x = 9
Answer:
x = 9
Step-by-step explanation:
49 degrees and (5x + 4) are vertical lines, meaning they are congruent.
We can make an equation with this information:
(5x + 4) = 49
-4 -4
5x = 45

Answer:
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5\}[/tex]
[tex]n(S) = 5[/tex]
Required
[tex]P(x > 1\ and\ x < 2)[/tex]
[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:
[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]
Since it is a probability with replacement, we have:
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
For x > 1, we have:
[tex]x > 1 = \{2,3,4,5\}\\[/tex]
[tex]n(x > 1) = 4[/tex]
For x < 2, we have:
[tex]x < 2 = \{1\}[/tex]
[tex]n(x < 2) = 1[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
becomes
[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

What number should Rihanna use for the height of the parallelogram if she uses 28 inches for the base
Answers
Answer:
[tex]Height = 7in[/tex]
Step-by-step explanation:
Given
See attachment for parallelogram
[tex]Base = 28in[/tex]
Required
What is the height?
The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.
From the question, we have:
[tex]Base = 28in[/tex]
Also from the question, the difference between the two parallel sides is 7in.
Hence, the height of the parallelogram in 7in

According to the stem-and-leaf plot above, how many drivers travel below 80 miles hour per hour? A. 2 B. 6 C. 14 D. 5
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot
Required
Drivers that travel below 80 mph
A stem and leaf plot has the following syntax: Stem | Leaves
Take for instance:
7 | 2 3 4 7
The above represents 72, 73, 74 and 77
Using the above illustration, the attached leaf plot can be interpreted as:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
80 81... and so on
The drivers that drive below 80 mph are:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
And the frequency is: 12
Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)
