Solve for x in each set of parentheses by setting them to 0:
X -8 = 0
X = 8
X+9 = 0
X =-9
You have two x intercepts (8,0) and (-9,0)
You didn’t list any choices to pick from but it would be either if the ones above.
The estimated population, if the rate is a growth rate is 34696 populations
The estimated population, if the rate is a decline rate is 5657 populations
<h3> Exponential functions</h3>
The standard exponential equation is expressed as 
where;
- a is the intercept
- b is the growth rate
- x is the time taken
If the initial population is 15,000 with a rate of 15%, then;
a) If the rate is a growth rate, the estimated population will be expressed as;
The estimated population, if the rate is a decline rate is 34696 populations
b) If the rate is a decline rate, the estimated population will be expressed as;
The estimated population, if the rate is a decline rate is 5657 populations

Answer: Population has a standard deviation of 32. What is the standard error f the sampling distribution if the sample size is 100?
Step-by-step explanation: Here we are told that a population has a standard deviation of 32 and that we have a sample of size 100 from this population that are asked for the standard error of the sampling distribution. Now it would be important to know what statistic we are taking from these samples. Now we would need to know what what statistic we're taking from these samples. Um I'm assuming that we're talking about sample averages in this case the standard error is well, let's sample averages are just distributed like this. They are so we have anna's big, which means that our sample averages are going to be approximately normally distributed. The mean of the sample averages will be equal to the mean of the population, and the standard air of the sample averages will be equal to the population. Standard deviation divided by the square root of the sample size. So this is our standard error of the sampling distribution, And so this is equal to 3.2. So that is your answer. That is the standard error of the sampling distribution. When the sample size is 100 is 32 I hope that helped
Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.
Velocity is <u>distance divided by time</u>, that is:
- She walked <u>3 miles</u> at a velocity of <u>6 miles per hour</u>, thus
. The time is:
- Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.
- Distance of <u>3 miles,</u> velocity of <u>2 miles per hour,</u> thus
. The time she took to return, in hours, is:
1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

B. They are similar triangles, and so the hypotenuses of the two triangles will be different sizes of the same line.
