The correct relation for the sea gull population is: P(t) = 5.3t^(11/7)

Answer:

d. about 66.5 hundred thousand

Step-by-step explanation:

Given that :

P(t) = 5.3t^(11/7)

Population, P is in hujdred thousand ; t = number of years

Population after 5 years ;

t = 5

P(5) = 5.3 * 5^(11/7)

P(5) = 5.3 * 5^1.5714285

P(5) = 5.3 * 12.542422

P(5) = 66.474840

P(5) = 66.5 (approximately)

Hence, population after 5 years will be about 66.5 hundred thousand.

The ages of dogs at an animal shelter are normally distributed with a mean of 3.9 years and a standard deviation of 1.2 years.

Aleks [24]

Answer:

The correct answer is A. 1.86 years

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Mean of the dogs at an animal shelter = 3.9 years

Standard deviation = 1.2 years

2. What is the age of a dog at the shelter with a z-score of −1.7 ?

Let's recall that z-score in a normal distribution, positive or negative, is the number of times of the standard deviation a certain element is from the mean. If the element is below the mean, then the z-score is negative and if it's above the mean, then the z-score is positive.

Therefore, a z-score of - 1.7 for the ages of dogs is:

-1.7 * 1.2 = -2.04

Now, we calculate the value using the mean, this way:

3.9 + -2.04 = 3.9 - 2.04 = 1.86

The correct answer is A. 1.86 years

Alex is mailing an envelope that weighs 0.346 pounds.What is the weight of the envelope rounded to the nearest hundredth

tangare [24]

The hundredth place is the second number on the right side of the decimal place. In this case, it is the 4 in the number you listed above.

Rounding is simple, once you get the hang of it. :)

To round on the right side of the decimal, you look at the number to the right of the number. If the number to the right of that number is five or over, the number rounds up. But, if it is less than five, the number remains the same. Either way, the number/s to the right of the one you are rounding disappear after you are done.

So let's look at your equation. The number you wish to round up- the hundredths place is the number 4. The number to the right of the four is a six. Since that is five or over, we round up. So the number would end up being .35 pounds to the nearest hundredth.

Thanks for the opportunity to answer your question and I hope I helped! If I answered your question, please consider nominating me for the brainliest answer, friending me, or even leaving a comment on my profile! Thank you!! :)

Estimate by rounding to the nearest hundred. Show your work. 12,846 - 3467

Rufina [12.5K]

Answer:

9,400

Step-by-step explanation:

12,846 - 3,467 = 9,379

The hundreds digit is 3.

So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.

Then, your answer is (9,400)

Hope this helps ; )

Factor the GCF: −6x4y5 − 15x3y2 + 9x2y3 (5 points)

MissTica

-6x^4y^5-15x^3y^2+9x^2y^3

The GCF OF -6, -15, & 9, is -3
The GCF OF x's is x^2
The GCF OF y's is y^2
These are the number of x's and y's that each term has.
-3x^2y^2(2x^2y^3+5x-3y)
