Answer:
median is 117.5
Step-by-step explanation:
9 - x² < 0
<u>-9 -9</u> <u> </u><u /> to remove 9 deduct it from both sides<u></u>
- x² < -9
<u> ÷ -1 ÷-1 </u> to remove the negative sign, divide both sides by -1
x² < 9
<u> √x² < √9</u> to remove the exponent of 2, find the square root of both sides.
x < 3 Choice A.
To check:
9 - x² < 0
9 - 3² < 0
9 - 9 < 0
0 < 0
Answer:
Step-by-step explanation:
I believe it should be 252 total pretzels so since theres nine friends and each one gets 28 so 28 x 9 equals 252. Hope it helps :)
Answer:
90 between 1000 and 9999
Step-by-step explanation:
The first digit cannot be 0. It can be nine other digits.
The second digit can be anything between 0 and 9.
To be palindromic the 2nd and 3rd digits must be the same.
And in addition, the 1st and 4 numbers must be the same.
So the answer is 9 * 10 = 90. That does seem too small, but try making a palindrome with the restrictions I have outlined. None of the examples you have given beginning with 8 are palindromic.
8118 is palindromic
8998 is also palindromic
9009 is palindromic
2002 is palindromic
There are only 90 of them.
7^2 - 3(4-2)^0 - 2(7+3) + 3^2
= 49 - 3 - 20 + 9
= 35
hope it helps
P.S
any number to the 0 power is always equal 1
