The total number of people at the Stadium = 4250

What is Total Number?

When you add up or count up all of something's components, you obtain the entire number or cost of that thing.

Let the total number of people at the stadium be x.

It is given that 4% of people were teenagers.

So, (4x / 100) were teenagers

Then according to our question we have,

4x / 100 = 170

x= (170 × 100) / 4

x= 17000/4

x= 4250

The total number of people at the Stadium = 4250

90 mm Hg is Zigg's mean arterial pressure.

Here's the formula for calculating MAP: MAP = (CO x SVR) + CVPR

where:

CO stands for cardiac output (measured in liters per minute).

SVR stands for systemic vascular resistance (measured in mm Hg/L/min).

CVPR stands for central venous pressure (measured in mm Hg).

Now, let's get started with the calculation of MAP.

First, let's calculate CO (cardiac output): CO = HR x SV

where:

HR is heart rate (measured in beats per minute).

SV is stroke volume (measured in milliliters per beat).

CO = 140 bpm x 95 mlCO = 13300 ml/minCO = 13.3 L/min

Next, we need to calculate SVR (systemic vascular resistance).

The formula for calculating SVR is: SVR = (MAP - CVP) / CO

where:

MAP is mean arterial pressure (measured in mm Hg).

CVP is central venous pressure (measured in mm Hg).

CO is cardiac output (measured in liters per minute).

Since we don't have CVP in this question, let's assume it to be zero.

SVR = (MAP - 0) / 13.3 L/minSVR = MAP / 13.3 L/min

Now, we can rearrange the above equation to calculate

MAP:

MAP = SVR x 13.3 L/minMAP = 60 mm Hg (diastolic pressure) + 1/3 (systolic pressure - diastolic pressure)MAP = 60 mm Hg + 1/3 (150 mm Hg - 60 mm Hg)MAP = 60 mm Hg + 30 mm HgMAP = 90 mm Hg

Therefore, Ziggy's mean arterial pressure (MAP) is 90 mm Hg.

The weight of the eggs in grams 95.38 grams.

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X ~ N(58,21)

where µ = 58 and σ = 21

The z score for this case is given by this formula:

z = x -  µ/σ

We know that the value of z = 1.78 and we want to estimate the value of X. If we solve for X from the z formula we got:

X =  µ+1.78σ

= 58 + 1.78×21

= 95.38

So, the corresponding weight for a z score of 1.78 is 95.38 grams.

An acute triangle is made up of three acute angles. An obtuse triangle is formed by one acute angle and two obtuse angles.

Three sides and three vertices make up a triangle, which is a polygon. It is among the fundamental forms in geometry. Triangle ABC is a graphical representation of a triangle having vertices A, B, and C. In Euclidean geometry, any three points identify a distinct triangle and, concurrently, a distinct plane if they are not collinear.

Three acute angles make up an acute triangle. One obtuse angle and two acute angles make form an obtuse triangle. Because in Euclidean geometry all angles in a triangle must be 180 degrees, a triangle cannot contain more than one obtuse angle.

Answer:

The difference between the principal and the compound interest in three years is Rs 17,994

Step-by-step explanation:

The compound interest is given according to the following formula;

\(C.I. = P \cdot \left ( 1 + \dfrac{r}{n} \right ) ^{n\cdot t} - P\)

The given amount of the compound after 2 years = Rs 5,460

The given amount of the compound after 4 years = Rs 12,066.60

Therefore, we have;

\(5,460 = P \cdot \left ( 1 + \dfrac{r}{100} \right ) ^{2} - P\)...(1)

\(12,066.60 = P \cdot \left ( 1 + \dfrac{r}{100} \right ) ^{4} - P\) ...(2)

Dividing equation (2) by (1), we have;

\(\dfrac{12,066.60}{5,460} = \dfrac{P \cdot \left ( \left ( 1 + \dfrac{r}{100} \right ) ^{4} - 1\right )}{P \cdot \left (\left ( 1 + \dfrac{r}{100} \right ) ^{2} -1 \right ) } =\dfrac{\left ( 1 + \dfrac{r}{100} \right ) ^{4} - 1}{\left ( 1 + \dfrac{r}{100} \right ) ^{2} -1 }\)

\(Let \ \left ( 1 + \dfrac{r}{100} \right ) ^{2} = x, we \ get;\)

\(\dfrac{12,066.60}{5,460} =\dfrac{\left ( 1 + \dfrac{r}{100} \right ) ^{4} - 1}{\left ( 1 + \dfrac{r}{100} \right ) ^{2} -1 } = \dfrac{x^2 - 1}{x - 1}\)

∴ 12,066.60 × (x - 1) = 5,460 × (x² - 1) = 5,460 × (x - 1) ×(x + 1)

∴ 12,066.60 × (x - 1)/(x - 1) = 5,460 × (x + 1)

12,066.60/5,460 = x + 1

x =  12,066.60/5,460 - 1 = 1.21 = 121/100

x = 121/100

\(\left ( 1 + \dfrac{r}{100} \right ) ^{2} = x = \dfrac{121}{100}\)

\(1 + \dfrac{r}{100} =\sqrt{ \dfrac{121}{100}} = \dfrac{11}{10}\)

We get

\(\dfrac{12,066.60}{5,460} =\dfrac{221}{100}\)

\(\therefore \dfrac{12,066.60}{5,460} =\dfrac{221}{100} = \left ( 1 + \dfrac{r}{100} \right ) ^{2}\)

\(1 + \dfrac{r}{100} = \sqrt{ \dfrac{221}{100} } = \dfrac{\sqrt{221} }{10}\)

\(\dfrac{r}{100} = \dfrac{\sqrt{221} }{10} - 1\)

\(\dfrac{r}{100} = \dfrac{11}{10} - 1 = \dfrac{1}{10} = 0.1\)

r = 100 × 0.1 = 10%

r = 10%

Therefore, we have;

\(5,460 = P \cdot \left ( 1 + \dfrac{r}{100} \right ) ^{2} - P = P \times \left ( 1 + 0.1\right ) ^{2} - P\)

\(5,460 = P \times \left ( 1 + 0.1\right ) ^{2} - P = P \times \left (\left ( 1 + 0.1\right ) ^{2} - 1\right) = P \times \dfrac{21}{100}\)

\(P = \dfrac{100}{21} \times 5,460 = 26,000\)

The principal = Rs. 26,000

The compound interest in 3 years is therefore;

\(CI_3 = 26,000 \times \left ( 1 + \dfrac{10}{100} \right ) ^{3} - 26,000= 8606\)

The difference, 'd', between the principal and the compound interest in three years, is given as follows;

d = P - CI₃

d = 26,600 - 8606 = 17994

The difference between the principal and the compound interest in three years, d = Rs 17,994.

Suppose u(x,0) = sin(πx) + ∑ \(5/n^{10}\) sin(2nπx). n=1 If u(x, t) represents the temperature of a rod at a position x and time t, then at time t the midpoint has the temperature U(1/2, t) = 2.718.

The solution to the given heat equation with the given initial and boundary conditions is:

u(x,t) = ∑ (2/nπ) sin(nπx) e^(-n^2π^2t/16), n=1 [infinity]

Using this solution, we can find the temperature at the midpoint x=1/2:

U(1/2, t) = ∑ (2/nπ) sin(nπ/2) e^(-n^2π^2t/16), n=1 [infinity]

Plugging in t=0, we get:

U(1/2, 0) = ∑ (2/nπ) sin(nπ/2), n=1 [infinity]

Using the identity sin(nπ/2) = 1 if n is odd, and 0 if n is even, we can simplify this expression:

U(1/2, 0) = ∑ (2/(2n-1)π), n=1 [infinity]

This is a divergent series, so we cannot find its exact value. However, we can approximate it by truncating the series at a large enough value of N:

U(1/2, 0) ≈ ∑ (2/(2n-1)π), n=1 to N

For example, if we take N=10, we get:

U(1/2, 0) ≈ 3.8197

Therefore, at time t, the midpoint of the rod has the temperature U(1/2, t) ≈ ∑ (2/nπ) sin(nπ/2) e^(-n^2π^2t/16), n=1 to N, which depends on the value of t and the number of terms included in the series approximation.
At time t, the midpoint of the rod has the temperature:

U(1/2, t) = sin(π(1/2)) * e^(-16(π^2)t) + ∑ [5/n^10 * sin(2nπ(1/2)) * e^(-16(2nπ)^2t)]. n=1 to ∞

Here, e represents the base of the natural logarithm (approximately 2.718).

Using the box-whisker plot approach, it is computed that 50% of the data values are more than 45.

In a box-whisker plot, as seen in the illustration, The minimum, first quartile, median, third quartile, and maximum quartiles are shown by a rectangular box with two lines and a vertical mark. In descriptive statistics, it is employed.

Given the foregoing, the box-whisker plot depicts a specific collection of data. A vertical line next to the number 45 shows that it is the 50th percentile in this instance and that 45 is the median of the data.

It indicates that 50% of the values are higher than 45 and 50% of the values are higher than 45.

Using this technique, we can easily determine the proportion of data for which the value is higher or lower. Data analysis and result interpretation are aided by it. Therefore, 50% of values exceed 45.

A 10-year-old youngster is having his physical evaluated by the nurse right now. The nurse records that the child weighed 80 pounds during the previous year's checkup. The child's current weight should be around 86 pounds based on growth typical for this age group.

As per the data given in the above question are as bellow,

According to average growth for a 10-year-old boy,

the expected weight gain per year is around 5 to 7 pounds.

Assuming a steady growth rate,

the expected current weight of the child would be:

=80 pounds (last year's weight) + 6 pounds (average weight gain for a 10-year-old boy)

= 86 pounds

If the omnibus null hypothesis is rejected in a one-factor ANOVA, then, we can conclude that at least one of the population means is different from at least one other population mean.

ANOVA table gives us the total sum of squares ( TSS ), the residual sum of squares ( RSS ) and the estimated sum of squares ( ESS ).

It establishes the relation that:

ESS + RSS = TSS.

If we reject the omnibus null hypothesis, then it means that:

at least one of the population means is different from at least one other population mean.
