The smallest sample observation that can increase 8.1 without changing the sample median's value is 4.4.

The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory. It could be referred to as "the middle" value for a data set. Simply expressed, the sample median is the middle value after sorting the observations in ascending order if the sample size is odd. The sample median is the average of the two middle values if the sample size is equal. The data set's median value is the value that falls in the middle, ordered by magnitude. The sample median is the average of the two middle terms when the number of samples in the data set is even. When the data set is symmetrically distributed, the sample mean serves as a reliable indicator of the central tendency.

The median can be calculated as (12.5+12.6)/2=12.55.

The incremented least observed value is 12.5-8.1=4.4, and the difference is that.

Step-by-step explanation:

a) He will start 900 feet from the edge

b) 16 Round trips are needed to cover the field.

Because Mr. Johns intends to check a wheat field 960 feet wide for weeds so he will distribute a 60-foot wide strip using a high clearance sprayer that has two 30-foot booms.

a) 960 foot - 60 foot = 900 foot

Therefore, he should start 900 feet from the edge.

b) 960 foot / 60 foot = 16 Trips.

Therefore, 16 round trips are needed to cover the field.

Answer:

-20

Step-by-step explanation:

By checking the piecewise function and evaluating it at x = 1, the result of the piecewise function is equal to - 4.

Piecewise functions are functions formed by several expressions constrained by intervals in the real set. In this case we find a piecewise functions consisting in two expressions constrained by two intervals in the real set. The piecewise function is defined by these expressions:

Then, we need to evaluate the piecewise function at x = 1. By direct inspection, we conclude that the value according to the piecewise function evaluated at x = 1 is equal to - 4.

Jack can use 3 3/14 feet of Barb wire used for each foot when he has 150 feet of barb wire which needs to be put on 35 3/4 feet of fencing.

We are given that:

Jack has 150 feet of Barb wire.

The fencing is:

35 3/4 feet that is equal to

= 140 / 3 feet

For each foot the Barb wire will be calculated by dividing the total Barb wire by the wire required for fencing.

So, we get that:

Barb wire used for each foot = 150 ÷ 140 / 3

Barb wire used for each foot = 450 / 140

Barb wire used for each foot =  = 45 / 14

Barb wire used for each foot = 3 3/14 feet.

So, Jack can use 3 3/14 feet of Barb wire used for each foot when he has 150 feet of barb wire which needs to be put on 35 3/4 feet of fencing.

The pharmaceutical company uses the quantitative variable to conducts an experiment.

Variables:

A variable is a characteristic of an object. Their values may occur more than once for a set of data. We consider just two main types of variables in this course.

Quantitative Variables - Variables whose values result from counting or measuring something.

Qualitative Variables - Variables that are not measurement variables. Their values do not result from measuring or counting.

Given,

A pharmaceutical company conducts an experiment in which a subject takes 75 mg of a substance orally.

And  the researchers measure how many seconds it takes for one quarter of the substance to exit the bloodstream.

Here we need to find the kind of variable is the company​ studying.

Here the company uses the Qualitative Variable because here they measure the effects of the medicine not the measurement.

So, the experiment uses the Qualitative Variable.

In order for the equations to have infinite amount of solutions, they have to be equal to each other.

A: 3x-1 doesn't equal 3x+1

B: 2x-1 is not equal to 1-2x since they negate each other.

The total length of the bridge built is less than the total length of the bridge.

We are given;

Length of bridge to be built per day = 54 feet

Number of days they built the bridge = 9 days

Thus, to find the total length that the bridge will span, we multiply the length built each day by the number of days. Thus;

Total Length of bridge = (54 * 9)

Total Length of bridge = 486 ft

Since we want to find if the bridge is at least 490 feet long. Thus, the total length of the bridge built is less than the total length of the bridge.

According to the statement if One x-intercept for a parabola is at the point (-4,0)  of the equation the other x-intercept for the parabola is (2, 0).

A parabola is an U-shaped mirror-symmetrical planar curve. It matches a variety of seemingly dissimilar mathematical formulations, all of which identify the same curves. A point and a line are two ways to describe a parabola.

Apollonius, who discovered numerous features of conic sections, is credited with the name "parabola." It signifies "application," referring to the "application of regions" notion, which, as Apollonius demonstrated, has a connection with this curve. Pappus is responsible for the focus-directrix attribute of the parabola as well as other conic sections.

As we first choose a cluster of the store before surveying all of the customers present in the store, they employed cluster sampling in this instance.

A population is divided into several clusters that are representative of homogeneous traits and have an equal chance of being included in the sample using the sampling technique known as cluster sampling.

Cluster sampling using a single stage: As the name implies, sampling only happens once.

Two-stage cluster sampling: In this case, a small number of individuals are chosen from each group by means of systematic or simple random sampling rather than the entire cluster.

Multiple stage cluster sampling: Compared to two stage sample, multiple stage cluster sampling goes one or more steps beyond. Complex clusters must be formed in order to conduct effective research across several geographies, and this can only be done by employing the multiple-stage sampling technique.

The total balance remaining on Joshua's game card is $4.5. So, the correct option is (A).

In the Question, It is given that Joshua purchase a game card for $18 which makes the Balance Bal = $18 on his card.

Now, He played 2 rounds of Basketball hoop and each costs $3.25 which makes total for Basketball B = 2*3.25 => B = $6.25

And, He played 4 rounds of Air Hockey each game cost $1.75 which makes the total for Air Hockey A = 4*1.75  => A = $7

To calculate the remaining balance on his card we need to subtract these games' costs from the balance on his card :

=> T = Bal - B - A, Where T = Total, Bal = Balance on card, B = Basketball, A = Air Hockey

=> T = 18 - 6.25 - 7    => T = $4.5

Hence, the Total balance remaining on his card T = $4.5
