I don’t know how to add intergers.How do I.it is too hard for me
Norma-Jean [14]
A positive + A positive = A positive (1+2=3)

A negative + A negative = A negative (-1+(-2)=-3)

Adding a negative is like subtracting a positive (1 + (-2) = -1) this is equal to (1 - 2 = -1)

Adding a positive is like subtracting a negative (-1 + 2 = 1)

The automatic opening device of a military cargo parachute has been designed to open when the parachute is 135 m above the groun
laiz [17]

Answer:

the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes is 0.4215

Step-by-step explanation:

Let consider Q to be the opening altitude.

The mean μ = 135 m

The standard deviation = 35 m

The probability that the equipment damage will occur if the parachute opens at an altitude of less than 100 m can be computed as follows:

P(Q

P(Q

P(Q

P(Q

If we represent R to be the number of parachutes which have equipment damage to the payload out of 5 parachutes dropped.

The probability of success = 0.1587

the number of independent parachute n = 5

the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes can be computed as:

P(R ≥ 1) = 1 - P(R < 1)

P(R ≥ 1) = 1 - P(R = 0)

The probability mass function of the binomial expression is:

P(R ≥ 1) = 1 - (^5_0)(0.1587)^0(1-0.1587)^{5-0}

P(R ≥ 1) =1 - (\dfrac{5!}{(5-0)!})(0.1587)^0(1-0.1587)^{5-0}

P(R ≥ 1) = 1 - 0.5785

P(R ≥ 1) = 0.4215

Hence, the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes is 0.4215

What is the distance between (-11, -20) and (-11, 5)?
PolarNik [594]
The distance between (-11, -20) and (-11,5) is 25. Since both of the x values are the same, we know that they are both on the same x line. For the y values, -20 and 5, Their difference from each other is 25. Therefore, the distance between those coordinates are 25.
