please help me don't put nothing if you really don't kno it

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

$8,900

Answer:

197

Step-by-step explanation:

Divide 1640 by 25

1640/25=65

Then multiply 65 and 3

65x3=197

Answer:

39% chance for only boys, 61% chance for only girls for the first two questions

the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.

100:224 = 61:x, or 61/100 = x/224

Cross multiply; 100x=13664

Then, divide by 100; x=136.64, or about 137 groups would contain all girls

Step-by-step explanation:

Answer:

39% 61%

Step-by-step explanation:

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

⬆is your answer! hope this helped!!

The steps to simplify the expression is:

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

x² -28y² - 3yx + zx - 4zy

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

We have the Expression:

(x + 4y + z) (x - 7y).

Step 1 :

x (x-7y) + 4y(x- 7y) + z (x- 4y)

Step 2:

x² - 7yx + 4yx - 28y² + zx - 4zy

Step 3:

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
