Suppose that y varies inversely with x, and y = 0.2 when x = 2. What is an equation for the inverse variation?

1 answer:

4 0

If y varies inversely with x:
y = k / x
0.2 = k / 2
k = 2 * 0.2
k = 0.4
Answer:
The equation for the inverse variation is:
y = 0.4 / x

The weights of certain machine components are normally distributed with a mean of 8.04 g and a standard deviation of 0.08 g. Fin

NISA [10]

Answer:

The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Step-by-step explanation:

We are given that

Mean, $\mu=8.04 g$

Standard deviation, $\sigma=0.08g$

We have to find the two weights that separate the top 3% and the bottom 3%.

Let x be the weight of machine components

$P(Xx_2)=0.03$

$P(X$

=0.03

From z- table we get

$P(Z1.88)=0.03$

Therefore, we get

$\frac{x_1-8.04}{0.08}=-1.88$

$x_1-8.04=-1.88\times 0.08$

$x_1=-1.88\times 0.08+8.04$

$x_1=7.8896$

$\frac{x_2-8.04}{0.08}=1.88$

$x_2=1.88\times 0.08+8.04$

$x_2=8.1904$

Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

"If a = − 9 and b = − 6, show that (a−b) ≠ (b−a)."

denis-greek [22]

Answer:

Step-by-step explanation:

LHS a - b = -9 - (-6) = -9 +6 = -3

RHS b-a = -6 - (- 9) = -6 +9 = 3

as LHS not equal to RHS

a-b not equal to b-a

Thus proven
