sineoko [7]

Answer:

The equation $35x+93\frac{3}{4}=190$ gives average time spent on 35 rehearsals.

Step-by-step explanation:

Please consider the complete question.

The play director spent 190 hours preparing for a play. That time included attending 35 rehearsals that took varying amounts of time and spending $93\frac{3}{4}$ hours on other responsibilities related to the play. What question does the equation $35x+93\frac{3}{4}=190$ help answer?

Since time spent on each rehearsal is 35 hours, so time spent on 35 rehearsals would be $35x$ .

$93\frac{3}{4}$ hours is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.

Now let us solve our equation step by step.

$35x+\frac{375}{4}=190$

$35x=190-\frac{375}{4}$

$35x=\frac{760}{4}-\frac{375}{4}$

$35x=\frac{760-375}{4}$

$35x=\frac{385}{4}$

$35x=96.25$

Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.

Therefore, equation $35x+93\frac{3}{4}=190$ gives average time spent on 35 rehearsals.

For a recent year, the following are the numbers of homicides that occurred each month in New York City: 38, 30, 46, 40, 46,

lubasha [3.4K]

Answer:

Each month is equally likely

Step-by-step explanation:

Given that for a recent year, the following are the numbers of homicides that occurred each month in New York City:

38, 30, 46, 40, 46, 49, 47, 50, 50, 42, 37, 37.

We have to check whether it is equally likely for each of the 12 months

Set Hypotheses as

H0: All months are equally likely

Ha: atleast two months are not equally likely

(Two tailed chisquare test at 5% significance level)

This is a test for chi square goodness of fit and so assuming H0 to be true

we divide the total equaly among 12 months as expected

Observed Expected Chi square

Total 512 512 10.375

df=11

p value = 0.497

Since p >0.05 our alpha we accept H0

Each month is equally likely

Kaylis [27]

Answer:

90 degrees

Step-by-step explanation:

Step 1: State what is known

Notice that the 2 lines cut the square in half and create 4 congruant triangles. We know a full circle is 360 degrees and the intersection is a perfect circle formed by 4 angles. We can find the angle AEB by dividing 360 by 4 which gives you 90 degrees
