Answer:

1,730

Step-by-step explanation:

173x10 (pieces)= 1730

A linear function is a function in which we add multiple of a constant.

Given data:

We have

Clearly, we have add multiples of 480 to 18,250.

So, the given function represents a linear function.

So, the correct option is (a).

Based on the lengths of the sides of the triangle, we can infer that this is NOT a right triangle.

A right angled triangle would obey the Pythagoras Rule which is that the square of the hypotenuse (longest side) will be the sum of the squares of the other sides of the triangle.

This means that for this to be a right triangle, it needs to obey the function:

45 ² = 35 ² + 30 ²

Solving gives:

2,025 ≠ 2, 125

This shows that the triangle is not a right triangle.

It is not a right-angle triangle since 2125 ≠ 2025 meant that it did not conform to Pythagoras' theorem's specifications.

This kind of query creates a right-angled triangle that Pythagoras' theorem can resolve.

In a right-angled triangle, the square of the greatest side is equal to the sum of the squares of the smaller two sides.

Given, There are three sides to a triangle, each measuring 30 kilometers, 35 kilometers, and 45 kilometers.

∴ 30² + 35² = 45².

900 + 1225 = 2025.

2125 ≠ 2025.

Due to the fact that it didn't meet the requirements of Pythagoras' theorem, it is not a right-angle triangle.

Answer:

Step-by-step explanation:

two angles are a linear pair, and one has twice the measure of the other. Find the smaller angles measure

linear pair = 180°

180 : 3 = 60° (smaller angle)

60° x 2 = 120° (bigger angle)

120 is twice 60 and the sum is 180°

A forest is decreasing in size by 60 hectares every 3 years. In 7 years, the forest will have decreased by 140 hectares.

Using the Unitary Method:

∵ In '3' years, a forest decreased in size by '60' hectares

∴ In '1' year, a forest will be decreased in size by '20' hectares

Every year 20 hectares is decreased. Considering a regular trend in the decrement of forest area, the time span of '7' years will diminish 'to 140' hectares.

Three pairs of siblings from different families can be seated in two rows of three chairs so that siblings may not sit next to each other in the same row, and no child may sit directly in front of their sibling in 96 ways.

There are 3 pairs of siblings. We can name them as a₁, a₂, b₁, b₂, c₁ and c₂, a total of 6 children.

There are 2 rows of 3 seats each.

We will try to find the number of ways each seat can be filled.

So considering the first seat in first row, it can be filled in 6 different ways. Because any one from 6 children, say a₁, can be seated.

Now for the second seat in first row can only be filled by one of b₁, b₂, c₁ or c₂ because the first seated child a₁ along with the sibling a₂ of the same cannot be seated in the second seat. So in 4 different ways.

For the third seat remaining in the first row, one out of the remaining  pair of siblings c₁ or c₂ can be seated. This can be done in 2 ways.

Now after filling the first row in this manner, the second row can be filled in only 2 ways.

So total number of ways the children can be seated = 6 x 4 x 2 x 2 = 96 ways

This Question involves the concept of Solving Simulteanous Equations.

Simulteanous Equations are 2 sets of equation with 2 unknownes to solve. Methods used are Substitution and Elimination methods, use either to solve unless question specify a method.

Example:

2x + 4y = 67

3x + 9y = 90

We are given the 2 equations:

y = 2x - 1 (Equation 1)

2x + y = 3 (Equation 2)

We are asked to use the Substitution Method.

We first substitute Equation 1 to Equation 2 to find the value of x.

2x + (2x - 1) = 3

2x + 2x - 1 = 3

4x - 1 = 3

4x = 3 + 1

4x = 4

x = 4 ÷ 4 = 1

Now we can substitute x into Equation 1 to find the value of y.

y = 2(1) - 1

Given a sample of the size, measured in square feet, of 17 faculty offices.

1) Mean

To calculate the mean of the sample you have to add all observations of the data set and divide it by the sample size:

The mean square footage is 131.5 ft²

2) Median

To determine the median of the data set, first, you have to calculate the position of the median, following the formula:

The sample size is n=17, then the position of the median is

The median corresponds to the ninth observation of the data set.

Next, you have to order the data set from least to greatest:

The measure of the angle is calculated using the attached figure.

What is an angle?

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction. Angle can also refer to the measurement of an angle or of a rotation. This measurement is the length of a circular arc divided by its radius. The arc is centered at the vertex in the case of a geometric angle.

From figure,

angle x = 180° - 110° = 70° (linear pair)

angle y = 37° (alternate interior angles)

Measure of angle 1 = 70° + 37° (exterior angle in a triangle is equal to the sum of opposite interior angles)

Answer:

Step-by-step explanation:

You have 15 pencils in your pencil case.1/5 of the pencils are green. How many are not green?

= 1 - 1/5

= 5/5 - 1/5

= 4/5

This means that 4/5 of the 15 pencils are not green. So:

4/5 * 15 = 12 pencils are not green.

Answer:

  A: 15%

  B: 43%

  C: yes

Step-by-step explanation:

You want the percentages of students who failed the exam, given that they (A) did, or (B) did not complete the exam review. You also want to know if this indicates an association between failing and reviewing.

Let F represent the event "failed the exam." Let R represent the event "completed the exam review." R' will be the event "did not complete the review."

The probability is ...

  P(F|R) = P(F&R) / P(R)

  P(F|R) = 0.10/0.65 = 2/13 ≈ 15%

About 15% failed who completed the review.

  P(F|R') = P(F&R') / P(R')

  P(F|R') = 0.15/0.35 = 3/7 ≈ 43%

About 43% failed who did not complete the review.

If the events "Failed the exam" and "Completed the review" were independent, then the probability of one would not be conditional upon the other. Here, the probability of failing is clearly different for those who completed the review, so there is an association between failing the exam and completing the exam review.
