A local children’s museum surveys their members about what new exhibit they would like added to the museum. Twenty percent indicate they would like to see a planet and space exhibit added to the museum. The people surveyed are considered …
1 point
a. The population
b. The sample
c. A population statistic
d. A sample statistic
Answer:D
Step-by-step explanation:
The people surveyed are considered the sample. Therefore, the answer is B, the sample.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
In statistics, a population is the entire group of individuals, objects, or events that we want to study and make inferences about. A sample, on the other hand, is a smaller subset of the population that we actually observe or measure in order to make inferences about the population.
In this scenario, the local children's museum surveyed a group of its members to find out what new exhibit they would like added to the museum. The individuals who responded to the survey constitute a subset of the entire population of members who could have responded. Therefore, the people surveyed are considered the sample.

THE CORRECT ANSWER IS 57 CM³
Explanation:
Let's consider the vertical block first, having height 9 cm, length 1 cm, width 5 cm.
Hence the volume of that block = l.w.h = 9×5×1 = 45 cm³
Coming to the horizontal block, having height 4 cm, width 3cm, & length 1 cm.
Hence the volume of that block will be = 4×3×1 = 12 cm²
The total volume of irregular figure = Volume of vertical block + horizontal block = 45+12 = 57 cm³

157
Step-by-step explanation:
The terminal side of θ in standard position contains the point (–4, 3). Find the exact values of the six trigonometric functions of θ. (show all of your work) *
Answer:
When we have a rectangular point (x, y), the angle between the x-axis and a ray that connects the origin with this point is given by:
Tan(θ) = y/x.
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
So for the point (-4,3) we have:
x = -4
y = 3
√( (-4)^2 + 3^2) = √(16 + 9) = √25 = 5
Then:
Tan(θ) = 3/-4 = -(3/4)
Sin(θ) = 3/5
Cos(θ) = -4/5
And for the other 3 trigonometric functions (the inverses of the 3 above ones) we have:
Ctg(θ) = 1/Tan(θ) = -4/3
Csc(θ) = 1/Sin(θ) = 5/3
Sec(θ) = 1/Cos(θ) = -4/5
can someone please tell me what angle x is
Answer:
it's an angle X duh he he he be
Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Answer:
18.4 cm²
Step-by-step explanation:
Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Volumen = Área de la base × Altura
Área de la base = Volumen / Altura
= 184 cm³ / 10 cm
Área de la base = 18.4 cm²
Por lo tanto, el área de la base es de 18.4 cm².
The faces of a fair 6 - sided cube are numbered 1 through 6. What is the probability that a 2 will land face up on the next roll? Give your answer as a fraction in simplest form and the percent.
Answer:
You will have a 1/6 probability of getting a 2 that will land face up on the next roll.
Step-by-step explanation:
There is only one two on the cube, which means you will have 1 chance out of 6 of getting a 2.
Jamie uses exactly 18 inches of dental floss every time she flosses her teeth. The package of dental floss she just bought contains 27 yards. How many times can Jamie floss her teeth with the amount of floss in this package?
Answer:
54 times
Step-by-step explanation:
36 inches = 1 yard
Since there are 27 yards, you multiply 36 by 27 = 972
If you use 18 inches each time, you would divide 972 by 18.
972/18= 54
So, Jamie could flow her teeth 54 times.

Calinda is painting the design on her bedroom wall. The large circle has a diameter of 32 inches. To the nearest square inch, how much paint swill she need for the shared reign on
Answer:
804 inches
Step-by-step explanation:
Amount of paint she would need is equal to the area of the circle
Area of a circle = πr²
π = 3.14
r = 32/2 = 16
The diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 16² = 804 in

Step-by-step explanation:
A random variable X follows a Binomial distribution; i.E. X ~ B(12, p) with a variance of 1.92. Compute the possible values of p
==================================================
Explanation:
Any binomial distribution has two unique components to it: The number of trials n, and the probability of success p.
We're given n = 12, and we need to find p.
The variance of a binomial probability distribution is given by the formula n*p*(1-p). Plug in n = 12 and set this equal to 1.92
So the equation to solve is 12p*(1-p) = 1.92
Solve for p using a graphing calculator or you could apply the quadratic formula. Either way, you should get the two results of p = 0.2 and p = 0.8
Note that if p = 0.2, then 1-p = 1-0.2 = 0.8, and things flip around when p = 0.8.

The dimensions of a rectangle can be expressed as x−1 and x+5. If the area of the rectangle is 91 square inches, what are the dimensions of the rectangle? Make sure to enter BOTH dimensions.
Answer:
13 x 7
Step-by-step explanation:
area = L x W
91 = (x - 1)(x + 5)
x² + 5x - x - 5 = 91
combine like terms:
x² + 4x - 5 = 91
subtract 91 to each side of the equation:
x² + 4x - 96 = 0
factor:
(x + 12)(x - 8)
x = 8
x - 1 = 7
x + 5 = 13
Cone A and cone B are similar . Find the volume of cone B. Leave your answer in terms of pi.
Answer:
144π
Step-by-step explanation:
So you have the volume of A is 96π.
Since the radius of cone A is 6 and the radius of cone B is 9, the ratio of the volumes is 2:3 since it says that they are similar.
Cone B's volume is 1.5 times bigger than cone A.
96π * 1.5 = 144π
