The probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean  and standard deviation , the z-score of a measure X is given by:

Z = (X - mean)/S.D

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 2.8 feet and a standard deviation of 0.5 feet.

Find the probability that an individual man’s step length is less than 2.2 feet.

This is the p-value of Z when X = 2.2. So

Z = (2.2 - 2.8)/0.5

Z = 0.6/0.5 = 1.2

Z = 1.2

has a p-value of 0.10

Therefore, the probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

The number of fashion magazines subscription that were sold is approximately 58.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.

In other words, percentage is a fraction or a ratio in which the value of whole is always 100.

Therefore, Carolyn’s homeroom sold 207 magazine subscriptions. Of the magazine subscriptions sold, 28 percent were fashion magazines.

The number of fashion magazine subscriptions that were sold can be calculated as follows:

number of fashion magazine sold = 28% of 207

number of fashion magazine sold = 28 / 100 × 207

number of fashion magazine sold = 5796 / 100

number of fashion magazine sold = 57.96

Therefore, about 58 fashion magazines were sold.

B. Number of possible outcomes with red at least ounce in 4 spins: 175.

C. Number of possible outcomes with red at least ounce in 5 spins: 781.

The outcomes are obtained in two ways, as follows:

The combination formula calculates the number of different combinations of x objects from a set of n elements, according to the equation presented as follows:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

From item a, there are 5 outcomes with 3 and 2 repetitions, hence the number of results is obtained as follows:

[tex]C_{5,3} = \frac{5!}{3!2!} = 10[/tex]

It states that the number of outcomes of n independent trials is given by the multiplication of the number of outcomes for each trial.

For item b, we have that:

Hence the total number of outcomes, without considering the restriction is:

Total = 4^4 = 256.

With no red results, the number of outcomes is:

Total no red = 3^4 = 81.

Hence the number of outcomes with at least one red result, considering complementary events, is:

256 - 81 = 175.

The value of x in the given trigonometric function is 7.37

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios. The other important trig ratios, cosec, sec, and cot, can be derived using the sin, cos, and tan respectively.

5cos(5x) = 4

divide both sides by 5, it becomes,

cos(5x) = 4/5

cos(5x) = 0.8

taking Arc cos on both sides

5x = Arc cos 0.8

The value of v is -12.5 when u = 15, t = 8, and s = 40.

According to the question,

We have the following expression:

s = (u+v)[tex]t^{2}[/tex]

We have the following values:

u = 15, t = 8, s = 40

Now, we can easily find the value of v by putting all these values in the given expression.

So, we have the following expression:

40 = (15+v)8*8

40 = (15+v)16

Multiplying 16 into the bracket:

40 = 15*16+16v

40 = 240+16v

Subtracting 240 from both sides:

40-240 = 16v

-200 = 16v

Dividing by 16 on both sides:

-200/16 = v

v = -12.5

Hence, the value of v is -12.5 when u = 15, t = 8, and s = 40.

The equation of the function is: y = 11.5x.

The slope = 11.5 garbage bag per hour.

Y-intercept = 0 bag at 0 hour.

The domain: number of hours

Range of the function: number of garbage bags filled.

138 bags will be filled in 12 hours.

The equation of a function can be written as y = mx + b in slope-intercept form. Here, we have:

Given the graph with the points that represents the number of garbage bags filled as a function of time as:

(6, 69); (5, 57.5); (4, 46); (2, 23); (1, 11.5); (3, 34.5)

Use two points, (6, 69) and (4, 46) to find the slope of the function:

Slope (m) = change in y / change in x = (69 - 46)/(6 - 4)

Slope (m) = 23/2

Slope (m) = 11.5

To find the y-intercept (b), substitute m = 11.5 and (x, y) = (6, 69) into y = mx + b:

69 = 11.5(6) + b

69 = 69 + b

69 - 69 = b

b = 0

To write the equation of the function, substitute m = 11.5 and b = 0 into y = mx + b:

y = 11.5x + 0

y = 11.5x

The slope, 11.5, means 11.5 garbage bags were filled per hour.

Y-intercept is zero, which means no bag was filled at 0 hour.

The domain is the set of the number of hours, while the range of the function is the set of number of garbage bags filled.

To find the number of garbage bags that volunteers fill in 12 hours, substitute x = 12 into y = 11.5x:

y = 11.5(12)

y = 138 bags.

The perpendicular of the right triangle is 2.62441 inches and the base of the triangle is 3.0164 inches.

According to the question,

We have the following information:

A right triangle has a hypotenuse of length 4 inches. And one angle is 41°.

Now, we will use trigonometric functions of Sin and Cos to find the length of each leg of this triangle.

Sin 41 = Perpendicular/hypotenuse

Perpendicular = 0.6561*4

Perpendicular = 2.62441 inches

Cos 41 = base/hypotenuse

Base = 0.7541*4

Base = 3.0164 inches

Answer:

y = 5x/6 + 3/2

Step-by-step explanation:

First, find the slope (m):

m=(y2-y1)/(x2-x1)

m=(9-4)/(9-3)

m=5/6

y=mx+b ==> slope-intercept form equation

y = 5x/6 + b==> substitute the value of the slope for m

9 = 5(9)/6 + b ==> substitute a point (x, y) or (9, 9) into the equation

9 = 45/6 + b ==> simplify

(9 = 45/6 + b)*6 ==> multiply the equation by 6 to remove denominators

54 = 45 + 6b ==> simplify

54 - 45 = 45 - 45 + 6b ==> solve for b

9 = 6b

9/6 = 6b/6

b = 3/2

Complementary angles always add to 90 degrees.

Draw a right angle, aka 90 degree angle. Plot points A, B and D on it as shown below. Then add point C somewhere inside the rectangular region formed by this right angle. Lastly, connect a segment from B to C. This helps form angles ABC and CBD. Note how these smaller angles combine to a 90 degree angle.

(angleABC) + (angleCBD) = angle ABD = 90 degrees

The angles are adjacent because they share a common wall, which in this case is segment BC.
