Write the Inequality

A number b times -16 is greater than 5.

A number b is a variable... b.

Times means multiply.

-16 is what you are multiplying b by.

Is greater than means the greater than symbol.

5 is what the past statements are greater than.

So this is the inequality.

-16b > 5

Solve the Inequality

You need to isolate b.

To do this, divide each side by -16. You do this because b is being multiplied by -16. You know that any number divided by that number equals 1, canceling the number.

-16b ÷ -16 = b

5 ÷ -16 = -5/16

So you get b > -5/16

So to make the inequality true, b must be more than -5/16.

Or as an inequality...

b > -5/16

What is the result of adding these two equation?<br> 5x-9y=1<br> -7x+2y=-5

SCORPION-xisa [38]

The result of adding the given equations is 2x+7y=4.

Step-by-step explanation:

Given equations are;

5x-9y=1 Eqn 1

-7x+2y=-5 Eqn 2

Adding Eqn 1 and 2

$(5x-9y)+(-7x+2y)=1+(-5)\\5x-9y-7x+2y=1-5$

Arranging alike terms;

$5x-7x-9y+2y=-4\\-2x-7y=-4$

Dividing each term by -1

$\frac{-2x}{-1}+\frac{-7y}{-1}=\frac{-4}{-1}\\2x+7y=4$

The result of adding the given equations is 2x+7y=4.

inspection of a random sample of 25 aircraft showed that 17 needed repairs to fix a wiring problem that might compromise safety.

lora16 [44]

The random sample proportion:

at 90% confidence interval: The Central 90% of any normal distribution is: Z_(α/2) = 1.960

Error = E = ±5% = ±0.05

Applying the normal distribution theory,

= 0.70 ≤ P≤ 0.77(this means that we are 90% confident that the true proportion of jet with wiring problem fall with 0.70 and 0.77, hence there is no need for the airline to conduct further sampling, rather, they should just inspect all the planes)
