Answer:
she can buy 3 pieces of candy
Step-by-step explanation:
1. subtract the price of the ticket from $20
20 - 8.5 = 11.5
2. she has $11.50 left. divide that by the price of a piece of candy
11.5 / 3 = 3.83
she cannot buy 0.83 of a piece of candy, so you round down to the nearest whole number, which is 3.
Anyone know how to do this??
Answer:
y = (-1/6)x - 1
Step-by-step explanation:
y = 6x - 2
find the reciprocal of 6 which is -1/6 then find the y-intercept (b)
y = (-1/6)x + b
-2 = (-1/6)(6) + b
-2 = -1 + b
+1 +1
-1 = b
Answer:
should be nigitive
Step-by-step explanation:
Y=mx+b
M- represents the slope and its constant
B- represents the y-intersect

On June 19, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99. After the split, Keisha received a check for a fractional part of a share. What was the amount of that check?
Answer:
$11.33
Step-by-step explanation:
Keisha will own 307 shares after the split. and the amount of check is 11 dollar.
Given that, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, 3+ 2 = 5
Now, let x be the number of shares post split
Then;
3/2 = x/205
x = 3/2 (205)
x = 615/2 = 307.5
Therefore, Keisha will own 307 shares after the split.

Answer: Domain is [1,3], Range is [304,391]
Step-by-step explanation:
Domain is just the x values the table has from lowest to highest. Period is the x values so domain is [1,3]
Range is the y values from lowest to highest the lowest y is 304 and highest is 391, so you use those two numbers to get [304,391]

1. Jack wants to buy a pair of name-brand headphones on a popular auction
website. He enters the brand, make, and model number and searches the site
for what is available. He notices that some headphones are being offered as
"buy now" with a fixed price and others are up for bid in auctions. Below is a
list of all prices at the time he did his search.
$75 $95 $180 $136 $89 $75 $110 $180 $100 $136 $180
$95 $180 $136 $75
$100 $110 $180 $180 $136 $75 $90
a. Construct a frequency distribution for the data.
b. Use the frequency distribution to determine the mean. Round your answer
to the nearest cent.
c. Use the frequency distribution to determine the median and the mode.
Answer:
Mean = 125.136
Median = 110
Mode = 180
Step-by-step explanation:
Given the data:
75 95 180 136 89 75 110 180 100 136 180 95 180 136 75 100 110 180 180 136 75 90
Frequency distribution:
Value(X) ___freq (F) ____cumm frequency
85 _________ 4 _______ 4
89 _________ 1 _______5
90 __________1 _______6
95 __________2 ______ 8
100 _________ 2 ______10
110 __________2______ 12
136 __________4 _____ 16
180 __________6______22
2) Using the frequency distribution :
Mean = Σfx / Σf
[(85*4) + (89*1) + (90*1) + (95*2) + (100*2) + (110*2) + (136*4) + (180*6)]/ 10
= 2753 / 22
= $125.136
Median of grouped data :
Frequency + 1 / 2 = 23/2 = 11.5 th term
The median value = $110
Mode of the data:
Most frequently occurring = 180 (frequency of 6)
The mean of the frequency distribution is $125.136, the median of the frequency distribution is $110, and the mode of the frequency distribution is $180.

Simplify the above expression.
Mean = $125.136
c) The median of the frequency distribution is calculated as:
[tex]\rm Term= Frequency + \dfrac{1}{2}=11.5[/tex]

Point M is on line segment overline LN . Given MN = 3x , LN = 4x + 9 , and LM = 2x + 7 determine the numerical length of LM .
Answer: 11
Step-by-step explanation:just trust me
The numerical length of LM will be 11.
It is given that point M is on line segment overline LN . Also , MN = 3x , LN = 4x + 9 , and LM = 2x + 7.
We have to determine that what will be the numerical length of LM ?
What will be the value of x in equation ; 3x + 2 = 8 ?
The value of x will be 2.
From the question we can get that ,
MN + LM = LN
2x + 7 + 3x = 4x + 9
5x + 7 = 4x + 9
x = 2
Now , we can use the value of x to find out length of LM ;
∵ LM = 2x + 7
⇒ LM = 2 × 2 + 7
⇒ LM = 11.
Thus , the numerical length of LM will be 11.

The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage. The values of the parameters depend on the voltage and temperature; suppose α = 2.6 and β = 220. (a) What is the probability that a specimen's lifetime is at most 250? Less than 250? More than 300? (Round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) What is the probability that a specimen's lifetime is between 100 and 250? (Round your answer to four decimal places.) (c) What value is such that exactly 50% of all specimens
Answer:
a
P(X \le 250 ) = 0.7564 [/tex] , [tex]P(X < 250 ) = 0.7564 [/tex] ,
[tex]P(X < 300 ) = 0.09922 [/tex]
b
[tex]P(100 < X < 250 ) =0.644 [/tex]
c
[tex] x = 192.1 [/tex]
Step-by-step explanation:
From the question we are told that
The value for [tex]\alpha = 2.6[/tex]
The value for [tex]\beta = 220[/tex]
Generally the Weibull distribution function is mathematically represented as
[tex]F( x , \alpha , \beta ) = \left \{ 0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x < 0} \atop { 1- e^{-(\frac{x}{\beta } )^{\alpha } }}\ \ \ \ \ \ x \ge 0} \right[/tex]
Generally the probability that a specimen's lifetime is at most 250 is mathematically represented as
[tex]P(X \le 250 ) = F(250, 2.7 , 220 )[/tex]
[tex]P(X \le 250 )=1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]
[tex]P(X \le 250 ) = 1 - 0.2436[/tex]
[tex]P(X \le 250 ) = 0.7564 [/tex]
Generally the probability that a specimen's lifetime is less than 250
[tex]P(X < 250 ) = F(250, 2.7 , 220 )[/tex]
[texP(X < 250 ) =1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]
[tex]P(X < 250 ) = 1 - 0.2436[/tex]
[tex]P(X < 250 ) = 0.7564 [/tex]
Generally the probability that a specimen's lifetime is more than 300
[tex]P(X > 300 ) = 1- p(X \le 300 )[/tex]
[tex]P(X > 300 ) = 1- F(300, 2.7 , 220 )[/tex]
[texP(X < 300) =1- [1 - e^{- (\frac{300}{220} )^{2.7}}][/tex]
[tex]P(X < 300 ) = 0.09922 [/tex]
Generally the probability that a specimen's lifetime is between 100 and 250 is
[tex]P(100 < X < 250 ) = P(X < 250) - P(X < 100)[/tex]
=> [tex]P(100 < X < 250 ) =F(250 , 2.7 , 220 ) - F(100 , 2.7 , 220 ) [/tex]
=> [tex]P(100 < X < 250 ) =(1 - e^{-(\frac{250}{220})^{2.7}}) - (1 - e^{-(\frac{100}{220})^{2.7}}) [/tex]
=> [tex]P(100 < X < 250 ) = (1 - 0.244 ) - (1- 0.888)[/tex]
=> [tex]P(100 < X < 250 ) =0.644 [/tex]
Generally the value such that exactly 50% of all specimens
[tex]P(X > x) = 1-P(X < x) = 0.50[/tex]
=> [tex]P(X > x) = 1- (1 - e^{- (\frac{x}{220}) ^{2.7}}) = 0.50[/tex]
=> [tex] P(X> x ) = e^(- \frac{x}{20})^{2.7} = 0.50 [/tex]
=> [tex] P(X> x ) = (- \frac{x}{20})^{2.7} = ln0.50 [/tex]
=> [tex] P(X> x ) = \frac{x}{20} =[ -ln0.50 ] ^{frac{1}{2.7}}[/tex]
=> [tex] x = 220[ -ln0.50 ] ^{frac{1}{2.7}}[/tex]
=> [tex] x = 192.1 [/tex]

Some equations have the form y=kxy=kx, where kk is a number.
Which equation CANNOT be written in the form y=kxy=kx?
Answer:
[tex]x = 4y[/tex]
Step-by-step explanation:
Given
[tex]y = kx[/tex]
See attachment for options.
Required
Determine which of the options answers the question
Analyzing the option one after the other:
[tex]\frac{x}{y} = 4[/tex]
Multiply through by y
[tex]y * \frac{x}{y} = 4 * y[/tex]
[tex]x = 4y[/tex]
Divide through by 4
[tex]\frac{x}{4} = \frac{4y}{4}[/tex]
[tex]\frac{x}{4} = y[/tex]
This can be rewritten as
[tex]y = \frac{x}{4}[/tex]
[tex]y = \frac{1}{4} x[/tex]
By comparison with [tex]y = kx[/tex]
we have:
[tex]y = y[/tex]
[tex]x = x[/tex]
[tex]k = \frac{1}{4}[/tex]
Hence: this answers the question.

in Haritha haram,108,84 and 60 saplings of mango guava and sapota are supplied .find the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted
Answer: 21
Step-by-step explanation:
Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.
Since, 108 = 2 x 2 x 3 x 3 x 3
84 = 2 x 2 x 3 x 7
60 = 2 x 2 x 3 x 5
HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]
= 12
Greatest number of plants in each row = 12
Number of rows for mango = [tex]\dfrac{108}{12}=9[/tex]
Number of rows for guava = [tex]\dfrac{84}{12}=7[/tex]
Number of rows for sapota = [tex]\dfrac{60}{12}=5[/tex]
Total rows = 9+7+5= 21
Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted = 21
