Hannah estimated that a bottle could hold 2.2 liters. The actual volume of the bottle was 2 litters. What was the percent error in hannas measurements?

Answers

Answer:

I dont have a direct answer but i think i can help.

Step-by-step explanation:

For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.

The scale factor of a model plane to the actual plane is 1 to 20.
Find the wing area of the model if the wing area of the actual plane is 400 ft^2

Answers

Answer:

1 ft²

Step-by-step explanation:

The scale factor = 1 : 20

The area is the product of two dimensions, so the area of the model part to actual part is:

1 ² : 20 ² = 1 : 400

If the actual plane has wing area of 400 ft², then the model will have wing area:

400 ft² / 400 = 1 ft²

If an island only residents are penguins and beans and if there’s 18 heads and 50 feet on the island how many penguins in bears

Answers

let p = # of penguins and b = # of bears

p + b = 18 (both animals have 1 head)

2p + 4b = 50 (bears have 4 feet while penguins have 2)

We have a system of linear equations and can solve with elimination or substitution.

Using elimination,

2(p + b = 18) -> 2p + 2b = 36

Subtract this from the other equation to get

2b = 14 -> b = 7 (7 bears)

p = 18 - b -> p = 11 (11 penguins)

The mean can be misleading if you don't know the spread of data items. True or false...

Answers

Answer:

True

Step-by-step explanation:

When data is skewed toward the high or low end, the mean can be a misleading measure of central tendency.  In such a case the central tendency for the data items shifts toward either the high or low end -- away from the mean.  The median then becomes the better measure.

The mean could be misleading when we don't know the spread of data items is to be considered as the true.

Role of mean:

The mean do have the high impact on the extreme observations. In the case when the observation is high so automatically the remaining observations should be low due to which the mean should be increased.

So based on this, we can conclude that The mean could be misleading when we don't know the spread of data items is to be considered as the true.

A student graphs 5x−y=7 on a coordinate plane. Which equation, when graphed on the same coordinate plane, will result in a system of equations with no solution? 5x−y=7 5 x − − y = 7 5x−y=1 5 x − − y = 1 x−5y=35 x − − 5 y = 35 x−5y=5

Answers

Answer:

5x−y=1

Step-by-step explanation:

An equation is a statement that shows the equality between two expressions.

An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.

The equation after it is simplified would have the same coefficients and different constant.

Given:

5x−y=7

An equation that will result in a system of equations with no solution will have the same coefficient but different constant.  

Hence 5x−y=1, would give a system of equations with no solution.

Simplifying gives:

7 = 1 (no solution)
