Answer:
B. 18 feet
Step-by-step explanation:
a circle has 360 degrees
so circumference = (360 / 60) * 3 = 6*3 = 18 feet
Answer:
Null hypothesis: ∪ₐ = ∪ₓ
Alternative hypothesis: ∪ₐ ≠ ∪ₓ
Step-by-step explanation:
Null hypothesis: ∪ₐ = ∪ₓ
Alternative hypothesis: ∪ₐ ≠ ∪ₓ
where ∪ₐ represents mean of sample of new cars and ∪ₓ represents mean of sample of older cars.
Using a difference in means t test will help determine if new owners tune up their cars more frequently than older car owners.
Answer:
Step-by-step explanation:
If the degree of the polynomial is even (positive) ends of the function will either upwards or downwards on axis.
If the coefficient of the leading term of a polynomial is negative, both the ends of the graph will move downwards.
The given function is,
f(x) = -x⁴ + 9
Degree of the polynomial = 4
Coefficient of the leading term = -1
Therefore, ends of the polynomial will open downwards.
Answer:
-3, -9, -7
Step-by-step explanation:
Answer:
Δ MNO ≅ ΔXYZ by AAS postulate.
Step-by-step explanation:
Given:
,
, and YO = NZ.
Consider YO = NZ
Add OZ on both sides
YO + OZ = NZ + OZ
YZ = NO
Consider triangles Δ MNO and ΔXYZ.
Statement Reason
1.
Given
2.
Given
3. YZ = NO ∵ YO = NZ
Therefore, the two triangles Δ MNO and ΔXYZ are congruent to each other from AAS postulate as two corresponding angles and a corresponding side are equal to each other.
