7 1/5 = 7 + 1/5
= 7/1 + 1/5
= (7/1 * 5/5) + 1/5
= 35/5 + 1/5
= 36/5
= 36 ÷ 5
= 7.2
9+9 is 18 24-18 is 6 6 divided by 2 is 3 so the width is 3 centimeters
(a) q=0
You would simplify the equation.
3+9=12
12+q=12
Then you would eliminate 12 from both sides, by subtracting.
q=0
Answer: his score 131 points
Step-by-step explanation:
Assuming the scores in the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = standardized test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 110 points
σ = 10 points
Looking at the normal distribution table, the z score that corresponds to the 98 percentile is 2.06
2.06 = (x - 110)/10
Cross multiplying, it becomes
2.06 × 10 = x - 110
2.06 = x - 110
x = 20.6 + 110
x = 130.6
Approximately, x = 131
First, look at the ratio. And out of 2&3&4, 2 is the smallest. So, change the 2 to 15, 3 to X, 4 to Y. Like this down below
15:X:Y
Now, if 2=15, 1=15÷2, which is 7.5
If one is 7.5, the X=3×7.5=22.5
Y=4×7.5=23
Add them all up, 15+22.5+23=60.5
The perimeter is 60.5
