A.) 200cm
B.) 206cm

A explanation.) To find the mean, you add all the heights and divide by 5 (how many numbers there are), this gives you 1000 divided by 5, which equals exactly 200cm.

B explanation.) I tried the equation with numbers higher than 202, going up one each time, and 206 was the one that equaled exactly 201.

write an equation in point-slope form of the line that passes through the point (3, 5) and has a slope or -1

frez [133]

Answer:

y = -x + 8

Step-by-step explanation:

m = -1 ; x1 = 3 ; y1 = 5

Slope point form: y - y1 = m(x -x1)

y - 5 = -1(x - 3)

y - 5 = -1x - 3 *(-1)

y - 5 =-x + 3

y = -x + 3 + 5

y = -x + 8

Please help asap! thx

Answer:

y = 0

Step-by-step explanation:

The given sinusoidal equation is $y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right)$

The general form of the sin function is presented as follows;

y = A·sin(B·(x - C)) + D

Where;

A = The amplitude

The period, T = 2·π/B

The frequency, f = B/2·π

C = The horizontal shift

D = The vertical shift

By comparison with the given sine function, we have;

The amplitude, A = 2

The frequency, f = B/2·π = π/2/(2·π) = 1/4

The frequency, f = 1/4 Hz

C = The horizontal shift = 3/(π/2) = 6/π

The vertical shift, D = 0

Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, $y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right)$ , is therefore, the line;

y = 0.

Answer:

$\large \boxed{\sf \ \ 64 \ \ }$

Step-by-step explanation:

Hello,

$2(a+b+c)=(a+b)+(b+c)+(c+a)=4+5+7=16\\\\\text{*** divide by 2 both sides ***}\\\\(a+b+c)=\dfrac{16}{2}=8 \ \ \text{ so...}\\\\(a+b+c)^2=8^2=\large \boxed{64}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
