Answer:
40/3 option B
Step-by-step explanation:
20-10+5-5/2+ ...
We need to find the sum of infinite geometric series
a is the first term (20)
r is the common ratio
To find common ratio we divide second term by first term
r=
now we plug in the values
sum = 40/3
Answer:
X=6
Step-by-step explanation:
5x6=30+15
Eazy 44,756
then you do 167 not take 447 the first part of the first number now can 167 go into 447 yes it can then from there wants you have leftover numbers then add 5 to the leftover and see if 167 can go into it from there take the last digit from 44,756 and there you go
Answer:
C is the equation that is perpendicular and goes through the given point.
Step-by-step explanation:
In order to find this, we first need to find an equation with the appropriate slope. Perpendicular lines have opposite and reciprocal slopes. Since the slope of the original line is 1, we need a line with -1 slope. C and D are the only such answers that have this slope.
Next we look for it to fit into the following point slope equation.
y - y1 =m(x - x1)
We use the point (2, 5) as (x1, y1). So we can plug those in the spots that we see above as well as the slope at m.
y - y1 =m(x - x1)
y - 5 = -(x - 2)
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.
