UkoKoshka [18]3 years ago
6 0

Answer:

  f(x) = 3^x -3

Step-by-step explanation:

The horizontal asymptote of an unmodified exponential function is y=0. Here, the horizontal asymptote is y=-3, so your answer will be of the form ...

  f(x) = [some growing exponential term] -3

Only the second selection has this form. It also matches the given graph at x=1.

zhenek [66]

Question:

If a sample of 2 hammer is selected

(a) find the probability that all in the sample are defective.

(b) find the probability that none in the sample are defective.

Answer:

a Pr = \frac{2}{110}

b Pr = \frac{72}{110}

Step-by-step explanation:

Given

n = 11 --- hammers

r = 2 --- selection

This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities

Solving (a): Probability that both selection are defective.

For two selections, the probability that all are defective is:

Pr = P(D) * P(D)

Pr = \frac{2}{11} * \frac{2-1}{11-1}

Pr = \frac{2}{11} * \frac{1}{10}

Pr = \frac{2}{110}

Solving (b): Probability that none are defective.

The probability that a selection is not defective is:

P(D') = \frac{9}{11}

For two selections, the probability that all are not defective is:

Pr = P(D') * P(D')

Pr = \frac{9}{11} * \frac{9-1}{11-1}

Pr = \frac{9}{11} * \frac{8}{10}

Pr = \frac{72}{110}

Luke bought 256 ounces of strawberries. he divided them evenly between 8 different pies.
pychu [463]

Answer:

2 pounds.

Step-by-step explanation:

We have been given that Luke bought 256 ounces of strawberries. He divided them evenly between 8 different pies. We are asked to find the pounds of strawberries that Luke put on each pie.

First of all, we will convert 256 ounces into pounds.

We know that 1 pound equals 16 ounces. To convert 256 ounces into pounds, we need to divide 256 by 16.

256 ounces=\frac{256}{16} pounds=16 pounds

Now we will divide 16 pounds by 8 to find number of strawberries put on each pie.

Pounds of strawberries on each pie=\frac{16}{8}

Pounds of strawberries on each pie=2

Therefore, Luke put 2 pounds strawberries on each pie.
