The distance around the bases in meters will be 27.432 meters.
How many meters are in 1 feet?
In one feet there are 0.3048 meters.
Given is a baseball field measures 90 feet between each base.
Distance between each base in feet = [d] = 90 feet
The distance between each base in meters will be -
D [meters] = 90 x 1 ft
D [meters] = 90 x 0.3048 meters
D [meters] = 27.432 meters
Therefore, the distance around the bases in meters will be 27.432 meters.

Find the angle measures.

2
The angle measures are ∠1 = 66°, ∠2 = 114°.
Given that m<1 = (x+81)° and m<2=2x°.
Here ∠ 1 and ∠ 2 are adjacent angles and are supplementary ( sum to 180°), then
2x + x + 81 = 180 , that is
3x + 81 = 180 ( now subtract the number 81 from both the sides )
3x = 99 ( now divide both the sides by the number 3 )
So that, x = 33
Thus, putting the value of x in the below equations:
∠ 1 = 2x = 2 × 33 = 66°
∠ 2 = x + 81 = 33 + 81 = 114°
Hence the answer is the angle measures = ∠1 = 66°, ∠2 = 114°.

The medium-sized white-tailed deer is a native of North America, Central America, and South America as far south as Peru and Bolivia. It is often referred to as the white tail or Virginia deer.
Main body:
population of white tailed deer in 1905 = 5*10^5
population of white tailed deer in 2000 = 2*10^7
Population increase can be calculated by using simple division ,
calculating :
⇒ 2*10⁷/5*10⁵
⇒ 2*10⁽⁷⁻⁵⁾/ 5
⇒ 2*10²/ 5
⇒ 200/5

jada sells b books and m magazine subscriptions to raise money for a choir trip. She earns $4 for each book and $3 for each magazine subscription she sells, and she earns a total of $96 toward the cost of her choir trip. The equation that models the situation is 4b + 3m = 96.
[tex]b = \frac{96-3m}{4}[/tex] and [tex]m = \frac{96-4b}{3}[/tex] for the equation that models.
Jada sells b books and m magazine subscriptions to raise money for a choir trip. She earns $4 for each book and $3 for each magazine subscription she sells, and she earns a total of $96 toward the cost of her choir trip.
Given that
1. Jada sells b books and m magazines
2. She earns $4 for each book and $3 for each magazine
3. Total amount she earned is $96
Given equation is
4b + 3m = 96
Solve 4b + 3m = 96 for b
Subtract 3m from both sides
4b + 3m - 3m = 96 - 3m
4b = 96 - 3m
Now divide both sides by 4
= [tex]b = \frac{96-3m}{4}[/tex]
So, the answer for b is [tex]\frac{96-3m}{4}[/tex]
Now, solve 4b + 3m = 96 for m
Subtract 4b from both sides
4b + 3m - 4b = 96 - 4b
= 3m = 96 - 4b
Now divide both sides by 3
= [tex]m = \frac{96-4b}{3}[/tex]
So, the answer for m is [tex]\frac{96-4b}{3}[/tex]
Hence the answer is [tex]b = \frac{96-3m}{4}[/tex] and [tex]m = \frac{96-4b}{3}[/tex] for the equation that models.

b) The Standard error of p is 0.05
c) Sampling distribution of p is Normal distribution
d) E(p-hat) = 0.57 , σ(p-hat) = 0.05
Excepted value or "p-hat" is defined as the ratio of number of succes in any sample or event to the total the size of sample . It is also known as sample proportion.
P-hat = X/ N
we have given that,
Sample size (N) = 100
Probability of an event occuring (p) or population proportion = 0.57
The Excepted value of sample proportion i.e p-hat is equal to population proportion i.e p
a) so, excepted value of p = 0.57
b) Standard error of p-hat is equal to square roots of product of p and (1-p) divided by sample size .
Standard error of p- hat = √p(1-p)/n
= √0.57 × 0.43/100= 0.05
c) Sampling distribution of sample mean is normal distribution using central limit theorem.
d) Sampling distribution of p shows

Based on the data the correct interpretation of the interval is that we are 94% confident that the population mean height of college basketball players is between 65.6 and 67.1 inches. (Option B)
In statistics, a confidence interval indicates the probability that a population parameter will lie between a set of values around the population mean. It measures the degree of certainty or uncertainty in a sampling method. It is a range of values which are bounded above and below the statistic's mean that likely would contain an unknown population parameter. Confidence level is the percentage of certainty or probability of the confidence interval would include the true population parameter when a random sample is repeatedly drawn. Hence, in the given case based on the information we are 94% confident that the population mean height of college basketball players is between 65.6 and 67.1 inches.

Given that Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play. Each pair of wings is made with 3/4 yards of fabric. The fabric costs $8 per yard. The total cost of the fabric is $78.
What is the total cost?The total cost formula is used to get a total by combining the variable and fixed expenses of delivering commodities.
The step-by-step is given as follows:
1) Total cost (TC) = 3/4 (P) x 13
2) 1 pair of wings = 3/4 yard fabric
Recall that the price of 1 yard of fabric = $8

A bicycle rider rides 24 km riding at a rate greater than 8 km/ h.
Given that, a bicycle rider is riding at a rate of 15 km/h for 4/9 of his ride.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Let total number of km be x.
Distance1 =4/9 x
Distance2 =2/9 x
Remaining distance = x-(4x/9 + 2x/9)
= x-6x/9
=(9x-6x)/9
= 3x/9
Now, time =1 hour
8 = 3x/9 ÷ 1
⇒ 8×9=3x
⇒ x=24 km
Hence, a bicycle rider rides 24 km riding at a rate greater than 8 km/ h.

Find the two x intercept of the equation [tex]y=\frac{1}{2}(x+2)^2-4[/tex]
The two x intercept of the equation [tex]y=\frac{1}{2}(x+2)^2-4[/tex] is -2(√2+1) and 2(√2-1).
In the given question we have to find the two x intercept of the equation.
The give equation is [tex]y=\frac{1}{2}(x+2)^2-4[/tex].
We can find the x intercept by putting y=0. Then solving the equation for x.
Now putting y=0 in the given equation.
0= [tex]\frac{1}{2}(x+2)^2-4[/tex]
Add 4 on both side, we get
[tex]\frac{1}{2}(x+2)^2[/tex] = 4
Multiply by 2 on both side, we get
[tex](x+2)^2[/tex] = 8
Taking square root on both side, we get
x+2 = √8
x+2 = ±2√2
Subtract 2 on both side we get
x=±2√2-2
Taking 2 common
x=2(±√2-1)
Now the values of x
x={2(-√2-1), 2(√2-1)}
x={-2(√2+1), 2(√2-1)}
Hence, the two x intercept of the equation [tex]y=\frac{1}{2}(x+2)^2-4[/tex] is -2(√2+1) and 2(√2-1).

For each of the 4 stroke categories 2,4,6,8 consider a random variable representing the time of a randomly selected swimmer in that category is 0.6,0.8,0.2,0.7. What is the standard deviation of the sum of the 4 random variables?.
To calculate the Expected Value, we need to multiply each value by its probability and then sum the products up.
μ = E(x) = ∑xp(x)
That is, (0.6x2) + (0.8x4) + (0.2x6) + (0.7x8) = 1.2 + 3.2 + 1.2 + 5.6 = 11.2
Mean = 11.2
Now we take the first and second steps,
(2- 11.2)² x 0.6 = 84.64 x 0.6 = 50.78
(4 - 11.2)² x 0.8 = 51.84 x 0.8 = 41.47
(6 - 11.2)² x 0.2 = 27.04 x 0.2 = 5.4
(8 - 11.2)² x 0.7 = 10.24 x 0.7 = 7.16
Now we take the the third step and add our products together to get the variance V,
V = σ2 = ∑(x−μ)2P(x)
V = 50.78 + 41.47 + 5.4+ 7.16 = 104.81
Now we take the last step by taking the square root of the variance to get the standard deviation SD,
SD = σ = √σ2
Standard Deviation SD = √104.81 = 10.23
