The t value for a 99% confidence interval estimation based upon a sample of size 10 is
Aliun [14]
Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.

Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as
(\Bar{x}- t\frac{s}{\sqrt{n}} , \, \Bar{x}+ t\frac{s}{\sqrt{n}}
where
 \Bar{x} = sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n =  sample size.

When reading the t-value, (n-1) is called the df or degrees of freedom.

3y - 5x = 9<br> Y= -5/3x-12<br> Are the parallel
bija089 [108]

Answer:

Both lines are not parallel

Step-by-step explanation:

Given as :

Two lines equation are as :

3y - 5x = 9   And  y = - \frac{5}{3}x - 12

First line is now written in eq y = mx + c

Or,    3y = 5x + 9

Or,      y = \frac{5}{3}x +  \frac{9}{3}

So, Slop of this line ( m 1 ) =  \frac{5}{3}

     slop of second line ( m 2) is  \frac{- 5}{3}

∵ The slop of both lines are not equal , so the line are not parallel to each other .

Hence Both lines are not parallel     Answer

Answer:

○ B. 525\:square\:units

Step-by-step explanation:

All sides meet at right angles, so when split up, you have this:

525 = 98 + 21 + 154 + 252 = 7 \times 14 + 3 \times 7 + 11 \times 14 + 9 \times 28
