The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
Answer:
2 of these numbers are divisible by 4 and 5.
20 and 60 are divisible by 4 and 5.
Step-by-step explanation:
20 is divisible by 4 and 5.
Divisible just means that the 4 (also the 5) goes into 20 evenly, with no remainder.
4 goes into 20 evenly with no remainder.
5 goes into 20 evenly with no remainder.
4 does not go into 35 evenly with no remainder.
35 ÷ 4 is 8 with a remainder of 3.
35 ÷ 4 = 8.75
5 does go into 35. 35 is divisible by 5.
35 is not divisible by 4.
60 is divisible by 4
60 ÷ 4 = 15 (no remainder, no extra decimals if you do it on a calculator)
60 ÷ 5 = 12 (no remainder, no extra decimals if you do it on a calculator)
60 is divisible by 4 and also by 5.
Answer:
it is a^2 +b^2 =c^2
Step-by-step explanation:
you square the width and the length and add them and you get the hypotenuse
then you find the root of the hypotenuse and that is our answer
Answer:
12
Step-by-step explanation:
84/7 is 12, so she was going 12 mph
Answer:
Both means are apprxoimately equal at 1% level of significance.
Step-by-step explanation:
Given is the information summarised below
Group Men Women
Mean 23.00 28.00
SD 5.00 10.00
SEM 1.00 1.83
N 25 30
H0: Mean of mean = mean of women
Ha: means of men < mean of women
(Left tailed test)
Since population std deviation is known but sample sizes are small t test is used.
The mean of Men minus Women equals -5.00
standard error of difference = 2.201
t = 2.2721
df = 53
p value= 0.0136
since p >0.01 at 1% significance level we fail to reject H0.
Both means are apprxoimately equal at 1% level of significance.
