For the data shown in the scatter plot, which is the best estimate of r? -0.95, -0.55, 0.55, 0.95

1 answer:

6 0

From the data shown in the scater plots, the points are scattered apart which means that r is not close to 1.

Also the data points increase to the right which means that r is positive.

Therefore, the estimate for r in the data shown in the scatter plot is 0.55

Work out the lengths of side a and side b 8cm and 5 cm 1 triangle 17cm and 12 cm on the other triangle pythagoras

Viktor [21]

Answer:

a = 9.4 cm

b = 12.0 cm

Step-by-step explanation:

Check the image uploaded for diagram;

For the first diagram, side length a is calculated as follows;

a² = 8² + 5²

a² = 64 + 25

a² = 89

a = √89

a = 9.4 cm ( approximated to 1 decimal place)

For the second diagram, side length b is calculated as follows;

b² = 17² - 12²

b² = 145

b = √145

b = 12.0 cm (approximated to 1 decimal place)

Each side of the first figure is one unit copy and complete the table then find the function rule for the relationship between t

Perimeter of a shape is the total length of its border

Figure 1, perimeter = 5 units
Figure 2, perimeter = 7 units
Figure 3, perimeter = 9 units
Figure 4, perimeter = 11 units

Notice that the perimeter is forming an Arithmetic sequence; 5, 7, 9, 11 with a common difference of 2

The general form of an Arithmetic sequence is

$n_{th}term=dn+0^{th}term$

Where 'd' is a common difference and 'n' is the number of terms.

We have d = 2, and
zero term = the term before the first term = 3

$n_{th}term=2n+3$ ⇒ This is the rule to find the perimeter of the next figures

Find the distance between the two points.<br> (-1, -3), (1, 3)

allsm [11]

Answer:

d = 6.324555

Step-by-step explanation:

d=√1−(−1))^2+(3−(−3))^2

d=√(2)^2+(6)^2

d=√4+36

d=√40

d=6.324555
