X+y = 24x-y = 15 Thus, x=15+y Substitute for x in first equation becomes 15 +y + y = 24. 2y=9; therefore y=4.5, and since x = 24-y, x= 19.5 Check answer: 4.5 + 19.5 = 24; 19.5-4.5 = 15

Suppose you have rolled a six-sided die fifty times and recorded the result of each roll.
a_sh-v [17]

Using it's concept, it is found that the relative frequency  probability of rolling an even number based on this experiment is \frac{11}{25}.

A relative frequency is the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

  • 50 dices are thrown, hence T = 50.
  • 22 resulted in an even number, hence D = 22

The <u>relative frequency</u> is given by:

f = \frac{D}{T} = \frac{22}{50} = \frac{11}{25}

Equation: -5 3/4- 3 1/2 Please help meh. ​
vampirchik [111]

Answer:

-9\frac{1}{4}

Step-by-step explanation:

-5\frac{3}{4}-3\frac{1}{2}

Step 1: Factor out the common term -1

=-\left(5\frac{3}{4}+3\frac{1}{2}\right)

Step 2: Add the whole numbers

5 + 3 = 8

Step 3: Combine the fractions:

\frac{3}{4}+\frac{1}{2} = \frac{5}{4}\\\\=-\left(8+\frac{5}{4}\right)

Step 4: Convert the improper fractions to mixed numbers

\frac{5}{4} = 1\frac{1}{4}\\\\=-\left(8+1\frac{1}{4}\right)

Step 5: Add the numbers

8 + 1 =9 \\\\=-9\frac{1}{4}

Therefore, the answer to the equation is -9\frac{1}{4} in fraction, and decimal; 9.25
