Answer:

x=-21

Step-by-step explanation:

1/3x + 9 = 2

subtract 9 on both sides

1/3x = -7

multiply 3 on both sides bc its the reciprocal of 1/3

and you get -21

Suppose I pick a jelly bean at random from a box containing two red and ten blue ones. I record the color and put the jelly bean

Lubov Fominskaja [6]

Answer:

The probability of getting a red jelly bean both of the times is 0.028.

Step-by-step explanation:

First we have that in the box are 12 jelly beans having 2 red and 10 blue. The probability of getting one of the red jelly beans are the sum of the probability of the 2 red jelly beans, that is:

$ProbabilityRed=\frac{1}{12} +\frac{1}{12}=\frac{2}{12}$

Now we can calculate the probability of getting the red jelly bean twice, this will be the product of the probability of getting each one, is the same probability for the second chance because we are getting the jelly bean back in the box, this is:

$ProbabilityBothRed=\frac{2}{12} *\frac{2}{12}=\frac{4}{144} =\frac{1}{36} =0.028$

Now we have that the probability of getting a red jelly bean both of the times is 0.028.

*HELP PLEASE*

aksik [14]

If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:

$P(AorB)=P(A)+P(B)$
$P(AorB)=\frac{40}{61}+\frac{2}{61}$
$P(AorB)=\frac{42}{61}$
$P(AorB)\approx 68.8\%$

A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that repr

NeX [460]

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.

Any help would be appreciated. (Check the picture)

White raven [17]

the answer would be 0.800375 but when you round it to the nearest tenth it would be 0.8
