Answer:

About 3%

Step-by-step explanation:

It decreased.

3% of 465056=13951

465056-13951=451105

3.6% of 465056=16742

465056-16742=448314

The amount you want it 450678 and 451105 is closer to 450678 than 448314.

According to a certain country’s department of education, 40.0% of 3-year-olds are enrolled in day care.

vladimir1956 [14]

Given parameters:

Percentage of enrollment of 3-year-olds = 40%

Unknown:

Probability that a randomly selected 3-year-old is enrolled in a day care = ?

Probability is the likelihood of an event to occur.

Probability = $\frac{Possible outcome}{Total out come}$

In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.

We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.

The possible enrollment is 40 and the total is 100;

Input the parameters and solve;

Probability = $\frac{40}{100}$ = $\frac{2}{5}$

The probability that any randomly selected 3 year old is enrolled in day care is $\frac{2}{5}$

Jill would like an increase in the hourly wage she receives from the Mathematics Research Center, where she works in the mail ro

attashe74 [19]

Answer:

<em>Her raise per hour is $3.</em>

Step-by-step explanation:

<u>Quadratic Equation</u>

The standard representation of a quadratic equation is:

$ax^2+bx+c=0$

where a,b, and c are constants.

It can be solved by using the quadratic formula:

$\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Jill asks for an increase in the hourly wage she receives. Since she works in a Maths Center, the increase comes as a maths equation.

She must solve the equation:

$x^2-6x+9=0$

The solution to the equation is the increase in her hourly wage.

Comparing with the general form, we have a=1, b=-6, c=9. Thus, the solutions are:

$\displaystyle x=\frac{-(-6)\pm \sqrt{(-6)^2-4(1)(9)}}{2(1)}$

$\displaystyle x=\frac{6\pm \sqrt{36-36}}{2}$

$\displaystyle x=\frac{6\pm \sqrt{0}}{2}$

Since the square root is 0, there is only one solution:

$\displaystyle x=\frac{6}{2}=3$

x = 3

Thus, her raise per hour is $3.

Answer: D: -2
explanation:
1. divide fractions inside brackets by multiplying by the reciprocal
1/4 • 4/7
= 4/28
2. multiply 4/28 by 7/5
= 28/140 which can be reduced to 1/5
3. multiply by -10
= 1/5 • -10
= -2
