Answer:

Sampling bias

Step-by-step explanation:

Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.

The obtuse angles from the given list are D (between 90° to 180°) and E (111° angle). Thus, the answer is D, E.

The angles are given as follows:

A: less than 45°

B: greater than 270°

C: right angle

D: between 90° to 180°

E: A 111° angle

F: A 222° angle

G: A 0.180° angle

H: A 180.180° angle

To identify which angles are obtuse, we need to determine the angles that are greater than 90 degrees but less than 180 degrees.

Among the given angles:

A: less than 45° (not obtuse)

B: greater than 270° (not obtuse)

C: right angle (not obtuse)

D: between 90° to 180° (obtuse)

E: 111° angle (obtuse)

F: 222° angle (not obtuse)

G: 0.180° angle (not obtuse)

H: 180.180° angle (not obtuse)

Therefore, the obtuse angles from the given list are:

D (between 90° to 180°)

E (111° angle)

The answer is D, E.

Answer:

0.72

Step-by-step explanation:

Answer:

Step-by-step explanation:

100%-17.5%= 82.5%

82.5% (divide) 82.5%= 1%

so (1% of the orginal price)=

£264 (divide) 82.5%= £320= original price

The price of the computer is reduced by £56 which is 17.5% of £320.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The price of a computer is reduced by 17.5% and the reduced price is £264.

Let the original price be '£x'.

So, (100 - 17.5)% = 82.5% of '£x' is  £264.

∴ (82.5/100)×x = 264.

0.825x = 264.

x = 264/0.825.

x =  £320.

So, The price reduced is (320 - 264) =  £56.

Answer: 3 feet tall

Step-by-step explanation:

50% of something is also 1/2 of it. So if we multiply 2 by 1/2 or .5, we get 1. So then we take 1 and add it to 2 because it is 50% taller than what it used to be.

You will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Given that,

Room dimensions:

Length: 16 feet

Width: 10 feet

Height: 8 feet

Features on the walls:

Two windows:

Width: 2 feet

Height: 5 feet

One door:

Width: 4 feet

Height: 7 feet

Paint coverage:

1 gallon of paint covers 350 square feet

Calculate the area of the walls first:

Subtract the area of the windows and door area from the total wall area.

The total wall area is the sum of the areas of all four walls.

The area of each wall is calculated by multiplying the height of the room by its length.

So, the area of each wall = 8 feet (height) x16 feet (length)

The area of each wall = 128 square feet.

Calculate the area of the windows and the door.

The area of each window is calculated by multiplying its width by its height.

So, the area of each window = 2 feet (width) x  5 feet (height)

The area of each window = 10 square feet.

The area of the door is calculated by multiplying its width by its height. So,

The area of the door = 4 feet (width) x 7 feet (height)

The area of the door  = 28 square feet.

Now, subtract the total area of the windows and the door from the total wall area.

Total wall area = 4 walls x 128 square feet

Total wall area  = 512 square feet

The total area of the windows = 2 windows x 10 square feet

The total area of the windows = 20 square feet

The total area of the door = 1 door x 28 square feet

The total area of the door = 28 square feet

Area to be painted = Total wall area - Total area of the windows - Total area of the door

Area to be painted = 512 square feet - 20 square feet - 28 square feet

Area to be painted = 464 square feet.

Now, we can determine the number of gallons of paint needed.

Since 1 gallon of paint covers 350 square feet,

Divide the area to be painted by 350.

The number of gallons of paint needed = Area to be painted / Coverage per gallon

The number of gallons of paint needed = 464 square feet / 350 square feet/gallon

The number of gallons of paint needed ≈ 1.33 gallons.

Hence, you will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.
