Answer:
There would be 80 boys.
Step-by-step explanation:
2 to 3 can be simplified to 1 to 1.5, if we divide 120 by 1.5 we get 80. We also know this is true because there would be 50% more girls than boys: 80*1.5=120
Answer:
The inverse of f(x)=3x+1 is f(x)−1=13x−13
Step-by-step explanation:
Step-by-step explanation:
We know that,
Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,
The percent of his sales that were less than or equal to 84 inches, is
Therefore, the remaining 100-94.5=5.5% were more than 84 inches.

Step-by-step explanation:
Answer:
x: 148 degrees
y: 32 degrees
Step-by-step explanation:
Hello!
To find the unknown values of these angles, we must understand the concept of intersecting lines. When calculating the angles of the intersecting lines, SQP and RQT are identical values since they are on the opposite ends of each other when given these sorts of problems. This helps us find y being 32 degrees.
On the other hand, to find x, we just need to focus on the line PQR. it's a line, which means that it is 180 degrees. Since SQP is 32 degrees, SQR, or the angle that is x, should be 180-32, which is 148
