Answer:

57

Step-by-step explanation:

Given that :

Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds

Margin of Error, E = 78

Assume a confidence interval of 95%;

Using the relation :

((Zα/2 * σ) / E)²

(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025

Z0.025 = 1.96

Sample size = ((1.96 * 300) / 78)²

Sample size = (588 / 78)^2

Sample size = 7.5384615^2

Sample size = 56.828

= 57 samples

Answer:

SAS

Step-by-step explanation:

It's the only answer that can satisfy with the figures

By B. SAS (side, angle, side) congruency theorem shows the two triangles are congruent

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

The congruency theorem should always be consecutive angles or sides to the corresponding consecutive angles or sides.

Side PR and VS are congruent also m∠R and m∠V is similar and the sides VT and QR is also congruent.

Therefore, The congruency theorem that holds this is SAS.

Given:

M=-5 and (-3,-2).

To find:

The equation in the form [tex]y=mx+b[/tex].

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]          ...(i)

where, m is slope and b is y-intercept.

We have m=-5. Putting m=-5 in (i), we get

[tex]y=-5x+b[/tex]          ...(ii)

We have a point (-3,-2). Putting x=-3 and y=-2 in (ii), we get

[tex]-2=-5(-3)+b[/tex]

[tex]-2=15+b[/tex]

[tex]-2-15=b[/tex]

[tex]-17=b[/tex]

So, the value of b is -17.

Putting b=-17 in (ii), we get

[tex]y=-5x+(-17)[/tex]

[tex]y=-5x-17[/tex]

Therefore, the required equation is [tex]y=-5x-17[/tex].

Given:

The graph of a function [tex]y=h(x)[/tex].

To find:

The interval where [tex]h(x)>0[/tex].

Solution:

From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, [tex]h(x)>0[/tex] for [tex]x<0[/tex] and [tex]x>3.6[/tex].

The function between x=0 and x=3.6 lies below the x-axis. So, [tex]h(x)<0[/tex] for [tex]0<x<3.6[/tex].

Now,

For [tex]-1<x<0[/tex], the graph of h(x) is above the x-axis. So, [tex]h(x)>0[/tex].

For [tex]0<x<1[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].

For [tex]1<x<2[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].

Only for the interval [tex]-1<x<0[/tex], we get [tex]h(x)>0[/tex].

Therefore, the correct option is A.

Answer:

464

Step-by-step explanation:

Find other angle:

<B = 180 - 165 - 11 = 4

Then plug in (opposite sides go together):

[tex]\frac{a}{sin 11}[/tex] = [tex]\frac{630}{sin 165}[/tex]

[tex]a = \frac{630 sin 11}{sin 165} = 464.454 = 464[/tex]

The length of side a in ΔABC is 460 inches.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sine rule of ΔABC which is a/sinA = b/sinB = c/sinC.

Given, In ΔABC, c = 630 inches, ∠C=165° and ∠A=11°.

∴ a/sinA = c/sinC.

a/sin11° = c/sin165°.

a/0.19 = 630/0.26.

a = (630×0.19)/0.26.

a = 460.
