Answer:
Pentagon, convex
Step-by-step explanation:
All of the interior angles are less than 180. Hope this helps.
7-5.5=1.5
so each drop leaf is 1.5
2×1.5=3
so 7 when both drop leafs are up
7-3=4
There's your answer
Answer:
95% confidence interval for the percentage of all U.S. public high school students who are obese is [0.110 , 0.190].
Step-by-step explanation:
We are given that 15% of a random sample of 300 U.S. public high school students were obese.
Firstly, the pivotal quantity for 95% confidence interval for the population proportion is given by;
P.Q. =
~ N(0,1)
where,
= sample % of U.S. public high school students who were obese = 15%
n = sample of U.S. public high school students = 300
p = population percentage of all U.S. public high school students
<em>Here for constructing 95% confidence interval we have used One-sample z proportion statistics.</em>
<u></u>
<u>So, 95% confidence interval for the population proportion, p is ;</u>
P(-1.96 < N(0,1) < 1.96) = 0.95 {As the critical value of z at 2.5% level
of significance are -1.96 & 1.96}
P(-1.96 <
< 1.96) = 0.95
P(
<
<
) = 0.95
P(
< p <
) = 0.95
<u>95% confidence interval for p</u> = [
,
]
= [
,
]
= [0.110 , 0.190]
Therefore, 95% confidence interval for the percentage of all U.S. public high school students who are obese is [0.110 , 0.190].
50% is exactly half, so to find half of something you just divide it by 2= 7.5
Or you could multiply it
15 x 0.50=7.5
For an eqtuaion wih slope m and goes through point (x1,y1)
equation is
y-y1=m(x-x1)
so
point (-1,6)
slope=-3
y-6=-3(x-(-1))
y-6=-3(x+1)
