If 4g^2 -1= 16h^2 -1, what is the value of g in terms of h?<br> Plz explain

ale4655 [162]

Answer:

g = ±2h

Step-by-step explanation:

4g^2 -1= 16h^2 -1

Add 1 to each side

4g^2 -1+1= 16h^2 -1+1

4g^2 = 16h^2

Divide each side by 4

4/4g^2 = 16/4h^2

g^2 = 4 h^2

Take the square root of each side

sqrt(g^2) = ±sqrt(4h^2)

g = ±sqrt(4h^2)

g = ±2h

e 400 trials in which the assistant maintained a neutral expression, the driver stopped in 229 out of the 400 trials. Find a 95%

Fittoniya [83]

Answer:

Step-by-step explanation:

n = 400

Proportion p = 229/400= 0.5725

For 95% confidence interval we use Z value as 1.96

Std error = 0.025

margin of error = 1.96*0.025

Confidence interval 95% = 0.5725±Margin of error

= (0.524, 0.621)

b) When smiled x becomes 277

p = 0.6925

Std error = 0.023

Margin of error= 1.96*0.023

Confidence interval = (0.647, 0.738)

Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.

Determine the number of solutions: 6x-2=x+13

Finger [1]

Answer: B) one solution

Reason: if we solve for the sides of the equation by putting like terms together we get that x = 3

There is no solution when the numbers don’t equal each other, take for instance 1 = 2

It has infinite solutions when the numbers are equal to each other like
1 = 1

It has one solution when the x value is equal to something like x = 9

I also worked out the equation on paper, so you could get a more visual way of how I solved it.

Hope this helps
