I WILL MARK BRANLIEST FOR CORRECT ANSWER! The two-way frequency table contains data about how students access courses.
Traditional Online Row totals
Computer 28 62 90
Mobile device 46 64 110
Column totals 74 126 200
What is the joint relative frequency of students who use a mobile device in a traditional class?
23%
37%
46%
72%
Answers
The joint relative frequency is 23%. So option (1) is correct.
Joint relative frequency is defined as the ratio of a frequency that is not in the total row or column to the total number of values or observations. The marginal frequency in a two-way frequency table is the entry in the "total" for the column and the "total" for the row.
Given data:
Traditional Online Row totals
Computer: 28 62 90
Mobile device: 46 64 110
Column totals: 74 126 200
The joint relative frequency can be found by the formula:
= (Number of students using a mobile device in traditional class / Total Number of students) x 100%
Number of students using mobile devices in traditional class = 46
Total number of students = 200
= (46 / 200) x 100%
= 0.23 x 100%
= 23 %
Therefore the joint relative frequency of students in traditional classes using a mobile device is 23%.

what is 112/200 as a percentage
Answers
Answer:
56%
Step-by-step explanation:
112/200 as a percentage
112/200 = 0.56
0.56 as a percentage:
0.56 * 100 = 56%
Answer::
To do percentages with fractions,
divide the numerator by denominator to get a decimal,
so for example, your question, 112/200
112/200 is 0.56 decimal, and then to make it percent,
we multiply by 100,
how does that work?
you move two places to the right because 100 has two zeros
so 0.56 would be 56,
therefore the percent of 112/200 would be 56%

The roots for the given quadratic equation 2x² - 9 = 3x is {3, -1.5}.
What is a quadratic equation?
The Quadratic equations are second-order polynomial equations such as ax² + bx +c = 0 for x, where a ≠ 0.
It has at least one solution that could be real or complex.
The given equation is 2x² - 9 = 3x.
Now expressing in the form of ax² + bx + c = 0, we get
2x² - 3x - 9 = 0,
a = 2, b = -3, c = -9, Now solving the above equation, we get
2x² - 6x + 3x - 9 =0
2x(x - 3) + 3(x - 3) = 0
(x - 3)(2x + 3) = 0
x - 3 = 0 (or) 2x + 3 = 0
x = 3 (or) x = -1.5

The correct table is :

Given, f(x) = x+4
and g(x) = -2.f(x)

f(x) = 1+4
= 5
now g(x) = -2.f(x)
= -2(5)
= -10
for x=2
f(x) = 2+4
= 6
now g(x) = -2.f(x)

At the gym on Saturday, Reese ran 5 miles in the treadmill and then the completed 1 mile in the elliptical machine and burned 725 calories. On Sunday she ran 3 miles on the treadmill and completed 1 mile in the elliptical, and burned 505 calories. Write and solve a linear system to find the number of calories Reese burns on the machine
Answers
Answer:The equations are 5t + e = 725 and 3t + e = 505
Step-by-step explanation:Subtract equation (2) from equation (1) and you arrive at;
2t = 220
Divide both sides of the equation by 2
t = 110
Having calculated the value of t, substitute for the value of t into equation (1)
5t + e = 725
5(110) + e = 725
550 + e = 725
Subtract 550 from both sides of the equation
e = 175
The above calculations shows that the calories burned on each gym equipment are;
Treadmill = 110 per hour
Elliptical = 175 per hour

The probability that the sample mean is less than 200 pounds is 33% or 0.33
Given that,
The average annual meat consumption in the United States was 218.4 pounds, with a standard deviation of 42 pounds, and was normally distributed. A random sample of 30 individuals was chosen.
Mean (μ) = 218.4
Standard deviation (σ) =42
Probability = P(X< 200) = P[(X-μ ) / σ < (200-218.4) /42 ]
= P(z <-0.44 )

A line parallel to the line 4x + 7y = 49 - 2x + 4y must have a slope of - 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given a line that is 4x + 7y = 49 - 2x + 4y.
7y - 4y = - 2x - 4x + 49.
3y = - 6x + 49.

The probability that at least one of the shirts you draw will be pink 46/51.
What is probability?
The likelihood of an event happening is determined by probability. There are many instances in real life where we may need to make predictions about how something will turn out combination . The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not. In general, probability has many wonderful uses in games, in business to make forecasts based on likelihood, and in this emerging branch of artificial intelligence. By simply dividing the favourable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. The likelihood of an event occurring might range from 0 to 1.
Here the number of pink shirts=8
Number of green shirts=6
Number of red shirts=4
Here if you draw 2 shirts random then,
P(neither the shirt is blue) = [tex]\frac{6}{18} *\frac{5}{17}[/tex] = [tex]\frac{5}{51}[/tex]
Now the at least one of the shirt is pink then,
=> P( at least one shirt is pink)= 1-[tex]\frac{5}{51}[/tex] = [tex]\frac{51-5}{51}[/tex] = [tex]\frac{46}{51}[/tex]
Hence the probability that at least one of the shirts you draw will be pink 46/51.
