The sequence is decreasing as n increases and sequence converges to the value 0.

The given sequence is defined as aₙ = 1 / (7n + 3).

To determine if the sequence converges or diverges, we need to analyze its behavior as n approaches infinity.

As n increases, the denominator 7n + 3 also increases which means that the values of aₙ will get smaller and smaller, approaching zero as n becomes larger.

The sequence converges to the value 0.

y=mx+b

m= slope and b= y intercept

you'll start with a point on the y axis on -1

and the slope will go up so towards the right corner up but 2/1 points

The histogram on the x-axis represents the data and on the y-axis represents the frequency:

a. Approximately Bell-Shaped

We have the next data set:

4; 5; 6; 6; 6; 7; 7; 7; 7; 7; 7; 8; 8; 8; 9; 10

The mode is 7 because is the value most repeated

The mean is 7 because:

The median is 7.

Hence, we have the next histogram approximately Bell-Shaped:

4 - frequency of 1

5-frequency of 1

6- frequency of 3

7- frequency of 6

8 -frequency of 3

9 -frequency of 1

10- frequency of 1

Then:

b. Skewed Left

We have the next data set:

4566677778

This histogram is not symmetrical. Then, the mode, the median, and the mean are different.

c. Skewed Right

We have the next data set:

6;7;7;7;7;8;8;8;9;10

d.Uniform

We have the next data set

4,4,4,4,5,5,5,5,6,6,6,6,7,7,7,7,8,8,8

It is uniform because some of the values have the same frequency or near value to each other.

Step-by-step explanation:

Answer:

x + 3y = -15

Step-by-step explanation:

There are 2 ways to find this equation:

The first way:  We have: y = ax + b (this is the line, right?)

The line is through the point (-6, -3) so we have:

-3 = (-6)a + b      (1)

The line is also through the point (-9, -2) so we have:

-2 = (-9)a + b.       (2)

From (1) and (2) we get a equals -1/3, b equals -5. Then:

\(y=-\frac{1}{3} x - 5\)

<=> \(x + 3y=-15\)

The second way:

Let A(-6, -3) and B(-9, -2), then AB = (-3, 1).

=> The normal vector of this line is n = (1, 3).

The line that is through the points A(-6, -3) and B(-9, -2), and has the normal vector n=(1, 3) has the equation:

\(1(x+6) +3(y+3)=0\\x+3y +15=0\\x+3y=-15\)

Answer:

82.6666666667 or just 82.67

Step-by-step explanation:

The value of 248 ÷ 3 equals 82.

To divide 248 by 3, we set up the division equation: 248 ÷ 3.

Starting with the first digit of 248, which is 2, we check how many times 3 can be divided evenly into 2. Since 3 is larger than 2, we move on to the next digit, 24.

Now, we divide 24 by 3, which gives us 8.

Next, we bring down the next digit, 8, making the current dividend 88.

We divide 88 by 3, resulting in a quotient of 29.

Since there are no more digits to bring down, the division is complete.

Therefore, 248 ÷ 3 equals 82.

\(\dfrac{dh}{dt}=-2.1\text{ in/s}\)

To find:

The rate of change in volume at \(r=120\text{ in. and }175\text{ in.}\)

Solution:

We know that, volume of a cone is

\(V=\dfrac{1}{3}\pi r^2h\)

Differentiate with respect to t.

\(\dfrac{dV}{dt}=\dfrac{1}{3}\pi\times \left[(r^2\dfrac{dh}{dt}) + h(2r\dfrac{dr}{dt})\right]\)

Substitute the given values.

\(\dfrac{dV}{dt}=\dfrac{1}{3}\times \dfrac{22}{7}\times \left[(120)^2(-2.1) +175(2)(120)(1.4)\right]\)

\(\dfrac{dV}{dt}=\dfrac{22}{21}\times \left[-30240+58800\right]\)

\(\dfrac{dV}{dt}=\dfrac{22}{21}\times 28560\)

\(\dfrac{dV}{dt}=29920\)

Step-by-step explanation:

I don't know a formula for this but I can see that <CRE is a 90° angle so 7f+2f=90 and if f=10 7f=70 and 2f=20 which fits

The measure of angle of each is 70° and 20°.

Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.

Angles are usually measured in degrees or radians.

The given angles are complementary.

That is, ∠CRE is complementary, which means the angle is 90 degrees.

∠CRT + ∠TRE = 90°

(7f)° + (2f)° = 90°

9f = 90°

f = 90 / 9

f = 10

Hence ∠CRT = (7f)° = 70°

∠TRE = (2f)° = 20°

Hence the measure of each of the angle is 70° and 20°.

the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins,

how to solve probability

If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.

To find the best prediction for the number of times the spinner will land on yellow if it is spun 72 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.

In this case, the expected value of the number of times the spinner will land on yellow in 72 spins is simply the probability of landing on yellow multiplied by the number of spins:

Expected value = Probability of yellow x Number of spins

Expected value = (1/6) x 72

Expected value = 12

Therefore, the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins, we can expect the spinner to land on yellow approximately 12 times on average. However, it's important to remember that this is just a prediction based on probability, and the actual number of yellow spins may vary.
