17,242 rounded to the nearest 10,000 is 20,000.

The given number is 17,242.

We need to round the given number to the nearest 10,000.

To round a number to the nearest 10,000, check the thousands of digits to decide whether to round up or round down. If the thousands are 5000 or more, round up. If they are 4999 or less, round down. In the given number the thousands are greater than 5000.

So, 17,242 rounded to the nearest 10,000 is 20,000.

Therefore, 17,242 rounded to the nearest 10,000 is 20,000.

Answer:

\(\large\boxed{49}\)

Step-by-step explanation:

Belivers to skeptics = 15 : 7

From the above ratio, we know that:

Believers = 15

Skeptics = 7

There were 105 believers, then we can rewrite the original ratio to be equal to the new one, to solve for x.

15 : 7 = 105 : x

Ratios can be written as fractions. Rewrite to simplify.

\(\frac{15}{7}\) = \(\frac{105}{x}\)

Cross multiply (numerator * denominator = numerator * denominator)

7 * 105 = 15 *x

735 = 15x

Divide both sides of the equation by 15

x = 49

There were 49 skeptics.

From the question, we can derive the following?

1 1/3 cups of milk to one cup of flour.

We should find the quantity of flour that will be needed if 2 1/3 cups of milk is used.

Let x be the unknown quantity of flour use.

1 1/3 = 4/3

2 1/3 = 7/3

4/3 ---------- 1

7/3 ---------- x

Lets cross multiply:

4/3 * x = 7/3 * 1

4/3x = 7/3

Divide both sides by 4/3

x = 7/3

4/3

x = 7/3 * 3/4

The 3 cancels out:

x = 7/4

x = 1 3/4

Therefore, the quantity of flour needed for a 2 1/3 cups of milk is 1 3/4.

Answer:

Surface Area of the Cylinder is 1156.11

Step-by-step explanation:

To find the Surface Area of a Cylinder, the equation given is  A = 2πrh+2πr2

Given the radius and height of the cylinder, we plug those numbers into the equation to get;

A = 2π(8)(15)+2π(8)2

= 1156.11

Answer:  

1155.52 cm²

Step-by-step explanation:

SA = LSA (Pb x h) + 2B                  

- r = 8 cm, h = 15, π (pi) = 3.14

Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)

8 x 2 = 16 x 15 = 240 x 3.14 = 753.6

Area of the Base x 2 = πr² x 2

8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92

753.6 + 401.92 = 1155.52

Perpendicular lines have slopes that are negative reciprocals of each other.

To find a line that is perpendicular to another line, you need to consider the relationship between their slopes. Perpendicular lines have slopes that are negative reciprocals of each other. Here are the steps to find a line perpendicular to another line:

1. Determine the slope of the given line. If the line is in the form of y = mx + b, where m is the slope, you can directly identify it. Otherwise, rearrange the equation into slope-intercept form.

2. Calculate the negative reciprocal of the slope. To do this, take the reciprocal of the slope (flip the fraction) and change the sign to negative. Let's call this new slope m'.

3. Use the negative reciprocal slope, m', along with a known point on the line to write the equation of the perpendicular line. Let's say the known point is (x₁, y₁).

  - If you already have the slope-intercept form y = mx + b of the given line, you can use the point-slope form of a line: y - y₁ = m'(x - x₁). Substitute the values of m', x₁, and y₁ to write the equation.

  - If you have two points on the given line, (x₁, y₁) and (x₂, y₂), you can use the slope-point form of a line: y - y₁ = m'(x - x₁). Again, substitute the values of m', x₁, and y₁.

4. Simplify and rearrange the equation if necessary. Usually, you'll end up with an equation in slope-intercept form (y = mx + b), point-slope form, or standard form (Ax + By = C) depending on the form you started with.

By following these steps, you can find the equation of a line that is perpendicular to a given line.

What is Congruence of Triangle?

Triangle congruence: Two triangles are said to be congruent if all three of their corresponding sides are equal and all three of their corresponding angles are equal in size. These triangles can be moved, rotated, flipped, and turned to look exactly the same.

Solution:

By SAS rule, two triangles are said to be congruent if any two sides and the angle included between the sides of one triangle are comparable to the corresponding two sides and the angle included between the sides of the second triangle.

In given figure, sides AB= PQ, BC=QR and angle between AB and BC equal to angle between PQ and QR i.e. ∠B = ∠Q. Hence, Δ ABC ≅ Δ PQR.

The radius of the hemisphere is r = 34.6 cm

Given data ,

The volume of a hemisphere can be calculated using the formula:

V = (2/3) π r³

Now , the volume of the hemisphere is V = 86784 cm³

Let the radius be represented as r

86784 = (2/3) x π x (r)³

On solving for r , we get

r³ = ( 86784 x 3 ) / 2π

r³ = 41,436.3077

Taking roots on both sides , we get

r = 34.6 cm

Therefore , the value of r is r = 34.6 cm

Hence , the radius is r = 34.6 cm

Answer:

Step-by-step explanation:

we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50

3 angles in the equilateral triangle are equal to 60

we have 50 + 60 +h =the angle of PQR =180

h=70

Answer: h = 70°

In the triangle with Angle R = 65

It is a isoceles triangle as two sides are equal

So base angles will be equall too

Then the third angle will which is the q one will be

65+65+q = 180

q = 180 - 130

q = 50

In the other triangle with all sides equal will be equilateral triangle which means all angles equal = 60

So

Now ATQ

60 + 50 + h = 180

h = 180 - 110 (Angles on a straight line adds upto 180)

The correct answer is A. Standard deviation measures the dispersion or variability around the expected value or mean of a data set. It is a commonly used statistical measure to quantify the spread of data points.

Standard deviation is calculated by taking the square root of the variance. The variance is the average of the squared differences between each data point and the mean. By squaring the differences, negative values are eliminated, ensuring that the measure of dispersion is always positive.

A higher standard deviation indicates greater variability or dispersion of data points from the mean, while a lower standard deviation suggests that the data points are closer to the mean.

On the other hand, the mean (option B) is a measure of central tendency that represents the average value of a data set. It does not directly measure the dispersion or variability around the mean.

The coefficient of variation (option C) is a relative measure of dispersion that is calculated by dividing the standard deviation by the mean. It is useful for comparing the relative variability between different data sets with different scales or units.

The chi-square test (option D) is a statistical test used to determine if there is a significant association between categorical variables. It is not a measure of dispersion around the expected value.

If each train has 18 carriages and each carriage has 30 seats, then 649 trains would be needed to seat 350,000 passengers.

The total number of seats on each train must first be determined:

18 carriages × 30 seats per carriage = 540 seats per train.

We may divide the total number of passengers by the number of seats per train to get how many trains are required to accommodate 350,000 passengers:

350,000 passengers ÷ 540 seats per train ≈ 648.15

We have to round up to the nearest whole number because we are unable to have a fraction of a train. Thus, 649 trains would be required to accommodate 350,000 passengers.

The polar equation for the curve represented by the cartesian equation x² + y² = 36 is r = 6.

This can be derived by converting the equation to polar coordinates using the substitution x = r cos(θ) and y = r sin(θ), and simplifying the equation to r² = 36, which further simplifies to r = 6 after taking the square root.

Thus, the polar equation is r = 6, indicating that the curve is a circle centered at the origin with a radius of 6.
