A single die is rolled. Find the probability of each of the following events :

IceJOKER [234]

$\frac{1}{2}$ and $\frac{1}{3}$

There are 6 possible outcomes when rolling a die, 1, 2, 3, 4 , 5, 6

numbers less than 4 are 1, 2, 3

P( number less than 4 ) = $\frac{3}{6}$ = $\frac{1}{2}$

numbers greater than 4 are 5, 6

P( number greater than 4 ) = $\frac{2}{6}$ = $\frac{1}{3}$

Which measure would be used to describe how far a test score is from the average test score?

weeeeeb [17]

Answer:

Standard deviation

Step-by-step explanation:

You use the standard deviation to determine how far the particular mark is further away from the mean. It shows how that particular data point agrees with the mean.

A is wrong

The mean is the average of the data. It does not tell you the information needed in this question.

B is wrong

The mode is just the highest in frequency. It does not say anything about agreeing with the mean

C is wrong

This is wrong and it refers to the middle number in the data set

An Ice cream parlor sells 5 ice cream sundaes for every 2 popsicles that they sell. If they sell 35 ice cream sundaes, how many

docker41 [41]

Answer:

14 popsicles

Step-by-step explanation:

The problem situation is related to the topic of "Proportion" in Mathematics. This shows two ratios being equal in a statement.

Proportion Formula: a:b = c:d (you can also rewrite this as $\frac{a}{b}$ = $\frac{c}{d}$ )

1. Write the Proportion

5 ice cream sundaes : 2 popsicles = 35 ice cream sundaes : x
<em>let x be the number of popsicles</em>
this can also be written as: $\frac{5}{2}$ = $\frac{35}{x}$

2. Multiply in order to find the cross products.

5 ice cream sundaes × x = 35 ice cream sundaes × 2 popsicles

3. Divide in order to find x.

$\frac{5xX}{5}$ = $\frac{35x2}{5}$

x = 14 popsicles
