Answer:

5 - number summary:

Minimum : 664

First quartile : 706

Median : 766

Upper quartile : 810

Maximum : 836

Step-by-step explanation:

Given the data:

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Sorted data :

664, 693, 698, 714, 751, 753, 779, 789, 802, 818, 834, 836

Minimum =664

Lower quartile (Q1) = 1/4(n+1)th term

Q1 = 1/4(13) = 3.25 = (3rd + 4th) = (698 + 714) / 2 = 706

Median (Q2) = 1/2(n+1)th term

Q2 = 1/2(13) = 6.5 = (6th + 7th) = (753 + 779) / 2 = 766

Upper quartile (Q3) = 3/4(n+1)th term

Q3 = 3/4(13) = 9.75 = (9th + 10th) = (802 + 818) / 2 = 810

Maximum = 836

What are the x-coordinates for the maximum points in the function f(x)=4cos(2x-pi) from x=0 to x=2pi?

wel

The maximum value attained by the function will be 4
4 = 4cos(2x - π)
cos(2x - π) = 1
2x - π = 0
x = (nπ)/2
From x = 0 to x = 2π, n = 1, 2, etc
The equation will yield +4 for odd values of n and -4 for even values of n

The angles of elevation froma point X to the top of flagpoles A and B are 35* and 45* respectively. If X lies in the middle of t

BartSMP [9]

Let AB = t. And since X lies in the middle, so AX=BX = t/2 .

Let the height of the smaller flagpole is AO and of larger flagpole is BP .

Using tangent ratio rule in each triangle, we will get

$tan 35 =\frac{AO}{t/2} , tan 45= \frac{BP}{t/2} // AO = \frac{t*tan35}{2}, BP=\frac{t*tan45}{2}$

And there ratio is

$\frac{AO}{BP}= \frac{tan 35}{tan 45}=\frac{0.7}{1}$

1/2x-5=10-3/4x please helpppppp

GarryVolchara [31]

Answer:

x=12

Step-by-step explanation:

1/2x - 5 = 10 - 3/4x ---> move like terms to the same side

1/2x + 3/4x = 10 + 5 ---> calculate

5/4x = 15 ---> multiply both sides by 4/5

x = 12
