Answer:
Step-by-step Explanation:
Angle of depression is congruent to angle of elevation.
Therefore, angle of elevation of the given figure, which is opposite to x is 25°.
Adjacent length = 11 yd
Opposite length = x
Trigonometric ratio formula for finding x is shown below:
Multiply both sides by 11 to solve for x
(to the nearest tenth)
In this equation, we're trying to find if she has enough money to buy a $12 movie ticket.
We know that she buys a bag for $45.50, with a 5% tax rate. Let's calculate the total cost of the bag after tax.
45.50 · 1.05 = 47.775
Round to the nearest hundredths place
$47.78
She spent $47.78 on the bag.
She has $60, so calculate how much money she has left.
60 - 47.78 = 12.22
She has $12.22 left to spend.
This means that she has enough money to buy the movie ticket.
She would also have 22 cents left to spare.
Answer:
Yes, she has enough money to buy the movie ticket

Answer = a. 2
Degree of freedom df = (r – 1)(c – 1) = (2 – 1)(3 – 1) = (1)(2) = 1 x 2 = 2
Step-by-step explanation:
The degree of freedom of a one-dimensional chi-square statistic is df = n– 1, where ‘n’ is the number of categories or levels of the independent variable. But in this case, we are to analyze a two-way contingency table. This Chi-square test of independence uses a contingency table format. It is also referred to as a contingency table test. A (row X column) contingency table shows the observed frequencies for two categorical variables ( in the is case: TV shows and Gender) arranged in ‘r’ rows and ‘c’ columns. The sum of the observed frequencies is ‘n’, the sample size, that is, the row and column totals adds up to form a grand total ‘n’ which is the sample size. Since the rows and columns have been classified into mutually exclusive categories where the three TV shows will serve as the column heads and the male and female classification will serve as the rows, the degree of freedom for the test will be to multiply the individual degree of freedom of both row (r-1) and column (c-1) numbers in the (row X column) contingency table format for the test. Thus the degrees of freedom df = (r – 1)(c – 1), where r = number of rows(Male/Female) and c = number of columns (TV shows) .
Now, the gender here is 2 and the TV shows are 3
So, r = 2 and C = 3
Degree of freedom df = (r – 1)(c – 1) = (2 – 1)(3 – 1) = (1)(2) = 1 x 2 = 2
Answer: 'X' = 24 degrees
Step-by-step explanation:
5 times 'X' = 120 degrees (because the formula is base times height divided by 2).
120 divided by 5 = 'X'
= 24
'X' = 24 degrees
