The true conclusion about the cube are :

This is a perfect cube

The side length is 9 centimeters

Taking the cube root of the volume will determine the side length.

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes.

Volume of a cube = l³

where

l = length

Therefore,

volume = l³

729 = l³

cube root both sides

l = ∛729

l = 9 cm

Therefore, what is true about the cube is as follows:

This is a perfect cube

The side length is 9 centimeters

Taking the cube root of the volume will determine the side length.

Answer:

$8.22

Step-by-step explanation:

Items purchased :

Banana = 3 pounds

Price per pound of banana = $0.69

Cost of 3 pounds of banana = (3 * 0.69) = $2.07

Apple = 5 pounds

Price per pound of apple = $1.23

Cost of 5 pounds of apple = (5 * 1.23) = $6.15

Total cost :

$(2.07 + 6.15) = $8.22

Step-by-step explanation:

The possible outcomes are :

1,2,3,4,5,6

We can see that there is a 3/6 (or 1/2) chance the outcome is even

Let E= odds of getting an even

we're looking for E∩E

Because each roll is independent of the last we can multiply to find their intersection

Answer:

c. 25°

Step-by-step explanation:

Sum of angles in a triangle:

The sum of the measures of the angles of a triangle is 180º.

In this question:

Angles of 3x, 2x-13 and 5x + 3.

The sum is 180º. So

[tex]3x + 2x - 13 + 5x + 3 = 180[/tex]

[tex]10x - 10 = 180[/tex]

[tex]10x = 190[/tex]

[tex]x = \frac{190}{10}[/tex]

[tex]x = 19[/tex]

Measure of each angle:

3x = 3(19) = 57º

2x - 13 = 2(19) - 13 = 38 - 13 = 25º

5x + 13 = 5(19) + 3 = 95 + 3 = 98º

The smallest angle is 25º, and the correct answer is given by option c.

Answer:

44°

Step-by-step explanation:

From sin rule:

a / sin A = b / sin B = c / Sin C

3.6 / sin b = 5.1 / sin 100

Cross multiply :

5.1 * sinb = 3.6 * sin 100

Sin b = 3.5453079 / 5.1

Sin b = 0.6951584

b = sin^-1(0.6951584)

b = 44.039

b = 44°

Answer:

[tex](a)\ \sin(46) = \frac{8}{RT}[/tex]

[tex](b)\ RT = 11.1[/tex]

Step-by-step explanation:

Given

The attached triangle

Solving (a): Equation to determine RT

To do this, we apply sine formula

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

This gives:

[tex]\sin(46) = \frac{8}{RT}[/tex]

Solving (b): Solve the equation

[tex]\sin(46) = \frac{8}{RT}[/tex]

Make RT the subject

[tex]RT = \frac{8}{\sin(46)}[/tex]

[tex]RT = \frac{8}{0.7193}[/tex]

[tex]RT = 11.1[/tex]

Answer:

c. 6.2 ± 2.626(0.21)

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 101 - 1 = 100

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 100 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.626

The confidence interval is:

[tex]\overline{x} \pm M[/tex]

In which [tex]\overline{x}[/tex] is the sample mean while M is the margin of error.

The distribution of the number of puppies born per litter was skewed left with a mean of 6.2 puppies born per litter.

This means that [tex]\overline{x} = 6.2[/tex]

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.626\frac{2.1}{\sqrt{101}} = 2.626(0.21)[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

Thus, the confidence interval is:

[tex]\overline{x} \pm M = 6.2 \pm 2.626(0.21)[/tex]

And the correct answer is given by option c.

Answer:

Prob = 0.00009 = 0.009%  , Less Likely

Step-by-step explanation:

Using Binomial Distribution, Prob = N c r . ( P )^ r . ( Q ) ^ (n -r)   .

,P = success probability, ie candidate considered be trustworthy = 70% = 0.7; N = trials = 200 ; Q = failure probability, ie non trustworthy = 1 - 0.7 = 0.3  r = no. of success = 116

Pr = 200c116 . (0.7)^116 . (0.3)^(200 - 116) = 200c116 (0.7)^116 (0.3)^84 = 0.00009 = 0.009%

Less probability means Less Likely

Answer:

- 1 5/24 cm

Step-by-step explanation:

We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.

So - 1 1/3 = - 1 80/240 = 320/240

21/80 = 63/240

-11/80 = -33/240

-------------------------------------

-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm

The total change in the water level is [tex]-\frac{29}{24}[/tex]

'A fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.'

According to the given problem,

Change in first month =  [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex] + [tex]\frac{21}{80}[/tex] + [tex](-\frac{11}{80})[/tex]

                                    =   [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex]  + [tex]\frac{10}{80}[/tex]

                                    =   [tex]([/tex][tex]-1\frac{1}{3}[/tex] [tex])[/tex] + [tex]\frac{1}{8}[/tex]

                                    = [tex]\frac{1}{8} - \frac{4}{3}[/tex]

                                    = [tex]\frac{3 - 32}{24}[/tex]

                                    = [tex]-\frac{29}{24}[/tex]

Hence, we can conclude, the change in the water level is  [tex]-\frac{29}{24}[/tex]
