Answer:
there are 600 cm in 6 meters
Answer: 600 cm
Step-by-step explanation:
100cm = 1 m
Then ? cm = 6m
Since cm is smaller than m, cm would need more to be equal or equivalent to m. Therefore we say, what multiply by 1m gives you 6m? Because they are asking for 6m. Whatever you do to one side you do to the other.
6(100)cm = 6(1) m
600cm = 6m
Solve the inequality.
Answer:
y > 9
Step-by-step explanation:
Given inequality:
To solve the given inequality, we need to isolate y on one side of the equation.
Begin by multiplying both sides of the inequality by 3 to eliminate the fraction on the right side:
Now, divide both sides of the inequality by -8 to isolate y. Remember to reverse the inequality sign, as we are dividing by a negative number.
Therefore, the solution is:
Answer:
The answer is 2
Step-by-step explanation:
Use a calculator.
Answer:
71.63 kilowatts hours
Step-by-step explanation:
We are told in the question:
John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour.
We are to find, How many kilowatt hours can he use and keep his monthly cost no more than $109.
Step 1
$109 - $20.90
= $88.1
$88.1 is the amount left to spend on killowatts of electricity per hour after removing the normal monthly electricity bill in a month
Step 2
$1.23 = 1kilowatts per hour
$88.1 = y kilowatts per hour
Cross Multiply
= $1.23 × y kilowatts per hour = $88.1 × 1 kilowatts per hour
y kilowatts per hour = $88.1 × 1 kilowatts per hour/ $1.23
= 71.62601626kilowatts hour.
Approximately = 71.63 kilowatts hour
Therefore, John can use 71.63 kilowatts per hour and keep his monthly cost no more than $109
Answer:
71
kilowatt hours can he use and keep his monthly cost no more than $109
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 0, negative 20 and 4, 10.
b) Response bias
c) Non-response bias
d) Selection bias
Answer: Selection bias
Step-by-step explanation:
From the question, we are informed that a travel agency contacted a department store and obtained the list of all people who made purchases using their credit cards at the store in the last month. The agency then surveyed a random sample from the list, calling them to ask their preference for air travel or train travel for taking holidays.
The bus depicted above is referred to as the selection bias. The selection bias is simply a bias that is introduced when the sample obtained is not a representation of the population that the researcher wants to analyze. Here, the study population doesn't represent the target population.
The list gotten was for the people who made purchases using their credit cards but the agency used the list to determine the preference for air travel or train travel for taking holidays. This shows selection bias.
