The marksman hit 54% of the targets last year when expressed as a percentage, based on hitting 27 out of 50 targets from a distance of 100 yards.
From the given information, we know that a marksman hit 27 out of 50 targets last year from a distance of 100 yards.
To analyze this data, we can calculate the hit rate or success rate of the marksman. The hit rate is calculated by dividing the number of hits by the total number of attempts or trials.
Hit rate = Number of hits / Total number of attempts
In this case, the number of hits is 27, and the total number of attempts is 50.
Hit rate = 27 / 50
Simplifying the fraction, we get:
Hit rate = 0.54 or 54%
Therefore, the marksman had a hit rate of 54% last year.
This means that out of the 50 targets attempted from a distance of 100 yards, the marksman successfully hit 27 of them.
The hit rate serves as a measure of accuracy and effectiveness in target shooting. A higher hit rate indicates a higher level of skill and precision.
It's important to note that other factors such as weather conditions, visibility, and the difficulty level of the targets can influence the hit rate. Additionally, the marksman's skills may improve or vary over time, so this hit rate represents their performance specifically for the past year.
By analyzing the hit rate, we can gain insights into the marksman's accuracy and assess their proficiency in target shooting from a distance of 100 yards.

Step-by-step explanation:
(1/2)^5 = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32
Use the law of cosines to find one angle and the law of sines to find a second angle. Then use either rule or other rules from geometry to calculate the third angle. Angles may be calculated in radians or degrees. All sides are 7.5 inches.
The value of all three angles, A , B and C is 60°
Using the cosine Rule :All sides , a,b, and c are 7.5 inches
From Cosine Rule :
CosA = (b² + c² - a²)/(2bc)
CosA = (7.5² + 7.5² - 7.5²)/(2 × 7.5 × 7.5)
CosA = 56.25/112.5
CosA = 0.5
A =
[tex] {cos}^{ - 1} (0.5) = 60[/tex]
Using Sine RuleFrom Sine Rule a/sinA = b/sinB
7.5/Sin60° = 7.5/SinB
cross multiply
7.5SinB = 7.5(Sin60°)
sinB= 6.495/7.5
SinB = 0.866
B =
[tex] {sin}^{ - 1} (0.866) = 60[/tex]
Using the Sum of Triangle RuleA + B + C = 180
60 + 60 + C = 180
C = 180 - 120
C = 60°
Therefore , all three angles A,B and C are 60° each.

The length of the variable are as follows;
x = 27.4 units
y = 12.7 units
How to find the variables in the tangent, secant and chord?When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other.
Therefore,
5(x + 5) = 6(21 + 6)
5x + 25 = 126 + 36
5x + 25 = 162
5x = 162 - 25
5x = 137
x = 137 / 5
x = 27.4 units
Let's find variable y as follows;
If a secant and a tangent are drawn to a circle from the same external point, the product of the length of the secant and its external segment equals the square of the tangent segment.
Therefore,
y² = (21 + 6)6
y² = 27 × 6
y² = 162
y = √162
y = 12.7279220614

Consider the equation below. (If an answer does not exist, enter DNE.)
f(x) = x3 − 3x2 − 9x + 3
The interval on which f(x) is increasing is (-∞, -1) and (3, ∞).
To find the interval on which the function f(x) = x³ - x² - 9x + 3 is increasing, we need to determine where the derivative of the function is positive.
First, let's find the derivative of f(x):
f'(x) = 3x² - 6x - 9
3x² - 6x - 9 = 0
3(x - 3)(x + 1) = 0
x - 3 = 0 or x + 1 = 0
x = 3 or x = -1
These are the critical points of the function.
Let's test a value from each interval:
For x < -1, let's use x = -2:
f'(-2) = 3(-2)² - 6(-2) - 9 = 12 + 12 - 9 = 15 > 0
For -1 < x < 3, let's use x = 0:
f'(0) = 3(0)² - 6(0) - 9 = -9 < 0
For x > 3, let's use x = 4:
f'(4) = 3(4)² - 6(4) - 9 = 12 - 24 - 9 = -21 < 0
From these test values, we can see that f(x) is increasing on the interval (-∞, -1) and (3, ∞).
Therefore, the interval on which f(x) is increasing is (-∞, -1) and (3, ∞).

A blood bank needs 8 people to help with a blood drive. 19 people have volunteered. Find how many different groups of 8 can be formed from the 19 volunteers.
75,582 different groups of 8 can be formed from the 19 volunteers.
In this case, we want to calculate C(19, 8), which represents the number of ways to choose 8 volunteers from a set of 19 volunteers.
The formula for combinations is given by:
C(n, r) = n! / (r!(n-r)!)
Using this formula,
C(19, 8) = 19! / (8!(19-8)!)
C(19, 8) = 19! / (8!11!)

Here are the first five terms of a number sequence. 23 20 17 14 11 (a) Write down the 8th term of this sequence. *********
The 8th term of the sequence is 2.
To find the 8th term of the given number sequence, we can observe that the sequence is decreasing by 3 with each term.
Starting from the first term, which is 23, we subtract 3 repeatedly to get the subsequent terms:
23 - 3 = 20
20 - 3 = 17
17 - 3 = 14
14 - 3 = 11
We can see that each term is obtained by subtracting 3 from the previous term.
To find the 8th term, we continue this pattern:
11 - 3 = 8
8 - 3 = 5
5 - 3 = 2
Therefore, the 8th term of the sequence is 2.

Y=x-5
x+y=-1
What is the solution to the system of equations
Answer:
x = 2
y = -3
Step-by-step explanation:
y = x - 5
x + y = -1
To solve the given system of equations, we can use the method of substitution.
That is, you can replace y with ( x - 5 ).
x + y = -1
x + (x - 5 ) = -1
x + x - 5 = -1
Combine like terms.
2x - 5 = - 1
Add 5 to both sides.
2x = - 1 + 5
2x = 4
Divide both sides by 2.
x = 2
And now let us find the value of y by replacing x with 2.
y = x - 5
y = 2 - 5
y = -3

Jack has another jar of 275 marbles that have the same distribution as the table above. Based on the information in the table, determine the number of yellow marbles
Based on the information provided in the table, Jack has 4h yellow marbles.
To determine the number of yellow marbles in the jar of 275 marbles, we can use the information from the table to find the proportion of yellow marbles in the first pouch.
According to the table, there are 4 yellow marbles out of a total of 25 marbles in the first pouch.
Therefore, the proportion of yellow marbles in the first pouch is 4/25.
To find the number of yellow marbles in the jar of 275 marbles, we can multiply this proportion by the total number of marbles in the jar.
Number of yellow marbles = (4/25) x 275 = 44
Therefore, there are 44 yellow marbles in the jar of 275 marbles.

The farmer sold 3.6 kilograms of apples at the farmers market.
To find the weight of apples the farmer sold at the farmers market, we need to subtract the weight of pears from the total weight.
We have,
3/5 of the weight is pears, the weight of pears
= (3/5) x 7.2 kilograms.
= 3.6 Kg
Since the remaining weight is apples, we can calculate the weight of apples by subtracting the weight of pears from the total weight:

The force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies
What is force of gravity?The force of gravity is the force exerted on an object by the earth or a planet.
Given that the force of gravity on an object when it is launched is 30 N/kg. This is three times larger than Earth's gravity. To determine what happens to the mass and weight of the object when gravity is 30 N/kg, we proceed as follows.
We know that weight, W = mg where
m = mass of object and g = gravitySince gravity g = 30 N/kg, we have that
W = mg
= m × 30 N/kg
= 30m
Now, we know that mass is an intrinsic property and weight is an extrinsic property. This means that the mass of the object is constant but its weight can change based on the object's position and depends on the amount of mass.
So, since the force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies
