Answer:

4kg

Step-by-step explanation:

Mr Sharma packed 42 kg of tea into one big bag and sox small bags each of the same size

The first step is to calculate the quantity in the big bag

= 3/7 × 42

= 3×6

= 18

The amount left in the remaining bags is

= 42-18

= 24

Therefore the kg of tea in the small bags can be calculated as follows

= 24/6

= 4

Hence there are 4kg of tea in the small bags

Step-by-step explanation:

a rotation of 180 causes the plotted point to be opposite of itself

The points are K(0, 6), L(-8, 0), J(9, 4).

Given that is a coordinate plane with Points K, L, J we need to determine the location of the points,

So,

You require the point's coordinates, which are made up of an x-coordinate (horizontal) and a y-coordinate (vertical), in order to label it on a coordinate plane.

So, Point K is at 6 units upwards from the origin so the point (0, 6) the x-intercept is zero.

Point L is 8 units vertically left side so the point is (-8, 0) here the y-intercept is zero.

Point J is 9 units vertically right side and 4 units upwards so the point is (9, 4).

Hence the points are K(0, 6), L(-8, 0), J(9, 4).

Step-by-step explanation:

To test the hypothesis of mean differences in artificially sweetened drink consumption among BMI groups, assuming a normal distribution, the researcher might use a one-way ANOVA.

The one-way ANOVA compares the means of three or more independent groups and determines if there are statistically significant differences among them. In this case, the BMI groups (normal weight, overweight, and obese) represent the independent groups, and the number of artificially sweetened drinks consumed is the dependent variable. By conducting a one-way ANOVA, the researcher can assess if there are significant differences in mean consumption among the BMI groups and draw conclusions regarding their hypothesis.

The equation of the line is \(\(y = -4x - 1\)\).

To find the equation of a line passing through two points, we can use the point-slope form of a linear equation:

\(\[y - y_1 = m(x - x_1),\]\)

where \(\((x_1, y_1)\)\) are the coordinates of one point on the line, and \(\(m\)\) is the slope of the line.

Given the points \(\((-1,3)\)\), \(\((1,-5)\)\), we can calculate the slope:

\(\[m = \frac{{y_2 - y_1}}{{x_2 - x_1}} = \frac{{(-5) - 3}}{{1 - (-1)}} = \frac{{-8}}{{2}} = -4.\]\)

Using the point-slope form with one of the points, let's use \(\((-1,3)\)\):

\(\[y - 3 = -4(x - (-1)),\]\)

Simplifying:

\(\[y - 3 = -4(x + 1),\]\)

\(\[y = -4x - 1\]\)

Therefore, the equation of the line passing through the points \(\((-1,3)\)\) and \(\((1,-5)\)\) is \(\(y = -4x - 1\)\).

When a cylinder is intersected by a plane parallel to the bases, the resulting cross-section is a circle.

A cylinder is a solid geometric figure which has two parallel, congruent bases.

The bases are connected by a curved surface called a lateral surface. If a plane is made to intersect a cylinder, the resulting cross-section can be circular or elliptical, depending on how the plane intersects the cylinder.

In this case, if the plane intersects the cylinder parallel to the bases, the resulting cross-section is a circle because any section taken parallel to the base of a cylinder is congruent to the base.

This is true for both right cylinders and oblique cylinders.

Answer:

\(x \approx 14.5 \text{ m}\)

Step-by-step explanation:

We can represent the base of the smaller right triangle with the variable y.

Solving for y using the Pythagorean Theorem:

\(6^2 + y^2 = 11^2\)

\(y^2 = 11^2 - 6^2\)

\(y = \sqrt{121-36}\)

\(y = \sqrt{85}\)

Using this y-value, we can solve for x by applying the Pythagorean Theorem to the larger right triangle.

Remember that the total base is length (4 + \(\sqrt{85\)) meters.

\(6^2 + (4 + \sqrt{85})^2 = x^2\)

\(x=\sqrt{137+8\sqrt{85}}\)

Plugging this into a calculator, we get:

\(\boxed{x \approx 14.5}\)

Step-by-step explanation:

15 of 75 estimated raccoons in the area were tagged. So think of this as a ratio, 15:75.

Divide 75 by the 40 racoons that were captured and you get 1.87500. 75 divided by 1.87500 is the 40 raccoons captured. So 15 divided by the same amount is the number of raccoons with tags. Divide 15 by 1.87500 to find the missing value, which is 8.

The leg-to-hypotenuse ratio is 1/√2

The ladder represents the longest length in the triangle.

Step-by-step explanation:

The set up in the question will b a right angled triangle

Length of the ladder will be the hypotenuse

The distance from the base of the wall to the base of the ladder  is the adjacent

Height of the wall will be the opposite

Note that the longest side is always the hypotenuse (length of the ladder)

Given

length of the ladder = 12foot

The distance from the base of the wall to the base of the ladder = 6√2

When plotting a point on a centimeter square grid, it is essential to know the location of the x and y axes. The x-axis is the horizontal axis, while the y-axis is the vertical axis. Both axes meet at the origin point (0, 0). A point on the grid can be identified by its distance from the origin in the horizontal (x) and vertical (y) directions.

Each square on the grid represents one unit. When locating a point on the grid, it is essential to count the squares from the origin point along the x-axis and y-axis. The point is then identified by its coordinates (x, y). For instance, if a point is three units to the right of the origin point and two units up from the origin point, it would be located at (3, 2).

Similarly, points a and b on a centimeter square grid can be plotted by counting the number of units from the origin along the x and y axes. The point a can be located by counting x units to the right of the origin point and y units up from the origin point.

Similarly, the point b can be located by counting x units to the right of the origin and y units up from the origin point. The points a and b can be identified by their coordinates (xa, ya) and (xb, yb), respectively.

In conclusion, when plotting points on a centimeter square grid, it is essential to locate the x and y axes and count the number of squares from the origin point in the horizontal and vertical directions. The points can then be identified by their coordinates (x, y).

Jamie rides a ferris wheel for five minutes. the diameter of the wheel is 10 meters, and its center is 6 meters above the ground. each revolution of the wheel takes 30 seconds. being more than 9 meters above the ground causes jamie to suffer an anxiety attack.Jamie feels uncomfortable for 150 seconds.

To solve this question, we can calculate how long it takes for Jamie to reach the height of 9 meters.

The diameter of the wheel is 10 meters, so the circumference is 2π x 10 = 62.83 meters.

As each revolution of the wheel takes 30 seconds, Jamie would reach the height of 9 meters after

62.83 / 30 = 2.094 revolutions.

Therefore, it would take Jamie 2.094 x 30 = 62.83 seconds to reach the height of 9 meters and feel uncomfortable. Since Jamie rides the ferris wheel for five minutes, that would mean Jamie feels uncomfortable for

5 x 60 = 300 seconds minus

the time it took to reach the height of 9 meters, which is 300 - 62.83 = 150 seconds.

Answer: 2021

Step-by-step explanation:

We conclude that less than 30% of teen girls smoke to stay thin.

Let p be the percentage of teen girls who smoke to stay thin.

So, the Null Hypothesis,(\(H_{0}\)):

p≥ 30%

This means that at least 30% of teen girls smoke to stay thin

Alternate Hypothesis,(\(H_{A}\)) :

p < 30%

This means that less than 30% of teen girls smoke to stay thin.

The test statistics that would be used here

One sample z proportion statistics:

T.S = p' - p/ \(\sqrt{p'(1-p')/n}\) ≈N( 0,1)

Here p'= sample percent of teen girls who smoke to stay thin = 63/ 273 = 0.231

n = number of sample of teen girls = 273

Now putting these values we have:

Test statistics = 0.231 - 0.30/ \(\sqrt{0.231( 1- 0.231)/ 273}\)

                      = -2.705

So we get the value of z-test statistics as - 2.705.

As there is not provided in the question that the level of significance so we assume it to be 5%. Now at a 5% significance level, the z table gives the critical value of -1.645 for left- the tailed test.

As test statistics is less than the critical value of z that is -2.705< -1.645. So we reject our null hypothesis as will fall in reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore we get that less than 30% of teen girls smoke to stay thin.

The function f(x)=e⁴⁻ˣ   is differentiable for all values of x over the interval (-5,5)

A differential equation is an equation that contains one or more functions with its derivatives.

There are a few ways to tell- the easiest would be to graph it out- and ask yourself a few key questions

Function is continuous over the interval. If it is continuous it is probably differentiable

Does the function have any sharp turns in the interval. A sharp turn means it is not differentiable at that point and therefore not differentiable on the entire interval

f(x)=e⁴⁻ˣ is differentiable over (-5, 5)This is because the exponential function is continuous and infinitely differentiable

a. The number of strings containing at least one pair of adjacent characters that are the same is 4^n - 4 * 3^(n-1), where n is the length of the string. b. The probability that a randomly chosen string of length ten over {a, b, c, d} contains at least one pair of adjacent characters that are the same is approximately 0.6836.

a. To count the number of strings of length n over the set {a, b, c, d} that contain at least one pair of adjacent characters that are the same, we can use the principle of inclusion-exclusion.

Let's denote the set of all strings of length n as S and the set of strings without any adjacent characters that are the same as T. The total number of strings in S is given by 4^n since each character in the string can be chosen from the set {a, b, c, d}.

Now, let's count the number of strings without any adjacent characters that are the same, i.e., the size of T. For the first character, we have 4 choices. For the second character, we have 3 choices (any character except the one chosen for the first character). Similarly, for each subsequent character, we have 3 choices.

Therefore, the number of strings without any adjacent characters that are the same, |T|, is given by |T| = 4 * 3^(n-1).

Finally, the number of strings that contain at least one pair of adjacent characters that are the same, |S - T|, can be obtained using the principle of inclusion-exclusion:

|S - T| = |S| - |T| = 4^n - 4 * 3^(n-1).

b. To find the probability that a randomly chosen string of length ten over {a, b, c, d} contains at least one pair of adjacent characters that are the same, we need to divide the number of such strings by the total number of possible strings.

The total number of possible strings of length ten is 4^10 since each character in the string can be chosen from the set {a, b, c, d}.

Therefore, the probability is given by:

Probability = |S - T| / |S| = (4^n - 4 * 3^(n-1)) / 4^n

For n = 10, the probability would be:

Probability = (4^10 - 4 * 3^9) / 4^10 ≈ 0.6836

The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.

How to find the volume of a rectangular prism and pyramid?

The formula for the volume of a rectangular prism is:

Volume = Length * Width * Height

The formula for the volume of a pyramid is:

Volume = (Base Area * Height) / 3

The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.

This is because the volume of a rectangular prism is calculated by multiplying its three dimensions together, whereas the volume of a pyramid is calculated by multiplying the base area by the height and dividing the result by 3.

Hence, the volume of the rectangular prism is greater than the volume of the pyramid with the same height and base. This is because the rectangular prism has additional volume in the form of its width, which the pyramid does not have.
