Given that <span>William guesses random answers for the last
four questions and that e</span><span>ach question has five answer choices.</span><span>
The probability that he gets an answer correct </span>is 1 / 5.
The probability that he did not get an answer correct is 4 / 5.
The probability that he will not get any of the 4 questions correctly is

Therefore, the probability that he gets at least one of the 4 questions correctly is
Speed = Distance ÷ time
Speed upstream = 84 ÷ 7 = 12 km/h
Speed downstream = 84 ÷ 3 = 28 km/h
Speed in still water = 1/2(28 + 12) = 20 km/h
Answer: 20 km/h

Answer:</h2>
The decimal point should be placed between digits 9 and 7 in the dividend. i.e the dividend becomes 269.7
<h2>
Step-by-step explanation:</h2>
Dividend = 26.97 [numerator]
Divisor = 6.3 [denominator]
If 26.97 ÷ 6.3 is written in long division form so that the divisor is written as a whole number, we have the following;
(i)First convert the divisor to a whole number by multiplying by 10 i.e
6.3 x 10 = 63
(ii) Since the divisor (denominator) has been multiplied by 10, to make sure the division expression stays the same, we need to multiply the dividend(numerator) too by 10. i.e
26.97 x 10 = 269.7
(iii) The division expression then becomes;
269.7 ÷ 63
Therefore, the decimal point should be placed between digits 9 and 7 in the dividend.
Answer:
congruent angle pair
Step-by-step explanation:
angles 2 and 3 are congruent(equal 90 degrees), and angles 3 and 6 are opposite each other, indicating that they are of equal measure. therefore, angles 2 and 6 and congruent.
