I believe it is 8x.

Use the formula A=1/2(b*h)

A=1/2(4x(5x-1))
A=1/2(20x-4x)
A=1/2(16x)
A=8x

A clock has a diameter of 16 cm. How long is the metal band around it?

kramer

Answer:

The length of metal band around the given clock is 50. 24 cm.

Step-by-step explanation:

Here, the diameter of given clock = 16 cm

Now, Diameter = 2 x Radius

So, Radius = D/2 = 16 cm/2 = 8 cm

⇒The radius of the clock = 8 cm

Now, The metal Band around it = The CIRCUMFERENCE of the watch

Circumference of the clock = 2 π r

= 2 x ( 3.14) x ( 8) = 50.24 cm

or, C = 50.24 cm

Hence, the length of metal band around the given clock is 50. 24 cm.

A survey was taken of students in math classes to find out how many hours per day students spend

Hoochie [10]

Answer:

1. Mean, because there are no outliers that affect the center

Step-by-step explanation:

Second period: 3,2,3,1,3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2

Sorted values : 0, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4

The mean = ΣX / n

n = sample size, n = 15

Mean = 34 / 15 = 2.666

The median = 1/2(n+1)th term.

1/2(16)th term = 8th term.

The 8th term = 2

The best measure of centre is the mean because the values for the second period has no outliers that might have affected the centre of the distribution.

Both interquartile range and standard deviation are measures of spread and not measures of centre.

The graph of ƒ(x) = -√x is shifted to the right five units. The domain of the function represented by this graph is x ≥>≤<

Mars2501 [29]

Answer:

Domain = [5,∞)

Step-by-step explanation:

Given: $f(x)=-\sqrt{x}$

We are given that f(x) is shifted right by 5 units.

Rule : f(x)→f(x-b)

The graph f(x) shifted b units right

So, using rule : $-\sqrt{x}$ → $-\sqrt{x-5}$

So, $g(x)=-\sqrt{x-5}$

Now to find domain:

$x-5>0$

$x>5$

So, Domain = [5,∞).
