The standard deviation would be A. 2.4
Stels [109]3 years ago
3 0

Answer:

The correct option is A.

Step-by-step explanation:

The given data is

7, 3, 4, 2, 5, 6, 9

The mean of the data is

\bar{x}=\frac{\sum{x}}{n}=\frac{36}{7}=5.142857

The standard deviation of the data is

\sigma=\sqrt{\frac{\sum{(x-\bar{x})^2}}{n-1}

Using the below table put the values in the above formula,

\sigma=\sqrt{\frac{34.85714}{7-1}

\sigma=\sqrt{5.80952381}

\sigma=2.410295378

\sigma\approx 2.4

Therefore the correct option is A.

expeople1 [14]

The monthly payment for the new car is; Choice A; $279. 03

<h3>Percentages</h3>

After the down payment of 30% and financing the 8% TT&L is made; it follows that;

The rest of the payment is;

  • $14,350(1 - 0.38)

  • $14,350(0.62)

Hence, $8,897 is the payment made over the course of the duration at a finance rate of 3.16%.

Ultimately, the monthly payment is; $8,897 × 0.0316 = $279.03

2a+6b=100<br> what is 5a+15b=?
algol [13]

Answer:

Step-by-step explanation:Simplifying

2a + 6b = 100

Solving

2a + 6b = 100

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-6b' to each side of the equation.

2a + 6b + -6b = 100 + -6b

Combine like terms: 6b + -6b = 0

2a + 0 = 100 + -6b

2a = 100 + -6b

Divide each side by '2'.

a = 50 + -3b

Simplifying

a = 50 + -3b
