This type of sampling would be Random Sampling.
Answer:
The answer is "
".
Step-by-step explanation:
Let add equation 1 and 2:
Using formula:

convert to polar coordinates


a right triangle has one angle that measures 90 degrees. that leaves 90 degrees for the other 2 angles
90 = 40 + other angle
subtract 40 from each side
50 = other angle
Answer = 50 degrees
Answer:
The number of ounce of topping that can be get is 4 .
Step-by-step explanation:
Given as :
The cost of a sundae = $3
The cost for each extra ounce of toppings = $0.50
Let The number of ounce of topping = n
The total spending cost on sundae with n extra topping = $5
Now, According to question
The total spending cost on sundae with n extra topping = The cost of a sundae + The number of ounce of topping × The cost for each extra ounce of toppings
Or , $3 + n × $0.50 = $5
or, 3 + 0.50 n = 5
or , 0.50 n = 5 - 3
or, 0.50 n = 2
∴ n = 
I.e n = 4
So, The number of ounce of topping = n = 4
Hence The number of ounce of topping that can be get is 4 . Answer
Answer:
The correct option is (d) 21.19%.
Step-by-step explanation:
Let the random variable <em>X</em> denote the heights of Fernando's peers.
The mean and standard deviation of the random variable <em>X</em> are:
<em>μ</em> = 68 inches
<em>σ</em> = 10 inches
It is provided that Fernando is 60 inches tall.
Compute the value of P (X < 60) as follows:


*Use a <em>z</em>-table.
The percentage is, 0.2119 × 100 = 21.19%.
Thus, the percentage of his peers are shorter than Fernando is 21.19%.
The correct option is (d).
