Answer:
<em>R'(-3,-1), S'(-1,-3), T'(-4,'5).</em>
Step-by-step explanation:
<u>Rotations</u>
Rotating a point of coordinates M(h,k) through 180° about the origin maps it to coordinates to M'(-h, -k).
The triangle has the vertices at R(3,1), S(1,3), T(4,5). After a rotation of 180° about the origin it maps to a new triangle with coordinates:
R'(-3,-1), S'(-1,-3), T'(-4,'5).
An image of both triangles is shown below.
Answer:75,
Step-by-step explanation:
1/2 bh= A for one T 5*5=25 25*6= 150
150/2=75
OR
5*5/2=12.5
12.5*6=75
Think is A you can find a linear relationship by using the formula f(x)=mx+b hope it help
Good luck on the test btw
Answer:
The point estimate for the proportion is p = 0.4725
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
Point estimate
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
