In an extensive government study conducted this year a simple random sample of 500 households was obtained and 80 had experienced property damage due to a crime. Calculate and interpret a 95% confidence interval for the true proportion of households that have experienced property damage due to crime
Using the z-distribution, the 95% confidence interval is (0.1279, 0.1921), and it means that we are 95% sure that the proportion for the entire population is between these two values.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem:
A sample of 500 households was obtained and 80 had experienced property damage due to a crime, hence [tex]n = 500, \pi = \frac{80}{500} = 0.16[/tex].95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].Hence:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.16 - 1.96\sqrt{\frac{0.16(0.84)}{500}} = 0.1279[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.16 + 1.96\sqrt{\frac{0.16(0.84)}{500}} = 0.1921[/tex]
The 95% confidence interval for the true proportion of households that have experienced property damage due to crime is (0.1279, 0.1921), and it means that we are 95% sure that the proportion for the entire population is between these two values.

find the equation of the line that passes through the point (3,5) and is parallel to the equation of the line y=2×-5
Answer:
y=2x-1
Step-by-step explanation:
Since it is parallel to y=2x-5, they have the same slope of 2.
Now you're going to plug the point and slope into the following equation: y-(y value of point) = slope ×(x-(x value of point))
y-5= 2 (x-3)
Now you simplify:
y-5=2x -6
y=2x-1

Help plssss geometry!!
Answer:
x=4
Step-by-step explanation:
both angles add up to 90* because it is a right angle
10x + 12x + 2 = 90
22x + 2 = 90
subtract 2 from both sides of the equation
22x = 88
divide both sides by 22
x = 4

PARALLELOGRAM QUESTION, LOTS OF POINTS! (i will report if you dont answer correctly)
Answer:
65°
step-by-step explanation:
opposite angles of a parallelogram are of equal measure.solve for x:
116x - 1 = 114x + 1
116x - 114x = 1 + 1
2x = 2
x = 1
Find angle C:
The base angles in parallelogram sum up to 180°m∠C + 116(1) - 1 = 180°
m∠C = 180° - 115
m∠C = 65°
Solution:
We know that:
Opposite angles in a parallelogram are equal.Sum of the angles in a quadrilateral always sum up to 360°This means that:
[tex]116x - 1 = 114x + 1[/tex][tex]\angle C = \angle E[/tex][tex](116x - 1) + (114x + 1) + \angle C + \angle E = 360\°[/tex]Step-1: Find the value of x.
[tex]116x - 1 = 114x + 1[/tex]
[tex]\rightarrow 116x - 114x = 1 + 1[/tex]
[tex]\rightarrow 2x = 2[/tex]
[tex]\rightarrow \bold{x = 1}[/tex]
Step-2: Solve for ∠C.
[tex](116x - 1) + (114x + 1) + \angle C + \angle C = 360\°[/tex]
[tex]\rightarrow (116x - 1) + (114x + 1) + \angle C + \angle E = 360\°[/tex] [∠C = ∠E]
[tex]\rightarrow 116x - 1 + 114x + 1 + 2\angle C = 360\°[/tex]
[tex]\rightarrow 230x + 2\angle C = 360\°[/tex]
[tex]\rightarrow 230(1) + 2\angle C = 360\°[/tex] [x = 1]
[tex]\rightarrow 230 + 2\angle C = 360\°[/tex]
[tex]\rightarrow 2\angle C = 360 - 230[/tex]
[tex]\rightarrow 2\angle C = 130[/tex]
[tex]\rightarrow \boxed{\bold{\angle C = \frac{130}{2} = 65\°}}[/tex]
3 A scientist takes four random samples of a population of 700 trees. Each sample is
the same size. The first sample indicates that 30% of the trees are oak, while the
second sample indicates that only 15% of the trees are oak. The third sample
indicates that 26% of the trees are oak. The fourth sample indicates that 29% of
the trees are oak. Based on the data, about how many of the 700 trees are oak?
Using proportions, it is found that about 175 trees are oak.
What is a proportion?A proportion is a fraction of a total amount.
For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.
Hence, the mean proportion is given by:
M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Let 'x' represent the number of yards of silk and 'y' represent the number of yards of cotton.
Here is a system of equations that represent the constraints in the situation.
x+y=4.25
16.90x+4y=36.35
Find the solution to the system of equations. You may use any method you want, but you must explain your reasoning and methods fully.
Answer:
Step-by-step explanation:
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.
x + y = 4.25 equation 1
16.90x + 4y = 36.25 equation 2
where:
x = yards of silk bought
y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards
In order to determine the value of y, substitute for x in equation 1
1.49 + y = 4.25
y = 4.25 - 1.49
y = 2.76 yards
Answer:
Step-by-step explanation:
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.
x + y = 4.25 equation 1
16.90x + 4y = 36.25 equation 2
where:
x = yards of silk bought
y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards

Answer:
B = 48°
b = 29.7
c = 39.1
Step-by-step explanation:
You have made a Mistake which is C = 102° Not 120°
So, Lets begin with the Problem
Since the Sum of Interior Angles of the Triangle = 180 °
Then A+B+C=180
Then 30+B+102=180
Then B+132=180
Subtract 132 from Both sides
B = 180 - 132 = 48°
Applying Law of Sines
[tex]\frac{a}{sinA} =\frac{b}{sinB}=\frac{c}{sinC}[/tex]

Then [tex]b=\frac{20sin48}{sin30} =29.7[/tex]
