The probability calculations for the bowler indicate that she has a 0.33% chance of not getting a strike for three consecutive frames, a 1.9% chance of getting her first strike in the third frame, a 99.66% chance of getting at least one strike in the first three frames, and a 3.4% chance of bowling a perfect game.

The subject here is probability, with the scenario provided being that a bowler can strike 85% of the time. We assume that all strikes are independent events, meaning one strike does not affect the probability of the next strike.

The probability of her not getting a strike in one turn is 1 - 0.85 = 0.15 (the complement of her strike rate). For three consecutive frames without a strike, we multiply these probabilities because of their independence: 0.15 * 0.15 * 0.15 = 0.003375 or 0.33%.

This means not striking in the first two frames and getting a strike in the third. Calculate this by multiplying the probabilities: 0.15 * 0.15 * 0.85 = 0.01912 or 1.9%.

This is best calculated by subtracting the probability of no strikes in 3 frames (found in part a) from 1, as it is the complement: 1 - 0.003375 = 0.996625 or 99.66%.

A perfect game requires 12 consecutive strikes. Multiply the probability of a strike (0.85) by itself 12 times : 0.85^12 = 0.034 (3.4% chance of a perfect game).

The step-by-step probabilities for varying scenarios in a bowling game are: a) 0.003375 for no strikes in three frames, b) 0.019125 for the first strike in the third frame, c) 0.996625 for at least one strike in three frames, and d) 0.1489 for a perfect game.

Probability Calculations for a Bowler

A certain bowler has an 85% chance of bowling a strike. Let's break down each part of the question:

a) Probability of three consecutive frames without a strike

The probability of not getting a strike in one frame is 1 - 0.85 = 0.15. Therefore, the probability of not getting a strike in three consecutive frames is:

(0.15) × (0.15) × (0.15) = 0.003375

b) Probability of making the first strike in the third frame

The probability of not getting a strike in the first two frames but getting a strike in the third frame is:

(0.15) × (0.15) × (0.85) = 0.019125

c) Probability of at least one strike in the first three frames

First, find the probability of no strikes in three frames, which we've already calculated as 0.003375. Therefore, the probability of at least one strike is:

1 - 0.003375 = 0.996625

d) Probability of a perfect game (12 consecutive strikes)

The probability of getting a strike in each of the 12 frames is:

(0.85)¹² = 0.1489

Answer:

BFD

Step-by-step explanation:

The measure of BFD refers to the angle measurement in a geometric figure formed by points B, F, and D. It's impossible to provide a definitive answer without further context or a diagram. The measure of an angle depends on point positions in a geometrical shape and information provided.

Inquiring about the measure of BFD likely refers to the measure of an angle in a geometric shape with points labeled as B, F, and D. However, without additional information or context such as a diagram displaying details of the geometrical figure involved, it is impossible to definitively provide the exact measure of angle BFD. It's crucial to understand that the measure of an angle depends upon the positions of the points and any information given in an accompanying diagram or problem. For a closer grasp of the concept, remember that in a triangle, for instance, the sum of all angles is always 180 degrees. Thus, if two angles are given, you can determine the measure of the third angle.

C) Reject [tex]H_0[/tex] if t < -1.711

Step-by-step explanation:

We are given that a certain chemical pollutant in the Arkansas River has been constant for several years with mean μ = 34 ppm (parts per million).

Also, it is given that the level of significance is 0.05 and a sample size of 25 is taken.

Let [tex]\mu[/tex] =  average chemical pollutant in the Arkansas River

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 24 ppm     {means that the average is same as before with improved filtration devices}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 24 ppm      {means that they have lowered the average with improved filtration devices}

Now, t test statistics is given by; T.S.  =  [tex]\frac{\bar X -\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, n = sample size = 25

n - 1 = degree of freedom = 25 - 1 = 24

Now, at 0.05 significance level in the t table, the critical value at 24 degree of freedom is given as - 1.711 for left tailed test.

So, we will reject our null hypothesis when the t test statistics is less than the critical value of t which means reject null hypothesis if t < -1.711.

Answer:

In converting a mixed number to an improper fraction, you would have to multiply the denominator to the whole number, once you do that you have to add the product to the numerator. The denominator would still stay the same.

A. 1 7/16 = 23/16

B. 11 5/9 = 104/9

C. 30 5/7 = 215/7

D. 10 10/13 = 140/13

E. 24 3/5 = 123/5

F. 129 1/2 = 259/2

~hope this helps~

To convert mixed numbers to improper fractions, multiply the whole number part by the denominator of the fraction, add the numerator, and keep the denominator the same. Examples include converting 1 7/16 to 23/16 and 11 5/9 to 104/9.

To change each mixed number into an equal improper fraction, you should follow a consistent method. This involves multiplying the whole number by the denominator of the fraction part and then adding the numerator of the fraction part. The resulting sum becomes the numerator of the improper fraction, with the denominator remaining the same as in the original fraction.

a. 1 7⁄16: Multiply 1 by 16 (the denominator) = 16, then add 7 (the numerator) = 23. Thus, 1 7⁄16 equals 23/16.

b. 11 5⁄9: Multiply 11 by 9 = 99, then add 5 = 104. So, 11 5⁄9 equals 104/9.

c. 30 5⁄7: Multiply 30 by 7 = 210, then add 5 = 215. Therefore, 30 5⁄7 equals 215/7.

d. 10 10⁄13: Multiply 10 by 13 = 130, add 10 = 140. Hence, 10 10⁄13 is 140/13.

e. 24 3⁄5: Multiply 24 by 5 = 120, add 3 = 123. Thus, 24 3⁄5 equals 123/5.

f. 129 1⁄2: Multiply 129 by 2 = 258, add 1 = 259. Therefore, 129 1⁄2 is 259/2.

To find the total area of the construction paper needed for Natalie's project, multiply the length by the width of each rectangle and add them together.

To find the total area of the construction paper needed for Natalie's project, we need to find the area of each rectangle and then add them together.

Rectangle 1:

Length = 6 inches and width = 13 1/2 inches.

To find the area, multiply the length by the width: 6 inches x 13 1/2 inches = 81 square inches.

Rectangle 2:

Length = 10 1/3 inches and width = 10 1/2 inches.

To find the area, multiply the length by the width: 10 1/3 inches x 10 1/2 inches = 108 1/3 square inches.

Total area:

Add the areas of both rectangles: 81 square inches + 108 1/3 square inches = 189 1/3 square inches.

Therefore, Natalie needs a total of 189 1/3 square inches of construction paper for her project.

Natalie needs a total of 149 square inches of construction paper for her project.

To find the total square inches of construction paper needed for Natalie's project, we calculate the area of each rectangle and then add them together.

1. Area of the first rectangle:

[tex]\( \text{Area}_1 = \text{length} \times \text{width} = 6 \times 13\frac{1}{2} \) square inches.[/tex]

2. Area of the second rectangle:

[tex]\( \text{Area}_2 = \text{length} \times \text{width} = 10\frac{1}{3} \times 10\frac{1}{2} \) square inches.[/tex]

3. Calculate the total area:

  Total area = Area of first rectangle + Area of second rectangle.

Let's compute:

1. [tex]\( \text{Area}_1 = 6 \times 13\frac{1}{2} = 6 \times \frac{27}{2} = \frac{81}{2} = 40.5 \) square inches.[/tex]

2. [tex]\( \text{Area}_2 = 10\frac{1}{3} \times 10\frac{1}{2} = \frac{31}{3} \times \frac{21}{2} = \frac{651}{6} = 108.5 \) square inches.[/tex]

3. Total area = 40.5 + 108.5 = 149 square inches.

So, Natalie needs a total of 149 square inches of construction paper for her project.

This is a binomial distribution because the probabilities are either that of success or failure.

If probability of success, p = 3/8 = 0.375, then probability of failure, q = 1 - p = 1 - 0.375 = 0.625

The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = represents the probability of failure.

n represents the number of trials or sample.

n = 8

13) P(x = 3) = 8C3 × 0.375^3 × 0.625^(8 - 3) = 0.28

14) P(x = 6) = 8C6 × 0.375^6 × 0.625^(8 - 6) = 0.03

15) P(x = 1) = 8C1 × 0.375^1 × 0.625^(8 - 1) = 0.11

16) P(x = 5) = 8C5 × 0.375^5 × 0.625^(8 - 5) = 0.1

17) P(x ≥ 1) = 1 - P(x < 1)

P(x < 1) = P(x = 0)

P(x = 0) = 8C0 × 0.375^0 × 0.625^(8 - 0) = 0.023

P(x ≥ 1) = 1 - 0.023 = 0.977

18) P(x ≥2) = 1 - P(x < 2)

P(x < 2) = P(x = 0) + P(x = 1)

P(x = 0) = 8C0 × 0.375^0 × 0.625^(8 - 0) = 0.023

P(x = 1) = 8C1 × 0.375^1 × 0.625^(8 - 1) = 0.11

P(x ≥ 2) = 1 - (0.023 + 0.11) = 0.867

19) P(x ≥ 6) = P(x = 6) + P(x = 7) + P(x = 8)

P(x = 6) = 8C6 × 0.375^6 × 0.625^(8 - 6) = 0.03

P(x = 7) = 8C7 × 0.375^7 × 0.625^(8 - 7) = 0.005

P(x = 8) = 8C8 × 0.375^8 × 0.625^(8 - 8) = 0.0004

P(x ≥ 6) = 0.03 + 0.005 + 0.0004 = 0.0354

20) P(x ≥ 7) = P(x = 7) + P(x = 8)

P(x ≥ 7) = 0.005 + 0.0004 = 0.0054

ANSWER:

P(t) is the ratio of the number of melanophores to the number of xanthophores per unit time.

Therefore P(t) = 1.55

Step-by-step explanation:

KEY NOTE:

I) 10% of melanophore converts to Xanthophore per unit time.

II) 40% of Xanthophore converts to melanophore per unit time.

III) 10 melanophore and 20 Xanthophore are born per unit time

IV) 10% of Xanthophore die per unit time.

STEP 1: Conversion rate to number of birth per unit time.

For M(t) 10% of 10 = 1

For X(t) 40% of 20 = 8

Therefore;

M(t) = 10 + 8 - 1 = 17

X(t) = 20 + 1 - 8 = 13

STEP 2:

10% of Xanthophore die per unit time.

10% of 20 = 2

Therefore X(t) is;

13 - 2 = 11

The total X(t) = 11

The total M(t) = 17

P(t) = M(t)/X(t) = 17÷ 11 = 1.55

[tex]\mathbf{f(x) = -5x^3 +235x^2 - 3400x + 20000}[/tex]

Differentiate, to calculate the rate of change

[tex]\mathbf{f'(x) = -15x^2 +470x- 3400}[/tex]

Set to 0

[tex]\mathbf{ -15x^2 +470x- 3400 = 0}[/tex]

Divide through by 5

[tex]\mathbf{ -3x^2 +94x- 680 = 0}[/tex]

Using a calculator, we have:

[tex]\mathbf{x = \{20,11.3\}}[/tex]

The domain is given as: [tex]\mathbf{10 \le x \le 40}[/tex]

When x = 10, we have:

[tex]\mathbf{f'(10) = -15(10)^2 +470(10)- 3400 = -200}[/tex]

When x = 11.3, we have:

[tex]\mathbf{f'(11.3) = -15(11.3)^2 +470(11.3)- 3400 = -4.35}[/tex]

When x = 20, we have:

[tex]\mathbf{f'(20) = -15(20)^2 +470(20)- 3400 = 0}[/tex]

When x = 40, we have:

[tex]\mathbf{f'(40) = -15(40)^2 +470(40)- 3400 = -8600}[/tex]

The value of f'(x) increases at x = 10 to 20.

Hence, the rate of change increases at: (10, 20)
