In ΔSTU, the measure of ∠U=90°, UT = 12, SU = 35, and TS = 37. What ratio represents the secant of ∠T?

Answer:

a) CI ( 99% )  = ( 145,45 : 162,55)

b) b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI  let´s say to 95 % but in that case

you will increase de error type I

Step-by-step explanation:

a) CI = 99 %       α = 1%   α = 0,01

From z-table     z(c)  ≈ - 2,325    |z(c)| ≈ 2,325

CI = ( μ₀ ± z(c) * σ/√n )

CI = ( 154 - (2,325) * 26/√50 ; 154 + (2,325) * 26/√50 )

CI = ( 154 -  8,55  ;  154 + 8,55

CI ( 99% )  = ( 145,45 : 162,55)

b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI  let´s say to 95 % but in that case

you will increase de error type I

30 x 30 = 900

This is the surface area of one side

900 x 6

Multiply by 6 to get the surface area of all 6 sides of the cube

900 x 6 = 5400

Answer:

Simplifying

an = 8n + -7

Reorder the terms:

an = -7 + 8n

Solving

an = -7 + 8n

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Divide each side by 'n'.

a = -7n-1 + 8

Simplifying

a = -7n-1 + 8

Reorder the terms:

a = 8 + -7n-1

Answer:

The answer is x < 4

Step-by-step explanation:

1) Subtract 6 from both sides.

[tex]4x < 22 - 6[/tex]

2) Simplify 22 - 6 to 16.

[tex]4x < 16[/tex]

3) Divide both sides by 4.

[tex]x < \frac{16}{4} [/tex]

4) Simplify 16/4 to 4.

[tex]x < 4[/tex]

Therefor, the answer is x < 4.

Delta math

Answer: B. (2,1)

Step-by-step explanation:

its not c because if you look at R you see that it is going 4,3 not 3,4 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then the x-axis.

It's not D because if you look at Q you see that it is going 3,5 not 5,3 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then x-axis.

That's the same thing for A so your answer is b.

Answer:

21

Step-by-step explanation:

I haven't done this in a long time but this is what I know: the discount would overall be 25%. So, you set it up by .25(84) = 21. Therefore the jacket would cost $21.

Answer:

total surface area (TSA) = [tex]2bs[/tex] + [tex]b^{2}[/tex]

                      length      = 6 mi

                    slant height = 7 mi

           ∴ TSA                   = 2 × 6 × 7 + [tex]6^{2}[/tex]

                                       = 84 + 36

                                      = 120

The surface area of the square pyramid is 120 sq. mi.

Given:

side length (s) = 6 mi

slant height (l) = 7 mi

*image of a typical square pyramid is shown in the attachment below.

Recall:

Formula for surface area of square pyramid (SA) = [tex]A + \frac{1}{2} Pl[/tex]

Where,

[tex]A =[/tex] area of the base = [tex]s^2 = 6^2 = 36[/tex] sq mi

[tex]P =[/tex] perimeter of the base = [tex]4(s) = 4\times 6 = 24[/tex] mi

[tex]l =[/tex] slant height = 7 mi

Plug in the values

[tex]SA = 36 + \frac{1}{2}\times 24\times 7\\SA = 36 +84\\SA = 120[/tex]

The surface area(SA) of the square pyramid is 120 sq. mi

The reference angles are in the first, second, third, and fourth is 78°, 102°, 258°, and 282° respectively.

the angle between the terminal side of the angle and the x-axis.

For the first quadrant:

The reference angle = 258 - 180 = 78°

For the second quadrant:

= 180 - 78 = 102°

For the third quadrant:

= 78 + 180

= 258°

For the fourth quadrant:

= 360- 78

= 282°

Thus, the reference angles are in the first, second, third, and fourth is 78°, 102°, 258°, and 282° respectively.

Answer:

B, [tex]8\sqrt{2}[/tex]

Step-by-step explanation:

Diagonals of a square are congruent so AC= 4

using pythagorean theorem we can then do [tex]x^{2} +x^{2}[/tex]=[tex]4^{2}[/tex]

[tex]2x^{2} = 16\\x^{2} =8\\x=\sqrt{8} \\x=2\sqrt{2}[/tex]

Then for perimeter we times the [tex]2\sqrt{2}[/tex] by 4 and get
