Answer:
(2,8)
Step-by-step explanation:
Answer:
The probability is 0.000495
Step-by-step explanation:
As per the question:
Total no. of cards in a deck = 52
No. of spades in a deck = 13
Now, we have to select 5 cards in a deck such that they belong to the same suit, i.e., spades.
The no. of ways of selecting 5 cards from a deck = 
The no. of ways of selecting 5 cards from 13 spade cards = 
Now,
Probability that the selected 5 cards are all spades, P(E) = 
P(E) = 
P(E) = 
P(E) = 
P(E) = 
Answer:
C. 25 ÷ 10
Step-by-step explanation:
A. 10/25
B. 2/5
C. 25 ÷ 10
D. 0.4
Total customers at Becky's restaurant = 25
Customers who order wheat rolls = 10
It means 10 out of 25 customers order wheat rolls
That is
10 / 25
Dividing both numerator and denominator by 5
= 2 / 5
2/5 in decimal
= 0.4
The option Which does NOT represent the part of the customers who order wheat rolls
is 25/10
Option C. 25 ÷ 10
The answer to the problem is as follows:
x = sin(t/2)
<span>y = cos(t/2) </span>
<span>Square both equations and add to eliminate the parameter t: </span>
<span>x^2 + y^2 = sin^2(t/2) + cos^2(t/2) = 1 </span>
<span>The final step is translating the original parameter limits into limits on x and y. Over the -Pi to +Pi range of t, x varies from -1 to +1, whereas y varies from 0 to 1. Thus we have the semicircle in quadrants I and II: y >= 0.</span>
