Chayton read a report that said the probability that a randomly selected American is left-handed is 14%.
He was curious how many left-handed students to expect in a class of 20 students.
He simulated 25 classes of 20 students where each student selected had a 0.14 probability of being left-
handed.
Chayton counted how many left-handed students were in each simulated class. Here are his results:​

An image is attached below for the graph of the function y = cos(x) + 3

A function such as the sin, cos, tan, cot, sec, and cosec of an angle or an arc expressed in terms of the ratios of pairs of sides of a right angled triangle.

The graph of cos(x) is a periodic function with time period 2π. After every 2π it repeats itself so we call it as a periodic function.

for x = 0

y = cos(0) + 3

y = 1 + 3

y = 4

for x = π/2

y = cos(π/2) + 3

y = 0 + 3

y = 3

An image graph of cos(x) + 3 is given try out different vales of x to understand more about how the function behaves.

Answer:

cos²x

Step-by-step explanation:

(a-b)(a+b)=a²-b²

sin²x+cos²x=1 => cos²x=1-sin²x

(1 − sin x)(1 + sin x)=1-sin²x=cos²x

The simplified value of the (1 − sin x)(1 + sin x) is cos² x.

The correct option is B.

To simplify the expression (1 − sin x)(1 + sin x), we can use the identity for the difference of squares, which states that (a − b)(a + b) = a² − b².

So, it can written as

(1 − sin x)(1 + sin x) = (1)² − (sin x)².

Now, using the identity sin² x + cos² x = 1, we can substitute (sin x)² with (1 − cos² x):

(1)² − (sin x)² = 1 − (1 − cos² x) = 1 − 1 + cos² x = cos² x.

Therefore, the simplified expression is cos² x.

The best buy for cereal is the 21-ounce size as it costs $0.185 per ounce, which is cheaper compared to the 18-ounce size ($0.266 per ounce) and the 32-ounce size ($0.203 per ounce).

To determine the best buy for cereal, we first need to calculate the price per ounce for each size. The formula to calculate is Price per Ounce = Total Price / Ounce Size. Using this formula, let's calculate for each cereal pack:

Based on these calculations, we see that the 21-ounce size cereal pack is the best buy, as it offers the lowest price per ounce.

The correct answer is 8 weeks.

Answer:

11 ft

Step-by-step explanation:

The area of a trapezoid is given as:

A = ½(a + b)h

Where a = length of one base of the trapezoid = 15 ft

b = length of the second base of th trapezoid

h = height of the trapezoid = 7.6 ft

When the area is 98.8 ft², the length of the second base will be:

98.8 = ½(a + 15) * 7.6

2 * 98.8 = (a + 15) * 7.6

197.6 / 7.6 = (a + 15)

26 = (a + 15)

=> a = 26 - 15 = 11 ft

The length of the second base if the trapezoid is 11 ft.

Answer:

0.545

Step-by-step explanation:

In the missing table the following information is shown:

Did You Watch More Than One Hour of TV Last Night?

3rd Period Class: Yes- 11 No- 6

6th Period Class: Yes- 12 No- 10

The probability that the student watched more than 1 hour of TV  given that he/she belongs to 6th period class is:

P(more than 1 hour of TV | 6th period class) = 12/(12+10) = 0.545

The probability (more than thanhour of TV | 6th period class).and rounded to the nearest thousandth is:

This refers to the chance occurrence of an event based on both dependent and independent variables.

Hence, from the complete question, there is the table which gives the following data;

Answer:

-sqrt(2)/2

Step-by-step explanation:

5pi/4 lies in the third quadrant with basic angle: 5pi/4 - pi = pi/4

sin(pi/4) = sqrt(2)/2

Since it's in quadrant 3, sin would be negative

sin(5pi/4) = -sqrt(2)/2

sqrt: square root

When the above math expression is evaluated,  the value of sin(5π/4) is -√2/2.

To evaluate sin(5π/4), we can use the unit circle or trigonometric identities.

The angle 5π/4 is located in the third quadrant of the unit circle, where the sine function is negative.

In the unit circle, at 5π/4, the corresponding point is (-√2/2, -√2/2). The y-coordinate of this point represents the value of the sine function.

Therefore, sin(5π/4) = -√2/2. hence, the value of sin(5π/4) is -√2/2.

Answer:

The probability that Jason will get  exactly 7 strikes out of 10 attempts is 0.117.

Step-by-step explanation:

We are given that Jason is a very good bowler and has proven over the  course of a season of league play that he gets a  STRIKE 50% of the time.

Also, Jason has been given 10 attempts.

The above situation can be represented through binomial distribution;

[tex]P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......[/tex]

where, n = number trials (samples) taken = 10 attempts

            r = number of success = 7 strikes

            p = probability of success which in our question is % of the time

                   he gets a strike, i.e; p = 50%

Let X = Number of strikes Jason get

So, X ~ Binom(n = 10, p = 0.50)

Now, probability that Jason will get  exactly 7 strikes out of 10 attempts is given by = P(X = 7)

                 P(X = 7)  =  [tex]\binom{10}{7} \times 0.50^{7} \times (1-0.50)^{10-7}[/tex]

                                =  [tex]120 \times 0.50^{7} \times 0.50^{3}[/tex]

                                =  [tex]120 \times 0.50^{10}[/tex]

                                =  0.117

Therefore, the probability that Jason will get  exactly 7 strikes out of 10 attempts is 0.117.

The probability that Jason will get exactly 7 strikes out of 10 attempts can be calculated using the binomial probability formula with a 50% strike rate.

The probability that Jason will get exactly 7 strikes out of 10 attempts, given a 50% strike rate, can be calculated using the binomial probability formula:

P(X = k) = C(n, k) * p[tex]^{(k)}[/tex] * (1 - p)[tex]^{(n - k)}[/tex]

Using the formula, we get:

P(X = 7) = C(10, 7) * (0.5)⁷ * (0.5)⁽¹⁰⁻⁷⁾

Calculating the combination C(10, 7) and following the formula yields the specific probability value for Jason to get exactly 7 strikes in 10 attempts.

Answer: 97% growth rate.

Step-by-step explanation:

Hi, to answer this question we have to analyze exponential function:

A = P (1 + r) t  

Where:

p = initial value

r = growth or decay rate (decimal form)

t= number of time intervals

A = value after t intervals

Replacing with the values given:

y=3400(1.97)^x

Where the term 1.97 = 1 + r

Solving for r:

1.97-1 = r

0.97 =r

Since the rate is positive, it is a  growth rate.

To determine the percentage we have to multiply it by 100

0.97 x 100 = 97%
