Let's write T for Teagan's score and E for Emma's score.
Also, let's write an equation
E = 2T + 4
E = 3
2T + 4 = 3
subtract 4 from both sides
2T = -1
divide both sides by 2
T = -1/2
To see of this is correct:
2T + 4 = 3
2(-1/2) + 4 =?= 3
-1 + 4 =?= 3
3 = 3
Hope this helps
Answer:
C. x=3
Step-by-step explanation:
Because the sides are proportionate to each other
Side 3 is 3x the length of Side 1
Therefore,
Side 9 is also 3x the length of side X
3x=9
Divide both by 3
and X will be 3.
Xy = 6
x = 2
2y = 6
y = 6÷2
y = 3
x + y = (2) + (3) = 5
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Sample mean : hours
Standard deviation hours
Sample size : n=90, which is a large sample(n<30), so we use z-test.
Significance level:
Critical value :
Then , the confidence interval for population mean will be :-
Hence, the 90% confidence interval for the mean life of all light bulbs of this type. is
