To increase sales, an online clothing store began giving a 50% off coupon to random customers Six customers each made purchases from the website the binomial random variable and mean and standard deviation of X is mathematically given as

$X ~ Bin(n = 6, p = 0.2)$

x= 0.9798

<h3>What is a binomial random variable?</h3>

Generally, the equation for is mathematically given as

P(coupon) = 1/5

P(coupon)= 0.2

the binomial distribution

$X ~ Bin(n = 6, p = 0.2)$

Therefore, The mean and standard deviation of X

$пВ = np \\np= 6* 0.2 = 1.2\\$

$x=\sqrt{ np(1 - p)} \\ x=\sqrt{ 6 * 0.2 + (1 -0.2)} \\$

x= 0.9798

In conclusion, mean and standard deviation of X

x= 0.9798

Select the graph of the solution set that would represent the following expression. | x | > 5

ZanzabumX [31]

Answer:

It would be the first graph because |x| >5 is solved in two cases

The first case you keep everything the same, just get rid of the absolute value bars

x>5

The second case, you need to switch the sign and make the 5 negative

x<-5

When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,

You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right

Hope this helps ;)

What is the area of a rectangle with a length of 9

ANEK [815]

Answer:

We are given a length of 9 cm and a width of 4 cm and we are also told that it our shape is a rectangle. This means that we are able to use the rectangle formula which is $A=l*w$ .

Therefore, we can just multiply 9 cm by 4 cm and we get $A = 36\ cm^2$

Which is the best estimate for the diagonal of a rectangle with a width of x and a length of 2x, if x is 1.33?

german

The best estimate for the diagonal of the rectangle is 3 ⇒ B

Step-by-step explanation:

In a rectangle:

The length and the width are perpendicular
The length of its diagonal = $\sqrt{(length)^{2}+(width)^{2}}$ (the diagonal is the hypotenuse of a right triangle whose legs are the length and the width of the rectangle)
