Answers

Answer:

4th option

Step-by-step explanation:

[tex]\frac{n}{360}[/tex] represents the fraction of the circle occupied by the sector , that is

The ratio of degrees in the sector's central angle to the total number of degrees in the circle

Option 4 is correct. The ratio of degrees in the sector's central angle to the total number of degrees in the circle.

What is the fraction?

Fraction is defined as the number of composition constitute the Whole.


area of a sector is a secotor = n/360 degrees pie r^2
n =number of fraction at which the circle is divided
mean n = in degrees x number of angles.
and the ratio n/360 degrees
describes the number of partition to the circle.

Thus, the ratio n/360 degrees defines The ratio of degrees in the sector's central angle to the total number of degrees in the circle.

The theater sells two types of tickets: adult tickets for $11 and child tickets for $9.

Last night the theater sold 262 tickets for a total of $2482. How many adult tickets did the theater sell last night?

Answers

Answer:

a=62

Step-by-step explanation:

11a + 9c=2482 equation 1

a + c = 262 equation 2

a=262-c isolate value of a in equation

11(262-c) + 9c = 2482 substitute value of a (262-c) into equation 2

2882-11c + 9c= 2482 solve

-2c=-400

c=200

a+c=262

a+200=262

a=62

Check answer:

11a + 9c=2482

11(62)+9(200)=2482

682+1800=2482

2482=2482

Answer:

See the proof below

Step-by-step explanation:

prove that 1-cosA/sinA=cosecA-cotA​

Starting from RHS

cosecA-cotA​

From trig identty

cosec theta = 1/sintheta and cot theta = cos theta/sin theta

Hence;

cosecA-cotA​

= 1/sinA - cosA/sinA

GIVEN :-

Slope of the line = 1y-intercept of the line = -5

TO FIND :-

Equation of the line in slope-intercept form

FACTS TO KNOW BEFORE SOLVING :-

Lets say there's a line whose slope is 'm' & y-intercept is 'c'. So, the equation of line in slope-intercept form is → [tex]\boxed {y = mx + c}[/tex]

41. How would the graph of the function
y=x2- 3 be affected if the function were
changed to y=x2 + 2?
A. The graph would shift 2 units up.
B. The graph would shift 5 units up.
C. The graph would shift 5 units down.
D. The graph would shift 1 unit up,

Answers

Answer:

B. The graph would shift 5 units up.

Step-by-step explanation:

Before the change:

Before the change, the function was given by:

[tex]y = x^2 - 3[/tex]

After the change:

After the change, the function was given by:

[tex]y = x^2 + 2[/tex]

Considering the function as it was before the change, it can also be written as:

[tex]y = x^2 - 3 + 5[/tex]

Which means that 5 was added to the function, and when a number n is added to a function, there function is shifted n units up. So the correct answer to this problem is given by option B.

A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities.

City n x s

B 32 $5.15 $0.85

Assume that the population variances of both groups are different. Test if there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different. Conduct the hypothesis testing (optional) in paper.

Answers

Answer:

We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Step-by-step explanation:

Given :

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

H0 : μ1 - μ2 = 0

H0 : μ1 - μ2 ≠ 0

n1 = 26 ; x1 = 4.05 ; s1 = 0.55

n2 = 32 ; x2 = 5.15 ; s2 = 0.85

Tstatistic :

(x1 - x2) / √(s1²/n1 + s2²/n2)

(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)

-1.1 / 0.1849668

= - 5.947

Using the smaller n;

df = n - 1 ; 26 - 1 = 25

Pvalue = (-5.947, 24)

Pvalue = 0.000001

Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Answer:

y = x + 3

Step-by-step explanation:

Equation of the line can be written as y = mx + b (slope-intercept form)

Let's find the slope (m) and the y-intercept (b)

Slope (m) = change in y/change in x

Using two points on the line, (0, 3) and (1, 4),

Slope (m) = (4 - 3)/(1 - 0) = 1/1

m = 1

y-intercept (b) = 3 (the coordinate of the point where the y-axis is intercepted by ye line)

To write the equation, substitute m = 1 and b = 3 into y = mx + b

y = 1(x) + 3

y = x + 3
