The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a larger range, a low standard deviation suggests that the values tend to be near to the mean (also known as the anticipated value) of the collection.

The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical literature and equations to indicate standard deviation. Standard deviation may be written as SD.

EXPLANATION : The speed recordings follow an approximately normal distribution the mean of

100 readings was 2384 mph. with a standard deviation of 3.56mph

The speed limit read 20 mph

We have to find the number of standard deviations from the mean that the car going

under the speed hmit would be

Let the car going under the speed 20mph bey standard deviations away from mean

That is.

20 — 23.84 +y(3.56)

20—2384 —1.078651685

So the car going under the speed limit would be less than or equal to 107865 standard

A car traveling 34 mph

The number of standard deviations from the mean that the car is going at 34mph is given by

That is the car going at 34mph is 2.8539 standard deviations above the mean

A car traveling at 10mph

The number of standard deviations from the mean that the car going at 10mph is given by.

y= 2.8539

That is. the car going at 10mph is 3.8876 standard deviations

We know from the empirical nile that 99.7% of the observations he with in ±3 standard

deviations from the mean for a normally distributed data

But the speed of 10mph is not within these limits, where as 34 mph is within these limits

So the car is  travelling t 10mph is more unusual

The only ordered pair that is a solution to the given system of inequalities is (B) (2, 2).

To check which ordered pair is a solution to the system of inequalities

1. \(4x + 7y ≥ 21 and 2. 10x - 2y ≥ 16,\), we need to substitute the values of x and y in both equations.

Only then we can see which ordered pair satisfies both equations.

Let's check all the given options one by one:

a)\((4, 1)4(4) + 7(1) = 16 + 7 = 23\)

(This is true, so let's move on to the second equation)

\(10(4) - 2(1) = 40 - 2 = 38\)

(This is not true)Hence, (4, 1) is not a solution.

b) \((2, 2)4(2) + 7(2) = 8 + 14 = 22\)

(This is not true)\(10(2) - 2(2) = 20 - 4 = 16\)

Flying with the wind, a small plane flew 338 mi in 2 h. flying against the wind, the plane could fly only 312 mi in the same amount of time. So, the rate of the plane in calm air is 162.5 mph, and the rate of the wind is 6.5 mph.

Let's use variables to represent the unknowns in this problem:

- Let p represent the rate of the plane in calm air (in miles per hour).
- Let w represent the rate of the wind (in miles per hour).

When the plane is flying with the wind, the combined speed (plane + wind) is (p + w) mph. It flies 338 miles in 2 hours, so we have:

1. (p + w) * 2 = 338

When flying against the wind, the net speed (plane - wind) is (p - w) mph. It flies 312 miles in 2 hours, so we have:

2. (p - w) * 2 = 312

Now, we'll solve the two equations simultaneously. First, divide both sides of each equation by 2:

1. p + w = 169
2. p - w = 156

Next, add the two equations together to eliminate the w variable:

(p + w) + (p - w) = 169 + 156
2p = 325

Now, divide by 2 to find the rate of the plane in calm air:

p = 325 / 2
p = 162.5 mph

Now that we have the rate of the plane, we can find the rate of the wind by substituting the value of p back into either equation 1 or 2. Let's use equation 1:

162.5 + w = 169

Subtract 162.5 from both sides to find w:

w = 169 - 162.5
w = 6.5 mph

So, the rate of the plane in calm air is 162.5 mph, and the rate of the wind is 6.5 mph.

Answer:

y = 4x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = 8 , thus

y = 4x + 8 ← equation of line

The equation in slope-intercept form is y = 4x+8

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given that, a line has a y-intercept of 8 and a slope of 4.

We know that, the general equation of a line is given by, y = mx+c

where m is slope and c is the y intercept,

Here, m = 4 and c = 8

Therefore, the equation can be, y = 4x+8

Hence, The equation in slope-intercept form is y = 4x+8

Yes -20 degrees and 340 degrees are co-terminal angles

are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330°.

The coterminal angles can be positive or negative. To find the coterminal angles, simply add or subtract 360 degrees as many times as needed from the reference angle. All of these angles are coterminal angles.

co-terminal angles are found by adding or subtracting 360° to the angles.

for example the co-terminal angles of -10° = -10° + 360 = 350°

Similarly The co-terminal angles of -20 = -20+360 = 340°

therefore the -20 and 340 are co-terminal angles

Answer:

Step-by-step explanation:

The order of events from least likely to most likely are as follows:

The reason for this order is because of the chances of each event occurring. Event D has the least chance of occurring because no numbers in the set have a value less than or equal to 0. Event A is the next least likely because only one number in the set is greater than 0, which is the number 1. Event C is the next least likely because only two numbers in the set are at least 2 (2 and 3). Event B is the next least likely, as there are only five even numbers in the set (2, 4, 6, 8, and 10). Events E, F, G, and H are the most likely to occur, because of the number of numbers that are divisible by 3, and 5, and are prime numbers.

Hey there! I'm happy to help!

The slope is the steepness or incline of a line. From a graph, it is known as the rise over the run between two integer values. If you have a point at (1,1) and a point at (2,2), the rise (vertical difference) between them in 1 unit, and the run (horizontal difference) is 1 unit. 1/1 is 1, so the slope of a line that passes through these points is 1. This means that for every one unit to the right it goes, it goes one unit up.

The intercepts are where the line hits the x and y axes. By looking at a graph, you can find the y-intercept by seeing on what y-value the line intersects with the y-axis, and for the x-intercept you do so with the x-axis.

The slope-intercept equation is y=mx+b. This b is the y-intercept. To find the x-intercept, you plug in the value 0 for y and solve for x. This is because the x-axis is the line y=0, so you will see where the x is if y is equal to 0.

Linear equations and functions can be written in slope intercept form (y=mx+b), standard form (Ax+By=C), and point slope form \(y-y_{1} =m(x-x_{1} )\).

They can be graphed by finding the y and x intercepts from the equation and then connecting the points to draw the line!

The rule of obtuse angle is that one angle measures more than 90° and total sum og angle should be 180°.

Acute, obtuse, right, straight, reflex, and complete rotation are some of the terms used to describe fundamental angles. Two rays are joined at their termini to form the geometric shape known as an angle. The most common way to express an angle is in degrees.

A measure of an angle or the amount of turning required to bring one line or plane into coincidence with or parallel to another angled is represented by two lines extending from the same point.

A triangle is said to have an obtuse angle if one of the inner angles is greater than 90 degrees. If one of the angles of an obtuse triangle is greater than 90°, then the total of the other two angles is also less than 90°.

The area of the square is increasing at a rate of 98 cm²/s.

Starting with the formula for the area of a square: A = s², where s is the length of each side, find the rate of change of the area with respect to time (dA/dt), we can use the chain rule of differentiation:

dA/dt = d/dt (s²) = 2s ds/dt

where ds/dt is the rate at which each side is increasing.

We are given that ds/dt = 7 cm/s, and we want to find dA/dt when A = 49 cm².

Since the square has four equal sides, we know that s = √(A).

So when A = 49 cm², we have s = √(49) = 7 cm.

Substituting these values into our formula for dA/dt, we get:

dA/dt = 2s ds/dt = 2(7 cm) (7 cm/s) = 98 cm²/s

Therefore, when the area of the square is 49 cm² and each side is increasing at a rate of 7 cm/s, the area of the square is increasing at a rate of 98 cm²/s.

The percentage strength of neomycin in the final compounded product is approximately 2.5%.

To determine the percentage strength of neomycin in the final compounded product, we need to calculate the weight of neomycin in the cream and divide it by the total weight of the cream.

Neomycin (5%) cream: 30g

The neomycin content is 5% of the total cream weight. To find the weight of neomycin in the cream, we multiply the cream weight by the neomycin percentage:

Weight of neomycin = 30g × 0.05 = 1.5g

Now, to calculate the percentage strength of neomycin in the final compounded product, we divide the weight of neomycin by the total weight of the cream and multiply by 100:

Percentage strength of neomycin = (Weight of neomycin / Total weight of cream) × 100

Percentage strength of neomycin = (1.5g / 60g) × 100 ≈ 2.5

Therefore, the percentage strength of neomycin in the final compounded product is approximately 2.5%.
