Answer:
D. Makes both the top and bottom inequalities true
Step-by-step explanation:
System of linear inequalities
Consider these two inequalities:
2x+3y > 20
3x-2y > 5
The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because
2*3+3*5=21 and it's effectively greater than 20.
But that pair makes the second inequality false, since
3*3-2*5=-1 is not greater than 5.
Thus, the pair (3,5) is not part of the solution.
If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.
Thus, the correct answer to the question is
D. Makes both the top and bottom inequalities true

P= 2/ + 2w Find The Width
9514 1404 393
Answer:
W = P/2 -L
Step-by-step explanation:
Divide by 2 and subtract L.
P = 2L +2W
P/2 = L +W
P/2 -L = W
The width is ...
W = P/2 -L

∠K = ∠N
20x -10 = 15x +15
5x = 25 . . . . . . . . . . add 10-15x
x = 5 . . . . . . . . . . . . divide by 5
Then the side lengths are ...
JK = (4x -4) ft = (4·5 -4) ft = 16 ft
KL = (5x +1) ft = (5·5 +1) ft = 26 ft
And the perimeter is the sum of side lengths:
16 ft + 26 ft + 40 ft = 82 ft
The perimeter of each pool is 82 feet.

According to the Vivino website, the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is $32.48. A New Englandâbased lifestyle magazine wants to determine if red wines of the same quality are less expensive in Providence, and it has collected prices for 56 randomly selected red wines of similar quality from wine stores throughout Providence. The mean and standard deviation for this sample are $30.15 and $12, respectively.
Required:
a. Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48.
b. Using the sample from the 60 bottles, what is the test statistic?
c. At α = 0.05, what is your conclusion?
Answer:
a
The null hypothesis is [tex]H_o : \mu = 32.48[/tex]
The alternative hypothesis is [tex]H_a : \mu < 32.48[/tex]
b
[tex]t = -1.504[/tex]
c
There is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48
Step-by-step explanation:
From the question we are told that
The mean price of is [tex]\mu = \$ 32.48[/tex]
The sample size is n = 56
The sample mean is [tex]\= x = \$30.15[/tex]
The standard deviation is [tex]\sigma = \$12[/tex]
The null hypothesis is [tex]H_o : \mu = 32.48[/tex]
The alternative hypothesis is [tex]H_a : \mu < 32.48[/tex]
Generally the test statistic is mathematically represented as
[tex]t = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]
=> [tex]t = \frac{30.15 - 32.48 }{\frac{12 }{\sqrt{60} } }[/tex]
=> [tex]t = -1.504[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P (t < -1.504 )[/tex]
From the z-table
[tex]P(t < -1.504) = 0.066291[/tex]
So
[tex]p-value = 0.066291 [/tex]
From the value we obtain we see that
[tex]p -value > \alpha[/tex]
Then we fail to reject the null hypothesis
Hence there is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48

50 PONTIS Score for Question 3: ___ of 5 points) 3. Solve the given inequality and graph the solution on a number line. Show your work! -2x + 3 < 5
Answer:
If x equals -1 or anything less than -1, then the inequality statement is false
Step-by-step explanation:
So to find the number x has to be for the statement to be false, we have to find what number x would be to make it so both sides equal the same thing. So in this case, it would be -1 because 5-3 equals 2 and -2x=2 only if x=-1. So anything greater than -1 would make the statement true.

A cyclist travels 10 km from home to the park.
She leaves home at 12:20 and arrives at the park at 12:50.
What is her average speed in km/h?
Answer:
20 km/hr
Step-by-step explanation:
The total time she takes to travel 10 km is 30 minutes of 0.5 hours.
To calculate speed, we can divide the distance traveled by the time it takes.
[tex]s = \frac{10}{0.5} = 20[/tex] km/hr

In an auditorium, the front 39 rows with 53 seats in each row are for kids while all 53 seats in each of the remaining 61 rows are for adults. How many seats are there in the auditorium?
Answer:
The auditorium has a total of 5,300 seats
Step-by-step explanation:
The seats for kids can be calculated by multiplying the number of rows by the number of seats per row:
Seats for kids=39*53 =2,067 seats
The seats for adults are calculated in a similar way:
Seats for adults = 61*53= 3,233 seats
Total seats: 2,067+3,233 = 5,300
The auditorium has a total of 5,300 seats

What is triangle inequality theorem ?
It defines the relationship between the sides `of a triangle .
The triangle inequality theorem states that sum of length of two sides of a triangle is greater than the length of the third side .
a + b > c
correct answer option a) 1

nicholas started a canned food drive at school. the equation representing this is y=235=15, where x is the number of days, and y is the number of cans collected. explain how to determine how many days it would take to collect 2600 cans.
Answer:
195 cans will be left after 10 days
Sample Answer: I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

what is l4x-4l+10=3x
Answer:
x=−6
Step-by-step explanation:
4x−4+10=3x
Step 1: Simplify both sides of the equation.
4x−4+10=3x
4x+−4+10=3x
(4x)+(−4+10)=3x(Combine Like Terms)
4x+6=3x
4x+6=3x
Step 2: Subtract 3x from both sides.
4x+6−3x=3x−3x
x+6=0
Step 3: Subtract 6 from both sides.
x+6−6=0−6
