Answer: 44 17/20

This is super easy

Let me explain it in an understanding matter

To find average we need to add the 2 numbers then divide by the amount of numbers there is which is 2.

So the first step is to add 2 3/5 and 87 1/10

The answer to that is 89 7/10

Lastly we need to divide 89 7/10 by 2

The answer to that is 44 17/20

So your answer should be 44 17/20

(I know that's not an answer choice, But that's how i see this question)

AlekseyPX

To answer the question, divide the fiber intake during breakfast by the total fiber intake prescribed by the doctor and multiply with 100%. With the given above,

(4 / 25) x 100% = 16%

Thus the fiber intake during breakfast constitutes 16% of the total fiber intake.

What geometric figure is also known as flat two-dimensional shape which only has length and width?

Jobisdone [24]

<u>Solid figure</u><u> is also known as flat </u><u>two-dimensional</u><u> shape which only has length and width.</u>

Geometrically figure , 2-dimensional shapes or objects are flat planar figures with two dimensions—length and width.
Shapes that are two-dimensional, or 2-D, have only two faces and no thickness.
Two-dimensional objects include a triangle, circle, rectangle, and square.

What geometric figure is also known as a flat?

A closed two-dimensional, or flat, figure is called a plane shape.
Different plane shapes have different attributes, such as the number of sides or corners (or vertices).
A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet.

What geometric figure is also known as?

Geometric figures are often classified as space figure, plane figure, lines, line segments, rays, and points depending on the dimensions of the figure.

V / -0.8 +14=39 plssss help this is literally so hard

Nat2105 [25]

<h2><u>Answer:</u></h2><h2> $\boxed{\boxed{\sf~v=-20}}$ </h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Subtract 14 from both sides:</h3>

$14-14=$ Cancels Out

$39-14=25$

<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>

<u>Equation at the end of Step 1: </u>

$v$ ÷ $-0.8=25$

<h3>2.) Multiply both sides by −0.8:</h3>

$-0.8$ × $-0.8=$ Cancels Out

$25$ × $-0.8=-20$

What is the probability that she chose the four students so that exactly ONE of them is a junior?

8090 [49]

Answer:

B) 0.246

Step-by-step explanation:

The desired probability is the sum of the probabilities of each of the ways one junior can be chosen. If we let a, b, c, d represent the ratio of juniors in classes 1 to 4, then this probability is ...

p(1 junior) = (a)(1-b)(1-c)(1-d) + (1-a)(b)(1-c)(1-d) + (1-a)(1-b)(c)(1-d) + (1-a)(1-b)(1-c)(1-d)

We can simplify this a little bit to ...

p(1 junior) = (1-a)(1-b)(1-c)(1-d) × (a/(1-a) +b/(1-b) +c/(1-c) +d/(1-d))

___

So, for {a, b, c, d} = {9/15, 12/15, 6/15, 3/15} = {3/5, 4/5, 2/5, 1/5} the probability of interest is ...

p(1 junior) = (2/5·1/5·3/5·4/5) × (3/2 + 4/1 + 2/3 + 1/4) = 24/625 × 77/12

p(1 junior) = 154/625 ≈ 0.246

_____

<em>Comment on the sum we're computing</em>

Each of the probabilities in the first sum above is ...

p(junior in given class) · p(not a junior in the other 3 classes)
