Susan would charge $7.50 to babysit 5 kids.

The unitary method is used to calculate the value of a single unit from a given multiple. If the cost of 40 pens is Rs. 400, how do you calculate the value of one pen? The unitary method can be used to accomplish this. Furthermore, once we've determined the value of a single unit, we can multiply that value by the number of units needed.

Given,

Amount charged for 3 kids =$4.50

then,

Amount charged for 1 kid will be [tex]\frac{4.50}{3}=$1.50[/tex]

now, amount charge to babysit 5 kids =1.50*5=$7.50

Thus, Susan would charge $7.50 to babysit five children..

The statistical techniques of analysis of variance (ANOVA) and analysis of covariance (ANCOVA) are used to test the validity of the hypothesis regarding the comparison of group mean values.

The term "parametric approach" refers to a statistical technique used to compare the means of two normally distributed continuous variables.

In contrast to ANOVA, which is used to compare the means among three or more groups, the Student's t test (also known as the T test) is used to compare the means between two groups.An ANOVA test with a significant P value identifies at least one pair in which the mean difference was statistically significant.

The post-hoc test (multiple comparisons) is utilized to determine whether pair(s) are significant. When at least one covariate (continuous variable) in an ANOVA test is altered to eliminate confounding variables from the outcome, the procedure is known as an ANCOVA. Because inferences about means are made by analyzing variance, the ANOVA test (F test) is referred to as "Analysis of Variance" rather than "Analysis of Means."

the volume of the region bounded by y = 2x²  is 4π/5unit³

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

After solving the equation the value obtained for x will be equal to 5.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the given information in the question,

The equation of the line passing through the given coordinates will be,

m = (y2 - y1)/(x2 - x1)

The given points are (7, 1) and (4, 8)

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:

We conclude that there is zero (0) fraction of coal left in the bag with Tom.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole.

A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

The number is represented mathematically as a quotient, where the numerator and denominator are split.

Both are integers in a simple fraction.

A fraction appears in the numerator or denominator of a complex fraction.

The numerator of a proper fraction is less than the denominator.

So, a fraction of coal left in the bag:

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.

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 average increase in the number of flowers pollinated per day between days 4 and 10 is 39.

What is average increase?

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

                                               = 39

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.
