What is the estimate of 872 times 3

1 answer:

8 0

To estimate the answer of 872*3 we know that 872 is only 28 away from 900 so we'll round 872 up to 900. Then we can take 900*3 which is 2,700. So we now know that 872*3 is roughly 2,700.

Hope this helps!=)

City A is 25% less than population of city B so city A's population is what % of city B

Lerok [7]

City A is 25% less than population of city B. So city A's population is 75% of city B

<h3><u>Solution:</u></h3>

Given that City A is 25% less than population of city B

To find: city A's population is what % of city B

From given information,

City A is 25% less than population of city B

A = B - 25% of B

So we can write as,

$A = B - \frac{25}{100} \times B\\\\A = B - 0.25B\\\\A = 0.75B$

A = 0.75B can be written as,

$A = \frac{75}{100}\times B$

city A = 75 % of City B

Thus city A's population is 75% of city B

natita [175]

Answer:

See below

Step-by-step explanation:

<h3>Continuation of the question</h3>

<u>Data in the table:</u>

<u>Bacteria 116 120 131 136 141 151 148 163</u>

<em>Create a scatter plot to represent the data: Based on the data and your scatter plot, what do you think a good linear function would be to represent the data?</em>

<h3>Solution</h3>

<em>See attached for scatter plot</em>

We can see the chart is close to linear function. Let's build one based on data in the table

y = mx + b

<u>If we use two points and get the equation</u>

(4, 116) and (8, 141)

<u>Finding the slope:</u>

m = (141-116)/(8-4) = 25/4 = 6.25

<u>Then, finding y-intercept:</u>

116 = 6.25*4 + b
b = 116 - 25 = 91

y = 6.25x + 91

<em>Note: This is approximate best fit graph and it is attached as well. Exact formula for the line is built by using different method and is very close to the one above</em>
