$\frac{x}{45} = \frac{20}{100}$

To get x which is the 20% tip

1. 45×20 = 900

2. 900÷100=9

3. 9 is the tip

What number is represented by 4x²+17x+2 if x=10?

Fynjy0 [20]

Answer:

at x = 10, $4x^{2} + 17x + 2 = 572$

Step-by-step explanation:

The given equation is $4x^{2} + 17x + 2$

Here, lets substitute the value of x = 10

So, the equation simplifies to ,

$4 \times (10)^{2} + 17(10) + 2$

= (4 x 100) + 170 + 2 = 400 + 170 + 2

= 572

So, at x = 10, $4x^{2} + 17x + 2 = 572$

A craft vendor must sell at least $300 worth of merchandise to make a profit. Scarves sell for $10 each and hats sell for $20 ea

valina [46]

There is a missing graph in the problem given. However, we can simply solve the equation using the given data.

Items to be sold: scarves and hats. Minimum of 20 items sold in all.
Scarves sell for 10 each and hats sell for 20 each. Must sell at least 300 worth of merchandise to make profit.

Let s represent scarves and h represent hats.

10s + 20h > 300
s + h > 20

We use inequality because the problem states "at least".

s + h = 20
10s + 20h = 300

s = 20 - h
10(20-h) + 20h = 300
200 - 10h + 20h = 300
10h = 300 - 200
10h = 100
h = 100/10
h = 10

s = 20 - h
s = 20 - 10
s = 10

s + h > 20
10 + 10 > 20

10s + 20h > 300
10(10) + 20(10) > 300
100 + 200 > 300

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. The foundation chair for a hosp

slavikrds [6]

Answer:

For this case we want to test if the mean number of filled overnight beds is over 523. If X represent our random variable "number of filled overnight beds", the system of hypothesis are:

Null Hypothesis: $\mu \leq 523$

Alternative hypothesis: $\mu > 523$

And for this case after conduct the test is FAIL to reject the null hypothesis. So then we can conclude that the claim that the number of filled overnight beds is over 523 is not statistically supported

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Solution to the problem

For this case we want to test if the mean number of filled overnight beds is over 523. If X represent our random variable "number of filled overnight beds", the system of hypothesis are:

Null Hypothesis: $\mu \leq 523$

Alternative hypothesis: $\mu > 523$
