Answer:
a) 30% probability that it will not be colder today than it was yesterday
b) 90% probability that it will not be warmer today than it was yesterday
Step-by-step explanation:
In this question, we have that:
0.1 = 10% probability it will be warmer today than yesterday.
0.7 = 70% probability it will be colder today than yesterday.
a .What is the probability that it will not be colder today than it was yesterday?
70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.
b What is the probability that it will not be warmer today than it was yesterday?
10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday
Answer: 60
Step-by-step explanation: -4x-15=60
Y-y1=m(x-X1) is the formula.
m is the slope and the y1 and x1 are your points.
leave x and y; the ones without the 1 and solve for y
Answer:
The larger the sample size, the more accurate the estimation of the true population value.
Step-by-step explanation:
- As large will be the sample size more data will be shown and more are the c c changes of it being an estimate of a true population. The sample size can be determined on the basis of use of experience, target variance, confidence level, and target for power.
8 = x / 12.8
102.4 = x
Therefore x = 102.4
