The coach of a college basketball team records the resting pulse rates of the team's players. A confidence interval for the mean resting pulse rate of all collegians based on these data is of little use because __________.
A) the sample size is small, so the margin of error will be large.
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
C) many of the students on the team may refuse to respond.

Step-by-step explanation:

The information given is not enough to determine the probability.

Given the number of male tenth-grader, and the number of all tenth-grader, the probability will then be: (number of male tentg-grader) divided by (the total number of students).

Answer:

What is the probability that a randomly chosen tenth-grader is male?  

✔ 80/154

What is the probability that a randomly chosen tenth-grader is male given that the tenth-grader prefers geometry?  

✔ 47/87

Are the events “male” and “geometry” independent?  

✔ no, P(male) does not equal P(male | geometry)

Answer:

81 shares

Step-by-step explanation:

Data provided in the question

Number of shares owned = 75 shares of stock

Per share value = $50

Dividend declared = 8%

Based on the above information. the number of shares owned is

[tex]= Number\ of \ shares\ owned \times dividend\ declared\ percentage + Number\ of \ shares\ owned[/tex][tex]= 75\shares \times 8\% + 75\shares[/tex]

= 81 shares

We simply added the number of shares owned and the number of shares owned after considered the dividend declared percentage so that the correct shares owned could arrive

Answer:

[tex]x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]

Step-by-step explanation:

x + 6x - 5 = 0

Since you can't factor the equation, use the quadratic formula.  

Your equation is already in the form of ax + bx + c.

[tex]x=\frac{-b\frac{+}{} \sqrt{b^{2} -4ac} }{2a}[/tex]

Based on your equation  a = 1  b = 6  c = -5.  Plug in the numbers and solve for x.

[tex]x = \frac{-6\frac{+}{} \sqrt{6^{2} -4(1)(-5)} }{2(1)} \\x = \frac{-6\frac{+}{} \sqrt{36+20 } }{2} \\x=\frac{-6\frac{+}{}\sqrt{56} }{2} \\x=\frac{-6\frac{+}{}2\sqrt{14} }{2} \\\\x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]

The Probability of an Event P(E) is that the spinner does not land on yellow is 11/7.

An experiment consists of spinning a spinner.

Red = 12

Blue = 10

Yellow = 6

We have to determine,

The experimental probability is that the spinner does not land on yellow.

The total number of spinner= 12+10+6

The total number of spinner=28.

Probability of an Event P(E) = Number of times an event occurs / Total number of trials.

The number of trials to not land on yellow is,

12+10=22

Therefore the Probability of an Event P(E) is given by,

[tex]P(E)=\frac{22}{28}[/tex]

[tex]P(E)=\frac{11}{14}[/tex]

Therefore option A is correct.

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The picture is the complete question.

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

[tex] Ways = 3*5*7= 105[/tex]

And that's equivalent to:

[tex] Ways= (3C1) (5C1) (7C1) =3*5*7=105[/tex]

Where C represent the term combinatory defined as:

[tex] nCx = \frac{n!}{x! (n-x)!}[/tex]

And then the number of ways to select the three books are 105, and the best option would be:

b). 105

Step-by-step explanation:

For this case we can use the multplication principle of counting or sometimes called the product rule.

We have a total of 3 novels, 5 biographies and 7 self-help books. And we can find the number of ways that a person can select the three books with theis product:

[tex] Ways = 3*5*7= 105[/tex]

And that's equivalent to:

[tex] Ways= (3C1) (5C1) (7C1) =3*5*7=105[/tex]

Where C represent the term combinatory defined as:

[tex] nCx = \frac{n!}{x! (n-x)!}[/tex]

And then the number of ways to select the three books are 105, and the best option would be:

b). 105

We want to see in how many different ways a person can select one book from 3 novels, one book from 5 biographies and one book from 7 self-help books, the correct option is b: 105.

To get the numbe of different ways, the first thing we need to do is find the selections.

Here we have 3 selections:

Now we need to find the number of options for each of these selections, and just multiply the numbers of options.

we have:

Number of different ways of selecting = 3*5*7 = 105

So the correct option is b.

Answer:

see below

Step-by-step explanation:

Let x be the first integer

x+1 is the next integer

x+2 = next integer

x+3 = last integer

The sum of the 4 integers is -10

x+ x+1 + x+2  + x+3 = -10

Combine like terms

4x+6 = -10

Subtract 6 from each side

4x+6-6 = -10-6

4x = -16

Divide each side by 4

4x/4 = -16/4

x = -4

x+1 = -3

x+2 = -2

x+1  =-1

The integers are -4, -3, -2 ,-1

Answer:

Jana is expected to win 40 more games over Ty.

Step-by-step explanation:

If Ty plays the game 120 times, he is expected to win in 1/3 part of 120 games, which is ( 1/3 * 120 =) 40 games.

If Jana plays the game 120 times, she is expected to win in 2/3 part of 120 games, which is ( 2/3 * 120 =) 80 games.

If Jana is expected to win 80 times an Ty is expected to 40 times, then Jana is expected to win ( 80 - 40 =) 40 more games over Ty.

Answer:

Center is at (-4, -2) and the radius = 5.

Step-by-step explanation:

Convert to Standard form:

x^2 + 8x + y2 + 4y - 5= 0  

Completing the square:

(x + 4)^2 - 16 + (y + 2)^2 - 4 = 5

(x + 4)^2 + (y + 2)^2  = 5 + 16 + 4

(x + 4)^2 + (y + 2)^2  = 25

(x - h)^2 + (y - k)^2 = r^2     Comparing:-

The center is at (-4, -2) and the radius = 5.

If you have 2 numbers add them up and divide them by 2. If you have 1 that is your medium. Hope this helps. The median is 70.

Step-by-step explanation:

Answer:

T = 2*PI* sq root (L / g)

Squaring both sides

T^2 = 4PI^2 * L/g

g = 4PI^2 * L / T^2

g = 4PI^2 * 1 / (3.27)^2

g = 39.4784176044  * 1 / 10.6929

g = 3.6920215848
