Answer 1

Answer:

Answer:

In Grade 8, 22% of students liked volleyball.

Step-by-step explanation:

Given:

The table representing the relative frequencies of different sports in different grades among the students.

Swimming Running Volleyball Row totals

Grade 8 0.14 0.18 0.22 0.54

Grade 9 0.17 0.24 0.05 0.46

Column totals 0.31 0.42 0.27 1

Relative frequency gives the ratio of the number of quantities of a particular kind and the total number of quantities.

From the above table, we can conclude the following points:

Grade 8:

14% liked swimming, 18% liked running and 22% liked volleyball. So, a total of 54% students liked playing sports.

Grade 9:

17% liked swimming, 24% liked running and 5% liked volleyball. So, a total of 46% students liked playing sports.

Combining students of grade 8 and 9:

31% liked swimming, 42% liked running and 27% liked volleyball.

From all the options available, we observe that, third option is only correct.

In Grade 8, 22% of students liked volleyball.

Suppose 70% of kids who visit a doctor have a fever, and 45% of kids with a fever have sore throats. What's the probability that a kid who goes to the doctor has a fever and a sore throat?I am stuck on this question, sadly I just did a lot of these for my exams but I forget how to solve it. Someone help??

Answers

To find the probability that a kid has both a fever and a sore throat, multiply the two probabilities together: 70% * 45% = 31.5%

70/100 = 0.7%
45/100 = 0.45%
0.7 x 0.45 = 0.31
0.31= 31%
31% is your answer sir

Andrew borrows $79,500 for 5 months on 6.30% interest rate in his saving account. calculate the simple interest

Answers

Equation i= p time r time T 79500 time .0630 time .42 Equal 21,035.7 simple interest Dos Doctor pepper on the interest, going back two time on the left which would become .0630 5 divide month of 12 which is .41666 Round to the nearest tenth which is .42

Final answer:

The simple interest on a $79,500 loan borrowed for 5 months at a 6.30% interest rate is $25,087.50.

Explanation:

To calculate the simple interest, we can use the formula: Simple Interest = Principal Amount * Rate * Time. In this case, the principal amount is $79,500, the rate is 6.30%, and the time is 5 months. First, convert the rate to a decimal by dividing it by 100: 6.30/100 = 0.063. Then, substitute the values into the formula: Simple Interest = $79,500 * 0.063 * 5 = $25,087.50.
