Solve for n in each of the following equations:
(a)
n^ Pbase2=110
Answer:
[tex]n = 11[/tex]
Step-by-step explanation:
Given
[tex]^nP_2 = 110[/tex]
Required
Solve for n
[tex]^nP_2 = 110[/tex]
Start by applying permutation formula:
[tex]\frac{n!}{(n-2)!} = 110[/tex]
Expand the numerator
[tex]\frac{n*(n-1) * (n-2)!}{(n-2)!} = 110[/tex]
(n-2)! cancels out
[tex]n*(n-1) = 110[/tex]
Expand
[tex]n^2 - n = 110[/tex]
Subtract 110 from both sides
[tex]n^2 - n -110= 110-110[/tex]
[tex]n^2 - n -110= 0[/tex]
Expand:
[tex]n^2 - 11n +10n-110= 0[/tex]
Factorize:
[tex]n(n-11) +10(n-11)= 0[/tex]
[tex](n+10)(n-11) = 0[/tex]
This implies that:
[tex]n + 10 = 0\ or\ n - 11 = 0[/tex]
[tex]n = -10\ or\ n = 11[/tex]
But n can't be negative.
So:
[tex]n = 11[/tex]

What does the inverse of a positive number mean?
Answer:
When it comes to positive and negative numbers, you can think of the inverse as being the "opposite." For example, for 5, the inverse is -5.

The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 2:5
Surface area: 80
volume: 352
Surface area: ?
volume: ?
Answer:
Surface area: 500
Volume: 5500
Step-by-step explanation:
Scale factor: 2:5
This means that the dimensions of the larger figure are 5/2 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/2) by the original surface area(80). So
[tex]S = (\frac{5}{2})^2 \times 80 = \frac{25}{4} \times 80 = 25 \times 20 = 500[/tex]
Volume:
The volume is found multiplying the cube of the change(5/2) by the original volume(352). So
[tex]S = (\frac{5}{2})^3 \times 352= \frac{125}{8} \times 352 = 125 \times 44 = 5500[/tex]
which one is correct????
Given:
[tex]m\angle ABC=46^\circ[/tex]
BD bisects angle ABC.
To find:
The [tex]m\angle ABD[/tex].
Solution:
It is given that, BD bisects angle ABC. It means, BD divides the angle ABC is two equal parts. So,
[tex]m\angle ABD=m\angle DBC=\dfrac{\angle ABC}{2}[/tex]
We need to find [tex]m\angle ABD[/tex], so
[tex]m\angle ABD=\dfrac{\angle ABC}{2}[/tex]
[tex]m\angle ABD=\dfrac{46^\circ}{2}[/tex]
[tex]m\angle ABD=23^\circ[/tex]
Therefore, the [tex]m\angle ABD[/tex] is 23°. Hence first option is correct.
find the value of p in parallelogram
Answer:
p = 11
Step-by-step explanation:
In a parallelogram BA and CD are parallel so you would set the problem up 7p = p +66
- p both sides
6p = 66
divide 6 both sides
p = 11
Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e2t 1 bacteria per hour. Find the population size after four hours
Complete Question
Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e^2t 1 bacteria per hour. Find the population size after four hours
Answer:
3010
Step-by-step explanation:
We were given the rate: 2e^2t
Step 1
We would integrate
P = Population
dP/dt = 2e^2t
dP =( 2e^2t) dt
∫dP = ∫ 2e^2t dt
P(t) = (2e^2t)/2 + C
P(t) = e^2t + C
Step 2
We solve for C
The culture initially has 30 bacteria
When t = 0
P(0) = 30
P(0) = e^2t + C
30 = e^2× 0 + C
30 = 1 + C
C = 30 - 1
C = 29
Step 3
Find the population size after four hours
t = 4, C = 29
P(t) = e^2t + C
P(4) = e^2 × 4 + 29
P(4) = e^8 + 29
P(4) = 3009.957987
Approximately = 3010 bacteria

James earned 96$ by mowing his neighbor yard. He spent 50% of his money on a video game. He is going to save 75% of his remaining money. How much would he save
Answer:
36
Step-by-step explanation
Subtract 50% from $96.00
96.00 - 48.00 = 48.00
Find out what is 75% of 48
48.00 - 75% = 36

Step-by-step explanation:
Suppose you want to investigate the proportion of women police officers. How large should a sample be if the margin of error is .05 for a 92% confidence interval
Answer:
A sample of 307 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this question, we have that:
We dont know the true proportion of women police officers, so we use [tex]\pi = 0.5[/tex], which is when the largest sample size would be needed.
92% confidence level
So [tex]\alpha = 0.08[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.08}{2} = 0.96[/tex], so [tex]Z = 1.75[/tex].
How large should a sample be if the margin of error is .05 for a 92% confidence interval
We need a sample of n, and n is found when [tex]M = 0.05[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 1.75\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.05\sqrt{n} = 1.75*0.5[/tex]
[tex]\sqrt{n} = 17.5[/tex]
[tex](\sqrt{n})^2 = (17.5)^2[/tex]
[tex]n = 306.25[/tex]
Rounding up
A sample of 307 is needed.

Solve the inequality
5x+2 < 32
Answer:
x=6
Take 2 to the other side, the sign becomes negative. You're then left with 5x is less than 30. After that just divide both sides with 5 so that you're left with x.
The value of x is less than 6
What is inequality?Inequality shows the relationship between two values in an algebraic equation that are not equal.
The given inequality is 5x + 2 < 32
Subtract -2 from both sides of the inequality then we get
5x < 30
Next, divide both sides by 5, then we get the range of x.
i.e x < 6
The solution to the given inequality is x < 6 .
