Answer: 5.04x[tex]10^{4}[/tex] particles
in your situation is choose : A
Step-by-step explanation:
the volume of the living room is 1,400[tex]m^{3}[/tex], and there are 3.6 x [tex]10^{1}[/tex] particles of dust / [tex]m^{3}[/tex]
we will convert the room volume to scientific notation = 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex]
then, the total number of particles will be the product of the two numbers, which is 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex] times 3.6 x [tex]10^{1}[/tex] particles/[tex]m^{3}[/tex] = 5.04x[tex]10^{4}[/tex] particles
Which two expressions have the same value?
1. 23-82
2. 23 - (8 x 2)
3. (23 -8) x 2
Answer:
Any expression doesn't have the same value
Step-by-step explanation:
1. 23-82Subtract 82 from 23.
−59
2. 23 - (8 x 2)Simplify each term.
Multiply 8 by 2.
23−1⋅16
Multiply −1 by 16.
23−16
Subtract 16 from 23.
7
3. (23 -8) x 2Subtract 8 from 23.
15⋅2
Multiply 15 by 2.

Which equation shows a correct relation for triangle RSQ?
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

the length of the Boston Marathon is about 26 miles. A mile is equal to 1.609 kilometers. How many kilometers does a runner cover if he or she completes in the race
Answer:
41.834
Step-by-step explanation:
The complete length of the boston marathon is 26 miles
A mile is 1.609 kilometers
Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows
= 26 × 1.609
= 41.834
Hence the runner needs to run 41.834 kilometers

Ayden earned a grade of 89% on his multiple choice history final that had a total of
200 problems. How many problems on the final exam did Ayden answer correctly?
Answer:
178
Step-by-step explanation:
Method 1: Set up a proportion
Set up an equation of the form:
\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=
whole
part
=
\,\,\frac{\color{blue}{\text{percent}}}{100}
100
percent
Assign the variable xx to the unknown value:
\color{red}{x}=
x=
\,\,\color{red}{\text{part}}
part
The question asks what \textit{part}part of the total questions is 89%
Substitute the known values with the numbers given in the problem, and the unknown value with xx:
\frac{\color{red}{x}}{\color{orange}{200}}=
200
x
=
\,\,\frac{\color{blue}{89}}{100}
100
89
Solve for xx:
100\cdot\color{red}{x}=
100⋅x=
\,\,\color{orange}{200}\cdot\color{blue}{89}
200⋅89
Cross multiply
\frac{100x}{100}=
100
100x
=
\,\,\frac{17800}{100}
100
17800
Divide both sides by 100
178
Simplify
Method 2: Convert to decimal and multiply
{89}{100}=0.89
89%=
100
89
=0.89
Move decimal 2 places to the left
{Multiply result by the total:}
Multiply result by the total:
0.89{200}=

The sample space of a random experiment is {a, b, c, d, e, f}, and each outcome is equally likely. A random variable is defined as follows:
Outcome a b c d e f
X 0 0 1.4 1.4 2 3
Determine the probability mass function of X. Use the probability mass function to determine the following probabilities.
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
Answer:
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6 ;
0 ;
1/2 ;
0 ;
2/3 ;
1/2
Step-by-step explanation:
Each has the same probability ;
X ___ : 0 ___ 0 ___ 1.4 ____1.4 ___ 2 ___ 3
P(x) __ 1/6 __1/6 ___ 1/6 ___ 1/6 ___1/6 __ 1/6
Probability : required outcome / Total possible outcomes
X = 0
P(x = 0) = 1/6 + 1/6 = 2/6 = 1/3
X = 1.4
P(x = 1.4) = 1/6 + 1/6 = 2/6 = 1/3
X = 2
P(X) = 1/6
X = 3
P(x) = 1/6
Hence ;
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
A.)
P(X = 1.6) = 0
B.)
P(0.5 < X < 2.7) = p(x = 1.4) + p(x = 2)
P(0.5 < X < 2.7) = 1/3 + 1/6 = (2 + 1) / 6 = 3/6 = 1/2
C.)
P(X > 3) = 0
D.)
P(0 ≤ X < 2) = P(0) + P(1.4)
P(0) + P(1.4) = 1/3 + 1/3 = 2/3
E.)
P(X = 0 or X = 2) = 1/3 + 1/6 = (2 + 1)/6 = 3/6 = 1/2
