Answer:

maya - 6 min per puzzle

amy - 7 min per puzzle

maya would finish first since her unit rate is smaller. for example, it takes maya 30 for 5 but it would take 35 for 5.

A person gets on and off a bathroom scale four times. The four readings (in pounds) are 148, 151, 150, and 152. Each time after
Ganezh [65]

Answer:

See explanation below

Step-by-step explanation:

Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of

148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25

We could estimate the uncertainty as <em>the standard error SE </em>

\bf SE=\frac{s}{\sqrt{n}}  

where  

<em>s = standard deviation of the sample </em>

<em>n = 4 sample size. </em>

Computing s:

\bf s=\sqrt{\frac{(146-148.25)^2+(149-148.25)^2+(148-148.25)^2+(150-148.25)^2}{4}}=1.479

So, the uncertainty is 1.479/2 = 0.736

<em>It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight. </em>

What is the rate of change between (29,9) and (33,10)?
Tema [17]

Answer:

\frac{1}{4}

Step-by-step explanation:

The rate of change is a measure of the slope

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (29, 9) and (x₂, y₂ ) = (33, 10)

m = \frac{10-9}{33-29} = \frac{1}{4} ← rate of change
