Answer:did you ever find the answer?
Step-by-step explanation:
Hints:
1) This is an arithmetic sequence.
2) The first member of the sequence is 4.
3) The common difference is 6. To each member, we add 6 to get the next.
4) The formula for the nth term of an arith. sequence is as follows:
l=a + (n-1)d, where l is the LAST term, n is the number of terms, d is the common difference, and a is the first term. Write this out. Play with n, increasing (integer) n until this formula predicts numbers close to 576. Do you get exactly 576 for one of these INTEGER n values? If yes, then 576 is a member of the sequence. If no, then it is not.
The sum of opposite pair of a quadrilateral is 180°
so ∠DAB +∠DCB=180
We are given ∠DCB=122°
122° +∠DAB =180°
∠DAB =180°-122°= 58°
Answer : ∠DAB =58°
Answer:
Option A is correct
Step-by-step explanation:
Given is a table which shows data from a survey about the amount of time students spend doing homework each week.
College HS
High 50 16
Low 5 0
Q1 7.5 9.5
Q3 15 14.5
IQR 7.5 5
Median 11 13
Mean 13.8 10.7
Std dev 6.4 5.3
1.5IQR 11.25 7.5
Q1-1.5IQR -9.38 -12
Q3+1.5IQR 37.5 29.5
WE find that there is only one outlier in college with 50 as high.
Except that all others are well within IQR range. Hence outliers are minimum
So option A is right.
Answer:
y = 3/2 * x + 12
Step-by-step explanati
2x + 3y = 12
y = -2/3x + 4
slope: -2/3
slope' of perpendicular line: 3/2
6 = 3/2 * (-4) + b
b = 12
equation: y = 3/2 * x + 12
