. Ann can ice a cupcake in 30 seconds. Sarah can ice a cupcake in 40 seconds. Working

Mathematics
1 answer:

Answer:

600seconds

Step-by-step explanation:

If Ann can ice a cupcake in 30 seconds, then the total number of cupcakes iced by ann is t/30 cupcakes

Similarly, If Sarah can ice a cupcake in 40 seconds, then the total number of cupcakes iced by Sarah is t/40 cupcakes,

For them to ice 35cupcakes together, then;

t/30 +  t/40 = 35

where t is the times taken by both of them to ice 35cupcakes

Find the LCM

40t+30t/1200 = 35

70t/1200 = 35

7t/120 = 35

t/120 = 5

t = 120 * 5

t = 600

This shows that it will take them both 600seconds to ice 35cupcakes

Which Mean Absolute Deviation represents more consistency? 15.2 or 10.9
Firdavs [7]

Answer:

10.9

Step-by-step Explanation:

The Mean Absolute Deviation of a given data set tells us how far apart, on average, each data value is to the mean of the data set.

The smaller the Mean Absolute Deviation of a given data set is, the closer each data value is to the mean. This also implies less variability of the data set.

Invariably, the smaller the M.A.D, which connotes less variability, the more consistent the data set is.

Therefore, a M.A.D of 10.9 represents more consistency than a M.A.D of 15.2

Need help please this question is very confusing i would love some help
Natali [406]

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 3, - 6), thus

y = a(x + 3)² - 6

To find a substitute (0, 0) into the equation

0 = 9a - 6 ⇒ a = \frac{6}{9} = \frac{2}{3}

y = \frac{2}{3}(x + 3)² - 6 ← in vertex form

Expand (x + 3)² and distribute by \frac{2}{3}

y = \frac{2}{3}(x² + 6x + 9) - 6

  = \frac{2}{3} x² + 4x + 6 - 6

  = \frac{2}{3} x² + 4x  ← in standard form
