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:

2,640

Step-by-step explanation:

To find the number of male students at the college, calculate the total number of students, then subtract the number of female students. The correct answer is option B: 2,640.

To find out how many male students are at the small private college, first, we need to determine the total number of students.

Since 9/20 of the students are female and there are 2,160 female students, we can set up a proportion to solve for the total number of students:

Since 9/20 represents the female students, 11/20 represents the male students.

Divide the total number of female students (2,160) by 9/20 to find the total number of students, which equals 4,800.

Subtract the total number of female students from the total number of students to find the number of male students, which equals 2,640.

Therefore, the answer is option B: 2,640.

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.

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: 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%

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.

A removable discontinuity is a type of discontinuity in a function where the function can be redefined at that point to make it continuous. It usually occurs when there is a hole or gap in the graph of the function.

A removable discontinuity, also known as a removable singularity, is a type of discontinuity in a function where the function can be redefined at that point to make it continuous.

The discontinuity is 'removable' because it can be 'filled in' or 'repaired' to make the function continuous.

This usually happens when there is a hole or gap in the graph of the function.

For example, consider the function f(x) = (x - 2)(x + 1) / (x - 2).

This function has a removable discontinuity at x = 2. If we simplify the function by canceling out the (x - 2) terms, we get f(x) = x + 1.

The simplified function is continuous at x = 2, even though the original function had a hole in the graph at that point.

It is important to note that not all discontinuities are removable.

There are other types of discontinuities, such as jump discontinuities and infinite discontinuities, which cannot be repaired to make the function continuous.
