A tourist in Ireland wants to visit five different cities. If the route is
randomly selected, what is the probability that the tourist will visit the
cities in alphabetical order? Round your answer to three decimal places.
0.004
1.234
0.023
0.008
Answer:
0.008
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Total outcomes:
He will visit 5 different cities. So the total number of ways this can happen is an arrangment of 5 elements, that is:
[tex]T = A_{5} = 5! = 120[/tex]
Desired outcome:
In alphabetical order, so only one possible outcome, which means that [tex]D = 1[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.008[/tex
1.160 is what percentage of 40? 2.40 is 160% of what number? 3. What number is 40% of 160?
Answer:
1) 400
2) 25
3) 64
Step-by-step explanation:
Answer:
1. 400%
2. 25
3. 64
Step-by-step explanation:
1. 160 ÷ 40 = 4.00 then move the decimal over two places to the right to get 400 ----> 400%
2. 40 ÷ 160 = 0.25 move the decimal over two places to the left and you get 25
3. 160 ÷ 10 = 16 (10%) 16 x 4= 64 (10% x 4 = 40%)

A can manufacturing company is designing a can of cat food to hold 5.5 oz or about 163 cm(3). They have written out that the equation for the surface area for a can with the volume is S=2pie radius(2) + 163/r. Explain why the equation is wrong and how to fix it.
Answer:
The correct equation that describes the surface area is [tex]A_{s} = 2\pi \cdot r^{2}+\frac{326}{r}[/tex] and we need to multiply [tex]\frac{163}{r}[/tex] by 2 in the equation described in the statement to correct the equation.
Step-by-step explanation:
Let suppose that the can of cat food is a right cylinder. The surface area of the cylinder ([tex]A_{s}[/tex]), measured in square centimeters, is the sum of the areas of the circular walls ([tex]A_{cw}[/tex]) and the non-circular wall ([tex]A_{ncw}[/tex]), both measured in square centimeters. That is:
[tex]A_{s} = 2\cdot A_{cw}+A_{ncw}[/tex] (1)
By Geometry, we expanded the equation above:
[tex]A_{s} = 2\pi\cdot r^{2}+2\pi\cdot r\cdot h[/tex] (1b)
Where:
[tex]r[/tex] - Radius, measured in centimeters.
[tex]h[/tex] - Height, measured in centimeters.
And the volume of the right cylinder ([tex]V[/tex]), measured in cubic cnetimeters, is defined by the following formula:
[tex]V = \pi\cdot r^{2}\cdot h[/tex]
Then, we clear the height of the cylinder within the volume formula:
[tex]h = \frac{V}{\pi\cdot r^{2}}[/tex] (2)
By substituting in (1b), we obtain the following equation:
[tex]A_{s} = 2\pi \cdot r^{2} + 2\pi\cdot r\cdot \left(\frac{V}{\pi\cdot r^{2}} \right)[/tex]
[tex]A_{s} = 2\pi\cdot r^{2}+\frac{2\cdot V}{r}[/tex] (1c)
If we know that [tex]V = 163\,cm^{3}[/tex], then the equation for the surface area of the cylinder is:
[tex]A_{s} = 2\pi \cdot r^{2}+\frac{326}{r}[/tex]
In a nutshell, we need to multiply [tex]\frac{163}{r}[/tex] by 2 to correct the equation.
Donte scored 55 on his mastery exam. What percent did Donte score?
Answer: See explanation
Step-by-step explanation:
Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.
Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:
= 55/80 × 100
= 68.75%
PLEASE HELP I KEEP GETTING THIS WRONG
Answer:
Given function:
y = -7x - 1This is a linear function. To graph this you need to plot two different points and connect them with a line.
Examples of the points:
x = 0, theny = -7*0 - 1 = -1and
x = 1, theny = -7*1 - 1 = -8So the points are:
(0, -1) and (1, -8)See attached graph
Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Consider the function,
f(1) = 21 - 6
Match each transformation of Rx) with its description.
g() = 21 – 10
9(0) = 21 - 14
g(1) = 81 - 4
g(t) = 21 - 2
g(1) = 81 - 24
g(I) = 85 - 6
shifts 1x) 4 units right
stretches x) by a factor
of 4 away from the x-axis
compresses (x) by a factor
of 4 toward the y-axis
shifts x 4 units down
Answer:
Shift 4 units down: [tex]g(x) = 2x - 10[/tex]
Stretching f(x) by 4 : [tex]g(x) =8x - 24[/tex]
Shift 4 units left: [tex]g(x) = 2x - 14[/tex]
Compress by 1/4 units : [tex]g(x) = 8x - 6[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x - 6[/tex]
Required
Match the transformations (See attachment)
Shift 4 units down
Shifting down a function is represented as:
[tex]g(x) = f(x) - b[/tex]
In this case:
[tex]b = 4[/tex]
Substitute expression for f(x) and 4 for b in [tex]g(x) = f(x) - b[/tex]
[tex]g(x) = 2x - 6 - 4[/tex]
[tex]g(x) = 2x - 10[/tex]
Stretching f(x) by 4
Stretching a function by some units is represented as:
[tex]g(x) =b.f(x)[/tex]
In this case:
[tex]b = 4[/tex]
Substitute expression for f(x) and 4 for b in [tex]g(x) =b.f(x)[/tex]
[tex]g(x) =4 * (2x - 6)[/tex]
[tex]g(x) =8x - 24[/tex]
Shift 4 units left
Shifting a function to the left is represented as:
[tex]g(x) = f(x - b)[/tex]
In this case:
[tex]b = 4[/tex]
Substitute expression for f(x) and 4 for b in [tex]g(x) = f(x - b)[/tex]
[tex]g(x) = f(x-4)[/tex]
Calculating f(x - 4)
[tex]f(x) = 2x - 6[/tex]
[tex]f(x - 4) = 2(x - 4) - 6[/tex]
[tex]f(x - 4) = 2x - 8 - 6[/tex]
[tex]f(x - 4) = 2x - 14[/tex]
Hence:
[tex]g(x) = 2x - 14[/tex]
Compress by 1/4 units
This means that the function is stretched by [tex]1/\frac{1}{4}[/tex]
Compressing a function is represented as:
[tex]g(x) =f(bx)[/tex]
In this case:
[tex]b = 1/\frac{1}{4}[/tex]
[tex]b = 1 * \frac{4}{1}[/tex]
[tex]b = 4[/tex]
Substitute expression for f(x) and 4 for b in [tex]g(x) =f(bx)[/tex]
[tex]g(x) =f(4x)[/tex]
Calculating f(4x)
[tex]f(4x) = 2(4x) - 6[/tex]
[tex]f(4x) = 8x - 6[/tex]
Hence:
[tex]g(x) = 8x - 6[/tex]

Can anyone please help me figure this problem out?
Answer:
x = 12
Step-by-step explanation:
Step(i):-
From graph,
The angle of the triangle ∝ = 45°
Given hypotenuse of the triangle
AC = 12√2 and AB = x
Step(ii):-
we will choose sine function
[tex]sin\alpha = \frac{opposite side}{hypotenuse}[/tex]
[tex]sin\alpha = \frac{x}{12\sqrt{2} }[/tex]
Given that an angle ∝ = 45°
[tex]sin45 = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{\sqrt{2} } = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{1 } = \frac{x}{12}[/tex]
x = 12
Final answer:-
x = 12

1. The President is hoisting the flag, but the line has gotten stuck. A
Hardy wants to fix it. He used a 15m ladder and placed it 9m away
base of flag pole. Find the height of flag.
Answer:
the height of the flag = 12cm
Step-by-step explanation:
inclide ladder length = 15m (hypotenuse)
distance between ladder foot and flag foot= 9m (base)
according to Pythagoras theorem,
(h)^2 = (p)^2 + (b)^2
(15)^2 = (p)^2 + (9)^2
(p)^2 = (15)^2 - (9)^2
(p)^2 = 225-81
p = √144
p= 12 cm
