Please Solve 8=1/3(a+5)
e-lub [12.9K]

Answer:

a = 19

Step-by-step explanation:

Given the equation of:

\displaystyle{8 = \dfrac{1}{3}(a+5)}

First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:

\displaystyle{8 \cdot 3= \dfrac{1}{3}(a+5) \cdot 3}\\\\\displaystyle{24= a+5}

Subtract both sides by 5 to isolate the variable:

\displaystyle{24-5=a+5-5}\\\\\displaystyle{19=a}

Therefore, the value of a is 19.

PLEASE HELP FAST I NEED THIS QUICKLY
son4ous [18]

Answer:

0.833

Step-by-step explanation:

1. locate which vertical column of the graph we are referring to:

  • student 7

2. calculate the total number of trials student 7 did:

  • if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 6
  • 5 + 1 = 6

3. refer back to the question:

  • the question states: "what is the experimental probability that the tack lands point-up"

4. interpret the graph:

  • of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up.
  • therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)

5. converting from fraction to decimal:

  • all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form.
  • to convert to decimal form, simply divide the top number by the bottom number
  • 5 ÷ 6 = 0.833

therefore, the experimental probability that the tack will land point-up, is 0.833

hope this helps :)
