Answer:

$\boxed{\dfrac{y}{x}}$

Step-by-step explanation:

$\dfrac{\dfrac{1}{x} }{\dfrac{1}{y} } \ \text{can also be written as} \ \dfrac{1}{x} \div \dfrac{1}{y}$

-------------------------------------------

$\rightarrow \dfrac{1}{x} \div \dfrac{1}{y}$

Simplifying the expression using "a ÷ b = a x 1/b"

$\rightarrow \dfrac{1}{x} \times y$

$\rightarrow \boxed{\dfrac{y}{x}}$

7. What is the solution to x2 + 10x + 27 = 0 when written in the form a ± bi? (1 point)

Answer:

The correct answer is D. -5 +/- i√2

Step-by-step explanation:

Let's solve for x, the equation given to us, this way, using the quadratic formula:

x = (- b +/- √b² - 4ac)/2a

Replacing with the real values, we have:

x = (-10 +/- √10² - 4 * 1 * 27)/2

x = (-10 +/- √100 -108)/2

x = (-10 +/- √-8)/2

x = (-10 +/- √-1 * 4 * 2)/2 Let's recall that √-1 = i

x = (-10 +/- 2i√2)/2

x = 2 (-5 +/- i√2)/2 (Dividing by 2 both the numerator and the denominator)

x₁ = -5 + i√2

x₂ = -5 - i√2

The correct answer is D. -5 +/- i√2

Step-by-step explanation:

Let's look at what we know. We know that...

P=2000

r=0.04 (Change 4% to a decimal)

t=7 (25 years minus 18 years equals 7)

n=1

Since we are compounding each year, we need to use this equation: $P(1+\frac{r}{n} )^{nt}$

Now just plug the numbers in: (Answer to #1:) $2000(1+\frac{0.04}{1} )^{(1*7)}$

This equals 2631.86

When we round, this equals to $2,632. (Answer to #2).

Answer:

P (A) = 0.45

Step-by-step explanation:

The addition rule of probability states that:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

Given:

$P(A\cup B) = 0.7\\P(A\cap B) = 0.1\\P(B) = 0.35$

Compute the value of P (A) as follows:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\P(A)=P(A\cup B) + P(A\cap B) - P(B)\\= 0.7 +0.1-0.35\\=0.45$

Thus, the probability of A is, P (A) = 0.45.
