32gal/min equals how many qt/h

1 answer:

7 0

There are sixty minutes in an hour.

32 x 60 = 1,920

That is 1,920 gallons in an hour.
Four quarts make a gallon, so therefore taking 1,920 gallons per hour and multiplying it by 4 will give us the number of quarts per hour.
7,680 quarts per hour.

Alternatively, 32 x 4 = 128
That is quarts per minute.
128 x 60 = 7,680

seraphim [82]

Answer:

No mode

Median 7

Step-by-step explanation:

Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

The percentage of titanium in an alloy used in aerospace castings is measured in 51 randomly selected parts. The sample standard

luda_lava [24]

Answer: $0.3849$

Step-by-step explanation:

Given : sample size : n= 51

sample standard deviation : s= 0.46

Significance level : $\alpha=1-0.95=0.05$

Using chi-square distribution, the critical values will be :

$\chi^2_{\alpha/2, n-1}=\chi_{0.025,\ 50}=71.4202$

$\chi^2_{1-\alpha/2, n-1}=\chi_{0.975,\ 50}=32.3574$

Confidence interval for population standard deviation ( $\sigma$ ) :

$\sqrt{\dfrac{s^2(n-1)}{\chi^2_{\alpha/2}}}$

Substitute all the values , we get

$\sqrt{\dfrac{(0.46)^2(50)}{71.4202}}$

Hence, the 95% two-sided confidence interval for σ : $0.3849$

Domain of the graphed relation

VashaNatasha [74]

"The domain is the set of all first elements of ordered pairs (x-coordinates).The range is the set of all second elements of ordered pairs (y-coordinates).Only the elements "used" by the relation or function constitute the range.
