A student scores 88,73,81,75, and 78 on the first five science tests of the year. What is the minimum score the student needs to
NeTakaya

Answer:84

Step-by-step explanation: add all the numbers together you should get a total of 395

Step 2 divide 395 by 5 = 79 that’s your average so far

Step 3 ( x the 6th test)

5• 79 + x =80 You will first multiply

6 5•79 = 395

Then 80 • 6 =480

Then subtract 480-395 = 85 is the lowest you will need to make

In an effort to cut costs and improve profits, any US companies have been turning to outsourcing. In fact, according to Purchasi
tangare [24]

Answer:

Step-by-step explanation:

This is a binomial probability distribution because there re only 2 possible outcomes. It is either a surveyed company outsourced some part of their manufacturing process in the past two to three years. The probability of success, p would be that a randomly selected company x, outsourced some part of their manufacturing process in the past two to three years. From the information given, p = 54/100 = 0.54

Number of success, x = 338

Number of samples, n = 555

We want to determine the probability that 338 or more companies outsourced some part of their manufacturing process in the past two or three years which is expressed as

P(x ≥ 338)

From the binomial probability calculator,

P(x ≥ 338) = 0.0006

The percentage is 0.0006 × 100 = 0.06%

Answer:

A quadratic equation can be solved using the quadratic formula, the factoring method, or completing the square. You expect to get either one or two answers.

Step-by-step explanation:

First, we have to understand how to solve a quadratic equation. There are three methods, the first of which is the quadratic formula. For any quadratic equation that takes the standard form of

f(x)=ax^2+bx+c

you can solve for x by using the following formula:

x=(-b±√(b^2-4ac))/2a

Sometimes, however, the quadratic expression is factorable, meaning it can be converted into a product of two smaller expressions. For example:

x^2-4=(x-2)(x+2)

As you can see, factoring gives you the roots easily (set each smaller expression to 0 and solve for x). If the quadratic is factorable, it would be easiest to use this method first.

Completing the square is another method that can be used to solve a quadratic function. It is often preferred because it converts the function into something factorable. In order to complete the square, you have to first ensure that the quadratic term's coefficient is 1. After that, you can take the linear term's coefficient, divide it by 2, and square it. Take the new term you found and add it to the equation. Because you are adding something to an equation, you must also subtract. Now, you can complete the square and factor. An example can be found below:

x^{2}-6=0\\\\(x^2-6+9)-9=0\\\\(x-3)^2-9=0\\\\(x-3-3)(x-3+3)=0\\\\x(x-6)=0\\\\x=0, x=6

A quadratic equation can only have up to two solutions. You can imagine the graph of a quadratic. It looks like a parabola and only changes directions once. This means that it only crosses the x-axis two times. You can also look at the examples given and see that factoring only gives you two smaller expressions (leading to 2 roots). Sometimes, however, you might get a double root, leading to an equation with only one solution. This happens when the discriminant of the quadratic equation is 0. You can calculate this in advance to save yourself some time.

Next month, Noelle will earn a 15% increase in her hourly wage. If she currently earns $12 an hour, what will her new hourly wag
Bad White [126]

Answer:

<em>Her new hourly wage will be $13.80 after the raise</em>

Step-by-step explanation:

<u>Percentages</u>

Noelle currently earns $12 per hour.

Her hourly wage will increase by 15% by next month.

The increase will be of:

15% of $12 = 15*12/100 = $1.80

Thus, her new hourly wage will be

$12 + $1.80 = $13.80

Her new hourly wage will be $13.80 after the raise
