Answer:
532.86
Step-by-step explanation:
just subtract starting with the numbers after the decimal place
HK consists of two part, HJ and JK
HK = HJ + JK
We know that:
HK = 12.2ft
JK = 3.1ft
HJ = ?
Let's plug our values into the equation above.
12.2ft = HJ + 3.1ft
Subtract 3.1ft from both sides.
9.1ft = HJ
Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: hourly wage of a high school student
X~N(μ;σ²)
X[bar]= $8.25
σ= $0.25
For a 95% CI for the average hourly wage for<u> 1 </u>high school student:
For this exercise you have to consider the sample size n=1
a) The margin of error of the CI is calculated as:
d=
* σ
1-α: 0.95 ⇒ α:0.05
1-α/2:0.975

d= 1.96 * 0.25= 0.49
b)
The formula for the interval is
X[bar] ±
* σ
[8.25 ± 0.49]
[7.76; 8.74]
With a 95% you'd expect the interval $[7.76; 8.74] to include the average hourly wage of one high school student in Illinois.
c)
Te calculated interval is $ [7.76; 8.74] the value $9.15 does nor fall within that acceptable range.
I hope this helps!
I believe it’s 20 m just took the test
Answer:
0.7070707070 is not an irrational number
Step-by-step explanation:
Irrational numbers cannot be expressed as a ration. These numbers are non repeating and non terminating. For example π is an irrational number.
In the given number 0.7070707070, we can see that 70 is repeating and it terminates as well.
Therefore, from the above definition of irrational numbers we can conclude that the number 0.7070707070 is not an irrational number because it terminates as well as repeated.
