Sometimes writing can be an issue. Finding inspiration can be difficult... Might I suggest... A mystery perhaps. Or a fantasy.

You might be interested in

3x2=7 5x4=23 7x6=47 9x8=79 10x9=?

weeeeeb [17]

$3*2=7$ which means $3*2=3*2+1=6+1=7$
$5*4=23$ which means $5*4=5*4+3=20+3=23$
$7*6=47$ which means $7*6=7*6+5=42+5=47$
$9*8=79$ which means $9*8=9*8+7=72+7=79$

That's the patter we have here, but last one is $10*9=?$ which does not follow the pattern because first number is even and another is odd, which means that we can't implement pattern above to this situation, therefor we can check other side of the pattern.

$4*3=14$ which means $4*3=4*3+2=12+2=14$
$6*5=34$ which means $6*5=6*5+4=30+4=34$
$8*7=62$ which means $8*7=8*7+6=56+6=62$
$10*9=79$ which means $10*9=10*9+8=90+8=98$

and $98$ is the number you are looking for.

So fulfilled pattern you need to take in consideration would be:

$3*2=7$ which means $3*2=3*2+1=6+1=7$
$4*3=14$ which means $4*3=4*3+2=12+2=14$
$5*4=23$ which means $5*4=5*4+3=20+3=23$
$6*5=34$ which means $6*5=6*5+4=30+4=34$
$7*6=47$ which means $7*6=7*6+5=42+5=47$
$8*7=62$ which means $8*7=8*7+6=56+6=62$
$9*8=79$ which means $9*8=9*8+7=72+7=79$
$10*9=79$ which means $10*9=10*9+8=90+8=98$

If a person received a test score that is in the top 16% of all test scores, the persons Z-score must be

Tanzania [10]

Answer:

a score of 105 is one standard deviation above the mean

the rule says that 68% of a normally distributed population lies within one standard deviation of the mean...half above the mean and half below

so 34% are within one standard deviation above the mean

this means that 16% are above that value

Which of the following tables shows the correct steps to transform x2 + 8x + 15 = 0 into the form (x - p)2 = q?

Allisa [31]

Answer:

Step 1: x^2 + 8x + 15 + 1 = 0 + 1

Step 2: x^2 + 8x + 16 = 1

Step 3: (x + 4)^2 = 1

Step-by-step explanation:

You want the constant on the left to be the square of half the x-coefficient.

(8/2)^2 = 4^2 = 16

You already have a constant that is 15, so you need to add 1 to both sides of the equation. That is the Step 1 shown here. Step 2 is simplifying the result of Step 1. Step 3 is rewriting the trinomial as the square of a binomial.
