The most probable color marble which could be picked up without looking is red colored marble because there quantity is comparatively higher than others.

As per the data given, the probability that the specific colored balls are picked up is given. So depending upon the total number of balls be any number x, then the number of red balls is half of the total balls, blue balls is quarter of total balls, green balls is one sixth of total balls and yellows balls are one twelfth of total balls.

Hence, yellow balls are least in number and red colored balls are higher in number and hence the probability that a red colored ball is picked up first is 1/2*100 = 50%.

So Mackenzie runs approximately 4.5 miles in an hour (rounded to nearest tenth of a mile)

The approximate length of the midsegment parallel to xy is 6.63

The midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle and has the same length as each of the two sides.

To find the midpoint of a line segment, we average the x-coordinates and the y-coordinates of its endpoints.

Since the question stated that the midsegment is parallel to xy, we need to find midpoint of xw and yw.

First, let's find the midpoint of side xw:

Midpoint of xw : ((-14+10)/2, (20+4)/2) = (-2, 12)

Midpoint of yw : ((-14-2)/2, (20-4)/2) = (-8, 8 )

The length of a line segment between two points (x1, y1) and (x2, y2) in a two-dimensional coordinate system can be calculated using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Length line of midpoint xw and midpoint yw :

√((-2-(-8))^2 + (12-(8))^2) = √(6^2 + 4^2) = √(36 + 8) = √44

So, the length of the midsegment is parallel to XY, which is approximately equal to √44 = 6.63

ΔWCO and ΔPIG are congruent by SSS.

Option B is the correct answer.

There are ways to prove that two triangles are congruent.

- Side-Side-Side (SSS) Congruence.

The three sides of one triangle are equal to the corresponding three sides of another triangle.

- Side-Angle-Side (SAS) Congruence.

The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.

- Angle-Side-Angle (ASA) Congruence.

The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.

- Angle-Angle-Side (AAS) Congruence.

We have,

From ΔWCO and ΔPIG

The ratio between the corresponding sides is same.

i.e

WC/GP = WO/GI = 7/21 = 5/15 = 1/3

Now,

Since the ratio of the two corresponding sides in the two triangles are same,

The ratio of the remaining corresponding sides will also be the same.

Now,

C0 = IP = 1/3

So,

ΔWCO and ΔPIG are congruent by SSS.

Thus,

ΔWCO and ΔPIG are congruent by SSS.

Answer:

x=70

y=55

Step-by-step explanation:

We can start by finding the opposite angle to 125.

180-125=55

We would use 180 because a line is a straight angle, therefore if you intercept the line both angles would add up to 180.

55 is y because they are equivalent.

the sum of all the angles is always 180 so...

55+55=110

180-110=7

b) The flowerbed is 433 feet away from the hive.

In accordance with the statement, the bee flies from its hive to a flowerbed, stays 11 minutes and flies back to the hive, which means that the bee takes 2 minutes on covering twice the distance between the hive and the flowerbed. Given that the bee flies at constant speed, then we can use the following formula:

2 · d = 20 · t + 13 · (2 - t)

2 · d = 7 · t + 26

d = (7 · t + 26) / 2

d = (7 · 120 + 26) / 2

d = 433 ft

Step-by-step explanation:

The volume of the tetrahedron is 1.0667 cubic units.

The tetrahedron is enclosed by the coordinate planes and the plane 10x + y + z = 4.

To find the volume of the tetrahedron using a triple integral, we can use the following bounds:

0 ≤ z ≤ 4 - 10x - y

0 ≤ y ≤ 4 - 10x

0 ≤ x ≤ 0.4

This is because the tetrahedron is bound by the coordinate planes, so x, y, and z all must be positive, and the plane 10x + y + z = 4 sets the upper bound for z and y, and the upper bound for x is simply where the plane intersects the x-axis (which can be found by setting y and z equal to 0 and solving for x).

The triple integral to find the volume of the tetrahedron is then:

V = ∫∫∫ dV = ∫0^0.4 ∫0^(4-10x) ∫0^(4-10x-y) dz dy dx

Evaluating this integral, we get:

V = ∫0^0.4 ∫0^(4-10x) (4-10x-y) dy dx

= ∫0^0.4 [4y - 10xy - (1/2)y^2]0^(4-10x) dx

= ∫0^0.4 [4(4-10x) - 10x(4-10x) - (1/2)(4-10x)^2] dx

= ∫0^0.4 (-25x^2 + 20x + 8) dx

= [-25/3 x^3 + 10 x^2 + 8x]0^0.4

= 1.0667

Therefore, the volume of the tetrahedron is approximately 1.0667 cubic units.

Answer:

We can use the sine law to find h. First, we determine the angle between the line of sight and h:

180 - 90 - 39 = 51 degrees

The sine law states that the ratio of one triangle's angle to the opposite side's length is the same as another angle to its opposite side's length, so we can solve for h as follows:

h/sin(39) = 500/sin(51)

h = 500*sin(39)/sin(51)

When we round to the nearest whole number, we get h = 405 ft.

Answer:

Step-by-step explanation:

The angle bisector of a triangle divides the opposite side in 2 segments that are proportional to the other 2 sides of the triangle. Namely:

\(\frac{15}{18}=\frac{w}{30}\) and cross multiply.

18w = 450 so

w = 25

It is possible for the sample mean height for young men to be at least 2 inches greater than the sample mean height for young women, but it is not necessarily surprising.

There are biological and environmental factors that can affect height, such as genetics, nutrition, and exercise. Men tend to be taller than women on average due to genetic and hormonal differences.

                                         Additionally, men may engage in more physical activity or consume more protein, which can contribute to their height.

                                       However, it is important to note that a difference of 2 inches in sample means does not necessarily imply a significant difference in population means. Statistical analysis, such as hypothesis testing, would be needed to determine the significance of this difference.

Two blue = 6

Step-by-step explanation:

Let r = red

Let b = blue

2r + r + b = 21

r - b = 3    Can we rewritten  r = 3 + b  Substitute 3 + b  for r into the first equation

2r + r + b = 21

2(3 + b) + 3 + b + b =  21   Distribute the 2

6 + 2b + 3 + b + b = 21  Combine like terms

9 + 4b = 21  Subtract 9 from both sides

9 - 9 + 4b = 21 - 9

4b = 12  Divide both sides by 4

\(\frac{4b}{4}\) = \(\frac{12}{4}\)

b = 3

2 blues would equal 6.

Answer:

6

Step-by-step explanation:

Define the variables:

From the given blackboard, create a system of equations from the first three equations:

\(\begin{cases}3x + y = 21\\\;\:x - y = 3\\2x + y = 15\end{cases}\)

Add the first equation to the second equation to eliminate y:

\(\begin{array}{lrcccr}& 3x & + & y & = & 21\\+ & (x & - & y & = & 3\\\cline{2-6} &4x &&&=&24\end{array}\)

Solve the equation for x:

\(\implies \dfrac{4x}{4}=\dfrac{24}{4}\)

\(\implies x=6\)

Substitute the found value of x into the second equation and solve for y:

\(\implies 6-y=3\)

\(\implies y=3\)

Therefore, the value of the red pencil is 6 and the value of the blue pencil is 3.

Finally, substitute the found value of y into the last equation:

\(\implies 3 + 3 = \boxed{6}\)
