Step-by-step explanation:
Two percent of the customers of a store buy cigars. Half of the customers who buy cigars buy beer. 25 percent who buy beer buy cigars. Determine the probability that a customer neither buys beer nor buys cigars.
Answer:
0.95
Step-by-step explanation:
The computation of the probability that a customer neither buys beer nor buys cigars is given below;
Given that, the probabilities are
The customers who purchased cigars be 0.02
The customers who purchased cigars + beer 0.50
And, the customers who purchased beer + cigars be 0.25
Now the probabilities where the customer purchased both
= 0.05 × 0.02
= 0.10
The probability where the customer purchased beer is
= 0.01 ÷ 0.25
= 0.04
Now the probability where a customer neither buys beer nor buys cigars is
= 1 - 0.02 + 0.04 - 0.01
= 0.95
Diamond wants to buy her god son some toys that will fill his new toy chest that is 3 feet by 2 feet. She knows that it will take 320 toys to fill 1 foot squared. How much would she spend on toys at Target to fill the chest. Use the formula A=L×W
Answer:
1920 toys
Step-by-step explanation:
Area of new toy chest :
Area = Length * width
Area = 3 feets * 2 feets
Area of new toy chest = 6 ft²
If ;
1 square foot requires 320 toys
6 ft² = (320 * 6) = 1920 toys
Which graph shows the system 1 x++y=2 ? [x2 + y2 =9
Answer:
The graph of the system in the attached figure
Step-by-step explanation:
we have
isolate the variable y
----> equation A
This is the equation of a vertical parabola open down (because the leading coefficient is negative)
The vertex represent a maximum
the vertex is the point (0,2)
---> equation B
This is the equation of a circle centered at (0,0) with radius 3 units
The solution of the system of equations is the intersection points both graphs
using a graphing tool
The solutions are the points (-2.05,-2.19) and (2.05,-2.19)
see the attached figure
Answer:
It's C!

the sum of x and five is the product of 3 and x increased by 13
Answer:
x = -4
Step-by-step explanation:
[tex]x + 5 = 3x + 13[/tex]
Subtract [tex]3x[/tex] from both sides of the equation. You get:
[tex]-2x + 5 = 13[/tex]
Subtract 5 from both sides:
[tex]-2x = 8[/tex]
[tex]x = -4[/tex]

-7.4r - 6.31 = 3.23 - 5.6r
Answer:
r=−5.3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7.4r−6.31=3.23−5.6r
−7.4r+−6.31=3.23+−5.6r
−7.4r−6.31=−5.6r+3.23
Step 2: Add 5.6r to both sides.
−7.4r−6.31+5.6r=−5.6r+3.23+5.6r
−1.8r−6.31=3.23
Step 3: Add 6.31 to both sides.
−1.8r−6.31+6.31=3.23+6.31
−1.8r=9.54
Step 4: Divide both sides by -1.8.
−1.8r/−1.8=9.54/−1.8
r=−5.3

An electrician charges $40 to come to your house . She also charges $55 for each hour that she works .The electrican changes you a total of $190.How many hours does the electrican work at your house
Can you please tell me what yo write on my tape diagram
Answer:
about 2.72 hours
Step-by-step explanation:
set up the equation:
40 + 55h = 190
subtract 40 from both sides
55h = 150
now divide both sides by 55
h = 2.72
80% of p is 20. What is p? 75% of b is 12. What is b?
Step-by-step explanation:
80% of p = 20
=> 0.8p = 20, p = 20 / 0.8 = 25.
75% of b = 12
=> 0.75b = 12, b = 12 / 0.75 = 16.
Answer:
[tex]80\% \: of \: p = 20 \\ \frac{80}{100} p = 20 \\ \frac{4}{5} p = 20 \\ p = \frac{20 \times 5}{4} \\ \boxed{p = 25}[/tex]
25 is the right answer.[tex]75\% \: of \: b = 12 \\ \frac{75}{100} b = 12 \\ \frac{3}{4} b = 12 \\ b = \frac{12 \times 4}{3} \\ \boxed{b = 16}[/tex]
16 is the right answer.Can someone help me out with this?
i Think all are correct not sure tho
Answer:
See below.
Step-by-step explanation:
Note: I am considering that you are supposed to think of the graph maximum point as P(x, y) = P(0, 25).
It means that the absolute maximum at x = 0, so f(0) = 25.
What is the maximum of this graph and what does it represent?
When the ball is on the ground? No, once the maximum of this graph is 25 feet and the ground is 0 feet, the statement is false.
Where the ball ended? No, the final position is h = 0 feet, not h = 25 feet.
Where the ball started? Yes, the ball was dropped in h = 25 feet.
It represents the highest point on the graph? Yes.
25 feet? Yes.
True or False: 4×4×4+5×5 = 43 + 52
Answer:
False
Step-by-step explanation:
4x4=16

Therefore the answer is false, because 89 is not equal to 95.
Answer:
false
Step-by-step explanation: you don't really need this part but all you need to know is that it is false :)

The design plans for a new concert hall show elevations relative to ground level at 0 feet. The elevation of the balcony floor is 37 feet, and the elevation of the basement floor is -17 feet. How many feet above ground level is the balcony floor?
Answer: The bacony floor is 37 feet above the ground floor.
Step-by-step explanation:
Here, the ground level is marked as 0 feet.
The elevation of the balcony floor is 37 feet.
The elevation of the basement floor is -17 feet.
Since elevations relative to ground level at 0 feet.
i.e. elevation of balcony floor is same as the distance of balcony floor from ground.
That means the bacony floor is 37 feet above the ground floor.
Hence, the bacony floor is 37 feet above the ground floor.
