A 10 2/3 -inch long pipe is cut into 8 equal length pieces. How long is each piece?
Answer:
Each peice is 1 1/3 (4/3) long.
Step by step explanation:
10 2/3 divided by 8
10 2/3 = 32/3
32/3 divided by 8 = 32/3 x 1/8
32 times 1 = 32, 3 times 8 = 24 =32/24
32/24 in simplest form is 4/3 (aka 1 1/3)
Hope this helped! :)

What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
Given that;
A robot can complete 7 tasks in 2/5 hour.
Each task takes the same amount of time.
Now,
Since, 7 tasks = 2/5 hour
So, 1 tasks = 2 / 5×7
= 2 / 35 hour
Thus, The robot take 2 / 35 hour to complete one task.
And, 2/5 hour = 7 tasks
So, 1 hour = 7 x 5 / 2
= 35 / 2
Thus, The robot complete 35/2 tasks in one hour.
Therefore,
a) The robot take 2 / 35 hour to complete one task.
b) The robot complete 35/2 tasks in one hour.

Write an equation of the line, in point-slope form, that passes through the two given points. points: (-3,18). (12,-12)
Answer:
y = -2x + 12
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-12 - 18) / (12 + 3)
-30 / 15
= -2
Then, plug this and a point into y = mx + b and solve for b:
y = mx + b
-12 = -2(12) + b
-12 = -24 + b
12 = b
Then, plug in the slope and b into y = mx + b
y = -2x + 12 is the equation of the line

Step-by-step explanation:
Answer:
42/7 or 6
Step-by-step explanation:
First, let's start off with the top part. 6^2 is 6 times 6, which is 36. 36 + 6 = 42. Now for the bottom part, 4^2 is 4 times 4, which is 16. 3^2 is 9. 16-9=7. 42/7 is the fraction form and if you want it simplified, then it is 6.

Most dermatologists recommend using sunscreens that have a Sun Protection Factor (SPF) of at least 30. One of the authors wanted to find out whether the SPF of sunscreens used by students at her school exceeds this value on average? To collect data, the author surveyed students in her introductory statistics course and found that in a sample of 52 students the mean SPF was 34.55 and the standard deviation of SPF was 20.12. The data were not strongly skewed.
Required:
Use the Theory-Based Inference applet to find and report the 95% confidence interval for the parameter of interest.
Answer:
95% confidence interval = ( 28.9485, 40.1515 )
Step-by-step explanation:
sample size( n ) = 52
mean value ( x )= 34.55
std ( б ) = 20.12
H0 : u ≤ 30
Ha : u > 30 ( claim )
95% confidence interval for mean SPF level ( df = 51 )
= mean value ± [tex](2.0076 + \frac{20.12}{\sqrt{52} } )[/tex]
95% confidence interval = ( 28.9485, 40.1515 )
we cannot reject H0
