Answer:

x =±2 sqrt(6)

Step-by-step explanation:

x^2 = 24

Take the square root of each side

sqrt(x^2) = sqrt(24)

x = ±sqrt(4*6)

x =±sqrt(4) sqrt(6)

x =±2 sqrt(6)

Answer:

1:3

Step-by-step explanation:

The second cube is 3x bigger than the first cube, and since all sides of a cube are the same the ratio for the length of the edges will directly transfer over to the ratio of their volumes.

C. 1 : 27

As an example, let's say that n is equal to 1. The volume of the first cube is n*n*n, since n stands for the measurement of each edge. n*n*n=1*1*1=1 cubic meter. Now, onto the second cube. The volume of the second cube is 3n*3n*3n, since 3n stands for the measurement of each edge. 3n*3n*3n=3*3*3 ( since 3n=3*1=3 ) which is equal to 27. The ratio of the volume of the first cube to the volume of the second cube is represented by n : 3n. Substituting the n on both sides for the n in our example, we get a final result and ratio of 1 : 27.

Answer:

Step-by-step explanation:

Let,

The missing length be = x yd

As we know According to Pythagoras Theorem,

[tex] {50yd}^{2} = {30yd}^{2} + {x \: yd}^{2} [/tex]

[tex] = > 2500 = 900 + {x}^{2} [/tex]

[tex] = > {x}^{2} = 2500 - 900[/tex]

[tex] = > {x}^{2} = 1600[/tex]

[tex] = > x = \sqrt{1600} = \sqrt{40 \times 40} [/tex]

=> x = 40

Hence,

Missing length will be 40 yd (Ans)

Answer:

[tex]3x + ay = 50\\ay = 50-3x\\ay = -3x + 50\\y =\frac{-3x}{a} + \frac{50}{a} \\\\slope = \frac{-3}{a} \\\\9x -21y = 15\\-21y = 15 -9x\\21y = 9x - 15\\\\y=\frac{9x}{21} - \frac{15}{21} \\\\Slope = \frac{9}{21} \\\\Since \ equations \ are \ parallel \ = m_{1} m_{2} = 1\\\\\frac{-3}{a} \cdot\frac{9}{21} = 1 \\\\\frac{-27}{21a} = 1\\\\\\\frac{-9}{7} = a[/tex]

Answer:

The gold shipment truly is made of 75% gold, but the designer concludes that it is made of less than 75% gold. The designer will reject the shipment of gold and miss out on an honest business relationship with the supplier.

Step-by-step explanation:

Type I error is defined as the rejection of the true null hypothesis. It is also called as the 'false positive' conclusion or 'false positive' findings. The value of alpha or the significance level determines the probability of making the error type I.

In the context, it is given that for a gold piece to be of 18 karat , the piece of jewelry must be made of 75% of pure gold.

The null hypothesis is, H0: The proportion of metal that is gold is 75%

The alternative hypothesis is Ha: The proportion of metal that is gold is less than 75%.

Thus the type I error is when the gold shipment is made of 75% gold but the jewelry designer rejects the shipment thinking that the shipment is made of less than 75% gold.

Thus it shows the error of type I rejecting the null hypothesis.

Answer:

9n + 2.

Step-by-step explanation:

This is arithmetic with common difference d = 9.

nth term = a1 + d(n - 1)     (a1 = 11) 11 + 9n - 9

= 11 + 9(n - 1)

= 9n + 2.

Answer:

5?

Step-by-step explanation:

2x › 5 (buy at least 4)

so you can just start plugging numbers in.

I used 5, 5 times 2 is 10 which is 5 more that 5, which does met the quota.

Answer:

[tex]x \ge 4.5[/tex]

Step-by-step explanation:

The number 2x is larger than 5, so  2x - 5  is the difference between 2x and 5.  This difference is at least (greater than or equal to) 4.

[tex]2x-5 \ge 4\\\\2x \ge 9\\\\x \ge 4.5[/tex]

Answer:

169.56

Step-by-step explanation:

169.56

If the radius is 3 m and the height is 6 m. Then the volume of the cylinder will be 196.56 cubic meters.

Suppose that the radius of the considered right circular cylinder is 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

V = πr² h

Right circular cylinder is the cylinder in which the line joining the center of the top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

The radius is 3 m and the height is 6 m.

Then the volume of the cylinder will be

Volume = 3.14 x 3² x 6

Volume = 3.14 x 9 x 6

Volume = 169.56 m³
