Answer:
7. 69° 8. 118°
Step-by-step explanation:
to know
- isosceles triangles have the base angles congruent
- the sum of angles in a triangle is 180
180 -42 = 138 sum of the two base angles
138 /2 = 69 is one base angle
31*2 = 62 are the 2 base angles
180 -62 = 118° vertex angle
Answer:
31.75 cm is equal to 12.5 in
Step-by-step explanation:
Answer: the z score is 1
Step-by-step explanation:
Since the head circumference for boys at birth is normally distributed,
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = head circumference for boys at birth.
µ = mean head circumference
σ = standard deviation
From the information given,
µ = 34.5cm
σ = 1.3 cm
For a boy born with a head circumference of 35.8cm, the z score is
z = (35.8 - 34.5)/1.3
z = 1
