Kendra reads in Modern Dog Magazine that the average age of dogs currently alive is 4.8 years. To determine if this finding appl

Answer:

The true statement about Kendra's sample is:

b) Kendra's samples are precise but not accurate.

Step-by-step explanation:

a) Data and Calculations:

Average age of dogs currently alive = 4.8 years

Average ages of dogs in Kendra's sample

Week Average Age (in years)

1 3.7

2 3.8

3 4.2

4 4.1

5 3.9

6 3.9

7 4.0

Total 27.6

Mean = 3.9 (27.6/7)

b) Accuracy refers to how close Kendra's sample mean age of dogs is to the average age value as stated in the Modern Dog Magazine. While the Magazine stated an average age of 4.8 years, Kendra's sample produced a mean of 3.9 years. On the other hand, precision refers to how close Kendra's sample measurements are to each other. With a mean of 3.9 years, the sample measurements are very close to each other. Therefore, we can conclude that "Kendra's samples are precise but not accurate."

PLSS HELPP WILL GIVE BRAINLIEST PLS ANSWER ALL 3

podryga [215]

Answer:

$\large \boxed{\sf non \ linear, \ non \ linear, \ linear, \ linear}$

Step-by-step explanation:

Write the equations in the form y = mx + b

If the equation contains exponents then it is non-linear, if not then it is linear.

2xy = 3

This graph forms a curve so it is non-linear

y = 1x³ + 5

This equation is non-linear because it contains an exponent

y = x/3

y = 1/3x + 0

This equation is linear ( no exponent(s) )

2y = 1/2x

y = 1/4x + 0

This equation is linear ( no exponent(s) )

Solve for x: 1/8 = x/12 I don't need work shown just need answer<br>

Dimas [21]

Answer:

3/2 =x

Step-by-step explanation:

1/8 = x/12

Solve using cross products

1 * 12 = 8x

12 = 8x

Divide each side by 8

12/8 =8x/8

3/2 =x

Triangle HAM is reflected over the y-axis using the rule (x, y) → (−x, y) to create triangle H′A′M′. If a line segment is drawn

GuDViN [60]

The statement that best describes the line segment drawn in relation to the y-axis is (c) the y-axis is a bisector of the segment drawn.

The transformation rule is given as:

$(x,y) \to (-x,y)$

When the triangle is reflected to form triangle H'A'M', the vertices of triangle H'A'M' would be:

$H'A'M' = (-x,y)$

So, the distance from point A to the y-axis is equidistant to the distance from point A' to the y-axis.

This, in other words means that the y-axis bisects the line segment AA'.

Hence, the relation between the segment and the y-axis is (c)
