Answer:

x,y ⇒x+10, y+10

Step-by-step explanation:

from looking at the graphs we can see there is only horizontal and vertical translations

take any point, for example the point C and it's transformed counterpart C'

and determine the change in x and y position

the point is translated 10 right and 10 up

so from x,y ⇒x+10, y+10

a jar contains ten black buttons and six brown buttons. If nine buttons are picked at random, what is the probability that exact

Anuta_ua [19.1K]

Answer:

33.04% probability that exactly five of them are black

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the buttons are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

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

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

Desired outcomes:

Five black buttons, from a set of 10

Four brown buttons, from a set of 6.

$D = C_{10,5}*C_{6,4} = \frac{10!}{5!(10-5)!}*\frac{6!}{4!(6-4)!} = 3780$

Total outcomes:

Nine buttons, from a set of 16.

$T = C_{16,9} = \frac{16!}{9!(16-9)!} = 11440$

Probability:

$p = \frac{D}{T} = \frac{3780}{11440} = 0.3304$

33.04% probability that exactly five of them are black

nlexa [21]

Answer:

(A) Type I error in the context of this problem is chances of regulators believing that the mean temperature of the discharged water is more than 150°F but in actual the mean temperature of the discharged water was 150°F.

(B) Type II error in the context of this problem is chances of regulators believing that the mean temperature of the discharged water is no more than 150°F but in actual the mean temperature of the discharged water was more than 150°F.

(C) An environmental group will consider the Type II error more serious.

Step-by-step explanation:

We are given that a power plant discharges water into a river. Regulators determine that as long as the mean temperature of the discharged water is no more than 150°F, there will be no negative effects on the river’s ecosystem.

We are also given with the following hypothesis;

Null Hypothesis, $H_0$ : $\mu$ = 150°F

Alternate Hypothesis, $H_a$ : $\mu$ > 150°F

(A) Type I error states that Probability of rejecting null hypothesis given the fact that null hypothesis was true or in other words Probability of rejecting a true hypothesis.

So, Type I error in the context of this problem is chances of regulators believing that the mean temperature of the discharged water is more than 150°F but in actual the mean temperature of the discharged water was 150°F.

(B) Type II error states that Probability of accepting null hypothesis given the fact that null hypothesis was false or in other words Probability of accepting a false hypothesis.

So, Type II error in the context of this problem is chances of regulators believing that the mean temperature of the discharged water is no more than 150°F but in actual the mean temperature of the discharged water was more than 150°F.

(C) An environmental group will consider the Type II error more serious because by committing Type II error they believe that the mean temperature of the discharged water is no more than 150°F and they assume that there is no negative effects on the river’s ecosystem but in reality that the mean temperature of the discharged water was more than 150°F and it is producing negative effects on the river’s ecosystem.

a ski chalet offers 2 weekend packages. one package provides 2 nights and 3 meals for$280. the other provides 2 nights and 5 mea

Helga [31]

1st formula 2n + 3m = 280

2nd formula 2n + 5m = 320

rearrange 1st formula to equal n:

2n = -3m + 280
 n = -3/2 m + 140

rearrange 2nd formula to equal n:

2n = -5m + 320
 n = -5/2m + 160
 so now you have

-3/2m + 140 = -5/2m + 160

Rearrange to become:
 -3/2m + 5/2m = 160 - 140
 m = 20

Now place 20 into the very 1st equation in place of the letter m
 2n + 3(20) = 280
 2n + 60 = 280
 2n = 220
 n = 110

so it costs $110 per night, $20 per meal
