Answer:
Tstatistic = - 3.068
Step-by-step explanation:
Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%
Mean titanium > 9.5%
Test statistic :
(m - μ) / (s/√n)
From the data: obtain the sample mean and standard deviation
From the data given ;
Calculate the same mean and standard deviation :
Using calculator :
Sample mean (m) = ΣX / n
Sample size (n) = 6
m = 47.1 / 6 = 7.85
Standard deviation (s) :
Using calculator = 1.317
Hence,
(m - μ) / (s/√n)
Tstatistic = (7.85 - 9.5) / (1.317/√6)
Tstatistic = - 1.65 / 0.5376629
Tstatistic = - 3.068

A machine that fills bottles on an assembly line does so according to a normal distribution, where the mean amount of liquid poured into each bottle is 11.95 ounces with a standard deviation of 0.045 ounces. If more than 12.10 ounces is poured into a bottle, it will overflow and waste the liquid.
Required:
What is the probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow?
Answer:
The probability is [tex]P( X > 12.10 ) =0.0004[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 11.95 \ ounce[/tex]
The standard deviation is [tex]\sigma = 0.045 \ ounce[/tex]
Generally the probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow is mathematically represented as
[tex]P( X > 12.10 ) = P( \frac{X - \mu }{\sigma } > \frac{ 12.10 - 11.95}{0.045} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P( X > 12.10 ) = P( Z > 3.33 )[/tex]
From the z table the area under the normal curve to the right corresponding to 3.33 is
[tex]P( Z > 3.33 ) = 0.0004[/tex]
=> [tex]P( X > 12.10 ) =0.0004[/tex]
Can someone help me solve multiple step equations? For example (7t - 2) - (-3t + 1) = -3(1 - 3t)
Answer:
t = 0
Step-by-step explanation:
(7t - 2) - (-3t + 1) = -3(1 - 3t)
because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally
[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]
will be
7t - 2 + 3t - 1 = -3 + 9t
add like terms
10t - 3 = -3 + 9t
subtract 9t from both sides
t - 3 = -3
add 3 to both sides
t = 0

Because to make a scaled copy you have to MULTIPLY or DIVIDE all the lengths of the figure
Find the slope of the line. 2x - 4y = 18
Answer:
The slope would be 1/2.
Step-by-step explanation:
Step one: Subtract 2x from both sides to get, -4y=-2x+18
Step two: Divide -4 from all sides
It is just that simple. Hope this helps. Have an awesome day!!!!!!!

The sum of two integers is 31. The larger of the two integers is
4 more than 2 times the smaller integer. What are the integers?
Answer:
The integers are 9 and 22
Step-by-step explanation:
Step one:
given data
let the smaller integer be x
and the bigger be y
x+y=31-----------1
so
y=(2x+4)
Step two:
put y=(2x+4 in equation 1 we have
x+2x+4=31
3x+4=31
3x=31-4
3x=27
divide both sides by 3
x=27/3
x=9
the smaller integer is 9
the bigger is 2(9)+4= 18+4=22

Jeremiah is saving money from a tutoring job. After the first three weeks, he saved $135. Assume the situation is proportional. Use the unit rate to write an equation relating the amount saved s to the number of weeks w worked. At this rate, how much will Jeremiah save for eight weeks? *
Answer:
After the first 3 weeks Jeremiah saved $135. If the situation is proportional:
$135 : 3 = $ 45. It means that he can save $45 for one week.
Therefore an equation is:
s = 45 * w,
where s is the amount saved and w is the number of weeks.
After 8 weeks :
s = 45 * 8 = $360.
