The probability of the sum of 5 is 5/20 or 1/4.
Solution:
Formula: P(A) = No. of favorable outcomes / Total no. of possible outcomes
P(A) = 5/20
P(A) = 1/4
You would need a reflection to create the same shape because a reflection is a flip meaning that the one in the front is showing the reflection
Answer:
3x²
Step-by-step explanation:
f(x) + f(x) + f(x) = x² + x² + x² = 3x²
The answer is d 1 in = 4m
Answer:
The ratio of the perimeter of ABCD to JKLM is;
b. 3/5
Step-by-step explanation:
Given that ABCD ~ JKLM, where;
DC and ML are corresponding sides
AD and JM are corresponding sides
AB and JK are corresponding sides
Therefore;
DC/ML = AD/JM = AB/JK
Plugging in the values of the variables gives;
9/15 = z/10 = x/12
∴ z = 10×9/15 = 6
x = 12×9/15 = 7.2
9/15 = 6/y
y = 6 ×15/9 = 10
The perimeter of the quadrilateral ABCD = AB + BC + DC + AD
∴ The perimeter of the quadrilateral ABCD = 6 + 6 + 9 + 7.2 = 28.2
The perimeter of the quadrilateral JKLM = JK + JM + ML + LK
∴ The perimeter of the quadrilateral JKLM = 12 + 10 + 15 + 10 = 47
The ratio of the perimeter of ABCD to JKLM = 28.2/47 =0.6 = 3/5.
