The only true statement in the following equation are B and D.

A. When the bacteria population reaches 900, 12 hours have passed since the colony was placed on the petri dish.

To check this statement, we can use the formula for exponential growth:

P(t) = P0 * [tex]3^{(t/6)[/tex]

Where P(t) is the population at time t, P0 is the initial population, and t is the time in hours.

If P(t) = 900, we can solve for t:

900 = [tex]100 * 3^{(t/6)[/tex]

9 = [tex]3^{(t/6)[/tex]

ln(9) = (t/6) * ln(3)

t = 6 * ln(9) / ln(3) ≈ 12.68

So, it takes approximately 12.68 hours for the population to reach 900. Therefore, statement A is false.

B. Three hours after the colony is placed on the petri dish, there are 200 bacteria.

Using the formula above with t=3:

P(3) = [tex]100 * 3^{(3/6) = 200[/tex]

So, statement B is true.

C. Three hours after the colony is placed on the petri dish, there are about 173 bacteria in the colony.

Using the formula above with t=3:

P(3) = [tex]100 * 3^{(3/6) = 200[/tex]

So, statement C is false.

D. In the first hour the colony is placed on the petri dish, the population grows by a factor of [tex]$3^{\frac{1}{6}}$[/tex]

Using the formula above with t=1:

P(1) = [tex]100 * 3^(1/6)[/tex]

So, the population after 1 hour is 100 times the sixth root of 3. We can write this as:

P(1) = [tex]100 * (3^(1/6)) = 100 * 3^{\frac{1}{6}}[/tex]

Therefore, statement D is true.

E. Between 8 a.m. and 9 a.m., the population grows by a factor of [tex]$3^{\frac{2}{3}}$[/tex]

Between 7 a.m. and 8 a.m., the population grows by a factor of 3. Then, between 8 a.m. and 9 a.m., it grows by another factor of 3. So, between 7 a.m. and 9 a.m., the population grows by a factor of [tex]3^2[/tex] = 9. Taking the sixth root of 9 gives:

[tex](3^2)^(1/6) = 3^(1/3) = 3^{\frac{2}{6}} = 3^{\frac{1}{3}}[/tex]

So, the population between 8 a.m. and 9 a.m. grows by a factor of [tex]3^(1/3)[/tex]. Therefore, statement E is false.

In summary, the true statements are B and D.

We can employ the AC approach to factor the quadratic expression seen in the image. To achieve -6 * -15 = 90, we first multiply the coefficients of the first and last terms. The middle term's coefficient, which is -9, is then shown to be two factors of 90. Since -6 * -15 = 90 and -6 + (-15) = -21, which is the same as -9 when we factor out the GCF of 3, these factors are -6 and -15:

[tex]x^2 - 9x - 90 = (x - 15)(x + 6)[/tex]

As a result, the quadratic expression's factored form is (x - 15)(x + 6).

Stockton lake lost the least amount of water.

What is Denominator?

In mathematics, the denominator is the bottom number in a fraction that indicates the number of equal parts into which a whole is divided.

To compare the amount of water lost by each lake, we need to express the amounts lost in the same units. One way to do this is to find a common denominator for the fractions and percentages involved.

Lake Jensen lost 5/6 of its water, which can be expressed as a fraction with a common denominator of 300:

5/6 = 250/300

Lake Parlow lost 85% of its water, which can be expressed as a fraction with a denominator of 100:

85% = 85/100 = 255/300

Lake Stockton lost 246/300 of its water, which is already in terms of a common denominator of 300.

Now we can compare the amounts lost directly:

Lake Jensen lost 250/300 of its water

Lake Parlow lost 255/300 of its water

Lake Stockton lost 246/300 of its water

To determine which lake lost the least amount of water, we need to find the smallest fraction among these three.

We can see that Lake Stockton lost the least amount of water, since 246/300 is smaller than both 250/300 and 255/300. Therefore, Lake Stockton lost the least amount of water.

The b is the y intercept.  This is where the graph crosses the y axis.  Graph this first.  The m is the slope.  It is the rise over the run.  You can make any number a fraction by putting it over 1.  From the y-intercept you use the slope (rise/run) to graph the second point.  

For example, if the slope is 1. then 1/1 would show your rise and run. Start when the y-intercept is and go up 1 and then 1 right.  Connect the two points that you have graphed.

If the slope is 2/7, then from the y-intercept go up 2 and right 7.  Graph that point and draw a line connecting that point to the point on the y-intercept.

Hence, in response to the provided question, we can say that As a result,  function the discus takes approximately 0.03125 seconds to strike the ground.

Mathematicians research numbers and their variants, equation and related structures, objects and their locations, and prospective locations for these things. The term "module" is used to describe the connection that exists in between set of inputs, each of which has a corresponding output. A function is an input-output connection in which each inputs results in something like a single, distinct return. A domain, codomain, or scope is assigned to each function. Functions are usually denoted by the letter f. (x). An x is used for entry. On capabilities, one-to-one capabilities, multiple prowess, in capabilities, and on capabilities are the four major types of accessible functions.

The supplied function for discus height is as follows:

[tex]h(t) = -16t^2 + 38t + 5\\h(0) = -16(0)^2 + 38(0) + 5 = 5[/tex]

As a result, the discus's starting height is 5 feet.

[tex]-16t^2 + 38t + 5 = 0\\[/tex]

To find t, we can apply the quadratic formula:

t = (-b \sqrt(b2 - 4ac)) (2a)

where a=-16, b=38, and c=5.

[tex]t = (-38 + \sqrt(38^2 - 4(-16)(5))) / (2(-16))\\t = (-38 + \sqrt(1524)) / (-32) (-32)\\t = (-38 + 39) / (-32) (-32)\\[/tex]

As a result, [tex]t = (-38 + 39) / (32) or t = (-38 - 39) / (32) (-32)[/tex]

t = 1/32 or t = 77/32

As the negative value doesn't make sense in this situation, we chose the positive value:

t = 1/32

The probability that at least 29% of the sample are from poverty-level households is 0.17% and we do not have enough evidence to reject the null hypothesis that the population proportion is equal to 22%.

According to government data, 22% of American children under the age of 6 live in households with incomes less than the official poverty level. A study of learning in early childhood chooses an SRS of 300 children from one state and finds that at least 29% of the sample are from poverty-level households.

To answer part (a) of the question, we can use the normal approximation to the binomial distribution. The mean of the distribution is np = 300 * 0.22 = 66 and the standard deviation is sqrt(np(1-p)) = sqrt(66 * 0.78) = 7.09. We can use the normalcdf function to find the probability that at least 29% of the sample are from poverty-level households:

normalcdf(87.5, 300, 66, 7.09) = 0.0017

So the probability is 0.17%.

For part (b) of the question, we need to determine if there is convincing evidence that the percentage of children under the age of 6 living in households with incomes less than the official poverty level in this state is greater than the national value of 22%.

Since the probability that at least 29% of the sample are from poverty-level households is 0.17%, which is very small, we can conclude that there is not convincing evidence that the percentage of children under the age of 6 living in households with incomes less than the official poverty level in this state is greater than the national value of 22%.

The small probability suggests that the observed sample result is unlikely to occur by chance if the true population proportion is 22%, so we do not have enough evidence to reject the null hypothesis that the population proportion is equal to 22%.

The greatest possible difference between David's result and Armen's result is 5.

Let's first consider the maximum number of odd shirts Armen can count. Since there are only 5 odd numbers between 1 and 9, the maximum number of odd shirts Armen can count is 1+3+5+7+9 = 25.

Now, let's consider the maximum number of even shirts David can count. Since there are only 4 even numbers between 1 and 9, the maximum number of even shirts David can count is 2+4+6+8 = 20.

Therefore, the greatest possible difference between David's result and Armen's result is

= 25 - 20

Subtract the numbers

If the bottle can only hold 13 ounces, then the probability the bottle will overflow is approximately 0.0032 or 0.32%.

First, we need to calculate the z-score, which is the number of standard deviations that the mean value of 12.2 ounces is away from the bottle's capacity of 13 ounces. We can calculate the z-score using the formula:

z = (x - μ) / σ

where x is the bottle capacity (13 ounces), μ is the mean value of soda dispensed by the machine (12.2 ounces), and σ is the standard deviation (0.3 ounces).

Substituting the values, we get:

z = (13 - 12.2) / 0.3 = 2.67

The z-score of 2.67 means that the bottle capacity of 13 ounces is 2.67 standard deviations away from the mean value of soda dispensed by the machine.

Substituting the values, we get:

P(Z > 2.67) = 1 - P(Z ≤ 2.67) = 1 - 0.9968 = 0.0032

Therefore, the probability of the soda bottle overflowing is approximately 0.0032 or 0.32%.
