Hey there! I'm happy to help!
AREA
To find the area of a parallelogram, you multiply the base by the height.
12(6)=72
The area is 72 square centimeters.
PERIMETER
The two diagonal sides are 8 cm and the two bases are 12 cm.
8+8+12+12=40
The perimeter is 40 cm.
Have a wonderful day! :D
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}}](https://tex.z-dn.net/?f=%28%5CBar%7Bx%7D-%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20%2C%20%5C%2C%20%5CBar%7Bx%7D%2B%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20)
where
![\Bar{x}](https://tex.z-dn.net/?f=%5CBar%7Bx%7D)
= 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.
Angles in a triangle add up to 180°, so you can say that xyz = 180. 3 + 3 + 6 = 12, and 180 ÷ 12 = 15. Now, you just multiply 15 by each ratio value, so 15 × 3 = 45, 15 × 3 = 45, and 15 × 6 = 90, so these are the answers. I hope this helps!
For the first group, I would say that each value is separate by 3 from the prior value. For example, 1+3=4 and 4+3=7
For the second one, I would say they are all multiples of 3
3*1=3
3*2=6
3*3=9
Hope this helps
Answer:
the answer is Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(−17/2, -7)
Equation Form:x=-17/2 y=-7
