What is P(3 or even) when rolling a die?
Alisiya [41]
The total number of sides on a dice are 6.
The number of even numbers on a dice are 3 (2,4,6).
Since we have 3 even numbers and include the number 3, we have a total of 4/6. 4/6 simplifies to 2/3.
Your probability of rolling a 3 or even is 2/3.

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$100000\\ P=\textit{original amount deposited}\\ r=rate\to 6.6\%\to \frac{6.6}{100}\dotfill &0.066\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus two} \end{array}\dotfill &2\\ t=years\dotfill &20 \end{cases}

100000=P\left(1+\frac{0.066}{2}\right)^{2\cdot 20}\implies 100000=P(1.033)^{40} \\\\\\ \cfrac{100000}{1.033^{40}}=P\implies 27288.97\approx P

The cost of eight stress balls and five T-shirts is $111.75. The cost of twelve stress balls and four T-shirts is $102.00. What
aksik [14]
Let's say stress ball cost x and t shirt cost y
8x+5y=111.75
12x+4y=102.00→3x+y=25.5→y=25.5-3x

8x+5(25.5-3x)= 111.75
8x+127.5-15x=111.75
-7x=-15.75
x=2.25

12x+4y=102
12(2.25)+4y=102
27+4y=102
4y=75
y=18.75

d is the correct answer
