I believe it should be 0.5 x 7 as that is in a bracket and you have to deal with the bracket first before dealing with numbers outside the bracket.

Nathan rolls a number cube and records the result of each roll in the table.
Sergeeva-Olga [200]

Answer:

True statements:

A. The relative frequency of rolling  4 is \dfrac{2}{9}.

E. The experimental probability of rolling 1 is less than the experimental probability of rolling 6.

Step-by-step explanation:

Nathan made 11 + 16 + 14 + 20 + 12 + 17 = 90 rolls altogether. Consider all options:

A. The relative frequency of rolling  4 is

\dfrac{20}{90}=\dfrac{2}{9}.

This option is true.

B. The experimental probability of rolling 3 is \dfrac{14}{90}. The theoretical probability of rolling 3 is \dfrac{1}{6}=\dfrac{15}{90}. therefore, the experimental probability of rolling 3 is less than the theoretical probability. This option is false.

C. The experimental probability of rolling  2 is \dfrac{16}{90} and the theoretical probability of rolling  2 is \dfrac{1}{6}=\dfrac{15}{90}. The experimental probability of rolling  2 is smaller than the theoretical probability of rolling 2. Option C is false.

D. The relative frequency of rolling  5 is \dfrac{12}{90}=\dfrac{2}{15}\neq \dfrac{2}{13}. This option is false.

E. The experimental probability of rolling  1 is \dfrac{11}{90} and the experimental probability of rolling  6 is \dfrac{17}{90}. Since \dfrac{11}{90} then the experimental probability of rolling  1 is less than the experimental probability of rolling  6. This option is true.

F. The theoretical probability of rolling 1 is the same as the theoretical probability of rolling 6. This option is false.

Suppose you deposit $2,000 in savings account that pays interest at an annual rate of 4%. If no money is added or withdrawn, det
GarryVolchara [31]
Using I = PRT

$2500 - $2000 = $2000 × 0.04 × t

$500 = 80t

t = $500 ÷ 80
t = 6.25 years

so the answer is 6
