kathy has a semi-circle shaped garden that she wants to put a fence around. The diameter of the gardrn is 12 feet. How much fencing does she need?
Answer: 30.84 feet
This value is approximate. I used pi = 3.14
=====================================================
Explanation:
Consider a full circle of diameter 12 feet. The circumference is
C = pi*d
C = 3.14*12
C = 37.68
This is the approximate perimeter around the circle. Use more decimal digits of pi to get a more accurate value. You could also use your calculator's stored value of pi.
Since she has a semicircle, aka half circle, this means we cut that value in half to get 37.68/2 = 18.84
The distance around the curved portion of her garden is roughly 18.84 feet
Add on the straight line portion (the diameter) to get 18.84+12 = 30.84 feet
On Roberto’s shelf he has 6 mystery books, 5 science fiction, 4 history and 3 adventure. Roberto will randomly choose 1 book to read. What is the probability that he will choose an adventure book?
Answer:
3/18, or simplified, he has a 1/6 chance of grabbing an adventure book.
Step-by-step explanation:
6 + 5 + 4 + 3 = 18. There's 3 adventure books, which makes it so that he has a 3/18 chance of it being an adventure book. How did I simplify? 18 ÷ 3 = 6, 3 ÷ 3 = 1.

experimental and quasi-experimental designs are similar in what aspect of the design?
Experimental and quasi-experimental designs share similarities in terms of their focus on investigating cause-and-effect relationships. These designs both involve manipulating variables and observing their effects on an outcome of interest.
However, they differ in terms of the level of control the researcher has over the assignment of participants to groups. Experimental designs are characterized by the random assignment of participants to different groups or conditions. This randomization helps ensure that any observed differences between groups can be attributed to the manipulation of the independent variable. The researcher has control over the assignment process, allowing for stronger causal inferences. Quasi-experimental designs, on the other hand, lack the random assignment of participants to groups. This may be due to practical or ethical reasons. Instead, participants are assigned to groups based on pre-existing characteristics, such as age or location. While quasi-experimental designs still allow for the examination of cause-and-effect relationships, they are considered less rigorous than experimental designs due to the potential for confounding variables. In summary, experimental and quasi-experimental designs both aim to investigate cause-and-effect relationships. They differ primarily in the level of control the researcher has over participant assignment. Experimental designs use random assignment for greater control, while quasi-experimental designs rely on pre-existing characteristics.

Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

if a restaurant purchases organic food there is a 59% chance it will go bankrupt. if a restaurant does not purchase organic food there is a 60% chance it will go bankrupt. only 4% of businesses purchase organic food. when a restaurant goes bankrupt what is the probability it purchased organic food?
When a restaurant goes bankrupt the probability it purchased organic food is 0.04
By using the formula for Probability:
\(P(B|A) = \frac{P(AB)}{P(A)}\)
In which
P(B|A) is the likelihood that event B will occur in the absence of event A.
P(A/B) is the likelihood that both A and B will occur.
P(A) denotes the likelihood that A will occur.
Event A: Goes bankrupt
Event B: Purchase organic food.
Probability it goes bankrupt:
59% of 4%(purchases organic food)
60% of 96%( don't purchase organic food).
So,
P(A) = 0.59*0.04 + 0.6*0.96
P(A) = 0.5996
Bankrupt when purchases organic food. So
59% of 4%
P(A|B) = 0.59*0.04 = 0.0236
The likelihood that a restaurant bought organic food before it went out of business
\(P(B|A) = \frac{P(AB)}{P(A)}\) = 0.0236/0.5996 = 0.0393
When a restaurant goes bankrupt the probability it purchased organic food is 0.04.

The Cartesian coordinates of a point in the xy plane are (-4.7, -1.4). Find the polar coordinates of the point.
The polar coordinate of the point is (4.941, 16.65°).
Given the Cartesian coordinates of a point in the xy plane is (-4.7, -1.4). Find the polar coordinates of the point.
Polar coordinates:
Polar coordinates of a point is of the form (r,θ) where r is the radial distance from the origin to the point, and θ is the angle formed between the line joining the origin and the point, and the positive x-axis.
Now, we have to find the value of r and θ.
Let us first find the value of r.r = sqrt(x^2 + y^2)
where x = -4.7, y = -1.4r = sqrt((-4.7)^2 + (-1.4)^2)r = sqrt(22.45 + 1.96)r = sqrt(24.41)r = 4.941
Now, to find the value of θ, we use the formulaθ = tan-1(y/x)
where x = -4.7, y = -1.4θ = tan-1(-1.4/-4.7)θ = tan-1(0.2979)θ = 16.65°

Yes, there is enough sample evidence to conclude that the proportion of left-handed women is less than the proportion of left-handed men.
To test this conclusion, we can conduct a hypothesis test at the 0.05 level of significance. The null hypothesis would be that the proportions of left-handed women and men are equal, while the alternative hypothesis would be that the proportion of left-handed women is less than the proportion of left-handed men.
We would calculate the difference in proportions of left-handed women and men in our sample and then use a two-tailed z-test to determine if this difference is statistically significant. If the z-score we calculate is greater than the critical z-score associated with the 0.05 level of significance, then we can reject the null hypothesis and conclude that the proportion of left-handed women is less than the proportion of left-handed men.

4.4 a coin is biased such that a head is three times as likely to occur as a tail. find the expected number of tails when this coin is tossed twice.
To find the expected number of tails when the coin is tossed twice, we need to use the formula for expected value:
E(X) = ∑xp(x)
Where x is the possible outcome and p(x) is the probability of that outcome occurring.
Since a head is three times as likely to occur as a tail, the probability of getting a tail is 1/4 and the probability of getting a head is 3/4.
So, when the coin is tossed twice, there are four possible outcomes: two tails (TT), two heads (HH), one tail and one head (TH), and one head and one tail (HT).
The expected value of tails for each outcome is:
E(TT) = 2(1/4)(1/4) = 1/8
E(HH) = 0(3/4)(3/4) = 0
E(TH) = 1(1/4)(3/4) = 3/16
E(HT) = 1(3/4)(1/4) = 3/16
So the expected number of tails when the coin is tossed twice is:
E(X) = 1/8 + 0 + 3/16 + 3/16 = 7/16
Therefore, the expected number of tails when this coin is tossed twice is 7/16.

Galileo Galilei is said to have dropped cannonballs of different sizes from the Tower of Pisa to demonstrate that their speed is independent of their mass. The function h(t)- 189.27-16t² models the heighth (in feet) of the cannonball above the ground t seconds after it is dropped. Use the function to find the average speed of the cannonball during the following time intervals (a) The first 2 seconds 63 X ft/s (b) The first 3 seconds ft/s (c) Between t- 2 and t-3.25 ft/s
The average speed of the cannonball during the given time intervals can be calculated using the height function h(t) = 189.27 - 16t². (a) The average speed of the cannonball during the first 2 seconds is 63 ft/s. (b) The average speed of the cannonball during the first 3 seconds is 96 ft/s. (c) The average speed of the cannonball between t = 2 and t = 3.25 seconds is approximately 14.96 ft/s.
To find the average speed during a given time interval, we need to calculate the change in height (Δh) divided by the change in time (Δt). In this case, the height function h(t) is given as h(t) = 189.27 - 16t².
(a) For the first 2 seconds, we have Δh = h(2) - h(0) = (189.27 - 16(2)²) - (189.27 - 16(0)²) = 63. The change in time is Δt = 2 - 0 = 2 seconds. Therefore, the average speed is Δh/Δt = 63/2 = 31.5 ft/s.
(b) For the first 3 seconds, we have Δh = h(3) - h(0) = (189.27 - 16(3)²) - (189.27 - 16(0)²) = 96. The change in time is Δt = 3 - 0 = 3 seconds. Therefore, the average speed is Δh/Δt = 96/3 = 32 ft/s.
(c) To calculate the average speed between t = 2 and t = 3.25 seconds, we need to find Δh and Δt for this time interval. Δh = h(3.25) - h(2) = (189.27 - 16(3.25)²) - (189.27 - 16(2)²) ≈ -14.96. The change in time is Δt = 3.25 - 2 = 1.25 seconds. Therefore, the average speed is Δh/Δt ≈ -14.96/1.25 ≈ -11.97 ft/s.
Note: The negative sign indicates that the cannonball is moving downward during this time interval.
