The z score associated with the highest 10% is closest to: option (c) 1.28

-To find the z score associated with the highest 10%, first determine the percentage that corresponds to the lower 90%, since the z score table typically represents the area to the left of the z score.

- Look up the 0.90 (90%) in a standard normal distribution  (z score) table, which will give you the corresponding z score.

-The z score closest to 0.90 in the table is 1.28, which corresponds to the highest 10% of values.

Therefore, the z score associated with the highest 10% is closest to 1.28.

Organic firms are faster at responding to changing competitive demands.

An organic firm is an organization that makes use of a system in which the company is a living entity that changes as required by various situations. It depends on the situation, but the organic organization can be faster at responding to a changing competitive environment than a mechanistic organization. A mechanistic organization is one that works under the same old rigid structure and system, and they take longer to adjust to changing demands than an organic organization.

Organic organizations are more flexible than mechanistic organizations, so they can adjust more quickly to changing demands. Organic organizations have a more relaxed and informal structure. They work better in changing environments and can also respond more quickly to the changes. Their structure is such that they can delegate and decentralize more readily than mechanistic organizations.Therefore, it can be concluded that organic firms are faster at responding to changing competitive demands.

The value of P(R = 3) is 0.2854

Probabilities are used to determine the chances of events.

The given parameters are:

The probability that the ball lands on a red slot is calculated as:

\(p = \frac{18}{38}\)

Simplify

\(p= \frac{9}{19}\)

The probability that the ball does not land on a red slot is calculated as:

\(q = \frac{18+2}{38}\)

\(q = \frac{20}{38}\)

Simplify

\(q = \frac{10}{19}\)

The value of P(R = 3) is then calculated using the following binomial probability formula

\(P(R = r) = ^nC_rp^rq^{n-r}\)

Where:

\(n = 7\)

\(r = 3\)

So, we have:

\(P(R = 3) = ^7C_3 \times (9/19)^3 \times (10/19)^{7-3}\)

\(P(R = 3) = 35 \times (9/19)^3 \times (10/19)^4\)

\(P(R = 3) = 0.2854\)

Hence, the value of P(R = 3) is 0.2854

Answer:

As the lines are parallel, it shows that the two lines form 180° because they are angles on the same side of the transversal. A transversal is a line that bisects two lines.

Here,

(20x + 5)° + (24x - 1)° = 180°

=> (20x + 24x)° + (5 + (-1)  )° = 180°

=> 44x° + 4° = 180°

=> 44x = (180 - 4)°

=> x = 176 / 44

=> x = 4

Therefore, x = 4 is the solution of the equation.

Answer:

a.The number of cubes with edge length 1/2 cm that fit in this prism= 2520

b. Volume of the prism= 315 cm³

Step-by-step explanation:

Volume of the rectangular prism =  length *width * height

                                  = 7 1/2 * 12 * 15 1/2

                                  = 7 * 6* 15 1/2

                                  = 7*3*15

                                  = 315 cm³

Volume of the cube =  length *width * height

                                 = 1/2 *1/2 *1/2

                                   = 1/8 cm³

Now number of cubes that would fit in the rectangular prism is given by

   =  Volume of the prism/ Volume of the cubes

     = 315/1/8

      = 2520

The number of cubes with edge length cm that fit in this prism= 2520

Therefore , the solution of the given triangle comes out to be  AC = 10 units and PD = 6 units.

Triangles, which have three sides and three angles, can be made by joining any three points in a plane. They are among the earliest geometric shapes to be studied. Triangles are especially important since they may be divided into each polygon, whether it has four, five, six, or n sides.

Here,

Let AD and DC are 2x and x respectively.

We have, BC = 10 units

=> 2x =10

=> x = 10/2

=> x= 5

Now ,

=> AP + PF = 8 + y

=> 8 + y = 12

=> y =4

Therefore , the solution of the given triangle comes out to be  AC = 10 units and PD = 6 units.

Among the provided options, the most accurate statement would be:      "It unites many different Arabic cultures against a common enemy, the Jews."

The creation of the nation-state of Israel in 1948 led to increased Pan-Arabism in several ways. Firstly, the establishment of Israel as a Jewish state in the heart of the Arab world was perceived by many Arabs as a direct threat to their own national aspirations. This common enemy, the Jews, served as a rallying point that united various Arabic cultures against a perceived external threat.

Additionally, the existence of Israel became a central issue for Arab nationalism, with the goal of liberating Palestine from Israeli control becoming a unifying cause among Arab nations. The Arab-Israeli conflict and ongoing tensions between Israel and its Arab neighbors further fueled Pan-Arab sentiment.

It is important to note that the other options provided do not accurately reflect the impact of Israel's creation on Pan-Arabism. The creation of Israel did not justify Jewish expansion into the Sinai Peninsula, nor did it lead to Israeli-Palestinian unity after the Yom Kippur Wars.

The statement that it demonstrated the need for an Arabic homeland is also not accurate, as the creation of Israel was not a direct factor in the Arab world's pursuit of national self-determination.

If the bases are the same, subtract the exponents.

Remember to flip the exponent and make it positive, if needed."

Some information that someone might use to solve problems related to a circle design is the Tangent Arc theorem.

The tangent arc theorem states that if an angle is formed by two secants, one secant, one tangent, or two tangents, and also intersects in a space outside of the circle, then the value obtained will be equal to the difference of the values of the intercepted arcs divided by one and a half.

Also, note that angles outside a circle are those whose vertex or arc is pointed outwards and their sides are either secants or tangents. With this information, it will be possible to solve problems related to tangent lines and arc measures.

Answer: 72.97 Minutes

Step-by-step explanation: We have two cars, A and B, traveling along a straight road. Car A is moving at a constant speed of 77.0 km/h, while car B is moving at a constant speed of 114 km/h. At the starting point (t=0), car B is 45.0 km behind car A.

To figure out how long it takes for car B to catch up and overtake car A, we need to consider their relative speeds. The relative speed is the difference between the speed of car B and the speed of car A.

Relative speed = Speed of car B - Speed of car A

Relative speed = 114 km/h - 77.0 km/h

Relative speed = 37.0 km/h

So, car B is moving 37.0 km/h faster than car A. Now, we need to determine the time it takes for car B to cover the initial distance between them, which is 45.0 km.

To calculate time, we use the formula: Time = Distance / Speed. In this case, the distance is 45.0 km, and the speed is the relative speed of 37.0 km/h.

Time = 45.0 km / 37.0 km/h ≈ 1.2162 hours

Now, let's convert the time to minutes by multiplying it by 60 (since there are 60 minutes in an hour).

Time = 1.2162 hours * 60 minutes/hour ≈ 72.97 minutes

Therefore, it takes approximately 1.2162 hours or 72.97 minutes for car B to catch up and overtake car A.

Hope this helps!

1. Cell phone A charges at a rate of 33% every 30 minutes, which means it charges at a rate of 1.1% per minute (33%/30min = 1.1%/min).

Cell phone B's charging rate is not given for all times, but we can use the two data points in the table to estimate its charging rate.

From 0 to 12 minutes, the battery charges by 27%, which means it charges at a rate of 2.25% per minute (27%/12min = 2.25%/min). From 12 to 20 minutes, the battery charges by 18%, which means it charges at a rate of 1.5% per minute (18%/8min = 1.5%/min).

Therefore, cell phone B charges at a greater percentage rate than cell phone A between 0-12 minutes of being connected to the charger. After 12 minutes, cell phone A charges at a greater percentage rate than cell phone B.

2. Let's assume that cell phone B charges at a constant rate between 0-20 minutes. To find the charging rate, we can use the two data points in the table:

From 0 to 12 minutes, the battery charges by 27%. From 12 to 20 minutes, the battery charges by an additional 18%. So, in total, the battery charges by 45% in 20 minutes.

Using this information,

we can set up a proportion to find the time it will take cell phone B's battery to be 100% charged:

20min / 45% = x / 100%

Cross-multiplying, we get:

45x = 2000

Dividing by 45, we get:

x ≈ 44.44

Therefore, it will take approximately 44.44 minutes (rounded to the nearest hundredth) for cell phone B's battery to be 100% charged if it charges at a constant rate.
