the temperature of the first 6 days in march is shown below. if the temperature 23 F is removed from below, how much greater is the range of the original 6 temperatures than the range of the 5 temperatures:
23F 58F 62F 64F 64F 65F
a. 35
b. 42
c. 7
d. 23
Answers
Given:
The temperature of the first 6 days in march is:
23F, 58F, 62F, 64F, 64F, 65F
23 F is removed from the data set.
To find:
How much greater is the range of the original 6 temperatures than the range of the 5 temperatures.
Solution:
Range of a data set is:
Range = Maximum value - Minimum value
The given data set is:
23 F, 58 F, 62 F, 64 F, 64 F, 65 F
The range of given data set is:
Range = 65 - 23
= 42
If the temperature 23 F is removed from the data set, then the new data set is:
58 F, 62 F, 64 F, 64 F, 65 F
The range of this new data set is:
Range = 65 - 58
= 7
Now, the difference between original range and new range is:
[tex]42-7=35[/tex]
The original range is 35 more than the new range. Therefore, the correct option is a.

A tepee is designed to have a diameter of 10 feet and the volume of 419 ft.³ at what height the support poles crossed with some of the tepee correctly?
Answers
Answer:
The required height is equal to 5.33 feet.
Step-by-step explanation:
Given that,
Diameter, d = 10 feet
Volume, V = 419 ft.³
We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.
The tepee is in the form of a cylinder. The volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]
So, the required height is equal to 5.33 feet.

sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
So in #1:
We have the angle and hypotenuse and need to solve for the side opposite of the angle. This smells like a sine question.
sin(42)=x/25
this means that x=25sin(42). Plug that into the calculator and get: 16.73.
(Make sure you are in degrees mode)
For #2:
We are given the angle, the opposite side, and have to solve for the adjacent side. Looks like we need the tangent.
tan(75)=12/x
This means that x=12/tan(75). Calculator says: 3.22
For #3:
We have the angle, adjacent, and have to solve for the hypotenuse. This would be a cosine.
cos(36)=19/x
Solve for x: x=19/cos(36). Calculator says: 23.49
For #4:
We have the angle, adjacent side, and need the opposite side. This is another tangent problem.
tan(53)= x/7
Solving for x: x=7tan(53). Calculator says: 9.29

The equation of two circles are known, circle A’s equation is (x-3)^2+(y+4)^2=9 and circle B’s equation is (x+4)^2+(y+12)^2=8.
What is the radius of circle A and the radius of circle B.
Answers
Answer:
Step-by-step explanation:
The circles are written in standard form. The standard form squares the radius on the right hand side.
Circle A
radius = sqrt(9)
radius = 3
Circle B
radius = sqrt(8)
radius = sqrt(2 * 2 * 2)

initial Population, Po = 400
Final population, P = 2000
Let the time is t.
[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

Find an angle α that is coterminal with an angle measuring −460∘, where 0∘≤α<360∘. Do not include the degree symbol in your answer. For example, if your answer is 20∘, you would enter 20.
Answers
Answer:
The coterminal angle is 260°
Step-by-step explanation:
Suppose that we have an angle A.
All the coterminal angles to A are written as:
B = A + n*360°
Where n is any whole number.
Notice that if n = 0, we get:
B = A + 0*360° = A
So A is coterminal with itself, which is trivial.
Now we want to find a conterminal angle to -460° such that it is in the range:
0° < α < 360°
So we just need to find a value of n such that:
α = -460° + n*360°
is on the given range.
We can assume that n = 2 will work, let's check:
α = -460° + 2*360° = 260°
α = 260°
And this angle is in the given range:
0° < 260° < 360°

Step-by-step explanation:
Here is the complete question
here are 2 yellow, 3 green, 1 orange, and 4 red cards in a stack of cards turned facedown. Once a card is selected, it is not replaced. Find each probability.
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
1. P(two yellow cards)
there are a total of 10 cards and 2 yellows cards. If 1 yellow card is picked, it would remain 1 yellow card and 9 cards
P(two yellow cards) = 2/10 x 1/9 = 1/45
