Answer: Multiply from left to right.
(-3/4)(-4/7)(-2/3)
3/7(-2/3)
-2/7
Step-by-step explanation:
Answer:
a) 2nd
b) 4.8
c) 4
Step-by-step explanation:
Mode is the highest frequency.
"Away" has highest frequency in the second quarter
Mean = sum/n
Sum of Home goals:
5+4+8+9 = 26
Sum of Away goals:
2+9+7+4 = 22
Total goals = 26+22 = 48
Average = 48/10 = 4.8
No. of home goals - No. of away goals
26 - 22 = 4
Answer:
the correct answer is d) i.e the above statement has a solution which is neither positive nor negative
because X+10=10
or,X=10-10
X=0
and 0 is neither positive nor negative
I believe it is y axis that it is reflected by
The length of the unknown sides of the triangles are as follows:
CD = 10√2
AC = 10√2
BC = 10
AB = 10
<h3>Triangle ACD</h3>
ΔACD is a right angle triangle. Therefore, Pythagoras theorem can be used to find the sides of the triangle.
where
c = hypotenuse side = AD = 20
a and b are the other 2 legs
lets use trigonometric ratio to find CD,
cos 45 = adjacent / hypotenuse
cos 45 = CD / 20
CD = 1 / √2 × 20
CD = 20 / √2 = 20√2 / 2 = 10√2
20² - (10√2)² = AC²
400 - 100(2) = AC²
AC² = 200
AC = √200 = 10√2
<h3>
Triangle ABC</h3>
ΔABC is a right angle triangle too. Therefore,
Using trigonometric ratio,
cos 45 = BC / 10√2
BC = 10√2 × cos 45
BC = 10√2 × 1 / √2
BC = 10√2 / √2 = 10
(10√2)² - 10² = AB²
200 - 100 = AB²
AB² = 100
AB = 10
