Answer:
42 girls
Step-by-step explanation:
Multiply 7 by 6 since 7 + 3 is 10 x 6 = 60.
Ok so
Corresponding sides and angles are a pair of matching angles or sides that are in the same spot in two different shapes.
It would basically be a ratio (7:14)
My best help would be this
If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides. This proves that the ratio of areas of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.
I really hope this helps, dont have a lot of time today to answer a lot of questions so have a great day and lmk if this helps!
Answer:
28 caffinated teas
Step-by-step explanation:
-46 - 4 = -50
answer is D. -50
The margin of error of a sample is given by:
B = z(α/2) σ/√n; where B is the margin of error = 25, z(α/2) is the level of significant = 1.96, σ is the standard deviation = 100 and n is the sample size.
25 = 1.96(100/√n)
100/√n = 25/1.96 = 12.76
√n = 100/12.76 = 7.84
n = (7.84)^2 = 61.47
Therefore, the smallest sample size required is 62 seniors.
