There are 4 green crayons, 6 yellow crayons and 3 blue crayons. P(green
then blue) without replacement. *
Answer:
0.0769 or 7.69%
Step-by-step explanation:
Number of green crayons = 4
Number of yellow crayons = 6
Number of blue crayons = 3
Total number of crayons = 4 + 6 + 3
= 13 crayons
[tex]Probability=\frac{\text{favorable outcome}}{\text{total number of outcome}}[/tex]
probability to get first green crayon P₁ = [tex]\frac{4}{13}[/tex]
Probability to get second crayon is blue P₂ = [tex]\frac{3}{12}[/tex]
P = P₁ × P₂
= [tex]\frac{4}{13}\times \frac{3}{12}[/tex]
= [tex]\frac{12}{156}[/tex]
= 0.0769
Probability to get green then blue is 0.0769 or 7.69%

What is the area of ACDE to the nearest whole number? 10 cm 20 cm 21 cm А A 87 cm B. 105 cm C. 123 cm D 210 cm
The area of ACDE is 205 cm^2.
Explanation:The area of ACDE can be determined by finding the area of triangle ACD and triangle ADE and then summing their areas.
To find the area of triangle ACD, we can use the formula Area = 1/2 * base * height. In this case, the base is AD which is 21 cm and the height is 10 cm. Substituting these values into the formula, we get Area_ACD = 1/2 * 21 cm * 10 cm = 105 cm2.
Next, to find the area of triangle ADE, we can use the same formula. The base is DE which is 10 cm and the height is AC which is 20 cm. Substituting the values, we get Area_ADE = 1/2 * 10 cm * 20 cm = 100 cm2.
Finally, we add the areas of ACD and ADE to get the total area of ACDE: Area_ACDE = Area_ACD + Area_ADE = 105 cm2 + 100 cm2 = 205 cm2.

The calculated area of the trapezoid ACDE is 123 square cm
How to determine the area of ACDEFrom the question, we have the following parameters that can be used in our computation:
The figure
Where, we have
BE² = 20² - 10²
This gives
BE² = 300
So, we have
BE = 17.3
This means that
CD = 21 - 17.3
CD = 3.7
The area of ACDE is calculated as
Area = 1/2 * (AE + CD) * AB
This gives
Area = 1/2 * (21 + 3..7) * 10
Evaluate
Area = 123
Hence, the area of ACDE is 123 square cm

At a tennis event, 10% of a player's score is based on serves, 40% on return balls, and 50% on wins.
Kyle makes 85% of his serves, returns 70% of the balls, and wins 75% of his games.
What is Kyle's score at the tennis event?
Answer:
74 % score
Step-by-step explanation:
Player score = 10% * (S) + 40%*(R) + 50%*(W)
S = serves
R = return balls
W= wins
S = .85
R = .7
W = .75
Player's score = 0.1* 0.85 + 0.4 * 0.7 + 0.5*(0.75)
Player's score = 0.085 + 0.28 + 0.375 = 0.74 = 74%
The Score is 74%

Which of the following statements is true regarding a representative sample?
A.
It is at least 1/2 of the total population.
B.
It focuses on a specific group within the population.
C.
It is a group that is fairly proportional to the population.
Answer:
B
Step-by-step explanation:
The following statement is true regarding a representative sample
"It is a group that is fairly proportional to the population".
What is the representative sample?
A representative sample is a subset of a population that is selected in such a way that it accurately reflects the characteristics of the entire population. The goal of a representative sample is to ensure that the sample is as representative as possible of the population as a whole so that the results of a study based on the sample can be generalized to the population.
A representative sample is not necessarily at least 1/2 of the total population (Option A) or focused on a specific group within the population (Option B). It is simply a group that is fairly proportional to the population, meaning that it contains a similar mix of characteristics as the population as a whole.
Hence, the correct answer would be an option (C).

A manufacturer knows that 2%2\% 2% 2, percent of its microchips are produced with a certain defect. They decide to change their process to make it more efficient, and they want to test if the new process has the same defect rate or not.
Answer: 0.0776
Step-by-step explanation:
Since the manufacturer knows that 2% of its microchips are produced with a certain defect. Then
P( defective) = 2/100 = 0.02
P( non defective) = 1 - 0.02 = 0.98
Probability of all 4 not defective will be
P(all 4 not defective) = 0.98^4 = 0.9224
Probability that at least one of the selected chip is defective will be
P(at one defective) = 1 - 0.9224

C. 4.7 units
D. 9.3 units
The length of the chord of the circle is VI = 9.3 units
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the circle be represented as O
Now , the center of the circle is C
And , the two chords of the circle are AR and VI
where the length of the chord CR = 9.3 units
The chords are separated by a distance ( 4.7 + 4.7 ) units = 9.4 units
So , the chords are congruent or equal in distance
Hence , the chord VI = 9.3 units
