Answer:
3, 4, and 5 make a right triangle (Pythagorean triple). 3 and 4 are the legs, 5 is the hypotenuse. Another example is 9, 12, 15, with 9 & 12 as the legs and 15 as the hypotenuse on a right triangle.
Step-by-step explanation:
Pythagorean triples (measurements are whole numbers) are always in a 3:4:5 ratio; the longest side is always hypotenuse; the right angle is always opposite of the hypotenuse; the legs will be perpendicular (making right angle)

−4≤t≤5minus, 4, is less than or equal to, t, is less than or equal to, 5?
The average rate of change over is 1.
Given that;
the function is,
⇒ g (t) = - (t - 1)² + 5
Hence, We need to determine the average rate of change over the interval - 4 ≤ t ≤ 5.
The value of G(-4):
The value of G(-4) can be determined by substituting t = -4 in the function
⇒ g (t) = - (t - 1)² + 5
Thus, we have,
⇒ g (t) = - (-4 - 1)² + 5
⇒ g (t) = - 20
Thus, the value of G(-4) = -20
The value of G(5):
The value of G(5) can be determined by substituting t = 5 in the function , we get,
⇒ g (t) = - (t - 1)² + 5
⇒ g (t) = - (5 - 1)² + 5
⇒ g (t) = - 11
Thus, the value of G(5) is, -11
Now, Average rate of change:
The average rate of change can be determined using the formula,
⇒ G(b) - G (a) / (b - a)
where, a = - 4 and b = 5
Substituting the values, we get,
⇒ G(5) - G (-4) / (5 - (-4))
⇒ ( - 11 - (- 20)) / 9
⇒ 9/9
⇒ 1
Thus, the average rate of change over the interval is. 1.

An urn contains nine blue balls and seven yellow balls. If three balls are selected randomly without being replaced, what is the probability that of the balls selected, one of them will be blue and two of them will be yellow?
Answer:
\(Probability = \frac{27}{80}\)
Step-by-step explanation:
Given
\(Blue =9\)
\(Yellow = 7\)
Required
Determine the probability that one of the balls is blue while others is yellow
The order of selection may be any of these three:
Yellow, Yellow, Blue or Yellow, Blue, Yellow or Blue, Yellow, Yellow
Solving Yellow, Yellow, Blue
\(Probability = P(Y_1) * P(Y_2) * P(B)\)
\(Probability = \frac{7}{16} * \frac{6}{15} * \frac{9}{14}\)
\(Probability = \frac{1}{8} * \frac{1}{5} * \frac{9}{2}\)
\(Probability = \frac{9}{80}\)
Solving Yellow, Blue, Yellow
\(Probability = P(Y_1) * P(B) * P(Y_2)\)
\(Probability = \frac{7}{16} * \frac{9}{15} * \frac{6}{14}\)
\(Probability = \frac{9}{80}\)
Solving Blue, Yellow, Yellow
\(Probability = P(B) *P(Y_1) * P(Y_2)\)
\(Probability = \frac{9}{16} * \frac{7}{15} * \frac{6}{14}\)
\(Probability = \frac{9}{80}\)
Hence:
The required probability is:
\(Probability = \frac{9}{80} + \frac{9}{80} + \frac{9}{80}\)
\(Probability = \frac{27}{80}\)

v = 0u = 5h = -7 n = 2 x = 8 r = 7Step-by-step explanation:
1) 4v + 7 = 7, for v?
→ 4v + 7 = 7
→ 4v = 7 - 7
→ v = 0/4
→ [ v = 0 ]
2) 3(u + 4) = 27, for u?
→ 3(u + 4) = 27
→ 3u + 12 = 27
→ 3u = 27 - 12
→ u = 15/3
→ [ u = 5 ]
3) -20 = 10(h + 5), for h?
→ -20 = 10(h + 5)

→ [ h = -7 ]
4) -10 = (n - 52)/5, for n?

→ [ x = 8 ]
6) 8r = 2r + 42, for r?
→ 8r = 2r + 42
→ 8r - 2r = 42

The volume of a rectangular prism is 5,890.625 cm3. If the height is 14.5 cm and the length is 25 cm, what is the value of the width?
Answer:
Step-by-step explanation:
The formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
We know that V = 5,890.625 cm^3, h = 14.5 cm, and l = 25 cm.
Substituting these values into the formula, we get:
5,890.625 = 25w(14.5)
5,890.625 = 362.5w
w = 16.25
Therefore, the width of the rectangular prism is 16.25 cm.
Answer:
It's A

What is a line segment ?
A line segment in geometry is bounded by two separate points on a line. Another way to describe a line segment is as a piece of the line that joins two points. A line segment has two fixed or distinct endpoints while a line has no endpoints and can stretch in both directions indefinitely.
For sapling 1 = No distance is covered.
For sapling 2, distance covered = 10 m
Return distance=10 m
For sapling 3, distance covered =20 m
Return distance=20 m and so on
Thus the distances covered for saplings can be represented as : 0,2(10), 2(20),...i.e. 0,20, 40,...
Therefore total distance covered by Jeremy for planting 12 saplings and coming back to original position = S 12

The z-scores of the monthly utility bills for the value of x as $60, $71 and $9 are -1.25, 0.125, and 2.25 respectively.
What is Z-score?
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Z = (X - μ)/σ
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
As it is given that the standard deviation of the monthly utility bills is $8, while the mean is $70. Therefore, the z-score can be written as,
A.) X= 60
z= (60- 70 )/8 = -1.25
B.) X = 71
z = ( 71 -70)/8 = 0.125
C.) X = 92
z= (92 - 70)/8 = 2.25
Hence, the z-scores of the monthly utility bills for the value of x as $60, $71 and $9 are -1.25, 0.125, and 2.25 respectively.

Step-by-step explanation:
Triangle ABC is similar to triangle FGH. Given the following angle measures, find the missing angle measures.
m∠A = 22 degrees
m∠B = 75 degrees
m∠F = _____ degrees
m∠G = _____ degrees
m∠H = _____ degrees
m∠C = _____ degrees
Answer:
Since triangle ABC is similar to triangle FGH, their angle measures are proportional. We can use the ratios of their angle measures to find the missing angle measures.
Let's call the missing angle measures x, y, z, and w, where x is m∠F, y is m∠G, z is m∠H, and w is m∠C.
From the given information, we have:
m∠A / m∠F = 22 / x
m∠B / m∠G = 75 / y
Since m∠A + m∠B + m∠C = 180 degrees, we can write:
w = 180 - (m∠A + m∠B)
m∠H / m∠C = z / w
Now we can use the ratios to find the missing angle measures:
x = 22 / (22 / x) = 22
y = 75 / (75 / y) = 75
z = m∠H / (m∠H / z) = m∠H
w = 180 - (22 + 75) = 83
So, the missing angle measures are:
m∠F = 22 degrees
m∠G = 75 degrees
m∠H = m∠H (unknown)
m∠C = 83 degrees

Now, in this histogram given, we see that the y-axis is for the relative frequency, while the x-axis is the Response time (in seconds).
Observing this histogram closely, it is clear that the response times are all symmetrical around the interval 50 - 60 seconds as it is also the middle element of the histogram.

After sampling 121 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.21 cm. He knows that the population standard deviation is 0.83 cm. Assuming a level of significance of 0.02, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines? Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
The sample mean of 4.21 cm is significantly different from the specified target mean of 4.00 cm.
Step 1: State the hypotheses.
- Null Hypothesis (H₀): The mean length of the bolts is 4.00 cm (μ = 4.00).
- Alternative Hypothesis (H₁): The mean length of the bolts is not equal to 4.00 cm (μ ≠ 4.00).
Step 2: Compute the value of the test statistic.
To compute the test statistic, we will use the z-test since the population standard deviation (σ) is known, and the sample size (n) is large (n = 121).
The formula for the z-test statistic is:
z = (X- μ) / (σ / √n)
Where:
X is the sample mean (4.21 cm),
μ is the population mean (4.00 cm),
σ is the population standard deviation (0.83 cm), and
n is the sample size (121).
Plugging in the values, we get:
z = (4.21 - 4.00) / (0.83 / √121)
z = 0.21 / (0.83 / 11)
z = 0.21 / 0.0753
z ≈ 2.79 (rounded to two decimal places)
Step 3: Determine the critical value and make a decision.
With a level of significance of 0.02, we perform a two-tailed test. Since we want to determine if the mean length of the bolts is different from 4.00 cm, we will reject the null hypothesis if the test statistic falls in either tail beyond the critical values.
For a significance level of 0.02, the critical value is approximately ±2.58 (obtained from the z-table).
Since the calculated test statistic (2.79) is greater than the critical value (2.58), we reject the null hypothesis.
Conclusion:
Based on the computed test statistic, there is sufficient evidence to show that the manufacturer needs to recalibrate the machines. The sample mean of 4.21 cm is significantly different from the specified target mean of 4.00 cm, indicating that the machine's output is not meeting the desired length. The manufacturer should take action to recalibrate the machines to ensure the bolts meet the required length of 4.00 cm.
