Answer:

The diagonal is 30 inches

step-by-step explanation:

The diagonal is 30 inches

Step-by-step explanation:

Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this

a² + b² = c²

so we plug our two values to find the diagonal (hypotenuse)

24² + 18² = c²

576 + 324 = c²

900 = c²

c = √900

c = 30

The diagonal is 30 inches

Answer:

1,79,07,120  ways

Step-by-step explanation:

Ways in which 3 solids can be chosen from 19 solids = 19 c 3

33 striped prints can be chosen from 99 striped prints in 9 c 3 ways

33 floral prints can be chosen from 121 floral prints in 12 c 33 ways

So, total ways = (19 c 3) (9 c 3) (12 c 3)

(969) (84) (220)

Answer:

SELECT distinct(TRUCK_ID), WEIGHT from SHIPMENT where WEIGHT < 800 ;

Step-by-step explanation:

The Structured query language (SQL) defined above, returns only the TRUCK_ID and Weight column from the shipment table as they are the only two columns listed after the select keyword. The condition is added using the WHERE keyword on the weight table, this filters the result returned to include only rows where the weight value is less than 800. The distinct keyword used alongside the TRUCK_ID column ensures that a certian TRUCK_ID value isn't returned more than once (Hence, it is used to avoid duplicates).

Answer:

D. $13.76 million is the correct answer :)

Step-by-step explanation:

The solution is, $13.76 was the predicted profit in year 10.

Here, we have,

Given : the equation is,

y=-0.34x^2 + 4.43x + 3.46.

To Find : Using the quadratic regression equation, what was the predicted profit in year 8

Solution :

y=-0.34x^2 + 4.43x + 3.46.

Where y is profit and x is year

Substitute x = 10

y=-0.34* 10^2 + 4.43*10+ 3.46.

or, y = 13.76

So, Option D is true

Hence the predicted profit in year 10 is $13.76.

Step-by-step explanation:

Given:

Selling price of each CD = $5.00

Cost price of each CD = $1.25

Number of CDs ordered = 300

Profit must be at least $500.

To find:

The number of CDs needs to sell.

Solution:

Let n be the number of CDs needs to sell.

Selling price of each CD = $5.00

Selling price of x CDs = $5n

Cost price of each CD = $1.25

Cost price of 300 CDs = 300×$1.25

                                      = $375

We know that,

[tex]Profit=S.P.-C.P.[/tex]

[tex]Profit=5n-375[/tex]

Profit must be at least $500. it means profit must be greater than or equal to $500.

[tex]5n-375\geq 500[/tex]

[tex]5n\geq 500+375[/tex]

[tex]n\geq \dfrac{875}{5}[/tex]

[tex]n\geq 175[/tex]

All options are incorrect. The required inequality is n is greater than or equal to 175.

Answer:

Step-by-step explanation:

Because angles A and B are the same, line segments AB and BC are the same.  This means you can use the same variable for both in the Pythagorean theorem.

x²+x²=20²

x²=200

x=√200

x=14.1421356237

Answer:

x = 10[tex]\sqrt{2}[/tex]

Step-by-step explanation:

this is a 45-45-90° Δ and the leg to hypotenuse ratio is always 1 : [tex]\sqrt{2}[/tex]

so we can set up a proportion:

20 / [tex]\sqrt{2}[/tex] = x / 1

cross-multiply:

[tex]\sqrt{2}[/tex]x = 20

x = 20 / [tex]\sqrt{2}[/tex], which simplifies to 10[tex]\sqrt{2}[/tex] if you rationalize the denominator

Because there are lengths going from 0 to 1, the lines must mean either decimals or fractions (we'll use fractions for this.)

1. There are twelve lines from 0 and 1, which we can use as the denominator for our fraction. This means the length of each line is 1/12.

2. In order to find where K's point is at, we simply need to count until we get to it. After counting, I see that K is on point 8/12, which we can simplify to get a smaller number. If we simplify once, we get 4/6, which we can again simplify to get 2/3. This gives us the answer K is on point 8/12 or 2/3.

The expression (7/8) x (4/7) simplified to its simplest form is 1/2.

To simplify the expression (7/8) x (4/7), you can multiply the numerators together and the denominators together, and then simplify the resulting fraction if possible.

(7/8) x (4/7)

= (7 x 4) / (8 x 7)

= 28 / 56

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 28:

28 / 56

= (28 ÷ 28) / (56 ÷ 28)

= 1 / 2

Therefore, (7/8) x (4/7) simplified to its simplest form is 1/2.

Answer:

a) 0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.

b) 0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.

c) 0.064 = 6.4% probability that 7 of them are discovered.

Step-by-step explanation:

For itens a and b, we use conditional probability.

For item c, we use the binomial distribution along with the conditional probability.

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

a) If it has an emergency locator, what is the probability that it will not be discovered?

Event A: Has an emergency locator

Event B: Not located.

Probability of having an emergency locator:

66% of 72%(Are discovered).

20% of 100 - 72 = 28%(not discovered). So

[tex]P(A) = 0.66*0.72 + 0.2*0.28 = 0.5312[/tex]

Probability of having an emergency locator and not being discovered:

20% of 28%. So

[tex]P(A cap B) = 0.2*0.28 = 0.056[/tex]

Probability:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.056}{0.5312} = 0.105[/tex]

0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.

b) If it does not have an emergency locator, what is the probability that it will be discovered?

Probability of not having an emergency locator:

0.5312 of having. So

[tex]P(A) = 1 - 0.5312 = 0.4688[/tex]

Probability of not having an emergency locator and being discovered:

34% of 72%. So

[tex]P(A \cap B) = 0.34*0.72 = 0.2448[/tex]

Probability:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2448}{0.4688} = 0.522[/tex]

0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.

c) If we consider 10 light aircraft that disappeared in flight with an emergency recorder, what is the probability that 7 of them are discovered?

p is the probability of being discovered with the emergency recorder:

0.5312 probability of having the emergency recorder.

Probability of having the emergency recorder and being located:

66% of 72%. So

[tex]P(A \cap B) = 0.66*0.72 = 0.4752[/tex]

Probability of being discovered, given that it has the emergency recorder:

[tex]p = P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.4752}{0.5312} = 0.8946[/tex]

This question asks for P(X = 7) when [tex]n = 10[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 7) = C_{10,7}.(0.8946)^{7}.(0.1054)^{3} = 0.064[/tex]

0.064 = 6.4% probability that 7 of them are discovered.
