The general equation for exponential growth can be written as:
x_{t} = x_{0} (1+r)^{t}
where r is the growth rate.
Plugging in the given values, we get:
1100=1000(1+r)^{3}
Therefore
(1+r)^{3}=1.1
giving
1+r= \sqrt[3]{1.1} =1.0323
The predicted number of bacteria after 17 hours is given by:
1000(1.0323)^{17}=1716

Let X be a random variable representing the mean gray scale of each pixel.
P(110 ≤ X ≤ 140) = P(X < 140) - P(X < 110) = P(z < (140 - 125)/15) - P(z < (110 - 125)/15) = P(z < 1) - P(z < -1) = P(z < 1) - [1 - P(z < 1)] = 2P(z < 1) - 1 = 2(0.84134) - 1 = 1.68268 - 1 = 0.68268

Number of pixels that have gray scale of between 110 and 140 = 0.68268 x 1000000 = 682680 = approximately 680,000

White raven [17]
Spinning the first and second spinner will give 5 and 7 outcomes, respectively. To determine the total combinations or total outcome if these two are spun, use the <em>Fundamental Principles of Counting</em>. The total outcome is the product of the two outcomes. Thus, the answer is 35.

A rectangular field is 115 meters long and 70 meters wide. Give the length and width of another rectangular field that has the s
Sonbull [250]

Answer:

Length 100 m, width 85 m.

Step-by-step explanation:

If the perimeters are equal then the  sum width + length has to be the same as 70 + 115  = 185.

The area of the given field  = 115 * 70 = 8050 m^2.

Lets try  length 100 and width 85 .This gives an area of 8500 so that would fit.

hope this helped pls see the comment i gave to u about my question help a friend thx :)
