16 is not the solution of the equation because if you replaced W with 16, you would end up with 27 = 26, which is false.

Nady [450]

I am pretty sure the answer is 3.5.

(2+x)5=11

(2+x)=11/5

(2+x)= 5.5

x= 5.5-2

According to the manufacturer of the candy Skittles, 20% of the candy produced are red. If we take a random sample of 100 bags o

WITCHER [35]

Answer:

0.15651

Step-by-step explanation:

This can be approximated using a Poisson distribution formula.

The Poisson distribution formula is given by

P(X = x) = (e^-λ)(λˣ)/x!

P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)

where λ = mean of distribution = 20 red bags of skittles (20% of 100 bags of skittles means 20 red bags of skittles)

x = variable whose probability is required = less than 16 red bags of skittles

P(X < x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to (x-1))

P(X < 16) = Σ (e^-λ)(λˣ)/x! (Summation From x=0 to x=15)

P(X < 16) = P(X=0) + P(X=1) + P(X=2) +......+ P(X=15)

Solving this,

P(X < 16) = 0.15651

What is an equation of the line containing the points (-1,5) and (3,9)

Lady bird [3.3K]

Answer:

y = x+6

Step-by-step explanation:

You can find an equation by using the 2-point form of the equation for a line:

y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

Filling in the given values, we have ...

y = (9 -5)/(3 -(-1))·(x -(-1)) +5

y = (4/4)(x +1) +5 . . . . simplifying a bit

y = x +6

Select the correct answer from the drop-down menu. Find the product. The product of 2/5a2x and -1/5x2a is

valentinak56 [21]

Answer: $-\frac{2}{25}a^{3}x^{3}$

Step-by-step explanation:

1. The problem asked for the product of $\frac{2}{5}a^{2}x$ and $-\frac{1}{5}x^{2}a$ , therefore, you must mutliply them, as you can see below:

2. According the exponents propertiess, when you have a multiplication of two powers that has the equal base, you must add the exponents. THerefore, you have the following result:

$(\frac{2}{5}a^{2}x)(-\frac{1}{5}x^{2}a)=-\frac{2}{25}a^{3}x^{3}$
