Answer:

The time taken before the police force the robbers off the road is 1.5 hours

Step-by-step explanation:

The speed with which the robbers were travelling = 70 miles per hour

The speed with which the police went after the robbers = 90 miles per hour

The distance with which the robbers were in front of the police before the police came after them =  miles

Let t represent the time in hours the police force the robbers off the road, we have;

30 + 70 × t = 90 × t

30 = 90 × t - 70 × t = (90 - 70) × t = 20 × t

30 = 20 × t

20 × t = 30

t = 30/20 = 1.5

t = 1.5 hours

The time taken before the police force the robbers off the road = t = 1.5 hours

Answer:

The time taken before the police force the robbers off the road is 1.5 hours

There are two types of scales: nominal scale and ordinal scale.

Nominal scales are named scales where variables are simply "named" or labeled in no particular order. Ordinal scales go beyond mere naming to include all variables in a specific order. Interval scales provide the label, order, and specific spacing between each variable option.

This measurement level classifies data using alphanumeric characters or names. For example, if gender is the variable, the answer is male or female. Ordinal:

Ordinal level variables have the following meaningful order: B. rank

An ordinal scale is a measurement scale that assigns values ​​to objects based on their ranking with respect to each other. For example, a doctor might use a 0 to 10 scale, ranging from 0 (no improvement) to 10 (condition disappeared) to indicate the degree of improvement in the condition.

You are c) a structure. A structure is a collection of one or more different types of variables, including arrays and pointers, that have been grouped under a single name for each manipulation.

A structure is a user-defined data type that allows you to group together related data. For example, you could create a structure to store the name, age, and address of a person. The structure would have three variables, each of a different type: a string variable for the name, an integer variable for the age, and a string variable for the address.

The advantage of using a structure is that it allows you to treat the related data as a single unit. This makes it easier to manipulate the data and to pass the data to functions.

The other answer choices are incorrect. A template is a blueprint for creating a generic class or function. An array is a collection of elements of the same type. Local variables are variables that are declared within a function and that are only accessible within the function.

The integral of f(x) from 1 to 4 is 6.7.

To solve this problem, we can use the property of integrals known as additivity. This states that if we have a function f(x) and we split up its integral into two separate intervals, say from a to b and from b to c, then the integral of f(x) over the entire interval from a to c is equal to the sum of the integral of f(x) from a to b and the integral of f(x) from b to c.
Using this property, we can write:
∫1 to 5 f(x)dx = ∫1 to 4 f(x)dx + ∫4 to 5 f(x)dx
We know that ∫1 to 5 f(x)dx = 10 and ∫4 to 5 f(x)dx = 3.3, so we can substitute these values in and solve for ∫1 to 4 f(x)dx:10 = ∫1 to 4 f(x)dx + 3.3
Simplifying this equation, we get:
∫1 to 4 f(x)dx = 6.7
Therefore, the integral of f(x) from 1 to 4 is 6.7.

Answer:

52%

Step-by-step explanation:

The experimental probability of landing on tails is 52%. This is calculated by dividing the number of times tails was flipped (104) by the total number of flips (200). The probability is expressed as a percentage, so you would multiply the decimal result by 100%.

Here's the calculation:

104 / 200 = 0.52

0.52 x 100% = 52%

So the experimental probability of landing on tails is 52%.

The solution of the standard quadratic equation \(ax^2+bx+c=0\) has solution

\(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

Applying the above principle

\(\Rightarrow x=\dfrac{15.7\pm\sqrt{(-15.7)^2-4(-1.3)(-44.2)}}{2(-1.3)}\\\\\Rightarrow x=\dfrac{15.7\pm\sqrt{246.49-229.84}}{-2.6}\\\\\Rightarrow x=\dfrac{15.7\pm \sqrt{16.65}}{-2.6}\\\\\Rightarrow x=\dfrac{15.7\pm 4.08}{-2.6}\\\\\Rightarrow x=-7.60,\ -4.47\)

2 positive unit tiles is needed

Step-by-step explanation:

Given the expression x^2 – 3x – 10, the partial factorization is as shown;

x^2 – 3x – 10

=  x^2 +2x – 5x – 10

= x(x+2)-5(x+2)

= (x-5)(x+2)

Note that negative values are represented as tiles labelled below (negative tiles) while positive values are tiles labelled above (positive tiles)

From the second line we can see that first term 1 is labeled + x squared, second is labelled +2x (two positive tiles above), then the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative.

Hence base on the partial factorization and the underlined statement, we can see that 2 positive unit tiles is needed to complete the factorization

Step-by-step explanation:

Answer:

Step-by-step explanation:

Finding the line that best matches the provided points using linear regression is one method for solving this issue. A line's equation is denoted by the formula y = mx + b, where m denotes the slope and b the y-intercept.

Use the following formula to get the slope:-

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

where any two points on the line (x1, y1) and (x2, y2) are. Using the points (0, 12) and (7, 19) as our examples:-

m = (19 - 12) / (7 - 0) = 1

Hence, the line's slope is 1.

We may apply the formula: to determine the y-intercept.

b = y - mx

where any point along the line is (x, y). As an example, consider (0, 12):-

b = 12 - 1(0) = 12

Hence, 12 is the y-intercept.

Thus, the following is the equation for the line passing through the indicated points:-

y = x + 12

The last two points, (12, 24) and (15, 27), may now be verified to see if they also lie on this line:

Since (12, 24) is equal to 24 and 12 plus 12, it is on the line.

For (15, 27), the answer likewise sits on the line since 27 = 15 + 12.

Thus, the mathematical formula for the specified positions is y = x + 12.

Answer:

∠ 3 = 110°

Step-by-step explanation:

The measure of the tangent- chord angle is half the the measure of its intercepted arc.

intercepted arc = 360° - 140° = 220°

∠ 3 = 0.5 × 220° = 110°

The measure of angle 3 is 110 degree.

A line that touches a circle or an ellipse at just one point is said to be tangent in geometry. Assuming a line contacts the curve at P, "P" is referred to be the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve.

We have,

Arc= 140

As, The tangent-chord angle's measurement is equal to half of its intercepted arc's measurement.

So, the intercepted arc

= 360° - 140°

= 220°

Now, <3 = 1/2 × 220° = 110°

Thus, the measure of angle 3 is 110 degree.

Step-by-step explanation:

gas mileage = miles covered/gallons used

but:

miles covered = \(35\frac{1}{2}\)

                        = 35.5

gallons used     = 1\(\frac{1}{2}\)

                           = 1.5

gas mileage = 35.5/1.5

gas mileage = 23.667 miles/gallon (to 3 decimal places)

gas mileage = miles covered/gallons used

but:

miles covered = \(27\frac{1}{5}\)

                        = 27.2

gallons used     = \(\frac{4}{5}\)

                         = 0.8

gas mileage = 27.2/0.8

gas mileage = 34 miles/gallon

c)

gas mileage of blue: 23.667 miles/gallon implies the blue car will travel 23.667 miles on 1 gallon

gas mileage of silver: 34 miles/gallon implies the silver car will travel 34 miles on 1 gallon

Hence the silver car would travel a greater distance on 1 gallon than the blue car.
