Find the probability of not rolling a 2 on a single die.

Answers

Answer:

if the die is fair...

6-2=4

4/6 in fraction form

66% in percentage form

The probability is the ratio of the favorable event to the total number of events. Then the probability of not rolling a 2 is 5/6.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

A fair dice is given.

The total number of the event will be

Total event = 6 {1, 2, 3, 4, 5, 6}

Then the probability of not rolling a 2 on a single die. Then the favorable event will be

Favorable = 1 {1, 3, 4, 5, 6}

Then the probability will be

[tex]P = \dfrac{5}{6}[/tex]

A science experiment calls for mixing 3 and two-thirds cups of distilled water with 1 and three-fourths cups of vinegar and Two-thirds cups of liquid detergent. How much liquid in all, in cups, is needed?

Answers

Answer: 6 and 1/12 cups

Step-by-step explanation:

For this problem, we add 3 and 2/3 + 1 and 3/4 + 2/3. We can change these mixed numbers into improper fractions to make the math easier:

11/3 + 7/4 + 2/3

Next, we can add the 11/3 and 2/3 since they have the same denominator (bottom number). This gives us 13/3.

13/3 + 7/4

Now that we have two fractions, we just add them together. This leaves us with 6 and 1/2.

If you're having trouble with adding fractions with denominators that aren't the same, here are some videos (if you can't click the link, just copy and paste into the search bar):

Step-by-step explanation:

its pretty easy and no explanaion

Answer:

Your answers are C and E

Step-by-step explanation:

C. More than half of the players are 79 inches or taller.

79 in and over = 8 players

under 79 in = 7 players

E. The difference between the tallest and shortest player is 15 in

This tells you to find the range.

Tallest = 84 in

Shortest = 69 in

84 - 69 = 15 in

When the function f(x) = x^2 is multiplied by the value a, when a > 1, how will that affect the graph of the new function, g(x) = ax^2 ?
(1) opens upward and is wider
(3) opens upward and is narrower
(2) opens downward and is wider
(4) opens downward and is narrower

Answers

The function opens upward and is narrower, because we have a vertical dilation.

How is the function transformed?

For a function f(x), a vertical dilation of scale factor k is:

g(x) = k*f(x).

if k > 1, we have a dilation.if 0 < k < 1, we have a contraction.

In this case, the scale factor is a, and we know that a > 1, so we have a dilation.

Then the correct option is 3, the function still opens upwards (because a is positive) and is narrower.
