Answer:
(a) 8 balls
(b) 4 balls
Step-by-step explanation:
Let
Number of balls
For a box, the probability that there are N balls in it is:

For 2 boxes, it is:

From the question, we have:
Favorable outcome
To solve for N, we have:


Divide both sides by 2

Take log of both sides

Apply law of logarithm

Make N the subject


Approximate

Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:



<em>4 balls in each box</em>
Using the normal distribution, it is found that due to the greater z-score, Stewart caught the longer fish relative to the same specie.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
To find who caught the longer fish relative to the same specie, we need to find out who had the higher z-score.
Stewart caught a bluefish with a length of 322 mm, hence the parameters are as follows:

The z-score is:


Z = 1.41
Gina caught a pompano with a length of 176 mm, hence the parameters are as follows:

The z-score is:


Z = 0.75.
Hence Stewart caught the longer fish relative to the same specie.

We know that
<span>Since a circle is 360 degrees,
then
360</span>°-----------> 100%
<span>x </span>°----------> <span>15%
</span>x=15*360/100-----> x=54°
the answer is
54 degrees
Answer:
(25)^2*(9)^2*(4squreroot2)^2*(7squreroot2)^2
Step-by-step explanation:
5^4*3^3*2^5*343
=(25)^2*(9)^2*(4squreroot2)^2*(7squreroot2)^2
Answer:
7.08
Choice A
Step-by-step explanation:
From the right-angled triangle we have been given the following;
One angle - 33 degrees
The hypotenuse - 13 units
We are required to determine the length of the side, opposite the angle, marked x.
Using the Mnemonic; SOHCAHTOA
The sine of an angle is; (opposite side)/(hypotenuse)
Therefore;
sin 33 = x/13
x = 13 * sin 33
x = 7.080
