Answer:<em>r = d/t</em>
Step-by-step explanation:
1. If we are solving for <em>r, </em>we need to have <em>r</em> on one side of the equation.
2. Divide by t on both sides = d/t=r
Answer: 5 8 7 9 5 6
Step-by-step explanation:
Because you go by which is closer to the denominator
Answer:
The student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
Answer:
a bag of chips equals $1
Step-by-step explanation:
(let x represent the chips)
$1.85 + 2x = $3.85
-$1.85 -$1.85
------------------------------
2x = $2
divide by 2
x = $1
Answer:
x2+16x=9 x 2 + 16 x = 9. To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b . (b2)2=(8)2 ( b 2 ) 2 . x^2+16x+9=0
Step-by-step explanation:
if this is not
