Answer:
x - 5 = 14, x = 19
Step-by-step explanation:
five (5) less than (-) a number (x) is(=) fourteen (14)
<em>the wording makes it complicated but when you analyze it, you'll comprehend it clearer</em>
1 Simplify
3x^2/10 x 9x^3 x 25
2 Simplify 10\times 9x^3\times 25 to <span>2250x^3
3x^2/2250^3
</span>3 Take out the constants
3/2250 x x^2/x^3
4 Simplify 3/2250 to 1/750
1/750 x x^2/x^3
5 Simplify
x^2/750x^3
6 Use Quotient Rule: x^a/x^b = x^a-b
<span>x^2-3/750
</span>7 Simplify 2-3 to <span>-1
x^-1/750
</span>8 Use <span>Negative Power Rule: x^-a = 1/x^a
1/x /750
</span>9 Simplify
1/750x is the answer. :)
I hope this help[s. :)
I'd say the answer to the first question is D) 0 to 4 with intervals of 0.2.
Because, you can't just have 1 to 4, as some of the numbers are less than 1. Of course you can't have 2 to 5 either. And intervals of 2 would be too messy.
For the second question:
I believe the answer is A. Because it's obvious that there IS one outlier, and it looks like there are two clusters.
So, the answers are: A) and D).
Answer:
b. 8.29
Step-by-step explanation:
Hello!
The objective is to study both processes to see if there is any difference between the costs of manufacturing.
An ANOVA was conducted for the variable:
Y: cost of manufacturing automobile transmissions
Factor: Process
Treatments: 1 and 2
The statistic for this test is
Where
k= number of treatments
n= total number of observations
Degrees of freedom of the treatments: k-1= 2-1= 1
Degrees of freedom of errors: n-k= 20-2= 18
The critical region for this analysis is <u>always</u> one tailed to the right.
I hope this helps!
