In a 30 60 90 triangle, hypotenuse = short leg *2.
Therefore it is 8
The statements that apply to the ratio of rice and water are:
- The ratio of rice to water is 1 to 2.5
- The ratio of water to rice is 2.5 to 1
<h3>Ratios</h3>
Ratios are used to compare quantities of different measurements
The entries on the table are given as:
<u>Rice Water</u>
2 5
3 7.5
5 12.5
8 20
<h3>The ratios of both quantities</h3>
The ratio (r) of rice and water is then calculated as:
Pick any corresponding table entry.
So, we have:
Divide
This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1

Answer:
AB
Step-by-step explanation:
If blood type is independent of gender then we must have for each blood type 50% males and 50% females
Let us compare with this view each blood type
A
Observed 105 93 198 105 93 198
Expected 99 99 198 99 99 198
(O-E)^2 36 36 72
(O-E)^2/E 0.363636364 0.363636364 0.727272727
B
Observed 105 93 198 99 84 183
Expected 99 99 198 91.5 91.5 183
(O-E)^2 56.25 56.25 112.5
(O-E)^2/E 0.614754098 0.614754098 1.229508197
AB
Observed 15 18 33
Expected 16.5 16.5 33
(O-E)^2 2.25 2.25 4.5
(O-E)^2/E 0.136363636 0.136363636 0.272727273
O
Observed 160 140 300
Expected 150 150 300
(O-E)^2 100 100 200
(O-E)^2/E 0.666666667 0.666666667 1.333333333
We find that the deviations are the least for blood group AB
So AB blood group is independent of gender
$ 10.50 divide by 5 b
<span>to find 25% of her hourly wage last year </span>
<span>Then multiply by 4 to find 100% of her hourly wage last year. </span>
<span>ex: $ 10.50 divide by 5 </span>
<span>= $ 2.10 </span>
