James read 4 pages in a book in 6 minutes. How long would it take him to read 6 pages

2 answers:

8 0

This is probably directly proportional
disregarding other factors such as eyestrain, fires, and apocalypses.
4:6
treat as fraction
4/6=2/3
how long to read 6
6/x=2/3
multiply 2/3 by 3/3 since 2 times 3=6
6/x=6/8
x=8

60X6=360 seconds, 360 divided by 4= 90, James takes 90 seconds to read one page. 90X6=540, 540divided by 60 is 9. James takes 9 minutes to read 6 pages.

QUESTION 1 The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.Assume that the driving

GarryVolchara [31]

Answer:

$P(X>300)$

And we can find this probability with the complement rule:

$P(X>300)= 1-P(X$

Step-by-step explanation:

For this case we define the random variable X ="driving distance for the top 100 golfers on the PGA tour" and we know that:

$X \sim Unif (a=284.7, b=310.6)$

And for this case the probability density function is given by:

$f(x) =\frac{1}{310.6 -284.7} =0.0386 , 284.7 \leq X \leq 310.6$

And the cumulative distribution function is given by:

$F(x) =\frac{x-284.7}{310.6-284.7} , 284.7 \leq X \leq 310.6$

And we want to find this probability:

$P(X>300)$

And we can find this probability with the complement rule:

$P(X>300)= 1-P(X$

25m/s to miles/h <br>Can anyone solve it?<br>With explanation if you can

Dimas [21]

25 meters per second x 60 seconds = 1500 meters per minute

1500 meters per minute x 60 minutes per hour = 90,000 meters per hour

1 mile = 1609.34 meters

90000/1609.34 = 55.92 miles per hour

round answer to either 55.9 or 56 mph depending on what you need.

$\bf \textit{"The distance around each dot is 24}\pi \textit{ inches."}\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\quad 
\begin{cases}
r=radius\\
-----\\
C=24\pi 
\end{cases}\implies 24\pi =2\pi r\implies \cfrac{24\pi }{2\pi }=r
