What is the area of triangle ABC?
O 3 square units
O 7 square units
O 11 square units
O 15 square units
Answers
The area of triangle ABC is 6 square units.
To find the area of triangle ABC, we need to know the lengths of its base and height.
Looking at the given diagram, we can see that the base of triangle ABC is the line segment AC, and the height is the vertical distance from point B to line AC.
From the diagram, it is clear that the base AC has a length of 3 units.
To determine the height, we need to find the perpendicular distance from point B to line AC.
By visually inspecting the diagram, we can observe that the height from point B to line AC is 4 units.
Now, we can use the formula for the area of a triangle, which is given by:
Area = (1/2) \(\times\) base \(\times\) height
Plugging in the values, we get:
Area = (1/2) \(\times\) 3 \(\times\) 4
= 6 square units
Therefore, the area of triangle ABC is 6 square units.
Based on the provided answer choices, none of the options match the calculated area of 6 square units.

To determine if their 0.500.50 inch bolts are properly adjusted, Fogarty Manufacturing has decided to use an x‾x‾-Chart which uses the range to estimate the variability in the sample. What is the Center Line of the control chart? Round your answer to three decimal places.
Answers
The center line of the x - chart is simply the average of the sample means.
Therefore, we can use 0.50 as an estimate of the center line.
The center line of the x-chart is simply the average of the sample means. Since we don't have any sample means yet, we can't calculate the center line directly.
However, we can use the specification limits to estimate the center line. If the bolts are properly adjusted, we would expect the average bolt length to be in the middle of the specification range, which is 0.50 inches. Therefore, we can use 0.50 as an estimate of the center line.
Keep in mind that this is just an estimate, and the actual center line may be higher or lower depending on the data. Once we start collecting data and calculating sample means, we can use those values to calculate the true center line.

Answers
(3.452, ∞) is the interval of t whenever the population of algae would be greater than 500.
What exactly is an equation?"It is an arithmetical statement consisting of two algebraic expressions with equal symbols."
Regarding the given question,
The equation can be used to model the quantity of algae in a bloom, P, where 't' is evaluated in weeks.
P = t⁴ + 6t³ + 7t² + 8t
We must determine the interval of t at which the population of algae will be greater than 500.
As a result, we have an inequality.
P > 500
t⁴ + 6t³ + 7t² + 8t > 500
taking 't' common.
t(t³ + 6t² + 7t + 8) > 500
This can be simplified as;
t[t(t + 6) + 7] + 8] > 500
t > 3.45 and t < - 6.759
However, time is expressed in weeks.
As a result, it will not contain values from of the interval (-∞,- 6.759).
As a result, the interval of t whenever the algae population would be higher than 500 is (3.452,∞ ).

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month?
Answers
Answer:
$840
Step-by-step explanation:
price of 1 vacuum cleaner = $150
total no . of vacuum cleaner sole = 70
thus,
price of 70 vacuum cleaner sold = 70*price of 1 vacuum cleaner
price of 70 vacuum cleaner sold = 70*$150 = $10,500
commission of Alonzo = 8% of total vacuum cleaner sold
commission of Alonzo = 8% of $10,500
commission of Alonzo = 8 /100 * $10,500 = $840
Thus, Alonzo made $840 in past month

According to the Chebyshev inequality, P(|X - 3I greaterthanorequalto 0.44) lessthanorequalto (give your answer to six decimal places)
Answers
The upper bound of the probability is P(|X - 3| ≥ 0.44) ≤ 5 / 0.44^2 ≈ 32.37e-2.
By the Chebyshev inequality, for any positive number k, we have:
P(|X - E[X]| ≥ k) ≤ Var[X] / k^2
In this case, we want to find P(|X - 3| ≥ 0.44), which is equivalent to P(X - 3 ≥ 0.44 or X - 3 ≤ -0.44). So we choose k = 0.44 and use the inequality:
P(|X - 3| ≥ 0.44) ≤ Var[X] / 0.44^2
Substituting Var[X] = 5 and solving for the upper bound of the probability, we get:
P(|X - 3| ≥ 0.44) ≤ 5 / 0.44^2 ≈ 32.37e-2
Rounding to six decimal places, we have:
P(|X - 3| ≥ 0.44) ≤ 0.323666

Answers
The absolute maximum value of f on R does not exist, while the absolute minimum value of f on R is 6.
To find the absolute maximum and minimum values of f on R, we need to consider the critical points in the interior of R and the points on the boundary of R.
First, we find the critical points by taking the partial derivatives of f with respect to x and y, and setting them equal to 0:
fx = 6x - 6 = 0, fy = 7 = 0
Solving these equations gives us the critical point (1, 0).
Next, we find the values of f at the corners of R:
f(0, 1) = 10, f(0, -1) = 22, f(2, 1) = 6, f(2, -1) = 18
Finally, we check the values of f on the boundary of R by parametrizing the boundary curve as (t, 1-t^2) for 0 ≤ t ≤ 2. Evaluating f at these points gives us a minimum value of 6 at t = 2.
Since there is no maximum value of f on R, we conclude that the absolute maximum value does not exist. The absolute minimum value of f on R is 6.

For 23: -7 * -7 * -7 = -343. This results in a negative number because there is is an odd number of negative numbers (follows the odd-even negative rule).
For 25: Multiply both sides of the equation by -1/2 to get z^3 = 216. The cube root of 216 is 6
For 26: Add 11 to both sides to get 2h^3 = 54. Divide both sides by 2 to get h^3 = 27. Cube root of 27 is 3.
