Answer:
The answer is option 1.
Step-by-step explanation:
You have to cube root to both sides in order to find p :
[tex] {p}^{3} = 8[/tex]
[tex] \sqrt[3]{ {p}^{3} } = \sqrt[3]{8} [/tex]
[tex]p = \sqrt[3]{8} [/tex]
Write the intersection and union of N and W.
N being the definition of a Natural Number {1,2,3,4} and W being Whole numbers {0,1,2,3,4}
Answer:
N n W = {1,2,3,4}
N u W = {0,1,2,3,4,}
Step-by-step explanation:
N n W = {1,2,3,4}
N u W = {0,1,2,3,4,}
n - intersection means the common elements between N and W
U - represents all elements within N and W
The sum of four consecutive integers is -10. What are the integer
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
Write the equation in standard form and then find the center (h, k) and
x^2+8x+ y2 + 4y - 5= 0
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.

A plane is flying at an altitude of 13,100 ft. The angle of depression from the plane to a control tower is 12º. What is the horizontal distance from the plane to the tower? Answer rounded to the nearest tenth of a foot.
Answer:
The horizontal distance from the plane to the tower is 2784.5 feet.
Step-by-step explanation:
From the given question, the height of the control tower is not given. But;
Tan θ = [tex]\frac{Opposite side}{Adjacent side}[/tex]
Tan [tex]12^{0}[/tex] = [tex]\frac{x}{13100}[/tex]
x = 13100 × Tan [tex]12^{0}[/tex]
= 2784.4910
Thus, x = 2784.5 feet
Therefore, the horizontal distance from the plane to the tower is 2784.5 feet.
Answer:
The horizontal distance from the plane to the control tower is 61630.7 ft.
Step-by-step explanation:
Here we have that
Height of flight of plane = 13,100 ft = Opposite side of angle of elevation
Angle of depression from the plane to the control tower = 12°
Therefore, the control tower can be sighted on a straight (hypotenuse) line from the plane with an angle of depression of 12°
Angle of depression from the plane to the control tower = Angle of elevation from the control tower to the plane = 12°
Horizontal distance from the plane to the control tower = Adjacent side of the hypotenuse of the right triangle = (Opposite side of angle of elevation) ÷ (Tangent of angle of elevation)
∴ Horizontal distance from the plane to the control tower = 13,100/(tan(12°)
Horizontal distance from the plane to the control tower = 61630.7 ft. to the nearest tenth of a foot.
Ty’s experimental probability of winning a certain game is 1/3. Jana’s expiremental probability of winning the same game is 3/4. If Ty and Jana each played the game 120 times, how many more games would Jana expect to win over Ty?
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.

What is the median number of carrots in a one-pound bag?
Answer:
To find the medium order the numbers from least to greatest. Then each time cross off one number from the left side and the right. When you get down to 1 or you have 2 left those are your medians. 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.

An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability that the spinner does not land on yellow. Express your answer as a fraction in simplest form.
Red = 12
Blue = 10
Yellow = 6
A. 11/14
B. 3/7
C. 4/7
D. 3/14
Answer:
A. 11/14
Step-by-step explanation:
i hope this helps :)
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.
What is the formula for the experimental probability?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.

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

Mr. Suárez wants to paint his storage shed. He needs to calculate the lateral surface area of the shed so that he will know how much paint to buy. The shed is in the shape of a rectangular prism with the dimensions shown below. Including the doors, what is the lateral surface area of the storage shed in square feet? 784 ft2 266 ft2 532 ft2 336 ft2
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

a man owned 75 shares of stock worth $50 each the corporation declared a dividend of 8% payable in stock how many shares did he then own
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

What are the solutions to this quadratic equation? x^2+6x-5=0
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]
