On solving the provided question we can say that 2 decimal places =29.92 miles per hour

Integer and non-integer numbers are often expressed using the decimal numeral system. The Hindu-Arabic numeral system has been expanded to include non-integer values. Decimal notation is the name for the method used to represent numbers in the decimal system. A decimal is a number with a whole and a fractional component. Decimal numbers, which are in between integers, are used to express the numerical value of full and partially whole amounts. A decimal point separates the complete number and the fractional portion of a decimal number. The dot between the whole number and the fractions is known as the decimal point. A decimal number is, for instance, 25.5. In this instance, 25 is the entire number, while 5 is the

a)The standard deviation is given by σ = sqrt(np(1-p)) = sqrt(24 × 0.75 × 0.25) = 2.12 . b)Significantly low: μ - 2σ = 18 - 2 × 2.12 ≈ 13.76 ,Significantly high: μ + 2σ = 18 + 2 × 2.12 ≈ 22.24 ,c)z = (x - μ) / σ = (3 - 18) / 2.12 ≈ -7.08.

A group of 24 peas with green pods has a binomial distribution with n = 24 and p = 0.75. The mean is calculated as = np = 24 0.75 = 18, and the standard deviation is calculated as = sqrt(np(1-p)) = sqrt(24 0.75 0.25) = 2.12 (rounded to two decimal places).

b) The range rule of thumb states that results that deviate from the mean by more than two standard deviations are considered significantly low or significantly high. In this case, the values separating significantly low and significantly high results are:

Significantly reduced: - 2 = 18 - 2 2.12 13.76

Significantly greater: + 2 = 18 + 2 2.12 22.24

c) To see if a result of three peas with green pods is significantly low, we must calculate its z-score, which is given by:

z = (x - μ) / σ = (3 - 18) / 2.12 ≈ -7.08

Because the z-score is much lower than -2, the cutoff for significantly low results, we can conclude that a result of 3 peas with green pods is significantly low.

The inverse of the given function is f(x) = 2x/(1 - x)

What is a function?

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two varying quantities.

Given function is

f(x) = x/(2+x)

Assume that y = f(x) = x/(2+x)

Solve y = x/(2+x) for x:

y = x/(2+x)

Multiply (2+x) on both sides:

y(2+x) = x

2y + xy = x

Subtract xy from both sides:

2y = x - xy

2y = x(1 - y)

x = 2y/ (1 - y)

Now replace x with y and y with x:

y = 2x/(1 - x)

To find the weight of 4.3 cubic feet of water, we need to first find the number of gallons of water that 4.3 cubic feet holds and then multiply that by the weight of 1 gallon of water.

1 cubic foot holds 7.48 gallons of water, so 4.3 cubic feet holds 4.3 x 7.48 = 31.964 gallons.

1 gallon of water weighs 8.33 pounds, so 31.964 gallons of water weigh 31.964 x 8.33 = 265.9012 pounds.

Therefore, 4.3 cubic feet of water weigh 265.9012 pounds.

To find the weight in tons, we need to divide the weight in pounds by 2000:

265.9012 pounds ÷ 2000 = 0.13295 tons

So 4.3 cubic feet of water weigh 0.13295 tons.

Answer:

0.13314 tons.

Step-by-step explanation:

We can start the calculation by first converting the cubic feet of water to gallons and then converting the gallons to pounds.

Conversion from cubic feet to gallons:

4.3 cubic feet = 4.3 cubic feet * 7.48 gallons/cubic foot = 32.084 gallons

Conversion from gallons to pounds:

32.084 gallons = 32.084 gallons * 8.33 pounds/gallon = 266.279 pounds

Conversion from pounds to tons:

266.279 pounds = 266.279 pounds / 2000 pounds/ton = 0.13314 tons

So, 4.3 cubic feet of water weigh 266.279 pounds or 0.13314 tons.

Using the fact that the figures are similar, we will find that MN = 12.4

We know that both figures are similar, then there is a scale factor that relates them.

We know the length of two correspondent sides, these are:

HI and LM

HI = 3

LM = 18.6

if k is the scale factor, then we can wite:

3*k = 18.6

k = 18.6/3 = 6.2

Now the length of MN will be 6.2 times the length of the correspondent side on the smaller figure:

MN = 6.2*2 = 12.4

Answer: The formula for exponential decay is given by:

P(t) = P0 * e^(-rt)

where P(t) is the profit at time t, P0 is the initial profit, r is the rate of decrease in percentage, and t is the time elapsed in years.

In this case, P0 = $9500, r = 0.9%, and t = 5 (the time elapsed from 2014 to 2019).

First, we need to convert the rate of decrease from a percentage to a decimal:

r = 0.9% / 100 = 0.009

Now, we can plug in the values into the exponential decay formula:

P(5) = $9500 * e^(-0.009 * 5) = $9500 * e^(-0.0455)

We can calculate the value of e^(-0.0455) using a calculator or mathematical software. The result is approximately 0.955.

Therefore, the profit in 2019 is:

P(5) = $9500 * 0.955 = $9027.25

So, the profit in 2019 would be $9027.25.

1) The length of the missing side of the right triangle is 34.

2) The values of the six trigonometric functions of θ are:

sin θ = sin A = 8/17

cos θ = cos A = 15/17

tan θ = tan A = 8/15

csc θ = csc A = 17/8

sec θ = sec A = 17/15

cot θ = cot A = 15/8

What is Pythagorean Theorem?

Pythagoras Theorem is a method for calculating the missing length of a right-angled triangle. The triangle has three sides: the hypotenuse (which is usually the longest), the opposite (which does not touch the hypotenuse), and the adjacent (which is always the shortest) (which is between the opposite and the hypotenuse).

Part 1

To find the length of the missing side (c) of the right triangle, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, we have:

a² + b² = c²

Substituting the given values, we get:

16² + 30² = c²

Simplifying, we get:

256 + 900 = c²

1156 = c²

Taking the square root of both sides, we get:

c = sqrt(1156) = 34

Therefore, the length of the missing side of the right triangle is 34.

Part 2

To find the values of the six trigonometric functions of θ, we need to know one of the acute angles of the triangle. Let's call the acute angle opposite side a as angle A. Using the given values, we can find the sine, cosine, tangent, cosecant, secant, and cotangent of angle A as follows:

sin A = a/c = 16/34 = 8/17

cos A = b/c = 30/34 = 15/17

tan A = a/b = 16/30 = 8/15

csc A = 1/sin A = 17/8

sec A = 1/cos A = 17/15

cot A = 1/tan A = 15/8

Therefore, the values of the six trigonometric functions of θ are:

sin θ = sin A = 8/17

cos θ = cos A = 15/17

tan θ = tan A = 8/15

csc θ = csc A = 17/8

sec θ = sec A = 17/15

cot θ = cot A = 15/8
