Step-by-step explanation:

Answer:

.2 Cm

Step-by-step explanation:

(a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, (d) boxplot is attached, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.

(a) The mean = sum of all values divided by the number of values

μ = (x1 + x2 + ..... + xn)/n

n = 20

μ = (0.0395 + 0.0443+ 0.0450 + ... + 0.0550 + 0.0571)/20

μ = 0.9878/20

μ = 0.0494

(b) Variance = sum of squared deviations from the mean divided by n-1

s² = {(x1-μ)² + (x2-μ)² + .... (xn - μ)²)/(n-1)

s² = {(0.0395-0.0494)² + (0.0443-0.0494)² + .... +(0.0571-0.0494)²}/19

s² = 0.000016

(b) The minimum is 0.0395 and the maximum is 0.0571.

since the number of data is even, the median will be the average of two middle values.

M = Q2 = (0.0496+0.0499)/2 = 0.04975

Now, the first quartile is the median of the data values below the median

so Q1 = (0.0470+0.0485)/2 = 0.04775

And third quartile will be the median of the data values above the median

Q3 = (0.0504+0.0516)/2 = 0.0510

(c) Since we know that the number of data values is even, the median will be the average of the two middle values of the data set

so M = (0.0496+0.0499)/2

or M = 0.04975

(d) The boxplot is at maximum and minimum values. It will start in Q1 and end in Q3 and has a vertical line at the median or Q2.

The boxplot is attached.

(e) The 5th percentile means 0.05(n+1)th data value

or = 0.05(20+1) = 1.05th data value

5th percentile = 0.0550 + 0.05(0.0443-0.0395) = 0.03974

similarly,

95th percentile = 0.0550 + 0.95(0.0571-0.0550) = 0.056995

Therefore, (a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.

The solution set of the given equation is x = 8.39 or x = -12.39

\( \frac{1}{4} {{(x + 2} )}^{2} = 27\)

cross product

\( {1} {{(x + 2}^{} )}^{2} = 27 \times 4\)

(x + 2²) = 108

find the square root of both sides

\( \sqrt{ ({x + 2)}^{2} } = ± \sqrt{108}\)

x + 2 = ± 10.39

So,

x = 10.39 - 2 or x = -10.39 - 2

x = 8.39 or x = -12.39

A population has a mean of 180 and a standard deviation of 36. A sample of 84 observations will be taken. The probability that the sample mean will be between 181 and 185 is

Given n(sample size) = 84

Population mean(μ) = 180

Standard Deviation(σ) = 36

Standard error of the mean = σx-bar = σ/√n = 36/√84 = 36/9.165 = 3.927

Standardizing the sample mean we have

Z = (x-bar - μ)/σx-bar = (x-bar - μ)/σ/√n

x-bar = 180

Z(x-bar=185 at point C) = (185 - 180)/3.927 = 5/3.927 = 1.273

Z(x-bar=181 at point D) = (181 - 180)/3.927 = 1/3.927 = 0.254

The area ABCD is the probability that the sample mean will lie between 181 and 185.

The shaded Area ABCD = (Area corresponding to Z = 2 or x-bar = 185) - (Area corresponding to Z = 1 or x-bar = 181)

Area corresponding to Z = 1.273 = 0.898

Area corresponding to Z = 0.254 = 0.598

The shaded Area ABCD = 0.898-0.598 = 0.300

Therefore the probability that the sample mean will lie between 181 and 185 is 0.300.

The area of a circle as a function of its diameter is A(d) =  \(\frac{\pi d^2}{4}\).

We have to find the area of a circle as a function of its diameter.

Let the diameter of the circle be d.

We know the formula,

Area of circle = \(\pi r^2\)

Where,

r is the radius of the circle.

\(\pi\)  = constant.

We know that,

Radius is equal to half the diameter of a circle.

Hence, we can write

r = d/2

Where d is the diameter of the circle.

Hence, we can write,

Area of circle as a function of its diameter = A(d) = \(\pi (\frac{d}{2})^2 = \frac{\pi d^2}{4}\).

a) This hypothesis test is that there is sufficient evidence, at a significance level of 0.01, to suggest that coyotes in the specified region tend to live longer than the average age of 1.75 years.

The level of significance in this hypothesis test is α = 0.1. The null hypothesis (H0) is that the population mean age of coyotes in the region is 1.75 years, while the alternative hypothesis (H1) is that the population mean age is less than 1.75 years.

The sampling distribution to be used in this case is the Student's t-distribution, since the sample size is relatively small (n = 51) and the population standard deviation (σ) is unknown.

The value of the sample test statistic can be calculated by using the formula: t = (x - μ) / (s / √n), where x is the sample mean, μ is the population mean, s is the sample standard deviation, and n is the sample size. The calculated value of the test statistic can then be compared to the critical value(s) from the t-distribution to find the p-value. The p-value represents the probability of observing a test statistic as extreme as the calculated value, assuming that the null hypothesis is true.

Based on the calculated p-value and the chosen level of significance, we can determine whether to reject or fail to reject the null hypothesis. If the p-value is less than α, we reject the null hypothesis and conclude that the data are statistically significant. In this case, the statement "At the α = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant" indicates that the data provide evidence to support the claim that coyotes in the specified region tend to live longer than 1.75 years.

Answer:

To multiply the mixed numbers 1 3/4 and 2 1/2, you can convert them to improper fractions, then multiply the numerators and denominators. Here's the step-by-step process:

1 3/4 = (4 * 1 + 3) / 4 = 7/4

2 1/2 = (2 * 2 + 1) / 2 = 5/2

Now, multiply the numerators and denominators:

(7/4) * (5/2) = (7 * 5) / (4 * 2) = 35/8

Therefore, 1 3/4 multiplied by 2 1/2 is equal to the simplified fraction 35/8.

The number of kilograms of pumpkins that were not spoiled is 4 1/10 kg.

To determine the weight of the pumpkins that were not spoiled, we can subtract the weight of the spoiled pumpkins from the total weight. Therefore, the equation to find the weight of the non-spoiled pumpkins would be:

To find the number of kilograms of pumpkins that were not spoiled, we subtract the weight of the spoiled pumpkins from the total weight of the pumpkins.

Given that Samira picked 6 7/10 kg of pumpkins and 2 6/10 kg of pumpkins were spoiled, we can represent the weight of pumpkins that were not spoiled as x kg.

The equation representing this situation is:

6 7/10 kg - 2 6/10 kg = x kg

To simplify the equation, it can convert the mixed numbers to improper fractions:

67/10 kg - 26/10 kg = x kg

Subtracting the fractions, we get:

41/10 kg = x kg

Therefore, the number of kilograms of pumpkins that were not spoiled is 4 1/10 kg.

The required positive numbers are 14.43, 14.43.

According to the statement

we have given that The product of two positive numbers is 208 and the sum is a minimum.

And we have to find these numbers.

So, For this purpose,

Let two positive numbers xy = 208

According to question xy = 208

And then

y = 208/x

and

sum of two positive numbers z=x+y

s= x+ 208/x

then

differentiate with respect to x

ds /dx = d/ dx(x+ 208/x)  -(1)

ds /dx = 1 - 208/ x^2

here ds /dx = 0. so,

1 - 208/ x^2 = 0

x^2 - 208= 0

x = 14.43.

And

differentiate the equation (1) again

d^2s /dx^2 = 0 + 416/x^2)  

then

∴ at point x= 14.43,

d^2s /dx^2 = 416/208.22

d^2s /dx^2 = 1.99

which is greater than zero.

∴ value of s minimum at point x = 14.43

so, y = 208/x

y = 208 /14.43

y = 14.43.

So, The required positive numbers are 14.43, 14.43.

The survival time of a 60kg deer without food at -20 degrees Celsius depends on various factors, including its age, sex, and physical condition. However, assuming the deer is healthy and has 5kg of fat, it could potentially survive for around 30 to 50 days without food.

The exact survival time can vary depending on several factors, such as the deer's level of physical activity, environmental conditions, and how much energy it is expending to stay warm in the cold temperature. Additionally, if the deer is able to find sources of water, this can also increase its chances of survival.

It's important to note that this is just an estimate and that the actual survival time may vary. If the deer is injured or sick, its chances of survival may be reduced, and it may not be able to survive as long without food.

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²
