Answer:

To solve the equation Z - 2/5=1/3, we need to get Z alone on one side of the equation.

First we add 2/5 to both sides of the equation to get

Z - 2/5 + 2/5 = 1/3 + 2/5

Z = 1/3 + 2/5

To combine the fractions on the right side of the equation, we need to find a common denominator.

The common denominator of 1/3 and 2/5 is 15

So we can convert 2/5 to 9/15

Z = 1/3 + 9/15

Now we can add the fractions

Z = 12/15 + 9/15

Z = 21/15

So the solution to the equation is Z = 21/15

Step-by-step explanation:

By Linear Function f(x) = -4 + 2 and g(x) = x - 3 this we get the Value -2.

The slope-intercept form or the point-slope form are used to find a linear function.

With the aid of an example, the procedure for determining a linear function is the same as determining a line's equation.

When "m" and "b" are real numbers, then a function has the form f(x) = mx + b.

Examples :

f(x) = -4 + 2,g(x) = x - 3: -2

Steps

Find  f ° g given f(x) = -4 + 2, g(x) = x - 3

f ° g = f(g (x))

Constant function results in a constant

f (x )  = -4 + 2

-4 + 2 = -2

Answer = -2.

The dominant K allele is necessary for hearing, and the dominant M allele causes deafness regardless of the other genes present. What fraction of the offspring of parents with the genotypes KkMm and Kkmm will most likely be deafi is 1/2 so c option is correct

The percentage that the offspring will be deaf is 75%. Two punnet squares are needed each for km and Kkmm individuals. In punnet square 1, half of the genotypes are Km and km while half are Mm and kk in punnet square 2. The two punnet squares are then combined to form a final one where a quarter of the offspring is deaf.

What does genotype mean?

In a wide sense, the word"genotype" refers to the genetic makeup of an organism;  it defines an organism's complete set of genes. In a more thin sense, the term can be used to guide the alleles, or variant forms of a gene, that are carried by an organism.

Regression toward the mean is most likely to account for the higher scores. So the option 2 is correct.

The answer to this query is based on a long-term investigation. An observational study that tracks the same people across time, sometimes from birth to death, is called a longitudinal study.

The right response is regression to the mean. When a sample point for a random variable is extreme, regression toward the mean is the phenomena that results, with subsequent measurements, in a point that is closer to the mean or average.

Answer:

Shortest = 10ft

Middle = 18 ft

Longest = 26ft

Step-by-step explanation:

(btw u can make a diagram to make it easier to visualise)

Let shortest side of triangle be x

So:

1st side = 2x+6

2nd side = x

3rd side = x+8

These sides all equal to 54 ft (perimeter)

2x+6 + x + x+8 = 54

4x + 14 = 54

4x = 40

x = 10

Now that we know the shortest side just sub it back into the equations!

Answer:

5 tickets for $12.50

Step-by-step explanation:

because in that deal the ticket only costs $2.05

and in the second deal which is 8 tickets for $20.60 the ticket costs 2.57

The ratios that are equivalent to 12:6 are (a) 10 : 5 and (b) 18 : 9

From the question, we have the following parameters that can be used in our computation:

Ratio = 12 : 6

Divide both sides of this ratio by 6

So, we have the following representation

Ratio = 2 : 1

Multiply the ratio by 9

Ratio = 18 : 9

Multiply the ratio by 5

Ratio = 10 : 5

The distance of the town from the base of the cliff  is; 62.42 ft

The 6 trigonometric ratios are;

sin θ = opposite/hypotenuse

cos θ = adjacent/hypotenuse

tan θ = opposite/ adjacent

sec θ = 1/cos θ

cosec θ = 1/sin θ

cot θ = 1/cot θ

We are given the angle of depression as 10 degrees. By definition of alternate angles, the angle the hypotenuse formed will make with the base of the town is 10 degrees.

Since the height from the cliff to the town is 354 ft, then we can use trigonometric ratio to find the distance of the town from the base of the cliff as;

The coordinates of the image of the point Q is Q'(3, 6).

Transformation of geometrical figures or points is the manipulation of a given figure to some other way.

Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.

From the given graph, we have point Q(-4, 4).

Here the point is translated.

After translation, the original figure is shifted from a place to another place without affecting it's size.

The rule of translation is given as the point (x, y) is translated as (x + 1, y + 2).

So the given point is (-4, 4).

(-4, 4) after translation becomes by the definition (-4 + 1, 4 + 2).

So the required point is (-3, 6).

Answer: Based on the information provided, we can use the proportion of blue m&ms found in the sample (82 out of some larger total number of m&ms) to estimate the total number of m&ms in the entire bag.

If we let x be the total number of m&ms in the bag, we can set up the proportion:

82/x = blue m&ms / total m&ms

To solve for x, we can cross-multiply and divide by 82:

x = 82 * total m&ms / blue m&ms

x = 82 * 1

x ≈ 82

Therefore, based on the sample, we expect there to be approximately 82 m&ms in the entire bag, rounded to the nearest whole m&m.

It's worth noting that this is an estimation, and the actual number of m&ms in the bag may be different.

Step-by-step explanation:

Considering the figure, the value of x is calculated using adjacent angles concept and it is solved to be

The angle at PSR is 90 degrees

Also, angle PSQ and angle QSR are adjacent angles hence

angle PSQ + angle QSR = angle PSR = 90

90 = (5x − 12)∘ + (10x − 3)

opening the parenthesis

90 = 5x − 12 + 10x − 3

collecting like terms

90 + 12 + 3 = 5x + 10x

105 = 15x

isolating x by dividing through by 15

15x / 15 = 105 / 15

x = 7

Applying the Midsegment Theorem, the length of BC is: 10.

The Triangle Midsegment Theorem states that in a triangle, a line segment connecting the midpoints of two sides is parallel to the third side and is half as long.

From the information given we know that:

E is the midpoint of BC and D is the midpoint of AC.

Thus, applying the Midsegment Theorem, we have:

ED = 1/2(BA)

Substituting the values not expressive, we would get:

x + 2 = 1/2(4x - 6)

2(x + 2) = 4x - 6

2x + 4 = 4x - 6

The area a of the window as a function of the width x of the window 12x -(4 + π)x2/8

Let y be the height of the window's rectangular part, and let P represent the window's perimeter.

P then equals x plus 2y plus the length of the semicircular part. The radius of the semicircular part is x/2.

So, P = x + 2y + (1/2)(circumference)

     P = x + 2y  + (1/2)(2)π(x/2)

     P = x + 2y +πx/2 = 24

2y = 24 - x - πx/2

y = 12 - x/2 - πx/4 = 12 - (2 + π)x/4

A = xy + (1/2)π(x/2)2

   = x(12 - (2 + π)x/4) + πx2/8

The surface area of the interior of the box is the total area of the interior walls of the box.

This can be calculated by subtracting the area of the 5 unit square removed from the total area of the original 20 by 30 unit rectangular sheet of cardboard. This gives us an area of 450 units. To calculate the area of the interior walls, we need to multiply the length and width of the remaining rectangle. This gives us a length of 15 units and a width of 25 units, which gives us a total area of 375 units. Therefore, the surface area of the interior of the box is 375 square units.

Answer: To find the number of balls Ivan makes each day, we need to divide the total volume of lead used each day by the volume of one ball.

The formula for the volume of a sphere is:

V = (4/3) * π * r^3

Where V is the volume, π is pi and r is the radius of the sphere.

We know the radius of the sphere is 3 inches so we can use this information to find the volume of one ball.

V = (4/3) * π * 3^3

V = (4/3) * π * 27

V = 36 * π

Now we know the volume of one ball is 36π cubic inches, we can divide the total volume of lead used per day by the volume of one ball to find the number of balls made per day.

28,260 in^3 / 36π in^3/ball = 785.833 balls/day

Rounding to the nearest hundredth, Ivan on average makes 785.83 balls/day.
