Answer:

47.75 + x Less-than-or-equal-to 50

= 47.75 + x ≤ 50

Step-by-step explanation:

Solving the above Question:

Not going over the 50 pound case mean, less than or equal to 50 pounds

Let the extra pound of weight be represented as x

Hence, the inequality equation that can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit =

47.75 + x ≤ 50

What is an equation of the line that passes through the points (1,3) and (8,5)?

slamgirl [31]

Answer:

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7

According to the sample size, it will be necessary to approximate the data through the normal distribution and through this calculate the standard deviation to obtain both the average, the standard deviation and the obtained deviation. Here the sample size is 40.

Approximately the distribution of proportion is a Normal distribution using the CLT. the mean will be 0.78, then we have that the standard deviation is,

$\sigma = \sqrt{\frac{p(1-p)}{n}}$

$\sigma = \sqrt{\frac{(0.78)(0.22)}{40}}$

$\sigma = 0.0655$

Then the distribution will be normal with the values of 0.78 to 0.0655 for the mean and the standar deviation respectively.

<em>Normal (0.78,0.0655)</em>

The distance around a meteor crater is 9,622 ft. find the diameter

vlada-n [284]

Since the distance around, or circumference, is 9, 622 ft. you need to use the formula for circumference to find the answer.
So...
9,622= $\pi$ ×diameter
9,622÷ $\pi$ = diameter
diameter = <span>3062.77772486 feet</span>

Math help i need to get 5 right......please

brilliants [131]

Answer:

f^-1(x) = x +6

Step-by-step explanation:

To find the inverse of the function

y = f(x)

solve the equation

x = f(y)

for y.

Here, you want ...

x = f(y)

x = (y -6)

x +6 = y . . . . . . add 6 to both sides

$\boxed{f^{-1}(x)=x+6}\\$
