Answer:
Rational
Step-by-step explanation:
Rational numbers are numbers you can use in a ratio, basically things like negative/regular numbers, and fractions, decimals! Since you have a decimal negative number, it would be rational. It can't be Irrational because only numbers that are complicated

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

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.

Step-by-step explanation:
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

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.

What is the price of 8 notebooks and 7 pens if 4 notebooks and 3 pens cost $96, while 2 pens and 2 notebooks cost $54?
Answer:
$204
Step-by-step explanation:
Create a system of equations where p is the price of a pen and n is the cost of a notebook:
4n + 3p = 96
2n + 2p = 54
Solve by elimination by multiplying the bottom equation by -2:
4n + 3p = 96
-4n - 4p = -108
-p = -12
p = 12
So, a pen costs $12. Plug this in as p into one of the equations, and solve for n:
2n + 2p = 54
2n + 2(12) = 54
2n + 24 = 54
2n = 30
n = 15
So, a notebook costs $15.
Using this, find the price of 8 notebooks:
15(8)
= 120
Find the price of 7 pens:
12(7)
= 84
Add this together:
120 + 84
= 204
So, the price of 8 notebooks and 7 pens is $204
Polygon with four sides, and the sum of the interior angles is equal to 360 degrees
Answer: I'm assuming your asking the length of each side. If so, each side is 90 degrees. If not, you should be more specific
Step-by-step explanation:
360 degrees divided by 4 sides equals 90 degrees for each side.

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
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

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.
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.

PLEASE ANSWER THIS AND SHOW WORK. FIND THE SURFACE AREA FOR THE FIGURE BELOW
Answer:
Total surface area of the given figure is 246.75 square mile.
Step-by-step explanation:
Surface Area of the given figure = Lateral surface area + Area of the base
Lateral surface area of the figure = Sum of the areas of 5 triangular surfaces
= [tex]5(\frac{1}{2} )(\text{Base})(\text{Slant height})[/tex]
= [tex]\frac{5}{2}(7)(9.3)[/tex]
= 162.75 mi²
Surface area of the pentagonal base = 84 mi²
Total surface area of the figure = 162.75 + 84
= 246.75 mi²
Therefore, total surface area of the given figure is 246.75 square mile.
