Answer:

x=40°

Step-by-step explanation:

Since the 2 sides of the triangle are equal, the angles are also equal. 180-110=70 so to find the angle measurement of x we have 180-70-70=40 x is 40°

With θ in quadrant III, we expect to have both cosθ and sinθ negative. Then from the Pythagorean identity, we get

[tex]\cos^2\theta+\sin^2\theta=1\implies\sin\theta=-\sqrt{1-\cos^2\theta}=-\dfrac{\sqrt{35}}6[/tex]

Then from the definition of tangent, that is

tanθ = sinθ / cosθ

we get

[tex]\tan\theta=\dfrac{-\frac{\sqrt{35}}6}{-\frac16}=\boxed{\sqrt{35}}[/tex]

The value of [tex]\tan \theta[/tex] is required.

The required value in quadrant three is [tex]\tan\theta=\sqrt{35}[/tex]

[tex]\cos \theta=-\dfrac{1}{6}[/tex]

We have the identity

[tex]\tan \theta=\dfrac{\sqrt{1-\cos^2\theta}}{\cos \theta}\\\Rightarrow \tan\theta=\dfrac{\sqrt{1-\left(-\dfrac{1}{6}\right)^2}}{-\dfrac{1}{6}}\\\Rightarrow \tan \theta=\dfrac{\sqrt{\dfrac{35}{36}}}{-\dfrac{1}{6}}\\\Rightarrow \tan\theta=\pm\sqrt{35}\times -1\\\Rightarrow \tan\theta=\pm\sqrt{35}[/tex]

The required value in quadrant three is [tex]\tan\theta=\sqrt{35}[/tex]

Answer:

The man has been dead for 9 days. This is because this is the only day on the chart where all the types of insects coexist.

Step-by-step explanation:

5 species of insects were found at the same time alive on the dead man's body.

These 5 insects are then sent to the lab to be studied and larvae/eggs from them, raised under similar conditions to the conditions of the dead body.

The activity the eggs are them studied and presented in the chart provided

Insect/Day 1 2 3 4 5 6 7 8 9 10

Blowfly 1 1 1 1 1 1 1 1 1 0

Species A 0 0 0 0 1 1 1 1 1 1

Species B 0 0 0 0 0 0 1 1 1 0

Species C 0 0 0 0 0 0 0 0 1 1

Species D 0 0 0 0 0 1 1 1 1 1

Note that 0 represents a non-activity on the part of the egg of the insect specie.

From the chart, the first time all 5 insects coexist together at the same time just like they were found in the dead body is on the 9th day. Before the 9th day, all 5 insects do not coexist at the same time and even beyond the 9th day, on the 10th day, insect specie B stops existing.

So, it is evident that the man has been dead for 9 days as that's the only day on the chart where all the types of insects coexist.

Answer:Half of the diameter so d/2 or distance from the midpoint to the circle border

Step-by-step explanation:c=2pie•r^2

Answer:

A park ranger at a large national park wants to estimate the mean diameter of all the aspen trees in the park. The park ranger believes that due to environmental changes, the aspen trees are not growing as large as they were in 1975. (a) Data collected in 1975 indicate that the distribution of diameter for aspen trees in this park was approximately normal with a mean of 8 inches and a standard deviation of 2.5 inches. Find the approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches.

Step-by-step explanation:

Let X be a random variable which represents the diameters of aspan trees of a park in 1975.

Given that,  X ~ N(8, 2.52)

Mean (μ) = 8 inches

Standard deviation (σ) = 2.5 inches

We have to obtain P(X < 5.5 inches)

We know that if X ~ N(μ, σ²) then, X-M Z=1 ~ N(0,1)

P(X< 5.5) =    P( X- μ < 5.5 - μ)

                           σ         σ

P(X<5.5) = P(Z < 5.5 – 8  )

                               2.5

P(X<5.5) = P(Z < -1)

Using "pnorm" function of R we get, P(Z < -1) = 0.1587

:: P(X < 5.5) = 0.1587

The probability that a randomly selected Aspen  tree in the park in 1975 would have a diameter less than 5.5 inches is 0.1587.

Answer:

a) [tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

b) [tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

Step-by-step explanation:

For this case we have the following properties:

[tex] \mu = 8500, \sigma = 1500[/tex]

Part a

And for this case from the empirical rule we know that within one deviation from the mean we have 68% of the values , within two deviation 95% and within 3 deviations 99.7%. So then we can find the limits like this:

[tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

Part b

For this case we want to find this probability:

[tex] P(X<6000)[/tex]

We can calculate the number of deviation below the mean with the z score formula given by:

[tex] z = \frac{X -\mu}{\sigma}[/tex]

And replacing we got:

[tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

  1/16, 1/16

Step-by-step explanation:

Perhaps you want to complete the square. You do that by adding the square of half the x-coefficient:

  ((1/2)/2)^2 = (1/4)^2 = 1/16

The number to complete the square is 1/16. It is added to both sides of the equation to give ...

  x^2 +1/2x +1/16 = 2 +1/16

_____

Written as a square, the equation is ...

A. p + q = b

D. p · q = c

Step-by-step explanation:

It's best to look at an example, such as this:

[tex]x^2 - 12x+ 35[/tex]

And it's factored form is:

(x - 5) (x - 7)

As you can see, if you add -5 (p) and -7 (q), you get -12 (b). Then, if you multiply -5 (p) and -7 (q), you get 35 (c).

Probability = 0.25.

Step-by-step explanation:

The Important thing to note here is that we have sixteen(16) different possible outcomes for this particular problem or question.

From the question above, we are given the following information or data: ''bag contains four chips of different​ colors, including​ red, blue,​ green, and yellow. A chip is selected at random from the bag and then replaced in the bag. A second chip is then selected at random"

Hence, the sixteen (16) different possible outcomes are; RR, RB, BB, BR, RG, GR, GG, RY, YR, YY, BG, GB, BY, YB, GY, YG.

To calculate the probability we need to used the numbers of f different colors divided by the number big possible outcomes, that is; 4/16 = 0.25.

Probability that one blue chip and one yellow chip are  selected is 1/8

Given that a  bag contains four chips of different colors

The colors given are red , blue, green and yellow

A chip is selected at random from the bag and replaced in the bag

After that a second chip is selected at random.

In both the selections there is a equal probability of choosing any color chip at random

So  for the first chip the color can be either  blue , green red  or yellow.

Similarly for the second chip the color of the chosen chip can be either  blue , green , red or  yellow

We can make set of possible outcomes for the colors of chips in the first and the second draw

The number of possible outcomes are 16 in numbers

{ RR, RB, RG, RY. BR, BB, BG, BY, GR,GB, GG, GY, YR, YB, YG, YY}

Probability that one blue chip and one yellow chip are  selected is 1/8

Since there is only two such case.

Answer:

c. At a = .05, there is sufficient evidence of difference among at least two of the substandard work scale means for the four leadership styles.

Step-by-step explanation:

From the given output, df(Between)=3

df (Between) =k-1, where, k denotes number of groups. Therefore, k-1=3, k=4.

Thus the null hypothesis is as follows:

H0:mu1=mu2=mu3=mu4 (there is no difference in substandard work scale means for four leadership styles)

H1: At least one mean scale is different from another.

Per rule, reject H0, if p value corresponding to F test statistic is less than given level of significance, alpha=0.05.

Here, F(3, 56)=6.056, p<0.05 (the p value is 0.0012). Therefore, reject H0, and conclude that at least one substandard work scale mean of a leadership is significantly different from a substandard work scale mean of another leadership.
