Answer:

5 - number summary:

Minimum : 664

First quartile : 706

Median : 766

Upper quartile : 810

Maximum : 836

Step-by-step explanation:

Given the data:

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Sorted data :

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Minimum =664

Lower quartile (Q1) = 1/4(n+1)th term

Q1 = 1/4(13) = 3.25 = (3rd + 4th) = (698 + 714) / 2 = 706

Median (Q2) = 1/2(n+1)th term

Q2 = 1/2(13) = 6.5 = (6th + 7th) = (753 + 779) / 2 = 766

Upper quartile (Q3) = 3/4(n+1)th term

Q3 = 3/4(13) = 9.75 = (9th + 10th) = (802 + 818) / 2 = 810

Maximum = 836

Answer:

ΔABC ~ ΔDEC

Step-by-step explanation:

Given : DE║AB

              Statements                              Reasons

1). DE║AB                                              1). Given

2). ∠CDE ≅ ∠CAB                                2). Corresponding angles

                                                [Since DE║AB and AC is the transverse]

3). ∠CED ≅ ∠CBA                                3). Corresponding angles

                                                [Since DE║AB and BC is the transverse]

4). ΔABC ~ ΔDEC                                 4). By AA property of similarity    

Hence ΔABC is similar to ΔDEC.

The equation of the line passing through the points (3, 16) and (5, 10) can be expressed as y = mx + b. Give the value of b
Alenkinab [10]

we are given two points as

(3, 16) and (5, 10)

firstly , we will find slope

slope is m

so, we can use formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug points

m=\frac{10-16}{5-3}

m=\frac{-6}{2}

m=-3

we can plug it in y=mx+b

we get

y=-3x+b

now, we can select any one points

and find b

(3,16)

x=3 and y=16

16=-3*3+b

we can find b

b=25

now, we can plug back b

and we get

y=-3x+25

so, equation is

y=-3x+25

and

b=25...............Answer
