Step-by-step explanation:

If Jen has 72 green marbles, then she has 81 purple marbles.

If Jen has 8 green marbles for every 9 purple marbles, then the ratio of green marbles to purple marbles is 8:9.

If Jen has 72 green marbles, we can use this ratio to determine how many purple marbles she has.

Let's set up a proportion

8/9 = 72/x

where x is the number of purple marbles Jen has.

To solve for x, we can cross-multiply:

8x = 9 × 72

Multiply the terms

8x = 648

Move 8 to right hand side

x = 648 / 8

Divide the numbers

x = 81

Answer:

The brain of the newborn baby has a mass of about 377 grams.

Step-by-step explanation:

Fractions are written as a ratio of two integers. For instance, a/b is a fraction.

Given the following parameters

Body mass = 2900 grams.

If the Brain mass of a newborn baby is about 13% of the mass of the newborn, then the mass of the brain is given as;

mass of brain = 13% of 2900

Mass of brain = 0.13 * 2900

Mass of brain = 377grams

Answer: 1.64. To find the difference in orders of magnitude between the two distances, we first need to convert both distances to the same unit of measurement. We'll convert both distances to kilometers.

The distance from Boone to Charlotte is already in kilometers, so we don't need to do any conversion for that distance.
The distance from Boone to Anchorage is in miles, so we'll need to convert that distance to kilometers. To do this, we'll multiply the number of miles by the conversion factor 1.61 km/mi:
4,212.7 mi × 1.61 km/mi = 6,782.45 km

Now that both distances are in kilometers, we can compare them to find the difference in orders of magnitude. An order of magnitude is a factor of 10, so we'll divide the larger distance by the smaller distance and then take the base 10 logarithm of the result:
log10(6,782.45 km / 156.6 km) = log10(43.3) ≈ 1.64
So the distance from Boone to Anchorage is about 1.64 orders of magnitude larger than the distance from Boone to Charlotte.

The measure of each angle of the triangle is 30 degrees, 60 degrees, and 90 degrees.

Let's assume that the three angles of the triangle are x, 2x, and 3x, respectively. We are given that these angles are in the ratio of 1:2:3. This means that:

x : 2x : 3x = 1 : 2 : 3

To solve for x, we need to add the three angles together and equate them to 180 degrees (since the sum of the angles in a triangle is 180 degrees). Therefore:

x + 2x + 3x = 180

6x = 180

x = 30

Now that we know the value of x, we can substitute it back into our original equation to find the measure of each angle. Therefore:

First angle: x = 30 degrees

Second angle: 2x = 60 degrees

Third angle: 3x = 90 degrees

There are 360 permutations of 4 item programs for a teacher's program.

A permutation is an arrangement of items in a specific order. To find the number of permutations of 4 items from a set of 6 items, we can use the formula:

nPr = n! / (n-r)!

Where n is the total number of items, r is the number of items we want to choose, and n! is the factorial of n (n * (n-1) * (n-2) * ... * 1).

Plugging in the given values, we get:

6P4 = 6! / (6-4)!

= 6! / 2!

= (6 * 5 * 4 * 3 * 2 * 1) / (2 * 1)

= 720 / 2

= 360

Therefore, there are 360 permutations of 4 item programs for a teacher's program.

So the length of the shorter diagonal is 3 inches. The length of the longer diagonal is  7 inches.

Let d1 and d2 be the lengths of the longer and shorter diagonals, respectively. We know that d1 = d2 + 4, and that the area of the rhombus is given by A = (d1*d2)/2 = 10.5.

Substituting d1 = d2 + 4 into the area equation, we get:

(d2+4)*d2/2 = 10.5

Multiplying both sides by 2 and simplifying, we get:

d2²+ 4d2 - 21 = 0

Using the quadratic formula, we can solve for d2:

d2 = (-4 ± [tex]\sqrt{4^2-4(-21)}[/tex]/2

d2 = (-4 ± [tex]\sqrt{100}[/tex]  /2

d2 = (-4 ± 10)/2

d2 = -7 or 3

Since the length of a diagonal cannot be negative, we reject the negative solution and conclude that d2 = 3. Therefore, d1 = d2 + 4 = 7, and the length of the longer diagonal is 7 inches.

The required equation of the line in slope-intercept form is y = 2x + 24.

To find the slope-intercept form of a line, we need to use the formula: y = mx + b

Where "m" is the slope and "b" is the y-intercept.

Here,

To find the slope of the line passing through the two given points (-2,20) and (-1,22), we can use the slope formula:

m = (y₂ - y₁) / (x₁ - x₁)

where (x₁, y₂) = (-2,20) and (x₁, y₂) = (-1,22).

m = (22 - 20) / (-1 - (-2))

m = 2 / 1

m = 2

Now that we have the slope, we can use one of the given points and the slope to find the y-intercept. Let's use the point (-2,20):

y = mx + b

20 = 2(-2) + b

20 = -4 + b

b = 24

The equation of the parabola in intercept form is y = -6(x+ 16 )(x + 2).    

A parabola is a type of curve that is formed when a point called the focus moves along a straight line called the directrix.

In other words a parabola is defined as the set of all points in a plane that are equidistant to the focus and the directrix.

The shape of a parabola is similar to a U or a V shape, and it can either be open upwards or downwards, depending on the orientation of the curve.

The Intercept form of a parabola is given by

                             y = a(x - p)(x - q)  

Where p and q are the x - coordinates at which the parabola crosses the x-axis (i.e, the x-intercepts).

Here we have

The parabola in intercept form that passes through (-18,72) with x-intercepts of -16 and -2

Let y = a(x-p)(x-q) is the equation of parabola    

From the data, x-intercepts p = - 16 and p = -2

=> y = a(x+ 16 )(x + 2)  ---- (1)

Given that the parabola passes through (-18, 72)

=> 72 = a(- 18 + 16 )(-8 + 2)  

=> 72 = a(-2)(-6)  

=> 72 = - 12a

=>  a = - 6

Substitute a = -6 in equation (1)

=> y = -6(x+ 16 )(x + 2)        

Therefore,

The equation of the parabola in intercept form is y = -6(x+ 16 )(x + 2).

You are correct that one way to simplify a payoff table is to reject dominated or inadmissible actions.

This means identifying choices that should not be made because there are other choices that are always better.

To determine if an action q is dominated by another action r, we can compare the payoffs for each state of the world j (from 1 to S) for both actions. If the payoff Cij for action q is less than or equal to the payoff Caj for action r for all j, and there is at least one value of j for which Cij is less than Caj, then action q is dominated by action r.

In other words, if there is another action that always has a higher payoff than action q, regardless of the state of the world, then action q is dominated and should not be chosen.

By rejecting dominated actions, we can simplify the payoff table and focus on the remaining actions that have the potential to provide the highest payoffs. This can help us make more informed decisions and choose the best course of action.

The greatest common factor (GCF) of the polynomial ab+8a+2b+16 is 2.

To factor the given polynomial ab + 8a + 2b + 16 by grouping, follow these steps:

1. Group the terms in pairs: (ab + 8a) + (2b + 16).

2. Factor out the Greatest Common Factor (GCF) from each group. - For the first group (ab + 8a), the GCF is "a". So, factor out "a" from the group: a(b + 8).

-For the second group (2b + 16), the GCF is "2". So, factor out "2" from the group: 2(b + 8).

3. Notice that both groups have a common factor of (b + 8). So, factor out (b + 8) from the entire expression: (b + 8)(a + 2).

Thus, the factored form of the polynomial ab + 8a + 2b + 16 by grouping is (b + 8)(a + 2).

The initial value obtained using the slope-intercept relation is 3 gallons.

We need to obtain the rate of change which gives the amount of gas entering into his car per second :

Rate of change = Rise / Run

Rate of change = - 11 - 3) / (48 - 0)

Rate of change = 8/48 = 1/6 gallons

Using the slope intercept relation :

y = bx + c

b = slope ; c = initial amount of gas

Choosing any pair of (x, y) point on the table :

(0, 3)

3 = 1/6x + c

3 = 1/6(0) + c

3 = 0 + c
