Answer:

y=-6x+8

Step-by-step explanation:

A literal equation is an equation where variables represent known values. Literal equations allow use to represent things like distance, time, interest, and slope as variables in an equation. Using variables instead of words

11 - y = 3 + 6x

-11 -y = 3 -11 +6x

----------------------------------------------------

0-y = -8 +6x

Multiply everything by -1

y= -6x=8

Someone solve these equations with working really appreciate it

Answer:

a) $t = \sqrt{\frac{d}{4.9} }$

b) t = 0.3 seconds

c) d = 4.9t²

d) d = 11 cm.

Step-by-step explanation:

One test involves catching a 1 m ruler and measuring the distance, d in meters, that the ruler will travel before being caught, the reaction time t in seconds is then calculated using the formula

$t = \sqrt{\frac{2d}{9.8} }$ .......... (1)

a) the simplified expression is

$t = \sqrt{\frac{d}{4.9} }$ ......... (2)

b) If d = 44 cm = 0.44 meters, from equation (2) we get,

t = 0.299 seconds ≈ 0.3 seconds (Approximate)

c) If we make d as the subject of the equation, then

$t^{2} = \frac{d}{4.9}$

⇒ d = 4.9t² .......... (3)

d) Now, if $t = \frac{0.3}{2} = 0.15$ seconds, then from equation (3) we get,

d = 4.9 (0.15)² = 0.11 meters = 11 cm (Answer)

What is the purpose of calculating a confidence interval? Multiple Choice To provide a range of values that has a certain large

Nadusha1986 [10]

Answer:

To provide a range of values that, with a certain measure of confidence, contains the population parameter of interest.

To provide a range of values that has a certain large probability of containing the population parameter of interest.

Step-by-step explanation:

For estimating a parameter value, it is important to know the statement or degree of confidence that the interval contains the parameter value along with knowing the point estimate and the amount of possible error in the point estimate (which is the interval likely to contain the parameter value).Thus , an interval estimate of a population parameter is the confidence interval with a statement of confidence that the interval contains the parameter value. The confidence interval is a range of values around the statistic that are believed to contain, with a certain probability (say 99%) the true value of that statistic or the population value.

How many minutes will it take each of them to arrive at the scene?

elixir [45]

Step-by-step explanation:

If you were to expand your research to include other genres, you'd find that most scenes in most movies are no more than three minutes long, which means no more than three pages of script. It's not an iron-clad rule; scenes can be twenty minutes long. But it's a very useful rule of thumb.
