Answer:
D, E
Step-by-step explanation:
In the table, r = 3p, and by converse, p = 1/3r. These options are D and E
P = 2(L + W)
P = 22
L = 2W + 2
22 = 2(2W + 2 + W)
22 = 2(3W + 2)
22 = 6W + 4
22 - 4 = 6W
18 = 6W
18/6 = W
3 = W.....this is the width
L = 2W + 2
L = 2(3) + 2
L = 6 + 2
L = 8 meters <=== this is the length
Answer:
46°
Step-by-step explanation:
BE is the bisector so abe is the same as ebc
2x+20=4x-6
26=2x
13=x
so now plug x back into abe to find its measure
2(13)+20
26+20
46
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Answer:
y = 10x + 100
Step-by-step explanation:
Given the information:
She earns the same amount per hour as she did in her old job $ 100 sign-on bonus
=> the equation for line p in the form y= mx where:
- x is the number of hour she worked
=> the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )
From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q
We can create two points (0, 0) and (2, 20) are on line p
<=> m = 
The equation for line p is y = 10x
=>The equation for line q should include the hourly earnings at the
new job plus the sign-on bonus. The equation is y = 10x + 100
Hope it will find you well.
