Equation can be solced to find t

Answer:

Step-by-step explanation:

This is a geometric sequence because each new term is a multiple (actually, "negative half of the previous term").

If the original population were Po, then the population after d days is

P = Po(0.5)^(d - 1)

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

In graphical form, the normal distribution appears as a "bell curve".

The normal distribution is the proper term for a probability bell curve.

In a normal distribution the mean is zero and the standard deviation is1. It has zero skew and a kurtosis of 3.

Normal distributions are symmetrical, but not all symmetrical distributions are normal.

The t-distribution describes the standardized distances of sample means to the population mean when the population standard deviation is not known, and the observations come from a normally distributed population.

Therefore,

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.

Answer:

a = -7/17

Step-by-step explanation:

Add -4a to -2a

This makes -6a. Then you add 6a to the left to cancel it out, but you must also add 6a to the right of the =

Divide 17 from both sides and you have -7/17 = a

To find the interval of convergence of the power series ∑n=1∞ (2x+5)^n/n3^n, we will use the ratio test:
lim┬(n→∞)⁡|(2x+5)^(n+1)/(n+1)3^(n+1)|/|(2x+5)^n/n3^n)|
= lim┬(n→∞)⁡|(2x+5)/(n+1)(3/2)| = 0
Thus, the interval of convergence for the given power series is (-3, -2).

Since the limit is less than 1 for all values of x, the series converges for all x. Therefore, the interval of convergence is (-∞, ∞).
The interval of convergence for the given power series ∑(2x+5)^n/(n*3^n) can be found using the Ratio Test.

First, we'll find the limit as n approaches infinity:
L = lim (n → ∞) |((2x+5)^(n+1))/((n+1)*3^(n+1)) * (n*3^n)/((2x+5)^n)|

This simplifies to:
L = lim (n → ∞) |(2x+5)(n*3^n)/(n+1)*3^(n+1)|

Cancel the common terms:
L = lim (n → ∞) |(2x+5)n/(n+1)|

For the series to converge, we need L < 1:
|(2x+5)n/(n+1)| < 1

Since we're interested in the interval of convergence, we can ignore the n term:
|2x+5| < 1

Now solve for x:
-1 < 2x+5 < 1
-6 < 2x < -4
-3 < x < -2

Thus, the interval of convergence for the given power series is (-3, -2).

At the end of the fifth day, a bricklayer has laid 324 bricks on the job.

Multiplication is a mathematical arithmetic operation.

It is also a process of adding the same types of expression to some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given, a bricklayer lays 4 bricks on the first day on the job.

On each day thereafter, he lays three times the number of bricks he laid on the previous day.

And he continued his pattern.

Let x be the number of bricks he laid in the previous day.

Then according to the question,

The number of bricks in total is = 3x

For the second day, x =4

Number of the bricks he laid on the second day = 12

Now the x =12 for the third day.

Number of the bricks he laid on the third day = 36

Now x = 36 for the fourth day.

Number of the bricks he laid on the fourth day = 108

Now the x = 108 for the fifth day.

Step-by-step explanation:

Poles are usually standing vertical, thus at right angle with the ground. The length of tree touching the top of pole is given by: Option D: 17 feet.

A right angled triangle is a triangle having one of its angle with measure of 90 degrees.

The slant side(leaning side) of that triangle is called Hypotenuse and it is the longest side in that triangle.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

\(|AC|^2 = |AB|^2 + |BC|^2\)

Where |AB| = length of line segment AB.

We can use the fact that the pole is standing vertical, the tree is leaning on it, so there is right angled triangle formation, and thus, we can use Pythagoras theorem.

Consider the graph attached below.

The tree is AC, The pole is AB and the distance of pole's bottom from the bottom of the tree is denoted by length of BC

We're already given that:

Pole length = |AB| = 15 feet

Distance between bottom of pole to bottom of tree = |BC| = 8 feet

The length of tree is |AC| = x feet (assume)

Then, by the Pythagoras theorem, we get:

\(x^2 = 15^2 + 8^2\\\\x = \sqrt{225 + 64} \text{\: (We took positive root since length is a non negative quantity)}\\\\x =\sqrt{289} = 17 \: \rm feet\)

Thus, length of AC = |AC| = 17 feet.

Thus,

The length of tree touching the top of pole is given by: Option D: 17 feet.

There are 720 unique ways to award the gold, silver, and bronze medals to the top three participants in this contest.

The number of unique ways to award the gold, silver, and bronze medals can be determined by using the concept of permutations. A permutation is an arrangement of objects in a specific order. In this case, we need to find the number of permutations of 10 participants for the top three positions.

The number of permutations of 10 participants for the gold medal can be calculated as 10P1, which is equal to 10. This means that there are 10 different participants who can receive the gold medal.

Once the gold medalist is determined, there are only 9 participants remaining for the silver medal. The number of permutations of 9 participants for the silver medal can be calculated as 9P1, which is equal to 9. This means that there are 9 different participants who can receive the silver medal after the gold medalist is determined.

Finally, once the gold and silver medalists are determined, there are only 8 participants remaining for the bronze medal. The number of permutations of 8 participants for the bronze medal can be calculated as 8P1, which is equal to 8. This means that there are 8 different participants who can receive the bronze medal after the gold and silver medalists are determined.

To determine the total number of unique ways to award the medals, we need to multiply the number of permutations of each medal. Therefore, the total number of unique ways to award the medals is equal to:

10P1 x 9P1 x 8P1 = 10 x 9 x 8 = 720

Therefore, there are 720 unique ways to award the gold, silver, and bronze medals to the 10 participants in this contest.

The probability that the mean annual precipitation of a sample of 49 randomly picked years will be less than 92.8 inches is, 0.9192

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

Given: The annual precipitation amounts in a certain mountain range are normally distributed with a mean of 90 inches, and a standard deviation of 14 inches.

z score is given by,

z = (x - μ)/(σ/√n) = (92.8 - 90)/(14/√49) = 2.8/2 = 1.4

The  required probability is,

p(z < 1.4) = 0.9192, by standard normal table.

Step-by-step explanation:

Answer:

9.52

Step-by-step explanation:

What is 136% of 7?

Y is 136% of 7

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 136% * 7

Converting percent to decimal:

p = 136%/100 = 1.36

Y = 1.36 * 7

Y = 9.52

to determine which items are within tolerance, we compare their values to the specified range. To calculate the percent accuracy, we find the difference between the measured value and the target value, and then divide it by the target value.

a) To determine which items are within tolerance, we need to compare each item's value to the acceptable range specified by the tolerance. If an item's value falls within this range, it is considered to be within tolerance. Let's say we have three items with their respective values and tolerances:
Item 1: Value = 10, Tolerance = ±2
Item 2: Value = 7, Tolerance = ±1.5
Item 3: Value = 5, Tolerance = ±0.5
For Item 1, since 10 falls between 10-2=8 and 10+2=12, it is within tolerance.
For Item 2, since 7 falls between 7-1.5=5.5 and 7+1.5=8.5, it is also within tolerance.
For Item 3, since 5 falls between 5-0.5=4.5 and 5+0.5=5.5, it is within tolerance as well.
Therefore, all three items are within tolerance.
b. To calculate the percent accuracy by item, we need to determine the difference between the measured value and the target value, and then divide it by the target value. This difference is then multiplied by 100 to obtain the percent accuracy.
Using the same values as before:
Item 1: Value = 10, Target Value = 9
Item 2: Value = 7, Target Value = 6
Item 3: Value = 5, Target Value = 4
For Item 1, the difference is 10-9=1. The percent accuracy is (1/9) x 100 = 11.11%
For Item 2, the difference is 7-6=1. The percent accuracy is (1/6) x 100 = 16.67%
For Item 3, the difference is 5-4=1. The percent accuracy is (1/4) x 100 = 25%.Therefore, the percent accuracy by item is 11.11%, 16.67%, and 25% for Items 1, 2, and 3 respectively.
