A consumer group is investigating the number of flights at a certain airline that are overbooked. They conducted a simulation to estimate the probability of overbooked flights in the next 5 flights. The results of 1,000 trials are shown in the following histogram.
Answer:
C. 0.446
Step-by-step explanation:
1-(0.114+0.332) = 0.446
The sum of the relative frequencies of the bars for 4 and 5 is 0.446.
The probability that atleast four of the next five flights will be overbooked is the sum of the probabilities of having 4 or 5 flights overbooked which is 0.446
The probability of having atleast 4 flights overbooked can be defined as :
P(X ≥ 5) = P(X = 4) + P(X = 5)
From the probability distribution displayed on the histogram :
P(X ≥ 5) = 0.332 + 0.114 = 0.446
Therefore, the probability of having atleast 4 flights overbooked ls 0.446

The given triangle satisfies the Pythagoreans theorem, therefore it is a right angle triangle.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or and it follows Pythagoreans theorem.
Given that,
Sides of triangles are 156cm, 133cm and 205cm
To verify, this triangle is a right angle triangle,
Use Pythagorean formula,
Sum of square of two sides = third Side
(156)²+(133)²= 24336+17689
= 42025
(205)² = 42025
Here, (156)²+(133)² = (205)²
This implies that, the given triangle is a right angle triangle.

Answer:
time greater than 6 hours
Step-by-step explanation:
For this problem, we are given the rate at which the refrigerator's temperature increases and the rate at which the oven's temperature decreases along with the initial temperatures for both. Using this information, we can determine the amount of time that will need to pass for the two to have equal temperature, or pass each other in opposite directions of temperature. Let's write the inequality using the information:
40 + 5t > 340 - 45t
Let t be the amount of time passed in hours. So, we simply need to solve the inequality for t.
40 + 5t > 340 - 45t
40 + 50t > 340
50t > 300
t > 6
Given this information, we know that after 6 hours have passed, the temperature of the fridge and oven will be equal. So we can say that any time greater than 6 hours, the fridge will have a higher temperature than the oven.

Answer:
x = 73
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define equation
(180 - x) + (90 - x) = 124
Step 2: Solve for x
Combine like terms: 270 - 2x = 124Subtract 270 on both sides: -2x = -146Divide -2 on both sides: x = 73Step 3: Check
Plug in x to verify it's a solution.
Substitute: (180 - 73) + (90 - 73) = 124Subtract: 107 + 17 = 124Add: 124 = 124The original price of a scarf is $16. During a store-closing sale, a shopper saved $12 on the scarf. What percentage discount did she receive?

Answer:
its bc 3x226 is 678 2x339 is 678 and 6 x 113 is 678
Step-by-step explanation:MARK BRAINLIEST I NEED 1 MORE
Using the divisibility rules, 678 is divisible by 2, 3, and 6.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need ot find that 678 is divisible by 2, 3, and 6.
WE can see 678 is even, so it's divisible by 2
Now, the sum of digits are 6+7+8 = 21, which is divisible by 3, so 678 is divisible by 3
Since 678 is divisible by both 2 and 3, then it has to be divisible by 6
Using the divisibility rules, we can conclude that 678 is divisible by 2, 3, and 6.

From the figure below if J is the center △ SUZ
Then SJ = .....
help!!!
Answer:
[tex] SJ = 6 [/tex]
Step-by-step explanation:
Given that J is the center of the ∆SUZ, therefore, J is the centroid of the ∆.
According to the centroid theorem, thus:
Centroid J will divide VS into VJ and SJ into the ratio of 1 : 2.
This means, SJ is twice the length of VJ.
Therefore, given that VJ = 3, thus:
SJ = 2(3) = 6.
SJ = 6 units.

Rodney wants to buy a camera that costs $133. This amount is $25 more than 3 times the amount he saved last month. Which equation could be used to solve for x, the amount Rodney saved last month?
Answer: 25+3x =133
Step-by-step explanation:
Let x = the amount Rodney saved last month
Cost of camera Rodney wants to buy= $133 , which is $25 more than 3 times the amount he saved last month.
i.e. 25+3(amount Rodney saved last month) = Cost of camera (in dollars)
i.e. 25+3x =133 (in dollars)
Hence, the equation could be used to solve for x : 25+3x =133
