For this case we have an exponential function of the form:

f (x) = A (b) ^ x

Where,

  • <em>A: the initial number of deer </em>
  • <em>b: rate of change </em>
  • <em>x: number of years </em>

We then have the following function:

f (x) = 248 (1.15) ^ x

After three years we have:

f (x) = 248 (1.15) ^ 3\\f (x) = 377

Answer:

the population 3 years after beginning the study is 377.

The farthest distance on the planet that the eye can see is given by the formula d=\sqrt{8,000h_1} + \sqrt{8,000h_2}

h_1= your first height and h_2=your second height

Since h_1=5 or the height of the periscope over the water and h_2=50 for the height of the ship the answer is 832.45553203368 feet, but because the question asks to the nearest mile the answer would be 11^a^0

aev [14]

Answer:

1. M=108

2. μ=110

3. In the explanation.

4. Test statistic t = -1.05

5. P-value = 0.1597

Step-by-step explanation:

The question is incomplete: to solve this problem, we need the sample information: size, mean and standard deviation.

We will assume a sample size of 10 matches, a sample mean of 108 points and a sample standard deviation of 6 points.

1. The mean points is the sample points and has a value of 108 points.

2. The null hypothesis is H0: μ=110, meaning that the mean score is not significantly less from 110 points.

3. This is a hypothesis test for the population mean.

The claim is that the mean score is significantly less than 110.

Then, the null and alternative hypothesis are:

H_0: \mu=110\\\\H_a:\mu< 110

The significance level is 0.05.

The sample has a size n=10.

The sample mean is M=108.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=6.

The estimated standard error of the mean is computed using the formula:

s_M=\dfrac{s}{\sqrt{n}}=\dfrac{6}{\sqrt{10}}=1.9

4. Then, we can calculate the t-statistic as:

t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{108-110}{1.9}=\dfrac{-2}{1.9}=-1.05

The degrees of freedom for this sample size are:

df=n-1=10-1=9

5. This test is a left-tailed test, with 9 degrees of freedom and t=-1.05, so the P-value for this test is calculated as (using a t-table):

\text{P-value}=P(t

As the P-value (0.1597) is bigger than the significance level (0.05), the effect is  not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that the mean score is significantly less than 110.

the slope is -a/b

slope=-20/25=-4/5
negative slope

yint is where x=0
20(0)+25y≥200

positive yint

x+y<10
slope=-1/1=-1
yint is where x=0
y<10
yint is at y=10

since it is equal, it is solid line
to tell if it is above then sub (0,0) and see if true

false
shade on side that doesn't have (0,0), shade above line


x+y<10 doesn't have equal under so it is dashed

0<10
true, it is shaded below

test point (4,5)

20(4)+25(5)≥200

true

4+5<10

true


so the ones that are true are

The line x + y < 10 has a negative slope and a positive y-intercept.
The line representing 20x + 25y ≥ 200 is solid and the graph is shaded above the line.
The overlapping region contains the point (4, 5).
