The Answer is D. If you solve the equation, you find that x=0, which means that the answer would be D. Infinitely many.

Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is th of the total time.
Hence, option D is correct.
Nothing. It is just two shapes on top of each other.
Answer:
The probability that a randomly selected compact car gets at least 40 miles per gallon is about 1.74%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
The probability that a randomly selected compact car gets at least 40 miles per gallon is about?
This is 1 subtracted by the pvalue of Z when X = 40. So
has a pvalue of 0.9826
1 - 0.9826 = 0.0174
The probability that a randomly selected compact car gets at least 40 miles per gallon is about 1.74%
