Divide both sides by 5
e^x=3.152 take the natural log of both sides...
x=ln(3.152)
x≈1.148
Considering the situation described, the scientist's null and alternative hypothesis are described by:
Null hypothesis
; Alternative hypothesis
.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by
is of 0, hence:
![H_0: \mu = 0](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu%20%3D%200)
At the alternative hypothesis, it is tested if there is a difference, hence:
![H_1: \mu \neq 0](https://tex.z-dn.net/?f=H_1%3A%20%5Cmu%20%5Cneq%200)

Answer:
Step-by-step explanation:
i can help
Step 1
-(x + 8) = -x Simplify
Step 2
-(x + 8) = -x Simplify the sides of the equation
-x-8=-x
Step 3
-x-8=-x Add x to the sides
-8=0
Step 4
-8=0 Add 8 to the sides
0=8
Answer
No solution

Answer:
a)
Step-by-step explanation:
hello,
because of the end behaviour the constant in
should be positive so we have a) or d)
f(0)=-3 in both cases
for A) f(x)=
![x^2-3=(x-\sqrt{3})(x+\sqrt{3})](https://tex.z-dn.net/?f=x%5E2-3%3D%28x-%5Csqrt%7B3%7D%29%28x%2B%5Csqrt%7B3%7D%29)
so f(x)=0 for ![x=\sqrt{3} \ or \ x = -\sqrt{3}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B3%7D%20%5C%20or%20%5C%20%20x%20%3D%20-%5Csqrt%7B3%7D)
so the correct answer is A)
hope this helps
