Answer:
(1, - 8 )
Step-by-step explanation:
Given that P'( - 6, - 4 ) is the image of P(- 2, 3 )
Then the rule is (x, y ) → (x - 4, y - 7 )
Thus
A(5, - 1 ) → A'(5 - 4, - 1 - 7 ) → A'(1, - 8 )
Answer:
Approximately, the 90% confidence interval for the students' mean IQ score is between 129.045 - 130.956
Step-by-step explanation:
The formula to use to solve this question is called the Confidence Interval formula.
Confidence interval =
x ± z × ( σ/ (√n) )
Where:
x = the sample mean = 130
z = the z-value for 90% confidence = 1.645
σ = standard deviation = 7
n = sample size = 145
130 ± 1.645 × (7/√145)
130 ± 0.9562687005
130 - 0.9562687005 = 129.0437313
130 + 0.9562687005 = 130.9562687005
Therefore, approximately, the 90% confidence interval for the students' mean IQ score is between 129.045 - 130.956
350*0.2=70
350-70=280
so the answer is 280
Answer:
4665 approx
Step-by-step explanation:
Given data
Total number of crashes= 16,370 automobile crashes
Percentage caused by distraction =28.5%
Let us find the number of crashes caused by distraction
=28.5/100* 16,370
=0.285* 16,370
=4665.45
Hence the number of crashes caused by distraction is 4665 approx
Answer:
2/35
Step-by-step explanation:
original equation:q+1/7=1/5
subtract both sides by 1/7
q=1/5-1/7
q=2/35
