The diagram below shows the contents of a jar from which you select marbles at random.
An illustration of a jar of marbles is shown. Four of the marbles are labeled with an upper R, seven of the marbles are labeled with an upper B, and five of the marbles are labeled with an upper G. The key identifies upper R to represent red marbles, upper B to represent blue marbles, and upper G to represent green marbles.
What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your work.
What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? Show your work.
Are the answers to parts (a) and (b) the same? Why or why not?
Answers
Answer:
A:
probability of red = 4/16 = 1/4
prob(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) your decision
Step-by-step explanation:
i took the test
The solution is,
A. 7/64 is the probability of selecting a red marble, replacing it, and then selecting a blue marble.
B. 7/60 is the probability of selecting a red marble, setting it aside, and then selecting a blue marble.
C. the answer is no.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given,
There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.
A:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability of red = 4/16 = 1/4
probability(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) obviously,
7/64 ≠ 7/60
So the answer is no.

For the Celsius temperature given, determine the corresponding Fahrenheit temperature. Use the formula t℃=(32+1.8t)℉ for any rational number t. what is the answer
Answers
Answer:
50°F
Step-by-step explanation:
Given the equivalent celcius and Fahrenheit temperature relation :
t℃=(32+1.8t)℉
t = any rational number :
Taking a rational number, t = 10
The Fahrenheit temperature obtained will be :
t°C = 10
t℃=[32+1.8(10)] ℉
10°°C = (32 + 18)°F
The equivalent Fahrenheit temperature = 50°F

logarithm with base 4:

Answers
Answer:
log_4(256)=4
log_4(1/1024)=-5
log_4(16)=2
log_4(1/256)=-4
Step-by-step explanation:
We want to write a number, x, such that
Log_4(y)=x.
In exponential form that is 4^x=y.
So first number is x=4.
4^4=256 which means log_4(256) is 4 as a logarithm with base 4.
The second number is x=-5.
4^-5=1/4^5=1/1024 which means log_4(1/1024) is -5 as a logarithm with base 4.
The third number is x=2.
4^2=16 so log_4(16) is 2 as a logarithm with base 4.
The fourth number is x=-4.
Since 4^4=256 then 4^-4=1/256 which means -4 as a logarithm with base 4 is log_4(1/256).
The logarithmic expressions are: [tex]\log_4(256) = 4[/tex], [tex]\log_4({4^{-5}}) = -5[/tex], [tex]\log_4({16) = 2[/tex] and [tex]\log_4({4^{-4}) = -4[/tex]
A number x written in logarithm form is represented as:
[tex]\log_b(y)=x.[/tex]
Where:
[tex]b^x=y[/tex]
Given that the base is 4, the equations become:
[tex]\log_4(y) = x[/tex]
[tex]4^x = y[/tex]
For number 4, we have:
[tex]y = 4^4[/tex]
[tex]y = 256[/tex]
This gives
[tex]\log_4(256) = 4[/tex]
For number -5, we have:
[tex]y = 4^{-5}[/tex]
This gives
[tex]\log_4({4^{-5}}) = -5[/tex]
For number 2, we have:
[tex]y = 4^{2}[/tex]
[tex]y =16[/tex]
This gives
[tex]\log_4({16) = 2[/tex]
For number -4, we have:
[tex]y = 4^{-4}[/tex]
This gives
[tex]\log_4({4^{-4}) = -4[/tex]
Hence, the logarithmic expressions are: [tex]\log_4(256) = 4[/tex], [tex]\log_4({4^{-5}}) = -5[/tex], [tex]\log_4({16) = 2[/tex] and [tex]\log_4({4^{-4}) = -4[/tex]

The width of a rectangle measures (8.1g-6.5)(8.1g−6.5) centimeters, and its length measures (4.7g-9.2)(4.7g−9.2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answers
Answer:
P = (25.6g - 31.4)
Step-by-step explanation:
Given that,
The width of a rectangle = (8.1g−6.5) cm
The length of a rectangle, = (4.7g−9.2)
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
Substitute all the values,
P = 2(8.1g−6.5+4.7g−9.2)
= 2(12.8g-15.7)
= 25.6g - 31.4
So, the perimeter of the rectangle is equal to (25.6g - 31.4).

Area of the composite figure = Area of rectangle A + Area of rectangle B + Area of rectangle C
= (3 × 4) + (n ×2) + (2 × 3)
