You want to know how many of the students at your school eat lunch everyday. Of the 3545 students you randomly ask 300. 220 say yes, 70 say no and 10 don't know. Based on your survey what is the best estimate of the number of students who eat lunch everyday?
a.) 3300
b.) 2600
c.) 827
d.) 1500
(no links please!)

Answers

Answer 1

Answer:

B) 2600

Step-by-step explanation:

Set up a proportional equation and solve:

220/300=x/3545

(220)(3545)=300x

779900=300x

2599.666=x

2600=x

Your best estimate is B) 2600

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)

Answers

Answer:

a + (b + c) = (a + b) + c

Step-by-step explanation:

a= (-12), b = 4, c = (-25)

[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]

Answer:

GIVEN :-

a = -12b = 4c = -25

TO VERIFY :-

a + (b + c) = (a + b) + c

SOLUTION :-

Find the values of L.H.S. & R.H.S.

L.H.S. :-

Put all values in → [tex]\boxed{a+(b+c)}[/tex]

⇒ -12 + [4 + (-25)]

⇒ -12 + (4 - 25)

⇒ -12 + (-21)

⇒ -12 - 21

⇒ -33

R.H.S. :-

Put all values in → [tex]\boxed{(a+b)+c}[/tex]

⇒ (-12 + 4) + (-25)

⇒ -8 - 25

⇒ -33

CONCLUSION :-

L.H.S. = R.H.S.

⇒ a + (b + c) = (a + b) + c

2x - x = 7 + 1

x = 8.

QS = x + 4 = 8 + 4

= 12.

But QS = SA, so SA =12.

What number should Rihanna use for the height of the parallelogram if she uses 28 inches for the base

Answers

Answer:

[tex]Height = 7in[/tex]

Step-by-step explanation:

Given

See attachment for parallelogram

[tex]Base = 28in[/tex]

Required

What is the height?

The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.

From the question, we have:

[tex]Base = 28in[/tex]

Also from the question, the difference between the two parallel sides is 7in.

Hence, the height of the parallelogram in 7in

91x-2=180

91x = 182

x = 2

Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Answers

Answer:

area = 82 cm²

Step-by-step explanation:

The figure comprises a trapezoid, a triangle and a square.

Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.

Area of square : (side)²

= (2)²

= 4 cm²

Area of triangle : ½ × b × h

= ½ × 3 × 12

= 3 × 6

= 18 cm²

Area of trapezoid : ½ × (a + b) × h

= ½ × (5+5) × 12

= ½ × 10 × 12

= 5 × 12

= 60 cm²

Now, area of the composite figure :

= 4 + 18 + 60

= 22 + 60

= 82 cm²

Answer:

82 cm²

Step-by-step explanation:

If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.

Its area is:

A = (5 + 8)*12/2 = 78 cm²

Add the area of the square with sides of 2 cm:

A = 2*2 = 4 cm²

Total area is:

A = 78 + 4 = 82 cm²
