The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 80% of planted seeds will germinate. Suppose the manufacturer is correct. If 10 seeds planted with the fertilizer are randomly selected, what is the probability that more than 7 of them germinate
Answers
The Probability of that more than 7 of them germinate is 0.2948.
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.We are to determine the probability that more than 7 of 10 seeds (i.e. 8, 0r 9 0r 10) germinate.
The probability that all 10 seeds germinate is equal 0.80¹⁰= 0.1073 = 10.73%.
The probability that only the first (only the second, etc ) seed does not germinate is equal 0.20 X 0.80⁹= 0.0268 = 2.68%.
The probability that 6 seeds germinate is the sum of the probabilities that only the first seed does not germinate, only the second one does not germinate, etc, and equals to 10 X 0.0268 = 0.268 = 26.8%.
The total probability that more than 7 of 10 seeds germinate is the sum of the probabilities that 10 seeds germinate and that 7 seeds germinate, i.e. 2.68 % + 26.8 % = 29.48 %.
Thus, The Probability of that more than 7 of them germinate is 0.2948.

Given the coordinates of quadrilateral JKLM as:
J(-2,3)K(3,7)L(6,5)M(1,1)Use the distance formula, [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex], to find each segment of the quadrilateral .
JK = √[(3−(−2))² + (7−3)²]
JK = √41
JK ≈ 6.4 units
KL = √[(3−6)² + (7−5)²]

Dave loves underwater diving. His house boat is 250 feet above sea level. He jumped from that level. He went 600 feet below sea level. How many feet did Dave go under the water?
Answers
Answer:
600 feetStep-by-step explanation:
I would just like to explain how this works with a visual (please enjoy my drawing <3 haha)
With my drawing we know that the bird is 150 feet above sea level, and the fish is 100 feet below sea level.
From the bird to the water it is 150 feet, from water to fish is 100 feet
From the bird to the fish it is 150 feet + 100 feet
This is equal to 250 feet,so we know from the bird (150 feet above sea level) to the fish(100 feet below sea level).
Knowing this information we can easily answer this questionDave is 250 feet above sea level, and he went 600 feet nelow sea level, meaning he only went 600 feet under the water.
A paper plate has a diameter of 9 inches. What measure is closest to the area of the plate?

The formula for the area of a circle is πr^2
r (Radius) is half of the diameter
r = 9/2
r = 4.5in
π x 4.5^2=
π x 20.25 = 63.6172512352
to 2 dp: 63.62 inches squared.
Answer:
The area of a plate with a diameter of 9 is 63.585
Step-by-step explanation:
A = πr² use 3.14 as pi
r = [tex]\frac{1}{2}[/tex] d
[tex]\frac{1}{2}[/tex] × 9 = 4.5
r = 4.5
A = 3.14 × 4.5²

17 students and 15 teachers went on a field trip to an art museum. student tickets cost $10 each, and adult tickets cost $12 each. How much did the museum tickets cost in all?
Answers
Answer:
350 dollars
Step-by-step explanation:
We're given:
17 students15 teachersStudent ticket = 10 dollarsAdult ticket = 12 dollarsFirst, find the total cost for student tickets:
17 students × 10 dollars = 170 dollarsTherefore, the total cost for student tickets was 170 dollars.
Now, find the total cost for adult tickets:
15 teachers × 12 dollars = 180 dollarsTherefore, the total cost for adult tickets was 180 dollars
To find the total cost for the museum tickets, find the sum:
180 + 170 = 350 dollars
Therefore, the museum tickets cost 350 dollars in total.

A class has 45 students. Each student has either 5 dollars or 2 dollars. Which Which situation results in the class having an average of 3 dollars per student
Answers
Step-by-step explanation:
an average of $3 per student would mean
sum(all students $) / 45 = 3
sum(all students $) = 3×45 = 135
x students have $5.
therefore (45-x) students have $2.
5x + 2(45-x) = 135
5x + 90 - 2x = 135
3x = 45
x = 15
so, 15 students have $5, and 45-15 = 30 students have $2.

It is a symbol used to denote an angle (or something else)
Step-by-step explanation:
Alpha(α) is a greek letter, it's one of the letters used to denote angles. Other such letters you'll often see in math are Beta (β), Gamma (γ), Delta (δ), these are used to denote angles. Also, pi (π), which is a mathematical constant. The letters phi (φ) and theta (θ) are also used for angles very often, especially in formulas. You'll see some of these in physics too.
It can be used as variable too, not necessarily for angles, but it's mostly used for them.
Find the sum of the first 200 terms of the arithmetic sequence that begins: 12, 18, 24, ...
Answers
Answer:
S₂₀₀ = 121800
Step-by-step explanation:
the sum to n term of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 12 and d = a₂ - a₁ = 18 - 12 = 6 , then
S₂₀₀ = [tex]\frac{200}{2}[/tex] [ (2 × 12) + (199 × 6) ]
= 100(24 + 1194)
= 100 ×1218
= 121800
