Answer:
40.45 cm
Step-by-step explanation:
Length of Lina's green pepper plant = 32.65 cm
It grows 2.6 cm during the months of July, August, and September.
Length at the end of July = 32.65 cm + 2.6 cm = 35.25 cm
Length at the end of August = 35.25 cm + 2.6 cm = 37.85 cm
Length at the end of September = 37.85 cm + 2.6 cm = 40.45 cm
So, its length will become 40.45 cm at the end of September.
Using the z-distribution, the 95% confidence interval for the percentage of red candies is of (7.84%, 33.18%). Since 33% is part of the interval, there is not enough evidence to conclude that the claim is wrong.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
Researching this problem on the internet, 8 out of 39 candies are red, hence the sample size and the estimate are given by:

Hence the bounds of the interval are:
As a percentage, the 95% confidence interval for the percentage of red candies is of (7.84%, 33.18%). Since 33% is part of the interval, there is not enough evidence to conclude that the claim is wrong.

Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x =
(80 - 50)° = 0.5 × 30° = 15°
Answer:I will give you an answer ,but I can't unless I can see the graph
Step-by-step explanation:
Take the GCF (-8t) of the given expression.
You'll get -8t(2t-5).
Now, set each equal to zero and solve for x.
-8t = 0 2t-5=0
t=0 t = 5/2 (Or 2.5 seconds)
