Answer:
the first four terms are 2, 4, 6, and 8
Step-by-step explanation:
the y intercept becomes the first term. the for each value y increases by 2, this is the common difference.there are two ways you can get it. the by using equation of linear graphs y=mx+c and another by using the formula of AP Tn=a+(n-1)d.
both m(slope) and common difference(d) means the same thing.
Answer:
x = 10
BD = 74
Step-by-step explanation:
Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.
Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.
Answer:
u= -7
Step-by-step explanation:
<h2><u>
Answer with explanation</u>
:</h2>
Let p be the population proportion of parents who had children in grades K-12 were satisfied with the quality of education the students receive.
Set of hypothesis :

Confidence interval for population proportion is given by :-
, where
n= sample size
= sample proportion
and
is the two-tailed z-value for confidence level (c).
As per given ,
Sample size of parents : n= 1085
Number of parents indicated that they were satisfied= 466
Sample proportion : 
Critical value for 90% confidence interval :
( by z-value table)
Now, the 90% confidence interval :
Thus , the 90% confidence interval: (0.4043, 0.4537).
Since 0.43 lies in 90% confidence interval , it means we do not have enough evidence to reject the null hypothesis .
i.e. We are have no evidence that parents' attitudes toward the quality of education have changed.
The expression would be: 11.5-1 1/2x
x represents the number of weeks she would cut her hair off.
