7 0

Answer:

7/15

Step-by-step explanation:

So basically, you need to count the numbers (3,5,7,9,11,13,15) those are 7 numbers in total, so that's 7/15, if you want a percentage its 47% (rounded)

A dilation has center at the origin. Which of the following is the image of the point PC - 3) for a scale

Crank

Answer:

The image of the point p is p'(\frac{1}{4},\frac{-5}{14}).

Step-by-step explanation:

The center of dilation is origin and the scale factor is \frac{1}{7}.

The coordinates of point p are

(\frac{7}{4},\frac{-5}{2})

If k is the scale factor and origin is the center of dilation, then

(x,y)\rightarrow (kx,ky)

Since the scale factor is \frac{1}{7} and the origin is the center of dilation, therefore

(x,y)\rightarrow (\frac{1}{7}x,\frac{1}{7}y)

The coordinates of image of p are

p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{7}\times \frac{7}{4},\frac{1}{7}\times \frac{-5}{2})

p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{4},\frac{-5}{14})

Therefore the image of the point p is p'(\frac{1}{4},\frac{-5}{14}).

In a random sample of 257 adult Orcas in the wild, there were 159 whose total body length was 28 feet or longer. Create a 98% co

REY [17]

Answer:

98% Confidence interval: (0.5483,0.6891)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 257

Number of adults total body length was 28 feet or longer, x = 159

$\hat{p} = \dfrac{x}{n} = \dfrac{159}{257} = 0.6187$
