What is the percent change from 70 to 56

Answers

let x be the percent of change

70-70x=56

-70x=56-70

-70=-14

x= -14/-70

x= 1/5

x= 20%

The percent change from 70 to 56 is 20% decrease .

I hope that's help !

The vending machine in the school cafeteria usually dispenses about 6 ounces of soft drink. Lately, it is not working properly, and the variability of how much soft drink it dispenses has been gettin greater. The amounts are normally distributed with a standard deviation of 0.2 ounces. 1. What percent of the time will you get between 5.6 and 6.4 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%

2. What percent of the time will you get between 6 ounces and 6.2 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%

Answers

#1) D, 95%
#2) B, 34%

Explanation
#1) The mean is 6 and the standard deviation is 0.2. 5.6 is 0.4 away from the mean; 0.4 is 2 standard deviations. 6.4 is 0.4 away from the mean; again, 0.4 is 2 standard deviations.

The empirical rule states that 95% of data will be within 2 standard deviations of the mean, so 95% is our answer.

#2) 6.2 is only 1 standard deviation away from the mean. However, this is only half of the percentage from the empirical rule, since we are only considering numbers larger than the mean. The empirical rule states that 68% of data will fall within 1 standard deviation from the mean, so we have
68/2 = 34%.

Final answer:

The percentage of the time you will get between 5.6 and 6.4 ounces is about 68%, closest to option (b) 34%. The percentage of the time you will get between 6 and 6.2 ounces is 34%, or option (b).

Explanation:

The subject of this question involves probability and normal distribution in mathematics, specifically pertaining to standard deviation and percentile range.

For the first question, the range you seek (5.6 to 6.4 ounces) is precisely within one standard deviation (0.2 ounces) both above and below the mean (6 ounces). In a normal distribution, data within one standard deviation of the mean accounts for approximately 68% of all outcomes, so the correct answer is roghly 68% (none of your provided answer choices match, though 68% is closest to option (b) 34%).

For the second question, the range you seek (6 to 6.2 ounces) is within 0.2 ounces above the mean. Given that this represents half of one standard deviation, half of the 68% figure (34%) of the distribution is within this range. So, the correct answer is 34%, which corresponds to option (b).

At the market, 5 light bulbs cost $9.85 How much do 7 light bulbs cost?

Answers

Divide 9.85 by 5 to get the cost of one, and that is 1.97. Then mutiply 1.97 by 7 to get the cost of 7 of them, and that is 13.79. So the answer is 13.79. Hope this helps.

Cost of one light bulb: $1.97

I found this my dividing 9.85 by 5. Next we need to multiply 1.97 by 7 to get 13.79.

Answer: 7 light bulbs cost $13.79'

Without calculating, is the equation (1.8 x 3) x 2.1 = 3 x (1.8 x 2.1) true or false? Explain your reasoning

Answers

The expression is correct because changing the place in the multiplication operation does not affect the final result.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,the equation is 1.8 x 3) x 2.1 = 3 x (1.8 x 2.1) t

L.H.S

=(1.8×3)×2.1

=5.4×2.1

=11.34

R.H.S.

=3 x (1.8 x 2.1)

=3×3.78

=11.34

L.H.S.=R.H.S.

Thus, the expression is correct because changing the place in the multiplication operation does not affect the final result.
