Answer:
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%
Step-by-step explanation:
The null hypothesis is the problem statement and the alternate hypothesis is a contradiction of null hypothesis
Hence,
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%
Answer:
9.7%
Step-by-step explanation:
Given:
Observed score value = 8.5
Actual score value = 7.75
Required:
Percent error to the nearest tenth
SOLUTION:
Percent error = \frac{Value_{observed} - Value_{actual}}{Value_{actual} * 100 [/tex]
Percent error = \frac{8.5 - 7.75}{7.75} * 100 [/tex]
Percent error = \frac{0.75}{7.75} * 100 [/tex]
Percent error = \frac{75}{7.75} [/tex]
Percent error = 9.7 [/tex] (nearest tenth)
-2 and 2
-2 0 and 2
i hope this helps
you can try to pair ech of them and calculate like -2 with -1 no then -2 0 no -2 2 yes then with pair of three -2 -1 0 no etc-2 0 -2 yes
Answer:
Q.5 ab=cd
Q.6 ad=bc
Q.7 ce=ae
Q.8 eb=ed
Q.9 angle D=angle B (opposite angle of parallelogram are equal)
let other angle of parallelogram be x.
angle A+angle B +angle C + angle D= 360° (sum of quadrilateral is 360°)
x+130°+x+130°=360°
2x+260°=360°
2x=360°-260°
2x=100°
x=100/2
x=50°
Q.10 similarly, angle b= angle d
let other angle be x.
x+61°+ x+61°=360°
2x+122°=360°
2x=360°+122°
2x=238°
x=238°/2
x=119°
Q.11 in quadrilateral opposite angles are equal and opposite angle of parallelogram are equal.
Q.12 in quadrilateral opposite angle are equal and opposite angle of parallelogram are equal.
Q.13 in quadrilateral opposite sides are equal and opposite sides are parellel and this property is also present in parallelogram.
