find three vectors with which you can demonstrate that the vector cross product need not be associative, i.e., that a x (b x c) need not be the same as (a x b) x c. g
The cross product of three vectors is not associative in nature.
Considering three vectors such as : A=(2,1,3), B=(1,0,2) and C=(1,1,0)
we know that the associative law depicts that :
A x (B x C) = (A x B) x C ,while doing the operation for the considered vectors :
A x (B x C) =(2,1,3)x ((1,0,2)x (1,1,0))
=(2,1,3)x (-2,2,1)
=(-5,-8,6)
(A x B) x C= ((2,1,3)x (1,0,2))x (1,1,0)
= (2,-1,1) x (1,1,0)
=(-1,1,3)
So for this vector operation, A x (B x C) is not equal to (A x B) x C, so you can sum up that cross product of three vectors can't be associative every possible time.

Kehlani has p pennies and n nickels. She has at least 20 coins altogether. Write this situation as an inequality.
During a snowstorm, Eva tracked the amount on the ground. When the storm being, there was no snow on the ground. Snow feel at a constant rate of 3 inches per hour until 6 inches had fallen. The storm then stopped for 5 hours and then started again at a constant rate of 2 inches per hour for the next 2 hours. As soon as the storm stopped again the sun came out and melted the snow for the next 2 hours at a constant rate of 4 inches per hours
Answer:
2 inches of snow was left on the ground
Step-by-step explanation:
To calculate the amount of snow on the ground we can take it one step at a time. Since there was no snow on the ground we can start at a level of 0. Then it snowed until 6 inches of snow had fallen, so we can add that to our total.
0 + 6 = 6 inches
Next, it snowed for 2 more hours at a rate of 2 inches per hour, meaning we multiply this by 2 hours and add to the total amount of snow that was already on the ground.
(2*2) + 6 = 10 inches
Lastly, the sun came out and melted the snow on the ground for 2 hours at a rate of 4 inches per hour. Since it is melting the snow, this means that it is subtracting the snow from the total. So we would have to multiply the rate (4 inches per hour) by the number of hours and then subtract that from the amount of snow on the ground.
10 - (4*2) = 2 inches

Answer:
$305.9022863 or $305.90 (rounded to 2 decimal places)
Step-by-step explanation:
It is a compound interest, meaning an interest accumulates on an initial amount every period. The formula
A= P(1+R)^n
A= the total amount P=Initial amount R= rate n=time period
P=$100 R=15% or 0.15(decimal) n=8 (years)
A= 100 (1.15)^8
A= 100(3.059022863)
A=305.9022863
The amount you will have after 8 years is $220
Calculating simple interestThe formula for calculating simple interest is expressed as:
SI =PRT
P is the principal = $100
T is the time = 8 years
R is the rate. = 15%
SI = 100 * 8 * 0.15
SI = $120
Amount after 8years = $100 + $120
Amount after 8years = $220

Step-by-step explanation:
Hey There!
Look at the image for the rule of a 30- 60 - 90 triangle
x = 5
the hypotenuse would be x2 so 10
the longer leg would be x\(\sqrt{3}\)
So the first triangle is the right answer
The first triangle in the figure is a 30°-60°-90° triangle.
What is a triangle?A triangle is a polygon with three sides and three angles.
Given are triangles, we need to see which of them are a 30°-60°-90° triangle,
So,
In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse.
So you have to choose one with 5 & 10.
Use the Pythagorean theorem to calculate the remaining side
a² + b² = c²
5² + b² = 10², so b² = 100-25 √b²=√75 so √(25)(3)
b= 5√3
Hence, the first triangle in the figure is a 30°-60°-90° triangle.

Help!! Which inequality models the word sentence? A number reduced by 10 is more than 25. Question 2 options: m-10>25 m-10<25 m−10≤25 m−10≥25
Answer:
Option 4
Step-by-step explanation:
What is the intermediate step in the form (x + a)? = b as a result of completing the square for the following equation? x^2+39=-10x
The intermediate step in completing the square is to rewrite the equation in the form (x + 5)^2 = -14.
The intermediate step in completing the square for the equation x^2 + 39 = -10x is to rewrite the equation in the form (x + a)^2 = b.
To complete the square, we start by moving all the terms involving x to one side of the equation and leaving the constant term on the other side. In this case, we add 10x to both sides to get x^2 + 10x + 39 = 0.
Next, we divide the coefficient of x by 2 and square it. The coefficient of x is 10, so half of it is 5, and squaring it gives 25. We add this value to both sides of the equation, resulting in x^2 + 10x + 25 + 39 = 25.
Simplifying the equation further, we have (x + 5)^2 = -14.

2.) Four people are dealt 13 cards each. You (one of the
players) got one ace. What is the probability that your partner has
the other three aces?
The probability that your partner has the other three aces given that you have one ace is approximately 0.000037 or 0.0037%. This is a very low probability, so it is unlikely that your partner has the other three aces.
We can use Bayes' theorem to solve this problem. Let A be the event that your partner has the other three aces, and B be the event that you have one ace. Then we want to find P(A|B), the probability that your partner has the other three aces given that you have one ace.
Using Bayes' theorem, we have:
P(A|B) = P(B|A) * P(A) / P(B)
We know that P(B|A) is 1/3, since your partner must have all three aces if you have one ace. We also know that P(A) is the probability that your partner has all three aces in a randomly dealt hand of 39 cards (52 cards - 13 cards dealt to you), which is:
P(A) = (4/39) * (3/38) * (2/37) = 0.000038
To find P(B), the probability that you have one ace, we can use the law of total probability:
P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)
The probability that you have one ace given that your partner has all three aces is zero, so P(B|not A) is the probability of getting exactly one ace in a hand of 39 cards:
P(B|not A) = (4/39) * (35/38) * (34/37) * (33/36) * ... * (28/16) * (24/15) * (23/14) * (22/13) = 0.03833
where we multiply the probabilities of not getting an ace (35/38, 34/37, etc.) by the probability of getting an ace (4/36) for each card dealt after the first ace.
We also know that P(not A) is the complement of P(A), which is 1 - P(A).
Putting it all together, we have:
P(A|B) = (1/3) * (0.000038) / [ (1/3) * (0.000038) + (2/3) * (0.03833) ]
Simplifying, we get:
P(A|B) = 0.000037
So the probability that your partner has the other three aces given that you have one ace is approximately 0.000037 or 0.0037%. This is a very low probability, so it is unlikely that your partner has the other three aces.

g what is the difference between type 1 and type 2 errors in hypothesis testing? how do a and b relate to type 1 and type 2 errors?
In hypothesis testing, a Type 1 error occurs when we reject a null hypothesis that's actually true. In other words, we conclude that there's a significant effect or difference when there is not one. The probability of making a Type 1 error is denoted by the symbol alpha( α).
A Type 2 error, on the other hand, occurs when we fail to reject a null hypothesis that's actually false. In other words, we conclude that there's no significant effect or difference when there actually is one. The probability of making a Type 2 error is denoted by the symbol beta( β).
In general, Type 1 errors are considered more serious than Type 2 errors because they lead to false positive results and can have negative consequences, similar as making incorrect opinions or wasting coffers. still, the inflexibility of the consequences depends on the specific situation.
The chances of Type 1 and Type 2 errors are related to the significance position( α) and the power( 1- β) of the hypothesis test, independently. The significance position( α) is the probability of making a Type 1 error and is generally set at 0.05 or 0.01. .

It is estimated that 70% of a grapefruit crop is good; the other 30 % have rotten centers that cannot be detected until the grapefruit are cut open. The grapefruit are sold in sacks of 10. Let r be the number of good grapefruit in a sack. a.) What is the probability of getting no more than one bad grapefruit in a sack? b.) What is the expected number of good grapefruit in a sack? c.) What is the standard deviation of the r-probability distribution?
a) The probability of getting no more than one bad grapefruit in a sack can be calculated by adding the probabilities of getting zero bad grapefruit and one bad grapefruit. The probability of zero bad grapefruit is 0.7^10, and the probability of one bad grapefruit is (10C1) * 0.3 * 0.7^9. Adding these probabilities gives the desired result.
b) The expected number of good grapefruit in a sack is obtained by multiplying the number of grapefruit in a sack (10) by the probability of each grapefruit being good (0.7), resulting in an expected value of 7.
c) The standard deviation of the r-probability distribution is calculated using the formula sqrt(n * p * (1 - p)), where n is the number of grapefruit in a sack (10), and p is the probability of success (0.7). The standard deviation is approximately 1.449.
