Answer:
<em>The slope would be</em><u><em> -1/2.
</em></u>
Step-by-step explanation:
Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),
<em>
= </em><u><em>( 4, -2 ),
</em></u>
Now, the slope of the line passes through the origin and the point ( 4, -2) is,
= <u>-1/2</u>

A. This expression has 4 terms
B. The constants are -5, 3, 72 and 10
C. The third term is 72
D. The coefficient is y
Answer:
10
Step-by-step explanation:
40=2 x 2 x 2 x 5
50=2 x 5 x 5
therefore, GFC = 2x5
GFC= 10
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Group 1:
μ1 = 59.7
s1 = 2.8
n1 = sample size = 12
Group 2:
μ2 = 64.7
s2 = 8.3
n2 = sample size = 15
α = 0.1
Assume normal distribution and equ sample variance
A.)
Null and alternative hypothesis
Null : μ1 = μ2
Alternative : μ1 < μ2
B.)
USing the t test
Test statistic :
t = (m1 - m2) / S(√1/n1 + 1/n2)
S = √(((n1 - 1)s²1 + (n2 - 1)s²2) / (n1 + n2 - 2))
S = √(((12 - 1)2.8^2 + (15 - 1)8.3^2) / (12 + 15 - 2))
S = 6.4829005
t = (59.7 - 64.7) / 6.4829005(√1/12 + 1/15)
t = - 5 / 2.5108165
tstat = −1.991384
Decision rule :
If tstat < - tα, (n1+n2-2) ; reject the Null
tstat < t0.1,25
From t table :
-t0.1, 25 = - 1.3163
tstat = - 1.9913
-1.9913 < - 1.3163 ; Hence reject the Null
<span>the answer is 59.25 – 8.67 = </span>50.58
