This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture. Thus, option (D) is correct.
Event - 1: Choosing a letter from the alphabet that is Q.
Let us assume the probability of happening of event 1 is P(Q).
Event - 2: Choosing a digit from 0-9 that is 7.
Let us assume the probability of happening of event 1 is P(7).
Now, we need to choosing the secret code that is 7Q.
We need to multiply both events to get the desired result.
Thus,
This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture.

Answer:
Option 4: P(7∩Q) = P(7) × P(Q)
Step-by-step explanation:
P(7∩Q) represents the probability of choosing the secret code "7Q".
If A and B are independent events, then,
P(A∩B) = P(A) × P(B)
Let A be the event of choosing a number from 0-9 and
B be the event of choosing an alphabet.
Clearly, A and B are independent.
Therefore,
P(7∩Q) = P(7) × P(Q)
Answer:
x=8
Step-by-step explanation:
This isosceles triangle is composed of two right triangles with sides 8, , and y
As we have two sides of a right triangle, we can find the third using the Pythagorean Theorem
As this is an isosceles triangle, these two right triangles are equal, this means that x=2y
Therefore, x=2(4)=8
Answer:
x=8
Step-by-step explanation:
Answer:y=3
Step-by-step explanation:
Answer:(0,5)
Step-by-step explanation:
Y-3=2(x+1)
Rewrite it
2(x+1)=y-3
Sub. 0 for xto find y
2=y-3
Y-3=2
Y=2+3
Y=5
5-3=2(x+1)
2=2x+2
2x+2=2
2x=-2+2
2x= 0
X=0
To check
5-3=2(0+1)
2=2(1)
2= 2
It checks

B.
27 yd²
C.
18 yd
D.
18 yd²
