Jasmine wants to have an equal quantity of forks and spoons, what is the least number of packages of forks jasmine should buy to

vlada-n [284]

Answer:

6 packages of forks

Step-by-step explanation:

If Jasmine wants to have an equal quantity of forks and spoons, we need to list the multiples of each quantity and determine the least common multiple (LCM).

Forks: 10, 20, 30, 40, 50, 60, 70, 80, 90

Spoons: 12, 24, 36, 48, 60, 72, 84, 96

The LCM in this example is 60. In order to have exactly 60 forks and 60 spoons, Jasmine will need to buy 6 packages of forks [60 ÷ 10 = 6] and 5 packages of spoons [60 ÷ 12 = 5].

X=15 is this a function how do you do it

Alexxandr [17]

9514 1404 393

Answer:

Step-by-step explanation:

The graph of this equation on an x-y plane is a vertical line. The input value x=15 maps to an infinite number of outputs (y-values). For a relation to be a function, each input can only map to one output.

x = 15 is not a function

50 points!! will mark brainliest to correct answer!!

Mamont248 [21]

I think your image for your regression line didn't show up, but judging from what I see, the answer should be:
<span>D) In step 4, Tameka mistakenly based the strength of the association on the slopes.

This is because the strength of the association is not determined by the slope of the regression line, but by how close the data points were to the actual line. The closer the points are to the actual regression line, the stronger the association.

Analyze the graph below.

qwelly [4]

A) Look at the coordinates of the four dots:

(0,0) (150,50) (300,100) (450,150)

Divide the x's by the y's ( other than the (0,0) one:

150/50 = 3

300 / 100 = 3

450/150 = 3

The ratio is the same for all of them and the first set is (0,0) so it is a direct variation graph.

B) The constant of proportionality is the ratio found above by dividing the X values by the Y values, which is 3.
