Please help urgent plzz1.find the mean of the data set excluding multiple of number 10 between 1 to 50?

2.find the mean of the data set excluding multiple of number 3 between 1 to 10?

Answers

Answer 1

Answer: This can be done quickly using Excel or a scientific calculator. For problem no. 1, the data that are multiples of 10 in the set are 10, 20, 30, 40 and 50 and the number of data points in the set are 45 since the data set is from 1-50 excluding the 5 numbers that are multiples of 10.

Mean=[(sum of all numbers from 1 to 50)-10-20-30-40-50]/[50-5]=25

The second problem is similar. The multiples of 3 here are 3, 6 and 9. There are 10-3 data points.

Mean = [(sum of numbers from 1-10)-3-6-9)]/[10-3]=5.2857

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers does Mrs Smith have

Answers

x = markers
y = colored pencils

12x = y

x= 72
y = 6

Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 (12x = 6) which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.

Slope = 4/3, (-2, 11)

Answers

Answer:

y = $(4)/(3)$ x + $(41)/(3)$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = $(4)/(3)$ , hence

y = $(4)/(3)$ x + c ← is the partial equation

to find c substitute (- 2, 11) into the partial equation

11 = - $(8)/(3)$ + c ⇒ c = $(41)/(3)$

y = $(4)/(3)$ x + $(41)/(3)$ ← equation of line

$\sf(3)/(5)(3y+15)$

Distribute 3/5:

$\sf(3)/(5)*3\rightarrow(3*3)/(5)\rightarrow(9)/(5)$

$\sf(3)/(5)*15\rightarrow(3*15)/(5)\rightarrow(45)/(5)\rightarrow9$

So we have:

$\boxed{\sf(9)/(5)y+9}$
