The best point estimate for the proportion of all the residents opposed to the photo cop use is 60% which is the fourth option.
Given that in a survey of 456 residents , 279 were opposed to the use of the photo cop for issuing traffic tickets.
We have to find the best point estimate for the proportion of all residents opposed to the photo cop use.
Total residents=456
Residents who opposed to the use of the photo cop for issuing traffic tickets=279
Proportion=number of residents who opposed/ total residents
=279/456
=0.611
=61.1%
The nearest option is fourth which is 60%.
Hence the best point estimate for the proportion for the proportion of all the residents opposed to the photo cop use is 60% which is option 4.

Answer:
60mph
Step-by-step explanation:
Let d be the distance. Let v be the speed of car a. That means the speed of car b is v + 15. Now we can set up 2 equations using the v = d/t:
Car a: v = d / 2 --> d = 2v
Car b: v + 15 = d / 1.5
We can solve for v by substituting the first equation (rearranged to isolate d) into the second:
v + 15 = 2v / 1.5
1.5v + 22.5 = 2v
0.5v = 22.5
v = 45
We're looking for the speed of car b, which was v + 15 = 45 + 15 = 60.
Well it has to be 3*2 = 6 square feet. Note: first convert 36 inches to 3 feet and 24 inches to 2 feet.
Answer:
x = 10°
Step-by-step explanation:
a). Since, opposite angles of a cyclic quadrilateral are supplementary angles"
Therefore, in cyclic quadrilateral ABDE,
m∠ABD + m∠AED = 180°
110° + m∠AED = 180°
m∠AED = 180° - 110°
= 70°
b). AD = ED [Given]
m∠EAD = m∠AED [Since, opposite angles of equal sides are equal in measure]
m∠EAD = m∠AED = 70°
By triangle sum theorem in ΔABD,
m∠BAD + m∠ABD + m∠ADB = 180°
m∠BAD + 110° + 40° = 180°
m∠BAD = 180 - 150
= 30°
m∠AEB = m∠AED + m∠DAB [By angles addition postulate]
m∠AEB = 70° + 30°
= 100°
By triangle sum theorem in the large triangle,
x° + m∠AEB + m∠EAB = 180°
x° + 100° + 70° = 180°
x = 180 - 170
x = 10°
