To convert decimal over to percent, we move the decimal place two places to the right. So 0.5 becomes 50%.
You just need to divide 13 and 2 and get 6.5.
Answer should be 4
Explanation: 30 divided by 8 = 3.75
3.75 rounded is 4
To determine the probability that there will be no women, you need to find the probability of women and subtract it from the total
60 - 10 = 50
so you find the probability with the total number of people being 50, that way the women's probability is eliminated.
5 out of 50 multiplied by the original total of the people, 60
(5÷50)×60 = 6
Therefore the probability of randomly choosing 5 people, excluding women is 6
Answer:
(2, - 1 ) and (5, 2 )
Step-by-step explanation:
y + 2 = (x - 3)² → (1)
y + 3 = x ( subtract 3 from both sides )
y = x - 3 → (2)
Substitute y = x - 3 into (1)
x - 3 + 2 = (x - 3)² ← expand using FOIL
x - 1 = x² - 6x + 9 ( subtract x - 1 from both sides )
0 = x² - 7x + 10 ← in standard form
0 = (x - 2)(x - 5) ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
Substitute these values into (2) for corresponding values of y
x = 2 : y = 2 - 3 = - 1 ⇒ (2, - 1 )
x = 5 : y = 5 - 3 = 2 ⇒ (5, 2 )
