Answer:

B. 11 feet

Step-by-step explanation:

<h2><u>Finding the length </u></h2><h3><em><u>area of a square is length ^2</u></em></h3>

the length on each side of a square is equal .

we can use this formula to get the length of each side:

$length^{2} = 121$

can find the length by square rooting the 121

$\sqrt{121}$

length = 11

<h3><u>answer = B. 11 feet </u></h3>

What expressions equal to 1 forth of 52

Klio2033 [76]

Remember that x/4 and 1/4*x is the same thing.

1/4*52 is therefore the same as 52/4. Fractions represent division, so 52 divided by 4 is also correct.
0.25*x is the same as 1/4*x because 1/4=0.25
4% of 52 is incorrect because the decimal form of 4% is 0.04, which is not the same as 0.25

Final answer: B

Answer:

g(5) = 5

Step-by-step explanation:

g(5) is really g when x=5 so we have to use the function g(x) when x≥2

g(5) = 2x-5 when x=5

g(5) = 2*5 -5 = 10-5 = 5

In testing the lethal concentration of a chemical found in polluted water. it is found that a certain concentration will kill 20

sasho [114]

Answer:

a) 0.1091

b) 0.9994

c) 0.5886

Step-by-step explanation:

X = the number of fish out of 20 that die after 24 hours

x = 0, 1, 2, . . . , 20

X~ Binomial (n= 20, p =0.20)

P(14 survive) = P(X = 6)

= $nC_r p^r q^{n-r}= 20C_6 0.2^6\times0.8^{14}$ =0.1091

Similarly we can find out

P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994

P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
