Answer:

Step-by-step explanation:

P(A) = 4/52 = 0.07692 which is bigger than 5%

5% = 0.05

0.07 is above 5% which is surprising.

The P(Spade A) = 1/52 = 0.01923 which is under 2% which meets your criteria.

Kim ran a mile in PE class. After resting for 1 hour her heart rate was 75 beats per minute. If her heart rate decreased by ⅖ ,
Andreas93 [3]

Answer:

125

Step-by-step explanation:

since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.

Steven is taking out a loan in the amount of $5,000. His choices are a 3-year loan at 5% simple interest and a 5 -year loan at 4
Andre45 [30]
I do believe it’s 250$

**The first choice:**
Principal: 5,000$
Rate(%): 5
Time(year): 3 years
A: 5,750$

**Second choice**
Principal: 5,000$
Rate(%): 4%
Time(year): 5 years
A: 6,000$

6,000-5,750=250$

Hope this helps!

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Write a probability model for this ex
allsm [11]

Answer:

We estimate to have 8.33 times the number 6 in 50 trials.

Step-by-step explanation:

Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.

P(X=k) = \binom{50}{k}(\frac{1}{6})^k(\frac{5}{6})^{50-k}

We will estimate the number of times that she spins a 6 as the expected value of this random variable.

Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.

Then , in this case, with n=50 and p=1/6 we expect to have \frac{50}{6} number of times of having a 6, which is 8.33.
