The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the d

Darya [45]

Answer:

19 measures the median

Step-by-step explanation:

The dot plot is not shown, but the question can still be answered.

We have:

$Samples: 18, 18, 18, 18, 20, 20, 22, 23$

$n = 8$

Calculate the median position using:

$Median = \frac{n + 1}{2}th$

$Median = \frac{8 + 1}{2}th$

$Median = \frac{9}{2}th$

$Median = 4.5th$

4.5th means the median is the mean of the 4th and 5th item.

We have:

$4th = 18$

$5th = 20$

So:

$Median = \frac{18 + 20}{2}$

$Median = \frac{38}{2}$

$Median = 19$

¿Cuál es el valor de la razón de cambio cuando tenemos un vaso con agua a temperatura ambiente al congelador por 15 minutos?

grandymaker [24]

Answer: $2 \°C/min$

Step-by-step explanation:

The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:

Temperature in $\°C$

Time in $min$

Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature $\Delta T$ divided by the time variation $\Delta t$ .

Hence, assuming the ambient temperature of the glass is $30 \°C$ and the elapsed time $15 min$ we have:

$\frac{\Delta T}{\Delta t}=\frac{30 \°C}{15 min}=2 \frac{\°C}{min}$

vesna_86 [32]

<u>Given</u>:

The measure of ∠EGF is 51°

We need to determine the measure of ∠EHF

<u>Measure of ∠EHF:</u>

By inscribed angle theorem, we know that, "if two inscribed angles of a circle intercept the same arc then the angles are congruent".

Applying the theorem, we have that the two inscribed angles of a circle intercepting the same arc are ∠G and ∠H

Then, the two angles are congruent.

Thus, we have;

∠G ≅ ∠H

Therefore, the measure of ∠G = ∠H = 51°

Hence, the measure of ∠EHF = 51°
