Camden is 10 1/2 years old and Jane is (10 2/4 - 1 1/4) which equals 9 1/4 years
Answer:
Step-by-step explanation:
find the least common denominator for both fractions then combine them to find:
The complete question in the attached figure
Part a)
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6√2 cm
sin 45=AB/AC-----> AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm
the answer part a) isAB=6 cmPart b)
we know that
volume of the pyramid=(1/3)*Area of the base*height
area of the base=50 cm²
height=6 cm
so
volume of the pyramid=(1/3)*50*6----> 100 cm³
the answer part b) is 100 cm³
<span>The variance method is as follows.
-Sum the squares of the values in data set, and then divide by the number of values in data set
- From that, subtract the square of the mean (add all values and divide by number of values in the data set)
Our variance is
<span>
Since variance has to be 14, we set
and solve for m
quadratic formula
-4 doesnt' work as it is not a positive integer
m = 11
