KL + LM = KM
2x + 5x = 7
7x = 7
x = 7/7
x = 1
KL = 2x......2(1) = 2
LM = 5x.....5(1) = 5 <====
I think it’s 5 I’m not really sure
121 different ways. I would just simply multiply 11 songs and 11 different placements so 11 x 11 = 121
Answer:
There is a significant relation between weight and price
Step-by-step explanation:
Brand Weight(x) Price ($)
(y)
A 17.8 2100
B 16.1 6,250
C 14.9 8,370
D 15.9 6,200
E 17.2 4,000
F 13.1 8,500
G 16.2 6,000
H 17.1 2,580
I 17.6 3,500
J 14.1 8,000
Null Hypothesis :
Alternate Hypothesis :
Given : SST=51956800 SSE= 7312286.84 n = 10
SSR = SST-SSE
SSR=51956800-7312286.84
SSR=44644513.16
Level of significance =
Where m = no. of restrictions
k = No. of independent variables
F=48.843
Degree of freedom 1 = 1
Degree of freedom 2 = 10-2=8
Using calculator
p-value is .000114.
p value < α
So, we reject the null hypothesis .
Hence There is a significant relation between weight and price
Answer:
x m tall 10 m tall
--------------- = ------------
140 m shadow 4 m shadow
The height of the Stratosphere Tower is 350 m
Step-by-step explanation:
We can use proportions to solve this problem. Put the height of the object over the length of the shadow.
x m tall 10 m tall
--------------- = ------------
140 m shadow 4 m shadow
Using cross products
x*4 = 10 * 140
4x =1400
Divide by 4
4x/4 = 1400/4
x =350
The height of the Stratosphere Tower is 350 m
