Answer: £122.4

Step-by-step explanation:

Given

The rate of interest is 4%

The principal invested is £1500

the time period is 2 years

Compound interest is given by

[tex]C.I.=P(1+r\%)^t-P[/tex]

put values

[tex]C.I.=1500(1+0.04)^2-1500\\C.I.=1500[1.04^2-1]\\C.I.=1500[1.0816-1]\\C.I.=1500\times 0.0816\\C.I.=122.4[/tex]

Therefore, interest earned is £122.4

Answer:

a) 36

b) 11:5

Step-by-step explanation;

a) let the number of cold stone cones be x

Since the initial ratio is 11:9

we have the ratio of the ice creams as;

11:9 = 44:x

11/9 = 44/x

11 * x = 9 * 44

x = (9 * 44)/11

x = 9 * 4 = 36

b) Now, from 36, we have a number of cold stones as 20

So the ratio now will be;

44:20

and that would be;

11:5

[tex](5x-3)^{2}[/tex] - (3x+1)(2x-1)

Step-by-step explanation:

Determine the area of the large square: (5x - 3)(5x - 3)

Determine the area of the small rectangle: (3x + 1)(2x -1)

Subtract the area of the small rectangle from the area of the large square to get the area of the shaded region.

Answer: 2 out of 20=2/20 but simplified 1/10 for trying to get a green marble.

Answer:

Step-by-step explanation:

There are four points here.  We look at the x-values and identify {2, 1, -2, 1].  This can be reduced to {-2, 1, 2}

Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).

Answer:

Diameter = 2.68cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference of a circle = 8.44cm

π = 3.14

r = ?

Circumference of a circle = 2πr

8.44 = 2 * 3.14 * r

8.44 = 6.28r

r = 8.44/6.28

r = 1.3439490445859

Approximately

r = 1.34

Diameter = 2r

Diameter = 2 * 1.34

Diameter = 2.68cm

Answer:

C. 6.6%

Step-by-step explanation:

The probability of an event 'A' occurring, P(A) is given by the ratio of the number of times event A occurs to the some of all possible events

Mathematically, we have;

[tex]The \ probability \ of \ an \ event = \dfrac{The \ number \ of \ the \ required \ outcome}{The \ number \ of \ all \ possible \ outcomes}[/tex]

The number of drivers involved in an accident who are above 75 years = 13,321

The total number of drivers in accidents = (10,034 + 17,173+ 35,712+ 40,322 + 40,937 + 30,355 + 17,246 + 13,321) = 205,100

A 78-year-old is in the age group of 75 and older

∴ The probability that a 78-year-old licensed driver was involved in an accident = The probability that a 75 and older year-old licensed driver was involved in an accident = 13,321/205,100 ≈ 0.06495 = 6.5%

Therefore, the best option is option C. 6.6%

Answer:

Options (1) and (3)

Step-by-step explanation:

Exterior angles of a triangle is equal to the sum of two remote interior angles of the triangle.

In triangle JMK,

∠JMF is the exterior angle and angles ∠KJM and ∠JKM are the remote interior angles.

m∠JMF = m∠KJM + ∠JKM

Therefore, Options (1) and (3) are the correct options.

Answer: [tex]\dfrac{x^2}{9}+\dfrac{y^2}{9}=1[/tex]

Step-by-step explanation:

Given

[tex]x=3\sin 2\phi\\y=3\cos 2\phi[/tex]

square and add [tex]x\ \text{and}\ y[/tex] terms i.e.

[tex]\Rightarrow x^2+y^2=[3\sin 2\phi]^2+[3\cos 2\phi]^2\\\Rightarrow x^2+y^2=9\sin ^22\phi+9\cos ^2 2\phi\\\Rightarrow x^2+y^2=9[\sin^2 2\phi +\cos^2 2\phi]\\[/tex]

Using identity [tex]\sin ^2\theta +\cos ^2 \theta =1[/tex]

[tex]\Rightarrow x^2+y^2=9\\\\\Rightarrow \dfrac{x^2}{9}+\dfrac{y^2}{9}=1[/tex]

Answer:

You need to add an image so we can see the line.

Step-by-step explanation:

The bill for a person who uses 300 kWh in a month is $40

The piecewise function of how the power company calculates the bill is given as:

b(x) = 0.150x, x < 200

b(x) = 0.10(x - 200) + 30, x >= 200

For a person who uses 300 kWh in a month, the value of x is 300.

i.e. x = 300

By comparing the domain of the piecewise function, we make use of the following function

b(x) = 0.10(x - 200) + 30, x >= 200

Remove the domain

b(x) = 0.10(x - 200) + 30

Substitute the known values in the above equation

b(300) = 0.10(300 - 200) + 30

Evaluate the difference

b(300) = 0.10(100) + 30

Evaluate the product

b(300) = 10 + 30

Evaluate the sum

b(300) = 40

Hence, the bill for a person who uses 300 kWh in a month is $40
