Answer:
(0, 1)
(7.1, 0.49)
Step-by-step explanation:
The graph of the function is attached below.
We have an exponential function:
And we have a quadratic function:
To find the solution to:
we must look in the graph for the values of x for which both curves are intercepted, these values are:
Then the solution are the following ordered pairs:
(0, 1)
(7.1, 0.49)
Answer: when looking at the graph, anything that is going down is decreasing and anything that is going up is increasing. Maybe that can help you.
Step-by-step explanation:
Answer:
The null hypothesis can't be rejected.
Step-by-step explanation:
Given information:
Null hypothesis:
H₀ : π ≤ 0.70
Alternative hypothesis:
H₁ : π > 0.70
We need to check whether the null hypothesis is rejected or accepted.
If P-value < α, then we reject the null hypothesis H₀.
If P-value ≥ α, then we accept the null hypothesis H₀.
A sample of 100 observations revealed that p = 0.75 at the 0.05 significance level.
Here 0.75>0.05, it means p > α, therefore we can not reject the null hypothesis.
Answer:
12,690 people are expected to vote for Mr Salva
Step-by-step explanation:
Here, we want to know the number of people that is expected to vote for a particular candidate in an election given that 54% of people surveyed had said they would vote for the candidate.
Now to calculate the number of people expected to vote for Mr Salva, what we need to do is to find the number out of 23,000 that actually represents a percentage of 54%
To do this, we find 54% of 23,500
mathematically, we have;
54/100 * 23,500
= 12,690
Answer:
Step-by-step explanation
Let the number be y
y doubled = y×2=2y
2y increases by 3 = 2y+3=
2y +3 is more than 6 but less than 20
2y+3 > 6
2y+3< 20
Solve for y
2y>6-3
y>3/2
2y+3<20
2y<20-3
2y<17
y<17/2
