Answer:
Mr. Hildebrant planned to spend $95 in the gift shop.
Step-by-step explanation:
We want to find 80% of $? equals $76.
We can write an equation to help us solve for <u>x</u>, <u>the money that Mr. Hildebrant planned to spend in the gift shop</u>.
Divide both sides of the equation by .80.
Mr. Hildebrant planned to spend $95 in the gift shop.
The estimation goal is to estimate a population parameter. The estimation process uses sample statistics.
<h3>What is the goal of hypothesis testing?</h3>
The goal of hypothesis testing is testing to claim whether it is right or wrong.
The hypothesis testing also uses statistics to determine whether or not a treatment has an effect.
<h3>What is the goal of estimation?</h3>
The estimation goal is to estimate a population parameter. The estimation is used to determine how much effect a treatment has.
To estimate a parameter, a sample statistics of the parameter is used.
Thus, the estimation is to estimate a population parameter.

If you are asking what this is the definition of, i think it's the domain, although i couldn't say this is all the way correct,because that's in relation tho input-output function
Answer: (no real solutions) but if its complex math it's:
x= 0.0000 + 5.0000
x= 0.0000 - 5.0000
Step-by-step explanation: Solve : x2+25 = 0
Subtract 25 from both sides of the equation :
x2 = -25
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ -25
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Accordingly, √ -25 =
√ -1• 25 =
√ -1 •√ 25 =
i • √ 25
Can √ 25 be simplified ?
Yes! The prime factorization of 25 is
5•5
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 25 = √ 5•5 =
± 5 • √ 1 =
± 5
The equation has no real solutions. It has 2 imaginary, or complex solutions.
Answer:
y= -x-5
Step-by-step explanation:
m=1-(-5)/-4-2
m=-1
-1= -x
y=-x-5
