Q+B=13. When B+3=0
You have 2 separate equations.
First solve the 2nd equation for B:
B +3 = 0
Subtract 3 from both sides:
B +3 - 3 = 0-3
Simplify:
B = -3
Now we have a value for B, we can replace b with -3 in the first equation and solve for Q:
Q + -3 = 13
Add 3 to each side:
Q + -3 + 3 = 13+3
Simplify:
Q = 16
So you have Q = 16 and B = -3
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
Its just like if u have the #, 8×4-3*2+7
step 1 ; u find the grouping symbols PEMDAS ; 8×4 = 32
Rewrite ; 32-3*2+7
go to the next step ; 3 × 2 = 6
Rewrite ; 32-6+7
next ; 32 - 6 = 26
26 + 7 = 33
so 33 is your answer .
How does your figure look like?
Answer:
y=-5/4x+4
Step-by-step explanation:
as long as the slope is the same and you have a different starting point the lines will be parallel.
