Answer:

8 minutes, 30 seconds, by the look of the graph.

Step-by-step explanation:

At a distance of 10 inches, 1 minute has passed.

So multiply that by 8.5, and you have 85 inches travelled over 8 minutes, 30 seconds.

Suppose a normal distribution has a mean of 266 and a standard deviation of

Jet001 [13]

Answer:

P(x>278) is 0.16

Step-by-step explanation:

We are given that a normal distribution has a mean of 266 and a standard deviation of 12.

Mean = $\mu =266$

Standard deviation = $\sigma = 12$

We are supposed to find P(x > 278)

So, Formula : $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{278-266}{12}$

Z=1

Refer the z table for p value

p value = 0.8413

P(x<278) is 0.84

P(x>278)=1-P(x<278)=1-0.84=0.16

Option A is true

Hence P(x>278) is 0.16

If y=2x+3, what is parallel to this?

professor190 [17]

Y=2x+5
Parallel lines have the same slopes, so you only change the 3 to a different number.
You want to start the equation like Y=2x then any number at the end.
