For the straight line defined by the points (3, 59) and (5, 87), determine the slope and y-intercept. do not round the answers.

Margarita [4]

(3,59)(5,87)
slope = (87 - 59) / (5 - 3) = 28/2 = 14 <== ur slope

y = mx + b
slope(m) = 14
use either of ur points...(3,59)...x = 3 and y = 59
now we sub and find b, the y int
59 = 14(3) + b
59 = 42 + b
59 - 42 = b
17 = b <=== ur y int (0,17)

If the mean heights of three groups of students consisting of 20,16 and 14 students are 167m, 150m and 1.40m respectively find t

Aleonysh [2.5K]

Answer:

1.54 m

Step-by-step explanation:

Given information:

Three groups of students

20 students with a height of 1.67 m
16 students with a height of 1.50 m
14 students with a height of 1.40 m

⇒ Total number of students = 20 + 16 + 14 = 50

To find the mean height of all the students, divide the sum of all the students' heights by the total number of students:

$\begin{aligned}\implies \sf mean\:height & =\dfrac{(20 \times 1.67)+(16 \times 1.50)+(14 \times 1.40)}{50}\\\\ & = \dfrac{33.4+24+19.6}{50}\\\\ & = \dfrac{77}{50}\\\\ & = 1.54\:\: \sf m\end{aligned}$

Therefore, the mean height of all the students is 1.54 m

Samuel orders four DVDs from an online music store. Each DVD costs $9.99. He has a 20% discount code , and sales tax is $6.75% .

leonid [27]

$34.66
9.99 x 4 = $39.96
minus 20% is 31.96 unless you round up which would be $31.97
6.75% sales tax on 31.96 is $2.1573
6.75% sales tax on 31.97 is $2.1579

The number line is shown below. Which decimal is shown on the number line by point M?

Snezhnost [94]

Answer:

The number associated with point M is 5.64

Step-by-step explanation:

notice that there are 10 divisions marked with ticks in between 5.6 and 5.7. So that means that the difference between these two numbers : 5.7 - 5.6 = 0.1

has been subdivided into 10: 0.1/10 = 0.01

Therefore we can assign a real number to each of the ticks by adding successively increments 0.01 (starting from the left "5.6"), and learn which number corresponds to the point M.

Please see the attached image that illustrates this, and shows in red the number assigned to the tick where point M is located: 5.64
