A list of 6 one digit whole numbers with an average of 5, a median of 6, a range of 9, and no mode is

since the numbers will have no mode so they are all different

Assuming the numbers are: a, b. c. d. e. and f

The average is 5

(a + b + c + d + e + f ) / 6 = 5

a + b + c + d + e + f = 30

The median is 6

(c + d)/2 = 6

c + d = 12  (assume c = 5 and d = 7)

range is 9

f - a = 9, since it is a one digit number a range of 9 is possible for 9 - 0

hence a = 0 and f = 9

substituting assumed values to the average

0 + b + 5 + 7 + e + 9 = 30

b + e + 21 = 30

b + e = 9 (let b = 8and e = 1)

hence the numbers are

0, 1, 5, 7, 8, and 9

The abiotic factor that can prevent the organism from becoming preserved, AFTER it has been buried is groundwater.

An abiotic factor refers to a non-living component of an ecosystem that influences the survival and growth of living organisms.

Groundwater can cause the dissolution of minerals present in the sediment that encases the buried organism.

This process can lead to the destruction of the fossilized remains, as the minerals provide the framework for the preservation of the organism's hard parts (such as bones or shells).

Groundwater can also cause the erosion of the sediment, which can expose the buried remains and make them vulnerable to biotic factors such as scavengers, predators, and decomposers.

Predators and animals that eat bones, scavengers and plants that use the nutrients of fossils, and other animals of the same species as the organism that died are all biotic factors that can affect the preservation of the organism, but they do so before or during the burial process.

Step-by-step explanation:

\(\frac{1}{3} h + \frac{1}{2}h = 1\\\\\frac{2}{6} h + \frac{3}{6}h = 1\\\\\\\frac{5 }{6} h =1\\\\h=\frac{6}{5}\)

it would take Ted and Jacob 1.2 hours, or 1 hour and 12 minutes, to clear the field together.

Two or more expressions with an Equal sign is called as Equation.

Let's start by using the formula for the combined work of two people:

1/t = 1/3 + 1/2

Here, t represents the number of hours it would take to clear the field together.

To solve for t, we can first find a common denominator for the fractions on the right-hand side of the equation:

1/t = (2/6) + (3/6)

1/t = 5/6

To isolate t on one side of the equation, we can take the reciprocal of both sides:

t/1 = 6/5

t = 1.2

Therefore, it would take Ted and Jacob 1.2 hours, or 1 hour and 12 minutes, to clear the field together.

En route at FL290, the altimeter is set correctly, but not reset to the local altimeter setting of 30. 57" Hg during descent. If the field elevation is 650 feet and the altimeter is functioning properly, the approximate indication upon landing is 715 feet's.

Flight levels are used to provide safe vertical separation between aircraft despite natural variations in local atmospheric pressure. Historically, altitude was measured with a barometric altimeter, which is essentially a calibrated barometer. The altimeter measures ambient air pressure which, according to the barometric formula, decreases as altitude increases. The corresponding height is then calculated and displayed. If the altimeter calibrations of different aircraft are inconsistent, two aircraft may be flying at the same altitude even though their altimeters indicate they are at different altitudes.

Flight altitude solves this problem by defining altitude in terms of standard atmospheric pressure at sea level. All aircraft operating at flight altitude are calibrated to this setting, regardless of the actual pressure

To display true altitude, the pilot must calibrate the altimeter to the local atmospheric pressure at sea level to account for natural variations in atmospheric pressure over time and across a region.

The force exerted on the beam by support point 2 is approximately 186.4 N.

To solve this problem, we can use the principle of moments. The weight of the bowling ball and the mass of the beam are both forces acting on the beam. We can assume that the beam is in static equilibrium, meaning that the sum of the forces and moments acting on the beam is equal to zero.

First, we can calculate the weight of the bowling ball as 6.5 kg x 9.81 m/s^2 = 63.6 N. This weight acts downward at a distance of 2.7 m from support point 1, so it creates a clockwise moment of 63.6 N x 2.7 m = 171.7 Nm.

Next, we can calculate the moment created by the mass of the beam. We can assume that the mass is evenly distributed along the length of the beam, so the center of mass is at the midpoint of the beam, which is 1.5 m from support point 1. The mass of the beam is given as 18 kg + m kg, so we can write:

(18 kg + m kg) x 9.81 m/s^2 x 1.5 m = (18 kg + m kg) x g x 1.5 m

where g is the acceleration due to gravity (9.81 m/s^2). This moment acts counterclockwise, so it has a negative sign.

Finally, we can write the equation for static equilibrium:

ΣM = 0

where ΣM is the sum of the moments. This gives:

171.7 Nm - (18 kg + m kg) x g x 1.5 m - (m kg) x g x 0.75 m = 0

Solving for m, we get:

m = (171.7 Nm - 18 kg x g x 1.5 m) / (g x 0.75 m)

m ≈ 6.98 kg

Now that we know the mass of the beam, we can calculate the force exerted by support point 2 using the equation for static equilibrium:

ΣF = 0

where ΣF is the sum of the forces. This gives:

F2 - 63.6 N - (18 kg + 6.98 kg) x g = 0

Solving for F2, we get:

F2 ≈ 186.4 N

Therefore, the force exerted on the beam by support point 2 is approximately 186.4 N.

Baking cupcakes for the time suggested for baking a cake may result in overbaked and dry cupcakes.

This is because cupcakes are smaller and have less volume than cakes, so they require less baking time to cook through. Overbaking can also cause cupcakes to lose their moisture and become tough. It is important to follow the suggested baking time for cupcakes to achieve the desired texture and flavor.

To ensure that cupcakes are baked correctly, it is recommended to test them for doneness using a toothpick or cake tester. Insert the toothpick in the center of the cupcake, and if it comes out clean, the cupcakes are done.

If the toothpick has batter on it, the cupcakes need more time to bake. Adjust the baking time accordingly, and continue checking until the toothpick comes out clean.

The expected value of the treatment mean square for a completely randomized design experiment is given by E(MS Trt) = σ2 + m∑Ti2 / (L-1).

Let L be the number of treatments, and R be the number of replications per treatment.

According to the model, yij is the response from the jth replication of the ith treatment.

Therefore, the total number of observations is given by N = LR. Therefore, we assume the following linear model to estimate the treatment effects: yij=μ+Ti+Eij Where yij is the observed value for the jth replication in the ith treatment. μ represents the population mean.

Ti represents the effect of the ith treatment and is assumed to be a fixed effect. Eij is the error term for the jth replication of the ith treatment, and is assumed to follow a normal distribution with a mean of 0 and a variance of σ2.

We now turn to the analysis of variance for the CRD with L treatments and R replications per treatment.

The total sum of squares is given by: SST = ∑∑yij2 - (T..)2/N Where T.. is the total sum of observations.

It has (L-1)(R-1) degrees of freedom.

The total mean square is given by: MST = SST / (L-1)(R-1)

The treatment sum of squares is given by: SSTR = ∑n(T.)2/R - (T..)2/N Where T. is the sum of the observations in the ith treatment, and n is the number of observations in the ith treatment.

It has L-1 degrees of freedom. The treatment mean square is given by: MSTR = SSTR / (L-1)

The error sum of squares is given by: SSE = SST - SSTR It has (L-1)(R-1) degrees of freedom.

The error mean square is given by: MSE = SSE / (L-1)(R-1)

Therefore, E(MS Trt)=σ2+ m∑Ti2/t-1  since E(Ti)=0 for all i.

To show that E(MS Trt) = σ2 + m∑Ti2 / t-1

We start by using the definition of expected value E() to derive the expected value of the treatment mean square

(MS Trt): E(MS Trt) = E(SSTR / (L-1))

Next, we can express SSTR in terms of the Ti's as follows:

SSTR = ∑n(T.)2/R - (T..)2/N= 1/R ∑Ti2n - (T..)2/N

We can then substitute this expression into the expression for MS Trt:

MS Trt = SSTR / (L-1)

Substituting SSTR = 1/R ∑Ti2n - (T..)2/N, we get:

MS Trt = [1/R ∑Ti2n - (T..)2/N] / (L-1)

Simplifying the expression, we get:

MS Trt = [1/R ∑Ti2n] / (L-1) - [(T..)2/N] / (L-1)E(MS Trt)

= E([1/R ∑Ti2n] / (L-1)) - E([(T..)2/N] / (L-1))

Next, we can apply the linearity of expectation to the two terms:

E(MS Trt) = 1/(L-1) E[1/R ∑Ti2n] - 1/(L-1) E[(T..)2/N]

Simplifying the expression, we get:

E(MS Trt) = 1/(L-1) E(Ti2) - 1/(L-1) [(T..)2/N]

We note that E(Ti) = 0 for all i, since the treatments are assumed to have no effect on the population mean.

Therefore, we can simplify the expression further:

E(MS Trt) = E(Ti2) / (L-1) - [(T..)2/N] / (L-1)

Substituting the expression for Ti2 from the model, we get:

E(MS Trt) = σ2 + m∑Ti2 / (L-1)(R-1) - [(T..)2/N] / (L-1)

Simplifying the expression, we get:

E(MS Trt) = σ2 + m∑Ti2 / (L-1)

Since we have derived the expected value of MS Trt in terms of the Ti's, we can now use this result to derive E(MS Err). By definition, we have E(MS Err) = σ2.

Therefore, the expected value of the treatment mean square for a completely randomized design experiment is given by E(MS Trt) = σ2 + m∑Ti2 / (L-1). When Ti = 0 for all i, the treatments have no effect on the population mean, and hence all the observations will be independent and identically distributed with a common variance. Therefore, the experiment reduces to a randomized complete block design with one block, and the standard analysis of variance can be used to estimate the treatment effects.
