Answer:
0.0228
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
This means that [tex]\mu = 200, \sigma = 25[/tex]
The probability of a player weighing more than 250 pounds is
This is 1 subtracted by the pvalue of Z when X = 250. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{250 - 200}{25}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a pvalue of 0.9772
1 - 0.9772 = 0.0228
The probability of a player weighing more than 250 pounds is 0.0228
Which inequality is true if p = 2.8?
Complete question :
Which inequality is true if p = 2.8?
3p < 10.2
13.6 ≤ 3.9p
5p > 17.1
8.5 ≥ 2.5p
Answer:
3p < 10.2
8.5 ≥ 2.5p
Step-by-step explanation:
To obtain the true expression, put p = 2.8 in all the options and choose the true inequality expression :
3(2.8) < 10.2
8.4 < 10.2 ( true)
13.6 ≤ 3.9p
13.6 ≤ 3.9(2.8)
13.6 ≤ 10.92 ( False)
5p > 17.1
5(2.8) > 17.1
14 > 17.1 ( False)
8.5 ≥ 2.5p
8.5 ≥ 2.5(2.8)
8.5 ≥ 7 (True)
Find the area of this polygon
Answer:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. ... The formula for the area of a regular octagon is 4.828 s², where s is the length of any side.

Mr. Charles gave both of his sons, Joe and Bill, $5,000. Joe deposited the money in an account that offered simple interest of 11% per year. Bill deposited the money in a bank that offered an interest of 9% compounded annually. Who would be richer at the end of 6 years and by what amount? Joe: $ , Bill: $ , . earns more.
Answer:
Bill by $85
Step-by-step explanation:
Bill : Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the money given is then subtracted from the resulting value.
Compounded annually for 6 years at 9 % interest Bill would have $8385.50.
Joe : Simple interest at 11% a year The formula we'll use for this is the simple interest formula.
P is the principal amount, $5000.00.
r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.
t is the time involved, 6year(s) time periods.
So, t is 6year time periods.
To find the simple interest, we multiply 5000 × 11 × 6 = 3300
Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),
or 5000.00 + 3300.00 = 8300.00
As you can see Bill has more by $85.

There are 15 circles and 9 triangles. What is the simplest ratio of
triangles to circles?
Answer:
9:15
Step-by-step explanation:
The required ratio of the number of triangles to the number of circles is 3:5.
Given that,
There are 15 circles and 9 triangles. What is the simplest ratio of triangles to circles is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
Here,
Number of circles = 15
Number of triangles = 9
The ratio of the triangle to the circle,
= Number of triangles / Number of circles
= 9 /15
= 3 / 5
Thus, the required ratio of the number of triangles to the number of circles is 3:5.

A square has a perimeter of 56 m. What is the length of each side?
The length of each side of the square is when the perimeter of 56 m.
The square is a four sided figure with all sides are equal in length .
The measure of all the angles of square is [tex]90^o[/tex].
Given:
The perimeter of the square = 56 m
Let, the side of square be s m.
The side of the square can be calculated using the formula:
Perimeter of square = 4 [tex]\times\\[/tex] s
56 = 4 [tex]\times[/tex] s
The value of s can be obtained by dividing both sides by 4
[tex]\dfrac{56}{4}[/tex] = s
s = 14
Thus, the length of each side is 14 m

whats 40 = 1.6m ? help please
Answer:
2.5
Step-by-step explanation:
Divide each side by 1.6 to get m alone, thus getting the answer, so 1.6m/1.6 and 40/1.6
The solution of the equation 40 = 1.6 m is m is equals to 25.
Given Equation:
40 = 1.6m
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
First, write the decimal 1.6 in fraction as 16/10.
So, the equation can be written as
40 = 16/10 (m)
40 x 10 = 16m
400 = 16 m
Now, divide both side of equation by 16
400/ 16= 16 m/ 16
25 = m
Therefore, the value of m is 25.

Please help find the measurement of exterior angle MBI
Answer:
The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with
N sides. It is equal to 360 o N .
Step-by-step explanation:
Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.
However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to 360 o .
It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of
360 o . So, if all exterior angles are equal, like in a regular polygon, each one equals to 360 o N .
It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is ( N − 2 ) ⋅ 180 o .
Dividing the above by N
we will obtain a value of an interior angle: ( N − 2 ) ⋅ 180o N .
Therefore, exterior angle of a regular polygon is 180 o − ( N − 2 ) ⋅ 180 o N = 360 o N
Tito used 1 1/8 gallons of paint to paint 3/7 of a fence. How many gallons of paint would it take to paint the whole fence?
1 1/8:3/7
How many gallons does it take to cover 1/7 of the fence?
1 1/8 divided by 3= 9/8 divided by 3/1 or 9/8*1/3=9/24 or 3/8.
It takes 3/8 of a gallon to paint 1/7 of a fence.
7*3/8= 7/1*3/8= 21/8.
I believe your answer is: it takes 21/8 or 2 5/8 gallons of paint to paint the whole fence.

Pleasee help!! “It costs $2.75 to buy 3/4 lb of grapes. How much would it cost to purchase 9.5 lbs of grapes? Explain or show your reasoning.”
Answer:
$34.83
Step-by-step explanation:
First convert 3/4 to decimal form: 3/4 = 0.75
Create a proportion using similar rates:
$2.75 / 0.75 lb = x / 9.5 lb
where "x" represents the price of the 9.5 lbs of grapes we need to find.
Solve for x by multiplying both sides by 9.5 lb to isolate x completely
2.75 * 9.5 / 0.75 = x
Therefore x = $34.83
