The larger of two numbers is 5 more than the smaller. The smaller number plus the larger equals 100. Find the number.
I am Lyosha [343]

Answer:

Smaller number-47.5

Larger number-52.5

Step-by-step explanation:

We will make the smaller number x. If the smaller number is x, then the larger number will be equal to x+5. We also know that when we add the two numbers, we get 100. We can make the equation

x+x+5=100

100-5=95

2x=95

95/2=47.5

x=47.5

The smaller number equals 47.5 and the larger number is 47.5+5 which equals 52.5

If a circle has a Diameter of 4m and a Radius of 4 units. Then what is Circumference and Area of the circle?
Fiesta28 [93]

Answer & Step-by-step explanation:

Circumference=d\pi \\Area=r^2\pi

The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.

Circumference=(8)\pi

Circumference=25.12

So, the circumference of the circle is 25.12 m.

Area=(4)^2\pi

Area=16\pi

Area=50.24

So, the area of the circle is 50.24 units².

What is the relationship between the variance and standard deviation? variance is the positive square root of the standard devia
lana [24]

Variance of a continuous random variable X is defined as

\int\limits_D {(x-\mu)^2f(x)} \, dx

Standard deviation is defined as

\sigma =  \sqrt{Var(X)}

Hence standard deviation is the positive square root of variance.
