Answer:
um whats the question
Step-by-step explanation:
The concept used here is the place values. Each digit of a number holds it own value that is determined by its relative location within the number. Starting on the rightmost digit, the value increases by 10. The ones digit has a value of 1. The tens digit has a value of 10. The hundreds value has a value of 100.
The rightmost 4 has a value of 1, so its exact value is 4*1 = 4. The middle 4 is the tens place, so its exact value is 4*10 = 40. The third 4 from the right is in the hundreds place, so its exact value is 4*100 = 400.
Answer: x=9
Explanation:
8x-13=59
8x-13+(13)=59+(13)
simplify add the numbers
8x=72
Divide both sides of the equation by the same term
8x=72
8x/8=72/8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=9
Answer:
At 0.10 significance level, reject H0
At 0.05 significance level, reject H0
At 0.01 significance level, fail to reject H0
At 0.001 significance level, fail to reject H0
Step-by-step explanation:
The null hypothesis is rejected if the p-value is less than or equal to the significance level.
Fail to reject the null hypothesis if the p-value is greater than the significance level.
At 0.1 and 0.05 significance level, the null hypothesis is rejected because the p-value (0.0174) is less than the significance levels.
At 0.01 and 0.001 significance level, fail to reject the null hypothesis because the p-value (0.0174) is greater than the significance levels.
N = 20 + 7y
Joe is starting with 20 Apple trees, so the equation starts with:
N = 20
And each year afterwards, 7 more trees will be planted, so let's represent that as 7y where 7 is the number of trees to plant each year and y is the number of years that this has been going on. Finally, add that to the initial tree count, giving:
N = 20 + 7y
