Step-by-step explanation:
Dada la siguiente información:
Costo total= $1,956
<u>Para calculate el valor parcial, debemos usar la siguiente información:</u>
Precio proporcional= costo total* ( 1 - porcentaje de descuento)
50%:
Precio proporcional= 1,956*(1 - 0.5)
Precio proporcional= $978
25%:
Precio proporcional= 1,956*(1 - 0.75)
Precio proporcional= $489
Answer:
140+d = 192
d = 52
Step-by-step explanation:
the weight of the vet plus the god = total weight

d = 192 - 140
d = 52
To solving with their equation and expression to step by step.
3b/a-2
= -2a+3b/a
For every 1,000 feet you go up in elevation, the temperature decreases by about 3.3°F
Given:
Temperature at the bottom of the mountain is 74°F
The top of the mountain is 5500 feet above you
Change (reduction) in temperature is 3.3 X 5500 / 1000
= 18.15°F
Temperature at the top of the mountain is 74°F – 18.15°F
= 55.85°F
Answer: 0.5467
Step-by-step explanation:
We assume that the test scores for adults are normally distributed with
Mean :
Standard deviation :
Sample size : = 50
Let x be the random variable that represents the IQ test scores for adults.
Z-score :
For x =85
For x =115
By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-
Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
