If you roll a fair number cube 30 times, what is the experimental probability of rolling a 2
Answers
Answer:
1/6 chance or 16.667% chance
Step-by-step explanation:
a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6
how do you find the fist step to solving the system of equations x+y=8 and 3x-2y=-6
Answers
Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6
the table shows the results of rolling a number cube labeled 1 through 6 30 times
based on the results, if the cube roles 200 times, how many times is it expected to land on 1
Answers
Answer:
40 times
Step-by-step explanation:
To figure this out, divide 6 by 30, then multiply by 200
(6/30)200 = 40
This also works: (200/30)6 = 40
We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.

Approximate square root 18 to the nearest hundredth. Be sure to show all of your work.
Answers
Answer:
The square root of 18 with one digit decimal accuracy is 4.2.
Step-by-step explanation:
Answer:
4.24 (nearest hundredth)
Step-by-step explanation:
Step 1
Square numbers: 1, 4, 9, 16, 25, 36, ...
Find the perfect squares either side of 18:
16 and 25As [tex]\sf \sqrt{16}=4[/tex] and [tex]\sf \sqrt{25}=5[/tex] then [tex]\sf 4 < \sqrt{18} < 5[/tex]
Step 2
Divide 18 by one of the two square roots in step 1 (4 or 5):
⇒ 18 ÷ 4 = 4.5
Step 3
Find the average of the root (4) and the result (4.5):
[tex]\sf \implies \dfrac{4+4.5}{2}=4.25[/tex]
Repeat steps 2 and 3:
Divide 18 by the solution of step 3. Then find the average of this and the solution of step 3:
⇒ 18 ÷ 4.25 = 72/17
[tex]\sf \implies \dfrac{4.25+\frac{72}{17}}{2}=\dfrac{577}{136}=4.242647059[/tex]
Repeat:
⇒ 18 ÷ 577/136 = 2448/577
[tex]\sf \implies \dfrac{\frac{577}{136}+\frac{2448}{577}}{2}=4.242640687[/tex]
As the approximate square root needs to be to the nearest hundredth, we do not need to keep repeating the steps.
Therefore, √18 ≈ 4.24 (nearest hundredth)

Answers
Answer:
Step-by-step explanation:
The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
How to solve the decimals?
From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.
In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.
Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

At noon, a team bus left City College for their opponent's school. Soon thereafter, City's first-line player Brett Starr arrived at the gym. A loyal day-student parent volunteered to overtake the bus and deliver Brett. The two left at 12:15 pm. The parent drove at 54 mph, while ahead of them the yellow bus poked along at 48 mph. Did the car catch the bus before it reached the game, which is 110 miles from City college? If so, where and when?
Answers
Answer:
No, the car didn't catch the bus, as their time and distance traveled doesn't intersect when portrayed on a graph.
Step-by-step explanation:
It would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.
What is the average speed?Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.
Yes, the car was able to catch up to the bus before it reached the game. With the car travelling at 54 mph and the bus travelling at 48 mph, the car is travelling 6 mph faster than the bus. In order to calculate how long it would take for the car to catch the bus, we use the formula for average speed:
Average speed = (speed of car + speed of bus) / 2
Average speed = (54 mph + 48 mph) / 2
Average speed = 51 mph
Now, we can use the formula for distance travelled over time to calculate how long it would take the car to travel the 110 miles to the game:
Distance = Rate x Time
110 miles = 51 mph x Time
Time = 110 miles / 51 mph
Time = 2.14 hours
Therefore, it would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.
