Answer:
<em>The percentage of males are not at least 172 pounds</em>
P(X⁻ ≥ 172) = 0.26
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that 74% of 19 -year -old males are at least 172 pounds
Let 'X' be a random variable in a binomial distribution
P( X≥172) = 74% = 0.74
<em>we have to find that the percentage of males are not at least 172 pounds</em>
<u><em>Step(ii):-</em></u>
<em>The probability of males are not at least 172 pounds</em>
P(X⁻≥172) = 1- P( X≥172)
= 1- 0.74
<em> = 0.26</em>
<u><em>Final answer:-</em></u>
<em>The percentage of males are not at least 172 pounds</em>
P(X⁻ ≥ 172) = 0.26
<u><em></em></u>
Answer:
1) True
2) False
3) False
4) True
Step-by-step explanation:
1) True
Anything over 100% is larger than the original.
2) False
Since it is 225% bigger, you multiply 4 by 2.25.
4 x 2.25 = 9
3) False
If it is 225% larger, it means that it is 2.25 times larger
4) True
Explanation:
The equation for this problem can be modeled in y = mx + b form.
m represents the rate of change and b represents the initial value or constant.
y = 10x + 20
x represents the number of hours he spent delivering newspapers
y is his total money after whatever number of hours he worked
The rate is 10, because it determines how much money he earns for each hour.
The y-intercept is 20, representing the starting amount of money in his bank account.
Answer:
$6
Step-by-step explanation:
Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.
15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.
- ➣ Circle:- A two-dimensional geometric figure, a line, consisting of the set of all those points in a plane that are equally distant from a given point (center).
- ➣ Circumference:- The line that bounds a circle or other two-dimensional figure
★ also circumference of a circle is also known as it's perimeter
- ➣To find circumference of circle when use formula
- ➢ r = radius (25inch.)
- ➢ value of π is 3.14
★ Hence circumference of circle=157inch
Hope it helps !
