Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
A. 14 + 2 × 5 = 14 + 10 = 24 ≠ 22
B. (14 + 2) × 5 = 16 × 5 = 80 ≠ 22
C. 24 - 6 ÷ 3 = 24 - 2 = 22
D. (24 - 6) ÷ 3 = 18 ÷ 3 = 6 ≠ 22
<h3>Answer: C.</h3>
i think its C im half of one hundered % sure its that
Answer:
c. 0.1151
Step-by-step explanation:
d) the probability that, on average, fish are larger than 86 centimeters in length.The area under part of a normal probability curve is directly proportional to probability and the value is calculated as
z = (x₁−x) /σ
where z = propability of normal curve
x₁ = variate mean = 86cm
x = mean of 80cm
σ = standard deviation = 5cm
applying the formula,
z= (86-80)/5
z = 6/5 =1.2
Using a table of partial areas beneath the standardized normal curve (see Table of normal curve, a z-value of 1.2 corresponds to an area of 0.3849 between the mean value. but, because the standard curve has 0.5, then will minus 0.3849 from 0.5= 0.5 - 0.3849 = 0.1151
Thus the probability of a fish are larger than 86 centimeters in length is 0.1151
I don't know what your story is, but in a story, usually a problem would build tension.
Hope this helps!! :)
