b. The probability that the first set is green is = 0.8
c. Probability that the second set is green is = 0.06
d. The probability that both the sets are green is = 0.48
e. The probability that at least one set is green is = 0.86
Define probability?The likelihood that an event will occur is described by probability. There are many circumstances in real life where we may need to foresee how something will turn out. We might be able to predict the outcome of an event or we might not. At this point, we say, "There is a chance that the event will happen or not."
Here in the question,
b.
The probability that the first set is green is:
P = 1 - 0.2
= 0.8
c.
Now the first set is given as not green.
Probability that the second set is green is:
p = 0.2 × 0.3
= 0.06
d.
Now probability that both the sets are green is:
P = 0.8 × 0.6
= 0.48
e.
When both the sets are not green, probability is:
0.2 × 0.7
= 0.14
So, probability that at least one set is green is:
P = 1- 0.14
= 0.86

Rectangle
A = b · h
Triangle
A = 0.5 · b ·h
Where:
A - Areab - Widthh - HeightNow we proceed to determine the surface areas:
Case 1
A = 2 · (4 in) · (5 in) + 2 · (3 in) · (4 in) + 2 · (5 in) · (3 in)
A = 40 in² + 24 in² + 30 in²
A = 94 in²
Case 2
A = 2 · 0.5 · (3 cm) · (4 cm) + (5 cm) · (4 cm) + (5 cm) · (3 cm) + (5 cm)²
A = 12 cm² + 20 cm² + 15 cm² + 25 cm²
A = 72 cm²
Case 3
A = 2 · (3 m) · (7 m) + 2 · (6 m) · (7 m) + 2 · (6 m) · (3 m)

(a) Three squares have the areas of 7 cm², 17 cm² and 10 cm², (i) Will the squares exactly surround a right angled triangle? (ii) Explain your answer.
Answer:
(i) This equation is not true, which means that the three squares cannot exactly surround a right-angled triangle.
(ii) It is not always possible for three squares to surround a right-angled triangle. One way to see this is to note that the side lengths of a right-angled triangle satisfy the Pythagorean theorem, which means that they must be in a certain relationship to each other. On the other hand, the areas of three squares can take any values, so it is not always possible to find three squares whose side lengths satisfy the Pythagorean theorem.
Step-by-step explanation:
To determine whether the three squares can exactly surround a right-angled triangle, we need to use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
Let's assume that the three squares have side lengths a, b, and c, with areas of 7 cm², 17 cm², and 10 cm², respectively. Then, we have:
a² = 7 cm²
b² = 17 cm²
c² = 10 cm²
We need to find out whether there exist values of a, b, and c that satisfy the Pythagorean theorem. If such values exist, then the three squares can surround a right-angled triangle.
We can rearrange the equations above to solve for a, b, and c:
a = √7 cm ≈ 2.65 cm
b = √17 cm ≈ 4.12 cm
c = √10 cm ≈ 3.16 cm
Now, we can check whether the Pythagorean theorem holds:
c² = a² + b²
(√10 cm)² = (√7 cm)² + (√17 cm)²
10 cm = 7 cm + 17 cm
This equation is not true, which means that the three squares cannot exactly surround a right-angled triangle.
In general, it is not always possible for three squares to surround a right-angled triangle. One way to see this is to note that the side lengths of a right-angled triangle satisfy the Pythagorean theorem, which means that they must be in a certain relationship to each other. On the other hand, the areas of three squares can take any values, so it is not always possible to find three squares whose side lengths satisfy the Pythagorean theorem.

because y=3 and x=4
Suppose 15% of x equals 20% of y. What percentage of x is y?
A 5
B 35
C 75
D 133 1/3
E 300
If 15% of "x" is 20% of "y", then "y" is 75 percent of "x", the correct option is (c).
The "Percentage" is defined as a way to express the proportions or rates in terms of a "relative-scale" out of 100,
We know that, 15% of "x" equals 20% of "y".
Mathematically, this can be expressed as,
0.15x = 0.20y, ...because 15% = 0.15 and 20% = 0.20;
To find what percentage of x is y, we need to express "y" as a percentage of "x".
On solving further,
We get,
⇒ 0.15x = 0.20y,
⇒ y = (0.15x)/0.20,
⇒ y = 0.75x
It is read as "y" is read as 75% of "x".
Therefore, "y" is 0.75 times "x", or 75% of "x", Option(c) is correct.

The ratio of the lengths of the corresponding sides of the similar right triangles indicates that the length of the segment [tex]\overline{BD}[/tex] = 8 units
What are similar triangles?Similar triangles are triangles that have the same shape, and therefore, the interior angles of each triangle are congruent to the three angles in the similar triangle, however, the sizes of the triangles may be different.
The similar triangles are; ΔABD, ΔBCD, ΔACB
∠ABD ≅ ∠BCD ≅ ∠ACB (Corresponding angles in similar triangles are congruent)
[tex]\overline{AD}[/tex]/[tex]\overline{BD}[/tex] = [tex]\overline{BD}[/tex]/[tex]\overline{DC}[/tex]

Randy is designing a circular garden that is 18 feet in diameter. He is buying plastic edging that costs $1. 50 per foot. He can only buy edging in whole-foot amounts. How much does it cost Randy to buy edging for his garden? Use 3. 14 for pie.
If the diameter of circular-garden is 18 feet, then it will cost Randy an amount of $85.50 to buy edges for his garden.
The "Circumference" of circle is defined as the "total-length" of the boundary or the outer edge of the circle.
The circumference formula is : Circumference = π × Diameter,
The "diameter" of garden is = 18-feet,
So, Circumference = 3.14 × 18 = 56.52 feet,
Since, Randy needs to buy plastic-edging to cover the entire circumference of garden, he needs to buy 56.52 feet of edging.
We know that, Randy can only buy edging in whole-foot amounts,
So, rounding up to the nearest whole foot, we get 57 feet,
The cost of edging is = $1.50 per foot,
So, "total-cost" for Randy to buy edging for his garden is,
⇒ Total Cost = (Cost per foot) × (Number of feet),
⇒ $1.50 × 57,
⇒ $85.50
Therefore, it will cost Randy $85.50 to buy edging for his circular garden.

[tex]7\sqrt[3]{7}-\sqrt[3]{128}[/tex]
The expression 7∛7 - ∛128 is: 49∛7 - 8∛2.
What is the expression?We can simplify this expression using the fact that ∛(a * b) = ∛a * ∛b and ∛(a^3) = a.
First, let's factor ∛128 into prime factors: ∛128 = ∛(2^7) = 2 * ∛(2^5) = 2 * ∛(32).
Next, we can simplify 7∛7 as much as possible:
7∛7 = ∛(7^3) * ∛7 = 7∛(7^2) * ∛7 = 7 * 7∛7.
Now we can substitute these simplifications into the original expression:
7∛7 - ∛128 = 7 * 7∛7 - 2 * ∛32
We can simplify ∛32 as follows:
∛32 = ∛(2^5) = 2 * ∛(2^2) = 4∛2
Now, we can substitute this back into the expression:
7 * 7∛7 - 2 * ∛32 = 7 * 7∛7 - 2 * 4∛2
= 49∛7 - 8∛2
So the simplified expression is 49∛7 - 8∛2.

Find the equation of the line that is perpendicular to the line AB and passes through the point. (0,2)
The equation of a line perpendicular to line AB and passing through point (0,2) is y = -4x + 2.
The given line has a slope of 1/4, so the slope of any line perpendicular to it will be -4 (the negative reciprocal).
Using the point-slope form of a line, we can write the equation of the line passing through the point (0,2) with slope -4 as
y - 2 = -4(x - 0)
Simplifying, we get
y - 2 = -4x
Adding 2 to both sides, we get

What is law of sines?A trigonometric formula known as the rule of sines connects any triangle's sides and angles. It claims that for all three sides of a triangle, the ratio of the length of one side to the sine of the angle opposite that side is the same. In other words, if a triangle has angles A, B, and C opposing its sides and sides a, b, and c, then:
If a/sin(A) = b/sin(B) = c/sin(C), then
If some of the other sides and angles of a triangle are known, this formula can be used to solve for those unknown sides or angles. However, it is restricted to triangles and calls for the measurement of at least one angle and one side's length.
The situation can be depicted as a right triangle, with building 200 feet, the angle of depression is 30 degrees.
Now,
tan(30) = opposite/adjacent = 200/distance
distance = 200/tan(30) ≈ 115.47 feet

A recent conference had 750 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?
There were about 193 principals in attendance.
There were about 260 principals in attendance.
There were about 557 principals in attendance.
There were about 680 principals in attendance.
The activity with a central angle of 54° is Kayaking and there were about 557 principals in attendance based on the prediction
The activity with a central angle of 54°The formula to calculate the central angle for an activity is:
central angle = (number of campers for the activity / total number of campers) x 360°
Using this formula, we can calculate the central angle for each activity:
Kayaking: (15/100) x 360° = 54°
Wakeboarding: (11/100) x 360° = 39.6°
Windsurfing: (7/100) x 360° = 25.2°
Waterskiing: (13/100) x 360° = 46.8°
Paddleboarding: (54/100) x 360° = 194.4°
Therefore, the activity with a central angle of 54° is Kayaking.
Predicting the number of principals in attendance at the conference?To make a prediction about the number of principals in attendance at the conference, we can assume that the proportion of principals in the exhibit room is similar to the proportion of principals in the whole conference.
In the exhibit room, out of 70 people, 52 were principals.
So, the proportion of principals in the exhibit room was 52/70
We can predict the number of principals in attendance at the conference as follows:
Number of principals = proportion of principals x total number of attendees
If we plug in the values, we get:
number of principals = 52/70 x 750 = 557
So, based on this prediction, we can say that there were 557 principals in attendance at the conference.

The height of the bar for three violations measures out at 1.
Conversely, a measurement of 2 denotes the bar for six infringements.
An assessment of 1 has been given to the bar with regards to eight offences.
Due to the lack of representation mentioned in the histogram concerning both 4 and 5 transgressions, it confirms our inference: nobody from the selection received four or five traffic tickets.
