Find the area, to the nearest thousandth, of the indicated region of the standard normal distribution. The region where z < −0.38
Answers
The area of the indicated region of the standard normal distribution is 0.3520.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
From the normal distribution table, the region where z < −0.38 = P(z < -0.38) = 0.3520

Robert is comparing prices of boxes of napkins. He sees that 2 boxes of Softeez
napkins are $1. Which of the following has a lower unit price than the Softeez
napkins?
o 12 boxes of napkins for $5.88
o 4 boxes of napkins for $2.04
o 6 boxes of napkins for $3.18
o 8 boxes of napkins for $4.16
Answers
Answer:
12 boxes of napkins for $5.88
Step-by-step explanation:
The softeez napkins are $0.50 each. Each pair of "cheaper" napkins should be at least one cent less than a dollar to be cheaper than the softeez napkins.
Dividing each price by the number of boxes of napkins, we get the price per box - 0.49, 0.51, 0.53, and 0.52 (in that order, going down).
The only ones cheaper than the napkins that are two boxes for a dollar are the first ones, which he can buy two boxes of for $0.98.

A football team charges $30 per ticket and averages 20,000 people per game. Each person spend an average of $8 on concessions.For everydrop of $1 in price,the attendance rises by 800 people.What ticket price should the team charge to maximize total revenue? Calculate the TR max.
Answers
The ticket price that would maximize the total revenue would be $ 23.
Given that a football team charges $ 30 per ticket and averages 20,000 people per game, and each person spend an average of $ 8 on concessions, and for every drop of $ 1 in price, the attendance rises by 800 people, to determine what ticket price should the team charge to maximize total revenue, the following calculation must be performed:
20,000 x 30 + 20,000 x 8 = 760,000 24,000 x 25 + 24,000 x 8 = 792,000 28,000 x 20 + 28,000 x 8 = 784,000 26,000 x 22.5 + 26,000 x 8 = 793,000 27,200 x 21 + 27,200 x 8 = 788,000 26,400 x 22 + 26,400 x 8 = 792,000 25,600 x 23 + 25,600 x 8 = 793,600 24,800 x 24 + 24,600 x 8 = 792,000
Therefore, the ticket price that would maximize the total revenue would be $ 23.

What is the corresponding congruent parts for each segment or angle?
Answers
Answer:
NG ( first and last letter of NBG) = WS ( first and last letter of WTS).
BG = TS
G = S
N =W or NG = WS; BG = TS; G = S; N = W.
Step-by-step explanation:
We use the congruence statement to answer these questions. From the way the congruence statement is written, we can see that N = W (they are in the same relative position in the congruence statement). We also see that G and S are in the same relative position, so G = S.
Since N = W and G = S, this means that NG = WS.
From the congruence statement we can also see that B = T (they are in the same relative position). Since G = S, this means that BG = TS.

Answers
Answer:
Step-by-step explanation:
x - y = 8
2*y = x + 4 Reverse the equation
x + 4= 2y Subtract 4 from both sides
x = 2y - 4
Put that value for x in the first equation
2y - 4 - y = 8 Combine like terms on the ledt
y - 4 = 8 Add 4 to both sides
y = 8 + 4
y = 12
x - y = 8
x - 12 = 8 Add 12 to both sides
x = 8 + 12
x = 20
125x^3-27 factor polynomials
Answers
Answer:
The answer is (5x - 3) (25x² + 15x + 9)
Step-by-step explanation:
125x³ - 27
5 × 5 × 5 × x × x × x - 3 × 3 × 3
Rewrite 125x³ as (5x)³.
(5x)³ - 27
Rewrite 27 as (3)³.
(5x)³ - (3)³
Here, Both terms are perfect cubes, factor using the difference of cube formula,
a³ - b³ = (a - b) (a² + ab + b²)
where,
a = 5x
b = 3
Now,
(5x - 3) [(5x)² + (5x)(3) + (3)²]
Now, Simplify
(5x - 3) (25x² + 15x + 9)
Thus, The answer is (5x - 3) (25x² + 15x + 9)

A consumer group wishes to estimate the proportion of adult Twitter users that get at least some news on Twitter. A poll is conducted and it is found that from a SRS of 1251 adult Twitter users, 641 of them get at least some news on Twitter.
2b) What is the 90% confidence interval for the proportion of adult Twitter users that get at least some news on Twitter. Round to 4 decimal places.
Answers
Applying the steps to find the confidence interval of a proportion, it is found that the 90% confidence interval for the proportion of adult Twitter users that get at least some news on Twitter is (0.4892, 0.5356).
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].
From a SRS of 1251 adult Twitter users, 641 of them get at least some news on Twitter, hence:
[tex]n = 1251, \pi = \frac{641}{1251} = 0.5124[/tex]
90% confidence level
So [tex]\alpha = 0.9[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so [tex]z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 - 1.645\sqrt{\frac{0.5124(0.4876)}{1251}} = 0.4892[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 + 1.645\sqrt{\frac{0.5124(0.4876)}{1251}} = 0.5356[/tex]
The 90% confidence interval for the proportion of adult Twitter users that get at least some news on Twitter is (0.4892, 0.5356).

C. The relationship is linear; y + 2 = -5/4 (x + 9).
D. The relationship is linear; y + 2 = 4/5 (x + 9).
Answers
Answer:
C. The relationship is linear; y + 2 = (-5/4)x - 11.25
Step-by-step explanation:
If the relationship f is linear then its graph is a line D of equation y = ax+b
(-9 ,-2)∈D ⇔ -2 = -9a + b (1)
(-5 , -7)∈D ⇔ -7 = -5a + b (2)
(2)-(1)⇒ -5 = 4a ⇒ a = -5/4
-2 = -9a + b ⇒ -2 = -9(-5/4) + b ⇒ 2 +45/4 = -b ⇒ b = -13.25
then
D : y = (-5/4)x - 13.25 ⇒ y + 2 = (-5/4)x - 11.25
since (-1,-12) and (3,-17) are points of D (easy to check)
then it’s a linear relationship
