Step-by-step explanation:
the area of a square is 225cm². On the map drawn to scale 1 : 3 find the area of the square
Answer:
25 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Area if a square = length²
225 = length²
length = √225
length = 15
if the map is drawn to scale of 1 : 3
the length on the map = 15/3 = 5
area of the square 5 x 5 = 25

(50 points) Write an equation for the sine waves.
Answer:
It started from the Origin(Sine graph). It curved upwards immediately it started... Meaning graph's amplitude is gonna be positive one
The Equation for a sine graph is ASin[B(x-C)] + D
A=Amplitude
B= 2π/period
C= c value at the starting point.
D= y value at starting point
Let your Starting point be at the sinusoidal axis (Max + Min)/2.
Looking at this graph
Let's take 1cm on the y axis to be 1unit(1,2,3,4...)
On the x axis... let's take 1cm to be π units(π,2π,3π....)
To get the sinusoidal axis Max - Min/2
Since 1cm is 1unit
Max =1 (from the graph)
Min= -1
1-1/2 = 0
The axis is at the center of middle
Meaning
D=y=0(Its directly at the x axis)
From this axis at the origin... The graph goes... Intercept Maximum... intercept Minimum... Meaning its a Positive sine graph.
A=amplitude = 1cm
B=Period...(Time to complete one Oscillation)
It doesn't fall directly on an x value... It falls at the 1.9th position. or 19/10
B=2π/Period.
B=2π/19/10
B=2π x 10/19
B=20π/19
C=0
Writing the Equation
Y= 1Sin[20π/19(x-0)] +0
ie
Y = Sin [20πx/19]
My thoughts on it
Correct me if wrong... Thanks
Find the value of x such that the data set has the given mean.
Answer:
39.1
Step-by-step explanation:
31.7 + 42.8 + 26.4 = 100.9
35 times 4 = 140
140 - 100.9 = 39.1
Answer:
[tex]mean = \frac{31.7+42.8+26.4+x}{4} \\\\35 = \frac{31.7+42.8+26.4+x}{4} \\\\\\35*4 = 31.7+42.8+26.4+x \\\\140 = 100.9 + x\\\\x= 39.1[/tex]

Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light
is still good but she can be close to the sea life during her scuba dive. Which two equations can be used to find the
minimum and maximum depths Laurie wants to stay between?
-30 - x = 10 and -30 - x = -10
• -30 + x = 10 and -30 + x = -10
O x + 10 = 30 and x + 10 = -30
O x - 10 = 30 and x - 10 = -3
Answer:
[tex] \boxed{-30\:– \: x \:= \: 10 \: \: and \: -30 - x = -10} [/tex]
The equations can be used to find the minimum and maximum depths are (a) [tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]
The current diving depth (d) is given as:
[tex]d = -30ft[/tex]
The position (p) she tries to stay is given as:
[tex]p = 10ft[/tex]
Represent the minimum and the maximum distances with x.
So, the distances are calculated using:
[tex]d - x = p[/tex] and [tex]d - x = -p[/tex]
Substitute values for d and p
[tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]
Hence, the equations can be used to find the minimum and maximum depths are (a) [tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]

Find the measure of x and y.
Answer:
x = 24°, y = 53°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc.
arc EC = 2 × ∠ EDC = 2 × 78° = 156°
x = arc BE = 180° - arc EC = 180° - 156° = 24°
------------------------------------------------------------------
arc CD = 2 × CED = 2 × 41° = 82°
arc BD = 180° - arc CD = 180° - 82° = 98° , then
∠ BCD = [tex]\frac{1}{2}[/tex] × 98° = 49°
Then
y + 78° + 49° = 180° (sum of angles in triangle )
y + 127° = 180° ( subtract 127° from both sides )
y = 53°

A national health organization warns that alcohol use among middle school students is on the rise. Concerned, a local health agency randomly and anonymously surveys 110 of the middle school students in its city. 21 of them report having been intoxicated. Create a 90% confidence interval. Find p-hat. (p -hat = x/n)
Answer:
CI 90 % = [ 0,05 ; 0,16 ]
Step-by-step explanation:
From sample we got
n = 110
x = 21
p = 21/110 = 0.19 then q = 1 - p q = 1 - 0.19 q = 0.81
To create a 90 % confidence Interval, the significance level α = 10 %
α = 0.1 α/2 = 0.05
t(c) for α/2 = 0.05 is from z-table z(c) = 1.64
CI 90 % = ( p ± z(c) * √(p*q)/n
CI 90 % = [ 0,11 ± 1.64 * √ (0.19*0.81)/110 ]
CI 90 % = [ 0.11 ± 1.64 * 0.037 ]
CI 90 % = [ 0.11 ± 0,06 ]
CI 90 % = [ 0,05 ; 0,16 ]

Dayquan decided to run some laps around the track. If the diameter of the track is 75 feet, how far around the track did he run?
Answer: 235.5 feet
Step-by-step explanation:
In this case, we have to calculate the circumference of the track. The circumference will be calculated as:
= 2πr
Diameter = 75 feet.
Radius = 75/2 = 37.5 feet
Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet

Carmen wants to join a gym. Gym A costs $26.76 plus an additional $4 for each visit. Gym B has no initial fee but costs $12.92 for each visit. After how many visits will both plans cost the same?
Answer:
After 3 visits both plans will cost the same.
Step-by-step explanation:
Gym A costs $26.76 plus an additional $4 for each visit.
Gym B has no initial fee but costs $12.92 for each visist.
The cost for gym A can be written as
C= $26.76 + 4(x) where x is the number of visits to the gym A
The cost for gym B can be written as
C= $12.92 (x) where x is the number of visits to the gym B
Both costs will be equal
12.92x= 26.76 +4x
12.92x-4x= 26.76
8.92x= 26.76
x= 26.76/8.92
x= 3
after 3 visits both plans will cost the same.
Check
12.92x= 26.76 +4x
12.92*3= 26.76 +12

The scatterplot below represents the number of hot drinks sold on a given
day versus the low temperature of that day. Of the following lines, which
best fits the data in the scatterplot?
Answer:
A) y=-1/2x+55
Step-by-step explanation:
We can clearly see a negative trend/association between the number of hot drinks sold on a given day and the low temperature of that day. Therefore, the slope of the best line of fit must be negative, eliminating D and E. Also, notice that when the low temperature is 0°F, the number of hot drinks sold is about 55, which is a good indicator of our y-intercept or constant, eliminating choice C. Because the best line of fit is not so steep, the slope will be closer to 0 if it's a negative trend. This eliminates choice B, making the correct answer A.

(2,0) -> (6, -2) requires a transition of (+4, -2) now we divide the new number by 2 to find the amount changed from each side (+2,-1) then we add that to the original point (2,0) to get (4,-1)
Quadrilateral WXYZ has vertices at the points W(-3,2), X(-1,3), Y(0,1), and Z(1,0). Find the slope of side xy.
Answer:
The slope of the side xy is -2
Step-by-step explanation:
To find the slope of the side xy, we use the slope formula
we have the formula as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-1,3)
(x2,y2) = (0,1)
m = (1-3)/(0 + 1) = -2/1 = -2
