Answer:

30 times

Step-by-step explanation:

We have 2 outcomes, heads and tails, so to get the probability of getting heads, divide 60 by 2 to get 30. This is theoretical. Hope this helps!

Bond [772]

Answer:

A. 10.4 mph

Step-by-step explanation:

26÷2.5=10.4

Double checking your answer:

If she does 10.4 miles in an hour, she can get 20.8 in two hours

then you add half of how much she can go in an hour which is 5.2 (10.4÷2)

you add it together, and you will get 26 miles in total

(20.8+5.2=26)

Answer:

The probability  that an applicant does not get a job if he or she has an interview is 20%.

Step-by-step explanation:

  • If the applicant has been interviewed, then she/he belongs to the group of 20 people that had an interview.
  • 16 of the 20 people who were interviewed were offered a job, which means that 4 of the 20 people interviewed were not offered a job.
  • Then, 4/20= 20% of the people who were intervied did not get a job, which means that the <u>probability that an applicant does not get a job if he/she were interviewed is 20%</u>.
  • Pat attention: this probability results from analysing the probability of getting a job once you have had an interview (this condition restricts our attention to the group of 20 people who had an interview, and not to the hole group of 500 people who did apply for the job).

Solve for x. (1 point) −3x + 2b &gt; 8 x &lt; the quantity negative 2 times b plus 8 all over negative 3 x &gt; the quantity neg
masha68 [24]

Given:

-3x+2b>8

To find:

The value of x.

Solution:

We have,

-3x+2b>8

To find the value of x, we need to isolate x on one side.

Subtract 2b from both sides.

-3x>8-2b

Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.

\dfrac{-3x}{-3}

x

The required inequality for x is x.

Therefore, the correct option is A.
