A company manufactures a large number of rods. The lengths of the rods are normally distributed with a mean length of 4.4 inches

Elza [17]

Answer:

0.78814

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score = 4.0 inches

μ is the population mean = 4.4 inches

σ is the population standard deviation = 0.5 inches

z = 4.0 - 4.4/0.5

z = -0.8

Probability value from Z-Table:

P(x<4.0) = 0.21186

P(x>4.0) = 1 - P(x<4.0)

= 1 - 2.1186

= 0.78814

The probability that the rod you chose will be greater than 4.0 inches is 0.78814.

Find the value of x. A.4 B.5 C.6 D.9

ra1l [238]

The equation should be...

a^2 + b^2 = c^2

x^2 + (x+3)^2 =10.81665383^2

When you plug it in...

6^2 + (6+3)^2 = 117

6^2 + (9)^2 = 117

36 + 81= 117

Find the integral, using techniques from this or the previous chapter. ∫x/25-9x^2 dx.

kipiarov [429]

Answer:

$\frac{x^{2} }{50} - 3x^{3}$ +C

Step-by-step explanation:

we are to find the integral of $\frac{x}{25} -9x^{2}$ dx.

we will integrate by using the principle of integration of a sum or difference of two functions by integrating them separately.

∫x/25-9x^2 dx = $\frac{x^{2} }{2*25}- 9\frac{x^{3} }{3}$ +C

= $\frac{x^{2} }{50}- 3x^{3}$ +C
