The probability of getting the 6 on the first die given that the minimum of two numbers is 4 would be 0.11.
What is the probability?
Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.
Two dice are rolled.
Then the sample space (n) = 36
Possible outcomes = {(6,1), (6, 2), (6, 3), (6, 4)}
Probability = 4/36
= 0.11
Hence, the probability of getting the 6 on the first die given that the minimum of two numbers is 4 would be 0.11.

is the square root of open paren x negative 3 close paren squared equals 3 negative x ? (1) x is not equal to 3 (2) negative x times the absolute value of x is greater than 0
The square root of open paren x negative 3 close paren squared =
3 negative x negative x times the absolute value of x is greater than 0.
Let the equation be: |x−3|=3−x|x−3|=3−x
When x>3x>3, then RHS is negative, but LHS (absolute value) is never negative, hence in this case equations doesn't hold true.
When x≤3x≤3, then LHS=|x−3|=−x+3=3−x=RHSLHS=|x−3|=−x+3=3−x=RHS
x≠3x≠3
Thus,
−x|x|>0−x|x|>0, this inequality implies that x<0x<0, hence x<3x<3.
Hence option b becomes the correct option i.e, negative x times the absolute value of x is greater than 0.

Answer: 67 87 34
Step-by-step explanation:
let $w 1, w 2, \dots, w n$ be complex numbers. a line $l$ in the complex plane is called a mean line for the points $w 1, w 2, \dots, w n$ if $l$ contains points (complex numbers) $z 1, z 2, \dots, z n$ such that \[\sum {k
The slope of the line is going to be m = 163.
Here, we have been told that the sum of the numbers is going to be -
= ∑[tex]w _{k}[/tex]= 3 + 504i (i)
The other set of complex numbers is (z₁, z₂, ....[tex]z_{k}[/tex]) and their sum is going to be = ∑[tex]z_{k}[/tex]= 3 + 504i (ii)
If we write the number 3+504i in the standard form for complex numbers i.e., a+bi with respect to the summations, we get -
= ∑[tex]a_{k}[/tex]= 3 (III)
= ∑[tex]b_{k}[/tex]= 504 (Iv)
The standard equation is of the form, y = mx+3. Substituting the polar coordinates, we get -
= [tex]b_{k}[/tex] = m[tex]a_{k}[/tex] + 3
Now, if we use all of the given values in equations (iii) and (iv) for k, we get -
= 504 = 3m + 15
Now, on simply solving for m, we get -
= 3m = 504 - 15 = 489
= m = 489/3
= m = 163
Henceforth, we find out that the slope of the line, m is 163.

the volume of a gas in a container varies inversely with the pressure on the gas. if a gas has a volume of 500 cubic inches under a pressure of 14 pounds per square inch, what will be its volume if the pressure is increased to 19 pounds per square inch? (round off your answer to the nearest cubic inch.)
If the pressure is increased to 19 pounds per square inch, then the volume is 368.42 cubic inches
The volume of the gas = 500 cubic inches
The pressure = 14 pounds per square inch
The volume of a gas in a container varies inversely proportional with the pressure on the gas.
V ∝ 1/P
Where V is the volume and P is the pressure
Then,
V = k/P
Where k is the constant
500 = k/14
k = 500 × 14
k = 7000
The pressure of the gas = 19 pounds per square inch
Volume = 7000 /19

A sample of 68 is needed if we wish to be 96% confident that our sample mean will be within 10 hours of the true mean for the standard deviation of 40 hours
Since a level =1-0.96/2 =0.02, here the Z value of 1-a = 1-0.02= 0.98 , for which z=2.055 .Now we know that the formula for margin is:
M = z*σ/√n, where σ is the standard deviation and n is the sample size since we are provided with the standard deviation of 40 and M=10. so,
=> 10= 2.055*40/√n
=>10√n= 2.055*40
=>√n = 82.2/10
=>n=67.6 ,which is almost 68

question content area top part 1 a pair of dice is rolled. what is the probability of getting a sum less than 5?
When a pair of dice is rolled, there is a 1/6 chance that the result will be less than 5.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution. The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event might occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
Here,
Total possibility=36
To calculate the probability correctly, the list should be,
(1,1),(1,2),(1,3),(2,1),(2,2),(3,1)

Using the binomial distribution, it is found that there is a 0.5954 = 59.54% probability that at least 1 is defective.
What is the binomial distribution?
A collection of numerous independently distributed Bernoulli trials with equal distributions results in the binomial distribution. The experiment in a Bernoulli trial is said to be random and can only result in one of two outcomes: success or failure.
For each phone, there are only two possible outcomes, either it is defective, or it is not. The probability of a phone being defective is independent of any other phone, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_n, x. p^{x.(1-p)^n-x}[/tex]
[tex]C_n, x = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.
n is the number of trials.
p is the probability of success on a single trial.
In this problem:
0.11 probability of a single phone is defective, hence
6 phones are selected at random, hence
The probability that at least 1 is defective is:
P(X >= 1) = 1 - P(X = 0)
In which
[tex]P(X = x) = C_n, x. p^{x.(1-p)^n-x}[/tex].
P(x = 0) = C₆,₀.(0.11)⁰ (0.86)⁶ = 0.4046
Then:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.4046 = 0.5954
Hence, the 0.5954 = 59.54% probability that at least 1 is defective.

A random selection of an Endure All battery has a 10.56% probability of lasting more than 550 hours.
Explain the term z score?A Z-score is a metric that quantifies how closely a value relates to a mean of a set of values. Standard deviations as from mean are used to measure Z-score. A Z-score of zero means the data point is entirely score is the same as the mean score.The Z score is utilized to calculate how far the raw score deviates from the mean.
The Z score is calculated as follows:
z = (x - μ)/σ
Given that x > 550 and μ = 500, σ = 40:
z = 550 - 500 / 40
z = 1.25
Following the normal distribution chart,
P(z > 1.25) = 1 - P(z < 1.25)
P(z > 1.25) = 1 - 0.8944
P(z > 1.25) = 0.1056

Solve for y:
If -3x + 9y = -21, and -3x +8y = -18, then -21 - y = -18
Add 18 to both sides:
-3 - y = 0, so y = -3
reconstruct new equation:
-3x + 9(-3) = -21, -3x + 8(-3) = -18
-3x + -27 = -21, -3x + -24 = -18
Using the new equation, solve for x:

The population size after four days is 121.
Given that,
a population of protozoa with a constant relative growth rate of 0.8603 per member per day
let P be the population size and let t be the time interval then the given system modeled by the differential equation
[tex]\frac{dP}{dt}[/tex] = 0.8603

P = A [tex]e^{0.8603t}[/tex]
From the condition that on day zero the population consist of four members,
i.e. P(0) = 4, A = 4
Therefore population size after four days is
P(4) = 4[tex]e^{4(0.8603)}[/tex]
