Leila and jo are two of the partners in a business. Leila makes $3 in profits for every $4 that jo makes. If jo makes $60 profit

Aleonysh [2.5K]

Let

x-------> Leila 's profit

y------> Jo's profit

we know that

$\frac{x}{y} =\frac{3}{4}$ ----------> equation $1$

For $y=\$60$

Find the value of x

Substitute the value of y in the equation $1$

$\frac{x}{60} =\frac{3}{4}$

$x=60*\frac{3}{4}$

$x=\$45$

therefore

the answer is

Leila make $\$45$ in profit

Use the Central Limit Theorem to find a mean given a probability Question A video game company sells an average of 132 games a m

aev [14]

Answer:

The number of games must a store sell in order to be eligible for a reward is 135.

Step-by-step explanation:

Let the random variable X represent the number of video games sold in a month by the sores.

The random variable X has a mean of, μ = 132 and a standard deviation of, σ = 9.

It is provided that the company is looking to reward stores that are selling in the top 7%.

That is, $P (\bar X > \bar x) = 0.07$ .

The z-score related to this probability is, z = 1.48.

Compute the number of games must a store sell in order to be eligible for a reward as follows:

$z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}$

$\bar x=\mu+z\cdot \sigma/\sqrt{n}$

$=132+1.48\times (9/\sqrt{36})\\\\=132+2.22\\\\=134.22\\\\\approx 135$

Thus, the number of games must a store sell in order to be eligible for a reward is 135.

Does anyone know the answer to this? Algebra 2

natulia [17]

Answer:

Step-by-step explanation:

Sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

If, sinθ = - $\frac{1}{2}$ and π < θ < $\frac{3\pi }{2}$

Since, sinθ is negative, angle θ will be in IIIrd quadrant.

And the measure of angle θ will be (180° + 30°)

θ = 210°

It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.

Therefore, cos(210°) = $-\frac{\sqrt{3} }{2}$

tan(210°) = $\frac{1}{\sqrt{3} }$

csc(210°) = $-\frac{1}{2}$

sec(210°) = $-\frac{2}{\sqrt{3} }$

cot(210°) = √3
