Answer:
The answer is approximately 1.21.
Step-by-step explanation:
Using a calculator, enter in acos(6/17) or cos^-1(6/17)
theres no link or answer choices but i can give u the definition
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x.
Answer:
x cannot = 3 or -3; solution is x = 7/11.
Step-by-step explanation:
I believe you meant 6 / (x-3) + 5 / (x+3) = 10 / (x^2 - 9). Those parentheses are important, to avoid ambiguity.
Part A:
Then: x cannot be 3, as the first term would then be undefined.
Also: x cannot be -3, as then the 2nd term would be undefined.
Multiply all three terms by the LCD, which is (x-3)(x+3):
6(x+3) + 5(x-3) = 10
Performing the indicated multiplication,
6x + 18 + 5x - 15 = 10. Then 11x + 3 = 10, or 11x = 7, or x = 7/11.
This is the solution (Part B).
Answer:
Option C - Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in
Step-by-step explanation:
We are given;
n = 15
t-value = 1.66
Significance level;α = 0.05
So, DF = n - 1 = 15 - 1 = 14
From the one-sample t - table attached, we can see that the p - value of 0.06 at a t-value of 1.66 and a DF of 14
Now, since the P-value is 0.06,it is greater than the significance level of 0.05. Thus we do not reject the null hypothesis. We conclude that there is not sufficient evidence that the true diameter differs from 0.5 in.
