Answer:
1) null: π = 0.5, alternative: π > 0.5
2)p^= 80/124 =0.645
std error =(phat(1-phat)/n)1/2 =0.0430
3)z = (phat-p)/std erro =(0.645-0.5)/0.0430 =3.22
4)The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations above the null hypothesized value of 0.50
5)We have strong evidence that the proportion of couples that lean their heads to the right while kissing is more than 50%
Answer:
+5 or -5.
Step-by-step explanation:
Given equation,
5x-10/x^2-25
When you divide something with zero, it becomes undefined. So, to be undefined, x will have to be that value which makes the divisor zero.
Now, x^2-25= 0
Or, x^2= 25
Or, x= +5,-5.
So, for the value +5 and -5, the divisor becomes zero and makes the whole equation undefined.
Answer:
See answer below
Step-by-step explanation:
y = one time fee
35x = hourly rate( hours worked)
35x + y = $190
y = - 35x = 190
$35 per hours × hours work and you did not used the total cost $190
Next time rewrite the sentence and translate into an equation.
The customers service charges = one-time fee + hourly rate$ ( hours worked)
190 = y + 35(x) point slope form
- 35x + 190 = y
Given is an A.P. in which -
- First term,a = 2
- Common difference = Second term - First term
<h3><u>Solution:- </u></h3>
nth term of an A.P ,is given by-
where
- a = first term
- n = number of term
- d = common difference
Putting n = 46
Therefore, the 46th term is 227
