Answer:
41 feet
Step-by-step explanation:
We apply the theorem below:
If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
Let x be the perimeter of the smaller triangle
If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,
6:5=49.2:x
6/5=49.2/x
Cross multiplying
6x=49.2 X 5
6x=246
x=246/6=41
The perimeter of the smaller triangle is 41 feet

Answer:
Step-by-step explanation:
2.7*4=10.80
27*0.4=10.80 we multiplied 27 by 10 but divide 4 by 10
0.27*40=10.80
Probability of the student taking neither math nor science is 35 / 150 or 0.23
<u>Explanation:</u>
<u />
Given:
Total students = 150
Number of students taking maths = 95
Number of students taking science = 75
Maths + Science = 55
Probability of student taking neither math nor science = ?
Number of students taking only science = 95 - 55
= 40
Number of students taking only maths = 75 - 55
= 20
Number of students taking neither maths nor science = 150 - 40 - 20 - 55
= 35
Probability of the student taking neither math nor science is 35 / 150 or 0.23
The mean is 50 because if half get a "100" and the other half get a "0" the mean is 50. The standard deviation is 7.07 when you plug this into the 1-VARS stats on a calculator after putting this data in L1 List data set on the calculator.
a. 50
b. 7.07
