An engineer estimated the weight of a steel beam to be 150 pounds. The actual weight of the beam was 143 pounds.
Find the absolute error and the percent error of the engineer's estimate. If necessary, round your answers to the nearest tenth.
absolute error = ? (pounds)
percent error = ? (%)
Answer:
absolute error: 7 pounds
percent error:4.9%
Step-by-step explanation:
Absolute error:
150-143=7 pounds
Percent error:
=l[tex]\frac{150-143}{143}[/tex] l x 100
=l[tex]\frac{7}{143}[/tex]l x 100
=0.04895x100
=4.895...
=4.9%
n airline company charges the following baggage fees: $25 for the first bag and $35 for the second (i.e., you pay $60 if you check two bags). Suppose 54% of passengers have no checked luggage, 34% have one piece of checked luggage and 12% have two pieces. About how much revenue should the airline expect for a flight of 120 passengers
Answer:
The airline should expect a revenue of $1,884 for a flight of 120 passengers
Step-by-step explanation:
For each passenger:
54% of passengers have no checked luggage, that is, 54% probability of no revenue.
34% have one piece, that is, 34% probability of $25 revenue.
12% have two pieces, that is, 12% probability of $60 revenue.
The expected revenue for a single passenger is:
[tex]E = 0.54*0 + 0.34*25 + 0.12*60 = 15.7[/tex]
For 120 passengers
15.7*120 = $1,884
The airline should expect a revenue of $1,884 for a flight of 120 passengers
PLS HELP I HAVE BEEN ASKING FOR 4 DAYS IM JUST GETTING BAD ANSWERS I WILL GIVE BRAINLIEST. IM ABOUT TO FAIL :((((((((((((((
Answer:
29 day) $15.00
30 day $15.00
31 day $15.00
The cost was the same for all three days
Step-by-step explanation:
Rover = 3/4 can
Bobo = 1/2 can
29(3/4) + 29(1/2) = 21.75 + 14.5 = 36.25 cans
36.25/3 = 12.08
must buy 4 packs of 3 at $5.00 each = $15.00
30(3/4) + 30(1/2) = 22.5 + 15 = 37.5 cans
37.5/3 = 12.5
must buy 4 packs of 3 at $5.00 each = $15.00
31(3/4) + 31(1/2) = 23.25 + 15.5 = 38.75 cans
38.75/3 = 12.92
must buy 4 packs of 3 at $5.00 each = $15.00

2. The area A of a circle is increasing at a constant rate of 2.5cm s . If the area of the circle is given
by A = πr2, what is the rate of change of the radius when the radius is 15cm?
Answer:
235.65 cm^2s-1
Step-by-step explanation:
We have that;
Rate of change of area (dA/dt) = (dA/dr) (dr/dt) By chain rule
Note that dr/dt = rate of change of radius
But
A = πr^2
dA/dr = 2πr
dr/dt = 2.5cm s-1 (given)
So;
dA/dt = 2πr * 2.5cm s-1
r = 15cm (given)
dA/dt = 2 * 3.142 * 15cm * 2.5cm s-1
dA/dt = 235.65 cm^2s-1

Paige only needs to sell to 17 more customers to receive a bonus. She works part time, so she only talks to 50 customers per day. With a sales ratio of 1:9, on which day will Paige qualify for a bonus?
Answer:
Paige will qualify for a bonus on her 4th day of work.
Step-by-step explanation:
50 customers per day
needs to sell to 17
Ratio = 1:9
1:9
×17 ×17
17:153
Paige needs to see 153 customers.
153 ÷ 50 = 3.06 ≈ 4 (As the answer is not asking for the exact number of the day you round up to make a whole day without underestimating)
So, Paige will qualify for a bonus on her 4th day of work.
Find the measures of all the interior angles of the non-convex figure below.
Answer:
angle 3x = 78°
angle opposite (4x + 30) = 226°
Step-by-step explanation:
It has 6 sides, so:
total interior angles sum = (180° x 6) - 360° = 720°
720° = 90° + 3x + 90° + 118° + (360° - (4x + 30°)) + 118°
combine like terms:
720° = 3x + 416° + (360° - 4x - 30°)
720° = -x + 746°
x = 26°

What is the area in square inches of the shaded area? Use 3.14 for π and round your answer to the nearest whole number.
Answer:
Area of shaded region=2 ×3.14×R -2×3.14×r(where R is lager radius and r is smaller radius.)
Therefore area of shaded region=2×3.14×12 -2×3.14×8
=2×3.14(12-8)
=6.18 ×4

Answer:
f(x) = 4*(5/2)^x
Step-by-step explanation:
First, we know that our function has the points:
(0, 4)
(1, 10)
(2, 25)
The first one (0, 4) means that:
f(0) = 4.
Then you can evaluate the four given functions in x = 0 and see which ones meet this condition (have the outcome equal to 4)
Here we can discard the function f(x) = 15*x - 5 because:
f(0) = 15*0 - 5 = -5
Then this function is discarded.
Now let's look at the second point, (1, 10)
This means that f(1) = 10
Then you can evaluate the remaining functions in x = 1, and see if the outcome is equal to 10.
Here we can discard the first function f(x) = (x + 2)^2 because:
f(1) = (1 + 2)^2 = 3^2 = 9
So the output is not 10 as we wanted.
(while for the other two functions we have)
for f(x) = 6*x + 4
f(1) = 6*1 + 4 = 10
for f(x) = 4*(5/2)^x
f(1) = 4*(5/2)^1 = 4*(5/2) = (4/2)*5 = 10
Now we use the last point, (2, 25)
This means that when x = 2, the outcome needs to be equal to 25.
For the function f(x) = 6*x + 4 we have:
f(2) = 6*2 + 4 = 12 + 4 = 16
So we can discard this one.
Then we could conclude that the remaining option is the correct one, but let's ceck.
f(x) = 4*(5/2)^x
then for x = 2
f(2) = 4*(5/2)^2 = 4*(25/4) = 25
correct.
Then the correct option is f(x) = 4*(5/2)^x

What does x equal
3х – 4 = 8 + 2х
Answer: x = 12
Step-by-step explanation:
First, we have to add 4 on both sides of the equation to combine like terms:
3х – 4 (+4) = 8 (+4) + 2х
3x = 12 + 2x
Now we subtract 2x on both sides of the equation, which leaves x by itself:
3x (-2x) = 12 + 2x (-2x)
x = 12

A billard ball has a surface area of 84 square centimeters. What is the radius of the ball?
Answer: √21/√pi
Step-by-step explanation: Surface area of ball is 4(pi)r^2. Divide 84 by 4 and get 21. Dividing 21 by pi and taking the square root therefore is the answer.
