Answer:
The expected value of this game to me is 5 odd x $5 = $25.
There is 1/2 chances of winning and losing.
The expectations after playing 100 times is 100x5 oddx$5=$2500
Step-by-step explanation:
Odd is the probability or likelihood of an event occurring.
Answer:
30 inches
Step-by-step explanation:
She takes 12 equal sized steps and they all add up to 10 yards.
The length of each step (in yards) is:
10 / 12 = 5/6 yards
The question requires the answer in inches, therefore, we must convert this to inches:
1 yard = 36 inches
5/6 yards = 5/6 * 36 = 30 inches
Each step is 30 inches long.
Answer:
5 birds flew away
Step-by-step explanation:
1/6x6=1
( 1 bird flew away)
so, 6-1=5
First, the best advice I can give you is to go to sleep. You pretty much know what you know, and being well-rested will help you think clearly, recall details, and avoid careless mistakes.
1)
![=(5 \times 10^3)+(2 \times 10^2)=(50 \times 10^2)+(2 \times 10^2)\\=10^2(50+2)=52 \times 100 = 5200 = 5.2 \times 10^3](https://tex.z-dn.net/?f=%3D%285%20%5Ctimes%2010%5E3%29%2B%282%20%5Ctimes%2010%5E2%29%3D%2850%20%5Ctimes%2010%5E2%29%2B%282%20%5Ctimes%2010%5E2%29%5C%5C%3D10%5E2%2850%2B2%29%3D52%20%5Ctimes%20100%20%3D%205200%20%3D%205.2%20%5Ctimes%2010%5E3)
2)
3) Yes, dilating with a scale factor that is less than 1 (and greater than 0) corresponds to a decrease.
4) Yes, dilating with a scale factor greater than 1 corresponds to an increase.
5) To find the slope of a scatter plot, you need to make a line of best fit, that is, the line that passes through as many points as possible and has about as many points above it as below it. Then, find two of those points that the line passes through and calculate the slope between those points. For two points
![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
and
![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
, the slope is
![m= \dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%20%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
.
This is an estimate. To find a better approximation, you can use the least-square method, but I think that probably involves higher-level math that you don't need. If you think you do need to solve it this way, just comment here and I'll explain it. Note that you can also calculate it using Microsoft Excel or a regression plot on a graphing calculator.
There is a 50% chance Jarius will pick an even number.
Explanation:
3/6 tiles are even numbers. That means 1/2 of the tiles are even numbers or .5. .5 is the same as 50% so Jarius has a 50% of picking a even number.
Hope this helps!
