Answer:

Between 30 and 33 mph or, simply

Range: [30,33]

Step-by-step explanation:

A Range is all possible values of a certain variable or piece of information commonly notated by a minimum and maximum. In this example, our variable is the speed traveled by drivers in a road. We are provided a minimum of 30 mph as this is the speed limit, and told that drivers may speed up to a maximum of 3 mph faster ( or 33 mph).

Therefore, our minimum would be 30, maximum would be 33, and Range would be [30, 33].

Brackets are used here because both our minimum and maximum values are included in the range.

One of the key points for two figures to be similar is that the angles are the same.

Since parallelograms have opposite angles equal, and adjacent angles sum up to give 180 degrees. We know that ABC

Angle = 180 - 523 = 127

And this makes the similarity makes the order of similarity here to be

BCD = EFGH

The value of h is 13.3 cm

Let the triangle be ABC where

AB = 18 cm

AC = h cm

∠ABC = 48°

Since, ∠ACB = 90°, therefore the given triangle is a right angle triangle.

We know that

Sinθ = Perpendicular / Hypotenuse

Put θ = 48, we get

Sin 48 = [tex]\frac{h}{18}[/tex]

The value of Sin 48 is 0.74

0.74 × 18 = h

If Jacob ran 10 miles in 80 minutes at that he will run the distance of 18.75 miles in [tex]2\frac{1}{2}[/tex] hours

Number of miles that Jacob will run in 80 minutes = 10 miles

Number of miles that Jacob will run in 1 minutes = Number of miles that Jacob will run in 80 minutes/ 80

= 0.125 miles

We know,

1 hour = 60 minutes

[tex]2\frac{1}{2}[/tex] hours = 2.5×60

The maximum value of P = 11.

Given: P = -x + 6y

In this question we have to first solve the given system of equations.

Ignore the greater or lesser than sign that is:

y = -2x+ 4 -------- 1

And y = x + 1 ---------  2

On solving these two equations we get;

0= -3x + 3

⇒ -3x = -3

⇒ x= 1

Substituting the value of x in equation 2 we get

y = x+ 1

= 1 + 1 = 2

Thus y = 2 and x = 1

So on putting these values in P = -x + 6y we get

P = - 1 + 6× 2

P = - 1 + 12 = 11

Therefore P= 11.

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.

Answer:

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

y = 1.5x - 7            m = 1.5     b = -7

What is linear equations?
Linear equations are a subset of first order equations. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.

How to Solve?
Solving a linear equation involves determining the answer to a linear equation with one, two, three, or more variables. The answer to a linear equation is the value or values of the variable(s) that are part of the equation. There are six main ways to resolve linear equations. For the purpose of solving linear equations, these methods include the Graphical Method, Elimination Method, Substitution Method, Cross Multiplication Method, Matrix Method, and Determinants Method.

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.

His answer of 4x² - 9 is incorrect.

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.

[tex]\textsf{Decimal form}: \quad x=1.312\; \sf (3\:d.p.)[/tex]

Step-by-step explanation:

Given equation:

[tex]\ln x + \ln (x+14)=3[/tex]

[tex]\textsf{Apply the product law} \quad \ln x + \ln y=\ln xy:[/tex]

[tex]\implies \ln (x(x+14))=3[/tex]

[tex]\implies \ln (x^2+14x)=3[/tex]

[tex]\textsf{Apply the log law} \quad e^{\ln x}=x:[/tex]

[tex]\implies e^{\ln (x^2+14x)}=e^3[/tex]

[tex]\implies x^2+14x=e^3[/tex]

Subtract e³ from both sides to form a quadratic equation:

[tex]\implies x^2+14x-e^3=e^3-e^3[/tex]

B) only mean because if we replace 32 by 16 sum will decrease and so mean will decrease

C) both mean and median because when we remove some value os starting total sum will decrease and hence mean decrease

d)Negative skewed

Measures of central tendency are the values that characterize a data set by indicating the data's central location. Mean, Median, and Mode are the three primary metrics for determining central tendency.Mean is the product of the sum of all observations and the total number of observations.

An ordered set's median is its middle or centre value.

The most frequent value in a data set is called the mode.

Given that :32, 38, 42, 42, 43, 44, 46, 46, 47, 47, 49, 49, 51, 51, 51, 51, 52, 53, 53, 53, 53, 53

32, 38, 42, 42, 43, 44, 46, 46, 47, 47, 49, 49, 51, 51, 51, 51, 52, 53, 53, 53, 53, 53

mean = [tex]\frac{sum of observation}{number of observation}[/tex]

mean = [tex]\frac{1046}{22}[/tex]

= 47.54

The median is calculated by sorting the scores into numerical order, dividing the total by two, rounding the result up to get the median position, or using an even number of scores, averaging the median position's value with the following position's value.

here n = 22 which is even

median =[tex]\frac{\frac{n}{2}term +(\frac{n}{2}+1 )term }{2}[/tex]

[tex]\frac{\frac{22}{2}term +(\frac{22}{2}+1 )term }{2}\\ = \frac{11 term + 12 term}{2}[/tex]

= 49

Organize the numbers in a set in whatever order—from lowest to highest or highest to lowest—and then tally the frequency with which each number appears in the group. The mode is the one that shows up most frequently.

mode = 53 as it is repeated more times.

A) none of these
