Answer:
378
Step-by-step explanation:
1 digit numbers - 9
2 digit numbers - 90
Now, subtract the repeating numbers 90-9 = 81
3 digit numbers = 4*9*8 = 288
Distinct numbers = 9+81+288 = 378 numbers

Suppose you add two linear equations that form a system, and you get the result y = −2. How many solutions does the system have?
Answer:
This system will have 1 solution
Step-by-step explanation:
A linear system that has exactly one solution is called a consistent independent system. Consistent means that the lines intersect and independent means that the lines are distinct. Linear systems composed of lines that have the same slope and the y-intercept are said to be consistent dependent systems.

Give two examples of line segments that will make a triangle ?
Answer:
If the length of any one side is greater than the sum of the length of the other two, the line segments cannot be used to create a triangle. It is possible to create a triangle using 3 line segments if the sum of the lengths of any two line segments is greater than the length of the third.

i need help with these 2 questions.
Answer:
Step-by-step explanation:
6). Surface area of a triangular prism = Area of the triangular bases + (Perimeter of the triangular base)×height
Area of one triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}\times 4\times 3[/tex]
= 6 km²
Perimeter of the triangular base = (4 + 3 + 5)
= 12 km
Height of the triangular prism = 7 km
Surface area of the given triangular prism = 2(6) + (12)(7)
= 12 + 84
= 96 km²
7). Surface area of a rectangular prism = 2(lb + bh + hl)
Here, l = Length, b = Width and h = Height
By substituting the values from the given question,
l = 9 in, b = 9 in, h = 4 in
Surface area of the rectangular prism = 2(9×9 + 9×4 + 4×9)
= 2(81 + 36 + 36)
= 2(153)
= 306 in²

We run a terminating simulation 20 replications to estimate the average throughput of a manufacturing system. Suppose that the observed throughputs from these 20 replications are 4, 5, 7, 5, 8, 7, 5, 9, 10, 5, 6, 7, 2, 11, 6, 3, 2, 11, 10, 7. a. (0.1 point) What is the 99% t-confidence interval for the mean throughput
Answer:
[tex]CI =6.5 \± 1.09[/tex]
Step-by-step explanation:
Given
[tex]Data: 4, 5, 7, 5, 8, 7, 5, 9, 10, 5, 6, 7, 2, 11, 6, 3, 2, 11, 10, 7[/tex]
Required
Determine the 99% t-confidence interval
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
[tex]\bar x =\frac{4+ 5+ 7+ 5+ 8+ 7+ 5+ 9+10+ 5+ 6+ 7+ 2+ 11+ 6+ 3+ 2+ 11+ 10+ 7}{20}[/tex]
[tex]\bar x =\frac{130}{20}[/tex]
[tex]\bar x =6.5[/tex]
Calculate the standard deviation
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)}{n}[/tex]
[tex]\sigma =\sqrt{\frac{(4-6.5)^2+ (5-6.5)^2+ ........+ (2-6.5)^2+ (11-6.5)^2+ (10-6.5)^2+ (7-6.5)^2}{20}}[/tex]
[tex]\sigma =\sqrt{\frac{143}{20}}[/tex]
[tex]\sigma =\sqrt{7.15}[/tex]
[tex]\sigma =2.67[/tex]
The z score for 99% confidence interval is: 2.576
The confidence interval is calculated as:
[tex]CI =\bar x \± z * \frac{\sigma}{\sqrt n}[/tex]
[tex]CI =6.5 \± 2.576 * \frac{2.67}{\sqrt {40}}[/tex]
[tex]CI =6.5 \± 2.576 * \frac{2.67}{6.32}}[/tex]
[tex]CI =6.5 \± 1.09[/tex]

Two ride-sharing companies are competing for business in a large city. To help customers compare the companies, a data scientist selects a random sample of 40 completed rides from each of the two companies. From each sample, he computes the mean amount of time that passed between when the request for a pickup was placed and when the customer was picked up. Company A took, on average, 18 minutes to pick up customers with a standard deviation of 4 minutes. Company B took, on average, 12 minutes to pick up customers with a standard deviation of 10 minutes. (a) Construct and interpret a 98% confidence interval for the difference in mean response time for these two ride-sharing companies.
Solution :
Given :
[tex]$n_1 = n_2 = 40$[/tex]
[tex]$\overline X_1 = 18$[/tex]
[tex]$S_1 = 4$[/tex]
[tex]$\overline X_2 = 12$[/tex]
[tex]$S_2 =10$[/tex]
So we want to test :
[tex]$H_0 : \mu_1=\mu_2 $[/tex] vs [tex]$H_1 : \mu_1 \neq \mu_2 $[/tex]
a). For 98% confidence interval :
[tex]$=\left((\overline X_1 - \overline X_2) \pm Tn_1+n_2-2, \alpha / 2 \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}\right)$[/tex]
[tex]$=\left((18-12) \pm 2.375 \sqrt{\frac{4^2}{40}+\frac{10^2}{40}}\right)$[/tex]
[tex]$=(6 \pm 4.0445)$[/tex]
= (1.956, 10.045)
c. Suppose the firm with the 20 percent market share announces a plan
to buy one of the firms with a 5 percent market share. Is the U.S.
Department of Justice likely to challenge the merger? Why or why
not?
The likelihood of a U.S. Department of Justice challenge to the merger would depend on various factors, including market concentration, potential anticompetitive effects, and impact on consumer welfare. Without further information, it is difficult to determine definitively.
Determining whether the U.S. Department of Justice (DOJ) is likely to challenge a merger involves several factors, including market concentration and potential antitrust concerns. In this case, the firm with a 20 percent market share plans to acquire a firm with a 5 percent market share.
The DOJ is more likely to challenge a merger when it raises concerns about potential anticompetitive effects, such as creating or enhancing market power. Market concentration is a key factor in assessing antitrust issues. While a 25 percent combined market share may not necessarily trigger an automatic challenge, the DOJ will consider other factors as well.
To evaluate the likelihood of a challenge, the DOJ will assess the overall market structure, including the level of competition and the presence of other significant competitors. If the merger significantly increases concentration levels and reduces competition in the market, it may raise concerns for the DOJ.
Additionally, the DOJ will examine the potential impact on consumer welfare, pricing, and innovation. If the merger is likely to result in higher prices, reduced choices for consumers, or hinder innovation, it may trigger antitrust scrutiny.
Considering the limited information provided, it is challenging to definitively determine whether the DOJ would challenge the merger. However, a 25 percent combined market share might not necessarily be considered highly concentrated, especially if there are other significant competitors in the market. The DOJ's decision would depend on a comprehensive analysis of the specific market dynamics and the potential effects of the merger on competition and consumer welfare.
Ultimately, the likelihood of a DOJ challenge would require a more detailed examination of the specific market conditions, the potential impacts of the merger, and compliance with antitrust laws and regulations.

In a poll conducted of 10000 people before an election, 5050 people preferred candidate D. What is the probability of seeing such a poll, given that candidate D wins the election with 51% of the vote. Make some reasonable assumptions and use the continuity correction to compute your answer.
Answer:
P ( x < 5050.5 ) ≈ 0.16104
Step-by-step explanation:
Total number of voters ( n ) = 10000
Before election : 5050 people preferred Candidate D ( k ) ≈ 50.1 %
Candidate D eventually wins with 51% of the votes
winning ( p ) = 0.51
Applying continuity correction formula
P ( x < 5050.5 ) ≈ 0.16104

1/2 of a number y is more than 22
Answer:
1/2y > 22
Step-by-step explanation:
I think that's what you were asking, but I'm not sure
So the is more than tells you that you're going to use the greater than sign. and 1/2 of y is 1/2y because of means mulitiplication
hope this helps:)
Answer:
1/2y > 22
Step-by-step explanation:
Write an equation for the number y:
1/2 of y is more than 22
1/2 * y is more than 22 ('of' equals multiply)
1/2y = more than 22 ('is' equals a equal sign)
1/2y > 22 ('more' is greater than and not greater than and equal since it doesn't state anything that it could acctually be equal to)
1/2y > 22
(You can solve for y if you need to find the value of the number)
