Answer:
Step-by-step explanation:
25=mean of (5th+6th value)
25=1/2*(2x-8+2x+10)
25=1/2*4x+2
4x+2=50
4x=48
x=12

Answer:
Step-by-step explanation:
We have to find the equation of plane that is parallel to the vectors

The plane also passes through the point (2,0,-1).
Hence, the equation of plane s given by:
![\displaystyle\left[\begin{array}{ccc}x-2&y-0&z+1\\3&0&3\\0&1&3\end{array}\right]\\\\=(x-2)(0-3) - (y-0)(9-0) + (z+1)(3-0)\\=-3(x-2)-9y+3(z+1)\\\Rightarrow -3x + 6 - 9y + 3z + 3 = 0\\\Rightarrow 3x + 9y -3z -9 = 0\\\Rightarrow x + 3y -z - 3 = 0](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx-2%26y-0%26z%2B1%5C%5C3%260%263%5C%5C0%261%263%5Cend%7Barray%7D%5Cright%5D%5C%5C%5C%5C%3D%28x-2%29%280-3%29%20-%20%28y-0%29%289-0%29%20%2B%20%28z%2B1%29%283-0%29%5C%5C%3D-3%28x-2%29-9y%2B3%28z%2B1%29%5C%5C%5CRightarrow%20-3x%20%2B%206%20-%209y%20%2B%203z%20%2B%203%20%3D%200%5C%5C%5CRightarrow%203x%20%2B%209y%20-3z%20-9%20%3D%200%5C%5C%5CRightarrow%20x%20%2B%203y%20-z%20-%203%20%3D%200)
It is the required equation of plane.
The recipe makes 8 pancakes.
He wants to make 12 pancakes.
First, find out how many times what he needs is compared to the recipe.
He wants 12 pancakes; the recipe makes 8 pancakes.
12/8 = 1.5
He wants to make 1.5 times the recipe.
Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.
240 g of plain flour.
240 g * 1.5 = 360 g of plain flour
2 egs
2 eggs * 1.5 = 3 eggs
600 ml milk
600 ml * 1.5 = 900 ml
Answer: 360; 3; 900
Answer:
C
Step-by-step explanation:
We want to solve the equation:

Using the quadratic formula. The quadratic formula is given by:

In this case, <em>a</em> = 1, <em>b</em> = 2, and <em>c</em> = 7.
Substitute:

Evaluate:

Simplify the square root:

Hence:
