Answer:
See explaination and attachment
Step-by-step explanation:
Given the parameters we have, we want to Construct a 90% confidence interval for the true mean of the population.
Hence, making use of these parameters;
sample size =100
Std deviation =25
mean if the sample=253.
Therefore solving for 90% confidence interval for the true mean of the population. We will apply a formula.
Please kindly check attachment gor the step by step solution for all the questions.
Answer:
(x)^2+ (y+2)^2 = 49
Step-by-step explanation:
The standard form of a circle is
(x-h)^2+ (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-0)^2+ (y--2)^2 = 7^2
(x)^2+ (y+2)^2 = 49
this is just a example
lmk if u get it
Step-by-step explanation:
The "new" square must have sides of size 8
8 * 8 = 64
so the original square must have had sides of size 5cm. 8 - 3
- (1 + 7x) - 6(- 7 - x) = 36
- 1 - 7x + 42 + 6x = 36
41 - x = 36
- x = - 5
x = 5
I don’t understand this either ask the teacher
