If a scientific team uses special equipment to measures the pressure under water and finds it to be 282 pounds per square foot, at what depth is the team making their measurements?

Answers

p=282 pounds per square foot =1 376.8 kg/m2

d- density of water

d≈997 kg/m³

p=d*h

h=p/d

h=1 376.8/997

h=1.38 m (about 4530 feet 105⁄64 inches)



The probability of a head is 0.27. The coin is thrown 200 times. Write an

estimate for the amount of tails

Answers

Answer:

The estimate for the amount of tails is 146.

Step-by-step explanation:

For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The probability of a head is 0.27.

This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]

The coin is thrown 200 times.

This means that [tex]n = 200[/tex]

Write an estimate for the amount of tails

This is the expected value, so:

[tex]E(X) = np = 200*0.73 = 146[/tex]

The estimate for the amount of tails is 146.

1. Is a triangle with side lengths 6, 4, 3 a right triangle? Why or why
not?

Answers

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 6 , then 6² = 36

4² + 3² = 16 + 9 = 25

Since 4² + 3² ≠ 6² then triangle is not right.

Carmine is in both groups of students.
What is the total number of mini muffins Carmine gets?
Carmine gets
muffins.

Answers

Step-by-step explanation:

oatmeal 12/8 = 1.5 per student

apple 27/6 = 4.5 per student

carmine gets 1.5 + 4.5 = 6 muffins

Answer:

Step-by-step explanation:

(12 oatmeal)/(8 students) = (1.5 oatmeal)/student

Each student gets 1.5 oatmeal muffins.

(27 apple)/(6 students) = (4.5 apple)/student

Each student gets 4.5 apple muffins.

Carmine gets 1.5 oatmeal plus 4.5 apple = 6 muffins

find y and round to the nearest tenth. thank you

Answers

Answer and Step-by-step explanation:

31 degrees on the top would be equal to the angle in between x and 600ft, by the interior angles theorem.

That means we can solve for y using the trigonometric function of tangent.

[tex]tan(31) = \frac{y}{600}[/tex]

Multiply by 600 to both sides, then use a calculator to solve.

600(tan(31)) = x

x = 360.5163714

x ≈ 360.5 is the answer.

A contractor is required by a county planning department to submit one, two, three, four, five, six, or seven forms (depending on the nature of the project) in applying for a building permit. Let Y = the number of forms required of the next applicant. The probability that y forms are required is known to be proportional to y—that is, p(y) = ky for y = 1, , 7.
A) What is the value of c?
B) What is the probability that at most three forms are required?
C) What is the probability that between two and four forms (inclusive) are required?
D) Could pX(x) = x^2/50 for x = 1, . . . , 5 be a probability distribution of X? Explain.

Answers

Answer:

Step-by-step explanation:

Given that:

P(Y) = ky

where;

y =1,2,...7

To find the value of c or k (constant)

[tex]\sum P(Y) = 1[/tex]

[tex]\sum \limits_{y \to 1}^7 k*y = 1[/tex]

= k(1+2+3+4+5+6+7) = 1

28k = 1

[tex]k = \dfrac{1}{28}[/tex]

b) The required probability is P ( X ≤ 3)

[tex]P(X \le 3) = \sum \limits^3_{y=1 } P(y)[/tex]

[tex]P(X \le 3) = \sum \limits^3_{y=1 } \dfrac{1}{28}(y)[/tex]

[tex]P(X \le 3) = \dfrac{1}{28} (1 +2+3)[/tex]

[tex]P(X \le 3) = \dfrac{6}{28}[/tex]

P ( X ≤ 3) = 0.2143

c) The required probability P(2 ≤ Y ≤ 4)

[tex]P(2 \le Y \le 4) = \sum \limits ^4_{y=2} P(Y)[/tex]

[tex]P(2 \le Y \le 4) = \sum \limits ^4_{y=2} \dfrac{1}{28}(Y)[/tex]

[tex]P(2 \le Y \le 4) = \dfrac{1}{28}(2+3+4)[/tex]

[tex]P(2 \le Y \le 4) = 0.3214[/tex]

d) The required probability:

[tex]P(X) = \dfrac{x^2}{50} ; \ \ \ \ where; \ x= 1,2,...5[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)= \sum \limits ^5_{y =1} \dfrac{1}{50}(x)^2[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)= \sum \limits ^5_{y =1} \dfrac{1}{50}(1+4+9+16+25)[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)=1.1[/tex]

3. Number of pets living in a household is a discrete variable.

A continuous variable is one that we can get the value through measurements.
