If a=bc-d, find d given that a=-16, b=3, c=5
Andrews [41]

Answer:

<h2>d = 31</h2>

Step-by-step explanation:

a = bc - d

Substitute a = -16, b = 3 and c = 5:

-16 = (3)(5) - d

-16 = 15 - d              <em>subtract 15 from both sides</em>

-16 - 15 = 15 - 15 - d

-31 = -d             <em>change the signs</em>

31 = d

prohojiy [21]

Answer:

P(X \geq 1) = 1-P(X

And we can find the individual probability like this:

P(X=0) = 16C0 (0.5)^0 (1-0.5)^{16-0} = 0.0000153

And replacing we got:

P(X \geq 1) = 1-P(X

Step-by-step explanation:

Assuming the following question: With the salary cap in the NFL, it is said that on any given Sunday any team could beat any other team. If we assume every week of the 16 week season a team has a 50% chance of winning, what is the probability that a team will have at least 1 win?

Previous concepts  

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".  

Solution to the problem

Let X the random variable of interest, on this case we now that:  

X \sim Binom(n=16, p=0.5)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

And we want this probability:

P(X \geq 1)

And using the complement rule we got:

P(X \geq 1) = 1-P(X

And we can find the individual probability like this:

P(X=0) = 16C0 (0.5)^0 (1-0.5)^{16-0} = 0.0000153

And replacing we got:

P(X \geq 1) = 1-P(X

a scientist has two solutions which she has labeled solutions A and solution B each contains salt. she knows that solution A is
loris [4]

Answer

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 180        y = 180 - x

.60x + .85y = .75(180)

.60x + .85y = 135      Multiply both sides of the equation by 100 to remove the decimal points.

60x + 85y = 13500

60x + 85(180 - x) = 13500

60x + 15300 - 85x = 13500

-25x = -1800

x = 72ounces

y = 180 - 72

y = 108 ounces

Kylie explained that (negative 4 x + 9) squared will result in a difference of squares because (negative 4 x + 9) squared = (neg
Eva8 [605]

Given:

The given expression is:

(-4x+9)^2

According to Kylie,

(-4x+9)^2=(-4x)^2+(9)^2

(-4x+9)^2=16x^2+81

To find:

The correct statement for Kylie's explanation.

Solution:

We have,

(-4x+9)^2

According to the perfect square trinomial (a+b)^2=a^2+2ab+b^2.

(-4x+9)^2=(-4x)^2+2(-4x)(9)+(9)^2

(-4x+9)^2=16x^2-72x+81

Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.

Therefore, the correct option is C.
