Answer:

Candelas - 154cm

Dianas - 162 cm

Step-by-step explanation:

Median is the mean of the two middle numbers when the numbers are arranged in an ascending order.

We will first have to workout the order when they are placed in ascending order.

Note: Everything here is in ascending order.

Albertos cannot be the shortest as if that happened, the median will not be 160 (Dianas will have to be 179cm as the given range is 21 cm and the mean of Candelas and Bill can never be 160 cm.)

Albertos will have to be second as it cannot be third.( The median will not be 160 when the third number is greater than the second number.)

Now, Dianas will have to be third. ( It can't be first, nor it can be fourth as the median of the height will not be possible to be 160 again without changing the order.)

So, next, obviously, Candelas is first.

So, the order is,

Candelas, Albertos, Dianas, Bill

or,

Candelas , 158, Dianas, 175cm.

Dianas is 162 cm if the mean of 158 cm and Dianas's height is 160 cm.

Candelas's height is 175 - 21 = 154 cm

So the height of Candelas is 154 and height of Dianas is 162.

With a speed of 0.419 m/s, the rider fast is a rider rising when his seat is 16m above ground level

The formula for tangential velocity is 2*pi*r/T --> 2*pi*10/120 --> pi/6.

It is 6 meters above the center of the wheel while the rider is 16 meters above the ground.

The horizontal portion of this distance must be 8 meters as its separation from the wheel's center is 10 meters (depending on the radius).

This indicates that the velocity and seat both make angles of 36.87 degrees off vertical and arctan(6/8) over the origin, respectively.

We will take into account the vertical component of the tangential velocity since the rate at which the seat is rising is what we're interested in.

Pi/6 * cos(arctan(6/8)) yields a value of 0.419 m/s.

80 grow into plants

Step-by-step explanation:

Fraction word problems:

   Out of 13 seeds, 8 grew into plants.

[tex]\sf \text{Number of seeds grown out of 130 okra seeds} = \dfrac{8}{13}*130[/tex]

                                                                       = 8 * 10

                                                                       = 80

Out of 130 seeds, 80 grow into plants.

For Palanzios' Pizzeria and Guido’s Pizza to cost the same, the number of toppings needed is 2.

Let's begin by assigning a letter to represent our unknown:

   x = Number of toppings to be added to each pizza

Now,

Based on the Given information :

Expressions for the cost of each pizza with its toppings:

   Palanxio's Pizza:  6.80 + 0.90x

   Guido's Pizza:      7.30 + 0.65x

Now,

Equating the costs of both pizzas and solve for our unknown (x):

   ⇒ 6.80 + 0.90x = 7.30 + 0.65x

  ⇒ 0.90x - 0.65x = 7.30 - 6.80

   ⇒ 0.25x = 0.50

   ⇒ x = 0.50/0.25

   ⇒ x = 2

Therefore, There are 02 toppings to be added to each pizza.

Finally, we can verify our answer by putting the values back into our equation :

   6.80 + 0.90x = 7.30 + 0.65x    

   6.80 + 0.90(2) = 7.30 + 0.65(2)

   6.80 + 1.80 = 7.30 + 1.30

Applying proportion, the money her mother donated is: $64.

Proportion is a mathematical concept that describes the relationship between two or more values that are expressed as a ratio. It is used to compare the size of one value to another.

A proportion can be written in the form of an equation, such as a/b = c/d, where a, b, c, and d are values, and a and b are the values being compared to c and d.

We can use the proportion of the pledge to the distance biked to find the amount of money Emily's mother will donate.

The proportion of the pledge to the distance biked is 0.40/$ for every 0.75 mile.

So for 24 miles, the amount of money pledged would be:

0.40/0.75 * 24 = $64

The probability of getting at least 6 oranges in a bag of 10 fruits is the sum of probability of getting 6 oranges, probability of getting 7 oranges, probability of getting 8 oranges, probability of getting 9 oranges and probability of getting 10 oranges.

We can use the binomial probability formula to calculate the probability of getting at least 6 oranges in a bag of 10 fruits, which is:

P(X >= 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

Where X is the number of oranges in the bag, and the probability of getting an orange is p and the probability of getting an apple is (1-p)

Now, since we don't know the proportion of oranges to apples in the bin, we can't find p. However, we can use the cumulative binomial distribution function to find the probability of getting 6 or more oranges in a bag of 10 fruits.

The cumulative binomial distribution function is the probability of getting r or less successes in n trials, where a success is getting an orange and a failure is getting an apple.

So

The central angle of the arc in degrees is 162 degrees.

The circumference of the circle is 10 units. The length of the arc is 9 / 2 units. The central angle can be calculated as follows;

We can find the central angle by comparing it to the length of the arc.

Therefore, we know the circle has a circumference of 10. We also know a circle is 360°.  The length of the arc is given as 9 / 2 units(4.5 units).

To determine the degrees of the central angle, we have to set up a ratio and set the unknown angle as x.

Hence,

length of the arc / circumference = angle of the arc / angle of the circle

4.5 / 10 = x / 360

cross multiply

360 × 4.5 = 10x

1620 = 10x

divide both sides by 10

x = 1620 / 10

x = 162 degrees

The solutions of the quadratic equation are given by x = (29 ± √825) / 4 which are two complex numbers.

What is a quadratic equation?

A quadratic equation is a type of polynomial equation that has the form of ax^2 + bx + c = 0, where x is the variable, and a, b, and c are coefficients. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b and c are constants. The solutions of a quadratic equation are given by the quadratic formula: x = (-b ± √(b^2-4ac)) / 2a

To solve for x in the equation 2x^2 -19x + 2 = -10x, we need to rearrange it in the standard form of a quadratic equation by isolating the x^2 term and moving the other terms to the other side:

2x^2 -10x -19x +2 = 0

2x^2 -29x +2 = 0

Now we can apply the quadratic formula:

x = (-b ± √(b^2-4ac)) / 2a

x = (-(-29) ± √((-29)^2-422)) / 2*2

x = (29 ± √(841-16)) / 4

x = (29 ± √(825)) / 4

Answer:

To solve this problem, we need to use the formula for the volume of a cylinder: V = πr^2h, where V is the volume, r is the radius, and h is the height.

Step 1: We know that the radius of the tank is 2 feet and that it is being filled at a rate of 4 cubic feet per minute. We also know that the tank is half full, so we can assume that the height of the water in the tank is half the height of the tank itself.

Step 2: We can use the volume formula to find the volume of the tank when it is half full.

V = πr^2h

V = π(2^2)(h/2)

V = 4πh/2

Step 3: We can divide the rate of fill by the volume of the tank when it is half full to find the rate of change of the height of the water.

dh/dt = 4/(4π/2)

dh/dt = 2/π ft/min

Final Answer: The level of the water in the tank is rising at a rate of 2/π feet per minute when the tank is half full.

Explanation:

Let z be adjacent to angle y, and angle z is inside the triangle on the right.

Adding up the inside angles of any triangle always gets us to 180 degrees.

We'll use this fact to find z.

z+30+50 = 180

z+80 = 180

z = 180-80

z = 100

Angle y and angle z are supplementary angles. They form a straight line of 180 degrees.

So,

y+z = 180

y+100 = 180

y = 180-100

y = 80

--------------

We can follow the same steps as in the previous section to determine that angle x is 110 degrees.

A shortcut is to use the Remote Interior Angle Theorem.

This theorem says that adding two interior angles will get us the exterior angle that isn't adjacent to either interior angle mentioned.

Notice for instance that angle x is not adjacent to the bottom-left 30 degree angle nor is it adjacent to angle y.

Furthermore, you could use the Remote Interior Angle Theorem to determine the measure of angle y. Note how y = 30+50 = 80. This time the "30" we focus on here is inside the triangle on the right.

Since the square roots contain two different terms, we cannot simplify them any further. However, we can remove any perfect squares that are contained inside the square roots. To do this we can factor out the perfect squares from the terms inside the square roots.

For the first square root, 72x323 = 72 x 9 x 37. Since 72 and 9 are both perfect squares, we can factor out these terms to get 72√37x323.

In a trapezium, the sum of the outer angles is always equal to 360 degrees because, in any convex quadrilateral, the sum of the four angles is consistently 360 degrees. As a trapezium is a type of convex quadrilateral, the sum of its four angles is 360 degrees, regardless of its shape or size.

We can simplify this equation by combining like terms on one side and isolating the variable on the other.

First, combine like terms: x + 5 + 3x - 8 + 5x + 10 + x + 10 = 360

(x + x) + (5 + 10 + 10) + (3x + 5x) = 360

10x + 17 = 360

Then, subtract 17 from both sides to isolate the variable on one side:

10x = 343

Finally, divide both sides by 10 to solve for x:

x = 34.3

So the solution to the equation is x = 34.3

There is a statistically significant difference between the weights of the two cheeses at the 5% level of significance.

Standard deviation is a measure of how spread out a set of numbers is from the mean. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. In other words, it is a measure of how much the values in a dataset differ from the mean, or average, value. Standard deviation is a useful tool for understanding the distribution of data and can be used to identify outliers and compare data sets.

To answer this question, we must use a two-tailed hypothesis test, where the null hypothesis is that there is no difference between the two cheeses. The alternative hypothesis is that there is a significant difference between the two cheeses.

Using the sample data provided, we are able to calculate the test statistic, which in this case is 2.02. This can be compared to the critical value from the t-distribution table, which is 1.711 for a 5% level of significance and 31 degrees of freedom.
