Answer:
3a+7=5a-3
5a-3a=3+7
2a=10
a=5
Again
6b-5=2b+9
6b-2b=5+9
4b=14
b=14/4=7/2
Step-by-step explanation:
Answer:
we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
Step-by-step explanation:
Given data
n=29
mean of x = 49.98 mm
S = 0.14 mm
μ = 50.00 mm
Cl = 95%
to find out
Can we be 95% confident that machine calibrated properly
solution
we know from t table
t at 95% and n -1 = 29-1 = 28 is 2.048
so now
Now for 95% CI for mean is
(x - 2.048 × S/√n , x + 2.048 × S/√n )
(49.98 - 2.048 × 0.14/√29 , 49.98 + 2.048 × 0.14/√29 )
( 49.926757 , 50.033243 )
hence we say for μ = 50.00 mm we be 95% confident that machine calibrated properly with ( 49.926757 , 50.033243 )
Let, the numbers are: x, y
So, Equations will be: x - y = 22
x = 2y + 9
Substitute the value of x in first equation,
2y + 9 - y = 22
y = 22 - 9
y = 13
x - 13 = 22
x = 22 + 13 = 35
In short, Larger number would be 35
Hope this helps!
Answer:
slope = 3/1 or just 3
y intercept = (0, 5)
Step-by-step explanation:
Answer:
TRUE
Step-by-step explanation:
TRUE
a_1 = 2
a_n = 2*(an_1)
if we start with 2, we would get
a_2 = 2*(a_1) = 2*(2) = 4
a_3 = 2*(a_2) = 2*(4) = 8
a_4 = 2*(a_3) = 2*(8) = 16
a_5 = 2*(a_4) = 2*(16) = 32
