What is the geometric possibility of being in the square and not in the circle? The radius of the circle is five inches. Express percent’s to the nearest tenth.
A. 21.5%
B. 23.0%
C. 20.0%
Answer: A
Step-by-step explanation:
The area of the square is 10^2 = 100.
The area of the circle is (pi)(5^2) = 25pi.
So, the area of the region in the square but not in the circle is 100 - 25pi.
Thus, the desired probability is (100-25pi)/100, which is about 21.5%

Eric surveys students at his school and finds that 80% have a pet. He wants to estimate the probability that, if he randomly selected 4 students, more than 2 would have a pet.
To estimate this probability, he lets the numbers 1, 2, 3, and 4 represent a student who has a pet and 5 represent a student who does not have a pet. He then has a computer randomly select 4 numbers and repeats this 20 times.
The results of these trials are shown in this list.
5533, 2245, 1555, 3341, 4252,5335, 5321, 4155, 2131, 3414,1532, 4251, 2523, 3311, 2352,2332, 5451, 3344, 1121, 5243
Based on this simulation, what is the estimated probability that more than 2 of 4 randomly selected students would have a pet?
Enter your answer, as a decimal, in the box.
==========================================================
Explanation:
You'll look at each four digit group separately.
Since we want more than 2 people having a pet, this means the group of four must have 3 pet owners or all 4 are pet owners.
The digit 5 represents "no pet". If we see it show up twice or more, then we must cross the group off the list. Something like 5533 has the first two people that don't own pets, while the last two people do own pets. In this case, we don't have a "more than 2 pet owners" situation happening. So we must cross it off the list.
Here is the list of groups to cross off
55331555533541555451There are five such groups we have eliminated. That leaves 20-5 = 15 groups where there are more than 2 pet owners.
We have 15 groups we want out of 20 total. It leads to the probability of 15/20 = 0.75

Start by calculating the slope (m) using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{14 - 2}{1 - 0}[/tex]
Evaluate
m = 12
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
y = 12(x - 0) + 2
Evaluate
y = 12x + 2

Write the equation of the circle in general form. Show all your work.
Answer:
(x + 3)^2 + (y - 2)^2 = 25
Step-by-step explanation:
Looking at the circle we can see the origin and the radius from the origin to the edge of the circle.
radius = 5
Origin of the circle (h,k) = (-3,2)
Equation of a circle: (x - h)^2 + (y - k)^2 =r^2
Plug in our (h,k) and radius into the equation.
(x - (-3))^2 + (y - (2))^2 = 5^2
(x + 3)^2 + (y - 2)^2 = 25
A ladder reaches 2 m up a wall. the foot of the ladder is 0.4 m from the wall. for safety reasons, the slope should be between 6.3 and 9.5. is this ladder within the safe range?
Answer:
No, the ladder is not within the safe range because the slope is 5.
Step-by-step explanation:
To solve, find the slope of the ladder using the slope formula and check if the slope is between 6.3 and 9.5.
What is slope?
Slope is how steep a line is. In this case, the line is the ladder. If the ladder is too steep, them it is not safe.
How do we calculate slope?You can calculate slope using the following formula:
[tex]slope = \frac{rise}{run}[/tex]
Rise means how faraway vertically, or how high up the ladder is.
Run means the how faraway horizontally, or from the wall the ladder is.
Slope of the ladderLet's calculate slope using the formula.
[tex]\displaystyle {slope=\frac{rise}{run}}[/tex]
[tex]\displaystyle {slope=\frac{2\ m}{0.4\ m}}[/tex] Substitute the values, 2m for rise, 0.4m for run.
[tex]\displaystyle {slope=5}[/tex] Final answer
Is the ladder safe?The question tells us that a safe ladder has a slope of 6.3 to 9.5. The slope, 5, is not between that range. Therefore, the ladder is not safe.

£20 is divided between June, Sushil &
Fiona so that June gets twice as much as
Sushil, and Sushil gets three times as
much as Fiona. How much does June get?
Answer:
Therefore, June gets £6
Step-by-step explanation:
Total amount = £20
Assume:
June's share = a
Sushil's share = b
Fiona's share = c
a = 2b -----------------------(1)
b = 3c -----------------------(2)
c = b ÷ 3 -------------------(3)
a + b + c = £20 --------(4)
Substitute equations (1) and (3) in equation (4)
2b + b + (b ÷ 3) = £20
10b ÷ 3 = £20
b = £20 * 3 ÷ 10 = £6
a = 2 * £6 = £12
c = £6 ÷ 3 = £3
Therefore, June gets £6

A baby giraffe was born at a wildlife preserve. The giraffe was 6 feet tall when it was born, and it grew 1.75 feet over the next 7 months.
If the giraffe continues to grow at the same rate, at what age will it reach a height of 15 feet?
The age of the giraffe when he is 15 feet tall be 1 year 1 month and 16 days.
What is fraction?
A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Giraffe height = 6 feet
Height grew in 7 months= 1.75 feet
Giraffe's height in 7 month = 7.75 feet
Giraffe's height, 1 feet= [tex]\frac{7}{7.75}[/tex] month
= 0.9032 months
Giraffe's height, 15 feet= 0.9032 x 15 month
= 13.548 month

A radio station has a broadcast area in the shape of a circle with equation x2+ y2=5,625, where the constant represents square miles.
a. Find the intercepts of the graph
Answer:
(0, 75), (75, 0), (-75, 0), (0, -75)
Step-by-step explanation:
I used desmos graphing calculator. c:
Triangle ABC is transformed. Select all the
transformations that would create a shape that is
congruent to ABC.
1. Reflection across the y axis
2.Dilation by scale factor of 1
3. Rotation 90 degrees clockwise
4. Translation 4 units to the right
Answer: All four answer choices would create congruent shapes.
===================================================
Explanation:
Reflections, rotations, and translations are considered rigid transformations. What this means is that they keep the same shape, but the shape has been moved in some fashion. As such, the "before" (preimage) and "after" (image) are congruent figures.
Imagine you drew a triangle on a clear piece of glass. If you took a picture of it from one side, then took another picture from the opposite side, then you'd get reflected versions of the triangle. Notice how the triangle has not moved at all. The camera has. Therefore, this proves that reflections keep the same exact shape. The only thing different is the orientation has swapped.
Now imagine you drew a triangle etched in stone. Grab your camera to take a picture of it. Then rotate the camera to get another picture. The two triangles are rotated copies of each other. They're the same exact triangle since the figure etched in stone hasn't changed. Only the camera has. This thought exercise proves rotations are a rigid transformation, aka an isometry.
Lastly, we'll go back to the triangle etched in stone to work with translations. A translation is any shifting. Take a picture of the triangle etched in stone. Then move the camera around to pan to another location (panning is when you keep your aim at the subject but move side to side, or up and down). Imagine the camera is stuck on a train track and can only aim one direction. The camera will take two pictures of the same triangle, of course the only difference is that they have shifted in the frame. Therefore, translations are the third final type of rigid transformation.
-----------------
Dilations are not rigid transformations, but only if the scale factor was something else than 1.
If the scale factor is less than 1, then the image shrinks.
If the scale factor is greater than 1, then the image enlarges.
If the scale factor is exactly 1, then the image doesn't change at all. This is because we multiplied all sides by 1. Multiplying by 1 doesn't change the number.
So because choice (2) mentions the scale factor is 1, this places it in the "rigid transformation" category and it's one of the four answers. Change the scale factor to anything else, and it wouldn't be an answer.
