The distance from earth to the moon is about 22^4 miles.The distance from earth to neptune is about 22^7 miles.Which distance is

fiasKO [112]

You are NOT using scientific notation correctly. When you say 22^4 you are saying 22*22*22*22 which equals 234,256. What you should say is Earth to Moon distance = 22 * 10^4 miles. (To be really precise, it should be expressed as 2.2 * 10^5 miles).

Earth to Neptune distance = 2.2 * 10^8 miles.

2.2 * 10^8 / 2.2 * 10^5 = 1,000. So the Earth to Neptune distance is 1,000 times greater than the Earth to Moon distance.

I need help with this work

Anton [14]

Answer:

Please find the answer in the image attached

Step-by-step explanation:

Here we are asked to solve a pair of linear inequalities.

In order to do so , we are first required to plot the two lines with inequalities taking into considerations.

Hence let us plot

x+2y=-4 and 5x+2y=4

let us first plot x+2y=-4

$y=\frac{-4-x}{2}$

let us plot a table for the same for two random values of x and putting them into above equation

x y

0 -2

2 -3

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

0+2(0)≤-4

0≤-4

Which is not true , Hence we shade the portion divided by our line which does not contain (0,0)

Now let us plot the second line 5x+2y=4

$y = \frac{4-5x}{2}$

let us plot a table for the same for two random values of x and putting them into above equation

x y

0 2

1 -0.5

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

5(0)+2(0)≤4

0≤4

Which is true , Hence we shade the portion divided by our line which does contain (0,0)

Please refer to the image attached with this answer.

now the commonly shaded area as shown in the image will be our solution to the above pair of in equations.

You order fifteen burritos to go from a Mexican restaurant, six with hot peppers and nine without. However, the restaurant forgo

Mrrafil [7]

Answer: 0.936

Step-by-step explanation:

Given : Total burritos ordered = 15

Number of burritos with hot peppers = 6

number of burritos without hot peppers =9

Then , the proportion of burritos with hot peppers= $p=\dfrac{6}{15}=0.4$

The number of burritos picked: n = 3

Then using binomial probability , the probability that at most two have hot peppers is given by:-

$P(x\leq2)=1-P(x=3)\\\\=1-^3C_3(0.4)^3(0.6)^0\\\\=1-(1)(0.4)^3=0.936$

Hence, the required probability = 0.936
