Find the value of (-3/8) x (+8/15)

A. -1/5
B. -1/3
C. 11/15
D. 11/23

The equation of line containing vertices (8,4) is y = 4.

Y = mx+b, where m is the slope and b is the y-intercept, is the formula for the slope-intercept form (the point where the line crosses the y-axis). Using y=mx+b to graph a line is typically simple. The standard form and the point-slope form are other formats for linear equations.

Equation of line in slope - intercept form is

y = mx + c

where m= slope

c = y - intercept

As it is given that equation of line is horizontal,

this implies

x = 0

y = m (0) + c

y = c

Now, the given coordinates are (8,4)

Slope of the equation equals 0 As the line is horizontal.

⇒ y = 0 (8) + 4

⇒ y = 4

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.

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

= 0.1051

The probability is 0.1051.

Answer:

109.1 and 70.9 are supplementary angles

Step-by-step explanation:

The measure of an angle is 70.9°. What is the measure of its supplementary angle?

Supplementary angles are two angles that sum together to 180 degrees:

180 - 70.9 = 109.1 degrees

First angle is 3x° = 3 × 40° = 120°

and, Second Angle is = (x + 20°) = 40° + 20° = 60°

Given,

Lines m and n are parallel (m ll n)

Adjacent Interior Angles are given i.e.,

3x and (x + 20°)

and, To find the value of x

Now, According to the question:

m ll n

So, The two lines are parallel and complementary to the

3x° + (x + 20°) = 180° (Adjacent Interior Angles)

4x°+ 20° = 180°

4x° = 180° - 20°

4x° = 160°

x = 40°

Hence, First angle is 3x° = 3 × 40° = 120°

and, Second Angle is = (x + 20°) = 40° + 20° = 60°

Explanation

We are given the following:

We are required to determine the converse, inverse, and contrapositive statements of a conditional statement and also determine whether the statement is true or false.

This is achieved thus:

We know that if P and Q are two simple statements, then

Implication (Conditional): P → Q

Converse: Q → P

Inverse: ~ P → ~ Q

Contrapositive: ~ Q → ~ P

We also know that an implication is false if the antecedent is true and the consequent is false.

Therefore, we have:

ive n statement: I

Let P: A toy block is a clover

Let Q: A toy block is red.

The given statement is true. This is because both statements are true.

Converse: If a toy block is red, then the toy block is a clover.

This statement is false. This is because it is not true for all cases.

Inverse: If a toy block is not a clover, then the toy block is not red.

This statement is true.

Contrapositive: If a toy block is not red, then the toy block is not a clover.

This statement is true.

A number of distinct units of mass, weight, or volume are derived from the uncia, an ancient Roman unit of measurement, including the ounce, which is almost unmodified.

'Ounce' is also used in the following other contexts:

A unit of the force is the ounce-force (see below).

A unit of the volume is the fluid ounce.

A multitude of distinct ounces measuring mass or volume have been employed historically by various trades at various times and in various countries.

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.

Let's plot the 6 coordinates. The graph of this function, with limits indicated, is shown below.

The given limit has its value as 2/3.

The most important calculus rule is known as the L' Hospital's Rule (L'Hôpital's rule). With the help of derivatives, this rule assesses limits involving indeterminate forms. The L'Hospital rule is a general method for evaluating indeterminate forms like∞ / ∞  or /. Calculus derivatives' limits for indeterminate forms are determined using L'Hospital's rule. The L Hospital rule can be applied numerous times.

This guideline recommends differentiating the numerator and denominator by an equal number of times until the confusing or problematic phrase is eliminated for easy understanding.

Since the limit is of the 0/0 type when both the numerator and denominator have h=0, the L Hospital rule can be applied in this situation.

Once the numerator has been differentiated, we obtain Numerator = 2((1/3) + h)

Once the denominator has been differentiated, we obtain Denominator = 1.

As a result of the denominator's complicated factor being eliminated, the limit can now be set.

As a result, the limit at h = 0 has a value of = 2((1/3) + 0)]/1 = 2/3.

As a result, when h=0, the value of the stated limit is 2/3.

Since the given equation is

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)

Explanations:

8 - ( -3d + 2)

Open up the brackets:

The negative (-) sign outside the bracket will multiply both -3d and 2 one by one.

The equation then becomes:

8 + 3d - 2

Collect like terms:

8 and 2 are similar, they can come together. The equation becomes

8 - 2 + 3d

Note that 3 is a common factor of 6 and 3, the equation finally becomes:
