Answer:

A. 12375

Step-by-step explanation:

Simple Interest Formula:

[tex]A = P(1+rt)\\[/tex]

A = 37375 in this case. This is the amount of money you'll have after 9 years. However, the question asks for how much interest you'll gain, meaning you have to subtract the principle from it. 37375 - 25000 =  12375

The area of a circle with a radius of 1.2 meters is 4.5 m², rounded to two significant figures to match the precision of the given radius.

The area of a circle is given by the formula A = πr², where π (pi) represents a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. When calculating the area with a radius of 1.2 meters, we get the precise calculation as A = π(1.2 m)² = 4.5238934 m². However, as the radius is given with only two significant figures, the area should also be rounded to two significant figures, resulting in A=4.5 m².

The sequence is an illustration of a geometric sequence

The recursive formula of the sequence is [tex]\mathbf{a_n = 40 \times 0.75^{n-1}}[/tex]

The sequence is given as: 40, 30, 22.5.....

So, we have:

[tex]\mathbf{a_1 = 40}[/tex]

[tex]\mathbf{a_2 = 30}[/tex]

[tex]\mathbf{a_3 = 22.5}[/tex]

Rewrite as:

[tex]\mathbf{a_1 = 40}[/tex]

[tex]\mathbf{a_2 = 40 \times 0.75}[/tex]

[tex]\mathbf{a_3 = 40 \times 0.75^2}[/tex]

Express 2 as 3 - 1

[tex]\mathbf{a_3 = 40 \times 0.75^{3-1}}[/tex]

Substitute n for 3

[tex]\mathbf{a_n = 40 \times 0.75^{n-1}}[/tex]

Hence, the recursive formula is [tex]\mathbf{a_n = 40 \times 0.75^{n-1}}[/tex]

Step-by-step explanation:

Answer:

1)Mean=920 $

2)Standard Error =S.E.=38

3)more likely to take place Event 25 studio apartments with a mean rent between $901 and $939

Step-by-step explanation:

Given:

True mean =920 $

S.D=190 $

No .of samples=25

To Find:

1)Mean of sample.

2)S.E

Solution:

Now , the mean for given sample distribution is  given as 920 $

Hence Mean =920 $

Now calculating the Standard error

S.E.= S.D./Sqrt(n)

=190/Sqrt(25)

=190/5

=38

Therefore the Standard error is about 38 .

a) When n=1 then P(901≤X≤939)

So,

Z1=(901 -920)/190/Sqrt(1)]

Z1=-0.1

Z2=(939-920)/(190/Sqrt(1)]

Z2=0.1

So

Pr(-0.1≤Z≤0.1)=P(Z≤0.1)-P(Z≤-0.1)

=0.5398-0.4602

=0.0797  % chance of the sample distribution

b)n=25 then P(901≤X≤939)

Z1=(901-920)/S.E

Z1=-19/38=

Z1=-0.5

And Z2=0.5

So,

Pr(-0.5≤Z≤0.5)

=Pr(Z≤0.5)-Pr(Z≤-0.5)

=0.6915-0.3085

=0.3829

i.e 38.29 % chance of the sample distribution

Hence More likely to take place will be a sample of 25 studio apartments with a mean rent between $901 and $939.

0.3829>0.0797.

Because the probability of causing above event is more than the option A.

The 1000 cubic centimeters of aluminium is enough for aluminium a trophy  that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.

Step-by-step explanation:

The given is,

                    Volume of aluminium available is 1000 cubic centimeters

                    Shape of trophy is right square pyramid

                    Trophy has a base edge of 10 cm and slant height of 13 cm

Step:1

                     Formula for volume of right square pyramid,

                                               [tex]Volume, V = a^{2}\frac{h}{3}[/tex].....................................(1)

                     Where, a - Base edge value

                                  h - Height of pyramid

                      From given,

                                        a = 10 cm

                                        h = 13 cm

                      Equation (1) becomes,

                                           [tex]= 10^{2}(\frac{13}{3} )[/tex]

                                           [tex]= (100)(4.333)[/tex]

                                           [tex]= 433.33 cm^{3}[/tex]

             Volume of trophy = 433.33 cubic centimeters

             Compare with the volume of available aluminium and volume of right square pyramid,                          

            [tex]Volume of available aluminium > Volume of right square pyramid[/tex]

                                               [tex]1000 cm^{3} > 433.33 cm^{3}[/tex]

            So, the given volume of aluminium is enough to make right square pyramid shaped trophy.

The problem involves finding the surface area of a sphere using its circumference. This can be achieved by first calculating the radius from the given circumference, and then substituting  this value into the formula for the surface area of a sphere.

The subject for this problem is finding the surface area of a sphere using its circumference. To solve this, you need to apply some mathematical concepts and formulas related to spheres and circles. The circumference of a circle (or the widest circle in a sphere, in this case) is given by

C=2πR, where R is the radius of the circle.

So, first, you need to find the radius of the sphere from the given circumference:

540.08 = 2πR, solve this to get R = 540.08 / (2*3.14).

According to the formula for the surface area of a sphere A=4πR²,

we can substitute the value of R that we have calculated to find the surface area of the sphere.

Algebra I

Step-by-step explanation:

We are given the line y = 6, a horizontal line with a slope of 0.

According to the answer choices, we need to find an equation of a line that also has a slope of 0.

A, B, and D are all incorrect, as they have a different slopes than the original line (Slope of -6, undefined, and 6 respectively).

Therefore, our only option is C, which is the correct answer.

y = 1 has the same slope, a slope of 0. However, it has a different y-intercept, a y-intercept of 1 compared to the original y-intercept 6. They are parallel and will never intersect.

Measure of arc AE = 58°

Step-by-step explanation:

As shown: ABCD is a quadrilateral, ∠C = 119°

So, ∠C + ∠A = 180°

∴ ∠A = 180° - ∠C = 180° - 119° = 61°

ΔAGB is a right triangle at G

So, ∠A + ∠B = 90°

∴ ∠ABG = 90 - ∠A = 90 - 61 = 29°

Arc AE opposite to the angle ∠ABG

So, measure of arc AE = 2∠ABG = 2 * 29° = 58°

Step-by-step explanation:

Add 5 to both sides

x + 5 = 5 - 5

x + 5  = 0

and

x = 7

Subtract 7 from both sides

x - 7 = 7 - 7

x - 7 = 0

(x + 5)(x - 7) =0

x^2 -7x + 5x -35 =0

x^2 -2x -35 = 0
