Answer:

Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.

Step-by-step explanation:

Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.

Step-by-step explanation:

I hope I helped, and I always appreciate brainliest!!!  :)

The solution of the equation is x = 2 .

Given,

Equation : 5x=2x+6

Here,

Algebraically solving the equation :

5x=2x+6

Take 2x from RHS to LHS .

5x - 2x = 6

3x = 6

Now divide both sides by 3 .

x = 6/3

x = 2

Thus the value of x is 2 .

The graph will be a straight line at x=2 .

Add all the fractions greater than 1/4 inches

The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.

Since the equivalent to 1 by 4 should be like  2/8, 3/12, 4/16 etc. Here the fractions that come after 1 by 4 so it should be more than 1 by 4. So now we have to determine the count and also the x in the column for the measurements so based on this, we can get 6.

Therefore, The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.

Answer:

51700

Step-by-step explanation:

So basically you take the last  three numbers. the middle 6 is over 5 so you round the first 6 to 7 and the rule for that is 5 or above round up 4 or below round down  

51668 to the nearest hundred is 51700

1. Identify the hundreds digit of the number.

2. Identify the next smallest place value.

3. We have to find out,is that digit greater than or equal to five!

4. Increase the hundred digit by 1 if greater or equal to 5 & decrease if less than 5. And every digit after it, becomes zero.

Given number is 51668

Hundreds digit number is 6.

Next smallest place value is 6, which is greater than 5.

So, After increasing hundred digit by 1,The required number is 51700

(9,1 ) is the solution of  64(x-8)²+ 12y² < 144 inequality.

A solution for an inequality in x and y are numbers such that when we substitute that number for x and y we have a true statement.

We substitute x = 9 and y = 1 in each inequality. The inequality, for which the values satisfy, has (9, 1) as the solution.

1.

x² - y² > 84

81 - 1 > 84

80 > 84

not true.

2.

x >= 3(y+2)² - 2

9 >= 3(3)² - 2

9 >= 27 - 2

9 >= 25

not true.

3.

4(x-4)² - 16(y+1)² > 36

4(5)² - 16(2)² > 36

100 - 64 > 36

36 > 36

not true.

4.

64(x-8)² + 12y² < 144

64 + 12 < 144

76 < 144

True.

Hence, 64(x-8)²+ 12y² < 144 has the solution (9, 1).

Answer:

9

Step-by-step explanation:

because the shape is equal and 106 minus 97 is 9.

Answer:

9

Step-by-step explanation:

Those two angles should be equal to each other, so turn that into an equation.

106=x+97

Now solve for x

108-97 = 9

x=9

w = 12

to solve this, you have to multiply both sides by 2 to cancel out the two on the left. you’ll be left with -7w = 84. then, you divide both sides by -7 to isolate the variable, which is w. you’ll end up with w=12.

Answer:

Step-by-step explanation:

(x +y)² = x² + 2xy +y²

-5(x + 3)² = -80

-5(x² + 2*x*3 + 3²) = -80          

-5(x² + 6x + 9) = -80

Divide the equation by (-5)

x² + 6x +9 = -80/-5

x² + 6x + 9 = 16

x² + 6x + 9 - 16 = 0

x² + 6x  - 7 = 0

x² - x + 7x - 7 = 0

x(x - 1)  + 7(x - 1) = 0

(x - 1)(x + 7) = 0

x -1 = 0   ; x + 7 = 0

x = 1     ; x = -7

Answer: Pythagorean Theorem in 3 D

sqrt ( 3^2 + 4^2 + 2^2) =

sqrt ( 9 + 16 + 4) =

sqrt( 29) = 5.3852 approximately

Step-by-step explanation:

The longest diagonal is about 8.9 inches. The longest length is going to be between the two longest lengths, the width and the height. The Pythagorean theorem is a^2 + b^2 = c^2. Plug the width and height into a and b of the Pythagorean equation. (4)^2 + (8)^2 = c^2. Now simplify the equation. 16 + 64 = c^2. 80 = c^2. Now find the square root of each side. (sqrt)80 = (sqrt)c^2. If you simplify this, you will find that c is equal to about 8.9 inches.
