The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bottle, and x is the number of servings or juice poured from the bottle.
How many servings are in a bottle?
Answer:
There are 16 servings in the bottle.
Step-by-step explanation:
The equation for the amount of juice left in the bottle is:
y = 128 - 8*x
Where x is the number of servings of juice poured from the bottle.
The total number of servings that are in the bottle is the value of x such that we have y = 0 (because in that point, we do not have more juice left)
Then we need to solve:
y = 0 = 128 - 8*x
8*x = 128
now we can just divide both sides by 8
x = 128/8 = 16
There are 16 servings in the bottle.
It is known that when a specific type of radish is grown in a certain manner without fertilizer the weights of the radishes produced are normally distributed with a mean of 40g and a standard deviation of 10g. When the same type of radish is grown in the same way except for the inclusion of fertilizer, it is known that the weights of the radishes produced are normally distributed with a mean of 140g and a standard deviation of 40g. Determine the proportion of radishes grown
Answer: hello your question is incomplete below is the missing part
Determine the proportion of radishes grown without fertilizers with weight less than 50grams
answer : p( x < 50 ) = 0.84
Step-by-step explanation:
Radish grown in without fertilizers ( normally distributed )
mean = 40 g
standard deviation = 10 g
Radish grown with fertilizers ( normally distributed )
Mean = 140 g
standard deviation = 40 g
Determine the proportion of radishes grown without fertilizers with weight less than 50 grams
lets assume x = radish without fertilizers
y = radish with fertilizers
hence
p( x < 50 ) = P ( (x-μ / б) < [tex]\frac{50-40}{10}[/tex] )
= p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )
p( x < 50 ) = 0.5 + 0.3413 = 0.8413

5. Aaron drew a map showing the locations of two cities, Oden and Lundy,
on a grid. Aaron drew a straight line from Oden to Lundy. Which of the
following is closest to the distance between Oden and Lundy along the
straight line? *
Please help quickly!!
Answer:
10 miles
Step-by-step explanation:
Given
The attached grid
Required
The distance between Oden and Lundy
See attachment for modified grid
From the newly attached grid, we have:
[tex]d^2 = 6^2 + 8^2[/tex] ---- Pythagoras theorem
This gives:
[tex]d^2 = 36 + 64[/tex]
[tex]d^2 = 100[/tex]
Take positive square roots of both sides
[tex]d = \sqrt{100[/tex]
[tex]d = 10[/tex]
Hence, the distance is 10 miles

how to find the length of EF?
[tex]CD = \frac{HG + EF}{2} \Leftrightarrow EF = 2CD - HG[/tex]
[tex]2x - 2 = 2x - x + 3\\2x - 2x + x = 3 + 2\\x = 5[/tex]
[tex]EF = 2 * 5 - 2 = 10 - 2 = 8[/tex]
Answer: 8.
Answer:
EF=8
Step-by-step explanation:
HG=x-3
CD=x
EF=2x-2
Since HG is 3 less than CD, EF has to be 3 more than CD
x+3=2x-2
3+2=2x-x
5=x
x=5
HG=2
CD=5
EF=8

How do you write the inverse of the conditional statement belo "'If m<1 = 60°, then <1 is acute. " If m<1 = 60° then <1 is not acute. b If <1 is not acute, then m<1 = 60°. If <1 is acute, then m<1 = 60°. If m <1 = 60° then <1 is not acute.
Answer:
d
Step-by-step explanation:
The inverse of a conditional statement, makes both the hypothesis and conclusion or "p" and "q" negative. In other words, it adds a not to both sides.
So the inverse of "If p, then q" would be "If not p, then not q."
"If the measure of angle 1 does not equal 60 degrees, then angle 1 is not acute."
It is estimated that 52% of drivers text while driving.
A. What is the probability that exactly 3 drivers text while driving if a police officer pulls over five drivers?
B. What is the probability the next driver texting while driving that the police officer pulls over is the fifth driver?
Answer:
a) 0.324 = 32.4% probability that exactly 3 drivers text while driving if a police officer pulls over five drivers
b) 0.0276 = 2.76% probability the next driver texting while driving that the police officer pulls over is the fifth driver.
Step-by-step explanation:
For each driver pulled, there are only two possible outcomes. Either they are texting, or they are not. The probability of a driver being texting is independent of any other drivers. This 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.
It is estimated that 52% of drivers text while driving.
This means that [tex]p = 0.52[/tex]
A. What is the probability that exactly 3 drivers text while driving if a police officer pulls over five drivers?
This is [tex]P(X = 3)[/tex] when [tex]n = 5[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{5,3}.(0.52)^{3}.(0.48)^{2} = 0.324[/tex]
0.324 = 32.4% probability that exactly 3 drivers text while driving if a police officer pulls over five drivers.
B. What is the probability the next driver texting while driving that the police officer pulls over is the fifth driver?
None of the first four([tex]P(X = 0)[/tex] when [tex]n = 4[/tex]), and then the fifth, with 52% probability. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.52)^{0}.(0.48)^{4} = 0.0531[/tex]
0.0531*0.52 = 0.0276
0.0276 = 2.76% probability the next driver texting while driving that the police officer pulls over is the fifth driver.

Sample mean, xbar = Σx / n = 29.167
Rbar = ΣR/ n = 11.4
The R chart control limit is given by :
Rbar(1 - 3(d3/d2))
From the R chart :
d3 = 0.729 ; d2 = 3.735
Hence,
LCL = 11.4(1 - 3(0.729/3.735))
LCL = 11.4(0.4144578) =
LCL = 4.72481892 = 4.72
UCL = 11.4(1 - 3(0.729/3.735))
UCL = 11.4(1.5855421)
UCL = 18.075180 = 18.08

2. According to the chart, 11% of all students at this high school have GPA of 3.5 of higher and 14% have GPAs of 1.5
or lower. What percentage of all students have GPAs between 1.5 and 3.5? Show your work. Do not round your
result.
Answer:
75% of all students have GPAs between 1.5 and 3.5
Step-by-step explanation:
11% of all students at this high school have GPA of 3.5 of higher:
This means that a GPA of 3.5 is in the 100 - 11 = 89th percentile, that is, a student that gets a GPA of 3.5 has a higher GPA than 89% of students.
14% have GPAs of 1.5 or lower.
This means that a GPA os 1.5 is in the 14th percentile, that is, a student that gets a GPA of 1.5 has a higher GPA than 14% of students.
What percentage of all students have GPAs between 1.5 and 3.5?
Percentile of 3.5 subtracted by the percentile of 1.5.
89 - 14 = 75%.
75% of all students have GPAs between 1.5 and 3.5

Rene is in the band. As a part of a fund raiser, she is selling tickets to a spaghetti dinner. The tickets cost $8 for adults and $5 for children. If Rene sold 100 total tickets for a total of $611, how many adult tickets did she sell?
Answer:
76 or 63
Step-by-step explanation:
Given: The tickets cost; Adults = $8, children = $5. Rene sold 100 total tickets for a total of $611
To find: How many adult tickets she sold
Solution: To find how many adult tickets Rene sold, divide the total amount of money made by selling the tickets by the cost for adult tickets
611 ÷ 8 = 76.4
In the closest tens place, Rene sold is 76 adult tickets or even 63
