Solve the formula for x.<br> S=2πzx+7πz2

Lubov Fominskaja [6]

Answer:

<u>Given:</u>

S = 2πzx + 7πz²

<u>Isolate x:</u>

2πzx = S - 7πz²

<u>Divide both sides by 2πz:</u>

x = (S - 7πz²)/(2πz)

x = S/(2πz) - 3.5z

Which is shorter, 60 meters or 600 centimeters?

Flura [38]

Your answer would be 600 centimeters. If you look at a ruler you'll see that there are centimeters and no meters because you'll need 100 cm.

In a production process, the probability of manufacturing a defective rear view mirror for a car is 0.075. Assume that the quali

Leviafan [203]

Answer:

The probability that the 3rd defective mirror is the 10th mirror examined = 0.0088

Step-by-step explanation:

Given that:

Probability of manufacturing a defective mirror = 0.075

To find the probability that the 3rd defective mirror is the 10th mirror examined:

Let X be the random variable that follows a negative Binomial expression.

Then;

$X \sim -ve \ Bin (k = 3 , p = 0.075)\\ \\ P(X=x)= \bigg (^{x-1}_{k-1}\bigg)\times P^k\times (1-P)^{x-k}$

$= \bigg (^{10-1}_{3-1}\bigg)\times 0.075^3\times (1-0.075)^{10-3}$

$= \bigg (^9_2\bigg)\times 0.075^3\times (1-0.075)^{7}$

$= \dfrac{9!}{2!(9-2)!}\times 0.075^3\times (0.925)^{7}$

$= \dfrac{9*8*7!}{2!(7)!}\times 0.075^3\times (0.925)^{7}$

= 0.0087999

≅ 0.0088
