1 answer:
pav-90 [236]2 years ago
4 0

Answer:

B

Step-by-step explanation:

The first week, she worked

3  \times 2\frac{1}{2}  = 3 \times  \frac{5}{2}  = \frac{15}{2}

The second week, she worked

3 \times 2 \frac{1}{4}  = 3 \times  \frac{9}{4}  =  \frac{27}{4}

Total number of hours she worked over these 6 days

\frac{15}{2}  +  \frac{27}{4}  =  \frac{57}{4}  =  14\frac{1}{4}

You roll five number cubes and the numbers rolled are 1,2, 3, 4, and 5. Are the events independent? Explain.
trasher [3.6K]
Answer: B

Explanation

When rolling a dice, no matter how many times you get an outcome, it can never determine the exact outcome of the next roll, hence it is termed an independent event.

Hope this helps :)

Split them into triangles and rectangles. 

15 x 9 = 135
(6 x 3) / 2 = 9
135 - 9 = 126

This gives you the area of the rectangle with the triangle taken out of it.

15 - 6 = 9
(9 x 6) / 2 = 27

This gives you the area of the triangle at the top.

Add these together: 27 + 126 = 153, and that's your answer!

Hope I helped x

Iridium -192 has a half life of 74 days after 148 days, how many milligrams of 900 mg sample will remain?
Ad libitum [116K]
\bf \textit{Amount for Exponential Decay using Half-Life}
\\\\
A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &900\\
t=\textit{elapsed time}\to &148\\
h=\textit{half-life}\to &74
\end{cases}
\\\\\\
A=900\left( \frac{1}{2} \right)^{\frac{148}{74}}\implies A=900\left( \frac{1}{2} \right)^2\implies A=225
