Answer:
Option given in the top right.
Step-by-step explanation:
If an acute triangle is rotated about a point,
- Angles of the transformed triangle remain unchanged.
If a triangle is dilated by a scale factor of 
,
- Measure of sides of the image will be dilated by a scale factor of 0.5.
Therefore, statement that compares ΔABC to ΔA'B'C' will be,
The angle measures of the triangle A'B'C'are the same of those ΔABC, but the side length of the ΔA'B'C' half the size of those of ΔABC.
Option given in the top right is the answer.
Answer:
At this point just get ready for that whooping, aint no door expert gonna save you.
Step-by-step explanation:
Answer:
b)
{t | –3 < t ≤ 5}
Step-by-step explanation:
–4 < 3t + 5 ≤ 20
⇔
-4 - 5 < 3t ≤ 15
⇔
-9 < 3t ≤ 15
⇔
-3 < t ≤ 5
Answer:
See below
Step-by-step explanation:
Let's take it part by part:
(3-4)+(11+21)-3
-1+(32)-3
-4+32

Answer:
Yes, we can conclude that average sales has changed.
Step-by-step explanation:
The null hypothesis, H0 : μ = 0.3
The alternative ; H0 : μ ≠ 0.3
The result of the 95% confidence interval of (.3095, .3275); This shows that the confidence interval is now between 30.95% and 32.75% ; since μ does not lie within the confidence interval value and the lower boundary of the confidence interval is > 30; we Can conclude with an evidence of 5% significance that his average sales as changed (increased).
We can reject H0 and conclude that μ > 0.3
