Given:

The inequality is:

3t+1\leq 5

To find:

The graph of the given inequality.

Solution:

We have,

3t+1\leq 5

Subtract both sides by 1.

3t\leq 5-1

3t\leq 4

Divide both sides by 3.

t\leq \dfrac{4}{3}

The value of t is less than or equal to \dfrac{4}{3}.

Since t\leq \dfrac{4}{3}, it means \dfrac{4}{3} is included in the solution, therefore there is a  closed circle at t=\dfrac{4}{3} and an arrow approaches to left from t=\dfrac{4}{3}.

Therefore, the correct option is A.

Nataliya [291]

Step-by-step explanation:

A study was to be undertaken to determine if a particular training program would improve physical fitness. A sample of 31 university students was selected to be enrolled in the fitness program. The researchers wished to determine if there was evidence that their sample of students differed from the general population of untrained subjects. The sample mean is 47.4 and a standard deviation of 5.3. The 98% confidence interval is determined and is given as, (45.2, 49.6) .

If the level of confidence is changed to 95%, then the confidence interval will become shorter but the p-value will not change because it is calculated using the test statistic. So the correct answer is (a).

If a line has a slope of -4 and a u intercept of 1, which of the following is it's graph?
3241004551 [841]
Well. I can't see the picture. But it would be decreasing at a rate of 4 so pick a point on the any line move over to the right one, then down four. And for the y intercept the line would intersect the y axis at positive one. Sorry if that's confusing

Zachary purchased a computer for 1800 on a payment plan. Three months after he purchased the computer, his balance was 1350. Fiv
zubka84 [21]

<u>Solution-</u>

Zachary purchased a computer for 1800 on a payment plan.  (Initial Money)

3 months after he bought the computer, his balance was 1350. (Money after 3 months)

Total money paid in 3 months = 1800-1350 = 450

Money paid per month = 450/3 = 150

5 months after he bought the computer, his balance was 1050.

Total spent = 1800-1050 = 750 = (5× 150)

So the equation that models the balance b after m months,

b = 1800 - m(150)

∴ Here, the slope signifies the constant monthly deduction of $150.

Monica and Lauren know that they will need a lot of money in order to make the purchases necessary for a successful bakery. They
xxTIMURxx [149]

Based on the model, the total amount of money in the joined account after the 5 weeks is $767.30

<h3>What are linear equations</h3>

Linear equations are equations that have constant rates

A linear equation is represented as:

y = mx+ b

In this case,

  • m represents the deposit per week
  • b represents the initial deposit

So, the linear equations are:

  • y =153.46x --- for Monica
  • y = 128.90+ 127.68x -- For Lauren

To calculate the number of weeks, when they have the same amount, we equate both equations

153.46x = 128.90 + 127.68x

Collect like terms

153.46x -127.68x= 128.90

25.78x= 128.90

Solve for x

x= 5

Substitute 5 for x in

y = 153.46x

y = 153.46 * 5

y = 767.30

Hence, it will take 5 weeks for both accounts to have the same amount of $767.30
