Select all true statements

First, calculate the total observed frequency;

[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]

[tex]Total = 90[/tex]

(a): Relative frequency of 4 is 2/9

Relative frequency is calculated by:

[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]

For roll 4

[tex]Observed\ frequency = 20[/tex]

So, the relative frequency is:

[tex]RF = \frac{20}{90}[/tex]

Simplify

[tex]RF = \frac{2}{9}[/tex]

(a) is true

(b): Experimental probability of 3 greater than its theoretical probability

The experimental probability is its relative frequency;

For roll 3

[tex]Observed\ frequency = 14[/tex]

The experimental probability is:

[tex]Pr = \frac{14}{90}[/tex]

Simplify

[tex]Pr = \frac{7}{45} = 0.156[/tex]

To calculate  the theoretical probability, w have:

[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space

[tex]n(S)= 6[/tex]

[tex]n(3) = 1[/tex] --- number of times 3 occur

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.

(b) is false

(c): Experimental probability of 2 greater than its theoretical probability

Using the explanations in (b), we have:

For roll 2

[tex]Observed\ frequency = 16[/tex]

The experimental probability is:

[tex]Pr = \frac{16}{90}[/tex]

Simplify

[tex]Pr = \frac{8}{45} = 0.178[/tex]

To calculate the theoretical probability, we have:

[tex]n(S)= 6[/tex]

[tex]n(2) = 1[/tex]

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.

(c) is true

(d): Relative frequency of 5 is 2/13

For roll 5

[tex]Observed\ frequency = 12[/tex]

The relative frequency is:

[tex]RF = \frac{12}{90}[/tex]

Simplify

[tex]RF = \frac{2}{15}[/tex]

(d) is true

1) find the total of candies

3 + 6 + 5 + 2 + 8 = 24

2) divide the number of yellow candies  for the total amount of candies

5/24 = 0.21 (correct)

3) use a proportion

6 : 24 = x : 200

x = (200 *6) / 24 = 50 (correct)

Answer:

Step-by-step explanation:

Total number of people who play sports in the Algebra 2 class:

[tex]21 - 9 = 12[/tex]

If there are 10 students who play Basketball, there are 2 students who ONLY play Baseball. If there are 9 students who play Baseball, there are 3 students who ONLY play Basketball.

So the number of students who play BOTH sports is:

[tex]12 - 2 - 3 = 12 - 5 = 7[/tex]

If 7 from the 21 Algebra 2 class students play BOTH sports, the probability is:

[tex]P = \frac{7}{21} = \frac{1}{3}[/tex]

Answer:

[tex]5 \div 11 \times 6 \div 7 = \frac{30}{77} [/tex]

The probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A place from this table is chosen at random. Let event A= the place is a city.

The total number of places are 7 given in the table.There are total three places which are city. Thus, the probability of a country to be a city is,

[tex]P(A)=\dfrac{3}{7}[/tex]

Now, for its complement, the probability of a place not be a city is,

[tex]P(A^c)=1-\dfrac{3}{7}\\P(A^c)=\dfrac{7-3}{7}\\P(A^c)=\dfrac{4}{7}[/tex]

Thus, the probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.

Answer:

m=3/4

Step-by-step explanation:

first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)

we have the equation 4x+3y=9

subtract 4x from both sides

3y=-4x+9

divide by 3

y=-4/3x+3

perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1

so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1

(m is the slope value)

-4/3m=-1

multiply by -3/4

m=3/4

therefore the slope of the perpendicular line is 3/4

The distance R from A and the bearing of R from A​ 15 km and 189° respectively.

The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.

The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.

Given that, a village R is 10 km from a point P on a bearing 25° from P. Another village A is 6 km from P on a bearing 162°.

We need to calculate, the distance R from A and the bearing of R from A​

We will use the Cosine Rule to determine the distance of R from A (p);

From Cosine Rule;

b² = a² + c²– 2ac Cos B

p² = a² + r² – 2ar Cos P

a= 10 km

Cos P = Cos 137

r = 6 km

p = ?

p² = a² + r² – 2ar Cos P

p² = 10² + 6² - 2 (10) (6) Cos 1370

p² = 100 + 36 – 120 (- 0.7314)

p² = 136 + 87.76

p² = 223.76

p = 14.95 = 15 km (approximated to the nearest km)

To find the bearing of the R from A,

we will apply Sine Rule;

From Sine Rule;

15Sin Ø = 10Sin 137 = 6.82

Sin Ø = 6.82/15 = 0.4547

Ø = ArcSin 0.4547 = 27°

Therefore, the bearing of R from A will be

∠ PRA = 180 – 137 – 27 = 160

The alternating angle to 25° at R is 65°

Then, the bearing of R from A = 270 -65-16 = 189°

Hence, the distance R from A and the bearing of R from A​ 15 km and 189° respectively.

Profit in 2006:  $7 million

First convert the percent into decimal: 9% = 0.09

Then use the percent increase then multiply by the number using this formula: ( 1 + r ) = ( 1 + 0.09) = 1.09

You only want to find how much profit in 2006, so you do this:

2003: 5.4  

2004: 5.4 (1.09) = 5.886  

2005: 5.886 (1.09) = 6.41574  

2006: 6.41574 (1.09) = 6.99316

Then you take 6.99316 and round to the nearest tenth of a million dollars.

7 million dollars.

Answer:

Miguel:

b = 2000 - 250m

Bartholomew:

b = 1500 - 150m

When m = 5

Step-by-step explanation:

Let

m = The number of months

b = balance on the credit card account in dollars.

Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month.

Miguel:

b = 2000 - 250m

Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month

Bartholomew:

b = 1500 - 150m

When will Miguel and Bartholomew owe the same amount of money?

Miguel balance = Bartholomew balance

2000 - 250m = 1500 - 150m

2000 - 1500 = -150m + 250m

500 = 100m

m = 500/100

m = 5 months
