The intersection between the sphere and the plane is the is diameter.

A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the centre of the sphere, and r is the sphere's radius.

Given that, segment MN has endpoints on a sphere. If segment MN does not pass through the center of the sphere.

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc.

So, the most specific name for segment MN is chord.

Here, segment MN lies on a plane that intersects the center of a sphere.

A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.

Therefore, the intersection between the sphere and the plane is the is diameter.

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.

Since the test statistic is larger than the critical value, we reject the null hypothesis and conclude that there is a statistically significant difference between the weights of the two cheeses at the 5% level of significance.

The solution to the system of equations is (0, -5) or (4, 3).

What is the system of equations?

A system of equations is a set of two or more equations with the same variables. A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously.

To solve the system of equations, we'll substitute the second equation into the first:

x^2 + (2x - 5)^2 = 25

Expanding the square in the second equation:

x^2 + 4x^2 - 20x + 25 = 25

5x^2 - 20x = 0

5x(x - 4) = 0

So x = 0 or x = 4.

For x = 0:

y = 2x - 5 = -5

For x = 4:

y = 2x - 5 = 3

Hence, the solution to the system of equations is (0, -5) or (4, 3).

Answer:

Step-by-step explanation:

The sum of a geometric sequence can be found using the formula

Sn = a₁ (1 - rⁿ⁻¹)/ (1 - r)

where a₁ is the first term, r is the common ratio, and n is the number of terms.

In this case, a₁ = -8, r = -3, and n = 10.

Plugging these values into the formula, we get

Sn = -8 (1 - (-3)⁹⁻¹) / (1 - (-3))

Sn = -8 (1 + 3⁹) / 4

Sn = -8 (1 + 19683) / 4

Sn = -8 × 19684 / 4

Sn = -4920

The values of variables in the kite is - x = 35°, y = 12.5°. The angles measures of the kite are ∠a = 110°, ∠b = 12.5°, ∠c = 5° and ∠d = 110°.

What is a kite?

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equal angles and two pairs of adjacent equal-length sides as a result of its symmetry. Another name for kites is deltoids.

The given angles of the kite are -

∠a = (3x+5)°

∠b = y°

∠c = (2y-20)°

∠d = (4x-30)°

According to the properties of kite -

The two angles are equal where the unequal sides meet.

So, ∠a = ∠d

(3x+5)° = (4x-30)°

3x - 4x = -30 - 5

-x = -35

x = 35°

Substituting to find the value of ∠a -

∠a = (3x+5)°

∠a = [3(35)+5]°

∠a = (105+5)°

∠a = 110°

Substituting to find the value of ∠d -

∠d = (4x-30)°

∠d = [4(35)-30]°

∠d = (140-30)°

∠d = 110°

According to the properties of the kite ∠ADC = 90°.

So, ∠c = 90°/2 as line BD is a bisector.

(2y-20)° = 90°/2

2(2y-20)° = 90°

(4y - 40)° = 90°

4y = 90° - 40°

4y = 50°

y = 12.5°

Substituting to find the value of ∠b -

∠b = y°

∠b = 12.5°

Substituting to find the value of ∠c -

∠c = (2y-20)°

∠c = [2(12.5)-20]°

∠c = (25-20)°

∠c = 5°

Therefore, the value of angles are ∠a = 110°, ∠b = 12.5°, ∠c = 5° and ∠d = 110°.

Therefore , the solution of the given problem of speed comes out to be

he needs to drive at 77.77 mph.

How quickly something is traveling is determined by its speed from a distance. How far an object moves in a certain length of time depends on its speed. Speed is calculated as follows: velocity = range x time. The most used units for expressing speed are meters per second (m/s), kilometers per hour (km/h), and kilometers per second (mph) (mph).

Here,

70 + 50 = 120 miles is indeed the total distance.

You would need 2.4 hours to travel the 120 miles at such an approximate speed of 50 mph.

However, you are already on the road for 1.5 hours, so you must finish the trip in 0.9 hours.

You need to travel at a speed of 77.77 mph to complete the final 70 miles approximately 0.9 hours.

Nikki's speed during the second part of her trip is the same as her speed during the first part of her trip, 54 miles/hour.

Nikki has to travel a total of 351 miles, and she travels the first 216 miles in 4 hours. The second part of her trip is the remainder of the distance she needs to travel, so we can calculate it by subtracting the distance she traveled in the first part from the total distance:

Second part of the trip = 351 miles - 216 miles = 135 miles

It takes Nikki 2.5 hours to travel the second part of her trip. To calculate her speed, we can divide the distance she traveled by the time it took her:

Speed = Distance / Time

Speed for the second part of the trip = 135 miles / 2.5 hours = 54 miles/hour

To compare her speed during the first and second parts of the trip, we can calculate the speed of Nikki during the first part of the trip:

Speed for the first part of the trip = 216 miles / 4 hours = 54 miles/hour

For a set of 16 positive integers to have a mean, median, and mode all equal to 16, the numbers in the set must all be equal to 16. Therefore, the largest possible value of one of the numbers in the set is 16.

The mean, median and mode of a set of numbers are all measures of the "typical" or "central" value of the set.

The mean is the sum of all the numbers divided by the number of elements in the set, the median is the middle value when a set of numbers is arranged in order of magnitude, and the mode is the number that appears most frequently in the set.

In this case, if all the 16 integers in the set are equal to 16, then the mean, median, and mode will all be 16 as well. Since the question states that the median, mode, and mean are all equal to 16, the only way for this to be true is if all the 16 integers in the set are equal to 16.

A task is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is just the input value, we would state that y is a mathematical function

Given that:

f(s) = 2s + 25

s(w) = 25w

The following combination function is used to determine how many flowers will blossom over the course of w weeks: f(w)

f(s) = 2s + 25

Replace s with s(w)

f(s(w)) = 2(s(w)) + 25

Substitute s(w) = 25w

f(s(w)) = 2(25w) + 25

f(s(w)) = 50w + 25

Hence,

f(w) = 50w + 25

Flowers are used as the units of measurement for f(w).

30 weeks of flowers translates to:

A quadratic equation is a polynomial equation of the form ax^2 + bx + c = 0, where a, b, and c are coefficients and x is the variable.

The roots of a quadratic equation are the values of x that make the equation equal to zero.

Given that the roots of the quadratic equation are (3+√5) and (3-√5), we can set the quadratic equation equal to zero and substitute the roots for x:

ax^2 + bx + c = 0

(x - (3+√5))(x - (3-√5)) = 0

(x - 3 - √5)(x - 3 + √5) = 0

(x - 3 - √5)(x - 3 + √5) = (x-3)^2 - (√5)^2 = (x-3)^2 - 5 = 0

x^2 - 6x + 9 - 5 = 0

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes is 0.375, or 37.5%.

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes can be calculated using the Binomial Distribution formula. The formula is P = (nCr) * (p^r) * (1-p)^(n-r), where n is the number of trials, r is the number of successes, and p is the probability of success.

In this case, n = 4 (4 rats), r = 2 (completion time between 6 and 8 minutes), and p = 0.5 (50% chance of success). Therefore, P = (4C2) * (0.5^2) * (1-0.5)^(4-2) = 0.375.
