<span>Answer: 199.81
Given:
1 hundred
9 tens
9 ones
8 tenths
1 hundredths
thus;
1 hundred = 1 x 100 = 100
9 tens = 9 x 10 = 90
9 ones = 9 x 1 = 9
8 tenths = 8 x 1/10 = 8/10 or .8
1 hundredth = 1 x 1/100 = 1/100 or .01
add: 100 + 90 + 9 + .8 + .001 = 199.81
That is: one hundred ninety-nine and eighty-one hundredths</span>
Answer:
a) The probability that at least 5 ties are too tight is P=0.0432.
b) The probability that at most 12 ties are too tight is P=1.
Step-by-step explanation:
In this problem, we could represent the proabilities of this events with the Binomial distirbution, with parameter p=0.1 and sample size n=20.
a) We can express the probability that at least 5 ties are too tight as:

The probability that at least 5 ties are too tight is P=0.0432.
a) We can express the probability that at most 12 ties are too tight as:

The probability that at most 12 ties are too tight is P=1.
25% markup = original + 25% = 125% of original = 1.25 x original
Selling price = 1.25 x dealer price
Answer = 521.25/1.25=$417
Answer:
1.230 euros
Step-by-step explanation:
De la pregunta anterior se nos dice que:
Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.
Paso 1
Sea el porcentaje de la suma total de dinero = 100%
Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.
Dejemos que el resto esté representado por x
Por eso;
Primera parte + Segunda parte + Tercera parte = 100%
60% + 25% + x = 100%
x = 100% - (60% + 25%)
x = 100% - 85%
x = 15%
Paso 2
¿Cuánto pagó Yolanda la última vez?
La última vez = Tercera parte y esto se calcula como:
15% de 8.200 euros
= 15/100 × 8.200 euros
= 1.230 euros
Yolanda pagó 1.230 euros la última vez.
1 steak costs $9.99
2 steaks cost 2*9.99 = $19.98
This is before tax is applied
Apply the 6% tax to get
6% of 19.98 = (6/100)*19.98 = 0.06*19.98 = 1.1988
which rounds to 1.20 (rounded to the nearest penny)
The sales tax is therefore $1.20
Add this to the previous total (19.98) and we get a grand total of 19.98+1.20 = 21.18 which is the final cost (with tax included)
note: we can multiply 19.98 by the value 1.06 to get 19.98*1.06 = 21.1788 and that rounds to 21.18; so it's a different route to the second answer
