I can’t see the photo so I can’t tell you the answer but good luck. Congruent means they look the same I think.
Let's make the mysterious, original price not-so-mysterious by calling it <em>x. </em>245.97 is 3/5 of x.
We can equation this.
245.97 = 3/5x
x = 245.97 / (3/5)
x = 409.95
The answer, I believe, is $409.95. Hope this helps!
Answer:
d. The population standard deviation is known.
Step-by-step explanation:
T-distribution or Z-distribution, which to use?
If we have the population standard deviation is known, we use the z-distribution.
Otherwise, if we only have the standard deviation for the sample, we use the t-distribution.
Which of the following is not appropriate to use the t-confidence interval for
When the population standard deviation is known, so letter d.
We have been given an expression . We are asked to find the value of A when rewrite our given expression as .
To solve our given problem, we will use exponent properties.
Using exponent property , we can rewrite our given expression as:
Now, we will compare our expression with .
Upon comparing with , we can see that .
Therefore, the value of A is .
We can further simplify as:
A slope is the change in position with respect to x and y. Use y2-y1 over x2-x1. The 2s and 1s are supscripts in this equation.
