Step-by-step explanation:

4 \times  \frac{3}{4} (x + 8) > 4 \times  \frac{1}{2} (2x + 10) \\ 3( x + 8) > 2(2x + 10) \\ 3x + 24 > 4x + 20 \\ 4 > x

so ans is :

Answer:

(–∞, 4)

Step-by-step explanation:

  • 3/4(x + 8) > 1/2(2x + 10)
  • 3(x+8) > 2(2x+10)
  • 3x+24>4x+20
  • 3x-4x>20-24
  • -x>-4
  • x<4
  • x ∈ (–∞, 4)

Laura wrote and solved the following expression to find the total number of beads Lina has if there are 6 beads in each packet.
bulgar [2K]
<h3>The number of beads lina has is 31</h3><h3>Laura made a mistake by adding the constant 7 and variable 4b</h3>

<em><u>Solution:</u></em>

Given that,

Laura wrote and solved the following expression to find the total number of beads Lina has

There are 6 beads in each packet

7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Given that, There are 6 beads in each packet

Substitute b = 6

7 + 4(6)

Simplify

7 + 24

Add

31

Thus, she has a total of 31 beads and not 66 beads

Laura made a mistake by adding the constant 7 and variable 4b

But a constant and variable cannot be added

What is the slope and y intercept of the following linear equation:y=1/3×-2
gulaghasi [49]

Answer:

Step-by-step explanation:

The general formula for slope-intercept form is y = mx + b

We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2

Note:

If youre ever asked for the x-intercept, make y equal to zero and solve for x.

Consider a sample on the waiting times (in minutes) at the billing counter in a grocery store to be 15, 24, 18, 15, 21, 20, 15,
Ipatiy [6.2K]

The mean, median, and mode is 18.5, 19, 15.

We have

15, 24, 18, 15, 21, 20, 15, 22, 19, 16, 15, 22, 20, 15, and 21.

In ascending order:

15, 15, 15, 15, 15, 16, 18, 19, 20, 20, 21, 21 ,22, 22, 23

n=15(number of observations)

The median is \frac{n+1}{2} \\= > \frac{16}{2} =8th term

Median: 19.

Mean:

\frac{sum}{n}\\ \frac{278}{15} \\=18.5

Mode: 15.
