(3b) / (5b - 7) = 8/11
cross multiply
8(5b - 7) = 11(3b)
40b - 56 = 33b
-56 = 33b - 40b
-56 = -7b
-56/-7 = b
8 = b
Answer:
11 students out of 902 responded above 35
Step-by-step explanation:
Using z-score we can find what percentage of student will be above 35. Using this percentage we can calculate how many students out of 902 scored above 35.
Mean = u = 26
Standard deviation = s = 4
Target Value = x = 35
Formula for the z score is:

Using the values in this formula, we get:

Using the z table we can find the percentage of values that would be 2.25 standard deviations above the mean in a normal distribution. Using the z-table we get this value to be 0.0122 or 1.22%
Thus 1.22% of the values will be above 35.
1.22% of 902 is 11 (rounded to nearest whole number)
Thus 11 students out of 902 responded above 35
Total cost = Price of juice + price of chocolate + tax = 10 + 10 + [(16/100) x 20]
= 20 + 3.2
= $23.2
Answer:
the answer would be f: y=-x^3 -4
Elaboration:
You don't show if there's a 4th answer so I'm just assuming you have one, but if there is no option, then I apologize.
Explanation:
y = -x^3 flips the equation, since you are putting the coefficient of x to a negative
y = -x^3 - 4 lowers the equation by 4 on the y axis, setting the equation shown in the graph.
Answer:
Step-by-step explanation:
1) Probability - the measure of the likelihood of an event
2) Probability model - Assigns a probability to all possible non-overlapping outcomes in a sample space; the sum of the probabilities in a probability model is 1
3) Outcome - Any possible result of an experiment
4) Favorable outcome - Outcome for a specific event
