Answer:

P(x

Step-by-step explanation:

From the question we are told that

Sample mean \=x=12.4

Standard deviation \sigma=1.2miles\ per\ gallon

Probability of P(x

Generally the equation for P(x is mathematically given as

P(x

P(x

Therefore The probability that a randomly selected truck averages fewer than 10 miles per gallon

P(x

( Help ASAP ) y varies inversely with x. If x is 6.4 when y is 1.5, what is k, the constant of inverse variation?
DiKsa [7]

Answer:

k = 9.6

Step-by-step explanation:

When dealing with inverse variation, the two variables vary in opposite directions. This means that as the first variable increases, second variable decreases and as the first variable reduces,the second variable increases.

Y varies inversely with x.

So as y increases, x reduces and as y reduces, x increases.

We would proceed by introducing a constant of variation, k

y = k/x

From the information given,

The constant of variation = k

The value if x = 6.4

The value of y = 1.5

To find the value of k

y = k/x

k = yx = 1.5 × 6.4

k = 9.6
