Answer:

removing seed casings from grains
removing salt from seawater
water decomposing to oxygen and hydrogen
A soda bottle bubbling when it is opened

Explanation:

The mixing and separating actions been performed here involves the options selected, because before their can be separation there has to be some kind of mixing involved .

Removing seed casings from grains : as a grain crop grows and reproduces its produce which is the grain is attached to a casing that hold the seeds together( mixing ) therefore removing the casings from the grains ( separating ) is an example
Removing salt from seawater; At sea the water is mixed up with the salt content found/deposited at the bottom of the sea ( mixing ) removing the salt from the seawater ( separating ) is an example as well
water is made up of hydrogen and oxygen ( mixing ) decomposing water into oxygen and hydrogen is a form of separation
soda bottle bubbling when it is open is separating the gases used while producing the soda

copper is an element and not a compound so no mixing is involved

Dima020 [189]

Answer:

import random
states = {
"Alabama": "Montgomery",
"California": "Sacramento",
"Florida": "Tallahassee",
"Hawaii": "Honolulu",
"Indiana": "Indianapolis",
"Michigan": "Lansing",
"New York": "Albany",
"Texas" : "Austin",

}
correct = 0
wrong = 0
round = 1
while(round <= 5):
current_state = random.choice(list(states))
answer = input("What is the capital of " + current_state + ": ")
if(answer == states[current_state]):
correct += 1
else:
wrong += 1
round += 1
print("Correct answer: " + str(correct))
print("Wrong answer: " + str(wrong))

Explanation:

The solution code is written in Python 3.

Line 3 -14

Create a dictionary of US States with capital as each of their corresponding value. Please note only ten sample states are chosen here.

Line 16 - 18

Create variables to track the number of correct and inaccurate response and also round counter.

Line 19 - 28

Set the while condition to enable user to play the quiz for five questions and use random.choice to randomly pick a state from the dictionary and prompt user to input the capital of selected stated.

If the answer matched with the capital value of the selected state, increment the correct counter by one. Otherwise the wrong counter will be incremented by one. Increment the round counter by one before proceed to next round.

Line 30 - 31

Print the number of correct responses and wrong responses.

Of 500 sessions that occurred on a website during a one-week period, 200 of them started on the homepage; 100 of these 200 sessi

Elena L [17]

Answer:

the homepage bounce rate

Explanation:

Bounce rate is defined as the percentage of people that visits a page on a website and then exit or leave. That is, the visitors did not view any other page except the first one and they just leave the page after that visit. In order to get the bounce rate, the total number of visitors to a single page is taken and its then divided by the total number of visits to the website. For example, if the total number of visitors to a website over a period of time is 3000, while those that only visited a page on the website is 500, then the bounce rate is

(500/3000) * 100 = 16%

For this question, the homepage recorded 100 visited only once out of 200 which means homepage bounce rate is 50% : (100/200)*100

While website bounce rate is total number of bounces across the website/total visit to the website

100+100 =200 this is the total bounces across the website

200/500 :500 is the total visit to the website

(200/500)*100 = 40 %

Therefore the homepage bounce rate is higher than the site bounce rate
