The quadratic formula helps us solve any quadratic equation. First, we bring the equation to form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
This is proven and I’m positive this is what your asking! BRAINLIEST please
Answer:
(A) We failed to reject the null hypothesis
Step-by-step explanation:
Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:
Here p value is 0.34
This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.
Whenever p > alpha, we fail to reject null hypothesis
A) We failed to reject the null hypothesis
This would be the correct option
i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.
First,you should graph<span> the equals line, then lightly shade in the correct area. 3 steps: Rearrange the equation so "y" is on the left and everything else on the right. or below the line for a "less than" (y< or y≤)</span>
Answer:
We have, 15% × x = 85
or,
15
100
× x = 85
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 85 ×
100
15
x = 566.67
