Answer:
2.60
Step-by-step explanation:
z-score is the difference between the score and mean, divided by the standard deviation.


So 2.6 is an answer close enough.
y = 3
x = -2
These are the solutions after elimination
Answer:
1 - 1/3 - 1/4 - 1/5
Step-by-step explanation:
Let's take it one step at a time.
Day 1 he completes 1/3 of the garage, so you subtract 1/3 from 1 which means he left 2/3
Day 2 he completed 1/4 more, so you again subtract, this time though 2/3 - 1/4, or in other words 1 - 1/3 - 1/4
So you do this one more time. 1 - 1/3 - 1/4 - 1/5
Can you handle this or do you need help with fraction subtraction.
Answer:
The correct answer is option C. Cos x
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see that, a right triangle with angles and sides are given.
<u>To check the options</u>
1) Sin x = Opposite side/Hypotenuse = p/q
2). Cos y = Adjacent side/Hypotenuse =p/q
3). cos x= Adjacent side/Hypotenuse = r/q
4). tan y = Opposite side/Adjacent side = r/p
Therefore the correct answer is option C. Cos x
