Answer:

w = 39

Step-by-step explanation:

3w + 9 + 2w - 24 = 180 , that is

5w - 15 = 180 ( add 15 to both sides )

5w = 195 ( divide both sides by 5 )

The probability that the child is not affected by  the disorder is \frac{5}{6}

Probability is simply the likelihood of something occurring.

It is an autosomal recessive disorder because all of the defective ones are recessive. So, when a 2nd generation 3rd individual marries a 2nd generation 4th individual, the probability of their child having a genetic disease is [tex]\frac{1}{6}[/tex]. The parents must be heterozygous for the child to be diseased, and the probability of an individual being heterozygous is [tex]\frac{2}{3}[/tex]. 2nd generation, 3rd individual, and the probability of disease in the child is [tex]\frac{1}{4}[/tex], so [tex]\frac{2}{3} *\frac{ 1}{4} = \frac{1}{6}[/tex].

As a result, the probability of a child having a genetic disorder is [tex]\frac{1}{6}[/tex].

then the probability of child not having any genetic disorder is [tex]1-\frac{1}{6} =\frac{5}{6}[/tex].

Answer:

x = 1

Step-by-step explanation:

Given equation,

→ 3(6x - 2) = 2(3x + 3)

Now the value of x will be,

→ 3(6x - 2) = 2(3x + 3)

→ (3 × 6x) - (3 × 2) = (2 × 3x) + (2 × 3)

→ 18x - 6 = 6x + 6

→ 18x - 6 - 6x = 6

→ 12x = 6 + 6

→ 12x = 12

→ x = 12/12

→ [ x = 1 ]

Let's check the value of x,

→ 3(6x - 2) = 2(3x + 3)

→ 3(6(1) - 2) = 2(3(1) + 3)

→ 3(6 - 2) = 2(3 + 3)

→ 3 × 4 = 2 × 6

→ 12 = 12

→ [ LHS = RHS ]

Hence, the value of x is 1.

For the given distribution the mean is 20.74  , the variance is  1.652   and the standard deviation is 1.2853   .

In the question ,

probabilities are given ,

the mean is given by the formula,

mean = [tex]\sum[/tex]x*p(x) ,

we get ,

mean = 19*0.21 + 20*0.23 + 21*0.30 + 22*0.13 + 23*0.13

= 3.99 + 4.6 + 6.3 + 2.86 + 2.99

= 20.74

For calculating the Variance we need to subtract the mean for every value x, then we square the result and multiply it by the respectively probability .

19 - 20.74 = -1.74 = (-1.74)²× 0.21 = 0.6357

20 - 20.74 = -0.74 = (-0.74)²× 0.23 = 0.1259

21 - 20.74 = 0.26 = (0.26)²× 0.30 = 0.0202

22 - 20.74 = 1.26 = (1.26)²× 0.13 = 0.2063

23 - 20.74 = 2.26 = (2.26)²× 0.13 = 0.6639

The variance = 0.6357 + 0.1259 + 0.0202 + 0.2063 + 0.6639

= 1.652

the standard deviation = √variance

= √1.652

= 1.2853

Therefore , the values are mean is 20.74  , the variance is 1.652  and standard deviation is 1.2853 .

Answer:

Read carefully each step for your fully understand it.

Step-by-step explanation:

To find the equation of a line that is perpendicular to the line y = 2x - 3 and contains the point (-5, 3), we need to find the slope of the perpendicular line.

To find the slope, we use the negative reciprocal of the slope of the given line. The slope of the given line is 2, so the slope of the perpendicular line is -1/2.

We can then use the point-slope formula to find the equation of the line that is perpendicular to y = 2x - 3 and contains the point (-5, 3).

The point-slope formula is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. Plugging in the values, we get:

y - 3 = -1/2 (x + 5)

We can then simplify this equation to get the final equation:

y = -1/2 x - 11/2

Therefore, the equation of the line that is perpendicular to y = 2x - 3 and contains the point (-5, 3) is y = -1/2 x - 11/2.

Answer:

The amount of carbon-14 in the fossil is 15% of the amount of carbon-14 in a living beetle.

This means that the amount of carbon-14 in the fossil is 0.15 * the amount of carbon-14 in a living beetle.

The age of the fossil can be found by dividing the half-life of carbon-14 by the logarithm of the ratio of the amount of carbon-14 in the fossil to the amount of carbon-14 in a living beetle.

This means that the age of the fossil is 5715 years / log(0.15).

The age of the fossil is approximately 5715 years / -1.1761.

Therefore, the age of this fossil is approximately <<4895.4683=4895>>4895 years.

At a constant rate of 400 miles per hour travel, the plane would be travelling from 32000 feet above the land.

The speed of an object is the ratio of distance and time it takes for the object to travel that distance.

Mathematically,

S = D/T

where

S is velocity

D is the distance traveled or distance traveled

T is the time it takes to travel that distance

Velocity is considered a scalar quantity. A scalar size only has a size. It does not provide information about the direction of object movement.

If an object moves at a constant speed, it means that the object moves the same distance in the same time interval.

Acceleration of an object is the ratio of velocity and time. vector size. Vector quantities have both magnitude and direction.

Mathematics,

a = v/t

When an object is in motion, its acceleration is never zero.

When an object moves, it moves a constant distance over time. Therefore, body positions cannot be the same from the same coordinate system.

Given in the question:

First the plane was travelling at a constant rate of 250  miles per hour.

Initial height was 20000 feet

Now,

As the speed increases and travels at a constant rate of 400 miles per hour.

Now,

   (400 /250 ) × 20000

=  1.6 × 20000

= 32000 feet

Thus, At a constant rate of 400 miles per hour travel, the plane would be travelling from 32000 feet above the land.

Answer: 8 years for her salary to be the same at both companies.

Step-by-step explanation:

To solve this problem, we can set up a system of linear equations to represent the salaries at each company. Let's say that the first company's salary is represented by the variable x, and the second company's salary is represented by the variable y. Since the first company offers a starting salary of $28,000 with a raise of $3,000 each year, we can represent this with the equation x = 28,000 + 3,000 * t, where t represents the number of years. Similarly, the second company offers a starting salary of $36,000 with a raise of $2,000 each year, so we can represent this with the equation y = 36,000 + 2,000 * t.

Since we want to find the number of years it will take for Joanne's salary to be the same at both companies, we can set the two equations equal to each other and solve for t:

x = 28,000 + 3,000 * t

y = 36,000 + 2,000 * t

x = y

28,000 + 3,000 * t = 36,000 + 2,000 * t

We can solve this equation by combining like terms on both sides of the equation:

28,000 + 3,000 * t = 36,000 + 2,000 * t

-8,000 = -1,000 * t

Dividing both sides of the equation by -1,000, we get:

8,000 = t

Thus, it will take Joanne 8 years for her salary to be the same at both companies.

Answer:

8 years

Step-by-step explanation:

y = salary

x = years

1st company: y = 3,000x + 28,000

2nd company: y = 2,000x + 36,000

3000x + 28000 = 2000x + 36000

subtract 2000x on both sides

1000x + 28000 = 36000

subtract 28000 on both sides

1000x = 8000

divide 1000 on both sides

x = 8

Answer:

3,398.7 square centimeters.

Step-by-step explanation:

The area of a square is the square of the side length, so the ratio of the areas of the mirrors is equal to the ratio of the side lengths squared. If the ratio of the side lengths of Mirror A to Mirror B is 5:6, then the ratio of the side lengths squared is 5^2:6^2 = 25:36. This means that the ratio of the areas of Mirror B to Mirror C is 25:36.

The ratio of the areas of Mirror B to Mirror C is 25:36, and the ratio of the areas of Mirror B to Mirror C is 16:25, so 25:36 = 16:25. This means that the ratio of the areas of Mirror B to Mirror C is 1:1.5.

The perimeter of Mirror C is 280 centimeters, which means that each side has a length of 280/4 = <<280/4=70>>70 centimeters. The area of Mirror C is the square of this side length, or 70^2 = <<70^2=4900>>4900 square centimeters.

Since the ratio of the areas of Mirror B to Mirror C is 1:1.5, the area of Mirror B is 1.5 times the area of Mirror C, or 1.54900 = <<1.54900=7350>>7350 square centimeters.

The ratio of the side lengths of Mirror A to Mirror B is 5:6, so the side length of Mirror A is 5/670 = <<5/670=58.333>>58.333 centimeters. The area of Mirror A is the square of this side length, or 58.333^2 = <<58.333^2=3398.68>>3398.68 square centimeters. Rounding to the nearest tenth of a centimeter, the area of Mirror A is 3398.7 square centimeters. Answer: {3,398.7}.
