The 4 members of a robotics team held a car wash to raise money. To attract customers, each person held a sign by the road for an equal portion of the car wash, which lasted 3 hours in all.
Answer:
3/4 or 45 minutes each
Step-by-step explanation:
3 hours are equivalent to 180 minutes which you can then divide by 4. 180/4=45. 45/60 when simplified completely equals 3/4 of an hour
A study concluded that among people with a certain virus, 99.2% of tests conducted were (correctly) positive, while for people without the virus, 97.9% of the tests were (correctly) negative. If 32% of patients actually carry the virus, what's the probability that a patient testing negative is truly free of the virus?
Answer:
Following are the solution to the question:
Step-by-step explanation:
The probability of virus P(V) =0.32
No virus P(NV) =0.66
Patient testing of negative P(TN) = virus, and negative testing+no virus and negative testing
[tex]=0.32(1-0.992)+0.66 \times 0.979 \\\\=0.00256+0.64614\\\\=0.6487[/tex]
This is why the likelihood of a patient being free of the virus is negative.
[tex]= \frac{P(NV) \times\ tested \ negative }{P(TN)}[/tex]
[tex]= \frac{0.66 \times 0.979}{0.6487}\\\\= \frac{0.64614}{0.6487} \\\\=0.996053646[/tex]

An economist modeled the demand Q for a certain product as a linear function of the selling price p the demand was 20000 units when the selling price was $40 per unit and the demand was 15,000 units when the selling price was $60 per unit based on the model what is the time and in units when the selling price is $55 per unit
Answer: 16,250 units.
Step-by-step explanation:
This is a linear function which means that it takes the form of y = mx + c.
Y is the demand
X is the price
Find m.
= (Y₂ - Y₁) / (X₂ - X₁)
= (15,000 - 20,000) / (60 - 40)
= -250
Find c using substitution;
20,000 = -250 * 40 + c
20,000 = -10,000 + c
c = 20,000 + 10,000
c = 30,000
Linear function is;
y = -250x + 30,000
If selling price is $55;
y = -250 * 55 + 30,000
y = 16,250 units.
The demand is 17000 units when the selling price is $55 per unit
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let Q represent the demand and P represent the selling price.
20000 units for selling price of $40, hence (40, 20000). 16000 units for selling price of $60, hence (60, 16000).
Hence:
[tex]Q-Q_1=\frac{Q_2-Q_1}{P_2-P_1}(P-P_1)\\\\Q-20000=\frac{16000-20000}{60-40}(P-40)\\\\Q=-200P+28000[/tex]
For P = 55 unit:
W
Q = -200(55) + 28000 = 17000
The demand is 17000 units when the selling price is $55 per unit

The base of tyler's cabin is a 56 feet by 78 feet rectangle. What is the area of the base of tyler's cabin?
Strategy:
why did you choose this strategy:
======================================================
Explanation:
Check out the diagram below
I drew a rectangle with dimensions 56 ft by 78 ft.
Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8
The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point
In the upper left corner, we have an area of 50*70 = 3500. Note how this is basically 5*7 = 35, but we tack on the two zeros (from 50 and 70 combined)In the upper right corner, we have an area of 70*6 = 420In the lower left corner, we have an area of 50*8 = 400In the lower right corner, we have an area of 6*8 = 48Add up all the areas found: 3500+420+400+48 = 4368
As a way to check, using your calculator shows that 56*78 = 4368
Write the slope of a line perpendicular to y=-6x+4. Explain why it is perpendicular
Answer:
1/6 is the slope since you have to flip it
Step-by-step explanation:
Answer:
The slope of a line perpendicular to the equation is 1/6 or x/6.This is perpendicular because it is the reciprical of the other equation
Step-by-step explanation:
y=-6x+4.
the slope intercept form is y=mx+b
m is the slope
m=-6
for the equation to be perpendicular then the slope is the reciprical
Knowing this lets find a line perpendicular to this equation
Equation:
y=1/6x+2/3
or
y=x/6+2/3
x+8y
units
8x -x+5y units
what’s the perimeter?
Answer:
P = 16x+26y units
Step-by-step explanation:
Let the length is (x+8y) units
Width = (8x-x+5y) units
We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.
P = 2[(x+8y) + (8x-x+5y)]
= 2[(8x+8y+5y)]
= 2[8x+13y]
= 16x+26y
Hence, the required perimeter is 16x+26y.

Robin invested $1000 in a 12% simple interest savings deposit for 3
years. He also invested an equal amount in a 10% compound interest
savings deposit for 3 years. At the end of 3 years, how much more
interest did he get from the simple interest deposit?
Step-by-step explanation:
Lets find out,shall we?
Simple interest=(PRT)/100
=$1000×12×3)/100
=$360
Now for compound interest
A=P(1+R/100)^t
A=$1000(1+12/100)^3
A=$1404.928
so interest for compound interest=$(1404.928-1000)=$404.928
Clearly,Robin got more interest by compound interest than simple interest which business people understand lol.
Difference in interest=$404.928-360=$44.928

Example 3: The following data was collected by a taxi driver who was interested in how much fuel he used on different journeys. Length of journey 100 250 150 180 220 (miles) 300 Fuel Used (liters) 24 59 44 50 59 97 Estimate how much fuel would be needed for a 200-mile journey.
Answer:
For a 200 mile journey, 55.5 liters of fuel
is needed
Step-by-step explanation:
Here, we want to estimate the fuel needed for a 200 mile journey
we can use this by having an average
By adding all and dividing by 6
Mathematically, that will be;
(24 + 59 + 44 + 50 + 59 + 97)/6
= 55.5
The reason for this is because if we added all the lengths and divide by 6, what we get is 200
Thus, if we added the liters of fuel used per each and divide by 6, we can have an estimate for a 200-mile journey

On a computer screen, Jennifer just created a triangular design of banner with vertices at A (-4,3) B(-1,5) and C (-1,2) she can use the computer software to perform transformations on this design. Which sequence of two transformations could she perform so that the transformed vertices become A (4,-5) , B (7,-7) and c (7,-4)
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, reflection, translation and rotation.
Given the vertices A (-4,3) B(-1,5) and C (-1,2).
If the vertices is reflected across the y = -1 line, the new location would be at:
A' (-4, -5). B'(-1, -7) and C'(-1, -4)
If it is then translated 8 units to the right i.e. (x, y) ⇒ (x + 8, y), the new location would be at:
A"(4, 5), B"(7, -7) and C"(7, -4)

Ifangle1∠ 1 and angle2∠ 2 are complementary, find the measure of x and the measures of the angles when LaTeX: m\angle1=\left(6x+5\right)^\circm ∠ 1 = ( 6 x + 5 ) ∘ and LaTeX: m\angle2=\left(8x+15\right)^\circm ∠ 2 = ( 8 x + 15 ) ∘ ?
Answer:
x = 5Step-by-step explanation:
The sum of two complementary angle is 90 degrees. Given the following complementary angles;
<1 = 6x + 5
<2 = 8x + 15
<1 + <2 = 90 (complementary angles)
6x + 5 + 8x + 15 = 90
14x + 20 = 90
14x = 90-20
14x = 70
x = 70/14
x = 5
Hence the measure of x is 5

Answer:
A
Step-by-step explanation:
Using the sine ratio on the right triangle on the right to find x
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{70}[/tex] ( multiply both sides by 70 )
70 × sin30° = x , thus
x = 35
-----------------------------------------------
Using the sine ratio on the right triangle on the left to find y
sin42° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{35}{y}[/tex] ( multiply both sides by y )
y × sin42° = 35 ( divide both sides by sin42° )
y = [tex]\frac{35}{sin42}[/tex] ≈ 52.3 ( to the nearest tenth ) → A
Answer:
y = 52.3.
Step-by-step explanation:
Consider the larger triangle on the right:
sin 30 = x / 70
x = 70 sin 30 = 70 * 0.5
= 35.
So, considering the small triangle:
Sin 42 = 35/y
y * sin 42 = 35
y = 35 / sin 42
y = 52.3.

There are 3 red marbles, 2 blue marbles, and 7 black marbles if you choose one marble, what is the probability that it will be a red marble?
Answer:
3:12
Step-by-step explanation:
3 + 2 + 7 = 12
3 = red marbles
12 = total marbles
Answer:
Probability of both red =3(182)=3(18!2!16!)=3153
Step-by-step explanation:
Let Ai be the event in which the i-th ball you grab is red. For the first ball you choose, you have 3 red marbles out of a total of 18. Therefore,
P(A1)=318.
For the second marble you grab, given that you already took a red one, that is, given A1, you have 2 red balls out of a total of 17, then
P(A2∣A1)=217.
Finally,
P(A1∩A2)=P(A1)P(A2∣A1)=318217=151.
