angle 1 (s):

angle 2 (t): t < 2s

s + t = 90

t < 2s

You didn't provide the choices so hopefully you can figure it out with the information I provided.

Note: "t" must be less than 30

An economics professor randomly selected 100 millionaires in the U.S. The average age of these millionaires was 52.1 years with

Veronika [31]

Answer:

$52.1-1.984\frac{12.3}{\sqrt{100}}=49.66$

$52.1 +1.984\frac{12.3}{\sqrt{100}}=54.54$

The 95% confidence interval would be given by (49.66;54.54)

Step-by-step explanation:

Information given

$\bar X= 52.1$ represent the sample mean

$\mu$ population mean (variable of interest)

s=12.3 represent the sample standard deviation

n=100 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

The degrees of freedom are given by:

$df=n-1=100-1=99$

The Confidence is 0.95 or 95%, and the significance would be $\alpha=0.05$ and $\alpha/2 =0.025$ , the critical value for this case is: $t_{\alpha/2}=1.984$

Replacing the info given we got:

$52.1- 1.984\frac{12.3}{\sqrt{100}}=49.66$

$52.1 +1.984\frac{12.3}{\sqrt{100}}=54.54$

The 95% confidence interval would be given by (49.66;54.54)

On a computer screen, Jennifer just created a triangular design of banner with vertices at A (-4,3) B(-1,5) and C (-1,2) she can

WITCHER [35]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, reflection, translation and rotation.

Given the vertices A (-4,3) B(-1,5) and C (-1,2).

If the vertices is reflected across the y = -1 line, the new location would be at:

A' (-4, -5). B'(-1, -7) and C'(-1, -4)

If it is then translated 8 units to the right i.e. (x, y) ⇒ (x + 8, y), the new location would be at:

A"(4, 5), B"(7, -7) and C"(7, -4)
