At a certain pizzeria, it is known that 12% of orders are for extra-large pizzas. What is the probability that the 6th pizza ordered is the first extra-large pizza? 0.0633 0.4644 0.5277 0.9367
[tex]0.0633[/tex] is the the probability that the 6th pizza ordered is the first extra-large pizza.
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
According to question, at a certain pizzeria, it is known that 12% of orders are for extra-large pizzas.
We have to find, what is the probability that the 6th pizza ordered is the first extra-large pizza.
Probability of extra-large pizzas [tex]=\frac{12}{100}[/tex][tex]=0.12[/tex]
Probability of other pizzas[tex]=1-0.12=0.88[/tex]
Hence, the probability that the 6th pizza ordered is the first extra-large pizza[tex]=0.88^{5}[/tex]×[tex]0.12[/tex](since first 5 pizzas are other pizza)
[tex]=0.527[/tex]×[tex]0.12[/tex]
[tex]=0.0633[/tex]
Hence, we can conclude that [tex]0.0633[/tex] is the probability that the 6th pizza ordered is the first extra-large pizza.

Answer:
0 i think if im wrong im sorry
Step-by-step explanation:
Answer:
The answer is x=6, y=3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite(−1)⋅(4x−7y)=(−1)(3)x−7y=−15
Simplify.
−4x+7y=−3x−7y=−15
Add the two equations together to eliminate y from the system.−4x+7y=−3+x−7y=−15−3x=−18
Divide each term by −3 and simplify.
x = 6
Substitute the value found for x into one of the original equations, then solve for y.
y = 3
The solution to the independent system of equations can be represented as a point.(6,3)
The result can be shown in multiple forms.

Find the percent rate of change for each
function and tell whether it shows
exponential growth or decay.
a) y = 110(.95)
b) y = 1.08(1.07)
plz help!!
Answer:
Step-by-step explanation:
a) f(t) = 110(0.95)^t
0.95<1, so the function shows 5% decay
b) f(t) = 1.08(1.07)^t
1.07 > 1, so the function shows 7% growth

Solution:
Answer:
150120.83 ; 40 ; 1800
Step-by-step explanation:
Amount of share per person = x
Number of persons = y
x = k/y
k = constant of proportionality
k = xy
257,350 * 7 = 1801450
k = 1801450
If there are 12 persons ; y = 12
x = k/y
x = 1801450 / 12
x = 150120.83
2.) weight on Mars = m
Weight in earth = e
m α e
m = ke
48 = 120k
k = 48 / 120
k = 0.4
m = 0.4 * 100
m = 40
3.)
I α pt
I = kpt
600 = k * 10000 * 2
600 = 20000k
k = 600/20000
k = 0.03
I = 0.03 * 15000 * 4
I = 1800

Two angles are supplementary. The measure of one angle is 5 greater than 40% of the other. Find the measures of both angles.
Answer:
Step-by-step explanation:
0.40beta%2Bbeta=180-5
1.40beta=175
beta=175%2F1.40
highlight%28beta=125%29�
then alpha%2B125=180 =>alpha=180-125 =>highlight%28alpha=55%29
The required values of angles are 125 and 55.
What is angle ?When two straight lines come together at a point, they produce an angle, which is represented by the symbol.
Given that,
Two angles are supplementary to each other.
Let angles are α and β.
According to given condition,
α + β = 180 (1)
Also, the measure of one angle α is 5 greater than 40% of the other.
α = 0.4 β + 5 (2)
Substitute the value of α in equation (1),
0.4 β + 5 + β = 180
1.4 β = 175
β = 175 / 1.4 = 125
The value of α =0.4 x 125 + 5 = 50 + 5 = 55
The value of angle α and β are 125 and 55.

Step-by-step explanation:
The graphs of square root functions are always curved.
HOW DO YOU FIND ANGLE 1
Answer:
If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.
Step-by-step explanation:
a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

Given that lines q and m are parallel and are cut by two
different transversal lines, j and k, use angle relationships
to determine the measure of each numbered angle:
angle 1 = 180-110 = 70 degrees (linnear pair)
angle 2= 180-115 = 65 degrees (linnear pair)
angle 3 = angle 2 = 65 degrees (corresponding angles)
angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)
(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)
angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees
angle 6 = angle 7 = 45 degrees ( vertical angles)
angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)

Step-by-step explanation:
3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )
3x-9 = 5x-4 + 21 - 3x
collect like terms

Step-by-step explanation:
3 (x-3) = 5x - 4 + 3 (7-x)
3x - 9 = 5x - 4 + 21 - 3x
3x - 9 = 5x - 3x + 17

A plumber has 150m of pipes.The plumber uses 20% fitting a central heating system,and then 25% of what is left to fit a bathroom. How much pipe does the plumber use to fit the bathroom?
Answer:
30 m
Step-by-step explanation:
Total length of pipe = 150 m
Central heating system = 20% of 150 m
= 0.2 × 150
= 30 m
Length of pipe remaining = 150 m - 30 m
= 120 m
Bathroom fitting = 25% of 120 m
= 0.25 × 120
= 30 m
The plumber used 30 m of pipe to fit the bathroom

If , then what is mto the nearest degree?
Given:
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
To find:
The measure of angle A to the nearest degree.
Solution:
We have,
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
It can be written as
[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]
[tex]\angle A=70.00123^\circ[/tex]
[tex]\angle A=70^\circ[/tex]
Therefore, the measure of angle A to the nearest degree is 70 degrees.
