Answer:

payment: $413.93
total repaid: $74,507.40
interest: $22,507.40

Step-by-step explanation:

(a) The monthly payment A on principal P at monthly rate r for n months can be computed using ...

A = Pr/(1 -(1+r)^-n)

For P=$52000, r = .051/12 = 0.00425, n = 12*15 = 180, the payment is ...

A = $52000·0.00425/(1 -1.00425^-180) ≈ $413.93

(b) The total of 180 payments is ...

180 · $413.93 = $74,507.40

(c) The difference from the principal is the interest paid:

$74,507.40 -52,000 = $22,507.40

Answer:

$p=36^{\circ}$

Step-by-step explanation:

We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is $90^{\circ}$ .

Because all the angles of a triangle sum to $180^{\circ}$ , we have that $p+54+90=180$ .

We combine like terms on the left side to get $p+144=180$ .

We subtract $144$ on both sides to get $p=36$ .

So, $\boxed{p=36^{\circ}}$ and we're done!

How to find the circumference of a circle that is 42m and has diameter

Nitella [24]

Answer:

Circumference of the circle is $131.88m$

Step-by-step explanation:

we have to find the circumference of the given circle.

Given:

Diameter=42 m

$\\diameter=2*radius\\42 =2*radius\\radius=42/2\\radius=21 m$

Circumference of a circle= $2\pi r$

$=2*\pi *21\\=2*3.14*21\\=42*3.14\\=131.88$

So, the circumference of the circle is $131.88m$

Exercise 3.62. A little boy plays outside in the yard. On his own he would come back inside at a random time uniformly distribut

PtichkaEL [24]

Answer:

0.38

−0.0814

Step-by-step explanation:

X ___ 0 __ 0.15 __ 0.30 ___ 0.45 ___ 1

P(x)_0.20 _0.20___0.20 ___0.25 __0.20

The expected mean ; E(X) :

Σx * p(x)

(0*0.2) + (0.15*0.2) + (0.3*0.2) + (0.45*0.2) + (1*0.2) = 0.38

The variance ; Var(X) :

Σx²*p(x) - E(x)²

(0^2 * 0.2) + (0.15^2 * 0.2) + (0.3^2 * 0.2) + (0.45^2 * 0.2) + (1*0.2) - 0.38^2

0.063 - 0.1444
