The total Number of Stamps that John has is; 798 Stamps

<h3>How to Solve Ratio Problems?</h3>

John, Mike and Tom shared a box of stamps in the ratio of 6:7:11.

This means that, the fraction of the whole each have are respectively;

John's Fraction = 6/(6 + 7 + 11) = 6/24

Mikes Fraction = 7/24

Tom's Fraction = 11/24

If the total number of stamps is x, and Tom had 532 more stamps than mike, then it means that;

11x/24 = 7x/24 + 532

11x/24 - 7x/24 = 532

x/6 = 532

x = 3192

Thus;

John has; (6/24) * 3192 = 798 Stamps

Suppose that 76% of americans prefer coke to pepsi. a sample of 80 was taken. what is the probability that at least seventy perc
vladimir2022 [97]
The standard deviation of the sample proportion is:
\sqrt{ \frac{0.76(1-0.76)}{80}} =0.048
The z-score for 0.7 is:
z= \frac{0.7-0.76}{0.048} =-1.25
Reference to a standard normal distribution table shows that the probability that at least 70% of the sample prefers coke to pepsi is 0.8944 or 89.44%.

Alberto ran a race at a speed of 9 meters per second. Omar had a 6 meter head start and ran at a speed of 7 meters per second. B
zloy xaker [14]

Answer: Alberto run 27 meters.

Time taken By Alberto=3 seconds


Step-by-step explanation:

Let d be the distance Alberto ran to catch Omar.

Then, distance ran by Omar=x-6

Also, \text{Time}=\frac{\text{Distance}}{\text{Speed}}

Since, both started running at the same time.

Time taken By Alberto=\frac{x}{9}

Time taken By Omar=\frac{x-6}{7}

Now, at the point they meet time taken by both is equal.

\frac{x}{9}=\frac{x-6}{7}\\\Rightarrow\ 7x=9(x-6)\\\Rightarrow7x=9x-54\\\Rightarrow9x-7x=54\\\Rightarrow\ 2x=54\\\Rightarrow\ x=27

Hence, Alberto run 27 meters.

Time taken By Alberto=\frac{27}{9}=3 seconds

Basically, the denominator will always be the number outside of the radical and the numerator will always be your exponent. If it’s one, you don’t put it in because if there is no exponent, it’s an invisible one
