Are the equations -2x=10 and -5x=25 equivalent

Natasha_Volkova [10]

To equations are equivalent if and only if they have the same solution set.

Solve for both of the equations.

-2x = 10
x = -5 <-- Divide both sides by -2

-5x = 25
x = -5 <-- Divide both sides by -5

Both have the solution -5.

So, yes both are equivalent.

the total attendance at a concert in a theater hall was 1500, of this total 400 were children,850 were women , and the remaining

AleksandrR [38]

Answer:

Below!

Step-by step explanation:

We know that:

400 + 850 + m = 1500

Solution of Question A:

Percent of children: Total children/Total attendance

=> 400/1500
=> 4/15
=> 0.27 (Rounded to nearest hundredth)
=> 0.27 x 100
=> 27%

Hence, the percent of children is about 27%.

Solution of Question B:

Percent of women: Total women/Total attendance

=> 850/1500
=> 85/150
=> 17/30
=> 17/30 x 100
=> 17/3 x 10
=> 170/3
=> 56.67%

Hence, the percent of women is 56.67%.

Solution of Question C:

400 + 850 + m = 1500
=> 1250 + m = 1500
=> m = 1500 - 1250
=> m = 250

Percent of men: Total men/Total attendance

=> 250/1500
=> 1/6
=> 0.17 (Rounded to nearest hundredth)
=> 0.17 x 100
=> 17%

Hence, the percent of men is about 17%

Hoped this helped.

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type y

Virty [35]

Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%
