As The Line 3x + y > 1 involves the inequality ( > ) :

✿ The Shaded Area of the Line 3x + y > 1 is Away from the Origin

✿ The Line 3x + y > 1 is represented by a Dotted Line

As The Line y ≤ x + 2 involves the inequality ( ≤ ) :

✿ The Shaded Area of the Line y ≤ x + 2 is Towards from the Origin

✿ The Line y ≤ x + 2 is represented by a Dark Line.

So, The Graph which fulfills the above Conditions is :

The thing that is required for a <span>proportional relationship would be that no matter what the order of the relationship is, it should be that if the function of x increases then x would increases as well or vice versa. Hope this helps. Have a nice day. Feel free to ask more questions. </span>

Graph h(x) = 4x + 4 + 3.<br> Help me plz

saveliy_v [14]

Answer:

h(x)=4x+7

Step-by-step explanation:

4+3 can be added together if they do not have a variable. h(x)=4x+7. Plug in different x coordinates and solve for h(x). Now graph those points.

Approximately 54% of mathematics students do their homework on time. In a class of 250 students, what is the mean, variance, and

sleet_krkn [62]

Answer:

A) Mean = 135 Variance = 62 Standard Deviation = 8

Step-by-step explanation:

Given that :

Proportion (p) = 54%

Sample size (n) = 250

Using Normal approximation :

Mean = np

Mean = 250 * 0.54 = 135

Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46

Variance = (250 * 0.54 * 0.46) = 62.1 = 62

Standard deviation = √variance = √62.1

Standard deviation = 7.8803553 = 8

Jennifer and Kamlee are walking to school. After 20 minutes, Jennifer has walked 4/5 miles. After 25 minutes, Kamlee has walked

Nimfa-mama [501]

Answer:

Jennifer's speed is 2.4 miles/hour

Kamlee's speed is 2 miles/hour

Step-by-step explanation:

To find their speed,

Speed can be determined from the formula below,

$Speed = \frac{Distance}{Time}$

Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)

For Jennifer,

Distance = 4/5 miles

Time = 20 mins (Convert to hour)

∴Time = (20/60) hour = 1/3 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{4/5 miles}{1/3hour}$

$Speed = \frac{4}{5} \times \frac{3}{1}$

$Speed = \frac{12}{5}$

$Speed = 2.4 miles/hour$

Hence, Jennifer's speed is 2.4 miles/hour

For Kamlee,

Distance = 5/6 miles

Time = 25 minutes (Convert to hour)

Time = (25/60) hour = 5/12 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{5/6miles}{5/12 hour}$

$Speed = \frac{5}{6} \times \frac{12}{5}$

$Speed = 2 miles/hour$

Hence, Kamlee's speed is 2 miles/hour

This is a little difficult for me! Can someone explain?

ch4aika [34]

Answer:

We can write sin 21° as 1200 / x and also 0.36 so we can write:

1200 / x = 0.36

1200 = 0.36x

x = 1200 / 0.36

x ≈ 3333 ft
