Probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
According to the question
For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 9.
Probability that a randomly selected male's systolic blood pressure will be less than 100
P(x < 100)
By using normalized normal distribution
= [tex]N(\frac{100-105}{9} )[/tex]
= [tex]N(\frac{-5}{9} )[/tex]
We have N(-a) = 1 - N(a), a>0
= 1 - [tex]N(\frac{-5}{9} )[/tex]
= 1 - N(0.556)
= 1 - 0.6026
= 0.3979
≈ 0.397 (nearest thousandth)
So, probability that a randomly selected male's systolic blood pressure will be less than 100 is 0.397.

Use substitution to solve the
following system of equations.
9x + 5y = 32 AND y = -3x + 4
Answers
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10

Leah is mixing peanut butter candy (p) that sells for $3.60 per pound with chocolate candy (c) that sells for $2.00 per pound. She needs 50 pounds of the mixture to sell in her store for $2.16 per pound. Which system of linear equations can Leah use to determine the number of pounds of each candy to use?
Answers
Answer:
45 pounds of the chocolate candy and 5 pounds of the peanut butter candy.
Step-by-step explanation:
let's define the variables:
p = pounds of peanut butter candy she uses
c = pounds of chocolate candy she uses.
We know that she wants to have a total of 50 pounds of the mixture, then we will have that:
p + c = 50
We also want that these 50 pounds sell for $2.16 per pound.
Then we must have that the price for the candies in the mixture must be equal to the desired price, we can write this as:
p*$3.60 + c*$2.00 = (50 )*($2.16 )
Then we have the system of equations:
p + c = 50
p*$3.60 + c*$2.00 = (50)*($2.16) = $108
To solve this, we first need to isolate one of the variables in one of the equations. I will isolate p in the first equation to get:
p = 50 - c
Now we can replace this in the other equation to get:
(50 - c)*$3.60 + c*$2.00 = $108
Now we can solve this for c.
$180 - c*$3.60 + c*$2.00 = $108
$180 - c*$1.60 = $108
$180 - $108 = c*$1.60
$72 = c*$1.60
$72/$1.60 = c = 45
This means that she should use 45 lb of the chocolate candy, and using the equation:
p + c = 50
p + 45 = 50
p = 50 - 45 = 5
p = 5
She should use 5 lb of the peanut butter candy.

A square is attached to a semicircle to make the figure shown in the diagram below .
if the radius of the semicircle is 4 meters ,what is the aproximate area of the figure .
Answers
Answer:
C) 89.12 m^2
Step-by-step explanation:
You can find the area of this figure by finding the areas of both shapes (semicircle and rectangle) then adding both areas.
To find the area of a semicircle, use this formula:
1/2πr^2 (1/2 x 3.14 x radius x radius)
Here, this radius is 4.
Now, we just plug in the numbers.
[3.14 is always used for π (pi)].
1/2 x 3.14 x radius x radius
↓
1/2 x 3.14 x 4 x 4 = 25.12
25.12 is the area of the semicircle.
Now, we must find the area of the square.
SQUARES ARE HAVE EQUAL SIDES, SO TO FIND THE AREA, WE SIMPLY MULTIPLY A SIDE LENGTH BY ITSELF TWICE.
8 x 8 = 64.
Now that we have both areas, we add to find the area of the figure.
25.12 + 64 = 89.12
Therefore, the area of this figure is 89.12 meters^2.

A rectangle has a length of (3x - 4) units and a width of (2x + 3) units. What is the perimeter of the rectangle in terms of x?
Answers
Answer:
(10x-2) units
Step-by-step explanation:
The perimeter of a rectangle is 2*length+2*width.
2(3x-4)+2(2x+3)
=6x-8+4x+6
=10x-2
The perimeter of a rectangle is ( 10x - 2 ).
Here,
The length of rectangle is (3x - 4) units.
The width of rectangle is (2x + 3) units
We have to find the perimeter of a rectangle.
What is the perimeter of a rectangle?
The sum of two times of length and width is called the perimeter of a rectangle.
Now,
The length of rectangle is (3x - 4) units.
The width of rectangle is (2x + 3) units
Since, The perimeter of a rectangle = 2 (length + width)
Hence, The perimeter of a rectangle = 2(3x - 4 + 2x + 3)
= 2 (5x -1)
= 10x - 2
Therefore, The perimeter of a rectangle is ( 10x - 2 ).

On a given day, eight rabbits, 12 mice, and four snakes are present on the mountain range. If each animal is equally likely to be caught and consumed, what is the probability that the wolf will eat two rabbits?
Answers
Answer:
7 / 69
Step-by-step explanation:
Rabbit = 8
Mice = 12
Snake = 4
Total = (8 + 12 + 4) = 24
If each animal has equal probability of being caught ;
Probability of catching a rabbit ;
Number of rabbits / total number of animals
P(catching 1 rabbit) = 8 / 24 = 1/3
P(catching 2nd rabbit) :
Number of rabbits left = 8 - 1 = 7
Total number of rabbits = 24 - 1 = 23
Hence, P(catching 2nd rabbit) = 7 /23
Probability of catching two rabbits :
1 /3 * 7/ 23 = 7 / 69

If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
