Answer:
The Domain is that X is between -6 and 6
The range is that y is between -8 and 4
Step-by-step explanation:
Look at the two endpoints of the function. You can see that the left-most point is at (-6, 4) and the right-most point is at (6, -8)
ABC has
A as the first letter
B as the second letter
C as the third letter
The order is important
Similarly with EFG we hae
E as the first letter
F as the second letter
G as the third letter
The order is also important
Based on the orderings, we can say
A corresponds to E
B corresponds to F
C corresponds to G
Which means
A rotates to E
B rotates to F
C rotates to G
The final answer is choice C) Angle C
since we're looking for the angle that rotates or maps to angle G
Answer:
The 99% confidence interval of the population standard deviation is 1.7047 < σ < 7.485
Step-by-step explanation:
Confidence interval of standard deviation is given as follows;
s = 
Where:
= Sample mean
s = Sample standard deviation
n = Sample size = 7
χ = Chi squared value at the given confidence level
= ∑x/n = (62 + 58 + 58 + 56 + 60 +53 + 58)/7 = 57.857
The sample standard deviation s = = 2.854
The test statistic, derived through computation, = ±3.707
Which gives;
1.7047 < σ < 7.485
The 99% confidence interval of the population standard deviation = 1.7047 < σ < 7.485.
57/7=8.14 so Carols ran 1 mile in 8.14 minutes
3*4=12 so June can run 1 mile in 12 minutes
Answer:
x = 17
Step-by-step explanation:
x + x + 8 = 42 because x = boys and x + 8 = girls
2x = 34 because 2x = 42 - 8
x = 17
i hope this helps! you don't need the 2x = 42 - 8 to be an equation ;)
