The experimental probability of getting a 6 on a number cube is StartFraction 7 over 40 EndFraction. Which is true about the event’s experimental probability? The number 6 came up a total of 40 times. The number 6 came up 7 times out of a total of 40 trials. The number cube was rolled a total of 47 times. After 7 trials, the number 6 came up 40 times.
Answer:
The number 6 came up 7 times out of a total of 40 trials.
Step-by-step explanation:
took the test
The correct option is the number 6 came up 7 times out of a total of 40 trials.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Event: getting a 6 on a number cube
P( getting a 6 on a number cube) = 7/40
So, to expand the meaning of given probability we have
The number 6 came up 7 times out of a total of 40 trials.

If a person was randomly selected, what is the probability that the person selected rock climbing given that the person is female?
Answer:80 % chance
Step-by-step explanation:
The required probability that the person selected rock climbing given that the person is female is 23%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
As mentioned in the question,
Total person in the adventure sports = 100
female rock climbers = 23
The probability that the person selected rock climbing given that the person is female is given as,
= female rock climbers / Total person in the adventure sports
= 23/ 100
= 0.23
Thus, the probability that the person selected rock climbing given that the person is female is 23%.

Answer:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Step-by-step explanation:
The distance between two points A(x₁,y₁) B(x₂,y₂) is given by the formula as follows :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is used to find the distance between two points. It is an application of the Pythagorean theorem. Usually, the distance covered is equal to the product of speed and time. But when speed and time in not given but coordinates are given, then only we can use this formula.

Which situation could the expression −255 represent? A Each of 5 golfers has the same score after 9 holes. The total of their scores is -25. So, each golfer's score is -5.Each of 5 golfers has the same score after 9 holes. The total of their scores is -25. So, each golfer's score is -5. B A temperature increases 25°F over 5 hours. So the temperature increased by 5°F per hour.A temperature increases 25degreeF over 5 hours. So the temperature increased by 5degreeF per hour. C A football team gains 25 yards in one play. They lose 5 yards in the next play. In the two plays combined, the team gained 5 yards.A football team gains 25 yards in one play. They lose 5 yards in the next play. In the two plays combined, the team gained 5 yards. D Over 5 weeks, Alyson withdraws $25 per week from her checking account. Altogether, she withdraws $125.
Answer and explanation:
Not sure if the question is complete or valid but I will explain each option:
Let's assume the question asks which of the options would provide a negative result of -25( as no option evaluates to -255)
A. There would be a negative result here since all golfers have a negative score of -5 after 9 holes, and therefore a total score of -25 for all five golfers
B. Temperature increases by 25 degrees after 5 hours hence 5 degrees increase for every 1 hour. This would obviously give a positive result.
C. A football team gains 25 yards in the first play and loses 5 yards in the second but has a result of 5 yards gained in total. Hence there was a penalty of losing 20 yards for a loss of 5 yards= 25 yards- 20 yards= 5yards
D. Alyson withdraws $25 every week for 5 weeks, therefore she withdraws $125 in 5 weeks. This would be a negative result of -$125.

Juan wants to solve the equation below using the Distributive Property.4(6 – x) = 12What should Juan’s first step be?
A.Multiply 4 by x.
B.Subtract x from 6.
C.Distribute 4 to (6 – x).
D.Subtract 4 from both sides.
Answer:
C
Step-by-step explanation:
Juan's first step to solve the distributive property will be to distribute 4 to (6 – x). The correct option is C.
What is distributive property?This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
Given that Juan wants to solve the equation below using the Distributive Property 4(6 – x) = 12.
The equation can be solved as:-
4(6 – x) = 12
24 - 4x = 12
4x = 36
x = 9
Hence, the value of x is 9 when the equation is solved by distribution.

Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-2(x - 4) = -16
Step 2: Solve for x
Distribute -2: -2x + 8 = -16Isolate x term: -2x = -24Isolate x: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: -2(12 - 4) = -16Subtract: -2(8) = -16Multiply: -16 = -16Here we see that -16 does indeed equal -16.
∴ x = 12 is a solution of the equation.
The melting points of some chemical elements are shown below. Nickel: 2,651 Mercury: -37.89 Helium: -458 Copper: 1,984.32 a) Which two elements have melting points that are closest in value? b) What is the average melting point of the substances? Round your answer to the nearest tenth. Explain how you got to the answer.
Answer:
Mercury and helium
1034.8575
Step-by-step explanation:
Given that :
Melting point of substances :
Nickel: 2,651
Mercury: -37.89
Helium: -458
Copper: 1,984.32
Melting means change of solid to liquid
a) Which two elements have melting points that are closest in value?
The difference in Melting point between mercury and helium :
- 37.89 - (-458) = 420.11
Nickel and copper :
2651 - 1,984.32 = 666.68
Hence, element with melting point which are closest in value Are Mercury and helium
b) What is the average melting point of the substances?
Sum of the melting points / number of substances
(2,651 + (-37.89) + (-458) + 1,984.32) / 4
= 4139.43 / 4
= 1034.8575
