For what value of 0 does sin20 = cos (0 +30)?

The given inequality is true when w is greater than 5: w > 5. (option 4)

To solve the inequality, we can simplify the expression inside the absolute value brackets by distributing the negative sign and combining like terms:

Now we can split the inequality into two cases: 14w - 2 > 7 and -(14w - 2) > 7. Solving each case for w gives:

14w - 2 > 7

14w > 9

w > 9/14

-(14w - 2) > 7

-14w + 2 > 7

-14w > 5

w < -5/14

So the solution to the inequality is w > 9/14 or w < -5/14. However, we are given that w is greater than 5, so the only valid solution is w > 5.

To show that p(your winning) <1/2, we need to consider that the last piece you have on your board could land on various positions. Depending on the position, your opponent could end up winning even if you land a higher value on the dice. Therefore, the probability of your winning is less than 1/2. This shows that a double is not called for.Exercise 3.1 states that the expected count on a backgammon roll is 8 6 1, exceeding the 8 points you need to win. This is true since the expected count means the average count you are expected to land on if you roll the dice. It does not mean that every roll will result in a count higher than 8, and it does not mean that you will always win. The expected count is simply a statistical measure of the possible outcomes of rolling the dice. Therefore, this result does not contradict the fact that p(your winning) <1/2.

99*101=(100-1)(100+1)

let's use short mltiplication formula,

If there is a 5% chance that none of the items on a scratch-off lottery ticket will be a winner, the probability that at least one of the scratch-off items will win is 95%.

If there is a 5% chance that none of the items on a scratch-off lottery ticket will be a winner, then the probability of winning on any one item is 1 - 0.05 = 0.95 (i.e., a 95% chance of winning on any one item).

The complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring, can be used to determine the likelihood that at least one of the scratch-off items will win. In this case, the event we are interested in is winning on at least one item. The complement of this event is not winning on any item.

So, the probability of winning on at least one item is:

1 - 0.05 = 0.95

Therefore, there is a 95% chance that at least one of the items on a scratch-off lottery ticket will win.

To graph the vertices of the quadrilateral ABCD, we need to use a graphing calculator to find the sides and then the area can be calculated as;

We can use the Shoelace Formula to find the area of the quadrilateral. The Shoelace Formula is based on the idea of using the coordinates of the vertices of the polygon to calculate its area.

The formula is:

Area = 1/2 * |(x1y2 + x2y3 + ... + xny1) - (y1x2 + y2x3 + ... + ynx1)|

where (x1,y1), (x2,y2), ..., (xn,yn) are the coordinates of the vertices of the polygon in order, either clockwise or counterclockwise.

Using this formula, we get:

Area = 1/2 * |(13 + 2(-3) + 01 + (-3)4) - (42 + 30 + (-3)(-3) + 11)|

Area = 1/2 * |(-3 - 6 - 12 - 12) - (8 + 0 + 9 + 1)|

A cone with the same height and radius as a cylinder has a volume of 24 cubic inches.

If a cylinder has a volume of 72 cubic inches, we can use the formula for the volume of a cylinder to find its height and radius. The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, and h is the height.

So, we have:

72 = πr^2h

We can solve this equation for h:

h = 72/(πr^2)

Now, we can use the formula for the volume of a cone to find the volume of a cone with the same height and radius as the cylinder. The formula for the volume of a cone is V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.

So, we have:

V = (1/3)πr^2(72/(πr^2))

Simplifying this equation, we get:

V = 24

The rate of decrease of volume of the sphere when its diameter is 6 cm is -96π cubic cm/min.

Given that the snowball is a sphere, we can use the formula for the volume of a sphere.

The formula for the volume of a sphere is

V = 4/3 πr³

We need to find out the rate of decrease of volume when the diameter is 6 cm.

To find the rate of decrease of volume, we need to differentiate the above formula. Differentiating the above formula w.r.t. time, we get

dV/dt = 4/3 π(3r²)(dr/dt)

Where r is the radius of the sphere and dr/dt is the rate of change of the radius.

Let d be the diameter of the sphere. Then we can write,r = d/2

Also, given that dr/dt = -2cm/min

Substituting the values in the equation for the rate of decrease of volume,

dV/dt = 4/3 π(3(d/2)²)(-2) = -8π/3 d²

As the diameter of the sphere is 6 cm, d = 6 cm.Substituting the value in the equation above, we get

To find out how many sixth grade textbooks were used, divide 57.1 cm by the height of one sixth grade textbook. Then multiply that number by 23 to get the total number of sixth grade textbooks used.

If you want to find out how many sixth grade textbooks were used for the tower, you first have to calculate the height of one sixth grade textbook. Once you have that measurement, you can divide 57.1 cm by that height to get the number of sixth grade textbooks used in the tower. To get the total number of textbooks used, you then need to multiply the number of textbooks per tower by 23, since 23 fifth grade textbooks were used. In other words, if the height of one sixth grade textbook is h, the number of sixth grade textbooks used is (57.1 cm / h) * 23.

Answer:

343 cubic meters.

Step-by-step explanation:

To find the volume of a cube given its surface area, we need to first find the length of one of its sides.

The formula for the surface area of a cube is:

SA = 6s^2

where SA is the surface area and s is the length of one of the cube's sides.

We are given that the surface area is 294 square meters, so we can set up the equation:

294 = 6s^2

Simplifying, we get:

49 = s^2

Taking the square root of both sides, we get:

s = 7

So the length of one of the cube's sides is 7 meters.

To find the volume of the cube, we use the formula:

V = s^3

Substituting in 7 for s, we get:

V = 7^3 = 343

Therefore, the volume of the cube is 343 cubic meters.

Answer:

343m³

Step-by-step explanation:

Surface area of a cube is A = 6a²

6a² = 294

Divide both sides by 6

a² = 49

Square root of both sides

a =7

Substitute the value of a into volume

Volume of Cube V = a³

P(x=3) = (4 chοοse 3) [tex]* 0.35^3 * 0.65^1 = 0.1124[/tex]

P(x=4) = (4 chοοse 4) [tex]* 0.35^4 * 0.65^0 = 0.0118[/tex]

When we rοund these numbers tο fοur decimal places, we get:
