Answer:

your question was not understandable but I think I understand what you wanted to ask (hopefully)

providing that the die is not loaded, the probability is 1/6

if instead you refer to the results then it is 1/5 as 10/50 = 1/5 in this case it's a matter of statistics, not probability, probability is used to estimate something that has not yet happened

Step-by-step explanation:

laws that can be applied to big numbers cannot be applied to small numbers

e.g. if you roll a die 10 times and you get nine times 5, you cannot say the die is loaded, if you roll it 1000 times and you get 990 times 5, then there is a high probability that it's a loaded die

Darius counted that he walks 864 steps from his house to the bookstore. If Darius takes 52 steps each minute, about how long wil

MakcuM [25]

Answer:

It would take him approximately 16.62 minutes to reach the bookstore

Step-by-step explanation:

Total steps to the bookstore=Number of steps per minute×number of minutes

where;

Total steps to the bookstore=864 steps

Number of steps per minute=52

Number of minutes=t

Replacing;

864=52×t

t=864/52

t=16.62 minutes

It would take him approximately 16.62 minutes to reach the bookstore

Two jet planes simultaneously started travelling in opposite directions from the same airport. Four hours later they were 3800 m

alexira [117]

Answer:

Step-by-step explanation:

let the speed of one plane=x

speed of other plane=x+80

time=4 hrs

then 4x+4(x+80)=3800

4x+4x+320=3800

8x=3800-320

or 8x=3480

x=435

speed of one plane=435 m/h

speed of other plane=435+80=515 m/h

Let he walks x hrs

then he take a taxi for 2-x hrs

4x+(2-x)50=31

4x+100-50x=31

-46x=-69

$x=\frac{-69}{-46}=\frac{3}{2}$

so he walks 3/2 hrs=1.5 hrs

travels by taxi=2-1.5=0.5 hrs

distance traveled by taxi=0.5×50=25 miles

Which equation using x to represent time best represents the floor number of an elevator descending at a steady rate?

zepelin [54]

C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.
