Can someone please answer this with solution please , it's scientific notation.. it's my homework since December 16

A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?

Elodia [21]

Answer:

28 ft²

Step-by-step explanation:

The area of a circle is $\pi r^2$ , where r = radius. To find the radius, we split the diameter in half.

6/2 = 3
Thus, the radius is 3.

Now, let's find the area of the circle and approximate pi to 3.14.

$3.14*3^2$
$3.14*9$
$28.26$
28.26 ≈ 28 ft²

Therefore, the answer is 28 ft².

Marco would like to hang a banner over his shoe store. He has two ladders and would like to know how high above the ground each

13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.

Pls explain how to solve it!

Sophie [7]

Answer:

a = jd

Step-by-step explanation:

We want to solve for a given that a/d = j

To do so we want to isolate a (get a by itself )

We can do this by using inverse operations.

We would want to get rid of the d

A is being divided by d.

The inverse of division is multiplication so to get rid of the d we multiply a/d by d but whatever we do to one side we must do to the other so we multiply both sides by d

a/d * d = a

j * d = jd

we are then left with a = jd

And we are done!

A researcher is interested in the lengths of brook trout, which are known to be approximately Normally distributed with mean 80

aliya0001 [1]

Answer:

$P(X$

And we can find this probability with the normal standard distirbution or excel and we got:

$P(z$

Step-by-step explanation:

Previous concepts

Normal 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".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:

$X \sim N(80,5)$
