4-8=3-n\5 what is the answer?

What is the final amount if 1584 is decreased by 18% followed by a 19% increase?

Oksi-84 [34.3K]

Answer:

$1,545.67$

Step-by-step explanation:

step 1

if 1,584 is decreased by 18%

we know that

$100\%-18\%=82\%=82/100=0.82$

Multiply the number by 0.82

$1,584(0.82)=1,298.88$

step 2

The number 1,298.88 is increased by a 19%

we know that

$100\%+19\%=119\%=119/100=1.19$

Multiply the number by 1.19

$1,298.88(1.19)=1,545.67$

Use the graph to complete the following. The probability that a boxer weighs between 60 and 80 pounds is %

AlexFokin [52]

Answer:

95%

Step-by-step explanation:

The Empirical rule, also the 68–95–99.7 rule, states that for a population that is approximately normal or symmetrical, nearly all of the data values will lie within three standard deviations of the mean;

68% of data values will fall within one standard deviation from the mean

95% of data values will fall within two standard deviation from the mean

99.7% of data values will fall within three standard deviation from the mean

From the graph given, we note that the weights 60 and 80 pounds fall within two standard deviations from the mean;

70 ± (2*5) = 70 ± 10 = (60, 80)

70 is the mean, 5 the standard deviation and 2 the number of standard deviations from the mean. From the Empirical rule we can conclude that the probability that a boxer weighs between 60 and 80 pounds is 95%

Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance

alexgriva [62]

Answer:

96.512 °F < x < 591.242 °F

Step-by-step explanation:

We are given;

Melting point = 35.84 °C

Boiling point = 310.69 °C

Now, we are given that formula to convert °C to °F is;

°C = (5/9)°F

Thus if the temperature in Fahrenheit is x, then;

Melting point is; 35.84 °C = (5/9)x°F - "32"

x = ((9 × 35.84)/5) + 32

x = 96.512 °F

Similarly, for Boiling point;

Boiling point is;

310.69 °C = (5/9)x°F - "32"

x = ((9 × 310.69)/5) + 32

x = 591.242 °F

Now, we are told that matter is in its liquid form when it is between melting and boiling point.

Thus, range of x in inequality form is;

96.512 °F < x < 591.242 °F
