Answer:
b
Step-by-step explanation:
3(x + 2) - 2x + 4
3x + 6 - 2x + 4
combine like terms:
1x + 10
The question is incomplete, let's take an hypothetical value for the Area of the circle ;
Let the are aid the circle = x in²
Answer:
Kindly check explanation
Step-by-step explanation:
The scale factor = 5/4
The initial area of square = x in²
The area of the circle after dilation will be :
Scale factor * initial area of circle
5/4 * x in²
Area after dilation = 5/4(x) in²
Just substitute the original value of the square for X in the solution to obtain the exact answer.
Hello!
To solve the inequality, you'll need to multiply 7 with x and -2. Once you've done that you'll be one step closer to solving.
7x-14<-5
Next, you'll need to add 14 to -5. Once you have that done, -5 should now be 9.
7x<9
Now you need to divide both sides by 7. Once you've done that you'll have an inequality of...
x< 9/7
I hope this helps!
Answer:
For this case we want to test if life expectancy in country 1 is more than 10 years lower than in country 2, (alternatibe hypothesis), so then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
Or equivalently:
Null hypothesis:
Alternative hypothesis:
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".

Answer:
-322.25 is less than -241.75, but you when paying someone back, you want to pay a lower number, so when you pay someone back, you want to pay the bigger negative number because you are technically paying less.
