A sewing machine is at a 20% off sale. The original price was $340. How much does the sewing machine cost at a 20% off sale?

Anvisha [2.4K]

Answer:

272$

Step-by-step explanation:

Since it is at a sale of 20% off that means that we will have to subtract 100% from 20% which is 80%

Now to find the exact value, we will have to multiply 80%, or 0.80 with 340

0.80*340= 272$

Therefore our answer is 272$

Find the critical numbers (x-values) of the function y equals 2 x to the power of 5 plus 5 x to the power of 4 minus 19. Enter y

Zolol [24]

Answer:

$x=0,x=-2$

Step-by-step explanation:

From the question we are told that:

$y=2x^5+5x^4-19$

Generally the equation if differentiated is mathematically given by

$y'=10x^4+20x^3-0$

Where

y'=0

$10x^4+20x^3=0$

Factorizing,We have

$x=0,x=-2$

Therefore

The critical points are

$x=0,x=-2$

Answer: A. have the same slope

Step-by-step explanation:

b. bisect means right in half but not fully intersecting kinda looks like this _l_ *oh and it asked you to prove that they bisect so clicking on it don't really make sense*

c. perpendicular means there is four equal angels and that is 90 degree angels

d. parallel... well it's obviously not parallel because parallel are two lines that are exactly the same but never intersect

*intersect means touch*

Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out

ohaa [14]

In this scenario, the parameter is the sample proportion, which is of 0.7.

<h3>What is the parameter?</h3>

When a hypothesis is tested, the parameter is the information obtained from the sample, mean or proportion.

In this case, it is the <em>sample proportion</em>, which is the <u>number of desired outcomes divided by the number of total outcomes</u>.

She goes to the correct object in 70 of those 100 trials, hence:

$p = \frac{70}{100} = 0.7$

The parameter is the sample proportion, which is of 0.7.
