Answer: i took the test and got it right
D (0.55,0.75)
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
The slopes are not opposite and they are not equal either
line up 2x+3y=42 and -3x +2y=16
2x+3y=42=-3x+2y=16
get each term on one side and isolate.
If this is not possible, you have your answer. Another way to do this is graphing it and seeing if the two lines intersect, and if they do, if they make a right angle
Answer:
0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean = 
a) 
: N(78, 4)
b) 
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
Answer:
b= -3
x= -2
x= -7
n = -6
Step-by-step explanation:
3b+7-1=-3
3b = -3 -7 +1
3b = -10+1
3b= -9
b = -9/3
b= -3
3x+1-6x=7
-3x = 7-1
-3x= 6
x= -6/3
x= -2
312=-6(7x-3)
312 = -6*7x +6*3
312= -42x +18
312-18= -42x
294 = -42x
x= -294/42
x= -7
-4(4n-8)=128
-4*4n +4*8 =128
-16n +32 = 128
-16n= 128-32
-16n = 96
n=-96/16
n = -6
Answer:
$960.24
Step-by-step explanation:
Hello!
Let the regular price be x.
38% of x = 0.38x
0.38x = 364.89
<h3>Solve for x</h3>
- 0.38x = 364.89
- x = 364.89/0.38
- x = 960.2368421053 ≈ 960.24
The price of the table yesterday was around $960.24.
