Think of the decimals in the probability column as percentage. So Micheal has a 30% chance of eating the next fry, Lidia would have a 10% chance, so on and so forth.

The percentage will always go up to 100%.

You're given the other people's percentages, but not Ronald.

So in order to find out the answer, add all of the people's numbers, and subtract by one.

dudee 4 months ago you asked this question I feel bad.

Step-by-step explanation:

1) The Equation to represent the situation is

     x+ x/3 + x/3-4 + 2( x/3 - 4)= 72

2) Alita is 16 years old

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the age of Dawn be x.

then age of Erik = x/3

Now, Jiro is 4 years younger then Erik.

Jiro's age = x/3 - 4

and, Alita is 2 times as old as Jiro.

So, Alita's age be = 2( x/3 - 4)

As,  The sum of all their ages is 72.

x+ x/3 + x/3-4 + 2( x/3 - 4)= 72

x+ x/3 + x/3-4 + 2x/3 - 8 = 72

7x/3 - 12 = 72

7x/3 = 84

x = 36

Thus,

Alita is 16 years oldJiro is 8 years oldErik is 12  years oldDawn is 36 years old

Which image below is an acute triangle?

Triangle A has angles measuring ninety five degrees, forty five degrees, and thirty degrees. Triangle B has angles measuring one hundred degrees, twenty five degrees, and twenty five degrees. Triangle C has angles measuring fifty degrees, sixty five degrees, and sixty five degrees. Triangle D has angles measuring thirty degrees, one hundred ten degrees, and twenty degrees.

A. Triangle A
B.Triangle B
C. Triangle C
D. Triangle D

Answers

Answer:

Triangle C.

Step-by-step explanation:

Acute triangles are triangles that have acute angles. Acute angles are angles that are less than 90 degrees.

Triangles A, B and D all have at least one angle that is greater than 90 degrees. Triangle C is the only triangle that has all acute angles, therefore it is an acute triangle.

Triangle C is an acute angle triangle.

The correct option is (C).

What is a Triangle?

A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

As per the given data:

The values for all the angles in Triangle A, Triangle B and Triangle C is given.

To find out the acute angle triangle, if all angles is a triangle are lesser than 90°, then it's an acute angle triangle.

Triangle A:

95° > 90° {not acute}

45° < 90°

30° < 90°

This is not an acute angle triangle.

Triangle B:

100° > 90° {not acute}

25° < 90°

25° < 90°

This is not an acute angle triangle.

Triangle C:

50° < 90°

65° < 90°

65° < 90°

This is an acute angle triangle.

Triangle D:

30° < 90°

110° > 90° {not acute}

20° < 90°

This is not an acute angle triangle.

Hence, Triangle C is an acute angle triangle.

Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.

His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.

In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.

what is d

Answers

Answer:

d=32!!!

Step-by-step explanation:

So first rewrite it as an equation: d/4+12=20

d/4+12=20 then subtract 12 from both sides to balance the equation

d/4=8 so multply both sides by 4  to isolate the variable, 4(d/4)=d =d and 8x4=32, so d=32

Answer:

d = 32

Step-by-step explanation:

Given

[tex]\frac{d}{4}[/tex] + 12 = 20 ( subtract 12 from both sides )

[tex]\frac{d}{4}[/tex] = 8 ( multiply both sides by 4 to clear the fraction )

d = 32
