How do you do this math

Mathematics
1 answer:
Ber [7]3 years ago
5 0

Answer:

Step-by-step explanation:

tanR = \frac{\text{Opposite side}}{\text{Adjacent side}}

        = \frac{PQ}{QR}

        = \frac{10}{24}

        = \frac{5}{12}

sinR = \frac{\text{Opposite side}}{\text{Hypotenuse}}

        = \frac{PQ}{PR}

        = \frac{10}{26}

        = \frac{5}{13}

cosR = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

        = \frac{QR}{PR}

        = \frac{24}{26}

        = \frac{12}{13}

Complete Question

The picture of the stem plot National  and American League is shown on the first uploaded image

Answer:

The value is \= x  = 50.14

Step-by-step explanation:

From the question we are told that

The stem plot for National League is

            2\ \ \ \ \ 9\\3\ \ \ \ \ 1 \\4\ \ \ \ \ 2\  6\  7\  8\  8\\5 \ \ \ \ \ 3\  5\  5\  5\\6 \ \ \ \ \ 3\  3\  7\\7

The  sample size is  n =  14

Generally the stem plot is interpreted in this manner

   The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with

  for example 4th row

 5           3 5 5 5

is equivalent to

53 55 55 55

Generally the mean for the national league is mathematically represented as

           \= x  = \frac{29 + 31 + \cdots + 67}{14}

=>         \= x  = \frac{702}{14}

=>         \= x  = 50.14

What is the surface area of a storage box that measures 15 centimeters by 12 centimeters by 8 centimeters?
Leya [2.2K]
L = 15
w = 12
h = 8

Surface Area = 2(lw + wh + lh)
S.A. = 2(15*12 + 12*8 + 15*8)
S.A. = 2(180 + 96 + 120)
S.A. = 2(396)
S.A. = 792 cm^2
