Question 3
The population of a sample of bacteria triples every minute. If the initial population of the sample is 2 bacteria, Nicholas believes
the equation p-2(3)' can be used to find the total population after t minutes,
=
Is Nicholas correct? If not, why not?
a.No, Nicholas switched the initial population and the rate. The equation should be P - 3(2)'
b.No, Nicholas should have wrrtten a linear equation. The equation should be P - 2+ 31
c.Yes, Nicholas is correct.

Answer:

=30x

=10x

Step-by-step explanation:

7x + 23 = 30x

21x - 11 = 10x

Answer:

A

Step-by-step explanation:

The slope in a slope-intercept equation is the coefficient of x.

In A, the slope is a 4/3, which is positive

In B, the slope is a -5, which is negative

Answer:

y=3x-2

Step-by-step explanation:

We know the equation ends in -2 because when x is zero, y is -2

To find the rest of the equation take any other point and take away the -2 from y

Then divide the y by the x to see how may times larger (or smaller) the y is then the x

(I chose -14)

-12÷-4=3

y=3x

the put the -2 back at the end because otherwise, your -14 would be a -12 and that is not a point on the table

This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.

Answer:

length = 15   width = 8  

Area 15x8 = 120

Step-by-step explanation:

L = length

W= width

L = W + 7 (width plus7)

Area = W x L

Area =W (W+7)    

Do the distribution:

120 = W ² +  7W

Subtract 120 on both sides

    W + 7W -120 = 0

           Factor it

    (W + 15)(W - 8) = 0

    W = -15 or W = 8

              8 is used  for W

              L = W + 7

         L =  8+7=15  

Length = 15

Width =8.

Answer and Step-by-step explanation:

We have to use the image to help us answer this question.

We see that there are 8 big fish in the tank, and 10 small fish in the tank.

So, for the first part, it would be:

There are 8 big fish for every 10 small fish.

For when there are 4 big fish, we need to divide 10 by 2, since 8 divided by 2 is 4.

10 ÷ 2 = 5

So,

There are 4 big fish for every 5 small fish.

I hope this helps!!

Angle AGC

Step-by-step explanation:

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary

Answer:

The area between the curves is 4 square units.

Step-by-step explanation:

We want to find the area bounded by:

y = x

x = 0

in the interval x = 1, x = 3

This is simply equal to the integral of the function f(x) = x between x = 1 and x = 3

Written as:

[tex]\int\limits^3_1 {x} \, dx[/tex]

And the integral of x is equal to x^2/2

Then:

[tex]\int\limits^3_1 {x} \, dx = (\frac{3^2}{2} - \frac{1^2}{2}) = (\frac{9}{2} - \frac{1}{2} ) = \frac{8}{2} = 4[/tex]

The area between the curves is 4 square units.

Answer:

- 2

Step-by-step explanation:

Given that :

Population mean, μ = 11

Population standard deviation, σ = 2

Sample mean, xbar = 9

Sample size, n = 16

The sampling error could be explained as the variation or difference which exists in statistical measure of the population and sample as the sample data does not totally or wholly represent the population data. This difference in sample and population mean is called sampling error.

Hence, the sampling error in the above scenario can be obtained thus :

Sampling error = (xbar - μ)

Sampling error = 9 - 11 = - 2

Answer:

31 inches squared

Step-by-step explanation:

Area of shaded part = area of square - area of circle

area of square = length²

12² = 144

Area of a circle = πr²

r = radius = 12/2 = 6

(3.14) x 6² = 113.04

Area of shaded part = 144 - 113.04 = 30.96

rounding off to the nearest whole number gives 31

31 squared inches
