Answer:

104.17 hours.

Step-by-step explanation:

We have been given that Samuel can type nearly 40 words per minute. We are asked to find time taken by Samuel to type 2.5\times 10^{5} words.

To find number of hours, we will divide 2.5\times 10^{5} by 40 as:

\frac{2.5\times 10^{5}}{40}

\frac{2.5\times 10^{5}}{4\times 10}

\frac{2.5\times 100000}{40}

\frac{250,000}{40}

6250

Now, we will convert 6250 minutes to hours by dividing 6250 by 60 as 1 hour equals 60 minutes.

\frac{6250}{60}=104.166\approx 104.17

Therefore, it will take 104.17 hours to type the given words.

10 to the 5th power is 100,000.

So, 2.5 x 100,000 = 250,000

Since Samuel can type 40 words per minute, do 250,000 ÷ 40 = 6250

Since there are 60 minutes in an hour and Samuel types 40 words per minute, multiply 40 x 60 until you get close to 6250.

Enter an equation in point-slope form for the line.<br> Slope is 9 and (−3, −1) is on the line.
Korolek [52]

Answer:

y+1=9(x+3)

Step-by-step explanation:

Since the equation for point slope form is y-y₁=m(x-x₁)

enter the given points (-3,-1)

y-(-1)=9(x-(-3))

y+1=9(x+3)           <-- point slope form

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 16 years; the
STatiana [176]

Using the Emperical rule:

68% lie with one one standard deviation:

16 + 1.7 , 16-1.7 = 17.7, 14.3

14.3 is part of the 68%.

The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.

32/2 = 16

The probability of living loner than 14.3 Would be 16%
