<h3>
Answer: 3/56</h3>
========================================================
Work Shown:
A = event of picking the "2" card
P(A) = probability of event A happening
P(A) = 1/8
This is because there is one card labeled "2" out of 8 cards total
-------
B = event of picking a number less than 6, given event A has happened
P(B) = 3/7
There are 3 cards less than 6 (those cards are labeled 3,4, and 5) out of 8-1 = 7 cards left over. We havent put the first card back so that's why 8 drops to 7. We also don't consider the "2" card. So that's where the 3/7 comes from.
-------
P(A and B) = P(A)*P(B)
P(A and B) = (1/8)*(3/7)
P(A and B) = (1*3)/(8*7)
P(A and B) = 3/56
Answer:
- 5
Step-by-step explanation:
"I am a negative integer greater than -6."
This eliminates any number that is less than -6, as well as any positive number.
0 > x > -6
"I am less than -2."
This narrows down the possible numbers to:
-5, -4, -3.
"I am not equal to -2 + (-1)"
-2 + - 1
-2 - 1
- 3
The number is not '-3'.
"I am not equal to 2 - 6."
2 - 6
- 4
The number is not -4.
Your number should be -5.
Hope this helps.
Answer:
- i
Step-by-step explanation:
Given
Multiply numerator/ denominator by i
= [ i² = - 1 ]
=
= - i
Answers
b = 2.77 m
A = 43.0°
C = 111.1°
cosine law to find b
b = 2.7708\ m
Find angle A with sine law
Find C with angles in triangle sum to 180
A + B + C = 180
C = 180 - A - B
C = 180 - 43.0467020 - 25.9
C = 111.1
Answer:
B
Step-by-step explanation:
p(x) = x² - 2√2x + 1
p(2√2) = (2√2)² - 2√2*2√2 + 1
=2²*(√2)² - 2*2*√2*√2 + 1
= 4 *2 - 4*2 + 1
= 8 - 8 + 1
= 1
