X + (x + 1) + (x + 2) + (x + 3) = -26
Even though it says negative, the same rules apply.
4x + 6 = -26
4x = -32
x = -8
-8, -7, -6, -5
Hope this helps!
$6572×1.23= $8083.56
Just have to multiply the monthly expenses by the taxes. and to make things faster, instead of adding at the end, you can just multiply the original answer by 1 plus whatever the other number is. in this case, it is 1.23. does that make sense?
Answer:
The area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²
Step-by-step explanation:
Given : A regular hexagon with an apothem 10.4 yards long and side 12 yards long.
We have to find the area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long.
Since, the Given hexagon is a regular hexagon.
So, each side make equal angle with mid point.
Thus, Area of each triangle =
base = 12 yards
height = 10.4 yards.
Thus, Area of each triangle =
Since, there are 6 triangles.
so area of hexagon = 6 × Area of triangle
area of hexagon = 6 × 62.4 = 124.8 yards²
Thus, The area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²
Answer:
Now we can claculate the p value with this formula:
If we use a signifiacn level of 5% we see that the p value is higher than 0.05 so then we have enough evidence to fail to reject the null hypothesis and we can't conclude that the true proportion is significantly higher than 0.3 at 5% of significance.
Step-by-step explanation:
Information to given
n=735 represent the random sample taken
X=203 represent the number of people who have their prostate regularly examined
estimated proportion of people who have their prostate regularly examined
is the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to test if the true proportion is less than 0.3, the ystem of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
Now we can claculate the p value with this formula:
If we use a signifiacn level of 5% we see that the p value is higher than 0.05 so then we have enough evidence to fail to reject the null hypothesis and we can't conclude that the true proportion is significantly higher than 0.3 at 5% of significance.
