x is another leg next to 6.
10 is the hypotenuse.
a^2 + b^2 = c^2
a & b are legs and c is the hypotenuse.
x^2 + 6^2 = 10^2
x^2 + 36 = 100
x^2 = 100 - 36
x^2 = 64
√x^2 = √64
x = 8

.Find the area of ΔABC with side lengths b = 12, c = 25, and included angle A = 17. Round your answer to the nearest tenth.
Answers
The area of the triangle with side lengths b = 12, c = 25, and included angle A = 17 is approximately 75.4 square units.
To find the area of ΔABC, with side lengths b = 12, c = 25, and included angle A = 17, we use the formula:
A = 1/2 bc sin A
where b and c are two sides of the triangle, A is the included angle between b and c, and A is measured in degrees.
In this case, b = 12, c = 25, and A = 17. Plugging these values into the formula, we get:
A = 1/2 (12)(25) sin 17° = 75.4 (rounded to the nearest tenth).
Therefore, the area of ΔABC is approximately 75.4 square units.
It is important to note that the units of area are always square units, which can be either square inches, square feet, square meters, etc. Also, rounding the answer to the nearest tenth means that we want the answer to be accurate to one decimal place.
Therefore, the area of the triangle with side lengths b = 12, c = 25, and included angle A = 17 is approximately 75.4 square units.

Answers
The critical value of t for testing the significance of each of the independent variable's coefficients will have 130 degrees of freedom.
This is because the degrees of freedom for a t-test in a regression model with 5 independent variables and 136 observations is calculated as (n - k - 1) where n is the number of observations and k is the number of independent variables.
Therefore, (136 - 5 - 1) = 130 degrees of freedom.

An engineer sketches a design for a flashlight that uses a mirror in the shape of a parabola to maximize the output of the light. The function representing the mirror is graphed on the left. Which function models the situation?
f(x) = (x – 6)2 + 2
f(x) = –(x – 0)2 + 20
f(x) = 3(x – 6)2 + 2
f(x) = –3(x – 0)2 + 20
Answers
The required quadratic function models the situation is f(x) = (1/2)(x - 6)² + 2. The correct answer would be option A.
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
The mirror is in the shape of a parabola, which is modeled by a quadratic function of form f(x) = ax² + bx + c.
Looking at the graph, we can see that the vertex of the parabola is at (6, 2) and that the parabola opens upwards. This means that the coefficient a is positive.
The function that satisfies these conditions is:
f(x) = a(x - 6)² + 2
We can rule out options B and D because they have a negative coefficient of x², which would make the parabola open downwards.
Option A has a coefficient of 1/2 for x², which would make the parabola too wide and not narrow enough to focus the light.
The correct function is therefore:
f(x) = (1/2)(x - 6)² + 2
Hence, the correct answer would be option A.

Answers
Answer:
68%
Step-by-step explanation:
In normal distribution, the empirical rule (aka 68-95-99.7 rule) describes the approximate proportion of data that falls within certain distances from the mean of a normal distribution. Specifically, the rule states that:
About 68% of the data falls within one standard deviation of the mean.About 95% of the data falls within two standard deviations of the mean.About 99.7% of the data falls within three standard deviations of the mean.an article gave the following observations on a maximum concrete pressure (kn/m^2): 33.3 41.8 37.4 40.2 36.7 39.1 36.2 41.8 36.0 35.2 36.7 38.9 35.8 35.2 40.1 using a normal probability plot, we ascertain that it is plausible that this sample was taken from a normal population distribution. calculate an upper confidence bound with confidence level 95% for the population standard deviation of maximum pressure.
Answers
A mean of a normal distribution's upper bound of a 95% confidence interval is 58.11.
What does "confidence interval" mean?This confidence interval would just be constructed using the Z or t distribution depending on the confidence level that was selected and the standard error of the point estimate.The standard error of the point estimate will be used to account for the variation in the important finding for every one of the outcome measures.For the given question,
sample mean μ = 554.4/15 = 36.96standard deviatio σ = 41.8sample size n = 15confidence interval = 95%The confidence bound's upper limit (UCB) is determined as follows:
UCB = μ + z(α/2)×σ/√n
Now, α/2 = (1 - 0.95)/2
α/2 = 0.025
z(α/2) = 1.96 (obtain from t-distribution table for degree of freedom)
Put the values in the formula,
UCB = μ + z(α/2)×σ/√n
UCB = 36.96 + 1.96×41.8/√15
UCB = 58.11
As a result, 58.11 is the upper bound of a 95% confidence interval for the mean of a normal distribution.

You roll a fair die 6 times. (a) What is the probability that you roll at least one 6? (b) What is the probability of rolling 5 different numbers?
Answers
(a) The probability of rolling at least one 6 is approximately 0.665, or about 66.5%.
(b) The probability of rolling 5 different numbers is approximately 0.0772, or about 7.72%.
(a) To calculate the probability of rolling at least one 6 in 6 rolls of a fair die, we can use the complement rule: the probability of the complement (rolling no 6s) is easier to calculate, and then we subtract that from 1.
The probability of rolling no 6s in a single roll is 5/6, so the probability of rolling no 6s in 6 rolls is (5/6)^6.
Therefore, probability of rolling at least one 6 in 6 rolls is:
1 - (5/6)^6 ≈ 0.665
So the probability of rolling at least one 6 is approximately 0.665, or about 66.5%.
(b) To calculate the probability of rolling 5 different numbers in 6 rolls of a die, we can use the formula for combinations. There are 6 possible numbers that could be rolled first, 5 possible numbers that could be rolled second (since we want 5 different numbers), and so on down to 2 possible numbers that could be rolled fifth.
For the sixth roll, any of the 5 previous numbers would result in 5 different numbers, so there are 5 choices. Therefore, the total number of ways to roll 5 different numbers is:
6 × 5 × 4 × 3 × 2 × 5 = 3600
To find the probability, we divide this by the total number of possible outcomes for rolling a die 6 times, which is 6^6 = 46656. Therefore, the probability of rolling 5 different numbers in 6 rolls of a die is:
3600/46656 ≈ 0.0772
So the probability of rolling 5 different numbers is approximately 0.0772, or about 7.72%.

is the width of the TV?
A) 400 inches
B) 40 inches
C) 20 inches D) 29.2 inches
Answers
Answer: 20 inches
Step-by-step explanation:
From the question, a television screen has a length of 15 inches while the diagonal of the TV is 25 inches. To calculate the width, we will use the hypoteneous rule.
Hypotenuse² = length² + width²
25² = 15² + width²
width² = 25² - 15²
width² = 625 - 225
width² = 400
width = ✓400
width = 20
The width of the TV is 20 inches.

water leaking onto a floor forms a circular pool. the radius of the pool increases at a rate of 6 cm /min. how fast is the area of the pool increasing when the radius if is 10 cm?
Answers
When the radius is 10 cm, the area of the pool is increasing at a rate of 120π cm^2/min.
To find how fast the area of the pool is increasing, we can use the formula for the area of a circle, A = πr^2, where A represents the area and r represents the radius.
Given that the radius is increasing at a rate of 6 cm/min, we can express this as dr/dt = 6 cm/min.
We want to find dA/dt, the rate of change of the area with respect to time. To do this, we can differentiate both sides of the equation A = πr^2 with respect to time:
dA/dt = d/dt (πr^2)
Using the chain rule, we have:
dA/dt = 2πr (dr/dt)
Substituting the given values, when r = 10 cm and dr/dt = 6 cm/min, we can calculate the rate of change of the area:
dA/dt = 2π(10)(6) = 120π cm^2/min
