The hypotenuse is √221.

To solve, use the Pythagorean theorem, a² + b² = c². <span>The variables <em>a</em> and <em>b</em> represent the legs of the triangle, and the variable <em>c</em> represents the hypotenuse. Plug in the known variables of <em>a </em>and <em>b</em>, and solve for <em>c</em>.

a = 10
b = 11

a</span>² + b² = c²
10² + 11² = c²
100 + 121 = c²
221 = c²
√221 = c

Hey!

You have to use the Pythagorean Theorem

a² + b² = c²

a = 10
10² = 10 × 10 = 100

b = 11
11² = 11 × 11 = 121

100 + 121 = 221

√221 = 14.9(rounded)

Answer ⇒ 14.9

Hope this helps! :)

What two numbers add to make 36 with one of the numbers being exactly twice the other?
11111nata11111 [884]

Answer:

12 and 24

Step-by-step explanation:

2 numbers, x in this case, with one being twice the other, one of them will be 2x, equals 36. Your equation would look like this: 2x+x=36. Simplify it to get 3x=36, divide the 3 and you get 12. 12 will be your small number then multiply by 2 to get your large one, 24.

On any given day, the probability that a large local river is polluted by carbon tetrachloride is 0.12. Each day, a test is cond
babymother [125]

Answer:

a) 0.2416

b) 0.4172

c) 0.0253

Step-by-step explanation:

Since the result of the test should be independent of the time , then the that the test number of times that test proves correct is independent of the days the river is correct .

denoting event a A=the test proves correct and B=the river is polluted

a) the test indicates pollution when

- the river is polluted and the test is correct

- the river is not polluted and the test fails

then

P(test indicates pollution)= P(A)*P(B)+ (1-P(A))*(1-P(B)) = 0.12*0.84+0.88*0.16 = 0.2416

b) according to Bayes

P(A∩B)= P(A/B)*P(B) → P(A/B)=P(A∩B)/P(B)

then

P(pollution exists/test indicates pollution)=P(A∩B)/P(B) = 0.84*0.12 / 0.2416 = 0.4172

c) since

P(test indicates no pollution)= P(A)*(1-P(B))+ (1-P(A))*P(B) = 0.84*0.88+  0.16*0.12 = 0.7584

the rate of false positives is

P(river is polluted/test indicates no pollution) = 0.12*0.16 / 0.7584 = 0.0253
