First you’d separate into 2 inequalities so it would change to t-4/-3>-2 then you’d solve it for inequalities t-4/-3>-2 then you’d find the intersection which would be the answer: T (3,10)

Answer:

x > 3

x < 10

Step-by-step explanation:

\frac{x - 4}{ - 3}  <  \frac{1}{3}

You first have to seperate into two inequalities and solve separately.

Multiply by -3 and solve for x. Dont forget to switch inequality symbol because you multiply by negative. You should get x > 3

\frac{x - 4}{ - 3}   >   - 2

Same thing here. Don't forget to switch inequality symbol. You should get x < 10

The first term of an arithmetic sequence is -3 and the 15th term is 53. What is the common difference of the sequence?
Fittoniya [83]

Answer:

c = 4

Step-by-step explanation:

Let the common difference be c.  Then a(n) = -3 + c(n-1).  Since a(15) = 53, a(15) = -3 + (15-1)c = 53.  Therefore, -3 + 14c = 53, or 14c = 56; c = 4.

Select the correct answer. Will is at a shirt sale where he can buy one and get a second one for 40 percent off. He wants to buy
maxonik [38]

Answer:

C

Step-by-step explanation:

Givens

Original cost = 29 dollars.

Discount = 40% on the second shirt.

Formula

cost after discount = (2 × list price) – (list price × discount percentage)

Solution

Cost after discount = 2 * 29 - 29*40/100

Cost after discount = 58 - 11.60

Cost after discount = 46.40

On a unit test in a statistics class, the teacher determines that the mean test grade was 77.5 with a standard deviation of 5.2.
katovenus [111]

Answer: B. This student's test grade was 2.4 standard deviations above the mean test grade.

====================================================

Explanation:

The z score tells us how far away the raw score is from the mean. This distance is in terms of standard deviations.

  • z = 1 means we're 1 standard deviation above the mean
  • z = 2 means we're 2 standard deviations above the mean

and so on.

Negative z scores indicate the raw score is below the mean.

  • z = -1 means we're 1 standard deviation below the mean
  • z = -2 means we're 2 standard deviations below the mean

and so on. So that's why z = 2.4 indicates the students test grade was 2.4 standard deviations above the mean.
