MATH HELP PLEASE!!!! WILL MARK BRAINLIEST

Mathematics
1 answer:
Ierofanga [76]2 years ago
7 0

Answer:

Prime:  x^2 + 17x - 30.

Difference of 2 squares:  256x^4 - 49x^2.

GCF:  4x^2 - 24x + 144.

Perfect Square trinomial:  4a^6 - 28a^3 + 49

Factoring Trinomial: b^2 + 5b - 36.

Step-by-step explanation:

1.  x^2 + 17x - 30 will not factor.

2.  256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)

3.   4x^2 - 24x + 144 = 4(x^2 - 6x + 36).

4.   4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.

5.    b^2 + 5b - 36 = (b + 9)(b - 4).

Illusion [34]

Answer:

A Type I error would occur if there was no evidence of an improvement on the national exam but there really was improvement.

Step-by-step explanation:

A type 1 error simply occurs when we incorrectly reject a true null hypothesis. In the scenario above, An experiment was conducted in other it know if there is sufficient evidence to support a claim that a new teaching method developed improves students score. If this claim is actually true in the real sense. However, after conducting a statistical test, we conuded that there was no sufficient evidence to support her claim of improvement using the new method, hence, the claim was rejected. By rejecting the claim, a true null has been rejected. Hence, a type 1 error has been committed.

Dr. David Smith lived 1/13 of his life as a child. He spent 4/39 of his life preparing for an outstanding
stich3 [128]

Answer:

40 14/25 years

Step-by-step explanation:

Well, this certainly is fun.

First, to find the fraction of the doctor's life which 13 years represents, subtract the fractions from 1 (and in this case l stands for lifetime):

13 = (1 - (\frac{1}{13} + \frac{4}{39} + \frac{1}{2}))(l)

13 = (\frac{25}{78})(l)

So, multiply this equation by the reciprocal of 25/78 to isolate one of l:

13(\frac{78}{25}) = l

l = 40\frac{14}{25} years

15 Points!! Please help and explain how to solve them!! I really want to understand it
babymother [125]
1) idk I got none of your options
2)p=42,000÷(1+0.0225÷12)^(12×5)
P=37,535.04
3)PVAO=4900*12[(1/0.029)-(1/0.029*(1+0.029)^10]=504145.41..compare with 500000
So the answer is D
4)lucas

Peton
55×72.03=3,961.65
((4,192.10−3,961.65)
÷3,961.65)×100=5.8%
So the answer is D

What is 23% of 256? please help
Anastasy [175]
So first you need to turn the percent into a decimal. So 23% would be 0.23 because you divide 23 by 100 to turn it into a decimal. Now you multiply 0.32 and 256. So:

0.23 *256=58.88 

So your answer would be 23% of 256 is 58.88. I hope this helps! =)
