Answers

Answer:

2. Linear

Step-by-step explanation:

1. Exponential

Principal = 15000

Rate, r = 6.5% compounded annually

A = P(1 + r)^t

A = 15000(1 + 0.065)^t

A = 15000(1.065)^t

To decide whether the point lies on the circle, what you need to do it simply substituting the x and y values into the equation and check if it add up to be 25

(-5)² + 0² = 25, = RHS  [Yes]

1² + (√7)² = 8, ≠ RHS [No]

(√21)² + (-3)² = 30, ≠RHS [No]

0² + 7² = 49, ≠RHS [No]

Write the equation of the line that is perpendicular to y = -2/3 x +2 and goes through the point (-1, 4). Make sure your final answer is in slope-intercept form

Answers

Given:

The equation of a line is

[tex]y=-\dfrac{2}{3}x+2[/tex]          ...(i)

The perpendicular line passes through the point (-1,4).

To find:

The equation of the perpendicular line.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]            ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

[tex]m=-\dfrac{2}{3}[/tex]

Product of slopes of two perpendicular lines is -1.

Let the slope of perpendicular line is [tex]m_1[/tex].

[tex]m\times m_1=-1[/tex]

[tex]-\dfrac{2}{3}\times m_1=-1[/tex]

[tex]m_1=\dfrac{3}{2}[/tex]

The slope of the perpendicular line is [tex]m_1=\dfrac{3}{2}[/tex] and it passes through the point (-1,4). So, the equation of the line is:

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-4=\dfrac{3}{2}(x-(-1))[/tex]

[tex]y-4=\dfrac{3}{2}(x+1)[/tex]

[tex]y-4=\dfrac{3}{2}x+\dfrac{3}{2}[/tex]

Add 4 on both sides.

[tex]y-4+4=\dfrac{3}{2}x+\dfrac{3}{2}+4[/tex]

[tex]y=\dfrac{3}{2}x+\dfrac{3+8}{2}[/tex]

[tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex]

Therefore, the equation of required line is [tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex].

Penn State extension is interested in comparing the body length southern grass cicadas and citrus cicadas. The extension collected a random sample of 20 southern grass cicadas and found that they have a mean body length of 16.22 millimeters and a standard deviation of 1.34 millimeters. A separate random sample of 20 citrus cicadas resulted in a mean body length of 13.41 millimeters and a standard deviation of .73 millimeters. What is the standard error of the difference parentheses southern grass minus citrus) between the sample means

Answers

Answer:

The standard error between the sample mean is approximately 0.3412

Step-by-step explanation:

The equation for the standard error of a difference in sample mean of equal sample sizes is given as follows;

[tex]SE(\overline x_1 - \overline x_2)={\sqrt{\dfrac{s_{1}^{2} }{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]

The given parameters are;

The number of sample of southern grass cicadas, n₁ = 20

The mean body length of the southern grass cicadas, [tex]\overline x _1[/tex] = 16.22 mm

The standard deviation, s₁ = 1.34 mm

The number of sample of citrus cicadas, n₂ = 20

The mean body length of the citrus cicadas, [tex]\overline x _2[/tex] = 13.41 mm

The standard deviation, s₂ = 0.73 mm

[tex]SE(16.22 - 13.41)={\sqrt{\dfrac{1.34^{2} }{20}+\dfrac{0.73^{2}}{20}}} \approx 0.3412[/tex]

The standard error between the sample mean, SE ≈ 0.3412
