Answer:
f(-3) = 4(-3) + 5 = -12 + 5 = -7. the answer is #2.
D.) 15/6
- 3 times 52 = 156, and since you can't exactly convert it to a fraction then i'm assuming that it is 'D'.

Answer:
A sample size of 35 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the width W as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that 
, then 
. So
Rounding up
A sample size of 35 is needed.
Answer:
A. She can rotate AABC 90° and then compare the angles and sides.
She will see that the triangles are congruent by the Angle Side Angle theorem.
Step-by-step explanation:
Congruent is a term that implies that a thing is identical to another (having the same shape and size). For congruent triangles, they have the same shape and size; they can be tilted or rotated to be at different angles but they have the same shape and size irrespective.
The following information were given:
D - 30°, 3 cm, 65°
B - 30°, 3 cm, 65°
From this information, we can conclude that <u>the triangles are congruent based on the Angle Side Angle theorem</u>. However, because the diagram was not included, we cannot conclusively say which is the more accurate answer between Options A & B.
