Answer:

542

Step-by-step explanation:

So X is the number of finals graded by teacher last year

she graded 83 more finals than the last year

and the total number of finals she graded this year is 625 so we have an equation

X + 83 = 625

and as you solve it for X

X = 625-83

x = 542

Answer:

542,

Step-by-step explanation:

You could solve these types of problems with inverse operations, so if you subtract 83 from 625, you'd get 542.

Answer:

24

Step-by-step explanation:

the question translates to asking how many times does 7/8 fit in 21, so 21 divided by 7/8.

when we divide by a fraction, we can multiply by it's inverse, so 21 divided by 7/8, is 21 multiplied by 8/7. so:

21×8/7 = (21×8)/7 = (21/7)×8 = 3×8 = 24

Answer:

The solution is 4 - 9/(2x + 1)

No, the divisor does not evenly divide into the dividend

If Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = PRT

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Sasha's bank account earns 4% simple interest. Therefore, if she wants it to be worth $1,000 in 5 years then the principal amount must be,

Account balance = PRT + P

$1,000 = P[(0.04×5)+1]

$1,000 = 1.2 P

P = $833.34

Hence, if Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.

Based on the statistics from the worldwide health organization, the percentage change in those living with the disease is 19.7% and the change in those who have died is 70%.

This shows that the disease is getting worse and not being treated effectively.

Answer:

y = 2x + 6

Step-by-step explanation:

We are given that a line runs through the points (-4,-2) and (-2,2).

We want to write the equation of this line in slope-intercept form.

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name.

First, we need to find the slope of the line.

The slope can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

Even though we have two points, let's label the values of the points to avoid confusion & mistakes.

[tex]x_1=-4\\y_1=-2\\x_2=-2\\y_2=2[/tex]

Now let's find the slope (remember: the formula has subtraction):

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{2--2}{-2--4}[/tex]

This can be simplified:

m=[tex]\frac{2+2}{-2+4}[/tex]

Add the numbers together.

m=[tex]\frac{4}{2}[/tex]

Divide.

m = 2

The slope of the line is 2.

We can substitute this into the equation for m.

Here is the equation of the line so far:

y = 2x + b

We now need to find b.

As the equation passes through both (-4, -2) and (-2, 2), we can use either one of them to help solve for b.

Taking (-4, -2) for instance:

Substitute -4 as x and -2 as y in the equation we have.

-2 = 2(-4) + b

Multiply.

-2 = -8 + b

Add 8 to both sides.

6 = b

Substitute 6 as b into the equation.

y = 2x + 6

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that none of the LED light bulbs are defective is 0.2213.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

Given the probability of a bulb being a failure is 14%, therefore, the probability of bulb passing the quality check is 86%.

Let the probability of success be defined as 0.14 for binomial distribution, and the probability for failure be 0.86. Therefore, The probability that none of the LED light bulbs are defective is

P(x=0) = ¹⁰C₀ (0.14)⁰ (0.86)¹⁰ = 0.2213

Answer:

f(x) = (x + 1)^2 + 2

Step-by-step explanation:

A parabola function has different forms:

standard form: f(x) = ax + bx + c^2

vertex form:  f(x) = a (x − h)^2 + k

Our equation that includes a horizontal translation is h

- negative h shifts right

- positive h shifts left

this graph shows a shift to the left by 1 so h = 1

Our equation that includes a vertical translation is k

- negative k shifts down

- positive k shifts up

this graph shows a shift to the up by 2 so k = 2

- a represents a compression / stretch which seems not to be in this graph

combine, f(x) = (x + 1)^2 + 2

A function assigns the values. The value of (p·p)(x) is x⁴ + 10x³ + 30x² + 25x.

A function assigns the value of each element of one set to the other specific element of another set.

Given p(x)= x²+5x, therefore, the value of (p·p)(x) can be written as,

(p·p)(x) = p(p(x))

            = (x²+5x)²+5(x²+5x)

            = x⁴ + 25x² + 10x³ + 5x² + 25x

            = x⁴ + 10x³ + 30x² + 25x
