Marvin had 2 spools of thread. Each spool contained 10 1/2 yards of thread. Marvin used 4 yards from each spool. How many yards of thread did Marvin have left

Answer:  4 hours and 10 minutes per week

Step-by-step explanation:

She exercises for 5 days per week (week days only).

(5/6 hr/day) x 5 days = 25/6 = 4.17 hours = 4 hours and 10 minutes per week

10 units is the length of the line segment

Given that: the graph of the line segment from negative 6 comma negative 5 to 0 comma 3. Thus:

point 1 (-6, -5) => x1 = -6, y1 = -5

point 2 (0, 3) => x2 = 0, y2 = 3

Length of x-axis (x): x2 -x1 = 0-(-6) = 6

Length of y-axis (y): y2 -y1 = 3-(-5) = 8

Let the length of the line segment be L

Using Pythagorean Theorem:

L² = x² + y²

L² = 6² + 8²

L² = 36 + 64

L² = 100

L = √100 = 10 units

Therefore, the length of the line segment is 10 units. The 3rd option is the answer

Ratio is the relation between two amounts that shows the number of times one value contains within the other.

What is Ratio?

A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of vegetables contains eight tomato and six carrots, the tomato-to-carrot ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the proportion of carrots to tomato is 6:8 (or 3:4), while the proportion of tomato to overall fruit is 8:14. (or 4:7). A ratio's numbers can be any quantity, such as a count of persons or things, or measures of lengths, weights, time, and so forth. In most situations, both numbers must be positive.

The half life for this radioactive substance is 40.76 years

As we know that radioactive decay is a first order reaction

For first order reaction, we can write

N = [tex]N^{0}[/tex][tex]e^{-kt}[/tex]

Where N = Amount of substance at time ‘t’

N0 = Initial amount of substance

K = rate constant for first order reaction

t = time in years

Now, as per the question,

This substance is decaying at a rate of 1.7% that means 98.3% will remain after decaying.

For time t = 1 years , N/[tex]N^{0}[/tex] = 0.983

Therefore, we have

N/[tex]N^{0}[/tex] = [tex]e^{-kt}[/tex]

0.983 = [tex]e^{-k }[/tex]

-k = ln(0.983)

-k = -0.017

K = 0.017 [tex]year^{-1}[/tex]

Now for half life, We can write N/[tex]N^{0}[/tex] = 0.5

Therefore, N/[tex]N^{0}[/tex] = [tex]e^{-kt}[/tex]

              0.5 = [tex]e^{-0.017t}[/tex]

ln(0.5) = -0.017t

-0.693 = -0.017t

A geometric sequence is a series in which each term is found by multiplying the preceding term by the same value. Its general term is. aₙ= a₁rⁿ⁻¹.

The example of a geometric sequence with 5 as initial term is

5, 10, 20, 40.....

In an arithmetic sequence, the difference between consecutive terms is always the same.

aₙ = a + (n - 1)d

There is a total of 190 ways to share apples between them.

What is a ball-and-urn method?

The ball-and-urn method often referred to as stars-and-bars, sticks-and-stones, or dots-and-dividers is a typical combinatorial method.

It is used to resolve issues of the following type: in how many different ways can one divide 'k' undifferentiable items into 'n' distinct bins?

Use the ball-and-urn method,  Let Alice get 'x' apples, Becky get 'y' apples, and Chris get 'z' apples.

⇒x + y + z = 24

We can manipulate this into an equation that can be solved using the ball-and-urn method

All of them get at least 2 apples, so we can subtract 2 from x, 2 from y, and 2 from z.

⇒(x - 2) + (y - 2) + (z - 2) = 18

Let x' = x - 2, y' = y - 2, z' = z - 2.

⇒ x' + y' + z' = 18

We can allow either of them to equal 0, hence this can be solved by the ball-and-urn method.

By the ball-and-urn method, we get

 [tex]$\binom{18 + 3 - 1}{3 - 1} = \binom{20}{2} = \ 190}$.[/tex]

The standard deviation of X is about 2.38.

Suppose X is normally distributed with mean of 5. If P (X ≤ 3) = 0.2

We need to find the standard deviation of X

We can use a z-table or a graphing calculator to find the z-value that is associated with a probability to 0.20 (you should get a z-value of about z = -0.84). Then use the z-value formula

z = (x−μ) /σ

−0.84 = (3−5) /σ

−0.84 = −2/σ

σ = -2/-0.84

σ  = 2.38

Solving for the standard deviation ( σ ) you should get a value of about 2.38. Therefore, the standard deviation of X is about 2.38.

We know very well that Probability is the defined  as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We need to take care that each vertex of convex pentagon has been assigned a color.

We are given that we can choose 6 colors , and we need to take care that the ends of each diagonal must have different colors.

So, we need to try all different combinations,

Let PQRST are the vertex of the pentagon.

Let vertex P be any vertex, then vertex Q be one of the diagonal vertices to P, R be one of the diagonal vertices to Q, and so on. We consider cases for this problem.

In the case that,

R has the same color as P,

S has a different color from P

and so,

T has a different color from P and S.

In this case, the choices are

P = 6

Q = 5

R = 1

S = 5

T = 4

So, total number of combinations are =6 x 5 x 1 x 5 x 4 = 600 combinations.

Similarly, R has a different color from P and

S has a different color from P,

In this kind of situations,

P has 6 choices,

Q has 5 choices,

R has 4 choices

S has 4 choices,

and T has 4 choices,

So, total number of combinations  is

=> 6 x 5 x 4 x 4 x 4 = 1920

Next case,  R has a different color from P and S has the same color as P, So,

P has 6 choices,

Q has 5 choices,

R has 4 choices,

S has 1 choice, and

T has 5 choices,

=> total number of combinations=6 x 5 x 4 x 1 x 5 = 600

The given expression 3x + 2.5 (4x + 2) is equivalent to 13x + 5.

The given question is a polynomial in one variable. Polynomials in one variable are algebraic expressions that depend on only one variable. The given expression is also dependent only on the variable, x.

In order to find its equivalent, we need to expand it. To expand it, we multiply the terms inside the bracket with the 2.5 outside. By doing so, we will get -

= 3x + (2.5*4x) + (2.5*2)

= 3x + 10x + 5
