Simplify by combing like terms to get 2x+5
The answers would be:
the coefficient is 2
the constant is 5
There are two terms.
The 8 is in the tenths place it would look like 8/10 .8 its .08 for 8/100
Answer:
Lower limit = 1007.95 cm/s
Upper limit = 1142.05 cm/s
Step-by-step explanation:
We have to calculate a 95% CI with population's standard deviation known.
The sample is size n=60, with mean M=1075.
The confidence interval can be expressed as:
For a 95% CI, the value of z=1.96.
Answer:
$49.82
Step-by-step explanation:
To find the cost of the watch with tax, multiply the price by 1.095:
45.5(1.095)
= 49.8225
Round to the nearest hundredth:
= 49.82
So, the final cost is approximately $49.82
