From Environment Canada: "Our experts on weather and climate have combed through 45 years of weather records, and determined the

probabilities based on the following criteria:
-a "white" Christmas is defined as having at least 2 cm of snow on the ground on December 25."
The probability that there will be a white Christmas in Vancouver is 11%.
The probability that there will be a white Christmas in Hamilton is 68%
What type of probability have they used to determine these probabilities?

kvasek [131]

Answer:

76.16 kilograms of food

Step-by-step explanation:

Number of cyclist = 32

Food per cyclist = 8.33 kilograms

Days of the trip = 7 days

Food per cyclist per day = 8.33 kg / 7

= 1.19kg food per day for each cyclist

how many kilograms of food will the group be carrying at the end of Day 5?

5 days out of 7 days = 2 days

Each cyclist will have to carry = 2 × 1.19 kg of food for the remaining two days

= 2 × 1.19

= 2.38 kilograms of food for two days

32 cyclist for 2 days = 32 × 2.38 kg of food

= 76.16 kilograms of food

The group will be carrying 76.16 kilograms of food at the end of Day 5

A programmer plans to develop a new software system. In planning for the operating system that he will​ use, he needs to estimat
Contact [7]

Answer:  a. n= 1068

b. n= 164

Step-by-step explanation:

The formula to find the sample size :

n=p(1-p)(\dfrac{z^{*}}{E})^2

, where p=prior population proportion , z* = critical z-value and E = Margin of error.

Here , let p=proportion of computers that use a new operating system.

Given : Confidence level = 95%

i.e. z* = 1.96  [by z-table]

Margin of error : E = 3% =0.03

a. If p is unknown , then we assume p=0.5

Then, n=(0.5)(1-0.5)(\dfrac{1.96}{0.03})^2=1067.11111\approx1068

i.e. n= 1068

b. p=0.96

Then, n=(0.96)(1-0.96)(\dfrac{1.96}{0.03})^2=163.908266667\approx164

i.e. n= 164.
