Answer:
1/36 ≈ 0.028
Step-by-step explanation:
In order to get a total of 2 if you roll 2 dice, you have to roll two ones. (You can't roll a 0 and 2 because an average die does not have a zero on it)
You have a 1/6 chance to roll a 1 on the first die; and you have a 1/6 chance to roll a one on the second die.
To find the probability of this happening together you have to multiply them together.
1/6 * 1/6 = 1/36 = 0.0277778 ≈ 0.028
Answer:
63.57817848
Step-by-step explanation:
all will be in degrees:
cos 40 sinx - sin 40 cos x = sin(x - 40) by the formula sin(A − B) = sinA cosB − cosA sinB
sin(x - 40) = 2/5
x - 40 = arcsin(2/5)
x - 40 = 23.57817848
x = 63.57817848 degrees
Answer:f(0)=-3
Step-by-step explanation:
f(x)=3x-3
f(0)=3(0)-3
f(0)=0-3
f(0)=-3
Answer: use photo math
Step-by-step explanation: download an select type of math
Let the number of buses be x
and car be y
• Total vehicle gone are 21
x + y = 21 ..... ( i ) × 4
• There are 30 people in buses and 4 on car total people gone are 318
30x + 4y = 318 ..... ( ii )
Sub ( ii ) from ( i ) × 4
4x + 4y - ( 30x + 4y ) = 84 - 318
4x + 4y - 30x - 4y = - 234
- 26y = - 234
y = 9
Putting the value of y in eq i
x + y = 21
x = 21 - 9
x = 12
Total buses are 12
and total car are 9
Hope it helps...
