When I did the math in my head the fraction I got was 20/100000. 20/100000 as a decimal form is 0.0002.

1 x 1 + 7 x (1/10) + 4 x (1/100) + 7 x (1/1000)

It's in expanded form. If you break it apart...

1x1 = 1 (ones place)
7 x 1/10 = .7 (tenths place)
4 x 1/100 = .04 (hundredths place)
7 x 1/1000 = .007 (thousandths place)

Now if we add the results

1 + .7 + .04 + .007 = 1.747

Multiply: (9x^2y^3)(7xy^2)

MrRissso [65]

Remember
(ab)(cd)=(a)(b)(c)(d)=(ac)(bd),
and
(x^m)(x^n)=x^(m+n)

(9x^2y^3)(7xy^2)=
(9)(x^2)(y^3)(7)(x)(y^2)=
(9)(7)(x^2)(x)(y^3)(y^2)=
(63)(x^3)(y^5)=
63x^3y^5

I will like to know how to solve this

Olenka [21]

x = 2

Collect terms in x to one side of the equation and numeric values on the other side.

1 + 4x = - 5 + 7x ( subtract 7x from both sides )

1 + 4x - 7x = - 5

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 6 ( divide both sides by - 3 )

x = $\frac{- 6}{- 3}$ = 2

A bag contains 40 marbles, 4 of which are blue, 10 are red, 25 are green, and 1 is purple. Shawna takes a marble out of the bag,

Rasek [7]

Answer:

250 green marbles

Step-by-step explanation:

We know that there are 25 green marbles in a bag of 40 marbles. Using this, we can say that the probability of pulling a green marble out of the bag is 25/40, or 5/8. To find out how many green marbles Shawna should expect to pull out of the bag after 400 trials, we have to multiply the amount of trials (400) by the probability of pulling out a green marble (5/8).

400 × 5/8 = (400 × 5)/8 = 2000/8 = 250

Shawna should expect 250 green marbles after 400 trials.

I hope you find this helpful. :)

Suppose that prices of a certain model of new homes are normally distributed with a mean of $150,000. Use the 68-95-99.7 rule to

konstantin123 [22]

Answer:

C. 47.5%

Step-by-step explanation:

The summary of the given statistics include:

mean =150000

standard deviation: 1200

The objective is to use tributed with a mean of $150,000. Use the 68-95-99.7 rule to find the percentage of buyers who paid: between $150,000 and $152,400

The z score formula can be use to calculate the percentage of the buyer who paid.

$z = \dfrac{X - \mu}{\sigma}$
