Step-by-step explanation:
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.

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.

Answer:1/56
Step-by-step explanation:1. 8P8 = 8!/(8-8)!=8!/0!=8
2. 6P6 = 6!/(6- 6)! = 6!/0!=6
3.6/8=7.8=1/56
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.

Step-by-step explanation: Because the angle PQS is not a 90 degree angle it should equal 180 degrees, it is now lowered down to the answers A. and B. Answer B. has 2x and answer A. has just x. if it were to be 2x then the x would have to represent 30 degrees but the point plotted x does not equal 30 degrees therefore leaving the last answer as A. x-60=180
The table shows the approximate area in square miles of the largest and smallest states in the United States.
State Area (mi2)
Alaska 873
Rhode Island 392
What is the difference between the areas in square miles?
__ square miles
The difference between the areas in square miles is 481.
Given that Alaska is 873 sq miles in size, while Rhode Island is 392 sq miles in total, to determine what is the difference between the areas in square miles, the following calculation must be performed:
873 - 392 = X 481 = X

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

i tried working it out and got 21 but the answer was 26 , how do you show your workings
Answer:
26
Step-by-step explanation:
3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )
3x-9 = 5x-4 + 21 - 3x
collect like terms
3x-9 = 2x +17
move the terms
3x-2x = 17+9
x=26
Answer:
26
Step-by-step explanation:
3 (x-3) = 5x - 4 + 3 (7-x)
3x - 9 = 5x - 4 + 21 - 3x
3x - 9 = 5x - 3x + 17
3x - 9 = 2x + 17
3x - 2x = 17 + 9
x = 26

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

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)
angle 9 =angle 6 = 45 degrees (corresponding angles)
angle 5=angle 9=45 degrees (vertical angles)
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

The slope of the line y=3x is 3
Answer:
TRUE
Step-by-step explanation:
I HOPE IT'S HELP .............
What is the slope of the line on the graph?
Answer:
5
Step-by-step explanation:
the slope is the change in y divided by the change in x
as y goes up 5 x goes up 1
5/1=5 so the slope is 5
Answer:
6
Step-by-step explanation:
To find the slope you use rise over run.
Count how far each of the dots are from each other and you should get 6. That is your rise. See how far it goes to the right or left and you should get 1, which is your run.
Since it is rise over run, it would be 6/1, which makes your answer 6

The GCF of 14 and 4 is 2
Divide both terms by the GCF, 2:
14 ÷ 2 = 7
4 ÷ 2 = 2
The ratio 14 : 4 can be reduced to lowest terms by dividing both terms by the GCF = 2 :
14 : 4 = 7 : 2
Therefore:
