Samira used the calculator to find 254.3 × 2.5. Which statement best describes her work? Samira is correct. Samira is incorrect. The calculator should not give an answer that includes a decimal point. Samira is incorrect. The correct answer should only be about twice as much as 254.3, and the number on the screen is much larger. Samira is incorrect. The answer on the screen is not large enough to be the correct answer.

A line is drawn so that it passes through the points (-5,-3) and (-7,-5). What is the slope of the line?
Answer:
1
Step-by-step explanation:
The required slope of the line is 1 which passes through the points (-5, -3) and (-7, -5).
What is the slope of the line?The slope of a line is defined as the change in the y-coordinate (the "rise") divided by the change in the x-coordinate (the "run").
To determine the slope of the line that passes through the points (-5, -3) and (-7, -5), we can use the formula:
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Let
x₁ = -5, y₁ = -3
x₂ = -7, y₂ = -5
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Plugging in the coordinates of the two points, we get:
slope = (-5 - (-3)) / (-7 - (-5))
Simplifying this expression gives us:
slope = -2 / -2
Which simplifies to:
slope = 1
Therefore, the slope of the line that passes through the points (-5, -3) and (-7, -5) is 1.

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. What is the probability that a randomly selected student studies for a test and gets a B or higher?
Answer:
The probability that a randomly selected student studies for a test and gets a B or higher is 33%.
Step-by-step explanation:
What we know:
There is a 55% chance a student will get a B or higher on the tests.
60% of students study for the tests.
P(A∩B) = P(A) * P(B)
P(A∩B) = 3/5 * 11/20
P(A∩B) = 33/100 = 0.33 = 33% chance to get a B when studying for a test.
Probabilities are used to determine the chances of passing a test and getting a B grade
The probability that a selected student studies, and gets B or higher is 33%
Let the events be represented as follows:
A: The event that a student gets B or higher in a test if they study B: The event that a student gets B or higher in a test if they do not studySo, we have:
[tex]\mathbf{P(A) = 55\%}[/tex]
[tex]\mathbf{P(B) = 20\%}[/tex]
60% of the students study.
So, the probability that a student studies, and gets B or higher is:
[tex]\mathbf{Pr = P(A) \times 60\%}[/tex]
Substitute 55% for P(A)
[tex]\mathbf{Pr = 55\%\times 60\%}[/tex]
Multiply
[tex]\mathbf{Pr = 0.33}[/tex]
Express as percentage
[tex]\mathbf{Pr = 33\%}[/tex]
Hence, the probability is 33%

(6e-3f-3/4) in a equivalent expression
Answer:
Step-by-step explanation:
(6e-3f-3/4) contains two terms which do not involve fractions and one fractional term (3/4).
We can safely remove the parentheses. Then:
(6e-3f-3/4) => 6e - 3f - 3/4
That is "an equivalent expression."
We could go further and create one equivalent fraction. Multiply the first two terms by 4/4, obtaining:
24e 12f 3 24e - 12f - 3 3(8e - 4f - 1
------ - ------ - ----- => ---------------------- => -------------------

Answer: -3
Step-by-step explanation:
What is the coefficient: 4 - 2y
The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
So,
The coefficient of y is -2.
Hence, we can say that the coefficient of the variable y in the given equation is -2.

if 4/3 x 3/4 = 5k, then k = ?
Answer:
k= 1 /15 x^3
Step-by-step explanation:
4/3 x 3/4 = 5k
5k= 1 /3 x^3
k= 1 /15 x^3
The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.
To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.
Multiplying the fractions on the left side:
(4/3) × (3/4) = 12/12 = 1
Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.
Dividing both sides of the equation by 5:
1/5 = k
Hence, the value of k in the given equation is 1/5.

The relationship between length x, length 15 and angle 32 is as follows:
[tex]tan \theta = \frac{opp}{adj}[/tex]
So, we have:
[tex]tan\ 32= \frac{x}{15}[/tex]
Cross multiply:
[tex]x =15*tan\ 32[/tex]
[tex]x = 15 * 0.6248693519[/tex]
[tex]x = 9.3730402785[/tex]
[tex]x = 9.4[/tex] --- approximated
Similarly:
The relationship between length y, length 15 and angle 32 is as follows:
[tex]cos \theta = \frac{adj}{hyp}[/tex]
So, we have:
[tex]cos\ 32= \frac{15}{y}[/tex]
Cross Multiply:
[tex]y * cos\ 32= 15[/tex]
Solve for y
[tex]y = \frac{15}{cos\ 32}[/tex]
[tex]y = \frac{15}{0.84804809615}[/tex]
[tex]y = 17.6876760506[/tex]
