You are told P is true and q is false.

The V means or, so if either P is true or q is false the truth value would be true.

The answer would be T F → T , because the P is T, the q is F, which makes the statements true T

Answer:

If p is a true statement and q is false, what is the truth value of p ∨ q?

<u>T F → T</u> T F → F F T → T F T → F

Assume that trees are subjected to different levels of carbon dioxide atmosphere with 7% of the trees in a minimal growth condit

taurus [48]

Answer: The mean and standard deviation are 567.2 and 89.88 resp.

Step-by-step explanation:

Since we have given that

For 370 parts per million = 7% = 0.07

For 440 parts per million = 10% = 0.10

For 550 parts per million = 49% = 0.49

For 670 parts per million = 34% = 0.34

So, Mean of the carbon dioxide atmosphere for these trees would be

$E[x]=370\times 0.07+440\times 0.1+550\times 0.49+670\times 0.34=567.2$

And

$E[x^2]=370^2\times 0.07+440^2\times 0.1+550^2\times 0.49+670^2\times 0.34=329794$

So, Variance would be

$Var\ x=E[x^2]-E[x]^2=329794-567.2^2=8078.16$

So, the standard deviation would be

$\sigma=\sqrt{8078.16}=89.88$

Hence, the mean and standard deviation are 567.2 and 89.88 resp.

Write an equation of the line with the given slope and y-intercept,(4,3) and (0,1)

PSYCHO15rus [73]

Answer:

y=1/2x+1

Step-by-step explanation:

First use slope formula.

$\frac{y2-y1}{x2-x1}$

Plug in the information needed.

$\frac{1-3}{0-4}=\frac{-2}{-4}=\frac{1}{2}$

The slope is $\frac{1}{2}$ .

Now, use point-slope formula.

y-y1=m(x-x1)

Plug in the information needed.

y-3=1/2(x-4)

y-3=1/2x-2

y=1/2x+1

The equation of the line in slope-intercept form is y=1/2x+1.

Hope this helps!

If not, I am sorry.

6. Evaluate the expression for the value of the variable. 1/3x + 5 x = -6

taurus [48]

Answer:

$\frac{1}{3} x + 5x = - 6 \\ \frac{16}{3} x = - 6 \\ x = \frac{ - 6}{ \frac{16}{3} } \\ x = \frac{ - 9}{8}$
