Answer:(1/2,2)

Step-by-step explanation:

y = 2x + 1

y = 6x - 1

---------

2x+1=6x-1

1+1=6x-2x

2=4x

x=4/2

x=1/2

y=2*1/2+1

y=2

which of the following is an experiment,? A. Rolling a pair die. B.Rolling two pair dice twice. C.Tossing a coin. D.None of thes
sergejj [24]

Step-by-step explanation:

Hint : we will check for each option whether it is an experiment or not by using the concepts of probability first we will check then if a coin is tossed then it is an experiment or not ? then we will check that if a dice is rolled is it an experiment or not and then we will repeat the same process for choosing a marble from a jar

complete step by step answer and event is a set of outcomes of an experiment to which probability is assigned as take an example when we and I the possibility of 5 appearing on the die is an event if for tossing a coin we do not know the result when a coin is tossed in can give any result whether it will be a head or tails so this is an example for a random experiment if a six-sided dice will be rolled then we do not know what is about to come there result can be anything from 126 so it is also an example for random experiment choosing a marble from a jar is also an experiment because we are choosing one marble from the jar and experiment is a work in which a result can be anything hence option d is the correct option not probability is how likely something is about to happen when a coin is tossed there are two possibility outcomes heads or tails show the probability of an outcome 1

( number of ways it can happen )÷

( total number of outcomes)

so when a coin is tossed the total number of outcomes are to solve the probability of a current head is 1/2

There are six balls in the bag. Two are basketballs, three are playground balls, and one is a soccer ball. What is the probabili
aleksandr82 [10.1K]

Answer:

\frac{1}{6}=0.16

Step-by-step explanation:

Given : There are six balls in bag

             Basketballs=2

             Playground balls =3

             Soccer ball =1

To Find : the probability that if you pick one of the balls without looking, it will be a soccer ball

Solution :

Total no. of balls = 6

No. of soccer balls = 1

Probability = favorable outcomes / total outcomes

Since total outcomes = total no. of balls =6

And favorable outcome = no. of soccer balls = 1

Thus , Probability of getting soccer ball = \frac{1}{6}

Hence the probability that if you pick one of the balls without looking, it will be a soccer ball:

\frac{1}{6}=0.16

BRAINLEISET!!!!!!!!! pls
zvonat [6]

Answer:

18 cups of dried split peas. 16 quarts of water. 6 cups of chopped onions. 8 cups chopped celery. 16 pounds ham shank.

Step-by-step explanation:

Since that is a recipe for 8 people and 8 is a factor of 32, we can multiply the ingredient amounts by 4 (4 x 8 is 32).

2 1/4 c x 8 = 18 c.

2 qt x 8 = 16 qt.

3/4 c x 8 = 6 c.

1 c x 8 = 8 c.

2 lb x 8 = 16 lb.
