Answer: Poisson distribution
Step-by-step explanation:
The Poisson distribution simply measures the chance for an event occuring based on a particular period of time. It is typically useful for finding the probability of events that have low probabilities of occuring.
Therefore, the distribution that will be ideal in knowing the number of fatalities in Texas in a given year due to poisonous snakebites is the poisson distribution.

[i] Area of Juan's garden:
Soln,
length(l)=16
width(w)=12
area(a)=?
Now,
a=l×w
=16×12
=192
[ii] Area of Matthew's garden:
Soln,
length(l)=18
width(w)=21
area(a)=?
Now,
a=l×w
=18×21

Ronald scores 700 on the math section of the SAT exam. The distribution of SAT scores is approximately normal with a mean of 500 and a standard deviation of 100. Rubin takes the ACT math exam and scores 31 on the math portion. ACT scores are approximately normally distributed with a mean of 18 and a standard deviation of 6.7
(a) Relative to their peers who also took the tests, who performed better on his test? Explain.
(b) A certain school will only consider those students who score in the top 1% in the math section. What grades would Ronald and Rubin have to receive on their respective tests to be considered for admission?
(c) Between what two grades does 95% of the population fall for the ACT and the SAT exams?
Answer:
a) Due to the higher z-score, Ronald performed better relative to his peers on the test.
b) Ronald needed a grade of at least 732.5, and Rubin of at least 33.58.
c) 95% of the population fall between graded of 4.868 and 31.132 on the ACT.
95% of the population fall between graded of 304 and 696 on the SAT.
Step-by-step explanation:
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
(a) Relative to their peers who also took the tests, who performed better on his test? Explain.
We have to find whoever has the higher z-score.
Ronald:
Ronald scores 700 on the math section of the SAT exam. The distribution of SAT scores is approximately normal with a mean of 500 and a standard deviation of 100. So the z-score is found when [tex]X = 700, \mu = 500, \sigma = 100[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{700 - 500}{100}[/tex]
[tex]Z = 2[/tex]
Rubin:
Rubin takes the ACT math exam and scores 31 on the math portion. ACT scores are approximately normally distributed with a mean of 18 and a standard deviation of 6.7. So the z-score is found when [tex]X = 31, \mu = 18, \sigma = 6.7[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{31 - 18}{6.7}[/tex]
[tex]Z = 1.94[/tex]
Due to the higher z-score, Ronald performed better relative to his peers on the test.
(b) A certain school will only consider those students who score in the top 1% in the math section. What grades would Ronald and Rubin have to receive on their respective tests to be considered for admission?
They have to be in the 100 - 1 = 99th percentile, that is, they need a z-score with a pvalue of at least 0.99. So we need to find for them X when Z = 2.325.
Ronald:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.325 = \frac{X - 500}{100}[/tex]
[tex]X - 500 = 232.5[/tex]
[tex]X = 732.5[/tex]
Rubin:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.325 = \frac{X - 18}{6.7}[/tex]
[tex]X - 18 = 15.58[/tex]
[tex]X = 33.58[/tex]
Ronald needed a grade of at least 732.5, and Rubin of at least 33.58.
(c) Between what two grades does 95% of the population fall for the ACT and the SAT exams?
They fall between the 100 - (95/2) = 2.5th percentile and the 100 + (95/2) = 97.5th percentile, that is, they fall between X when Z = -1.96 and X when Z = 1.96.
ACT:
Lower bound:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - 18}{6.7}[/tex]
[tex]X - 18 = -1.96*6.7[/tex]
[tex]X = 4.868[/tex]
Upper bound:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.96 = \frac{X - 18}{6.7}[/tex]
[tex]X - 18 = 1.96*6.7[/tex]
[tex]X = 31.132[/tex]
95% of the population fall between graded of 4.868 and 31.132 on the ACT.
SAT:
Lower bound:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - 500}{100}[/tex]
[tex]X - 500 = -196[/tex]
[tex]X = 304[/tex]
Upper bound:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.96 = \frac{X - 500}{100}[/tex]
[tex]X - 500 = 196[/tex]
[tex]X = 696[/tex]
95% of the population fall between graded of 304 and 696 on the SAT.

A box contains 5 red marbles, 6 white marbles, and 4 blue marbles. Find
P(red or blue)
Answer: 3/5
Step-by-step explanation:
Probability is the number of favorable outcomes divided by the total number of outcomes. In this case, there are 5+4+6, or 15, possible outcomes, because there is one selection from 15 marbles. Therefore, the probability of choosing a blue marble is 4/15, and the probability of choosing a red marble is 5/15. Add these together to get the probability of choosing a red or blue marble:
(4/15)+(5/15)=9/15
9/15 simplifies to 3/5.

What is the period of y= sec X?
Given:
The given function is
[tex]y=\sec x[/tex]
To find:
The period of given function.
Solution:
General sec function is defined as
[tex]y=A\sec (Bx+C)+D[/tex]
Where, A is amplitude, [tex]\dfrac{2\pi}{B}[/tex] is period, [tex]-\dfrac{C}{B}[/tex] is phase shift and D is vertical shift.
We have,
[tex]y=\sec x[/tex]
Here, B=1. So,
[tex]Period=\dfrac{2\pi}{1}[/tex]
[tex]Period=2\pi[/tex]
Therefore, the period of given function is 2π.
The value of period of function y = sec x is, 2π.
The given function is,
y = sec x
Since, We know that,
General form of equation for sec x is,
y = A sec (Bx + C) + D
Where, A is amplitude, 2π/B is period and D is vertical shift.
Here, function is,
y = sec x
Hence, B = 1,
So, Period = 2π/B
= 2π/1
= 2π
Thus, The value of period of function y = sec x is, 2π.

Is 3/9 more less or equal to 5/8
Answer:
less
Step-by-step explanation:
Answer:
3/9 is less that 5/8
Step-by-step explanation:
To answer this question we can simply infer which is greater by using simple knowledge.
We know that 1/9 and 1/8 are both relatively small parts of a whole.
Now we know that 1/8 is greater than 1/9
If we think about it 5/8 is bound to be greater than 3/9 because the parts of a whole when you are dealing with 8ths are greater than when you are dealing with 9ths and since there are more 8ths than 9ths in the comparison as in (3 < 9) then we should already know that:
5/8 is greater than 3/9

Sam found a wrecked car that could she could fix. She bought the car for
65% of the original price of $7200. What did she pay for the car? SHOW YOUR WORK
$11,076.92
$4,680
$2,520
$468
=======================================================
Work Shown:
x% = x/100
65% = 65/100 = 0.65
So 65% in decimal form is 0.65
We use this to find the amount Sam paid for the car
65% of 7200 = 0.65*7200 = 4,680 dollars
--------------
Here's an alternative way to show your work
part/whole = percent/100
x/7200 = 65/100
x/7200 = 0.65
x = 0.65*7200
x = 4680
Ultimately we end up with 0.65*7200 and that's how we lead to the same answer as before. You could cross multiply like so
x/7200 = 65/100
x*100 = 7200*65
100x = 468000
x = 468000/100
x = 4680
So there are many paths to the same answer.
