Answer:
x = 20.5
Step-by-step explanation:
Since you are given the hypotenuse and the adjacent side to 70 then you have the cos 70 = adj/hyp so cos 70 = 7/x so x = 7/cos 70, so x = 20.467
Samuel pays $8.34
a way you can figure this out is:
3 times 4 plus 3 and your answer comes out to 15
then: 15 divided by 4 and that equals 3.75
now: 3.75 times $2.25
Answer:
Increase by 5% ;
Remain unchanged
Step-by-step explanation:
Given that:
Raise received by all workers = 5%
Since the raise in salary cuts across all employees, then the average or mean salary will also increase by the same amount.
y = m ± c
y = new mean ; m = initial mean ; c = increase
The standard deviation on the other hand isn't affected due to change in a constant value. That is the standard deviation of a. Constant value is Zero. Hence, the standard deviation remains unchanged.
