-4>-6
Step-by-step explanation:
come on dude
Each spin consists in a choice of a number among 1, 3, 4 and 6. This means that there are two odd numbers and two even numbers.
You get an even number if you sum two numbers with the same parity, you get an odd number if you sum two numbers with opposite parity.
Whatever number you get from the first spin, you have a 50% chance of spinning a number with the same parity with the second spin, and a 50% chance of spinning a number with opposite parity with the second spin.
So, with each turn, you have a 50% chance of getting an even sum, and a 50% chance of getting an odd sum.
This means that, by definition, the expected number of spaces moved is
So, on average, you move 2 steps foward.
Answer:
110 ft³ of water
Step-by-step explanation:
Use the prism volume formula, V = Bh, where B is the area of the base and h is the height.
Plug in the area of the base and height, and solve for V:
V = Bh
V = (22)(5)
V = 110
So, the volume is 110 ft³
There is 110 ft³ of water in the tank
Answer:
2
Step-by-step explanation:
because it goes through the y axis and in the equation y=12×+2 is like y=m×+ b which means b or 2 is the y intercept
Answer:
26.59 minutes
Step-by-step explanation:
Let's say the time needed to do the driveway combined is x. Sue does y parts of the driveway, and Tom does z parts of the driveway. Combined, y + z = 100% = 1, as they finish the whole driveway.
Next, Tom will take 45 * z minutes to do his part of the driveway. For example, if he did 50% = 0.5 of the driveway, he would take 45 * 0.5 = 22.5 minutes to do it. Similarly, Sue will take 65 *y minutes to do her part of the driveway. Since they will finish at the same time, we can say
45 * z = 65 * y
y + z = 1
Therefore, if we subtract y from both sides of the second equation, we have
z = 1-y
We can then plug 1-y in for z in the first equation to get
45 * (1-y) = 65 * y
45 - 45*y = 65*y
add both sides by 45 * y to separate the y values and their coefficients
45 = 110 * y
divide both sides by 110 to find y
y = 45/110 = 0.409
Use 1-y=z to get z = 1-0.409 = 0.59
Therefore, 45*z = 26.59 = 65*y
