ZanzabumX [31]

Answer:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes besides the difference of breasts implants.

Step-by-step explanation:

This study casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes.

If the null and alternate hypothesis are formulated as

H0 : silicone breasts implants cause illness in smokers, drinkers and hair dyed people

against the claim

Ha: silicone breasts implants do not cause illness in smokers, drinkers and hair dyed people

then there would be no doubt .

But as the null and alternate hypothesis are

H0: silicone breast implants cause illness in women

against the claim

Ha: silicone breast implants do not cause illness in women

This suggests that both categories of women have same characteristics.

But actually both categories do not have same characteristics. The breast implant women also , smoke, drin and dye hair.

So when the characteristics are changed the illness maybe caused by some other characteristics.

Answer:

False,

(-4, -1) is not a solution of the given system of equations

Step-by-step explanation:

Given the system of equations:

$3x+8y =20$ .......[1]

$-5x+y =19$ ......[2]

To determine (-4, -1) is a solution

Substitute x = -4 and y = -1 in both the equations, if they both satisfied then it is a solution.

$3(-4)+8(-1)=20$

⇒ $-12-8 = 20$

⇒ $-20 = 20$ False.

$-5(-4)+(-1)=19$

⇒ $20-1 = 19$

⇒ $19=19$ True.

Since, the given statement is not true

because the ordered pair (-4, -1) does not satisfy the given system of equations.

postnew [5]

Answer:

15000 - 750x

Step-by-step explanation:

Holly is trying to save $25, 000 to put a down payment on a condominium. She started with $10,000 and saved an additional $750 each month.

Let

y = dollars

x = number of months

Since she started her savings with $10, 000 her remaining amount to pay will be 25000 - 10000 = $15000 .

The amount will also be reducing by $750 per month

Therefore,

How far she is from her goal can be represented with the equation

15000 - 750x

Which system of equations is represented by the graph?

o-na [289]

The answer is the third option, which is:
<span> y = x^2 + 5x + 3
6x + y = −27
The explanation is shown below:
1. When you solve this problem you have the following solution:
x=-6
y=9

x=-5
y=3

2. As you can see the solution corresponds with the graph shown above.
3. You can give value to the variable x of the first equation and values to the x of the second equation, and plot each point obtain. You will see that the parabola and the line, touch each other at the points (-5,3) and (-6,9)</span>
