Answer:
x = 6 and x = -6
Step-by-step explanation:
x² = 36
to solve for 'x' we need to take its square root but must do the same to the other side:
x = [tex]\sqrt{36}[/tex]
square roots have both positive and negative roots:
6 x 6 = 36
(-6) x (-6) = 36
x = ±6

1. Ms. Hogan and Ms. Brantley believe that less than 30% of students at Olympia High School completed their math homework last week. They enlist the help of all the math teachers and select a random sample of students and determine the percentage of those who completed their homework last week. 2. A company claims they have a diagnostic test that can detect cancer 90% of the time for those who have cancer. 150 people who have been diagnosed with cancer are given this diagnostic test. 108 of the individuals is identified as having cancer. Does this study provide convincing evidence that percentage of those diagnosed by this test is different than the company claims
Answers
Answer:
Yes
Step-by-step explanation:
Number 1 isnt asking a question.
2. If you divide 108/150= 0.72%
That is 18% percent off from what they claim which is quite a bit. Im not sure what is considered the "close enough" percentage but 18 is definitely more.

Answer:
a=10
Step-by-step explanation:
use a^2+b^2=c^2
(a+2)^2+(a-5)^2=(a+3)^2
a^2+4a+4+a^2-10a+25=a^2+6a+9
2a^2-6a+29=a^2+6a+9
a^2-12a=-20
a^2-12a+20=0
quadratic formula→(12+/-8)/2
a=10 or 2
2 is not an option because 2-5=-3 which isn't possible in this case.
so a=10
Apply Pythagorean theorem
(a-5)²+(a+2)²=(a+3)²a²-10a+25+a²+4a+4=a²+6a+9a²-6a+29=6a+9a²-12a+20=0a²-10a-2a+20=0a(a-10)-2(a-10)=0(a-2)(a-10)=0a=2,10There is a side a-5 so 2 is not a answer

Hello i need help with my assignment thank you in advance and i know you deserve the point
Answers
Answer:
1) a = 51, 2) b = 57, 3) c = 53, 4) e = 49 d = 131, 5) f = 33, 6) g = 79, 7) h = 42 j = 47, 8) m = 59 k = 17 i = 104, 9) n = 55
Step-by-step explanation:
1.
You see that angle HJK has a total degree angle of 115, half of the angle is already stated to be 64 degrees, so you would just have to find the remainder. 115 - 64 = 51
2.
The question follows the same format, when you see the square in the corner it generally means that it is a 90-degree angle. So following the same steps as last time angle b would be 90 - 33 = 57
3.
Whenever there is a flat line given the angle is equal to 180 degrees, think of it as putting two 90 degree angles back to back. So if they equal 180 angle c would equal 180 - 127 = 53
4
This question is just a little different when you see crossing perpendicular lines angles across from each other equal the same amount, so angle d would be 131. Finding angle e is not hard either, back to question 3 for when it was just a straight line the same logic can be applied here. e would equal 180 - 131 = 49

Step-by-step explanation:
The zeros of the polynomial are all the values of [tex]x[/tex] for which the function [tex]f(x)=0[/tex]
Therefore,
[tex]x = 0[/tex]
[tex]x = -8 \implies x + 8 = 0[/tex] (twice)

To solve a mixed fraction multiplication problem, you must:
Convert the fractions into improper fractions. (If the fractions are proper, you can skip this step.)Simplify the fractions If possible. (If it is not possible, you can skip this step.)Multiply the fractions (numerator with numerator and denominator with denominator).After reviewing how to multiply an improper fraction, let's solve the multiplication problem.
1 1/6 x 6/11=> (6 + 1)/6 x 6/11 [According to step 1]=> 7/6 x 6/11 => 7/1 x 1/11 [According to step 2]=> 7 x 1/11 x 1 [According to step 3]The solution to the multiplication problem is 7/11.
[tex] \bf \nrightarrow \: 1 \frac{1}{6} \times 6 \frac{6}{11} [/tex]
Convert the mixed fraction to improper fraction by Multiplying the denominator with the integer and adding the numerator to the product of denominator and integer
[tex] \sf \underbrace{1 \frac{1}{6} = \frac{7}{6} }[/tex]
Now, Multiply the fractions
[tex] \bf \: \frac{7}{6} \times \frac{6}{11} [/tex]
Multiply the numerators and denominators
