Answer:

29.5

Step-by-step explanation:

Order from least to greatest

11, 17, 17, 19, 28, 31, 40, 44, 45, 49

Then find the middle number which is 28 and 31 so add the two numbers

28 + 31 = 59

then

59 divided by 2 = 29.5

(Please answer it correctly please please show work )Thalia tosses a fair number cube with faces numbered 1 to 6. Which is a rea
anastassius [24]

Answer:40

Step-by-step explanation:

On a fair die, each face has a 1/6 chance of landing on each toss.

5 and 6 are the only faces greater than 4, therefore there is a 1/6 + 1/6 = 2/6 chance of the die landing on a number greater than 4 for each toss.

Multiply the probability by the total number of tosses to get the number of tosses that are greater than 4.

120 * (2/6) = 240/6 = 40

Approximately 40 tosses will land on a number greater than 4.

An object is thrown upward from the top of a building with an initial velocity of 48 feet per second. The height h of the object
Lubov Fominskaja [6]

Answer:

5 secs

Step-by-step explanation:

The height of the object is given as:

h = -16t^2+48t+160

The moment when the object hits the ground, the height of the object will be 0 m.

Hence:

0 = -16t^2+48t+160

Solving this for t:

Divide through by 16 and move all parameters to the left hand side:

t^2-3t-10 = 0

t^2 - 5t + 2t - 10 = 0\\\\\\t(t - 5) + 2(t - 5) = 0\\\\\\(t + 2)(t - 5) = 0\\\\\\=> t = -2, 5

Since time cannot be negative, time, t = 5 secs.

The object will hit the ground after 5 secs.

The smallest of the three circles with center D has a radius
otez555 [7]

Answer:

464 π in²

Step-by-step explanation:

The smallest circle has a radius of 8 in.

The middle circle has a radius of 8 + 4 = 12 in.

The largest circle has a radius of 12 + 4 = 16 in.

So the sum of the areas is:

π (8 in)² + π (12 in)² + π (16 in)²

= 64π in² + 144π in² + 256π in²

= 464π in²
