Answer:
5
Step-by-step explanation:
34.05
34.05 x 10 to the power of six = 3405000
decimal point needs to move 5 places to go after the last zero
Answer:
y=1/5x + 8/5
Step-by-step explanation:
First you take the reciprocal of -5 which is -1/5.
Then you substitute the values to find the b.
1= -1/5(-3) +b
1=3/5+b
Add 3/5 to both sides
1+3/5= 5/5+3/5
b=8/5
Answer:
There is significant evidence to conclude that the replacement time for streetlights under the new contractor is longer than the replacement time under the previous contractor.
Step-by-step explanation:
Given the data :
6.2 7.1 5.4 5.5 7.5 2.6 4.3 2.9 3.7 0.7 5.6 1.7
The hypothesis:
H0: μ = 3.2
H1 : μ > 3.2
n = sample size = 12
The sample mean, xbar = ΣX / n
xbar = 53.2 / 12
xbar = 4.43
Using calculator;
Sample standard deviation, s = 2.147
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(4.43 - 3.2) ÷ (2.147/sqrt(12)
1.23 / 0.6197855
Test statistic = 1.985
The Pvalue using the Pvalue from Tscore calculator :
Tscore = 1.985 ; df = 12 - 1 = 11
Pvalue = 0.036
Since Pvalue < α ; We reject the Null
Hence, we conclude that the replacement time for streetlights under the new contractor is longer than the replacement time under the previous contractor.

The reasoning why they are the simplest equations are because there are hundreds of different ways in solving them they are so simple because they are the equations we were taught in 1st, 2nd, and 3rd grade. They are the heart of math...... That's what I think, hopefully that was helpful
