Answer:
x = 50°Step-by-step explanation:
According to Angle sum property of triangle,
x + 45° + 85° = 180°
=> x = 180 - 85 - 45
=> x = 180 - 130
=> x = 50
Hence,
The missing angle x is 50° (Ans)
Answer:
45+85+x=180(sum of angle of triangle)
or, 130+x=180
or, x=180-130
x=50
Step-by-step explanation:
here, the sum of angle of triangle is 180

In 2002, there were 450 households in the city of Klean that recycled. Each year since 2002, the number of
households that recycle has grown by 8%. Write a function to represent the number of households
in Klean that recycle x years since 2002.
Answers
Answer:
450 x 1.08 ^ X = N
Step-by-step explanation:
Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:
450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle
450 x 1.08 ^ X = N
Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:
450 x 1.08 ^ 5 = N
450 x 1.4693 = N
661.20 = N

Step-by-step explanation:
We can use the midpoint formula . Here the points are , (2,2) and (3,5) .
• Using Midpoint Formula :-
⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }
⇒ M = ( 2+3/2 , 5+2/2 )
⇒ M = ( 5/2 , 7/2 )
⇒ M = ( 2.5 , 3.5 )
Hence the midpoint is (2.5 , 3.5)please help I'll give brainliest

With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes. a) With a significance level of 5 percent, conduct an appropriate test on the claim. (State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance
Answers
Answer:
H0 : σ²= 7.2²
H1 : σ² < 7.2
We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
Step-by-step explanation:
H0 : σ²= 7.2²
H1 : σ² < 7.2²
The test statistic :
X² = [(n - 1)*s² ÷ σ²]
s² = 3.5
n = sample size = 25. ; s²
X² = [(25 -1)*3.5² ÷ 7.2²
X² = (24 * 3.5^2) / 7.2^2
X² = 5.67
Pvalue from Chisquare statistic :
P(X² < 5.67) = 0.000042
Pvalue < α ; we reject the Null.
Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

If 2 inches on a map represents 25 miles, how many inches would represent 225 miles?
Answers
Answer:18
Step-by-step explanation:
18 inches represent 225 miles.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
2 inches on a map represents 25 miles.
We have to calculate the value of inches that correspond to 225 miles.
Let x be the unknown value of inches that correspond to 225 miles.
Using proportional concept,
2 : 25 = x : 225
This can also be written as,
2 / 25 = x / 225
Cross multiplying,
2 × 225 = 25 x
x = (2 × 225) / 25
x = 18
Hence the value of the unknown inch is 18 inches.

The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who is 30-49 years old is chosen at random, what is the probability that they have completed a bachelor's degree and no more? Round your answer to the nearest thousandth.
Answers
Answer:
If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.
Step-by-step explanation:
Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:
30-39 Bachelor's degree = 1576
40-49 Bachelor's degree = 443
30-39 Total = 4062
40-49 Total = 2869
4062 + 2869 = 100
1576 + 443 = X
6931 = 100
2019 = X
2019 x 100/6931 = X
201900/6931 = X
29,129 = X
Therefore, if a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Given the supply and demand functions below, find the demand when p = $12.
S(p) = 5p
D(p) = 120 - 4p
Answers
Answer:
S(p)=$60
D(p)=$72
Step-by-step explanation:
S(p)=5(12)
S(p)=60
D(p)=120-4(12)
D(p)=120-48
D(p)=72
From the supply and demand functions below, the demand at the given price is 72.
Given the following data:
Supply, S(p) = 5pDemand, D(p) = 120 - 4pPrice, P = $12.To determine the demand at the given price:
First of all, we would calculate the quantity of supply by substituting the value of price (P).
For supply:
[tex]S(p) = 5p\\\\S(p) = 5(12)[/tex]
S(p) = 60
For demand:
[tex]D(p) = 120 - 4p\\\\D(p) = 120 - 4(12)\\\\D(p) = 120 - 48[/tex]
D(p) = 72
