Step-by-step explanation:

The probability that he selected the special quarter is 87.5%.

Given that Mandvil has one standard quarter and one special quarter with a Head on both sides, and he selects one of these two coins at random, and without looking at it first, he flips the coin three times, to determine, if he flips a Head three straight times, what is the probability that he selected the special quarter, the following calculation must be made:

Therefore, the probability that he selected the special quarter is 87.5%.

Check the picture below.

we can simply get the volume of the larger sphere, then the volume of the smaller sphere and subtract it from that of the larger sphere and what's leftover is the region between both.

[tex]\stackrel{\textit{\large volumes}}{\stackrel{\textit{sphere with r=6}}{\cfrac{4\pi (6)^3}{3}}~~ -~~\stackrel{\textit{sphere with r = 3}}{\cfrac{4\pi (3)^3}{3}}}\implies 288\pi -36\pi \implies 252\pi \approx \stackrel{cubic~units}{791.68}[/tex]

The region within the larger sphere and not within the smaller sphere is 789.02 cubic units.

The volume of sphere is the measure of space that can be occupied by a sphere.  If the radius of the sphere formed is r and the volume of the sphere is V. Then, the volume of the sphere is given by: Volume of Sphere, V = (4/3)πr³

Given that, there are two concentric spheres of radii 3 units and 6 units.

Now,

Volume of sphere with radius 3 units is

V₁ = 4/3×3.14×3³

= 4/3×3.14×27

= 4×3.14×9

= 113.04 cubic units

Volume of sphere with radius 6 units is

V₂ = 4/3×3.14×6³

= 4/3×3.14×216

= 902.06 cubic units

Now, difference is 902.06-113.04

= 789.02 cubic units

Therefore, the region within the larger sphere and not within the smaller sphere is 789.02 cubic units.

Answer:

x = cd-by/ a

Step-by-step explanation:

ax + by / c = d

ax + by = cd

ax = cd-by

x = cd-by/a

Answer:

B

Step-by-step explanation:

You can multiply both sides by c to remove the fraction part.

d(c) = ax + by/c(c)

dc = ax + by

Then subtract "by" from both sides to isolate x.

dc - by = ax - by + by

dc - by = ax

Then divide both sides by a to completely isolate the variable x.

(dc - by)/a = ax/a

(dc - by)/a = x

B

Answer:

Our inequality is 8 < x < 10, where x is our number.

Since the problem doesn't specify whether the number x is an integer or not, we can assume that x can be either a decimal or a whole number. That means that we want any decimal number or whole number between 8 and 10. The only whole number is 9, but there are infinitely many decimal solutions. For example, we could have 8.001, 8.0001, 8.00001, etc.

Thus the answer is D.

Answer:

  100

Step-by-step explanation:

We assume that you are concerned with integers, and that you only count a number as "3-digit" if it does not have a zero in the hundreds place.

In order for the number to have a minimum value, the minimum available digit must be used in each number place, starting from the most-significant place--the hundreds place.

The least (non-zero digit) available for the hundreds place is 1.

The least digit available for the tens place is 0.

The least digit available for the ones place is also 0, since it is allowed to duplicate a digit already used.

The least possible 3-digit number using 2 different digits is 100.

The inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10

Since Dante has 20 goldfish and gives out 2 goldfish every month,

After one month, he has 20 - 2 = 20 - 1(2) gold fish left.

After 2 months, he has 20 - 2 - 2 = 20 - 4 = 20 - 2(2) goldfish left.

After 3 months, he has 20 - 2 - 2 - 2 = 20 - 6 = 20 - 3(2) goldfish left.

So, after m months, he has 20 - 2m goldfish left.

For the number of goldfish to be less than 10, we have the inequality

20 - 2m < 10

So, the inequality that can be used to find m, the number of months after receiving his fish tank, when Dante will have less than 10 goldfish in his fish tank is 20 - 2m < 10

Answer:

See below

Step-by-step explanation:

To find the mean, you take each data point, add them together, and divide it by the number of data points.

Problem 1

Mean of High Temperatures = (65+67+54+52+63+69+75)/7 = 445/7 = between 63 and 64

Problem 2

Mean of Low Temperatures = (61+55+37+29+34+42+54)/7 = 312/7 = between 44 and 45

The answer is 6000 degrees per second.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: The propeller rotate4s 1000 times per minute. That means that the propeller rotates 1000 / 60 times per second.

That's 16 and 2/3 revolutions in 1 second.

16 * 360 = 5760 degrees.

2/3 * 360 = 240 degrees.

Total number of degrees is equal to 5760 + 240 = 6000 degrees per second.

Hence, The  propeller rotates 6000 degrees per second.
