there are 750 spectators in the stadium,of which 420 are women and the rest are men what percent of the spectators are women? and what percent of the spectators are men?
Answers
The percentage of women spectators is 56%.
The percentage of men spectators is 44%.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of spectators = 750
Number of women = 420
Number of men = 750 - 420 = 330
The percentage of women.
= 420/750 x 100
= 56%
The percentage of men.
= 330/750 x 100
= 44%
Thus,
56% of women are spectators.
44% of men are spectators.

Answer:
The cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
Step-by-step explanation:
Let us assume that the cost of one muffins be x.
Let us assume that the cost of one 1 quarts of milk be y.
As given
The cost of 8 muffins and 2 quarts of mil is $18.
Than the equation becomes
8x + 2y = 18
As given
The cost of 3 muffins and 1 quart of milk is $7.50.
Than the equation becomes
3x + 1y = 7.50
Two equations are
8x + 2y = 18 and 3x + 1y = 7.50
Multiply 3x + 1y = 7.50 by 2 and subtracted from 8x + 2y = 18 .
Thus
8x - 6x + 2y - 2y = 18 - 15
2x = 3
x = 1.5
Put x = 1.5 in 3x + 1y = 7.50
3 × 1.5 + y = 7.50
y = 7.50 - 4.5
y = 3
Therefore the cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .

Answer:
Length = 17m
Width = 11m
Step-by-step explanation:
Expression for the area of the rectangle = 6x² + 19x + 15
Factorising the quadratic expression
6x² + 19x + 15 = (6x² + 9x) + (10x + 15) = 3x(2x + 3) +5(2x + 3) = (3x + 5)(2x + 3)
x = 4m
Length = 3x + 5 = 3(4) + 5 = 12 + 5 = 17m
Width = 2x + 3 = 2(4) + 3 = 8 + 3 = 11m

D. 7x + 2y < 2
Explanation:
The two general forma of the inequality are:
y < mx + c .........> In this case, shading is below the boundary line
y > mx + c .........> In this case, shading is above the boundary line
Since we are looking for the inequality with shading below the boundary line, therefore, we are looking for an y < mx + c format
Now, let's check the givens:
y - x > 5
Rearranging, we would get:
y > x + 5
The shading is above the boundary line. This option is incorrect
2x - 3y < 3
Rearranging, we would get:
2x - 3 < 3y
The shading is above the boundary line. This option is incorrect
2x - 3y < 7
Rearranging, we would get:
2x - 7 < 3y
The shading is above the boundary line. This option is incorrect
7x + 2y < 2
Rearranging, we would get:
2y < -7x + 2
The shading is below the boundary line. This option is correct
3x + 4y > 12
Rearranging, we would get:
4y > -3x + 12
The shading is above the boundary line. This option is incorrect

Answer:
The answer is: expected value is -$0.88
Step-by-step explanation:
Given is, the he bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is won, on average, with a bid of $160. So, $160 in 1¢ steps means 16000 bids.
Therefore, a person invest $1 with a 1/16000 probability of a $2000 return.
Noe, the expected value will be =
= -1+0.125 = -0.875 ≈ -$0.88
Hence, the answer is -$0.88
