Answer:
[tex]\large\boxed{P=(3\pi+4)\ ft}[/tex]
Step-by-step explanation:
We have 3/4 of a circle and the square.
The perimeter is equal to the sum of a 3/4 of a circumference of a circle and two sides of a square.
The formula of a circumference of a circle:
[tex]C=2\pi r[/tex]
r - radius
We have r = 2 ft. Substitute:
[tex]C=2\pi(2)=4\pi\ ft[/tex]
3/4 of a circumference:
[tex]\dfrac{3}{4}\cdot4\pi=3\pi\ ft[/tex]
The length of a side of a square is a = 2ft.
Calculate the perimeter:
[tex]P=3\pi+(2)(2)=(3\pi+4)\ ft[/tex]

Do you think this graph looks more like a quadratic or exponential function? Why do you think so?
Answer:
Exponential Function
Step-by-step explanation:
The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.
This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:
[tex]f(x)=f(0)(2)^{x}[/tex]
Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Answer:
a) 0.7486; b) 0.6518; c) No
Step-by-step explanation:
We use z scores to answer these questions. The formula for a z score is
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Our mean, μ, is 44; our standard deviation, σ, is 1.5.
For part a,
We want P(X > 43):
z = (43-44)/1.5 = -1/1.5 = -0.67
Using a z table, we see that the area under the curve to the left of this is 0.2514. However, we want the area to the right; this means we subtract from 1:
1 - 0.2514 = 0.7486
For part b,
We want P(42 ≤ X ≤ 45):
z = (42-44)/1.5 = -2/1.5 = -1.3
z = (45-44)/1.5 = 1/1.5 = 0.67
Using a z table, the area under the curve to the left of z = -1.3 is 0.0968. The area under the curve to the left of z = 0.67 is 0.7486.
The area between them is 0.7486 - 0.0968 = 0.6518.
For part c,
A response of 35 has a z score of
z = (35-44)/1.5 = -9/1.5 = -6
This is 6 standard deviations below the mean. This is more than the amount required to make this an outlier, or an unlikely response.

The length of the small leg of a 30 -60 -90 degree triangle is 5. What is the perimeter of the triangle?
Answer:
option (B)
15 + 5√3
Step-by-step explanation:
In a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.
Given in the question,
length of small leg = 5
As we know that
The hypotenuse is equal to twice the length of the shorter leg
hypotenuse = 2(5) =10The longer leg is equal to multiplying the shorter leg by the square root of 3
other leg = 5√3Perimeter of a triangle = sum of the length of three sides
= 5√3 + 10 + 5
= 15 + 5√3

The perimeter of a playing field for a certain sport is 320 ft. The field is a? rectangle, and the length is 48 ft longer than the width. Find the dimensions.
Answer:
length: 104 ftwidth: 56 ftStep-by-step explanation:
Let L and W represent the length and width of the field. Then the perimeter is given by ...
P = 2(L +W)
Filling in the given information, we have ...
320 = 2(L +W)
L = W +48 . . . . . . the length is 48 ft longer than the width
Using the second equation in the first, we get
320 = 2((W +48) +W)
320 = 4W +96 . . . . . . simplify
224 = 4W . . . . . . . . . . subtract 96
56 = W . . . . . . . . . . . . .divide by 4
L = 56 +48 = 104 . . . . find L using the above relation
The width of the field is 56 ft; the length is 104 ft.
The width of the playing field is 56 ft and the length is 104 ft.
Explanation:To solve this problem, let's set up an equation using the information given. Let's say the width of the field is x ft. Since the length is 48 ft longer than the width, the length can be represented as x + 48 ft. The formula for the perimeter of a rectangle is P = 2(l + w), so we can set up the equation: 320 = 2(x + 48 + x). Now, we can solve for x by simplifying and solving the equation.
320 = 2(2x + 48)
320 = 4x + 96
4x = 320 - 96
4x = 224
x = 224/4
x = 56
So, the width of the field is 56 ft and the length is 56 + 48 = 104 ft.
To solve this problem, we must use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
According to the question, the length is 48 ft longer than the width, therefore we could express the length as L = W + 48. The perimeter provided is 320 ft. Now we can plug these values into the perimeter formula.
320 = 2(W + 48) + 2W
After simplification, this formula becomes 320 = 4W + 96.
To isolate W, you subtract 96 from both sides to get: 320 - 96 = 4W + 96 - 96, which simplifies to 224 = 4W. Dividing both sides by 4 gives W = 56 ft. This is the width of the field. The length, then, is 56 ft + 48 ft = 104 ft (since the length is 48 ft longer than the width).
So, the dimensions of the field are 104 feet by 56 feet

After the elephant keepers switched to a new formula for daily feedings of the youngest elephants, the keepers tracked the elephants’ weight gains to make sure that it was within a desired range. Would a bar graph or a histogram be better for displaying this data?
A Histogram would be better for displaying the data
A histogram would be better for displaying the data of elephant calves' weight gains after the switch to a new formula for daily feedings.
Explanation:A histogram would be better for displaying the data of elephant calves' weight gains after the switch to a new formula for daily feedings. A histogram is useful for displaying the distribution and frequency of a continuous dataset, such as the weight gains of elephant calves. It can show how many calves fall within each weight range, and provide a visual representation of the desired range of weight gain.

A fair coin is tossed three times in succession. Find the probability if getting exactly one tail
Answer:
If a fair coin is tossed three times, sample = 2^3 = 8 (hhh, hht, hth, thh, htt, tht, tth, ttt) where h=head and t=tail.
Probability of getting one:
Outcomes with one head (h) = 3
P(1 h) = 3/8 = 0.375
The probability of getting exactly one tail when a fair coin is tossed three times in succession is 37.5%.
Explanation:The probability of getting exactly one tail when a fair coin is tossed three times in succession can be found using the binomial probability formula.
Let's denote success as getting a tail and failure as getting ahead. The probability of success, denoted as p, is 0.5 since the coin is fair and has an equal chance of landing on heads or tails. The probability of failure, denoted as q, is also 0.5.
Using the binomial probability formula: P(X = k) = [tex]C(n, k) * p^k * q^(n-k)[/tex], we can calculate the probability as follows:
n = 3 (number of trials) k = 1 (number of tails desired) C(n, k) = C(3, 1) = 3 (number of ways to choose 1 tail from 3 trials)[tex]p^k = 0.5^1[/tex] = 0.5 (probability of getting 1 tail)[tex]q^(n-k) = 0.5^(3-1)[/tex] = 0.25 (probability of getting 2 heads)Plug these values into the formula: P(X = 1) = 3 * 0.5 * 0.25 = 0.375 (or 37.5%)Therefore, the probability of getting exactly one tail when a fair coin is tossed three times in succession is 0.375 or 37.5%.

Need help please asp thank you so much
Answer:
x = -1, 3
Step-by-step explanation:
so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.
-x + 5 = x^2 - 3x + 2
you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.
0 = x^2 - 2x - 3
now you factor
0 = (x - 3) (x + 1)
x = -1, 3

Eight boys and seven girls showed up to one of the team's games. League rules limit each team to 10 players at a time (five girls and five boys) per game. Given this rule, how many combinations of 10 players are there among the 15 boys and girls who showed up at this particular game?
Answer:
1176 Combinations
Step-by-step explanation:
As mentioned in the question, there are total 8 boys and 7 girls.
Our objective is to create a team with 5 boys and girls each.
To select 5 boys out of 8, we will use combination.
=> 8C5 = [tex]\frac{8!}{5!(8-5!)}[/tex]
=> [tex]\frac{8.7.6.5!}{5!.3!}[/tex]
=> [tex]\frac{8.7.6}{6}[/tex]
=> 56
Similarly,
5 girls are selected using 7C5
=> 21
Therefore, the total combination of players are 56 * 21 = 1176
Describe how to translate the graph of g(x) = ln x into the graph of f(x)= ln (-5)+5
Answer:
B
Step-by-step explanation:
We know:
1. Replacing -x into x of an equations reflects the graph on the y-axis
2. If f(x) is a function, then f(x)+a is a vertically translated graph of the original graph, a units up
Looking at the original function of ln x and the transformed graph of ln(-x) +5, we see that we have replaced x with -x, which means it is a reflection across the y-axis.
Also, we have added a five after the function, so that means it is a vertical translation of 5 units up.
Looking at the answer choices, we see that B is the correct answer.

x² - 4x = -3 now solve this quadratic for x...
x² - 4x + 3 = 0
factor...
(x - 3)(x - 1) = 0,
so at x = 1 and x = 3, the function crosses the x-axis
See the graph below
Yes, because the center is on the x-axis, the circle will intersect 2 times, at x=1 and at x=3
