This question is incomplete.
The complete question says;
The two-way table shows the number of hours students studied and whether they studied independently or with a study group.
What is the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently?
a) 0.4 c) 0.25
b) 0.33 d) 0.11
Table is attached as image
Answer: C (0.25)
The number of students that studied for more than 2 hours as given in the table are 4.
The total number of people that studied independently include those that studied less than 2 hours and those that studied for more than 2 hours.
Those that studied less than 2 hours independently are 12.
Those that studied more than 2 hours independently are 4.
Hence the total number of people that studied independently is 16.
Therefore the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently would be = 4/16 = 1/4 = 0.25.
Answer:
8
Step-by-step explanation:
3 times 4 is 12 and 2 times 4 is 8
Answer:
112 <u>62</u> <u>174</u>
<u>8</u> 78 <u>86</u>
120 140 260
Step-by-step explanation:
You can solve this problem easily by looking at the total amounts compared to the information you already have. Once you do this, you can simply subtract them from each other to find the first two empty boxes, then you can just add across for the totals for the boxes on the right.
Answer:
The slope is ![-\frac{2}{11}](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B11%7D)
Step-by-step explanation:
Let
and ![(x_2,y_2)=(11,-3)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%2811%2C-3%29)
The slope is given by;
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We plug in the values to get;
![m=\frac{-3-3}{11--22}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-3-3%7D%7B11--22%7D)
Simplify;
![m=\frac{-6}{33}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-6%7D%7B33%7D)
![m=-\frac{2}{11}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B2%7D%7B11%7D)
Answer:
2x+30 = 90
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+30 = 90
