Answer:
15.75
36
15.75
Step-by-step explanation:
Formula
the relationship between these two secants is NQ * NP = NM * LM
Givens
- NP = 32
- NQ = x
- NM = 14
- NL = 14 + 22 = 36
Solution
x*32 = 14*36 Substitute values. Divide by 32
x = 14 * 36/32 Multiply 14 and 36
x = 504/32 Divide by 32
x = 15.75
The answer to the first box is 15.75 or x
The answer to the second box is
LM is assumed to be 22 So LN = MN + LM = 22 + 14= 36
QN = 15.75 is the third answer.
Answer:
4x 3 - 6 4 is the answer

Answer:
50,27
Step-by-step explanation:
let the parts be x and y
x+y=77
x=2y-4
substitute
2y-4+y=77
3y=77+4
3y=81
y=81/3=27
x=2×27-4=54-4=50
First, you must use ADDITION to find -12 + 8 (-4)
Then, use MULTIPLICATION to find -4*2 (16
1) Addition
2) Multiplication
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 )
