Use the probability distribution table to answer the question.
What is P(X ≥ 2)?
Enter your answer, as a decimal, in the box.
Answer:
0.88
Step-by-step explanation:
P(x≥2) = P(x=2) + P(x=3) + P(x=4) + P(x=5) + P(x=6)
P(x≥2) = 0.21 + 0.35 + 0.21 + 0.06 + 0.05
P(x≥2) = 0.88
Or, you can calculate it as:
P(x≥2) = 1 - P(x=1) - P(x=0)
P(x≥2) = 1 - 0.09 - 0.03
P(x≥2) = 0.88

What is the interquartile range of the data?
I think the answer is B.
Answer:
No, correct option is (A) 117.5
Step-by-step explanation:
Interquartile range (IQR) measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile. i.e.
IQR = Q₃ - Q₁
For finding the Interquartile Range of the data:
100, 120, 130, 188, 196, 220, 265, 300
Divide the data into two parts:(100, 120, 130, 188) (196, 220, 265, 300)
2. Now finding the medians of both halves of the data that will be our First and Third Quartile of data.
So, Q₁ = 125 and Q₃ = 242.5
Now, using IQR = Q₃ - Q₁
= 242.5 - 125 = 117.5
Hence, Correct option is Option (A).

Person is 75 feet from a hot air balloon.
The balloon goes straight up in the air.
The angle of elevation is 45°.
How high is the balloon?
Answer:
75 feet
Step-by-step explanation:
This is a right triangle because the balloon went straight up. The other angle being 45 means it is an isosceles right triangle. This means the legs are the same length. Since the person is 75 feet away, the balloon is 75 feet up.

What is the perimeter, in square centimeters, of a rectangle that has a length of 4 centimeters and a width of 15 millimeters? 38 cm 19 cm 5.5 cm 11 cm
Answer:
11 cm
Step-by-step explanation:
The rectangle width is 15 mm, which is the same as 1.5 cm.
The formula for P is P = 2W + 2L.
Here, with W = 1.5 cm and L = 4 cm, P = 2(1.5 cm) + 2(4 cm) = 11 cm
Answer:
11
Step-by-step explanation:
15 millimeters is 1.5 cm
1.5 + 1.5 + 4 + 4 = 11 cm

The president's company makes money from almonds, so he wants people to believe that almonds are good for one's teeth so that they buy more almonds.
Answer:
B. The president wants people to believe that almonds are good for one's teeth so that they buy more almonds.
Step-by-step explanation:
The report shows that people who eat a handful of almonds each day have 10% fewer cavities.
The most likely reason the president releases such report is - B. The president wants people to believe that almonds are good for one's teeth so that they buy more almonds.
The report is a way to emphasize that consuming almonds will help in reducing cavities. This is a great marketing skill by the President as making people believe the effects of almonds, will help in more sales of almonds.
The standard form of the equation of a circle is (x−4)2+(y−2)2=9. What is the general form of the equation?
x2+y2+8x+4y−29=0

Answer:
[tex]x^{2}+y^{2}-8x-4y+11=0[/tex]
Step-by-step explanation:
we have
[tex](x-4)^{2}+(y-2)^{2}=9[/tex]
The general equation of the circle is equal to
[tex]x^{2}+y^{2}+Ax+By+C=0[/tex]
Convert the standard form to a general form
[tex](x-4)^{2}+(y-2)^{2}=9\\ \\(x^{2} -8x+16)+(y^{2}-4y+4)=9\\ \\x^{2}+y^{2}-8x-4y+20-9=0\\ \\x^{2}+y^{2}-8x-4y+11=0[/tex]
The difference of the square of a number and 16 is equal to 6 times that number. Find the negative solution
Answer:
the negative solution. It is n = -2
Step-by-step explanation:
Let n represent the number. Then n² - 16 = 6n, and, after rearrangement,
n² - 6n - 16 = 0. This factors as follows:
n² - 6n - 16 = 0 = (n - 8)(n + 2) = 0, and so n = 8 or n = -2.
We are to find the negative solution. It is n = -2.

Answer:
301.6 ft³
Step-by-step explanation:
The volume (V) of a cone is calculated using the formula
V = [tex]\frac{1}{3}[/tex] × area of base × perpendicular height (h)
h can be calculated by using Pythagoras' identity in the right triangle
with hypotenuse = 10 and legs 6 and h, thus
h² + 6² = 10²
h² + 36 = 100 ( subtract 36 from both sides )
h² = 64 ( take the square root of both sides )
h = [tex]\sqrt{64}[/tex] = 8
Hence
V = [tex]\frac{1}{3}[/tex] × π × 6² × 8
= [tex]\frac{1}{3}[/tex] × 288π = [tex]\frac{288\pi }{3}[/tex] ≈ 301.6

A quadrilateral is graphed in the coordinate plane below. Which classification best describes the quadrilateral (parallelogram, rhombus, etc.)?
Answer:
Trapezoid
Step-by-step explanation:
Given quadrilateral has vertices at points A(-2,-1), B(3,13), C(15,5) and D(13,-11).
Find slopes of lines AD and BC:
[tex]\text{Slope}_{AD}=\dfrac{y_D-y_A}{x_D-x_A}=\dfrac{-11-(-1)}{13-(-2)}=\dfrac{-11+1}{13+2}=\dfrac{-10}{15}=-\dfrac{2}{3}\\ \\\text{Slope}_{BC}=\dfrac{y_C-y_B}{x_C-x_B}=\dfrac{5-13}{15-3}=\dfrac{-8}{12}=-\dfrac{2}{3}[/tex]
Since the slopes are the same, lines AD and BC are parallel.
Find slopes of lines ABD and CD:
[tex]\text{Slope}_{AB}=\dfrac{y_B-y_A}{x_B-x_A}=\dfrac{13-(-1)}{3-(-2)}=\dfrac{14}{5}\\ \\\text{Slope}_{CD}=\dfrac{y_D-y_C}{x_D-x_C}=\dfrac{-11-5}{13-15}=\dfrac{-16}{-2}=8[/tex]
Since the slopes are different, lines AB and CD are not parallel.
This means quadrilateral ABCD is trapezoid (two opposite sides - parallel and two another opposite sides - not parallel)

Terms that have the same variable part are called like terms. Like terms can be added or subtracted to form a single term.
1.
16x - 4x = -48
First, combine the like terms 16x and -4x.
12x = -48
Now divide both sides by 12.
x = -4
2.
7m - 5 - 13m = 25
First, combine the like terms 7m and -13m.
-6m - 5 = 25
Now add 5 to both sides.
-6m = 30
Divide both sides by -6.
m = -5
3.
12.25 = 0.5q + 3.75
Subtract 3.75 from both sides.
8.5 = 0.5q
Multiply both sides by 2.
17 = q
q = 17
4.
2(2x - 4) + x = 7
Distribute the 2.
4x - 8 + x = 7
Combine 4x and x.
5x - 8 = 7
Add 8 to both sides.
5x = 15
Divide both sides by 5.
x = 3
5.
8 = 3(3x + 8) - x
Distribute the 3.
8 = 9x + 24 - x
Combine 9x and -x.
8 = 8x + 24
Subtract 24 from both sides.
-16 = 8x
Divide both sides by 8.
-2 = x
x = -2

Enter your answer, rounded to two decimal places, in the box.
The answer will be 3.33
Hope this Help:)
Answer:
6.22
Step-by-step explanation:
First find the mean:
μ = (105+104+110+112+114+108+108+109) / 8
μ = 108.75
The standard deviation is then:
σ² = [(105-108.75)²+(104-108.75)²+(110-108.75)²+(112-108.75)²+(114-108.75)²+(108-108.75)²+(108-108.75)²+(109-108.75)²] / 8
σ² = 77.5 / 8
σ = 3.11
Margin of error is ±2σ, so ME = ±6.22.
A three-dimensional figure with one circular or elliptical base and a curved surface that joins the base to the vertex is called _____
Answer:
a cone
Step-by-step explanation:
If the base is circular, then the cone is said to be a "regular" or "circular" cone, much like an ice cream cone.
If the base is elliptical, then it becomes an "elliptical" cone.
Both shapes can be right (where the perpendicular line dropping from the vertex lands on the exact center of the base) or oblique (when the line dropping from the vertex doesn't land on the center of the base)

Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -6 and 162, respectively.
Select one:
a. an = 2 • 3n - 1
b. an = 2 • (-3)n - 1
c. an = 2 • 3n
d. an = 2 • (-3)n + 1
Answer:
b. an = 2 • (-3)^(n - 1)
Step-by-step explanation:
Before we test a solution or two, we can easily discard most of them.
We see the values alternate of signs (-5 for the 2nd term and +162 for the 5th term)... so the progression factor has to be negative (in order to alternate sign). That already excludes answers A and C.
Normally, a geometric progression has the (n-1) exponent, not (n+1), so our chances seem to be better with B.
We can test both D and B with n = 2, to obtain -6
Let's test answer D before:
[tex]a_{2} = 2 * (-3)^{2+1} = 2 * (-3)^{3} = 2 * -27 = -54[/tex]
The result is -54, not -6... so it's not the right result.
Let's test answer B then:
[tex]a_{2} = 2 * (-3)^{2-1} = 2 * (-3)^{1} = 2 * -3 = -6[/tex]
Right! Let's verify with n=5 to get 162:
[tex]a_{5} = 2 * (-3)^{5-1} = 2 * (-3)^{4} = 2 * 81 = 162[/tex]
Confirmed, answer is B. an = 2 • (-3)^(n - 1)

Answer:
Step-by-step explanation:
The trick here (and it is tricky!) is to find the area of the parallelogram as a whole based on the information you're given, and then use that area to solve for h. If we look at the parallelogram sideways and use 5.5 as the height, the base is 9.9. The area for a parallelogram is A = bh, so A = 9.9(5.5) so
A = 54.45 in squared. Now we will use that area value along with the height of h and the base of 11. Remember, just because we are using different numbers this time, the area of the parallelogram doesn't change. Therefore,
54.45 = 11(h) and
h = 4.95 in.

The results of a poll show that the percent of people who want a new restaurant is in the interval (24%, 38%) . There are 112,483 people in the city.
What is the interval for the number of people who are likely to want this restaurant in their city?
Round to the nearest person.
Answer:
(26996, 42744)
Step-by-step explanation:
24% of 112,483 = 26,996
38% of 112,483 = 42,744
So the interval is (26996, 42744).
The interval for the number of people who are likely to want this restaurant in their city is (26996,42744) given that there are 112,483 people in the city and the percent of people who want a new restaurant is in the interval (24%, 38%). This is obtained by calculating the number of people corresponding to the percentages.
What is the required interval for the number of people?Given that, the percent of people who want a new restaurant is in the interval (24%, 38%) and there are 112,483 people in the city.
Thus, 24% of 112,483 = (24/100) × 112,483
=26,996
Similarly, 38% of 112,483 = (38/100) × 112,483
=42,744
The required interval for the number of people is (26996,42744).
Hence the interval for the number of people who are likely to want this restaurant in their city is (26996,42744) given that there are 112,483 people in the city and the percent of people who want a new restaurant is in the interval (24%, 38%).
