1 as they flipped a 6 sided cube and want to know the probability of rolling a 5
6-5=1
The answer is 1
Answer:
19.44
Step-by-step explanation:
We have the following information:
3 red balls, 5 green balls, and 1 yellow ball
In total there are 3 + 5 + 1 = 9 balls.
We calculate the probability of each:
Network: 3/9
Green: 5/9
Yellow: 1/9
Each one corresponds a price in profit or losses:
Network: 4
Green: -3
Yellow: 10
So in total it would be the sum of the multiplication of the probability and the price and then multiply everything by 25:
(4 * 3/9 + -3 * 5/9 + 10 * 1/9) * 25 = (0.777) * 25
= 19.44
Answer:
Step-by-step explanation:
In a geometric sequence, the nth term is
T_n = ar^(n-1)
a = first term
r = common ratio which can be gotten by dividing second term by first term, third term by second term etc
Therefore
a = 16
r = -3.2 ÷ 16
r = -0.2
T_7 = ar^(7-1)
T_7 = ar^6
T_7 = 16[(-0.2)^6]
T_7 = 16(0.000064)
T_7 = 0.001024
Answer: 0.57
Step-by-step explanation:
Given : The speed of cars on a stretch of road is normally distributed .
Population Mean = 
Standard deviation : 
Let x be the random variable that represents the speed of cars on a stretch of road .
z-score : 
For x= 50.
By using the standard normal distribution table ,
The probability that a randomly selected car is violating the speed limit of 50 miles per hour :-
Answer:
Step-by-step explanation:
Basically we want to find x and then plug that in for angle B. How do we find x? Well, we know the angles are complimentary, which means theya dd to 90, so let's start with that.
A + B = 90
8x - 28 + 8x + 22 = 90
16x -6 = 90
16x = 96
x = 6
So there we go. Now to find B
B
8x+22
8(6)+22
48 + 22
70
