Hi there!

To calculate a discount or a mark-up in the price of a retail item, you need to multiply the given price of the item by the percentage, like so:

1.35 × 0.2 = 0.27

Then you add or subtract as necessary. In your case you would subtract since you are trying to find a discount price.

1.35 - 0.27 = 1.08

So the final price of the product after the discount is $1.08

Will the following two equations have a solution? Explain. y = 3x + 5 y = 3x - 7

r-ruslan [8.4K]

Answer:

There is no solution because the slopes of the two lines are the same.

Step-by-step explanation:

3x + 5 = 3x - 7

-3x - 3x Subtract 3x from both sides

5 ≠ - 7 No solution

Suppose you are repeating a classic study of starfish and their impact on the ecosystems of tide pools. Using historic data coll

Travka [436]

Answer:

The probability of the number of starfish dropping below 3 is 0.0463.

Step-by-step explanation:

Let X represent the number of starfish in the tide pool.

X follows a Poisson distribution with mean 6.4.

The formula for Poisson distribution is as follows.

$P(X=x) = e^{-6.4} * [6.4^{x} / x!] when x = 0, 1, ...$

$P(X = x) = 0$ otherwise

We need to find the probability that the number of starfish in the tide pool drops below 3.

Therefore, the required probability is:

P(X < 3) = P(X = 0) + P(X = 1) + P(X=2)

$P(X < 3) = e^{-6.4} + (e^{-6.4}*6.4) + (e^{-6.4}*6.4^{2}/2)$

P(X < 3) = 0.00166 + 0.01063 + 0.03403

P (X < 3) = 0.0463

Answer:

1) x=0.465

2) option A.

Step-by-step explanation:

1) The given equation is:

${3}^{x + 2} = 15$ We rewrite this as logarithm to get:

$x + 2 = log_{3}(15)$

The change of base formula is:

$log_{b}(y) = \frac{ log(y) }{ log(b) }$

We apply the change of base formula on the RHS to get:

$x + 2 = \frac{ log(15) }{ log(3) }$

$x + 2 = \frac{1.176}{0.477}$

$x + 2 = 2.465$

Group similar terms:

$x = 2.465 - 2.000 = 0.465$

From the graph, the logarithmic function approaches negative infinity as x approaches -6.

Therefore the vertical asymptote is x=-6

The graph touches the x-axis at x=-5, therefore the x-intercept is x=-5.

The correct answer is A.
