Two rectangles have the exact same area.The measurements of the first rectangle is 3k by 3.Calculate the value of k
Answers
In the area of the rectangle the value of the k is 6.
According to the statement
We have to find that the value of the k in the area of rectangle.
So, For this purpose, we know that the
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
From the given information:
Two rectangles have the exact same area.The measurements of the first rectangle is 3k by 3 and the measurements of the second rectangle is k+3 by 6.
Then
The area of the first rectangle = 3k*3
The area of the first rectangle = 9k
And
The area of the second rectangle = 6(k+3)
The area of the second rectangle = 6k+18
Then
Compare the both values of the area
6k+18 = 9k
9k - 6k = 18
3k = 18
k = 18/3
k = 6.

a) draw a density curve to model the amount of time that Jayden has to wait for the bus. Be sure to include scales on both axes.
b) on what percent of days does Jayden wait more than 7 minutes for the bus?
c) find the 38th percentile of this distribution.
Answers
Using the uniform distribution, we have that:
a) The graph is given at the end of the answer.
b) Jayden waits more than 7 minutes 30% of the days.
c) The 38th percentile is of 3.8 minutes.
What is the uniform probability distribution?It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
For this problem, the bounds are given as follows:
a = 0, b = 10.
As shown in the graph at the end of the answer.
The probability of waiting more than 7 minutes is:
[tex]P(X > 7) = \frac{10 - 7}{10 - 0} = 0.7[/tex]
Jayden waits more than 7 minutes 30% of the days.
The 38th percentile is x for which P(X < x) = 0.38, hence:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
0.38 = x/10
x = 3.8.

A family plans to have 3 children. For each birth, assume that the probability of a boy is the same as the probability of a girl. What is the probability that they will have at least one boy and at least one girl?.
Answers
Probability of having at least one boy and at least one girl is 0.75
There are two possibilities of a child, it could be a girl or a boy.
Since, the family plans to have 3 children.
∴ Total outcomes are = 2³
Total outcomes are = 8 outcomes
The total possible outcomes are: BBB, BBG, BGB, GBB, GBG, BGG, GGB, GGG
So, there are 8 possible outcomes.
Now, probability of having at least one boy and at least one girl= 1 - (Probability of having all girls, Probability of having all boys)
Probability of having all girls i.e., GGG = 1/8
Probability of having all boys i.e., BBB = 1/8
P(at least one boy and at least one girl) = 1 - (1/8 + 1/8)
= 1 - (2/8)
= 6/8
= 0.75
∴ P(at least one boy and at least one girl) = 0.75

The mass ratio of the rocket is 10.8468 kg/C.
What is mass ratio of a rocket?An indicator of a rocket's effectiveness is its mass ratio. It describes the ratio of the rocket's wet mass to its dry mass, or how much more massive the vehicle is with propellant than without.Given:
v = - 0.0098(t) + c (ln (R) ), where:v = maximum shuttle velocityt = firing timec = velocity of exhaustR = mass ratioHere, c = 3.1 km/s, t = 50s, v = 6.9km/sTo find: Mass ratio (R) = ?
Finding:
On substituting the values of 'c', 't', 'v', we get:
6.9 = - 0.0098 (50) + 3.1 (ln (R) )
=> 6.9 + 0.49 = 3.1 (ln (R) )
=> 7.39 = 3.1 (ln (R) )

As A and B are vertical angles, the measures of angle A and B is 98° each.
What in geometry are Vertical Angles?When two lines collide, vertical angles are created. The angles that are directly opposite one another, out of the four that are generated, are vertical angles. Additionally, they are known as "vertically opposed angles." All of these angles are equal.
Vertical angles are created when two straight lines cross. Angles vertically are consistently congruent and equal. As the two sets of non-adjacent angles created by crossing two lines superimpose on one another, vertical angles are congruent.
As A and B are vertical angles,

Answers
Answer:
g(x) = | x + 5 | + 2
Step-by-step explanation:
given f(x) then f(x ± h ) represents a horizontal translation of f(x)
• if x > 0 then a shift to the left of h units
• if x < 0 then a shift to the right of h units
here f(x) is shifted left by 5 units , then
g(x) = | x + 5 |
given f(x) then f(x) + k represents a vertical translation of f(x)
• if k > 0 then a shift up of k units
• if k < 0 then a shift down of k units
here f(x) is shifted up 2 units , then

Answers
The probability that at least one ball of each color is chosen is 105/8568.

Number of red balls in the urn = 5
Number of white balls in the urn = 6
Number of blue balls in the urn = 7
We have to find the probability that at least one ball of each color is chosen.
Let us consider the that 1 ball of each color has been chosen.
Hence, we are left with 4 red balls, 5 white balls and 6 blue balls.
Now we have to choose 2 balls from them.
Hence,
Number of ways in which we can choose 2 balls from (4+5+6) that is 15 balls = [tex]^{15}C_2=105[/tex]
Total number of ways in which we can choose 5 balls from 18 balls =

What is Newton's Third Law of Motion?Newton's Third Law of Motion states that for every action there is an equal but opposite reaction. This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.
Next, we would determine the resultant forces in the two scenarios as follows:
Resultant force A = Forward force - Wind force
Resultant force A = 15 N - 10 N
Resultant force A = 5 Newton.
Resultant force B = Upward force - Force of gravity
Resultant force B = 10 N - 5 N
Resultant force B = 5 Newton.
