Answer:
x= -2
Step-by-step explanation:
The first thing I did was isolate the x's on one side. I subtracted 38x from both sides. This gives me:
-9x=18.
Now i divide both sides by -9. Giving me x=-2
2x+3y=6
3y=-2x+6
3y/3=-2x+6/3
Y=-2/3x+2
Answer is SSA (first choice)
cause LE perpendicular to BU so LEB = LEU = 90
hope it helps
Answer:
- Two sided t-test ( d )
- 0.245782 ( c )
- Since P-value is too large we cannot conclude that the students’ weight are different for these two schools. ( c )
- The test is inconclusive; thus we cannot claim that the average weights are different. ( b )
Step-by-step explanation:
1) Test performed is a Two sided test and this because we are trying to determine the mean difference between two groups irrespective of their direction
<u>2) Determine the P-value ( we will use a data-data analysis approach on excel data sheet while assuming Unequal variances )</u>
yes No
Mean 94.47059 89.76471
Variance 173.2647 95.19118
Observations 17 17
df 30
t Stat 1.184211
P(T<=t) one-tail 0.122814
t Critical one-tail 1.697261
P(T<=t) two-tail 0.245782
Hence The p-value = 0.245782
3) Since P-value is too large we cannot conclude that the students’ weight are different for these two schools.
4) The test is inconclusive; thus we cannot claim that the average weights are different.
