Answer:

x= -9

Step-by-step explanation:

-x+3=2(x+15)

-x+3=2x+30

-x-2x+3=30-3

-3x=30-3

A density curve for all the possible temperatures between 0 degrees F and 40 degrees F is a rectangle. What is the height of the

Eddi Din [679]

Answer:

Concept: Higher Level Mathematics

You have a density curve, aka probability
You are asked to find the height
Hence 0-40F has 40 total integers or values of X(probability)
Hence you have a total Area of
$\binom{40}{0}$
Integrate f(x) to get 0.025.
Hence the answer is A

Solve for e. T=e29 e=±3T√T e=±3T e=±3T√ e=±9T√

Anon25 [30]

Answer:

option (3) is correct.

$e= \pm 3\sqrt{T}$

Step-by-step explanation:

Given $T=\frac{e^2}{9}$

We have to solve for e.

Consider the given statement,

$T=\frac{e^2}{9}$

Cross multiply, we get,

$\Rightarrow 9T={e^2}$

Taking square root both sides , we get,

$\Rightarrow \sqrt{9T}=e$

We know square root of 9 is 3.

$\Rightarrow \pm 3\sqrt{T}=e$

Thus, option (3) is correct.

$e= \pm 3\sqrt{T}$
