The weight of corn chips dispensed into a 14-ounce bag by the dispensing machine has been identified as possessing a normal dist

mamaluj [8]

The probability that a normally distributed dataset with a mean, μ, and statndard deviation, σ, exceeds a value x, is given by

$P(X\ \textgreater \ x)=1-P(X\ \textless \ x)=1-P\left(z\ \textless \ \frac{x-\mu}{\frac{\sigma}{\sqrt{n}}} \right)$

Given that the weight of corn chips dispensed into a 14-ounce bag by the dispensing machine is a normal distribution with a mean of 14.5 ounces and a standard deviation of 0.2 ounce.

If 100 bags of chips are randomly selected the probability that the mean weight of these 100 bags exceeds 14.6 ounces is given by

$P(X\ \textgreater \ 14.6)=1-P\left(z\ \textless \ \frac{14.6-14.5}{\frac{0.2}{\sqrt{100}}} \right) \\ \\ =1-P\left(z\ \textless \ \frac{0.1}{\frac{0.2}{10}} \right)=1-P\left(z\ \textless \ \frac{0.1}{0.02} \right) \\ \\ =1-P(z\ \textless \ 5)=1-1=0$

Therefore, the probability that the mean weight of these 100 bags exceeds 14.6 ounces is 0.

What is the force exerted on an object with a mass of 20 kg and an acceleration of 6 m/s2?

OverLord2011 [107]

Answer:

F = 120 N

Step-by-step explanation:

Given that,

The mass of the object, m = 20 kg

Acceleration of the object, a = 6 m/s²

We need to find the force exerted on an object. The force exerted on an object is given by :

$F=ma\\\\F=20\ kg\times 6\ m/s^2\\\\F=120\ N$

So, the required force exerted on the object is 120 N.

Simplify the expression: (3m + 1)(2)

BARSIC [14]

Answer:

6m + 2

Step-by-step explanation:

To simplify the expression you must have to use the distributive property:

(3m + 1)(2)

2 x 3m = 6m

2 x 1 = 2

6m + 2

Nataliya [291]

Answer:

See explanation below

Step-by-step explanation:

There are two ways of interpreting Q unless P.

One of them is: if not P, then Q.

The other one is: if P, then not Q.

Let's write the sentences both ways

If not P, then Q

Original sentence: “I will go shopping, unless it rains.”

If it does not rain, then I will go shopping.

Original sentence: “The function f is continuous, unless x<2”

If x greater or equal than 2, then f is continuous.

If P, then not Q

Original sentence: “I will go shopping, unless it rains.”

If it rains, then I will not go shopping

Original sentence: “The function f is continuous, unless x<2”

If x<2, then f is not continuous.
