The mixed number as an improper fraction is 37/8
<h3>How to express the mixed number as an improper fraction?</h3>
The diameter is give as:
Diameter = 4 5/8
Next we convert the above number to an improper fraction
The numerator is calculated as
Numerator = 8 * 4 + 5
This gives
Numerator = 37
Hence, the mixed number as an improper fraction is 37/8

Answer:
The correct option is (C) (2.769, 3.231).
Step-by-step explanation:
The confidence interval for mean when the standard deviation is not known is:
Given:
Compute the critical value as follows:
**Use a <em>t</em>-table.
The 95% confidence interval for true mean length of the bolt is:
Thus, the 95% confidence interval for true mean length of the bolt is (2.769, 3.231).
The correct option is (C).
Answer: B
Step-by-step explanation: because B has 2 points that are able to be plotted because it would be y=2x+0 and 0 is the y intercepts while 2 is the slope.
Given : The Cost of Laptop in 2007 is $1250
Given : The Cost of Laptop in 2009 is $1100
Decrease in Price of Laptop from 2007 to 2009 : (1250 - 1100) = $150
A) Percent Decrease in the Price of the Laptop from 2007 to 2009 is :
Given : Decrease in Price of Laptop from 2009 to 2010 = $165
B) Percent Decrease in the Price of the Laptop from 2009 to 2010 is :
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
