en una canasta se tienen 10 bolas cafes, 5 bolas azules y 15 verdes. Si se saca una al azar, ¿cual es la probabilidad de que esta no sea azul? ¿cual es probabilidad de que sea verde?

Answers

Answer 1
Answer:

Answer:

The probability that the selected ball is not blue is (5)/(6).

The probability that the selected ball is green is (1)/(2).

Step-by-step explanation:

The question is:

There are 10 brown balls, 5 blue balls and 15 green balls in a basket. If one is drawn at random, what is the probability that it is not blue? What is the probability that it is green?

Solution:

The probability of an event E is the ratio of the favorable number of outcomes to the total number of outcomes.

P(E)=(n(E))/(N)

The probability of the given event not taking place is known as the complement of that event.

Complement of the event E is,

1 – P (E)

The number of different color balls are as follows:

Brown = n (Br) = 10

Blue = n (Bu) = 5

Green = n (G) = 15

Total = N = 30

Compute the probability of selecting a blue ball as follows:

P(\text{Bu})=\frac{n(\text{Bu})}{N}=(5)/(30)=(1)/(6)

Compute the probability of not selecting a blue ball as follows:

P(\text{Not Bu})=1-P(\text{Bu})

                 =1-(1)/(6)\n\n=(6-1)/(6)\n\n=(5)/(6)

Thus, the probability that the selected ball is not blue is (5)/(6).

Compute the probability of selecting a green ball as follows:

P(\text{G})=\frac{n(\text{G})}{N}=(15)/(30)=(1)/(2)

Thus, the probability that the selected ball is green is (1)/(2).

The 4th option is correct.

The equation of the line is: (y + 3) = 3 (x - 4)

Step-by-step explanation:

The equation of a line using two points, (x₁, y₁) and (x₂, y₂) is:

(y-y_(1))=m(x-x_(1))

Here m is the slope of the line.

The formula to compute slope is:

m=(y_(2)-y_(1))/(x_(2)-x_(1))

Given: The two points are (4, -3) and (5, 0)

The equation of the line passing through the points (4, -3) and (5, 0) is:

(y-y_(1))=m(x-x_(1))\n(y-y_(1))=(y_(2)-y_(1))/(x_(2)-x_(1))(x-x_(1))\n(y-(-3))=(0-(-3))/(5-4)(x-4)\n(y+3)=3(x-4)

Thus, the line passing through the points (4, -3) and (5, 0) is (y + 3) = 3 (x - 4).

The one above is correct

We also have

4x+4y=60

2* 2x+4y=60\n\n2*3y+4y=60\n\n10y=60\n\ny=6\n\n2x=3*6\n\nx=9\$

Two less than three-fourths of a number is, at most, negative seventeen. what is the range of values for the number?

Answers

Answer:

x\leq -20

values ranging fromminus infinity to negative 20

Step-by-step explanation:

we write the inequality associated with the text in terms of the unknown number "x" as:

(3)/(4) x-2\leq -17

then, we solve for "x" by adding 2 to both sides, and then isolating "x" on the left as shown below:

(3)/(4) x-2\leq -17\n(3)/(4) x\leq -17+2\n(3)/(4) x\leq -15\n3\,x\leq -60\nx\leq -(60)/(3) \nx\leq -20

then, the range of x-values is from minus infinity to negative 20

SHOW WORK! PLEASE HELP ASAP IF YOU CAN :(A stack of index cards is 3/4 of an inch tall. If each card is 3/160 of an inch thick, how many index cards are in the stack?

Answers

Answer:

so what you have to do first is simplify into variables

S=A 3/4 stack of index cards

C= 3/160

first you can do this with a calculator, divide 3/4 of an inch by 3/160 of an inch.

3/4÷3/160=40

Here is my work shown :)

Male the division into multiplication and swap the numbers in 3/160 to 160/3

3/4 x 160/3

For fraction multiplication, multiply the numerators and then multiply the demoninators to get

3 x 160/4 x 3= 480/12

Divide 480 by 12 which is forty

there you go :) sorry if the answers are messed up and there are spelling errors. but in conclusion the answer is 40
