THE DECIMAL 104.3 BECOMES 1,043 WHEN MULTIPLIED BY 10. THE SAME NUMBER BECOMES 10.43 WHEN MULTIPLIED BY 0.10 EXPLAIN WHY
2 answers:
Answer:
When we multiply the number 104.3 by 10, the decimal is shifted to one right place. Because whenever a decimal value is multiplied by 10, the decimal is shifted to one place on the right side.
When we multiply 104.3 by 0.10, we can say that we are multiplying it by or simply we are dividing 104.3 by 10.
When we divide any number by 10, we move the decimal to one left place.

Answer:
No, there is not enough evidence to support the claim that true average task time with armor is less than 2 seconds.
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that true average task time with armor is less than 2 seconds.
Then, the null and alternative hypothesis are:
The significance level is 0.01.
The sample has a size n=52.
The sample mean is M=1.95.
As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=0.2.
The estimated standard error of the mean is computed using the formula:
Then, we can calculate the t-statistic as:
The degrees of freedom for this sample size are:
This test is a left-tailed test, with 51 degrees of freedom and t=-1.803, so the P-value for this test is calculated as (using a t-table):
As the P-value (0.039) is bigger than the significance level (0.01), the effect is not significant.
The null hypothesis failed to be rejected.
There is not enough evidence to support the claim that true average task time with armor is less than 2 seconds.
Answer:
f(x) = + 10
Step-by-step explanation:
Year one would be 10 + 3
Year two would be (3*3)+10
year three would be (3*3*3)+10
Which easily simplifies into + 10.
