A family wants to purchase a house that costs $145,000. They plan to take out a $115,000 mortgage on the house and put $30,00

AysviL [449]

Answer:

A. 15-year mortgage =$141,478.20

30-year mortgage =$187,707.60

B. $46,229.40

Step-by-step explanation:

A. Calculation to Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage.

Calculation for 15-year mortgage

Cost amount to save for 15-year mortgage=$785.99*15-year*12 months

Cost amount to save for 15-year mortgage =$141,478.20

Calculation for 30-year mortgage

Cost amount to save for 30-year mortgage =$521.41*30-year*12 months

Cost amount to save for 30-year mortgage =$187,707.60

B. Calculation for How much would they save if they selected the 15-year mortgage

Using this formula

Amount to save=30-year mortgage -15-year mortgage

Let plug in the formula

Amount to save=$187,707.60-$141,478.20

Amount to save=$46,229.40

Therefore How much would they save if they selected the 15-year mortgage will be $46,229.40

John needs to buy at least 100 tiles to redecorate his bathroom. The tiles are sold in packs of 6.

AnnyKZ [126]

Answer: $n\geq17$

Step-by-step explanation:

Let n= Number of packs John needs.

Tiles in 1 pack = 6

Tiles in <em>n</em> pack = <em>6n</em>

If he needs at least 100 tiles.

then

6n ≥ 100

$\Rightarrow\ n\geq100\\\\\Rightarrow\ n\geq\dfrac{100}{6}\\\\\Rightarrow\ n\geq\dfrac{50}{3}\\\\\Rightarrow\ n\geq16.67\\\\\Rightarrow\ n\geq 17$

The required inequality: $n\geq17$

belka [17]

Answer:

0.195

Step-by-step explanation:

Given:

For ; sample size, n = 9 ;

Standard Error (S. E) = 0.39

S. E = σ / sqrt(n)

σ = standard deviation

0.39 = σ / sqrt(9)

σ = 0.39 * 3

σ = 1.17

Therefore, For n = 36

S. E = 1.17 / sqrt(36)

S.E = 1.17 / 6

S.E = 0.195

El equipo de béisbol de los Gatos Salvajes de Ludlow, un equipo de las ligas menores de la organización de los Indios de Clevela

mario62 [17]

Answer:

0.5645

Step-by-step explanation:

De la pregunta anterior, se nos dan los siguientes valores para el equipo de Ludlow

Probabilidad de jugar de noche = 70% = 0.7

Probabilidad de ganar en la noche = 50% = 0.5

Probabilidad de jugar durante el día = 30% = 0.3

Probabilidad de ganar durante el día = 90% = 0.9

Probabilidad de que cuando ganaron ayer, el juego se jugó por la noche =

(Probabilidad de jugar de noche × Probabilidad de ganar de noche) ÷ [(Probabilidad de jugar de noche × Probabilidad de ganar de noche) + (Probabilidad de jugar de día × Probabilidad de ganar de día)]

Probabilidad de que cuando ganaron ayer, el juego se jugó de noche = (0.5 × 0.7) ÷ (0.5 × 0.7) + (0.9 × 0.3)

= 0.35 ÷ 0.35 + 0.27

= 0.35 ÷ 0.62

= 0.5645

La probabilidad de que el partido se haya jugado de noche = 0.5645
