Using the combination formula:

n! / (r!(n-r)!)

Where n is the number of people = 12 and r is the number of jurors = 9.

12! / (9!(12-9)!) = 220 combinations.

QUESTION 1

The given logarithmic expression is

$\log_4(\frac{1}{16})$

We rewrite $\frac{1}{16}$ in the index form to base 4.

This implies that;

$\log_4(\frac{1}{16})=\log_4(4^{-2})$

We now apply the power rule: $\log_a(m^n)=n\log_a(m^n)$ .

$\log_4(\frac{1}{16})=-2\log_4(4)$

Recall that logarithm of the base is 1.

$\log_4(\frac{1}{16})=-2(1)$

$\log_4(\frac{1}{16})=-2$

QUESTION 2

The given logarithm is;

$\log_2(\sqrt[5]{32})$

$\log_2(\sqrt[5]{2^5})$

This is the same as;

$\log_2(2^{5\times \frac{1}{5}})$

$\log_2(2^{1})$

$\log_2(2)=1$

Answer:

Ok ill help but please give me a lot of credit since i took the time to do it for you!

13 x 3 = 39, 39 x 2 = 78

9 x 3 = 27, 27 x 2 = 54

9 x 13 = 117, 117 x 2 = 234

234 + 78 + 54 = 366 mm

20 x 6 = 120, 120 x 2 = 240

4 x 20 = 80, 80 x 2 = 160

6 x 4 = 24, 24 x 2 = 48

240 + 160 + 48 = 448 cm

5 x 14 = 70, 70 x 2 = 140

5 x 16 = 80, 80 x 2 = 160

14 x 16 = 224 , 224 x 2 = 448

448 + 160 + 140 = 748 m

4 x 14 = 56, 56 x 2 = 112

17 x 4 = 68, 68 x 2 = 136

14 x 17 = 238, 238 x 2 = 476

476 + 112 + 136 = 724 ft

4 x 13 = 52, 52 x 2 = 104

13 x 19 = 247, 247 x 2 = 494

19 x 4 = 76, 76 x 2 = 152

104 + 494 + 152 = 750 in

14 x 9 = 126, 126 x 2 = 252

9 x 3 = 27, 27 x 2 = 54

3 x 14 = 42, 42 x 2 = 84

252 + 54 + 84 = 390 mm

7 x 12 = 84, 84 x 2 = 168

12 x 2 = 24, 24 x 2 = 48

2 x 7 = 14, 14 x 2 = 28

168 + 48 + 28 = 244 cm

6 x 4 = 24, 24 x 2 = 48

6 x 13 = 78, 78 x 2 = 156

4 x 13 = 52, 52 x 2 = 104

48 + 156 + 104 = 308 in

8 x 15 = 120, 120 x 2 = 240

4 x 15 = 60, 60 x 2 = 120

8 x 4 = 32, 32 x 2 = 64

240 + 120 + 64 = 424 ft

The cost of attending an amusement park is $10 for children and $20 for adults. On a particular day, the attendance at the amuse

vovangra [49]

Based on the figures above, the numbers of children that attended the park that day is 10,000.

<h3>What is the matrix equation about?</h3>

Fist we have to use the determinant to solve for c and as such:

$\frac{det.\frac{30000}{500000} \frac{1}{20} }{det. \frac{1}{10} \frac{1}{20} }$

= $\frac{30000 x 20 - 500000 x 1}{1 x 20 - 1 x 10}$

= 100000/10

=10,000

Therefore, Based on the figures above, the numbers of children that attended the park that day is 10,000.
