Answer:

4. A.

14. A. 38.4 mph

<u>(I estimated the line to be 1.5 inches. Measure the line IRL so I can adjust the answer)</u>

15. D.

16. B.

17. A.

Step-by-step explanation:

4. Rearrange the numbers; 44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56

Minimum = 44

First Quartile = 46

Median = 50

Third Quartile = 55

Maximum = 56

14. 12 × 8 = 96. 96 × 1.5 = 144

144/1 ÷ 15/4 = 144/1 × 4/15 = 576/15 = 38.4

15. 35(2) + [ -1/2(15) ] = 35(2) - 1/2(15)

16. The new numbers for 540 students are

8/60 = 72/540 Walked: 72

7/60 = 63/540 Car: 63

3/60 = 27/540 Bicycle: 3

42/60 = 378/540 Bus: 378

17. 280 × 9 = 2,520

Increase by 25% = 125% of the total

2,520 × 1.25 = 3,150

3,114 - 3,150 = -36

The distance between the two houses is 546m. I can walk 1.3 m/sec using the formula d=rt how long does it take to get to the hou

My name is Ann [436]

D=546m. r=1.3m/sec. 546m=1.3m/sec(t).
546m divided by 1.3m/sec = t = 420 sec (the meters will cancel out, leaving the answer to just seconds).
420 seconds divided by 60sec/min = 7 minutes.

What is the y-intercept of the graph of the equation 6x-5y=-15

guapka [62]

Answer:

y-intercept = 3

Step-by-step explanation:

The given equation is :

6x-5y=-15

We can rewrite it ib slope-intercept form as follows :

Dividing both sides by 5

$\dfrac{6x}{5}-y=\dfrac{-15}{5}\\\\\dfrac{6x}{5}-y=-3\\\\\dfrac{6x}{5}+3=y$ .....(1)

The general equation of slope-intercept form is:

y = mx +c ....(2)

On comparing equation (1) and (2) we get :

m = 6/5

c = 3

Hence, the y intercept of the graph of the equation is 3.

Which statement shows the associative property of addition?

AleksAgata [21]

The associative property of addition is shown in equations where the order in which the evaluation is made does not change the result, providing the numbers remain in the same order. Option B demonstrates this.

12.) m=26
19-(-7)/-1-(-2)=26

13.) 14
8-(-20)/5-3=14

14.) -4/5 is the slope
Count rise over run and always make sure whether to add a negative based on the direction of the line. In this situation, the line is negative so there is a negative sign present.
