Different names are written onto sticks and placed into a cup. A
stick is chosen 100 times, out of which Lyla's name is chosen 23
times. Based on the results, how many times should Lyla expect her
name to be drawn if 320 sticks are drawn?

Answers

Answer 1

Answer:

73.6 (or actually 74 - you can't have 0.6 times)

Step-by-step explanation:

here, you're effectively just multiplying fractions.

it is 23/100 that were drawn but 320 is 3.2 X 100 so all you have to do is multiply 23 by 3.2 which is 73.6

Solve the equation by factoring. z2 – 6z – 27 = 0

z = –3 or z = 9
z = –3 or z = –9
z = 3 or z = –9
z = 3 or z = 9

Answers

Answer:

The value of z = -3 or z = 9

Step-by-step explanation:

Given equation => z² – 6z – 27 = 0

=> z² - 9z + 3z - 27 = 0

=> z(z -9 ) +3 (z - 9 ) = 0

=> (z + 3) (z - 9)

=> z = -3 or z = 9

A pyramid has a square base that has an area of 144 square feet. If the slant height of each triangular face is 10 in, what is the total surface area of the pyramid?

Answers

Answer:

Total Surface Area

= 384 sq ft

Step-by-step explanation:

To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.

Area of square base is given.

A = 144 sq ft

Since the base is a square the length of the side of the square is 12, because 12×12 is 144.

The side of the square base is the base of the triangular side.

Area of a triangle:

A = 1/2•b•h

A = 1/2(12)(10)

A = 60

The area of one triangular face is 60. There are four of these.

A = 4(60)

A = 240

This is the area of all the triangular faces.

Add them all up.

A (TOTAL)

= 144+240

= 384 sq ft

Answer:

(a)  graph iii)

(b)  graph v)

(c)  graph ii)

(d)  graph iv)

Step-by-step explanation:

All given equations are in vertex form:  y = (x - h)² + k

where (h, k) is the vertex of the parabola

The vertex is the turning point of the parabola, so the minimum point for parabolas that open upward, and the maximum point for parabolas that open downward.

Vertices of the given graphs:

i) (-3, 2)

ii) (-3, -2)

iii) (2, 3)

iv) (3, 2)

v) (-2, -3)

vi) (2, -3)

Part (a)

Given equation:  y = (x - 2)² + 3

Therefore, the vertex is (2, 3) → graph iii)

Part (b)

Given equation:  y = (x + 2)² - 3

Therefore, the vertex is (-2, -3) → graph v)

Part (c)

Given equation:  y = (x + 3)² - 2

Therefore, the vertex is (-3, -2) → graph ii)

Part (d)

Given equation:  y = (x - 3)² + 2

Therefore, the vertex is (3, 2) → graph iv)

Vertex form of parabola having vertex (h,k)

y=a(x-h)²+k

#1

y=a(x-2)²+3

Vertex (2,3)

Luke and Ella have money in their bank account in the ratio 7:8

Luke gives £2 to Ella, and the ratio becomes 4:5.

Work out the original amount of money that Ella had.

Answers

Answer:

$48

Step-by-step explanation:

Ratios can be written as fractions.

1) Initially, Luke had 7x money, Ella had 8x money. Luke gives $2 to Ella. So, Luke now has 7x - 2 money and Ella has 8x + 2. The total amount of money is 4:5. These could be shown as fractions.

7x - 2/8x + 2 = 4/5

4(8x + 2) = 5(7x - 2)

32x + 8 = 35x - 10

8 + 10 = 35x - 32x

18 = 3x

18/3 = x

x = 6

2) Substitute the result (x = 6) into 7x:8x.

= 7(6)

= 42

= 8(6)

= 48

A cuboid with a volume of 374cm^3 has dimensions 2cm,(x+3)cm and (x+9)cm
Please help me get the full 7 marks

Answers

Answer:

x² + 12x - 160 = 0

x = 8 or x = -20

The dimensions are 2 cm, 11 cm, 17 cm.

Step-by-step explanation:

The volume of the cuboid is the product of the three dimensions.

volume = 2(x + 3)(x + 9)

volume = 2(x² + 12x + 27)

volume = 2x² + 24x + 54

We are told the volume equals 374 cm³.

2x² + 24x + 54 = 374

2x² + 24x - 320 = 0

x² + 12x - 160 = 0

(x - 8)(x + 20) = 0

x - 8 = 0 or x + 20 = 0

x = 8 or x = -20

We do not use x = -20 because it would cause two dimensions to be negative which cannot be.

x = 8

x + 3 = 8 + 3 = 11

x + 9 = 8 + 9 = 17

The dimensions are 2 cm, 11 cm, 17 cm.
