On the basic of empirical rule, the estimate value of proper Millatti of a zebra living between 16. 6 and 24. 4 years is 0.6826.

We have, the lifespans of zebras in a particular zoo or normally distributed.

Average zebra lives,µ = 20.5 years

Standard deviations,σ = 3.9 years

We have to estimate the proper Millatti of a zebra living between 16. 6 and 24. 4 years.

In line accordance with the empirical rule : is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).The rule states that (approximately):

We have to determine value of

P(16.6 < x< 24.4 ). The Z-Score formula, Z is defined as (x - µ)/σ . Now,

Z = (24.4 - 20.5)/3.9

=> Z = 3.9/3.9

=> Z = 1

This value of Z = 1 tells us that row score for 24.4 years is one standard deviations from mean. In other words, 68% of the values between Z = -1 and Z = 1 , i.e., -1 < z < 1. Normal distribution is symmetric, so half area above the Z = 1 and half below Z = -1. So, P( -1 < z < 1) = P(16.6< x<24.4 ).

so the probability of a zebra living between 16. 6 and 24. 4 years is P(16.6 < x< 24.4 ),

= P( -1 < z < 1)

= P( z> 1 ) - P( z< -1)

= 0.68269

Hence, the required probability is 0.6826.

The value of x is √589. The ladder will reach √589 feet up of the wall.

What is the right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

Given that a ladder is placed against a wall. The length of the ladder is 25 feet. The distance of the ladder from the wall is 6 inches. Thus it forms a right triangle.

Assume that by using the ladder a man reaches x feet up the wall.

Then the base of the right triangle is 6 inches.

The hypotenuse is 25 inches. The height of the right triangle is x inches.

Applying Pythagorean theorem:

6² +x² = 25²

36 + x² = 625

x² = 625 -36

x² = 589

Taking square root on both sides:

x = √589 feet

The quarterly decay rate is given by \rm P = 200(0.9875)^n  and this can be determined by using the exponential decay function.

In mathematics, exponential decay refers to the process of decreasing an amount at a constant percentage rate over time. It may be stated as y=a(1-b)x, where y is the final amount, an is the original amount, b is the decay factor, and x is the time elapsed.

A school of fish has a population of 200.

The population is decreasing at a rate of 5% a year.

The formula of exponential decay is given by the equation:

[tex]\rm P = P_0\left(1- \dfrac{r}{100}\right)^n ----- (1)[/tex]

where n is the number of quarters for total decay, r is the rate of decay per quarter,P_0 is the initial population and P is the final population.

Now, put the values of known terms in the equation (1).

Answer:

If for every 5 calendars that Josh sold, Laure sold 4, and Josh sold 45 calendars last month.

Lauren sold 4/5 * 45 calendars = 36 calendars last month.

Step-by-step explanation:

Answer:

We know that for every 5 calendars Josh sold, Lauren sold 4. This is a ratio of 5:4, which means that for every 5 calendars Josh sells, Lauren sells 4.

We also know that Josh sold 45 calendars last month. We can use this information to find out how many calendars Lauren sold by using the ratio of 5:4.

We can set up the equation:

5/4 = 45/x

Where x represents the number of calendars that Lauren sold.

We can solve for x by multiplying both sides of the equation by x:

5x = 4*45

x= 4*45/5

x= 36

So Lauren sold 36 calendars last month.

The  constant of proportionality is  10  

What are direct and indirect variations ?

One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.

When one parameter declines while the other rises or vice versa, this is known as inverse variation. This means that the magnitude or absolute value of one item decreases as the other quantity rises, resulting in a constant value for their product. This item is also referred to as the proportionality constant.

From the table, y values increase as the x values increase.

This is a direct variation and is given by y=kx.

Let's call the angle of elevation of the zip-line as "x"

We can use the tangent function to find the angle of elevation:

tan(x) = Opposite/Adjacent

Where opposite is the height of the pole (70 feet) and adjacent is the horizontal distance between the base of the pole and the stake (70 feet).

So we can write:

tan(x) = 70/70

As the adjacent and opposite sides are the same, the tangent of the angle is 1.

The angle of elevation of the zip-line is x = arctan(1) = 45 degrees

To find the amount of cable needed we can use the Pythagorean theorem, as we have a right triangle with the zip-line as the hypotenuse, the height of the pole as one leg, and the horizontal distance between the base of the pole and the stake as the other leg

The cable length is equal to the hypotenuse of the right triangle, which can be calculated as the square root of the sum of the squares of the other two sides:

cable length = √(70² + 70²) = √(4900 + 4900) = √(9800) = 99 feet

So the amount of cable needed to make the zip-line is 99 feet.

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

As mentioned above, we use natural logs (i.e., logarithms in base e) because coefficients on the natural-log scale may be directly interpreted as roughly proportionate differences: for example, with a coefficient of 0.06, a change of 1 in x corresponds to a roughly 6% change in y, and so on.

The fact that the sum of two negatives is positive is related to the fact that the inverse of a positive number is that positive number back again.

A negative number in mathematics represents the reverse.

A negative number is one that is less than zero in the real number system.

Negative numbers are frequently used to indicate how great a loss or a shortage is.

One could consider an unpaid debt to be a negative number.

The inverse of a positive number is that positive number back again, which is related to the fact that the product of two negatives is a positive.

A minus sign and a negative sign are combined to form a plus sign when a negative number is subtracted from a negative number (-).

The final output has a positive sign when the magnitude of the second operand is larger than the magnitude of the first operand.

When a negative number is subtracted, the two negatives add up to a positive. −10−(−10) is not −20.

As an alternative, consider how one of the negative signs could be turned upright in order to cross over the other and create a plus.

Therefore, the fact that the sum of two negatives is positive is related to the fact that the inverse of a positive number is that positive number back again.

​we need to find an expression (polynomial) that should be added to 4x⁴ - 2x³ - 6x² + x - 5 so that the result is exactly divisible by 2x² + 3x - 2

If we divide a polynomial  f(x) = 4x⁴ - 2x³ - 6x² + x - 5 by g(x) = 2x² + 3x - 2 using polynomial long division method, the result is:
