Number should be 2 instead of x .
<u>Step-by-step explanation:</u>
Here we have , Jonas has the following data: 2, 5, x, 2, 4, 3. if the average is 3, We need to find what number should be instead x . Let's find out:
We know that
Where is terms and n is the number of terms . Let's find average for 2, 5, x, 2, 4, 3 which is 3 :
⇒
⇒
⇒

Answer:
B. 10.9
Step-by-step explanation:
Area of triangle= 1/2*24*h
∠N=90° ⇒ Area of triangle= 1/2*MN*ON
MN²= h²+(24-7)²
ON²= h²+7²
- 24h=MN*ON
- 24h= √h²+(24-7)²*√h²+7²
- (24h)²=(h²+17²)(h²+7²)
- 576k=k²+289k+49k+289*49
- k²-238k+14161=0
The function would be f (x) = 0.4x - 4.
Explanation
We can see that this is linear, since it increases at a constant rate. We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4
We use point-slope form to write the initial equation:
y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)
Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4
Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
