If a student was randomly guessing while completing a 20 question multiple choice exam, what is the probability they would score
mario62 [17]

Answer:

you want 4 correct and 16 incorrect

there are 20 questions

each question has four answers, so

P(right answer) = 1/4

P(wrong answer) = 3/4

----

Since you want 4 correct of 20 we have a combination of 20C4

This is a binomial problem where p = 1/4, q = 3/4 and we get

(20 "choose" 4)*(probability correct)^(number correct)*(probability incorrect)^(number incorrect)

putting numbers in we get

(20c4)*(1/4)^4*(3/4)^16

This gives us

~ .189685

The money m (in £) Xavier has to spend each week is his wage w (in £) subtract the tax t (in £) he pays on his income. Enter a f
Otrada [13]

Answer: The answer is given below

Step-by-step explanation:

From the question, we are informed that the money m (in £) Xavier has to spend each week is his wage w (in £) subtract the tax t (in £) he pays on his income. Therefore, the formula for the money he can spend will be:

m = w - t

The amount of money that he has to spend if he earns £120 a week and pays £41 in tax will be:

m = w - t

m = £120 - £41

m = £79

Find the value of x and y
Romashka [77]

Step-by-step explanation:

\triangle ABC \sim\triangle DEF..(Given)  \\ \therefore \frac{AB}{DE} =\frac{BC}{EF}=\frac{AC}{DF}..(CSST)\\\\\therefore \frac{6}{4} =\frac{7}{x}=\frac{8}{y}\\\\ \therefore \frac{6}{4} =\frac{7}{x} \\ \therefore \: x =  \frac{7 \times 4}{6}  \\  \\\therefore \: x =  \frac{28}{6} =  \frac{14}{3}    \\  \\ \huge \red{ \boxed{ \therefore \: x =  \frac{14}{3} }} \\   \\  \because \: \frac{6}{4} =\frac{8}{y} \\  \\ \therefore \:y =  \frac{4 \times 8}{6}  \\  \\ \therefore \:y =  \frac{32}{6}  \\  \\ \huge \purple{ \boxed{ \therefore \:y =  \frac{16}{3}  }}\\  \\
