Step-by-step explanation:

When a number is grouped with the x in this problem it will move the graph right (if it is is minus) and it will

move it left ( if it is plus), therefore the original graph will be move to the left 5 units.

A stationary store has decided to accept a large shipment of ball-point pens if an inspection of 17 randomly selected pens yield

Leno4ka [110]

Answer:

0.762 = 76.2% probability that this shipment is accepted

Step-by-step explanation:

For each pen, there are only two possible outcomes. Either it is defective, or it is not. The probability of a pen being defective is independent from other pens. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

17 randomly selected pens

This means that $n = 17$

(a) Find the probability that this shipment is accepted if 10% of the total shipment is defective. (Use 3 decimal places.)

This is $P(X \leq 2)$ when $p = 0.1$ . So

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{17,0}.(0.1)^{0}.(0.9)^{17} = 0.167$

$P(X = 1) = C_{17,1}.(0.1)^{1}.(0.9)^{16} = 0.315$

$P(X = 2) = C_{17,2}.(0.1)^{2}.(0.9)^{15} = 0.280$

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.167 + 0.315 + 0.280 = 0.762$

0.762 = 76.2% probability that this shipment is accepted

Answer:

1/2652

Step-by-step explanation:

52 cards one jack spades 1/52

now 51 cards left one jack diamonds 1/51

1/52 * 1/51 = 1 / 2652

Allison has 5 times as many baseball cards as football cards. In all, she has 120 baseball and football cards. How many baseball

Ede4ka [16]

If Jim has x football cards He will have 5x baseballs cards Thus x + 5x = 120 > total # of cards 6x = 120 x= 120/6 = 20 so Jim has 5x baseball cards = 20*5 =100 baseball cards

Please please help me- thank you

tester [92]

Answer:

y=2x+7

Step-by-step explanation:

The slope of the new line is 2 because that is the opposite of -1/2

To find the equation of the line, plug the points (-2,3) into point-slope form:

y-y1=m(x-x1).

y-3=2(x+2)

Multiply (x+2) by 2 and simplify to get the final answer.

y-3=2x+4

y=2x+7
