Answer:
Step-by-step explanation:
a) Frequency table:
Category Frequency
Dog 4
Cat 3
Fish 2
Hamster 1
b) Relative frequencies of each animal type
Dog: 4/10 = 0.4
Cat: 3/10 = 0.3
Fish: 2/10 = 0.2
Hamster: 1/10 = 0.1

Answer:
x=15
Step-by-step explanation:
since 6 is 3/4 of 8 and the figures are similar x must be 3/4 of 20
3/4 of 20 is 15
good day to you
Your answer is 38-8i because what you do is 1 times 3 and get 3 then 1 times 7i and get 7i then you do -5i times 3 and you get -15i then -5i times 7i and you get -35i2 and the square will cancel out the negative and make it 35 then add that to the 3 and you get 38 then take the -15i +7i and get -8 do your answer is 38-8i
Answer:
Step-by-step explanation:
<u><em>the mean in period</em></u> 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
<u><em>the mean in period</em></u> 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
