First one: x>5
second one: x≥5
im pretty sure its right
Hope this helps love! :)
Answer:
1.5
Step-by-step explanation:
Applying,
Z = (x-μ)/σ................. Equation 1
Where Z = Z score for a height of 67 inches, x = height, μ = mean of the height, σ = standard deviation of the height.
From the question,
Given: x = 67 inches, μ = 64 inches, σ = 2 inches.
Substitute these values into equation 1
Z = (67-64)/2
Z = 3/2
Z = 1.5

Answer:
52°
Step-by-step explanation:
If it is a right triangle, one interior angle is 90°, and we are also given the interior angle of 38°. The sum of any triangles interior angles will always be 180°.
90 + 38 = 128
180 - 128 = 52
The third angle is 52°
