Write the sets of all possible factors and the sets of common factors of the pairs of numbers, then find their H.C.F. could you

abruzzese [7]

Answer:

a= 1,2,4 b= 1,2,3,6 c=1,2,4 d=1,2,5,10 e=1,2,3,4,6,12 H.C.F of all the pairs= 2

Step-by-step explanation:

Factors of:

a. 8=1,2,4,8

12=1,2,3,4,6,12.

common factor=1,2,4

b. 12=1,2,3,4,6,12

18=1,2,3,6,9,18

common factor=1,2,3,6

c. 16=1,2,4,16

24=1,2,3,4,6,8,12,24

common factor=1,2,4

d. 20=1,2,4,5,10,20

30=1,2,3,5,6,10,15,30

common factor=1,2,5,10

e. 24=1,2,3,4,6,8,12,24

36=1,2,3,4,6,9,12,18,36

common factor=1,2,3,4,6,12

HIGHEST COMMON FACTOR (H.C.F)=

The factor common to the whole pairs

which is 1 and 2

therefore 1 multiplied by 2 which is equal to 2

(and in Mathematics means multiplication)

Alex is a member of the school track and field team. His times for running various distances are shown. Create a scatter plot fo

frozen [14]

Answer:

(1) Please find attached the graph of the data

(2) 160.396 m

(3) The correlation that exist is a straight line correlation

Step-by-step explanation:

The given data are;

Distance, Time

(m), (s)

50, 6.1

100, 12

150, 18.3

200, 25.2

250, 31.7

(2)

Based on the linear regression formula, we have;

$b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}$

$b = \dfrac{5 \times 17215 - 93.3 \times 750}{5 \times 2156.03 -8704.89} = 7.758$

$a = \dfrac{\sum Y - b\sum X}{N}$

$a = \dfrac{750 - 7.7581 \times 93.3}{5}= 5.234$

The line is

y = 7.7581×x+5.234

When t = 20 s, we have

y = 7.7581*20+5.234 = 160.396 m

(3) The correlation that exist is a straight line correlation

What is the slope of the line? a. -5/2 b. -2/5 c. 2/5 d. 5/2

Sladkaya [172]

Change in y: -2, goes down 2
Change in x: 5, goes right 5
slope: change in y/ change is x
which is -2/5, and that's B
