Person is randomly selected. what is the probability that the person is:
a.color-blind given that the person is male? 69/133
b.male and color-blind?
The probability that a person is color-blind given they are male is 69/133. Calculating the probability of being both male and color-blind requires additional information about the total and male population. This showcases the importance of context in probability calculations.
Explanation:The question involves calculating the probability of specific conditions related to color-blindness and gender. To address both parts of the question:
For part a, the probability that a person is color-blind given that the person is male is directly provided as 69/133. This means out of all males considered, approximately 51.88% have color-blindness.For part b, determining the probability of being male and color-blind would require more specific data, such as the total number of people or the ratio of males to females, and how many among them are color-blind. If we consider the probability for a male to be color-blind is 69/133, this probability is only valid within the male population; it does not directly give us the probability of being both male and color-blind unless the total population is known and the proportion of males within that population is specified.Understanding probabilities in genetics, like color-blindness, often involves considering various factors including the overall population and specific subgroups within that population (such as males in this case).

The perimeter of an equilateral triangle is 156 feet find the length of each side
Answer:
52 feet
Step-by-step explanation:
In an equilateral triangle, all three sides are equal in length.
If we let s represent the length of one side, the perimeter P of the triangle can be expressed as:
[tex]P = 3s[/tex]
Given that the perimeter is 156 feet, we can set up the equation:
[tex]3s = 156[/tex]
To find s, divide both sides of the equation by 3:
[tex]\dfrac{3s}{3}=\dfrac{156}{3}[/tex]
[tex]s=52[/tex]
Therefore, the length of each side of the equilateral triangle is:
[tex]\large\boxed{52 \textsf{ feet}}[/tex]
Clyde Cement wants to analyze a shipment of bags of cement. He knows the weight of the bags is normally distributed so he can use the standard normal distribution. He measures the weight of 600 randomly selected bags in the shipment. Next, he calculates the mean and standard deviation of their weights. The mean is 50 lbs and the standard deviation is 1.5 lbs. What percentage of the bags of cement will weigh less than 50 lbs.? 50 60 75 80
Answer:
50%
Step-by-step explanation:
First, draw a normal distribution plot to use for the analysis of the data. Starting at the mean in the centre. Add one standard deviation for each interval to the right, and subtract one standard deviation for each interval to the right. See attached image. According to the empirical rule, 68% of data lies within one standard deviation of the mean, 95 % of the data is within two st. dev. and 99.7% of the data is within 3 st. dev. of the mean.
From the graph it can be deducted that half of the data will lie below 50, which makes it 50%.
An easier way of determining the answer is to use the definition of a mean. A mean is the number that,when all the data is placed in ascending order, lies right in the middle of all the data.
In a normal distribution, 50% of the values lie below the mean. Therefore, 50% of the bags will weigh less than 50 lbs.
The question involves understanding the properties of a normal distribution where the mean weight of the bags is 50 lbs, and the standard deviation is 1.5 lbs. To determine the percentage of bags weighing less than 50 lbs, we look at the standard normal distribution. Since 50 lbs is the mean, exactly 50% of the bags will weigh less than this amount. This is because, in a normal distribution, the mean divides the distribution so that half the values are below the mean and half are above it.

Rohan is checking in poodles for a dog show. A miniature poodle must be between 10 in. and 15 in. at the shoulder. The body length must be no more than 16 in. In addition, the poodle’s shoulder height must be no more than 1 in. longer than its body length.
The graph shows the feasible region, where x represents the poodle’s body length and y represents the shoulder height.
Which ordered pairs meet all the constraints for a successful poodle measurement and make sense in context of the situation?
Select each correct answer.
(15, 11)
(11, 9)
(11, 14)
(10, 12)
(12, 10.5)
Answer:
(15, 11) and (12, 10.5).
Step-by-step explanation:
Let x represents the poodle’s body length and y represents the shoulder height.
A miniature poodle must be between 10 in. and 15 in. at the shoulder.
[tex]10\leq y\leq 15[/tex]
The body length must be no more than 16 in.
[tex]0\leq x\leq 16[/tex]
The poodle’s shoulder height must be no more than 1 in. longer than its body length.
[tex]y\le1+x[/tex]
From the below figure it is clear that only two points (15, 11) and (12, 10.5) lie in the feasible region.
Therefore, ordered pairs (15, 11) and (12, 10.5) meet all the constraints for a successful poodle measurement and make sense in context of the situation.
For the following figure, complete the statement for the specified points.
Points A, S, Q, and R are _____.
collinear
coplanar
both collinear and coplanar
neither collinear nor coplanar
Answer:
D. Neither collinear nor coplanar
Step-by-step explanation:
We know that,
Collinear points - are the points which lie in the same straight line.
Coplanar points - are the points which lie in the same plane.
From the figure, we see that,
The points A, S, and R lie in the same line but Q does not lie in the same line.
The points A and Q lie in the same plane but others do not lie in the same plane.
Hence, we get,
These points are neither collinear nor coplanar.
Thus, option D is correct.

A line slope is 1 and its y intercept is 2 what is its equation in slope intercept form
Write your answer using integers proper fractions and improper fractions in simplest form
[tex]\[ y = x + 2 \][/tex] is the equation in slope-intercept form.
To find the equation of a line given its slope and y-intercept, we use the slope-intercept form: ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept.
Given that the slope ( m = 1 ) and the y-intercept ( b = 2 ), we substitute these values into the equation:
[tex]\[ y = 1x + 2 \][/tex]
[tex]\[ y = x + 2 \][/tex]
This is our equation in slope-intercept form.
Now, let's show the detailed calculation:
1. Start with the slope-intercept form: ( y = mx + b ).
2. Substitute ( m = 1 ) and ( b = 2 ) into the equation: ( y = 1x + 2 ).
3. Simplify: ( y = x + 2 ).
So, the equation of the line is \( y = x + 2 \). This means the line has a slope of 1 and passes through the point (0,2) on the y-axis.

Write an equation of a line that includes the point (22,12) and has a slope of 4 in standard form
The equation of the line that passes through the point (22,12) and has a slope of 4 is; y = 4x - 76
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Where x₁ - x coordinate and y₁ - y coordinate
Point (22,12)
Then Slope m =4
Now Write the equation as
y - 12 = 4(x - 22)
y = 4x - 76
Hence, the standard form of the line is; y = 4x - 76

A tow truck charges a service fee of $50 and an additional fee of $1.75 per mile. What distance was Marcos's car towed if he received a bill for $71?
To find the distance Marcos's car was towed, subtract the service fee from the total bill amount. Then divide the remaining bill amount by the additional fee charged per mile. The distance towed is 12 miles.
Explanation:To find the distance Marcos's car was towed, we need to subtract the service fee from the total bill amount. The additional fee charged per mile is $1.75, so we can calculate the number of miles towed by dividing the remaining bill amount by $1.75.
Let's assume the distance towed is 'x' miles.
The total bill amount is $71, and the service fee is $50. Therefore, the additional fee charged for the distance towed is $71 - $50 = $21.
So we can write the equation:
$21 = $1.75 * x
To solve for 'x', we divide both sides of the equation by $1.75:
x = $21 / $1.75
x = 12 miles
Therefore, Marcos's car was towed for a distance of 12 miles.

A box contains 14 scarves in unique colors. If 4 scarves are picked randomly from the box,__________ different combinations are possible if the order doesn't matter.
Answer: 363242880
Step-by-step explanation:
We know that the of to calculate the number of combinations, we use the formula :-
[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex], where n : the total number of items
r: the number of items being chosen at a time.
Given: The total number of scarves contained in a box= 14
The number of scarves picked = 4
The number of different combinations is given by :-
[tex]^{14}C_4=\dfrac{14!}{(14-4)4!}\\\\=\dfrac{14\times13\times12\times11\times10!}{10!4!}\\\\=\dfrac{14\times13\times12\times11}{4\times3\times2}=363242880[/tex]
Hence, If 4 scarves are picked randomly from the box, 363242880 different combinations are possible if the order doesn't matter.
Elizabeth bought 4 drinks and some nachos. The nachos cost $6, and she spent a total of $18. How much did each drink cost? Use d to represent the cost of each drink. A. ; each drink cost $4. B. ; each drink cost $6. C. ; each drink cost $2. D. ; each drink cost $3.
The drink costs $3 for each.
The correct option is (D)
What is Algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Number of drinks= 4
Cost of Nachos = $6.
Total money spend =$18
After removing the prices from total money spend, we will get the price for 4 drinks
So, 18-6= $12
Cost for 4 drinks =12
Cost of 1 drink =12/4 = $3
Hence, each drink cost $3.

rabbits population can double every 30 days if there are 10 rabbits on a farm how many rabbits will be on the farm after 120 days
Answer:
Step-by-step explanation:
= 10(1+1)^4 the final answer is 160
How I got 4 is you divide 30\ 120 =4
After 120 days there will be 160 rabbits on the farm.
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
Rabbits population can double every 30 days.
Initially there are 10 rabbits in a farm.
So, after 30 days there would be 10 × 2 = 20 rabbits.
After next 30 days, there would be
20 × 2
= 10 × 4
= 10 × 2²
= 40 rabbits.
Let t be the number of days and x be the number of rabbits.
So, we have an equation:
[tex]x=10\times2^{\frac{t}{30} }[/tex]
No, we find the number of rabbits after 120 days.
t = 120
So, the equation becomes,
[tex]x=10\times2^{\frac{t}{30} }\\\\x=10\times2^{\frac{120}{30} }\\\\x=10\times2^{4}\\\\x=10\times 16\\\\x=160[/tex]
Therefore, after 120 days there will be 160 rabbits on the farm.
