10 A three-dimensional letterH is formed by joining two identical cuboids and a cube.​

Answer:

5/12

Step-by-step explanation:

The required value in fraction form is 5/12

Given the expression

1/2 x 5/6

We are to express in fraction form. To do this we will multiply the numerator and denominator together to have:

1/2 x 5/6

= (1 * 5)/(2 * 6)

= 5/12

Hence the required value in fraction form is 5/12

Answer:

The angle of elevation from Ethan to the space shuttle is approximately 0.405º.

Step-by-step explanation:

Let O and A the locations observation spot and the space shuttle, respectively. BA is the height of the space shuttle from the ground. All length are measured in miles. We include a simplified geometrical representation of the situation.

Since a right triangle is formed, we can find the angle of elevation ([tex]\theta[/tex]), measured in sexagesimal degrees, by the following inverse trigonometrical relationship:

[tex]\theta = \tan^{-1}\left(\frac{BA}{OB} \right)[/tex] (1)

Where OB is the distance from the observation spot to the point just below the space shuttle.

If we know that [tex]OB = 99\,mi[/tex] and [tex]BA = 0.7\,mi[/tex], then angle of elevation from Ethan to the space shuttle is:

[tex]\theta = \tan^{-1}\left(\frac{0.7\,mi}{99\,mi} \right)[/tex]

[tex]\theta \approx 0.405^{\circ}[/tex]

The angle of elevation from Ethan to the space shuttle is approximately 0.405º.

Answer:

Perimeter: 2(3x+6)+ 2(2x-4)

X=9

Step-by-step explanation:

In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:

Perimeter: 2(heights)+ 2(bases)

Perimeter: 2(3x+6)+ 2(2x-4)

IN order to solve for X we just have to insert the value of perimeter, which is 94:

Perimeter: 2(3x+6)+ 2(2x-4)

94=2(3x+6)+ 2(2x-4)

94= 6x+12+4x-8

94=10x+4

94-4=10x

x=90/10

x=9

So the value of x would be 9.

Answer:

the  probability that they both were sentenced to prison is 0.1740

Step-by-step explanation:

The computation of the probability is given below;

P(sentenced) is

= (367 + 68) ÷ 1043

= 0.4171.

Now

P(2 persons senteced to prison) is

= 0.4171 × 0.4171

= 0.1740

hence, the  probability that they both were sentenced to prison is 0.1740

Answer:

A sample of 217 is needed.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

If the population standard deviation is $3,750 how large should the sample be if margin of error is $500

We have that [tex]\sigma = 3750[/tex].

We need a sample of n, and n is found when [tex]M = 500[/tex]. So

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

[tex]500 = 1.96*\frac{3750}{\sqrt{n}}[/tex]

[tex]500\sqrt{n} = 1.96*3750[/tex]

[tex]\sqrt{n} = \frac{1.96*3750}{500}[/tex]

[tex](\sqrt{n})^{2} = (\frac{1.96*3750}{500})^{2}[/tex]

[tex]n = 216.1[/tex]

Rounding up

A sample of 217 is needed.

Answer:

[tex]P(60mph\ or\ 70mph) = 0.38[/tex]

[tex]P(x>65mph) = 0.62[/tex]

[tex]P(x \le 70mph) = 0.74[/tex]

Step-by-step explanation:

Given

Speed Limits --- States

60 mph  ---------- 1

65 mph ----------- 18

70 mph ----------- 18

75 mph ---------- 13

Total -------------- 50

Solving (a): Probability of 60mph or 70mph

This is represented as:

[tex]P(60mph\ or\ 70mph)[/tex]

We only consider states with speed limits of 60 and 70mph.

So, we have:

[tex]P(60mph\ or\ 70mph) = P(60mph) + P(70mph)[/tex]

[tex]P(60mph\ or\ 70mph) = \frac{1}{50} + \frac{18}{50}[/tex]

Take L.C.M

[tex]P(60mph\ or\ 70mph) = \frac{1+18}{50}[/tex]

[tex]P(60mph\ or\ 70mph) = \frac{19}{50}[/tex]

[tex]P(60mph\ or\ 70mph) = 0.38[/tex]

Solving (b): Greater than 65mph

This is represented as:

[tex]P(x>65mph)[/tex]

We only consider states with speed limits of 70 and 75mph.

So, we have:

[tex]P(x>65mph) = P(70mph) + P(75mph)[/tex]

This gives:

[tex]P(x>65mph) = \frac{18}{50} + \frac{13}{50}[/tex]

Take L.C.M

[tex]P(x>65mph) = \frac{18+13}{50}[/tex]

[tex]P(x>65mph) = \frac{31}{50}[/tex]

[tex]P(x>65mph) = 0.62[/tex]

Solving (c): 70mph or less

This is represented as:

[tex]P(x \le 70mph)[/tex]

We only consider states with speed limits of 60, 65 and 70mph.

So, we have:

[tex]P(x \le 70mph) = P(60mph) + P(65mph) + P(70mph)[/tex]

This gives:

[tex]P(x \le 70mph) = \frac{1}{50} + \frac{18}{50} + \frac{18}{50}[/tex]

Take L.C.M

[tex]P(x \le 70mph) = \frac{1+18+18}{50}[/tex]

[tex]P(x \le 70mph) = \frac{37}{50}[/tex]

[tex]P(x \le 70mph) = 0.74[/tex]

Answer: =1/2x+1/3

Step-by-step explanation:

The equivalent expression is 1/2x+ 1/3.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 more than half of it. In a mathematical expression, this statement is denoted by the expression x/2 + 6.

Given:

1/4x+1+3/4x-2/3-1/2x

Now, solving the above expression

1/4x+1+3/4x-2/3-1/2x

= 1/4x + 3/4x - 1/2x + 1 - 2/3

= 4/4x - 2/4x + 1/3

= 2/4x + 1/3

= 1/2x + 1/3

Hence, the equivalent expression is 1/2x+ 1/3.
