Answer:
angle WSV = 37°
Step-by-step explanation:
Angle RSU and Angle VST are verticle angles, which means they have the same measure.
Angle VST = 53°
Since SW is perpendicular to RT, that means angle WST is a right angle (90°).
Subtract angle VST from 90°.
90 - 53 = 37°
angle WSV = 37°
Answer: not a solution
Step-by-step explanation: 7a = 7 * 21 which does not equal 28, it equals 147, 7 * 4= 28, so actually a=4
Hope this helps :)
Answer:
pls kindly provide the following theorems
Answer:
c. normal probability distribution
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
In this question:
By the Central Limit Theorem, it is a normal distribution, so option c.
The question follows the special product rule of polynomials.
(a-b)(a+b) = a^2 - b^2
From the given, (3-2i)(3+2i), then the answer will be 3^2 - (2i)^2
simplifying the answer:
9 - 4i^2
Take note that i = square root of -1
Then, i^2 = -1
So, 9 - (4 * -1)
= 9 - -4
= 13.
So the answer is 13.
