the average number of pounds of red meat a person consumes each year is 196 with a standard deviation of 22 pounds find the probability that the mean of the sample will be less than 200 pounds
Answers
The mean of the sample will be less than 200 pounds is .571 using standard deviation
What is standard deviation?
The standard deviation is a statistician's way of gauging how much a group of numbers can vary or be dispersed. The values tend to be close to the set's mean when the standard deviation is low, while the values are dispersed over a larger range when the standard deviation is high.
Given that ,
mean = μ = 196
standard deviation = σ= 22
P(x < 200) = P((x - μ) / σ < (200 - 196) / 22)
= P(z < 0.18)
Using the standard normal.
P(x < 200) = 0.5714
Probability = 0.5714
Hence the Probability will be .571 using standard deviation

Given that, PQ is parallel to RS . PR and are perpendicular to PQ and RS.
What are parallel lines?Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.
The slope of parallel lines is equal to each other.
If PQ is parallel to RS.
PR is perpendicular to PQ and RS.
QS is also perpendicular to PQ and RS.
The figure that will be formed using the two parallel lines, and the two perpendicular is a square.
When two lines are parallel to each other and the end points of the parallel lines are used to draw perpendiculars, then the line segments PQ and RS will be congruent.
By the property of Congruence, the ratio of the lengths PR and QS is equal to 1:1.

A lorry travels at a speed of 45 km/h for 2 hours from factory P to factory Q. Then the lorry takes 30 minutes more for its return journey. Calculate the average speed.
Answers
40 Km/h will be the average speed of the lorry for the overall journey from factory P to Q and again from factory Q to P.
The distance between the factories can be calculated by the Speed-Time relation.
Total Distance = Total Speed x Total Time = 45Km x 2 = 90Km
To calculate the Average Speed, Total Distance and Total Time are the essential parameters.
Total Distance = 90 + 90 = 180Km
Total Time = 2 + 2.5 = 4.5h
As per the formula of Average speed:
Average speed = Total Distance/ Total Time
Average speed = 90+90Km / 4.5h
= 40Km/h

A fair die is rolled, and if the die has an even roll (e.g. 2, 4, or 6), he or she wins nothing. If it is an odd roll, he or she wins the amount of money (in dollars on the face of the die—e.g. if he or she rolls a 1, he or she wins $1; a 3, he or she wins $3; a 5, he or she wins $5). The random variable [tex]X[/tex] represents the amount he or she wins per play of the game, not including how much he or she pays.
Part 1: Complete the given table.
Part 2: How much can someone expect to win on average per play of the game? Should he or she pay $3 to play this game? Why or why not?
Answers
Using a discrete probability distribution, it is found that:
1. The table is completed at the end of the answer.
2. The expected earnings for a single play of the game are of $1.5. Since $3 is greater than the average earnings, a person should not pay $3 to play this game.
What is the mean of a discrete distribution?The expected value, also called the mean, of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
For this problem, we have that:
If it is an even roll, the person wins nothing. Out of 6 possible outcomes, 3 are even numbers, hence P(X = 0) = 3/6 = 1/2.If it is an odd roll, the person wins the amount played, hence P(X = 1) = P(X = 3) = P(X = 5) = 1/6.The table completed with these probabilities is given at the end of the answer.
Hence the expected earnings for the game are given as follows:
E(X) = 1/2 x 0 + 1/6 x (1 + 3 + 5) = $1.5.
If a person paid $3, the expected earnings would be of:
1.5 - 3 = -$1.5.
Negative earnings, hence the person should not pay $3 to play this game.

Jenna is making a scarf. She needs 23 /4 feet of yarn. Each yarn bundle is 11 1/2feet. How many bundles does Jenna need? How much will be left over?
Answers
Given:
The length of yarn needed, l=23 1/4 feet.
The length of a yarn bundle, L=11 1/2 feet.
The number of bundles of yarn needed can be calculated as,
[tex]\begin{gathered} n=\frac{l}{L}=\frac{23\text{ }\frac{1}{4}}{11\frac{1}{2}} \\ n=\frac{\frac{23\times4+1}{4}}{\frac{11\times2+1}{2}} \\ n=\frac{\frac{93}{4}}{\frac{23}{2}} \\ n=\frac{93}{4}\times\frac{2}{23} \\ n=\frac{93}{2}\times\frac{1}{23} \\ n=\frac{93}{46} \\ n=2\frac{1}{46} \end{gathered}[/tex]Therefore, 3 bundles is needed by Jenna to make the scarf.
The part of leftover yarn is,
[tex]\begin{gathered} N^{}=3-2\frac{1}{46} \\ =3-(2+\frac{1}{46}) \\ =1-\frac{1}{46} \\ =\frac{46-1}{46} \\ =\frac{45}{46} \end{gathered}[/tex]Hence, 45/46 part of a bundle of yarn will be left.
Now, the length of leftover yarn is,
[tex]\begin{gathered} l^{\prime}=N\times L \\ =\frac{45}{46}\times11\frac{1}{2} \\ =\frac{45}{46}\times\frac{11\times2+1}{2} \\ =\frac{45}{46}\times\frac{23}{2} \\ =\frac{45}{2}\times\frac{1}{2} \\ =\frac{45}{4} \\ =11\frac{1}{4}\text{feet} \end{gathered}[/tex]Therefore, 111/4 feet of yarn will be left.
Tricia buys 18 apples for $27. The total cost, c, of the apples is proportional to the number of apples, a, that she buys. How much does one apple cost? Create an equation using c and a to represent the proportional relationship.
Answers
If Tricia buys 18 apples for $27 and the total cost c of the apples is proportional to the number of number of apples a that she buys, then the cost of one apple is $1.5 and the relationship between c and a is c = 1.5a
The cost of 18 apples = $27
Here we have to use unitary method to find the cost of one apple
The cost of one apple = 27/18
= $1.5
Consider the total cost of the apples as c and the number of apples she bought as a
Then the relationship will be
c ∝ a
c = ka
Here the k is the constant that will be the cost of one apple
The cost of one apple = $1.5
Then the relationship will be
c = 1.5a
Hence, if Tricia buys 18 apples for $27 and the total cost c of the apples is proportional to the number of number of apples a that she buys, then the cost of one apple is $1.5 and the relationship between c and a is c = 1.5a

Answer:
x = 45
y = 20
Step-by-step explanation:
Since the two horizontal lines are parallel
angles with measures of 6y and 3y are supplementary angles and add up to 180°
So 6y + 3y = 180
9y = 190
y = 20
Similary 2x and 90 are supplementary angles
2x + 90 = 180
2x = 90°
x = 45
Answer:
x=45 y=20
Step-by-step explanation:
you can tell x is 45 because is is a right angle and those are 90 degrees.
9y+180=360 360 because that is the sum of all the angles added up in a quadrilateral.

Answers
The relationship between x and y is y = 0.25x + 1.
Define slope intercept form.Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form. One of the formulas used to get a line's equation is the slope-intercept formula. Y = mx + b is the slope-intercept formula for a line with slope m and y-intercept b. Any point on the line is (x, y) in this case.
Given,
A basket with 4 apples weighs 2 pounds.
Slope intercept form:
y = mx + b
Equation:
2 = 4m +b ..(1)
A basket with 12 apples weighs 4 pounds
4 = 12m + b ... (2)
Solving,
2 = 4m + b
4 = 12m + b
4 = 8m
Divide the second equation by 8:
2 = 4m + b
m = 0.25
b = 1
