Answer:
Required probability is 0.3025.
Step-by-step explanation:
Given that probability of landing heads up in a toss of bent coin = 0.55
Then probability of getting head in 1st toss = 0.55
2nd toss is independent of the first toss.
Then probability of getting head in 2nd toss = 0.55
Hence probability of getting head in two tosses of the coin = (0.55)(0.55) =0.3025
Hence required probability is 0.3025.
Answer:
3
Step-by-step explanation:
To find the rate of change we: divide the change in y (output) by the change in x (input).
A = (-3 - 0) / (0 - 1) = -3 / -1 = 3

Answer:
24 cars
Step-by-step explanation:
out of 80 toys, 3/5 are buses- 80 * 3/5 is 48 so there are 48 buses
80 - 48 is 32, 32 of the rest of the toys are cars and bikes
we know that there are 3 times as many cars than bikes, so to find out how many cars and bikes there we can do 3n + n, where n is the number of bikes it also equals 4n
32 = 4n; n = 8
there are 8 bikes, so there are 24 cars
Answer:
A. 0.0625
B. 0.1089
C. 0.81
D. 0.0196
Step-by-step explanation:
The proportion of variance is shared by the two correlated variables is given as the r².
Therefore,
For A. r = 0.25
Proportion of variance is shared by the two correlated variables = 0.25²
= 0.0625
For B. r = 0.33
Proportion of variance is shared by the two correlated variables = 0.33²
= 0.1089
For C. r = 0.90
Proportion of variance is shared by the two correlated variables = 0.90²
= 0.81
For D. r = 0.14
Proportion of variance is shared by the two correlated variables = 0.14²
= 0.0196
