Answer:

-1

Step-by-step explanation:

-5^2 is -25 because you have to do exponents first, so 5^2 is 25. Add a negative symbol there, it becomes -25.

For the denominator, we do the exact same process, except a little different. Since there are parentheses around the negative five, we have to apply the negative symbol on the 5 before we do the exponents. After, we do -5^2 which is 25 because when you are multiplying negative, you always get a positive.

When we are all done with that, we put the numerator over the denominator to get -25/25, which is equivalent to -1.

Write an equation for a line perpendicular to y = -5x – 4 and passing through the point (15,5)
stiv31 [10]

Answer:

y=1/5x+2

Step-by-step explanation:

In perpendicular lines the slopes are negative reciprocals so the slope of other line is 1/5x

And they intersect at (15,5) to find the y intercept(b)

y=1/5x+b

5=(1/5)(15)+b

5=3+b

b=2

Here are the prices of five new pairs of hockey skates, in dollars: 59, 60, 65, 99, 175. The standard deviation is about $49. If
Phoenix [80]

Answer:

The standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

Step-by-step explanation:

The prices are given to be : 59, 60, 65, 99, 175

Standard deviation = $49

Now, if we add or subtract any constant value to each of the terms then the standard deviation remains unchanged.

But, we add a new price in the given data that is $450

\text{New standard deviation = }\sqrt{\frac{\sum (\bar{x}-x_i)^2}{n}}\\\\\bar{x}\text{ is the mean of data after adding 450 and}\\x_i\text{ are the price values of the sample data}

Hence, Standard deviation is calculated to be 139.5

Therefore, the standard deviation of the new data will be increased as compared to the previous standard deviation of the data.

What is the answer? X=
Minchanka [31]

Answer:

5

Step-by-step explanation:

\because \triangle ACB \cong \triangle DCE... (given) \\\therefore \angle A \cong \angle D... (c.a.c.t)\\\therefore m\angle A = m\angle D\\\therefore 50\degree = 10x\\\\\therefore x = \frac{50\degree}{10}\\\\\huge \orange {\boxed {\therefore x = 5\degree}}

You and your friends want to rent a limo on prom night.
kolezko [41]

Answer:

4 hours

Step-by-step explanation:

if you have $350

you'd subtract 50 por que it's a one time fee.

which leaves with 300

then you'd divide 75 into 300

to see how many hours you'd receive with the remaining of your $300.

which is four.
