Answer:

The statement "The series converges by the Integral Test" is true. The Integral Test is a method used to determine the convergence or divergence of a series. The test states that if the series is of the form:

∑(f(n))

where f(n) is a positive and continuous function defined for n ≥ 1 and is decreasing for n ≥ 1, then if the integral of f(n) from 1 to infinity converges, the series also converges. If the integral diverges, the series diverges.

It is important to note that the Integral Test is only one method of determining the convergence or divergence of a series and that it has some limitations such as it only works when the function f(n) is positive and decreasing. Also, the test is only inconclusive if the necessary conditions are not met, so statement 4 and 5 are not true.

The numbered spot at which all the runners will be next to one another is spot 19.

Least Common Multiple is the meaning of the acronym LCM. The lowest number that may be divided by both numbers is known as the least common multiple (LCM) of two numbers. It may also be computed using two or more real numbers.

Starting with the runner on the outside track, the provided parameters are;

The runner covered n₁ = 5 places on the outside track, which is the number of spaces.

Next, the inner runner will traverse n₂ spaces, which equals one space.

The following inner runner will cover n₃ = 3 spaces.

The subsequent runner will traverse n₄ = 2 spaces.

The Lowest Common Multiple, or LCM, of all the runners' speeds or the total number of spaces they cover in the same amount of time, determines where all the runners will be placed next to one another.

LCM(5, 1, 3, 2) = 30 is the LCM of 5, 1, 3, and 2.

Time = 30/ = 6

Consequently, when the first runner has covered 30 places, we have;

Six time units have been expended.

The runner comes to a stop at position 30- (30 -19) = Position 19.

First runner's new destination is Spot 19.

The distance covered simultaneously by runner 2 is 6 x 1 = 6.

The distance covered by two runners running simultaneously equals six spaces.

Second runner's new position: 6 spaces plus spot 13 equals spot 19.

The combined distance covered by the three runners is 6 x 3 = 18.

The distance runner 3 covers 18 spaces simultaneously.

Third runner's new position: 18 spaces + Spot 1 = 19 spaces

Runner 4 covers a distance of 6 x 2 = 12 at the same time.

Distance runner 4 journeys equals 12 spaces

Runner 4's new position is now 12 spaces Plus Spot 7 = Spot 19.

Therefore, all the runners will be next to one another is spot 19.

So, the area of the stripe is 394.25= 282.75 square feet.

The stripe is a rectangle, with a width of 3 feet and a length that is the circumference of the cylinder. The diameter of the cylinder is 30 feet, so the circumference is 30pi=94.25 feet. So, the area of the stripe is 394.25= 282.75 square feet.

The white cylindrical silo has a red stripe painted on it, which makes two complete revolutions around the silo. The stripe is a horizontal rectangle with a width of 3 feet and a length equal to the circumference of the cylinder, which is calculated by multiplying the diameter of 30 feet by pi.

The constant of proportionality in this proportional relationship is 5/4.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 5 is an equation.

We have,

Let the proportional equation be y ∝ x.

y = kx

From the table,

When x = 2, y = 5/2

This means,

5/2 = 2k

k = (5/2)/2

k = 5/4

Now,

When x = 2(1/2), y = 25/8

k = y/x

k = (25/8)/(5/2)

k = 25/8 x 2/5

k = 5/4

We see that,

k = 5/4

Thus,

The constant of proportionality is 5/4.

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, You are getting paid $50 per hour and at the end of the day, you earned $400.

Answer:

6, 8

Step-by-step explanation:

2  and 3 are factors of 6. So, if number is divisible by 6, then the same number is divisible by 2 and 3.

Eg: 12 is divisible by 6. So, 2 and 3 will divide 12.

4 and 2 are factors of 8.  if number is divisible by 8, then the same number is divisible by 4 and 2.

Eg: 48 is divisible by 8. So, 4 and 2 will divide 48.

So, to find the least number that is divisible by 2, 3, 4, 6 and 8, then the only two factors that we need to use are 6 and 8.

After 15 minutes of walking, Julia and Josie are facing each other at the same point (in distance).

Distance between Julia and Josie = 1,500 m

Julia's traveling rate (speed) per hour = 2,000 mph

The smallest positive integer such that (2k)(5200) has 303 digits is k = 151. In order to calculate the sum of the digits of this number, we will first expand the expression (2k)(5200). This expression can be expanded to 10302k. The sum of the digits of this number is equal to 1 + 0 + 3 + 0 + 2 + k. Since k = 151, the sum of the digits of this number is equal to 1 + 0 + 3 + 0 + 2 + 151 = 157. Therefore, the sum of the digits of the number 10302k, when k = 151, is 157.

Deviation refers to how far a value or set of values is from the mean or average. In statistics, the standard deviation is a measure of the spread of a dataset, calculated as the square root of the variance. It represents the average distance of each data point from the mean. A low standard deviation indicates that the data points tend to be close to the mean.

To compute the probabilities for a standard normal random variable, we can use a standard normal table or a calculator with standard normal distribution functions.

P(z ? -1.0) = P(z < -1.0) = 0.1587

P(z ? -1.0) = P(z > -1.0) = 1 - 0.1587 = 0.8413
