How could you give someone £63 using SIX notes or coins, WITHOUT using any coin under £2 ? (You can’t use £1, 50p, 20p, 10p, 5p, 2p, 1p)

Answer:

A is right.  domain = {112, 120, 128, 136, 144}

Step-by-step explanation:

The range is the y-coordinate while the domain is the x-coordinate

y = x/4

x = 4y

domain = {4(28), 4(30), 4(32), 4(34), 4(36)}

= {112, 120, 128, 136, 144}

Answer: x=14

Step-by-step explanation: The total is 180 degrees. The right angle is 90, the given angle is 76, so x is 14.

Answer:

The quotient will be around 7

Step-by-step explanation:

Compatible numbers in division, refers to numbers that can be divided mentally.

27 + 2/3 ÷ 3 + 9/10

27 + 0.67 ÷ 3 + 0.9

27.67 ÷ 3.9

Approximately

28 ÷ 4

=7

Answer:

the sample response is-

The first fraction is between 27 and 28, closer to 28. The second fraction is between 3 and 4, closer to 4. Compatible numbers in division are numbers that can be divided mentally. 28 divided by 4 is 7. The quotient will be around 7.

Step-by-step explanation:

The line of the best fit is y = 0.5x + 2.4 if the Marisol recorded the height (in centimeters) of a pea plant over a 10-day period for a science experiment option (C) is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the equation of the best fit is:

y = mx + b

[tex]\rm m = \dfrac{n \sum xy-\sum x \sum y}{n \sum x^2-(\sum x)^2}[/tex]

[tex]\rm b = \dfrac{\sum y -m \sum x}{n}[/tex]

After calculating, we get (refer table)

m = 0.48 ≈ 0.5

b = 2.4

y = 0.5x + 2.4

Thus, the line of the best fit is y = 0.5x + 2.4 if the Marisol recorded the height (in centimeters) of a pea plant over a 10-day period for a science experiment option (C) is correct.

Answer:

3times

Step-by-step explanation:

Baking Process: repeatedly rolling out and folding the dough to make layers

Soon Yi starts with a layer of dough = 2millimeters

Each time Soon Yi rolls and folds the dough, the thickness increases by 8 % = 1 + 8 %

When time = 1

Thickness = 2(1 + 8 %) = 2(1+0.08)

= 2(1.08) = 2.16

For time = n

Thickness = 2(1 + 8 %)^n = 2(1.08)^n

When thickness ≥ 2.5mm, n= ?

2.5 = 2(1.08)^n

2.5/2 = (1.08)^n

1.25 = (1.08)^n

Since the numbers are close (1.25 and 1.08), we can compute by multiplying 1.08 by itself till we get 2.5.

1.08 ×1.08× 1.08 = 1.259712

(1.08)³ is a bit above 1.25

2(1.08)³ satisfies the thickness of at least 2.5mm

Let's check our answer using the formula:

When n = 3

2(1.08)³ = 2 × 1.259712 = 2.519424

This satisfies the thickness of at least 2.5mm

Therefore, the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5 mm = 3

Answer:

D. 0.85

Step-by-step explanation:

Given

Probability of S = 0.8

Probability of R = 0.7

Probability of S and R = 0.65

Required

Probability of S or R

Using probability notations;

P(S) = 0.8

P(R) = 0.7

P(S n R) = 0.65

The question requires that we solve for P(S or R)

For overlapping events S and R; the following formula is applicable.

P(S or R) = P(S) + P(R) - P(S n R)

Substitute the values of P(S), P(R) and P(S n R)

P(S or R) = 0.8 + 0.7 - 0.65

P(S or R) = 0.85

Hence, the probability that either a rec team or a school team has a game is 0.85

Answer: C. [tex] (2, \sqrt{5}) [/tex]

Step-by-step explanation:

The x coordinate is 2, which is 2 units right of (0, 0)

- √5 is the y coordinate

- (√5) = - (2.23) = -2.23

The y coordinate is -2.23 or 2.23 down from (0, 0)

The rest of the ordered pairs are slightly off the edge of the circle.

Answer: - 4

Step-by-step explanation:

Given that A = - 4, B = 3

According to the instruction :

Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3

Raise - 2 to the double of b ;

Result = (-2)^(2*3) = (-2)^6 = 64

Divide result by quadruple of a

a = - 4 ;

Quadruple of 'a' means 4 times as many as 'a' = '4 * a' quadruple of a = (-4) * 4 = - 16

= (-2)^6 / -16

64 / - 16

64 / - 16 = - 4

Answer:

90

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

9x+9 = 45+5x

Subtract 5x from each side

9x-5x+9 = 45+5x-5x

4x+9 = 45

Subtract 9 from each side

4x+9-9 = 45-9

4x = 36

Divide by 4

4x/4 = 36/4

x = 9

The exterior angle is

9x+9

9*9+9

Hey there!

To find the volume of any prism, you multiply the base by the height. However, we want to find the base here. So, we do it backwards and take the volume and divide it by the height, and this will give us our base!

50÷7.5=6 2/3

Therefore, the area of the base of a pentagonal prism with a volume of 50 cubic centimeters and a height of 7.5 centimeters is 6 2/3 square centimeters.

Step-by-step explanation:

There are 52 cards in the deck

4 kings

P(king) = king/total = 4/52 = 1/13

replacement

52 cards , 4 queens

P(queen) = queen/total = 4/52 = 1/13

P(king, replacement, queen) = 1/13 * 1/13 =1/169

There are 52 cards in the deck

4 kings

P(king) = king/total = 4/52 = 1/13

no replacement

51 cards , 4 queens

P(queen) = queen/total = 4/51 =4/51

P(king,  no replacement, queen) = 1/13 * 4/51 =4/663

Answer:  2

Step-by-step explanation:

x⁴ - x³ + x² - x

Factor to find the zeros:

   x³(x - 1) + x(x - 1)

= (x³ + x)(x - 1)

= x(x² + 1)(x - 1)

Zeros are: x = 0,   x = ±i,   x = 1

There are two real zeros and two imaginary zeros.

The x-intercepts are the two real zeros: at x = 0 and x = 1

X-intercepts on the graph of the polynomial function

[tex]f(x) = x^{4} -x^{3} +x^{2} -x[/tex]  is 2 x-intercept.

" X- intercept is defined as the when line passes through x- axis at y = 0."

According to the question,

Given polynomial function,

[tex]f(x) = x^{4} -x^{3} +x^{2} -x[/tex]

To get x- intercept polynomial function f(x) =0 we get,

[tex]x^{4} -x^{3} +x^{2} -x = 0[/tex]

⇒[tex]x^{3} (x-1)+ x(x-1)=0[/tex]

⇒[tex](x^{3} +x)(x-1)=0[/tex]

⇒ [tex]x(x^{2} +1)(x-1)=0[/tex]

⇒ [tex]x=0 , x=1 , x=\sqrt{-1}[/tex]

Here , two possible real values are there for x-intercept x=0 and x=1.

Hence, X-intercepts on the graph of the polynomial function

[tex]f(x) = x^{4} -x^{3} +x^{2} -x[/tex]  is 2 x-intercept.

Answer:

A) P(10 on three rolls) = 1/1728 = 0.0005787

B) P(10 in two of three rolls) = 11/1728 = 0.0063657

Step-by-step explanation:

Each die has 6 possible values, so a pair of dice have a total of 6*6=36 outcomes.

To find a sum of 10, the cases are:

(4,6), (5,5) and (6,4).

So to have a sum of 10 we have 3 cases among the 36 possible, therefore the probability is:

P(10) = 3/36 = 1/12

A)

If we want the sum of 10 in each of the three rolls, the probability is:

P(10 on three rolls) = P(10)^3 = (1/12)^3 = 1/1728 = 0.0005787

B)

If the sum is 10 in two of three rolls, in one roll we need the probability of the sum not being 10:

P(not 10) = 1 - P(10) = 1 - (1/12) = 11/12

So we have:

P(10 in two of three rolls) = P(10)^2 * P(not 10) = (1/12)^2 * (11/12)

P(10 in two of three rolls) = 11/1728 = 0.0063657

Simplifying the expression (x - 2y) + (3x + 4y).

Work:

(x - 2y) + (3x + 4y)

Combine like terms.

x + 3x = 4x

-2y + 4y = 2y

Reform the expression.

4x + 2y

Simplified Expression: 4x + 2y.

Answer:

20xπ units

Step-by-step explanation:

Use the formula for the length of an arc.

θ/360 × 2πr

The length of the arc and the central angle is already given.

18/360 × 2πr = xπ

Solve for r.

r = (xπ)/(18/360)/(2π)

r = 10x

The radius of the circle is 10x.

The circumference of a circle is 2πr.

2π(10x)

20xπ

The circumference of the circle is 20xπ units.
