4x - 3 = -x - 13
4x + x = -13 + 3
5x = -10
x = -10/5
x = -2
y = 4x - 3
y = 4(-2) - 3
y = -8 - 3
y = -11
solution is (-2,-11)
Answer:
$613.80
Step-by-step explanation:
7% of 660 = 0.07 × 660 = 46.2
660 - 46.2 = 613.80
I assume you mean: Order the following from least to greatest:
17/9, 15 divided by 6, 30, and 3^3
17/9 = 1 8/9
15/6 = 2 1/2
3^3 = 9
So it would be: 17/9, 15 divided by 6, 3^3, and 30
Make necessary adjustments if it was actually 6/30; the wording was confusing.
When there is a dotted line it means its either this symbol < or this one >. The y-intercept is 25. Now go up 4 spaces and one space to the left that is your slope. We call that "Rise over Run". So the last choice is your final answer.
I hope this helps love! :)
Answer:
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean 490 mg and variance of 400.
This means that 
What is the probability that a randomly selected pill contains at least 500 mg of minerals?
This is 1 subtracted by the p-value of Z when X = 500. So



has a p-value of 0.6915.
1 - 0.6915 = 0.3085
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals
