $75 + ($10/hr)h

We must now solve for h, the number of hours spent skiing:

50 + 15h = 75 + 10h

Grouping like terms, we obtain:

5h = 25, and so h = 5 hours.

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

The GCF of the variable parts is x

c. The expected number of cones of ice cream when the temperature is 30°C is 90°C.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (100 - 60)/(45 - 5)

Slope (m) = 40/40

Slope (m) = 1

At data point (5, 60) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 60 = 1(x - 5)  

y = x - 5 + 65

y = x + 60

Part a.

Based on the equation above, the y-intercept is equal to 60.

Part b.

Based on the equation above, the slope is equal to 1.

Part c.

In this scenario, the expected number of cones of ice cream when the temperature is 30°C;

y = x + 60

y = 30 + 60

y = 90°C.

The answer given question : Is 50%,probability of each child inheriting two copies of the mutated gene is 25%.  And the Overall, without additional information about the genetic makeup of the second-generation partners, it is impossible to determine the exact probability of occurrence of PKU in their children.

phenylketonuria (PKU) is an inherited disorder caused by a mutation in a gene that produces an enzyme called phenylalanine hydroxylase. This enzyme is necessary for the breakdown of the amino acid phenylalanine, and without it, phenylalanine can build up to toxic levels in the body, leading to brain damage and other serious health problems.

PKU is an autosomal recessive disorder, which means that a person must inherit two copies of the mutated gene (one from each parent) in order to develop the condition. If only one copy of the mutated gene is inherited, the person is a carrier of the disorder but does not develop PKU.

Given that one of the four children in the first generation has PKU, we can assume that both parents are carriers of the disorder.  The probability of each of their children inheriting a single copy of the mutated gene (i.e., becoming carriers like their parents) is 50%, and the probability of each child inheriting two copies of the mutated gene (i.e., developing PKU) is 25%.

The occurrence of PKU in the second generation will depend on the genetic makeup of the partners who have children. If both partners are carriers, there is a 25% chance that each of their children will develop PKU. If one partner is a carrier and the other is not, there is no chance that their children will develop PKU, but each child will have a 50% chance of being a carrier

Answer:

\(-12\)

Step-by-step explanation:

Let that number be \(x\). We can build an equation, and solve for \(x\).

\(4\) less than half of \(x\) is \(x/2-4\).

\(2\) more than \(x\) is \(x+2\).

We are given that the two quantities are equal, so we have that \(x/2-4=x+2\).

Adding \(4\) to both sides gives \(x/2=x+6\).

Multiplying both sides by \(2\) gives \(x=2(x+6)=2x+12\).

Subtracting \(2x\) from both sides gives \(-x=12\).

Multiplying both sides by \(-1\) gives \(x=-12\).

So, the number is \(\boxed{-12}\) and we're done!

The space shuttle travels about 6713 miles per hour. Rounded to the nearest mile, this is approximately 6713 miles per hour.

What is a radius ?

In mathematics, the radius is a term used to describe the distance from the center of a circle or a sphere to any point on its surface. It is denoted by the letter "r".

The orbit of the space shuttle is circular, so the distance it travels in one orbit is equal to the circumference of the circle with a radius of 275 + 4000 = 4275 miles (275 miles above the Earth's 4000 mile radius).

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is the mathematical constant pi (approximately 3.14). Therefore, the distance traveled by the shuttle in one orbit is:

C = 2π(4275) ≈ 26851 miles

Since the shuttle orbits once every 4 hours, its average speed is:

distance/time = 26851/4 ≈ 6713 miles per hour

Therefore, the space shuttle travels about 6713 miles per hour. Rounded to the nearest mile, this is approximately 6713 miles per hour.
