Suppose if 55 students in the class’s sample say Yes so, there is not sufficient evidence that more than half of the school student recycle.

and Suppose 63 students in the class’s sample say Yes so, there is sufficient evidence that more than half or majority school student recycle.

A.)

According to given data Suppose 55 students in the class’s sample.

n = 100 and x = 55

⇒ p = [tex]\frac{55}{100}[/tex] = 0.55

hence p' = 0.50

so, p > 0.50

Z = [tex]\frac{p-p'}{\sqrt{} \frac{p'(1-p')}{n} }[/tex]

Z = [tex]\frac{0.55-0.50}{\sqrt{} \frac{0.50(1-0.50)}{100} }[/tex]

so, Z = 1

let level of significance α = 0.05

critical Z value at α = 0.05 for one tail test is 1.645

since Z = 1 < z' = 1.645

do not reject at α = 0.05

there is not sufficient evidence that more than half of the school student recycle.

B.)

According to given data Suppose 63 students in the class’s

given data,

X = 63 and n = 100

now P = 63/100 = 0.63

Z = [tex]\frac{0.63-0.50}{\sqrt{} \frac{0.50(1-0.50)}{100} }[/tex] = 2.6

since, Z = 2.6 > Z' = 1.645

The correct Option (B). Succession may be defined as the change in the ecological community of the species with respect to time. Two main types of succession are primary succession and secondary succession.

The living things that accumulate in the succession is from the simple organism to the complex organism. First lichens will evade in the land. After lichens grass then shrubs and finally the trees will cover the area and convert into the forest.

Primary succession occurs in basically dead areas—regions where the soil is incapable of supporting life due to causes such as lava flows, newly created sand dunes, or glacier-left boulders.

Pioneer microorganisms, plants (lichens and mosses), grassy stage, smaller shrubs, and trees are all stages of primary succession. When there is food available, animals begin to return. The climax community stage is reached when the ecosystem is fully functional.

What is volumes of Solids?

We shall encounter several solids and their corresponding volumes when discussing the concept of the volume of a combination of solids. As is common knowledge, the surface areas and volumes of all three-dimensional shapes depend on their dimensions. As we can see in reality, numerous shapes are created by fusing a variety of shapes. For instance, the combination of cone and cylinder shapes creates a tent. Similar to how a cone and a hemisphere combine to form an ice cream cone. As a result, the volume of the solids combined will equal the total of volume of the individual solids.

Given, region y = 2x²

Volume will be V = π/2 ∫(r²) dr

So we have 1/3 π * r² * h

So V = 4π (1/5)

V =  4π/5unit³

Hence, the volume of the solid is 4π/5unit³

From the given figure, we can conclude the following data:

AP = √3/2(a)  → 1 length of the median for the triangle of side a.

by putting the value of a. we get:

AP = √3/2(2)  = √3

AQ = AP + PQ = √3 + 2

Area of triangle AEΔ = 1/2 × EΔ × AQ = 1/2(2) (√3+2)

AE = AD = √(EQ)² + (AQ)²

When a biased coin is tossed ten times, the likelihood of getting at least nine heads is 0.0463.

The binomial distribution's PMF is;

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

Following are the results of a calculation using a binomial distribution to determine the likelihood of receiving at least 9 heads.

P(X ≥ 9) = P(X = 9) + P(X = 10)

P(X ≥ 9) = ¹⁰C₉. (0.6)⁹ (1 - 0.6)¹ + ¹⁰C₁₀. (0.6)¹⁰ (1 - 0.6)⁹

P(X ≥ 9) = 0.0403 + 0.0060

P(X ≥ 9) = 0.0463

98 % confidence interval for the proportion of all adults in the United States who exercise on a regular basis is 0.440 < P < 0.619.

What does a statistical random sampling entail?

P = x/n

= 89/168

= 0.53

α= 0.02

∴ Zc = Zi - α/2

= 2.326

Now, C.I = P ± Zc * √[P(1-P)/n]

= 0.5 ± 2.326 *√[(0.53(1-0.53)) / 168

Observed proportions (relative frequencies) from a sample are statistics that can be used to estimate probabilities.

a) Thre is 99.73% proportion of observations is in between 190 and 310 .

b)there is 95.44% proportion of observations is in between 210 and 290 .

We have given that,

Mean of population, μ = 250

standard deviations, σ = 20

we have to calculate proportion of observations in the given interval pair.

a) pair of values are 190 and 310

Using Z-score formula,

Z =( x - μ) /σ

=> Z = (190 - 250) / 20 = -3

Similarly, Z = (310 - 250)/20 = 3

So, -3 < z < 3 and from Z score we found p-value

P(190<X<310) = P( 190-u/sd < X-u/sd < 310-u/sd)

= P( X< 310 ) - P(X<190) = P(Z < 3) - P( Z< -3 )

=0.99865 - 0.00135 0.9973 = 99.73%

b) pair is 210 and 290

Z-Score = (210-250)/20 = -2

Z-score = (290-250)/20 = 2

so, -2 < z < 2

From Z score we found p-value

P(210<X<290) = P(X<290) - P(X<210)

= P(Z< 2) - P(Z< -2)

= 0.9772 - 0.0228 = 0.9544 = 95.44%

So, the required proportion are 99.73% and 95.44% proportion of observations in each given pair.

Using triple integrals we know that the solid in question has a volume of 1024/3³ units.

Multiple integrals in mathematics is a definite integrals of a function with many real variables, such as for f.

The area of a region enclosed by the function's curve is calculated using the double integral.

It can also be used to figure out how much space is beneath the surface.

The double integral can also be used to calculate the average value of a function with two variables over the rectangular region.

So, the volume of the solid (V) in this problem must be calculated using the triple integral formula in rectangular coordinates:

[tex]V=\iiint d y d x d z[/tex] ...(1)

The following intervals impose restrictions on the solid:

[tex]y \in\left[x^2, 16\right], x \in[-4,4], z \in[0,4][/tex]

The triple integral is currently explained as follows:

[tex]$$V=\int_0^4 \int_{-4}^4 \int_{x^2}^{16} d y d x d z$$\\[/tex]

Now we integrate three times to get the volume:

[tex]\\\begin{aligned}& V=\int_0^4 \int_{-4}^4\left(16-x^2\right) d x d z \\& V=\left.\int_0^4\left(16 \cdot x-\frac{x^3}{3}\right)\right|_{-4} ^4 d z \\& V=\frac{256}{3} \int_0^4 d z=\frac{1024}{3}\end{aligned}$$[/tex]

The number of seats in the theater is 1510.

Here we have to find the number of seats in the theater.

Data given:

Total row = 20

number of seats on the first row = 28

number of seats on the second row = 33

number of seats on the third row = 38

Therefore we get the series as 28, 33, 38......., which is in arithmetic sequence.

The common difference (d) = 5

Here we have to find the sum of the series.

The formula for the sum of n term of the arithmetic sequence:

[tex]S_{n}[/tex] = n/2( 2a + (n-1)d)

    = 20/2 ( 2× 28 + (20 -1) 5)

The height of the antenna found using trigonometric ratios is about 8 meters

Trigonometric ratios indicates the ratio of the sides of a right triangle, and have values based on the lengths of the sides of a right triangle, drawn on the coordinate plane.

The distance from the building at which Brooklyn stands = 23 meters

Angle of elevation from her eyes to the roof, θ = 24°

Angle of elevation from her eyes to the top of the antenna = 38°

Height of her eyes from the ground = 1.66 meters

[tex]tan(\theta) = \dfrac{Opposite}{Adjacent} = \dfrac{Height}{Horizontal \, distance}[/tex]

Therefore;

Height = Horizontal distance × tan(θ)

Height to the top of the roof, H₁ = Horizontal distance × tan(θ)

Therefore;

H₁ = 23 × tan(24°) ≈ 10.24

Height to the top of the antenna, H₂ = 23 × tan(38°) ≈ 17.97

It is true that the variance is the simplest measure of dispersion and is computed as the difference between the maximum value and the minimum value in the data set.

Variance is a measure of dispersion that, in contrast to range and interquartile range, accounts for the spread of all data points in a data collection. Along with the standard deviation, which is just the square root of the variance, it is the measure of dispersion that is most frequently employed. The statistical assessment of the variation in numbers within a data collection is known as variance.

Average increase refers to the average rate of growth that a variable experiences within a given period.

According to the given question:

The number of pollinated flowers as a function of time in days is represented by the function f(x) = [tex]3^{(x/2)[/tex]

To find the average increase in the number of flowers pollinated per day between days 4 and 10, we use the formula

{f(10) - f(4)}/{10 - 4}

Now f(10) = [tex]3^{(10/2)[/tex]

               = 243

Also f(4) = [tex]3^{(4/2)[/tex]

             = 9

Therefore average increase = {f(10) - f(4)}/{10 - 4}

                                               = (243 - 10)/10 - 4

                                               = 234/6
