Answer:

A) p(male)=20/30=2/3

b) p(female) = 10/30=1/3

c) p(11th grade) = 12/30=2/5

d) p(12th grade) = 18/30 = 3/5

e) p( girl and in 11th grade) =4/30=2/15

F) p(12 th grade and female) = 6/30 = 1/5

g) p(male and in 12th grade) = 12/30 = 2/5

h) p(male and if we know the student is female) = 0 if we know the student is male then she can't be male again. these are mutuallyinclusive event and they can't occur at once.FOR more details and solutions,clarification and more explanation contact me via my g mail at [email protected] and I will keep in touch....please leave your comment in thisg mail which is my tutor g mail account please.

Any REAL help on #16 above??? Can someone check my answer?

babymother [125]

Answer:

The answer to your question is:th first option is correct.

Step-by-step explanation:

Here we have and hyperbola with center (0, 1), and the hyperbola is horizontal because x² is positive.

Equation

y - k = ± $\frac{b}{a} (x - h)$

Process

Find a, b

a² = 9

a = 3

b² = 5

b = √5

h = 0 and k = 1

Substitution

y - 1 = ± $\frac{√5}{3} (x - 0)$

Equation 1

y = $\frac{\sqrt{5} }{3} x + 1$

Equation 2

y = - $\frac{\sqrt{5} }{3} x + 1$

A deli is offering two specials. The roast beef special gives a profit of $2.30 per sandwich, and the turkey special gives a pro

nikklg [1K]

Answer:

The constraints are as follows;

1) 2·x + 2·y ≤ 120

2) 3·x + 4·y ≤ 160

3) x = 2.30

4) y = 3.10

5) P = 2.3·x + 3.10

Step-by-step explanation:

The question is a word problem, with the analysis as follows;

The profit from the roast beef special per sandwich = $2.30

The profit from the turkey special per sandwich = $3.10

The number of slices of bread in the roast beef special = Two slices

The number of slices of cheese in the roast beef special = Three slices

The number of slices of bread in the turkey special = Two slices

The number of slices of cheese in the turkey special = Four slices

The number of slices of bread the deli has = 120 slices

The number of slices of cheese the deli has = 160 slices

Let 'x' and represent the number of roast beef special and 'y' represent the number of turkey special the deli makes, then we have the constraints as follows;

For the number of slices of bread used;

2·x + 2·y ≤ 120...(1)

For the number of slices of cheese used;

3·x + 4·y ≤ 160...(2)

x = 2.30

y = 3.10

The profit 'P' is given by the following equation

P = 2.3·x + 3.10.

Find the area and circumference of the circle below: Diameter - 14 cm

MAVERICK [17]

Answer:

Area : 153.86cm

Circumference: 43.96cm

Step-by-step explanation:

To Find:

Area __ cm

Circumference__ cm

Given:

Since, it given that the Diameter is 14 cm

Diameter which is any straight line segment that passes through the center of the circle.

Radius which is half of diameter

Note:

A = πr ² {Area Formula}

C = rd {Circumference Formula}

pi also known as π = 3.14 {approximately }

"r " means Radius

"d " means diameter

c = circumference

a = area

Solve:

A = πr ²

Since radius is half of the diameter then...

14/2 = 7

Radius = 7

A = 3.14(7)² { (7)² means 7 × 7 Not 7 × 2 }

A = 3.14(49) { 7 × 7 = 49}

A = 153.86

C = rd

C = 3.14(14)

C = 43.96

Area : 153.86cm

Circumference: 43.96cm
