$269.15 discount 499.85 sales price
Step-by-step explanation:
If the price is $769 it's off 35% you turn the percent into a decimal which is .35 then you multiply it by the price of $769. You then get $269.15 for the discount price and then you subtract the regular price $769 from the discount price which is $269.15. So you get $499.85 as your answer
Answer: The goodness-of fit chi square test
Step-by-step explanation:
The areas of the square pyramid are the amount of space on it
- The lateral surface area is 292.5 square cm
- The total surface area is 354.85 square cm
<h3>How to determine the lateral surface area?</h3>
The given parameters are:
Base (b) = 15 cm
Slant height (l) = 13 cm
The lateral surface area is calculated using:
L = 1.5bl
So, we have:
L = 1.5 * 15 * 13
Evaluate the product
L = 292.5
<h3>How to determine the total surface area?</h3>
This is calculated using:
T = L + 0.25√3b^2
So, we have:
T = 292.5 + 0.25√3 * 12^2
Evaluate
T = 354.85
Hence, the total surface area is 354.85 square cm

By using the definition of <em>second order</em> polynomials and the discriminant from <em>quadratic</em> formula, we conclude that the values of k must be less than 1/4.
<h3>How to determine the value of k such that a line intersects a quadratic equation</h3>
In this question we must determine the set of values of k such that the function g(x), a <em>linear</em> function, intersects a<em> quadratic</em> function f(x) at two points. In this case, we must solve the following <em>second order</em> polynomial:
k · x² + 4 · x - 3 - g(x) = 0
k · x² + 4 · x - 3 - 2 · x + 7 = 0
k · x² + 2 · x + 4 = 0
In this case, the discriminant of the equation described above must be <em>positive</em>:
2² - 4 · k · 4 > 0
4 - 16 · k > 0
4 > 16 · k
16 · k < 4
k < 1/4
By using the definition of <em>second order</em> polynomials and the discriminant from <em>quadratic</em> formula, we conclude that the values of k must be less than 1/4.
