the probabilities that amy and tess will arrive at party on time are 2/3 and 3/4 respectively. Find the probability that a. amy will arrive on time while tess is not
Answer:
1/6
Step-by-step explanation:
Probability that any arrives on time = 2/3
Probability that teaa arrives on time = 3/4
Probability that teas will not arrive in time = 1 - P(tess arrives on time) = 1 - 3/4 = 1/4
Hence,
The probability that Amy arrives in time and tess does not equals
2/3 * 1/4 = (2*1) / (3*4) = 2 / 12 = 1/6
Using it's concept, it is found that there is a 0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
The probability that Amy arrives on time is of 2/3.The probability that Tess does not arrive on time is of 1/4.Since they are independent, we multiply them, hence:
[tex]P = \frac{2}{3} \times \frac{1}{4} = \frac{2}{12} = 0.1667[/tex]
0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.

Frank turns his steering wheel a full circle of 360°. Which statement best represents the
movement of the steering wheel?
A. The wheel makes 260 one-degree turns.
B. The wheel makes 360 ten-degree turns.
C. The wheel makes 360 one-degree turns.
D. The wheel makes 360 one hundred-degree turns. (I can NOT go in websites to get the answer and pls give a example on how you did the problem. Thank you)
Answer:
C. The wheel makes 360 one-degree turns.
Step-by-step explanation:
A full circle is 360°, that is, there are 360 degrees in a circle.
You can check how many total degrees the steering wheel is turned for each option by multiplying the number of turns by the number of degrees for each turn:
For A: 260 one-degree turns is (260 turns) × (1 degree per turn) = 260 degrees turned. This is not equal to the given fact that Frank turns a full circle of 360 degrees. So A is not correct.For B: 360 ten-degree turns means a total of (360 turns) × (10 degrees per turn) = 3600 degrees turned, which does not equal one turn of 360 degrees. So B is not correct.For C: 360 one-degree turns means a total of (360 turns) × (1 degree per turn) = 360 degrees turned, which is one full circle.For D: 360 one-hundred degree turns means a total of (360 turns) × (100 degrees per turn) = 36000 degrees turned, which is not 360 degrees. So D is not correct.Kevin wants a new paddle board and will buy a package consisting of a board, custom fin, and paddle.

a vacuum had been marked down by 20% and solf for $250. What was the original price of the vacuum?
Answer:
The original price was $312.50
Step-by-step explanation:
If the vacuum was marked down by 20%, that means it was sold for 80% of the full price. It was sold for $250, so 80% of the original price is $250.
Let's set up an equation.
80/100 of x = 250
0.8 • x = 250
Divide both sides by 0.8.
x = 312.50
The original price was $312.50
Hope this helps!
Answer:
I think the answer is 250.00
Step-by-step explanation:
Let the original price = x
Original Price - Markdown = Sales Price
x - (20%)x = $250
Note: 20% may be 0.20 or 20/100 as needed by the problem.
x - 0.20x = $250
0.80x = $250
x = $312.50
Check:
Is 312.50 - (0.20)312.50 = 250.00 ?
(0.80)(312.50) = 250.00 ?
250.00 = 250.00 ?yes
Hope this help you! :)

int) A group of 10 hunters wait for ducks to fly by. When a flock of ducks flies overhead, the hunters all fire at the same time, each selecting a target at random and independently of the others. If each hunter independently hits his target with probability 0.4, and if all misses do not hit other ducks, what is the expected number of ducks that will be hit
Answer:
The expected number of ducks that will be hit is 4.
Step-by-step explanation:
For each hunter, there are only two possible outcomes. Either they hit a duck, or they do not. The probability of a hunter hitting a ducks is independent of any other hunter. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
A group of 10 hunters wait for ducks to fly by.
This means that [tex]n = 10[/tex]
Each hunter independently hits his target with probability 0.4
This means that [tex]p = 0.4[/tex]
What is the expected number of ducks that will be hit?
[tex]E(X) = np = 10*0.4 = 4[/tex]
The expected number of ducks that will be hit is 4.
How to solve (x+7)(x-9)>0
Answer:
x < -7, x > 9.
Step-by-step explanation:
Solve for x.
x = -7, 9
From the values of x above, we have these 3 intervals to test.
[tex]x < - 7[/tex]
[tex] - 7 <x < 9[/tex]
[tex]x > 9[/tex]
Pick a test point for each interval.
For the interval x < −7:
Let's pick x=−8. Then, (-8 + 7) (-8 - 9) > 0.
After simplifying, we get 17>0, which is true
Keep this interval.
Let's pick x=0. Then, (0+7)(0-9) > 0.
After simplifying, we get −63 > 0, which is false.
Drop this interval.
For the interval x > 9:
Let's pick x=10. Then, (10+7)(10-9)>0.
After simplifying, we get 17 > 0, which is true
Keep this interval.
Therefor, the answer is x < -7, x > 9.

So, you have 64 cups in 4 gallons.
ill mark you but i just wanna see if my answer is correct or not
Answer:
No, it should be 10.
Step-by-step explanation:
The first digit of 4 underlined in 448,023 represents 400,000.
As 448,023 =
(400,000) + (40,000) + (8,000) + (20) + (3).
While the second digit of 4 that is not underlined in 448,023 represents 40,000.
400,000 / 40,000 = 10.
independent compound event definition
Answer:
Independent events occur when the outcome of one event does not affect the outcome of the second event. Rolling a four has no effect on tossing a head. To find the probability of two independent events, multiply the probability of the first event by the probability of the second event.
Other answer:
A compound event is the combination of two or more simple events (with two or more outcomes). Compound Probabilities (with more than one outcome (desired result) within a trial ): • The probability of rolling an even number less than 5 on a die. (

x = 50
Step-by-step explanation:
The sum of exterior angles of a convex polygon is 360°.
130° + x° + 30° + 100° + x° = 360°
2x° = 100° . . . . . . . . . subtract 260° and collect terms
x = 50 . . . . . . . . divide by 2°

Additional comment
If you reduce each side length to nothing, then you find the angles are measured around a central point. It becomes more clear that their sum is 360°.

tan(3)=a/4960
Answer:
[tex]\boxed {\boxed {\sf 260 \ feet}}[/tex]
Step-by-step explanation:
We are asked to find the driver's altitude increase. The increase in altitude is also the height of the triangle, which is labeled a.
Since this is a right triangle (signified by the small square representing a 90 degree angle), we can use trigonometry. The three trigonometric ratios are:
sinθ=opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ=opposite/adjacentThe angle (θ) given is 3 degrees. Side a is opposite this angle and the side measuring 4,960 feet is the hypotenuse because it is opposite the right angle. Therefore, we use sine.
[tex]sin \theta= \frac {opposite}{hypotenuse}[/tex]
[tex]sin 3= \frac {a}{4960}[/tex]
We are solving for a, so we must isolate the variable. It is being divided by 4960 and the inverse of division is multiplication. Multiply both sides by 4960.
[tex]4960*sin 3= \frac {a}{4960}*4960[/tex]
[tex]4960*0.05233595624= a[/tex]
[tex]259.586343=a[/tex]
Round to the nearest whole number. The 5 in the tenth place tells us to round the 9 to a 0 in the ones place, then the 5 to a 6 in the tens place.
[tex]260 \approx a[/tex]
The driver's increase in altitude is approximately 260 feet.
