Answer:
17.6 lbs
Step-by-step explanation:
1kg=2.2lbs
Multiply each side by 8
8kg=17.6 lbs
use one five dollar box then use 4 4 $ boxes then its five dollar boxes the rest of the way so it would be 59 5$ boxes then Four 4$ boxes
The answer is A
start by isolating the y variable
the rest of the work is shown here
Answer:
- P(x < 84) = 0.3085 or approximately 31%

<em>Hello to you from Brainly team!</em>
<h3>Given</h3>
- Mean grade μ = 86,
- Standard deviation σ = 4,
- Grade limit x = 84.
<h3>To find </h3>
- Probability of that a randomly selected grade is less than 84 or P(x < 84).
<h3>Solution</h3>
Find z-score using relevant equation:
Substitute values and calculate:
Using the z-score table find the corresponding P- value.
- P(x < 84) = 0.30854 or approximately 31%
M=230
m-80=150
add 80 to each sides
