Determine the unknown measures of the triangle shown. Round to the nearest tenth, if necessary. x = in. y ≈ ° z ≈ ° A right triangle is shown. The hypotenuse has a length of x. The other 2 sides have lengths of 24 inches and 7 inches. The angle opposite to the side with length 7 inches is y, and the angle opposite to the side with length 24 inches is z.

Answers

9514 1404 393

Answer:

x = 25y = 16.3°z = 73.7°

Step-by-step explanation:

The length of the hypotenuse can be found using the Pythagorean theorem:

  x² = 7² +24² = 49 +576 = 625

  x = √625 = 25

__

The angles can be found from the sine relation.

  Sin = Opposite/Hypotenuse

  sin(y) = 7/25

  y = arcsin(7/25) ≈ 16.3°

The acute angles in a right triangle are complementary, so ...

  z = 90° -16.3° = 73.7°

Answer:

x = 25 in.

y ≈ 16.3 degrees

z ≈ 73.7 degrees

it took 5 hours to mow 6 yards. at the rate, how many yards can be mowed in 20 hours

Answers

Answer:

24 yards

Step-by-step explanation:

Given: 5 hours to mow 6 yards.

To find: At the same rate, how many yards can be mowed in 20 hours?

Solution: There are lots of different ways of solving this but I will show you setting up fractions to know how much 5 hours are for 6 yards let "x" be the variable

Step 1: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{6}{5} = \frac{x}{20} \\\\20*\frac{6}{5} = 20 * \frac{x}{20}[/tex]

Step 2: Cancel multiplied terms that are in the denominator

[tex]20*\frac{6}{5} = 20 * \frac{x}{20}\\\\20 * \frac{6}{5} = x[/tex]

Step 3: Multiply the numbers

[tex]20 * \frac{6}{5} = x\\\\24 = x[/tex]

Step 4: Move the variable to the left

[tex]24 = x\\\\x = 24[/tex]

Therefore, 24 yards can be mowed in 20 hours.

Complete question :

The time married men with children spend on child care averages 6.4 hours per week (Time, March 12, 2012). You belong to a professional group on family practices that would like to do its own study to determine if the time married men in your area spend on child care per week differs from the reported mean of 6.4 hours per week. A sample of 40 married couples are surveyed to collect the hours per week the husband spends on child care. The sample mean is 7.0 hours per week, and the sample standard deviation is 2.4276 hours per week. Use Excel to answer the following questions. a. What are the hypotheses if your group would like to determine if the population mean number of hours married men are spending in child care differs from the mean reported by Time in your area? b. What is the test statistics of the population mean? c. Using a .05 level of significance, what are the critical values? d. What is your conclusion?

Answer:

H0 : μ = 6.4

H1 : μ ≠ 6.4

Test statistic = - 1.563

Critical value = ±2.023

Fail to reject the null ; there is no significant evidence to support the claim that mean number of hours spent differs

Step-by-step explanation:

H0 : μ = 6.4

H1 : μ ≠ 6.4

Test statistic, Z :

(Xbar - μ) / (s/√n)

(6.4 - 7) / (2.4276/√40)

-0.6 / 0.3838372

T= -1.563

α = 0.05 ; df = n - 1 = 40 - 1 = 39

Critical value(0.05, 39) = ±2.023

|T| > +Tcritical ; Reject the Null

Since |T| < +Tcritical ; then we fail to reject the Null, hence, we conclude that there is no significant evidence to support the claim that mean number of hours spent by married men in child care differs.
