Answer:
d) neither
Step-by-step explanation:
Given equation is 7x - 5 = 4y -6 ...…...... (1)
Substitute x = 2 and y= 4 in equation (1)
7(2) -5 = 4(4) -6
9 ≠ 10
a) is not satisfied
Substitute x = 3 and y= 6 in equation (1)
7(3) -5 = 4(6) -6
16 ≠ 18
b) is not satisfied
c) is also not satisfied
<u>Final answer</u>:- neither

Hello,
sin (30°)= cos (60°)=1/2 (complementary angles)
sin D= cos E
Answer C
To evaluate the <span>probability that in a randomly selected hour the number of watches produced is greater than 500 we proceed as follows:
z=(x-</span>μ<span>)/</span>σ
where:
x=500
μ=500
σ=100
thus
z=(500-500)/200=0
Thus:
P(x>500)=1-P(x<500)=1-P(z<0)=1-0.5=0.5
Answer: 0.5~50%
