Answer:

Choose every tenth student entering the school and ask them if they like the dress code or not.

Step-by-step explanation:

This is a question of sampling. We need to make non-biased predictions using non-biased data. We can sample from every tenth student to stay proportional. Sampling many students can collect more data and can help keep the data non-biased.

A person invested $6,000, some at 7% and the rest at 5%. The income from the 7% investment is equal to the income from the 5% in

8090 [49]

Answer:

The person invested $3500 at 7% and $2500 at 5%

Step-by-step explanation:

We can say that $0,07x+0,05x=6000$ because the investment is equal both in one as in another, where x is the income from the investment.

Solving the equation we have:

$0,12x=6000\\x=50000$

Then to get the incomes:

At 7%: $I=0.07*50000\\I=$3500$

And at 5%: $I=0.05*50000\\I=$2500$

Finally we can demonstrate the answer because the income at 7% + income at 5% are 3500+2500=$6000

Write a slope-intercept equation for a line perpendicular to f(x) = −2x + 4 and

Fittoniya [83]

Answer:

$y = \frac{1}{2} x + 1$

Step-by-step explanation:

<u>Slope-intercept form</u>

y= mx +c, where m is the slope and c is the y-intercept

f(x)= -2x +4

Let's rewrite this function into an equation, in the slope-intercept form.

y= -2x +4

Slope= -2

The product of the slopes of perpendicular lines is -1.

Let the slope of the perpendicular line be m.

m(-2)= -1

m= ½

y= ½x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -4, y= -1,

-1= ½(-4) +c

-1= -2 +c

c= -1 +2

c= 1

Thus, the equation of the line is y= ½x +1.
