-3 on both sides
7x=14
Divided by 7 on both sides
x=14/7=2
The answer will be x=2

Answer: 5 2/6

Step-by-step explanation: 3 5/6 + 1 3/6 = 5 2/6 because you need to add the pie wholes,(3 + 1) and then you have the fractions, 5/6 + 3/6. So since all you need to make another whole is 1/6 you take it away from 3/6 and give it to 5/6 so now you have another whole. 4 wholes plus 1 new whole is 5 wholes. Since you took 1/6 away from 3/6 you now have 2/6. So 5 wholes and 2/6 were sold.

3 5/6 + 1 3/6 =

3 + 1= = 4

5/6 + 1/6 = 1

3/6 - 1/6 = 2/6

4 + 1 = 5

5 + 2/6 = 5 2/6

Answer: σ: 2.76

Step-by-step explanation:

Count, N: 5

Sum, Σx: 125

Mean, μ: 25

Variance, σ2: 7.6

Steps

look at attached pic for formula

σ^2 = $\frac{Σ(xi - μ)^{2} }{N}$

$\frac{(21 - 25)2 + ... + (29 - 25)2}{5}$

⇒ $\frac{38}{5}$

⇒ 7.6

σ = $\sqrt{7.6}$

⇒ 2.756809750418

⇒ or 2.76

Given:

A figure of a circle and two secants on the circle from the outside of the circle.

To find:

The measure of angle KLM.

Solution:

According to the intersecting secant theorem, if two secant of a circle intersect each other outside the circle, then the angle formed on the intersection is half of the difference between the intercepted arcs.

Using intersecting secant theorem, we get

$\angle KLM=\dfrac{1}{2}(Arc(JON)-Arc(KM))$
