Solve the linear equation:<br><br> 3.4 + 2(9.7 – 4.8x) = 61.2

Ganezh [65]

Answer:

- 4

Step-by-step explanation:

(2*(Rationalize(9.7)-Rationalize(4.8x)))==Rationalize(61.2)-Rationalize(3.4)

Rationalize(18.4)-Rationalize(2.8x)

==Rationalize(57.8)

-Rationalize(2.8x)==Rationalize(57.8)-Rationalize(18.4)

x= 38.4÷-2.8

:x= -4

An account is opened with $7,595.96 with a rate of increase of 2% per year. After 1 year, the bank account contains $7,746.90. A

Sav [38]

Answer:

It's C

Step-by-step explanation:

y = 7,595.96(1.02)x

the initial beginning value times .02 after adding 1 to it so you would get 1.02 instead since it's an increase raised by x which indicates how many years it was to reach the new value.

Answer:

The standard deviation of the age distribution is 6.2899 years.

Step-by-step explanation:

The formula to compute the standard deviation is:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

The data provided is:

X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}

Compute the mean of the data as follows:

$\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}$

$=\frac{1}{11}\times [19+19+21+...+40]\\\\=\frac{299}{11}\\\\=27.182$

Compute the standard deviation as follows:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

$=\sqrt{\frac{1}{11-1}\times [(19-27.182)^{2}+(19-27.182)^{2}+...+(40-27.182)^{2}]}}\\\\=\sqrt{\frac{395.6364}{10}}\\\\=6.28996\\\\\approx 6.2899$

Thus, the standard deviation of the age distribution is 6.2899 years.

When this 3 digit number is rounded to the nearest hundred it rounds to 900. The digit in the ones is the fifth odd number you c

Vilka [71]

The first digit is 9 or 8.
The fifth odd number you count beginning with one is 9.
Let the middle number be x.
If the first number is 8, then 8 + x + 9 = 22 => 17 + x = 22 => x = 22 - 17 = 5. then the number is 859 which approximates to 900 to to the nearest hundred.
If the number is 9, then 9 + x + 9 = 22 => 18 + x = 22 => x = 22 - 18 = 4, then the number is 949, which also approximates to 900 to the nearest hundred.

Therefore, the required number is 859 or 949.
