bezimeni [28]

If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is μ<=80.

The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.

The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.

It always contains = , ≤ , ≥ signs.
The results will be examined using a one-tailed hypothesis test.

Hence, μ<=80

A charter airline finds that on its Saturday flights from Philadelphia to London, all 120 seats will be sold if the ticket price

Nataliya [291]

Answer:

a) $P=3(120-s)+200$

b) $215 \leq P \leq 290$

Step-by-step explanation:

For this case we can use a linear model to solve the problem.

s) Create an equation to express the increase on the price tickets and the number of seats sold

$s$ number of seats, if w analyze the info given the number of seats after increase the price is given by $120-s$ .

And let P the price for the ticket. So after the increase in ticket price the expression for the increase is P-200.

We have an additional info, for each increase of $3 the number of setas decrease 1. And the equation that gives to us the price change in terms of the increase of price is:

$P-200=3(120-s)$

So then our linear equation is given by:

$P=3(120-s)+200$

b) Over a certain period, the number of seats sold for this flight ranged between 90 and 115. What was the corresponding range of ticket prices?

So for this case we just need to replace the limits into the linear equation and see what we got:

$P_L=3(120-90)+200=290$

$P_U=3(120-115)+200=215$

So the corresponding range of ticket prices is:

$215 \leq P \leq 290$

The speed of light in a vacuum is 29,980,000,000

sweet [91]

Answer:

$\huge\boxed{\sf 2.998 \times 10^{10}}$

Step-by-step explanation:

Given number:

29,980,000,000

Rules:

Move the decimal point after the first non-zero digit. (after 2)
Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).

The number will become:

2.998 × 10¹⁰

$\rule[225]{225}{2}$
