How many three digit numbers have a 2 as a tens digit??
Answer:
90 numbers
Step-by-step explanation:
Considering the stipulations from the question, the layout for the 3-digit number is:
[tex]\underline{x}\:\underline{2}\:\underline{y}[/tex]
The hundreds digit, [tex]x[/tex], can be any number from 1-9 inclusive, which contains 9 numbers.

It is assumed that the time customers spend in a record store is uniformly distributed between 3 and 12 minutes. Based on this information, what is the probability that a customer will be exactly 7.50 minutes in the record store
Answer:
0% probability that a customer will be exactly 7.50 minutes in the record store.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.
Uniformly distributed between 3 and 12 minutes.
This means that [tex]a = 3, b = 12[/tex]
What is the probability that a customer will be exactly 7.50 minutes in the record store?
Continuous distribution, so:
0% probability that a customer will be exactly 7.50 minutes in the record store.

To explain:The reason for the statement to be incorrect.A person participates in a weekly office pool in which he has one chance in ten of winning the prize. If he participates for five weeks in succession, the probability of winning at least one prize is 5/10.
Answer:
The correct answer is - given approach is incorrect.
Step-by-step explanation:
P = probability of winning = 1/10
q = probability of not winning = 1- (1/10) = 9/10
x = no. of winning
then, p (x ≥ 1) = 1 - p (x < 1)
= 1 - p (x=0)
= 1 - ⁵C₀ (1/10)^⁰ (9/10)^(5-0)
= 1 - (1) (1) (9/10)^5
= 1 - (9/10)^5

O B. y = 4x
O C. y = 2x
o D. y = 18x
O E y=-**
o E. y = - 3
Answer:
Step-by-step explanation:
If (8,2) and (0,0) are points on the line, the slope of the line is (2-0)/(8-0) = ¼.
y = ¼x
y = 1/4x is the equation of the line passing through points (0, 0) and (8, 2)
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
slope of line passing through (0, 0) and (8, 2)
m=2/8
=1/4
Now let us find the y intercept in the equation.
2=1/4(8)+b
2=2+b
b=0

13% VAT is levied on a handicraft after 10% discount. If the VAT amount is Rs 910, then find the marked price and selling price of it with VAT.
Answer:
The marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.
Step-by-step explanation:
Given that 13% VAT is levied on a handicraft after 10% discount, if the VAT amount is $ 910, to find the marked price and selling price of it with VAT the following calculations must be performed:
13 = 910
100 = X
100 x 910/13 = X
91,000 / 13 = X
7000 = X
0.9 = 7000
1 = X
7000 / 0.9 = X
7,777.77 = X
Therefore, the marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.

Answer:
the right answer would be C
Answer:
Step-by-step explanation:
You first need to find the surface area of a completely open cylinder. That formula is
[tex]SA=2\pi rh[/tex] Using 3.14 for π, we find the area of the material that is needed to make this pipe:
SA = 2(3.14)(1)(30)
SA = 188.49 square feet.
If it costs $3.50 per square foot and you have 188.9 square feet, we multiply the cost per square foot times the number of square feet:

if the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?
[tex] \underline{ \huge \mathcal{ Ànswér} } \huge: - [/tex]
Average of b and c is 8, that is
[tex]➢ \: \: \dfrac{b + c}{2} = 8[/tex]
[tex]➢ \: \: b + c = 16[/tex]
[tex]➢ \: \: c = 16 - b[/tex]

If the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?
Step-by-step explanation:
We are given (b+c)/2=8 and d=3b-4.
We are asked to find (c+d)/2 in terms of variable, b.
We need to first solve (b+c)/2=8 for c.
Multiply both sides by 2: b+c=16.
Subtract b on both sides: c=16-b
Now let's plug in c=16-b and d=3b-4 into (c+d)/2:
([16-b]+[3b-4])/2
Combine like terms:
(12+2b)/2
Divide top and bottom by 2:
(6+1b)/1
Multiplicative identity property applied:
(6+b)/1
Anything divided by 1 is that anything:

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeting during the year. Using the 99% level of confidence, what is the confidence interval for the proportion of households represented at a town meeting?
Answer:
Hence the confidence interval is ( 0.6745, 0.7422).
Step-by-step explanation:
Now the given are
Sample size = n = 1200
x = 850
Sample proportion is
[tex]\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083[/tex]
We have to construct 99% confidence interval for the population proportion.
Formula Used:
[tex](\hat{p}-E , \hat{p}+E)[/tex]
Here E is a margin of error.
[tex]E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]
Zc = 2.58
[tex]E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339[/tex]
So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)
= ( 0.6745 , 0.7422).

U.S cities hire about 17,000 police officers per 10,000 residents for a 17/10,000 ratio a new police chief for a city of 35,000 residents wants to match that ratio. How many police officers are needed
Answer: 59,500
Step-by-step explanation:
Given
For 10,000 residents, 17,000 police officers are hired
The ratio of Police officers and citizens is constant
So, for 35,000 citizens suppose x officers are hired
[tex]\Rightarrow \dfrac{17,000}{10,000}=\dfrac{x}{35,000}\\\\\Rightarrow x=1.7\times 35,000\\\\\Rightarrow x=59,500[/tex]
Thus, 59,500 officers are required.
it is found that 4% of watches produced at a particular factory are defective. If 20 watches made at this factory are randomly selected, what is the probbility that at mpst 1 watch in the same sample is found to be defective
Answer:
0.81 = 81% probability that at most 1 watch in the sample is defective.
Step-by-step explanation:
For each watch, there are only two possible outcomes. Either it is defective, or it is not. The probability of a watch being defective is independent of any other watch, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
4% of watches produced at a particular factory are defective.
This means that [tex]p = 0.04[/tex]
20 watches made at this factory are randomly selected
This means that [tex]n = 20[/tex]
What is the probability that at most 1 watch in the same sample is found to be defective?
This is:
[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.04)^{0}.(0.96)^{20} = 0.442[/tex]
[tex]P(X = 1) = C_{20,1}.(0.04)^{1}.(0.96)^{19} = 0.368[/tex]
Then
[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.442 + 0.368 = 0.81[/tex]
0.81 = 81% probability that at most 1 watch in the sample is defective.
