Options:
A.) decrease because the same five numbers are not likely to occur again so soon.
B.) Increase because those five numbers must be lucky.
C.) be unaffected because every set of five numbers is equally likely on every attempt.
D.) be unknown because it depends on how many times those five numbers have won in the last several drawings.
Answer:
be unaffected because every set of five numbers is equally likely on every attempt.
Step-by-step explanation:
Number selection in the lottery is randomized with each set of number having equal chances of being selected. This means that each and every selection attempt is independent and the outcome of each attempt does not depend on any prior outcome or event. This means that if the numbers drawn from the most previous prior drawing are selected on the next attempt, the probability of winning on the next attempt Neither increases nor decreases. Hence , the probability of winning on the next attempt with this selection is unaffected.

how do you find and (draw) graph slope.
Answer:
y=-x+4
The equation is in the form y=mx+c, where m is the slope and c is the y-intercept, so we know that the slope (m) is -1, and the y-intercept (c) is 4.
The y-intercept is the value of y when x=0. So you can mark (0,4) as a point on the line.
The next thing I would do is take any value for x and find another point on the line. Let's let x=2:
y=-2+4
y=2
So now we know another point on the line (2,2). Mark this on the graph too.
Then connect these two points and extend to the line to finish off your graph, and you're done!
(PS: if the whole 'y-intercept' thing gives you a headache, you can just pick any two values for x, sub them in to find the points, mark those points and connect. There's also a method for graphing using just the slope and y-intercept, but the method above is usually what people prefer to do)

The area of a square mural is 144x2 - 72x + 9. What is the length of one side
of the mural?
Answer:
-0.25 units
Step-by-step explanation:
144x^2 - 72x + 9 = 0
common factor: 9
16x^2 - 8x + 1 = 0
(4x + 1)^2 = 0
4x +1 = 0
4x = -1
x = -0.25 units

WILL GIVE BRAINLEST!!!!!! Which system of equations can be solved using this matrix equation?
Answer:
b
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Matrix notation can be confusing, but it's important to remember that systems of equations are typically written as follows:
#x + #y + #z = #
so if there was only one equation it would be written like this:
[tex]\left[\begin{array}{ccc}5&2&1\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = [16]\\\\5x + 2y + z = 16\\[/tex]
Then just follow the same pattern for the remaining equations

Web crawlers need to estimate the frequency of changes to Web sites to maintain a current index for Web searches. Assume that the changes to a Web site follow a Poisson process with a mean of 6 days. Let a random variable X denote the time (in days) until the next change. Round your answers to three decimal places (e.g. 98.765)
a) What is the probability that the next change occurs in less than 4.5 days?
P(X <4.5)=
b) What is the probability that the time until the next change is greater 9.5 days? P(X> 9.5) =
c) what is the time of the next change that is exceeded with probability 90%? x = _______day(s)

Research indicates that many Americans do not save enough for retirement, on average. A group of economists at the Federal Reserve Bank of St. Louis are interested in conducting a study to examine whether Americans between the ages of 55 and 65 have saved too little. The analysts obtain a random sample of Americans in this age group and proceed to test if there is evidence of insufficient savings from these data. The variable considered is the total amount of savings for each individual, reported in thousands of US dollars (i.e. if value 3 appears in the data set, it stands for $3,000.)
Required:
Assume that financial specialists suggest that the minimum level of retirement savings should be 1.5 million US dollars. Use the JMP output to report the value of the test statistic used to gather evidence against the null hypothesis.

Use the JMP output to report the value of the test statistic used to gather evidence against the null hypothesis. Report your answer as a number ( no symbols ) and round up to two decimal places.
Test mean
Hypothesized value : 1500
Actual Estimate : 1613.07
DF : 251
Std Dev : 782.626
t Test
prob > |t| 0.0226*
Answer:
the value of the test statistic used to gather evidence against the null hypothesis is 2.29
Step-by-step explanation:
Given the data in the question,
we determine Test statistics of using the formula
t = (x" - μ) / (s/√n)
where;
μ is the theoretical mean ( 1500 )
x" is the observed mean ( 1613.07)
s is the standard deviation ( 782.626 )
n is the sample size ( DF = n - 1, n = DF + 1 , n = 251 + 1 = 252 )
so we substitute
t = (1613.07 - 1500 ) / (782.626 / √252)
t = 113.07 / 49.3008
t = 2.29
Therefore, the value of the test statistic used to gather evidence against the null hypothesis is 2.29
