2i-3n=8
i+2n=-3
find i and n
Answers
Answer: n = -2; i = 1
Step-by-step explanation:
i + 2n = -3
i = -3 - 2n
Plug in i in 2i - 3n = 8, we get:
2i - 3n = 8
2(-3 - 2n) - 3n = 8
-6 - 4n - 3n = 8
-6 - 7n = 8
-7n = 14
n = -2
substitute n = -2 into i = -3 - 2n
i = -3 - 2n
i = -3 - 2(-2)
i = -3 + 4
i = 1

Answers
Answer:
1.) 75
2.) 75
3.) 2
Step-by-step explanation:
120n-150=45n
add 150 to both sides
120n=45n+150
subtract 45n from both sides
75n=150
divide by common number, since 75 is half of 150, use 75.

Answers
Remember that i = √(-1), so that
• i ² = -1,
• i ³ = i x i ² = i x (-1) = -i
• i ⁴ = i x i ³ = i x (-i) = -i ² = -(-1) = 1
Multiplying by i again gives i ⁵ = i and the cycle starts over.
The main observation to make here is that raising i to any multiple of 4 returns 1. So,
i ⁴⁸ = (i ⁴)¹² = 1¹² = 1
i ²²³ = i ²²⁰⁺³ = i ²²⁰ x i ³ = (i ⁴)⁵⁵ x i ³ = 1⁵⁵ x (-i) = -i
i ¹¹³ = i ¹¹²⁺¹ = i ¹¹² x i = (i ⁴)²⁸ x i = 1²⁸ x i = i
i ⁸² = i ⁸⁰⁺² = i ⁸⁰ x i ² = (i ⁴)²⁰ x i ² = 1²⁰ x (-1) = -1
i^48 = 1
i^223 = -i
i^113 = i
i^82 = -1

The triangles are similar because they have two sides and the angle between them (EFG) respectively equals, and it’s evident the factor between the two triangles is 2. So EG=2CB=2*8=16
Answer:
the value of EG is 20.
Step-by-step explanation:
3×4 = 12, AB and EF is similar but the value of AB is multiplied by 4 to become 12 for EF.
similarly, 4×4 = 16, BC and FG is similar but the value of BC is multiplied by 4 to become 16 for FG..
In this way, AC and EG are also similar so 5×4 = 20.

An investment of $42 earns 12.5% simple interest for 4 years. How much is to worth?
O $85.50
O $77.76
O $63
O $9.83
Answers
Total amount after 4 years will be $63. If he invest principle amount of $42 for rate of interest of 12.5%.
How to calculate total amount ?Simply multiply the principal amount by the interest rate and the time to calculate simple interest. "Simple Interest = Principal x Interest Rate x Time," the formula says. You must multiply the borrowed principal amount by 1 plus the interest rate.
The simple interest rate is the rate at which you borrow or lend money. When a borrower borrows money from a lender, the lender receives an additional sum of money. The principal is the borrowed money that is given for a specific period of time. The interest is the extra amount paid back to the lender for using the money.
First, converting R percent to r a decimal
r = R/100 = 12.5%/100 = 0.125 per year.
To find the total amount A = P (1+rt).
= 42(1 + 0.125 *6)
= $63
The total amount is $63

The overall pass rate for law school graduates taking the Maryland bar exam has been reported as 76%. Assume that a certain Maryland law school has had 400 of its most recent graduates take the Maryland bar exam, but only 60% passed. When asked about these results, the dean of this university’s law school claims his graduates are just as good as others who have taken the Maryland bar exam, and the low pass rate for the recent graduates was just "one of those statistical fluctuations that happen all the time." If this university’s overall pass rate were really 76%, what would be the probability of a simple random sample of 400 having a pass rate of 60% or less
Answers
Answer:
The probability is [tex]P(X \le 0.60) = 0.000 [/tex]
Step-by-step explanation:
From the question we are told that
The overall pass rate is [tex]R = 76\% = 0.76[/tex]
The sample size is n = 400
The percentage that passed is [tex]k = 60\% = 0.60[/tex]
Generally the standard error is mathematically represented as
[tex]\sigma _{\= x } = \sqrt{\frac{R (1 -R)}{n} }[/tex]
=> [tex]\sigma _{\= x } = \sqrt{\frac{0.76 (1 -0.76)}{400} }[/tex]
=> [tex]\sigma _{\= x } = 0.0214 [/tex]
Generally the probability of a simple random sample of 400 having a pass rate of 60% or less is mathematically represented as
[tex]P(X \le 0.60) = P(\frac{X - R}{ \sigma_{\= x}} \le \frac{0.60 - 0.76}{0.0214} )[/tex]
=> [tex]P(X \le 0.60) = P(Z \le -7.48 )[/tex]
Generally from the z-table
[tex]P(Z \le -7.48 ) = 0.000[/tex]
So
[tex]P(X \le 0.60) = 0.000 [/tex]

Given that n is a positive number, write, in a symbolic statement, ‘the square of a positive number decreased by 10 is 6’

Answer:
n² -10 = 6
Step-by-step explanation:
If n represents a positive number, then "the square of a positive number" is represented by n². When that value is decreased by 10, it becomes ...
n² -10
and if that value is 6, the math expression is ...
n² -10 = 6

Additional comment
Increasing the value by 10 gives ...
n² = 16
and taking the positive square root gives us the value of the number:
n = √16 = 4
in this question we have to multiply 4 with 4 then we have to minus 16 with 10 we get the answer 6
so, first we have to multiply the 4 with 4= 4 × 4 = 16

What is the ratio 0.45 to 1.35 as a simplified fraction?
Answers
Solution:
Given ratio: [tex]0.45:1.35[/tex]
Multiply both sides by 100:
[tex]0.45:1.35[/tex]
[tex]\rightarrow 0.45 \times 100:1.35 \times 100[/tex]
[tex]\rightarrow 45:135[/tex]
Convert the ratio into a fraction:
[tex]\rightarrow 45:135 = \dfrac{45}{135}[/tex]
Simplify the fraction:
[tex]\rightarrow \dfrac{45}{135} = \dfrac{45 \div5}{135 \div 5} =\dfrac{9}{27} = \dfrac{9 \div 9}{27 \div 9} = \dfrac{1}{3}[/tex]
The simplified fraction representing the ratio 0.45 to 1.35 is 1/3.
To express the ratio 0.45 to 1.35 as a simplified fraction, we can divide both numbers by their greatest common divisor (GCD) to simplify the ratio. In this case, the GCD of 45 and 135 is 45.
So, divide both numbers by 45:
0.45 ÷ 45 = 0.01
1.35 ÷ 45 = 0.03
The simplified ratio is 0.01 to 0.03. To make it an integer ratio, we can multiply both parts by 100:
0.01 * 100 = 1
0.03 * 100 = 3
So, the simplified fraction representing the ratio 0.45 to 1.35 is 1/3.

Find the area of the triangle below.
Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth.
Answers
The area of the triangle is the amount of space on it.
The area of the triangle is 85.5 square yard
How to determine the area of the triangle?The given parameters are:
a = 12 yd
b = 16 yd
c = 15 yd
Start by calculating the semi-perimeter (s)
s = 0.5 * (a + b + c)
This gives
s = 0.5 * (12 + 16 + 15)
s = 21.5
The area of the triangle is then calculated as:
[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]
This gives
[tex]A = \sqrt{21.5 * (21.5 - 12) * (21.5 - 16) * (21.5 - 15)[/tex]
Evaluate the product
[tex]A = \sqrt{7301.9375[/tex]
Evaluate the square root
A = 85.5
Hence, the area of the triangle is 85.5 square yard
