How many patients had more than 5 cavities?
Answer:
2 patients had more than 5 cavities.
step-by-step explanation:
5 cavities = 26 cavities = 07 cavities = 2Here cavities > 5
so only 2 patients had more than 5 cavities also as had total 7 cavities.
Answer:
2 patients had more than 5 cavities
Step-by-step explanation:
Each dot represents a different patient.
"More than 5" means numbers greater than 5 (so from 6 onwards).
From inspection of the dot plot, there are 2 dots above all the numbers that are greater than 5.
Therefore, there are 2 patients who had more than 5 cavities.
**see annotated dot plot**
The area shaded with a pink rectangle is "more than 5 cavities"

Arcs and angles relay puzzle
Applying the angles of intersecting chords theorem, the value of x in the first figure is: x = 7.
What is the Angles of Intersecting Chords Theorem?If two chords of a circle intersect, the angles of intersecting chords theorem states that, the measure of the angle formed equals 1/2(sum of the measure of the arcs which are intercepted.
Thus, we can use the angles of intersecting chords theorem to find missing angles or value of x in the questions given.
For example, let's find the value of x in the first figure given:
12x + 5 = 1/2(83 + 95)
12x + 5 = 89
12x = 89 - 5
12x = 84
x = 7
Using same strategy, you can solve the rest of the problem given.

c. The number of light bulbs on the Halloween string lights around your window
d. Power in your cell phone battery as you stream a video
Answer:
a. positive
b. negative
c. zero
d. negative
Step-by-step explanation:
You want a description of the sign of the slope of a graph of ...
amount of water in a filling bathtubtemperature of a cooling drinknumber of lights in a stringpower in a battery being usedSlopeThe slope of a graph is the "rise" divided by the "run." Generally, we choose the direction of "run" to be to the right, so the "rise" will be positive when the graph shows an increasing value, and it will be negative when the graph shows a decreasing value. When the rise is zero (the value is neither increasing nor decreasing), the slope is zero.
WaterA graph of the volume of water in a filling tub will show it starts at some low value and increases over time. Generally such a graph will have volume on the vertical axis, and time on the horizontal axis. Since the volume is increasing, the slope is positive.
TemperatureAs a hot drink cools, its temperature decreases. The graph of temperature will generally be drawn with temperature on the vertical axis, and time on the horizontal axis. Since the temperature is decreasing, the slope will be negative.
LightsWe presume there is no process going on that is changing the number of light bulbs in the string of lights, so the value is constant. It is neither increasing nor decreasing, so the slope of its graph will be zero.
PowerIf we presume your cell phone is not connected to a charger while it is streaming video for you, then we can assume the power in the battery is decreasing. The slope of the graph of battery power will be negative.
(If the phone is connected to a charger, the slope may be zero or positive, depending on the power output of the charger. One of my phone chargers is "low power," so the battery power does not increase unless the phone is turned off (not playing video).)

15) The length of OC is twice the length of EO so CE = 1(7) + 2(7) = 3(7)
Answer:
14. B
15. C
Step-by-step explanation:
Question 14
Area of a parallelogram = base × altitude
Given:
area ABEF = 63 cm²base = ABaltitude = 7 cmSubstituting the given values into the formula and solve for AB:
⇒ Area = base × altitude
⇒ 63 = AB × 7
[tex]\sf \implies AB=\dfrac{63}{7}[/tex]

The area of a rectangular piece of metal is 1,984 square centimeters. The perimeter is 188 centimeters. What are the dimensions of the piece?
Answer:
There are 2 options:
x = 32 cm and y = 62 cmx = 62 cm and y = 32 cmStep-by-step explanation:
That's a rectangular piece, therefore let's consider the width to be x and the length to be y.
A = width * length
1) A = x * y = 1,984 cm^2
P = 2 * (width) + 2 * (length)
2) P = 2x + 2y = 188 cm
Isolate x or y in one of the equations.
xy = 1,984 cm^2
y = 1,984 cm^2 / x
Now plug it in the second equation.
2x + 2y = 188 cm
2x + 2 * (1,984 / x) = 188
Now we have only one variable. Now just solve it alegebraically.
2x + (3,968 / x) = 188
Multiply both sides by x in order to get rid of the fraction.
[tex]2x^{2}[/tex] + 3968 = 188 x
Substract both sides by 188 x
2x^2 + 3968 - 188x = 0
Now divide by 2 to make the equation simpler.
x^2 - 94x + 1984 = 0
use the quadratic formula:
[tex]\frac{94 + \sqrt{(-94)^2 - 4(1)(1984)} }{2(1)} = 62\\\frac{94 - \sqrt{(-94)^2 - 4(1)(1984)} }{2(1)} = 32[/tex]
[tex]x1 = \frac{-b + \sqrt{b^2 - 4ac} }{2a} \\x2 = \frac{-b - \sqrt{b^2 - 4ac} }{2a}[/tex]
x is either 62 or 32.
let's find y:
y = 1,984 / x
y = 1,984 / 62 = 32
y = 1,984 / 32 = 62
There are 2 options:
x = 32 cm and y = 62 cmx = 62 cm and y = 32 cm

Nayeli has a points card for a movie theater.
She receives 40 rewards points just for signing up.
• She earns 14.5 points for each visit to the movie theater.
She needs at least 185 points for a free movie ticket.
Answer: She would have to visit the movie theater 10 times.
Step-by-step explanation:
Step-by-step explanation:
I am not sure what the actual question is.
the general function for the amount of gathered reward points p with v visits to the theater is
p(v) = 14.5×v + 40 (40 starting points, 14.5 points per visit)
to know how many visits are needed for a certain amount of points (185) we need to solve that equation for v :
185 = 14.5×v + 40
145 = 14.5×v
v = 145/14.5 = 10
so, she needs at least 10 visits to gather the desired 185 points for a free ticket.
but that applies only to the first free ticket.
after that the function behavior kind of changes, because we have no more starting points :
so to get 2×185 = 370 points for 2 free tickets she will need
370 = 14.5×v + 40
330 = 14.5×v
v = 330/14.5 = 22.75862069...
we need to round up to the next whole number (because there can be no "part-visits").
so, she will need 23 visits for 2 free tickets (that means 13 more visits for the second free ticket).

Answer:

Step-by-step explanation:
Domain:
0≤x≤17
Range:
0≤y≤12
Step-by-step explanation:
I guess your problem is understanding what is domain and range.
well, the domain is the interval or set of valid values for x for a function or curve.
the range is the interval or set of valid values for y (or function results) for a function or curve.
our function or curve here is the graph of a throw of a basketball.
that throw went continuously from 0 ft to 17 ft distance from the player.
and the height of the ball went continuously from 6 ft to 12 ft and then all the way down to 0 ft (on the floor).
as the graph shows : distance (or horizontal displacement) is our "x".
and the height is our "y".
so, the domain is
0 <= x <= 17
and the range is
0 <= y <= 12
and the code is then
0 17 0 12

Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
O y-2 = 3(x +1/2)
O y-3 = 2(x + 1/2)
O y+ 1/2 = 3(x - 2)
o y + 1/2 = 2(x - 3)
Answer:
[tex]\displaystyle y + \frac{1}{2} = 3\, (x - 2)[/tex].
Step-by-step explanation:
Consider a line in a cartesian plane that goes through the point [tex](x_{0},\, y_{0})[/tex]. If the slope of this line is [tex]m[/tex] (a real constant,) the equation of this line in point-slope form would be:
[tex]y - y_{0} = m\, (x - x_{0})[/tex].
The line in this question goes through the point [tex](2,\, (-1/2))[/tex]. Thus, [tex]x_{0} = 2[/tex] whereas [tex]y = (-1/2)[/tex]. The slope of this line is [tex]m = 3[/tex]. Thus, the equation of this line in point-slope form would be:
[tex]y - (-1/2) = 3\, (x - 2)[/tex].
Simplify to obtain:
[tex]y + (1/2) = 3\, (x - 2)[/tex].
