Answer: 1 over 20
Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.
If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)
So if we mutiply 1/4 and 1/5, we get 1/20
That is how I arrived at my answer of 1 over 20

Answer:
5
Step-by-step explanation:
To find the median, write down all numbers in numerical order and cross off one number from each side until you are left with the middle number.
One thing to keep in mind when doing this, though, is to make sure you cross off the same amount on each side, and if you have 2 numbers left, like 13 and 14, your answer would be the number exactly between those, 13.5.
Hope this helps :)
One airplane is approaching an airport from the north at 164 km/hr. A second airplane approaches from the east at 271 km/hr. Find the rate at which the distance between the planes changes when the southbound plane is 28 km away from the airport and the westbound plane is 17 km from the airport.
Answer:
The rate of change of the distance between the airplanes is approximately 316.760 kilometers.
Step-by-step explanation:
The distance between both airplanes (r), in kilometers, can be determined by the Pythagorean Theorem, that is:
[tex]r^{2} = x^{2}+y^{2}[/tex] (1)
Where:
[tex]x[/tex] - Distance of the westbound airplane from airport, in kilometers.
[tex]y[/tex] - Distance of the southbound airplane from airport, in kilometers.
By Differential Calculus, we derive an expression for the rate of change of the distance between the airplanes ([tex]\dot r[/tex]), in kilometers per hour:
[tex]2\cdot r\cdot \dot r = 2\cdot x \cdot \dot x + 2\cdot y \cdot \dot y[/tex]
[tex]\dot r = \frac{x\cdot \dot x + y\cdot \dot y}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
Where:
[tex]\dot x[/tex] - Rate of change of the distance of the westbound airplane, in kilometers per hour.
[tex]\dot y[/tex] - Rate of change of the distance of the southbound airplane, in kilometers per hour.
If we know that [tex]x = 17\,km[/tex], [tex]y = 28\,km[/tex], [tex]\dot x = -164\,\frac{km}{h}[/tex] and [tex]\dot y = -271\,\frac{km}{h}[/tex], then the rate of change of the distance between the airplanes is:
[tex]\dot r = \frac{x\cdot \dot x + y\cdot \dot y}{\sqrt{x^{2}+y^{2}}}[/tex]
[tex]\dot r \approx -316.760\,km[/tex]
The rate of change of the distance between the airplanes is approximately 316.760 kilometers.

what is the correct solution to-3x < 21?
Answer:
x > - 7
Step-by-step explanation:
Given
- 3x < 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x > - 7
The solution of inequality - 3x < 21 is,
⇒ x > - 7
We have to given that,
The inequality is,
⇒ - 3x < 21
We can simplify the inequality as,
⇒ - 3x < 21
Divide 3 both side,
⇒ - 3x /3 < 21 / 3
⇒ - x < 7
Take - 1 as common,
⇒ - x < 7
⇒ x > - 7
Therefore, The solution of inequality - 3x < 21 is,
⇒ x > - 7

Jordan earned $200 this month delivering newspapers. His mom said he must put 20% into his savings account. He wants to buy headphones that cost $ 99.95 and two shirts that cost \$17 each. He also has to pay 7% sales tax on his purchases . Jordan said, "No problem. I will put 20% into savings , buy the things I want, and still have about $10 left." Use estimation to determine if Jordan's calculation is reasonable. Show your work.
Answer:
Yes, his calculation is reasonable. He will have about $16.67 left.
Step-by-step explanation:
200 - (200 * .2) = $160 Subtract money for savings
99.95 + (99.95 * .07) + (17*2) + (17 * .07) + (17 * .07) = $143.33 Add taxes
160 - 143.33 = $16.67 Subtract money for purchases from money left after savings

Answer:
7 1/3 hours
Step-by-step explanation:
We are to assume that the total number of heater-hours required is a constant. That is, the time is inversely proportional to the number of heaters.
If the number of heaters goes up by a factor of 6/4 = 3/2, then the number of hours will go down by the inverse factor: 2/3.
With 6 heaters instead of 4, the time required is (2/3)(11 hours) = 7 1/3 hours.

The graph of f(x) = 0.4x is replaced by the graph of g(x) = 0.4x + k. If g(x) is obtained by shifting f(x) up by 4 units, then what is the value of k?
Answer:
The value of k=4
Step-by-step explanation:
we have
f(x)=0.4x
This function represent a linear direct variation (The line passes through the origin)
we know that
If f(x) is shifting up by 4 units
then
The y-intercept of the function will be the point (0,4)
therefore
The function g(x) will be -----> g(x)=0.4x+4 (equation of the line into slope
intercept form)
The rule of the translation
f(x) --------> g(x)
(x,y) -------> (x,y+4)
The translation is 4 units up
therefore
The value of k=4

8. Find the values of the variables.
a. x = 39.6, y = 10.6
b. x = 10.6, y = 39.6
c.x= 42.4, y = 158.4
d. x 158.4, y = 42.4
Answer:
x = 10.6, y = 39.6
Step-by-step explanation:
Given that,
Angle A = 75°
Angle B = 90°
Angle C = 180-(A+B)
= 15°
Now, using trigonometry,
[tex]\sin C=\dfrac{x}{41}\\\\x=41\times \sin C\\\\=41\times \sin(15)\\\\x=10.6[/tex]
For y, using Pythagoras theorem,
[tex]y=\sqrt{41^2-10.6^2} \\\\y=39.6[/tex]
Hence, the value of x is equal to 10.6 and that of y is equal to 39.6.

which number best represents the slope of the graphed line?
Answer:
If you have choices it is either -5 or 5.
Step-by-step explanation:
First, you find two points, which mine were (0,2) and (-1,7). The slope formula is y2 - y1 divided by x2 - x1. So, im going to subtract 7 - 2, which is your y2 - y1, to get 5. Then, i'm going to subtract -1 - 0, which is your x2 - x1, to get -1. Then, you divide 5 by -1 to get -5. I Hope This Helps :)

580
Step-by-step explanation:
I wanted to use the Pythagoras theory but I noted that they've given us the hypotenuse which is 8.6 they have already given us the height is 7 and the base is 5 when you use the Pythagoras theory you'll find that there hypotenuse is 8.6 that's why I wrote forget it there's no need of finding the base and the height for the other triangle just transfer 7 and 5 then calculate the volume I guess I got the answer is 580 hope it helps you good day.

TExit Statistics & Probability - 1/5 The Jackson family has 4 kids, 4 boys and 0 girls. Suppose that for each birth, the probability of a boy birth is 1/2, and the probability of a girl birth is also 1/2. What is the fractional probability of having 4 boys and 0 girls, in any order, in a family's first 4 births?
Answer:
The fractional probability of having 4 boys and 0 girls, in any order, in a family's first 4 births is 1/16
Step-by-step explanation:
Total number of kids in Jackson family = 4 (4 boys and 0 girls)
Probability of having a boy = 1/2 =0.5
Probability of having a girl = 1/2 =0.5
Fractional probability of having 4 boys and 0 girls in any order
(1/2*1/2*1/2*1/2) + 0
= 1/16
What is 5600 in expanded from
The expanded form of a number is every digit with its own zero's and its own SINGLE digit. For example, the expanded form of 12 is 10+2=12, or the expanded form of 13498 is 10000+2000+400+90+8=13498.
We can now figure out that 5600 in expanded form is 5000+600+00+0=5600, but the extra 00+0 is not neccessary, so our final answer is 5000+600=5600
