Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (9, 2) and (x₂, y₂ ) = (9, - 5)

m = $\frac{-5-2}{9-9}$ = $\frac{-7}{0}$

Since division by zero is undefined then the slope is undefined.

This indicates that the line is vertical.

A football field measures 300 feet in length. It can also be expressed as approximately 5. 7 times 10 Superscript n miles. If th

CaHeK987 [17]

The most reasonable value of n n = -2.

We have given that the length of the football field = 300 feet

It can also be expressed as approximately $5.7\times 10^{n}miles$

<h3>What is the value of one mile in feet?</h3>

Also, 1 mile = 5280 feet....(1)

We have to find 1 feet so divide both side of equation (1)by by 5280 we get,

$1feet=\frac{1}{5280}$

Now, for 300 feet is,

$300feet=\frac{1}{5280}(300)$

$300 feet=0.056818181=0.057miles$

In scientific notation we have,

$300 feet=5.7\times 10^{-2}miles$

Therefore we get n = -2.

Lisa buys a television for $4185. if the sales tax is $292.95. what percent is sales tax?

Romashka-Z-Leto [24]

Answer:

Sales tax = 7%.

Step-by-step explanation:

Let x be the percent of sales tax.

We have been given that Lisa buys a television for $4185. The sales tax is $292.95.

We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.

$\frac{x}{100}*4185=292.95$

Let us multiply both sides of equation by 100.

$100*\frac{x}{100}*4185=100*292.95$

$x*4185=29295$

$x=\frac{29295}{4185}$

$x=7$

Therefore, sales tax is 7%.

Let us cross check our answer by calculating 7% of 4185.

$7\%\text{ of } 4185=\frac{7}{100}\times 4185$

$7\%\text{ of } 4185=0.07\times 4185$

$7\%\text{ of } 4185=292.95$

We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1

lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0 and 1. The probabilities add up to one.

Given probabilities are:

$\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x$

The sum of these probabilities will be equal to 1.

So,

To find x,

$\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}$

The value of x is 1/5
