Answer:
10,000 universes with the smaller number of atoms would fit inside the larger universe
Step-by-step explanation:
The correct question is as follows;
Physicists estimate that there are between 10^78 and 10^82 atoms in the universe. How do these two numbers compare with one another? If the larger number is right, how many universes with the smaller number of atoms would fit inside the larger universe?
Solution
To find the amount of the smaller number of atoms that will fit into the larger, we simply divide
Thus, we have;
10^82/10^78 = 10^4 = 10,000
Estimates are used to give the approximated value of a quantity.
10000 of the smaller universe will fit in the larger universe.
The number of atoms is:
[tex]\mathbf{n_1 = 10^{78}}[/tex]
[tex]\mathbf{n_2 = 10^{82}}[/tex]
(a) The larger universe
By comparison,
[tex]\mathbf{10^{82} > 10^{78}}[/tex]
This means that: the atoms in the second universe are larger than the number of atoms in the first.
(b) The number of small universe in the large universe
This is calculated by dividing the number of atoms in the large universe by the small universe
So, we have:
[tex]\mathbf{n = \frac{n_2}{n_1}}[/tex]
[tex]\mathbf{n = \frac{10^{82} }{ 10^{78}}}[/tex]
Apply law of logarithm
[tex]\mathbf{n = 10^{82 - 78} }[/tex]
[tex]\mathbf{n = 10^{4} }[/tex]
[tex]\mathbf{n = 10000 }[/tex]
Hence, 10000 of the smaller universe will fit in the larger universe.

Step-by-step explanation:
The number A8 is a two-digit number with a digit A and units (ones) digit 8.
Similarly, 3B is a two-digit number with tens digit 3 and units digit B.
When A8 is multiplied by 3B, the result is the four digit number 0730. That is,
A8
x 3B
C730
If A, B, and C are each different digits from 0 to 9, determine the values of A.
B. and C.
Answer:
A = 7
B = 5
C = 2
Step-by-step explanation:
We are given;
A8 × 3B = C730
Now, by inspection, in multiplication of the above, the product of 8 and B must produce a number whose unit digit is 0.
Thus,the only two single digit numbers that can fit this description for B is either 5 or 0 since if they would yield a unit digit of 0 when multiplied by8.
Now, let's test 0.
If B is 0, it means the unit digit of C730 is 0 as wanted while the remaining product of A8 and 3 should yield C73. Now product of A8 and 3 would produce a number with a last digit of 4. But our last digit there in C73 is 3. Thus, it means B cannot be 0 but is 5.
Thus, it means 3B is 35.
Now, we are told that A, B and C could be any single digit number.
from 0 - 9.
Thus, the maximum value of A is 9.
Let's try to put 9 for A and multiply by 35.
If A is 9,then 98 × 35 = 3430
It means that the maximum value of C is 3.
Thus, C can either be 3 or less than 3. So, C is either 1, 2, or 3
Now, if C = 1, it means the C730 is now 1730.
Thus,A8 will be: 1730/35 = 49.43
This is a decimal and thus, it means C ≠ 1.
Now,if C = 2, it means the C730 is now 2730.
Thus,A8 will be: 2730/35 = 78
This is a whole number and thus, it means C = 2
Now,if C = 3, it means the C730 is now 3730.
Thus,A8 will be: 3730/35 = 106.57
This is a decimal and thus, it means C ≠ 3
Thus; A8 is 78 when C = 2
So, A = 7

It ▼(Choose one) appropriate to use the normal curve, since =np ▼(Choose one)10 and =n−1p ▼(Choose one) 10.
Answer:
Yes it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure
Step-by-step explanation:
From the question we are told that
The population proportion is p=0.4
The sample size is n = 39
The sample proportion is [tex]\^ p = 0.43[/tex]
Generally for normal approximation to be used
[tex]np > 10[/tex]
so np = 39 * 0.4 = 15.6 > 10
and [tex]n(1- p) > 10[/tex]
so n(1-p ) = 39(1-0.4) = 23.4 >10
Given that the both condition is meet it mean that it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

Answer:
trust me on this answer. It is D, a = 1, b = 2, c = 3
Step-by-step explanation:
Okay, so the problem is 5/8 divided by 3/8.
So, you find the reciprocal, which then is 5/8 x 8/3
Since there is an 8 is both the first denominator and the second numerator, you cross them out, which leaves you 5/3
So, 5 can go into 3, only 1 time.
5/3 = 3/3 + 2/3
So, 3/3 + 2/3 = 1 2/3
Therefore, D is the answer of choice.

Step-by-step explanation:
The following pieces of empirical evidence have been collected over the years: Historical trend data show an increase in temperature globally Levels of carbon dioxide gas are on the rise Levels of methane gas are on the rise Glacial ice is melting Antarctic and Artic sea ice is melting Which statement best explains the significance of this empirical evidence?
a
It provides a hypothesis for the climate of the past.
b
It provides data for science journals and textbooks.
c
It supports the scientific explanation for global warming.
d
It predicts future weather patterns.
Answer:
C. It supports the scientific explanation for global warming.
Explanation:
The listed pieces of empirical evidence support the scientific explanation for global warming. Global warming is the long-term heating of Earth's climate, and the increase in levels of carbon dioxide and methane is the reason why glacial ice in the Antarctic and Arctic sea is melting.
These pieces of evidence don't deal with the past of the future. They tell us what is going on right now. Based on them, we could make an assumption about what is going to happen in the future, but there are no predictions here.
Also, this data can be used for science journals and textbooks, but that purpose is not expressed here.
This leaves us with option C as the correct one.
Question Help When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 36 batteries and determine whether each is within specifications. The entire shipment is accepted if at most 2 batteries do not meet specifications. A shipment contains 3000 batteries, and 3% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected?
Answer:
The probability is [tex]P(X \le 2 ) = 0.9072[/tex]
The company will accept 90.72% of the shipment and will reject [tex](100 -90.72) = 9.2\%[/tex] of the shipment , so many of the shipment are rejected
Step-by-step explanation:
From the question we are told that
The sample size is n = 36
The proportion that did not meet the requirement is [tex]p = 0.03[/tex]
Generally the probability that the whole shipment is accepted is equivalent to the probability that there is at most 2 batteries that do not meet the requirement , this is mathematically represented as
[tex]P(X \le 2 ) = [ P(X = 0 ) + P(X = 1 ) + P(X = 0)][/tex]
=> [tex]P(X \le 2 ) = [ [^{n}C_0 * (p)^{0} *(1-p)^{n-0} ] + [^{n}C_1 * (p)^{1} *(1-p)^{n-1} ] + [^{n}C_2 * (p)^{2} *(1-p)^{n-2} ]][/tex]
Here C stands for Combination (so we will be making the combination function in our calculators )
So
=> [tex]P(X \le 2 ) = [ [^{36}C_0 * (0.03)^{0} *(1-0.03)^{36-0} ] + [^{36}C_1 * (0.03)^{1} *(1-0.03)^{36-1} ] + [^{36}C_2 * (0.03)^{2} *(1-0.03)^{36-2} ]][/tex]
=> [tex]P(X \le 2 ) = [ [1 * 1 * 0.3340 ] + [36* 0.03 *0.3444 ] + [630 * 0.0009 *(0.355 ]][/tex]
=>[tex]P(X \le 2 ) = 0.9072[/tex]
The company will accept 90.72% of the shipment and will reject [tex](100 -90.72) = 9.2\%[/tex] of the shipment , so many of the shipment are rejected

Which steps can be used to verify that tan(w + Pi) = tan(w)? Rewrite tan(w + Pi) as tan(w) + tan(Pi). Then simplify the expression using tan(Pi) = 1. Rewrite tan(w + Pi) as tan(w) + tan(Pi). Then simplify the expression using tan(Pi) = 0. Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 1. Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.
Answer:
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
Step-by-step explanation:
According to tangent sub identity
Tan(A+B) = TanA+TanB/1-tanAtanB
Applying this in question
Tan(w+Pi) = tan(w)+tan(pi)/1-tan(w)tan(pi)
According to trig identity, tan(pi) = 0
Substitute
Tan(w+Pi) = tan(w)+0/1-tan(w)(0)
Tan(w+Pi) = tan(w)/1
Tan(w+Pi) = tan(w) (proved!)
Hence the correct option is
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
The given expression can be prove by using tangent sub-identity. In the solution we will use [tex]\tan (A+B)[/tex] sub-identity.
The correct option is Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.
Given:
The given expression is as follows,
[tex]\tan(w+\pi)=\tan(w)[/tex]
Write the tangent sub-identity.
[tex]\tan(A+B)=\dfrac{\tan A+\tan B}{1-\tan A\tan B}[/tex]
Now replace [tex]A[/tex] with [tex]w[/tex] and [tex]B[/tex] with [tex]\pi[/tex].
[tex]\tan(w+\pi)=\dfrac{\tan w+\tan \pi}{1-\tan w\tan \pi}[/tex]
Substitute 0 for [tex]\tan \pi[/tex].
[tex]\tan(w+\pi)=\dfrac{\tan w+0}{1-\tan w\times 0}\\\tan(w+\pi)=\tan w[/tex]
Thus, the correct option is Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.
