If Samuel ran for 30 minutes covering 4.5 miles, swim for 20 minutes covering 2/3 miles and biked for 45 min covering 9 miles, then the Samuel's average speed during his morning training is 0.15 miles per minute

The Morning activities of Samuel

He ran for 30 minutes, covering 4.5 miles,

He swim for 20 minutes covering 2/3 miles

He biked for 45 minutes covering 9 miles

Total distance travelled = 4.5+ 2/3 +9

= 14.17 miles

Total time taken = 30+20+45

= 95 minutes

The average speed = Total distance / Total time taken

= 14.17/95

= 0.15 miles per minutes

Hence, if Samuel ran for 30 minutes covering 4.5 miles, swim for 20 minutes covering 2/3 miles and biked for 45 min covering 9 miles, then the Samuel's average speed during his morning training is 0.15 miles per minute

The range of the given data set is 18.

What is range in statistics?
The difference between the highest and lowest values for a given data collection is the range in statistics. As a result, the range may alternatively be thought of as the distance between the highest and lowest observation. The range of observation is the name given to the outcome. Statistics' range reflects the variety of observations. In statistics, we must put the given values, set of data, or set of observations in ascending order in order to determine the range. That indicates that you should start by writing the observations from lowest to highest value. The formula must now be used to determine the range of observations, which is:
Range = Highest Value – Lowest Value = Highest observation – Lowest observation = Maximum value – Minimum Value

Given, the data set is 79, 91, 76, 87, 93, 79,94.
The data in ascending order is : 76, 79, 79, 87, 91, 93, 94.
From the data set, highest value = 94, lowest value = 76
Thus, Range = Highest value - Lowest value = 94 - 76 = 18
Therefore, range of the given data set is 18.

The probability that exactly 4 bulbs from the sample are defective is; 0.2812

The formula for binomial probability distribution is;

P(X = x) = nCx * p^(x) * (1 - p)^(n - x)

p = probability of success

n = number of trials, or the sample size

x = the number of successes in the probability

Now, we are given that;

Sample size; n = 19

Number of successes in the probability; x = 4

probability of success; p = 20% = 0.2

Thus;

P(X = 4) = 19C4 * 0.2^(4) * (1 - 0.2)^(19 - 4)

The inequality is represented by x<40

An inequality compares two values and indicates whether one is lower, higher, or just not equal to the other.

A B declares that a B is not equal.

When a and b are equal, an is smaller than b.

If a > b, then an is bigger than b.

The phrase "a b" denotes that an is less than or equal to b.

When a and b are equal, it is said that an exceeds b.

Since (-3, 2) is its solution which means the graphs of each side are intersected at point (-3, 2)

To verify the solution, substitute x by -3 on each side

If the two sides are equal, then the point is the solution to it

Let us do the same with the right-hand side

L.H.S = R.H.S = 10

This means the value of y = 10, not 2

Then (-3, 2) is not a solution of the given equation

Now we will draw each side, then find the point of intersection between them

From the graph, the solutions are the intersection points between the line and the graph

The two points are (-3, 10) and (2, 5)

The domain of a function is the set of all x-values the function can take.

Since we have a radical symbol, (x² - 1) must not be equal to a negative number because it will make the function undefined.

For the function (x² - 1), the value of x must be greater than 1 or less than -1 in order for the function to be defined.

If for instance, the value of x is 0.5, the value of (x² - 1) will be -0.75 and the square root of a negative number is undefined. Therefore, we must not have an x-value that is less than 1 or greater than -1.

Hence, the domain of this function in interval notation is:

In set notation, it is {x|x ≤ -1, x ≥ 1}.

In order to graph the function, let's assume some values of x that are found in the domain.

For the domain, x ≤ -1, we can assume x = -1, x = -2, and x = -3.

At x = -1, y = 1.

At x = -2, y = 3.73

At x = -3, y = 5.83.

For the domain x ≥ 1, we can assume x = 1, x = 2, and x = 3.

At x = 1, y = -1.

At x = 2, y = -0.268

At x = 3, y = -0.172.

When a molding is randomly selected from the early morning run of a random day, what is the probability that it is defective is 0.1051

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Probabilities can be written as percentages with values between 0 and 1.

From the information, the foreman for an injection-molding firm admits that on 29% of his shifts, he forgets to shut off the injection machine on his line.

The probability that the selected molding is defective will be:

= P(forgets to shut off and defective molding) + P(not fingers to shut off)

= 29% × 24% + (1 - 29%) × 5%

= 0.29 × 0.24 + 0.71 × 0.05

= 0.0696 + 0.0355

Applying the similarity theorem, the value of x is calculated as: x = 3.5.

When two triangles are similar to each other, based on the similarity theorem, the ratio of their corresponding side lengths will be equal because they are proportional to each other.

In the image given, triangle ABC is similar to triangle ADE. Therefore:

AB/AD = BC/DE = AC/AE

Given the following:

AB = 4 units

AD = 4 + 3 = 7 units

The statement which is true about Function A and Function B is that: C. The initial value for Function A is greater than the initial value of Function B.

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope A = (0 - 2)/8 - 0)

Slope A = -2/8

Slope A = -1/4 or -0.25.

Note: The slope of any straight line also represents its rate of change.

Rate of change of Function A = -0.25.

Rate of change of Function B = 4.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (0, 2), we have:

y - 2 = -1/4(x - 0)

y - 2 = -x/4

y = -x/4 + 2.
